FROM THE DEAN’S DESK

We all recognize

that there is more to a college experience than just academics. Our students gain critical leadership and team-building skills through participation in student professional organizations, residential hall administration and campus charity activities. The educational experience should include many avenues of learning. Although the classroom lecture is an important component of most courses, many students choose to supplement their educational portfolio with internships, study abroad programs and research projects.

Embarking on a research project under the direction of a professor is a unique experience for an undergraduate student. Research projects require our students to be creative, self-motivated, organized and responsible, and can enhance understanding of fundamental concepts. Students selected for these projects are our best and brightest, and often show a tendency toward entrepreneurship. Many of our students have been involved in patents, publications and start-up companies, and have generated additional funding based on their work. These students often choose to continue their education in our graduate programs.

Consider Kate Stuckman. As a sophomore majoring in electrical and computer engineering, she turned a word game that she played with her father into software.

The result: Professor Wordington’s Spellatorium, an iPhone app. Opportunities for innovation came early for Kate when as a freshman she began working on a Boeing research project that focused on development of a navigation system for unmanned aerial vehicles (UAVs), which resulted in a patent.

Or perhaps you have seen our graduate student Jon Moeller in the Best Buy commercial recognizing college students for innovation. Jon proudly proclaims that he is a Texas A&M student and describes ZeroTouch, the most responsive and cost-effective, multifinger sensor available for television-sized displays. He developed the technology as an undergraduate student in computer science. Significant worldwide attention followed and he continues to work on the project through our graduate program.

Kate and Jon are just two examples of how our research programs are enhanced when we encourage our undergraduate students to identify innovative solutions to technical challenges. Given an environment that supports and encourages inquiry, our next generation of engineers will be well prepared to address the complex global challenges of tomorrow.

In this magazine, we feature a small sampling of the research that we are conducting at Texas A&M. Although faculty members are the primary focus in these articles, many of these projects involve students at all academic levels. I hope you enjoy this publication and are inspired by the extraordinary creativity of our students and faculty.

And on it goes.

“This has lots of good benefits,” he says. “You see self-organized systems. You see serendipitous discovery of new information and new uses of these systems beyond what the systems designers had ever imagined. You see communities form. There are all these exciting possibilities that happen when you let people collaborate.”

Now he wants to know whether these systems can be mined to find interesting or useful information to empower decision makers.

Caverlee asks, Can collective intelligence be harnessed?

Online gathering places

Crowds are naturally forming, Caverlee says, and the goal of his current research is to find these online crowds and engage them to accomplish tasks.

In 2010, Caverlee received a grant from the Defense Advanced Research Projects Agency (through the agency’s Information Innovation Office) to identify online “hotspots” in realtime social systems, mainly Twitter, where hundreds of millions of messages are posted per day.

Caverlee looks at tremendous numbers of users and tremendous amounts of information, the places people go, the people they talk to and interact with, the content they are interested in, and the connections between them.

Social media—

user-generated content. Texas A&M computer scientist James Caverlee is studying the use of social media to harness collective intelligence to perform tasks, to persuade and change minds, and maybe even to change the world.

As an expert in large-scale networked information systems—such as the World Wide Web, social media and mobile information systems— Caverlee looks at tremendous numbers of users and tremendous amounts of information, the places people go, the people they talk to and interact with, the content they are interested in, and the connections between them.

These large-scale networked information systems are typically open and intentionally designed to encourage participation, Caverlee says.

10

These online gatherings can be driven by natural disasters or by sporting events such as the Super Bowl. How do you find these hotspots in real time when huge numbers of people are posting hundreds of millions of messages? The task required developing algorithms and methods.

“After the Vancouver riots, people started posting photos and video and messages of the riots,” Caverlee says. “So you had this online reflection of current events. Assuming you can mine these large-scale systems and figure out where people are talking about this particular event, can we close the loop and engage with these crowds that are forming in these systems?

“It’s a form of crowdsourcing,” Caverlee says.

“Can crowds of people online work together intelligently, and if so, how?”

Such crowdsourcing would be useful in a disaster, natural or otherwise. When disaster strikes, human impulse is for people on-site to use Facebook and Twitter to post photos and video of the damage, status updates, and

enginee ringmagazine .tam u .e engineeringmagazine .ed du

their locations. Once these online crowds that have formed in response to this particular emergency are detected out of the hundreds of millions of other online activities, the challenge then becomes connecting the crowds to emergency responders.

“If I am an emergency responder with limited resources, I need to know where to send trucks and rescue teams,” he says. “Emergency responders have to make these decisions with limited information in the immediate moments after this disaster has struck. So let’s engage with these detected crowds and know where they are, but also issue them jobs to complete.”

The National Science Foundation has sponsored some of Caverlee’s work in this area. He says that one job, for instance, would be for people to step outside their homes and take photos of the ground or buildings so that structural engineers can assess the safety of structures in the area. Computers can’t do that job, Caverlee says. Real people need to be directed to take better photos, to give better information that can help decision makers know where to send resources.

“In the moment, as this is happening, the big challenge is to detect this crowd, connect them back to the stakeholder—in this case, the emergency responder—and then give them tasks to do to accelerate decision making and reduce response time.”

Crowd quality—in the moment

Alongside this detection and task assignment is assessing the relative quality of a newly formed crowd. A second project, this one funded by the National Science Foundation, aims to assess and monitor the quality of these crowds.

A typical measure of Web quality is Google’s PageRank, or the content of a page or site, the number of clicks on a page, the links around the page, or how people engage with the site.

CNN.com, for example, may be a reputable

page compared with a blog because CNN has a lot of in-links, a long life on the Web, more site visitors and higher click rates.

“It’s a form of crowdsourcing.

Can crowds of people online work together intelligently, and if so, how?”

But crowds form in real-time systems in response to events, such as a presidential debate, a natural disaster or even just friends talking about a game. The crowd itself may not have a long life span, so a long history to assess the crowd is not available. Instead, researchers have to develop other methods to evaluate relative quality.

“We don’t have history for these people, or accounts,” Caverlee says, “so we have to make assessments in near real time and build models quickly so that we can speed and improve decision making.”

Spam: Not just potted meat

Caverlee says the flip side of these open systems is getting people to participate in, but not abuse, the system.

“Spam has moved out of our e-mail inboxes and into these social systems,” he says, citing the example of Astroturf, a campaign that looks like a grassroots effort that instead uses fake accounts and bots to promote particular candidates or ideas.

Caverlee started his research with Web spammers who tried to manipulate search engine rankings. But spam has evolved, and with the rise of social media such as Facebook, Twitter and Flickr, spammers are now infiltrating and attacking those systems.

In work funded by Google and in collaboration with Steve Webb (then at Georgia Tech and now an independent consultant),

11

Caverlee studied social spammers by deploying social honeypots, a new twist on a classic security reconnaissance trick to attract spammers and then study their tactics and behaviors to reverse engineer a solution to stop them.

The research group ran the social honeypots in MySpace (when MySpace was still popular and active) and in Twitter, engaging in behaviors to attract spammers to them to serve as an early warning system to detect new and emerging behaviors in these social systems.

In Twitter, the group set up accounts that didn’t tweet or tweeted only randomly, and that did not connect with other Twitter users.

“These are passive accounts with no listed interests, that no active users would want to friend—these honeypots are irresistible to spammers,” Caverlee says. “So if one of these accounts tried to be friended, we would turn down the request but then crawl back to mine their profiles and connections. We could build machine-learned models of them based on artifacts of what they’ve left in the system.”

In this war of persuasion, then, researchers want to know how to change people’s minds and views of the world.

Typical spammer behavior is to follow as many other users as possible. Caverlee says an obvious sign of a bot-controlled account is a certain set ratio of friends to followers.

Looking at user history showed that as soon as an upper threshold was reached, the botcontrolled account would immediately dump hundreds of followers to maintain the set ratio. Having many links per tweet is another red flag that a user is a bot-controlled account.

With 60 Twitter honeypots, the team recorded 36,000 spammers in seven months. By modeling the behavior, the team could detect the spam accounts eight to 10 days before Twitter’s own spam detectors did.

Weapons of mass persuasion

The group noticed not only automated spam but also lots of coordinated spam, more like

campaigns. The team found multiple accounts with similar talking points, and more subtle, sophisticated spam campaigns instead of brute-force spam that’s easier to identify.

So the team’s current work, funded through the U.S. Air Force Office of Scientific Research in spring 2012, is looking at propaganda and strategic manipulation in these large networked social systems.

“The social Web and social media have essentially become weapons of mass persuasion,” he says. “You have large numbers of people interacting with each other, so you see not only spam but political campaigns involved in this. You see evidence of governments and hate groups engaging in this.”

In this war of persuasion, then, researchers want to know how to change people’s minds and views of the world.

“We know that this is happening already, but we as researchers don’t have a very good handle on what’s going on, only anecdotal evidence,” he says.

So Caverlee is now trying to detect persuasion at the scale of these large systems, finding these talking points and tracking their evolution. Coupled with that is building mathematical models that can explain this behavior.

“Anecdotally, there’s this idea of tipping points, where things go viral,” he says. “Once we detect these campaigns, can we rewind the tape and build models? Can we find out if it’s the content of the message, or the topology of the social network, or is it key influencers or is it that the message reached a certain kind of inertia, a certain mass of people?”

This all goes back to the idea of these open systems, Caverlee says.

“Anyone can engage, anyone can promote their messages, so it all becomes a war of ideas.

Because I’m a computer scientist, I’m trying to build computational methods for detecting and mining these campaigns, for modeling their evolution, for determining how to stop a campaign or determine the factors that make a campaign go global, and understanding the factors that influence all of this.” O

Energy Improvingreliabilityandefficiency of the electric power grid As energy demand and the power grid’s dependence on renewable generation increase, so does the demand for more reliable power delivery—and the need to improve how we produce and use energy. A professor in the Department of Electrical and Computer Engineering at Texas A&M University is working on one solution that will change how electricity is delivered from suppliers to consumers.

13

The RATC solution will help prevent future power outages, which account for roughly $80 billion in losses each year for U.S. businesses and consumers.

Minimizing the grid’s response time to expensive interruptions will also make integrating intermittent renewable energy sources into the grid easier.

Mladen Kezunovic, the Eugene E. Webb Professor, and his team received a $4.9 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) for their research project, Robust Adaptive Topology Control (RATC).

Their grant is part of $156 million that ARPA-E awarded to 60 leading-edge research projects to dramatically improve how the U.S. produces and uses energy. The new ARPA-E selections focus on accelerating innovations in clean technology while increasing U.S. competitiveness in rare-earth alternatives and 14

breakthroughs in biofuels, thermal storage, grid controls and solar-powered electronics.

The electric grid is subject to interruption from cascading faults caused by extreme operating conditions (such as overloads and energy transfer congestion) and malicious external attacks. The grid can also experience intermittent electricity generation from renewable energy sources, including wind and solar power. For instance, when favorable winds cease to blow, energy from wind power decreases and conventional sources of energy must make up the difference. engi nee ri ngmagazi ne .tam u .e du engineeringmagazine .ed u

The grid’s susceptibility to such interruptions means that research into more efficient power delivery is especially important, Kezunovic says. He also directs the Smart Grid Center at the Texas A&M Engineering Experiment Station (TEES).

The researchers are using a method called topology control—that is, reconfiguring the power system—to improve system operations and manage disruptions within the electric grid.

The RATC solution will be capable of detecting, classifying and responding to grid disturbances by reconfiguring the grid to maintain economically efficient operations while also guaranteeing reliability. This approach would help prevent future power outages, which account for roughly $80 billion in losses each year for U.S. businesses and consumers.

Minimizing the grid’s response time to expensive interruptions will also make integrating intermittent renewable energy sources into the grid easier.

“The new concept will reduce the time to correctly detect, classify and characterize the contingencies and respond to mitigate problems in the power grid.”

“The new concept will reduce the time to correctly detect, classify and characterize the contingencies and respond to mitigate problems in the power grid,” says Kezunovic, who is a fellow of the Institute for Electrical and Electronics Engineers. “The concept uses a new control strategy. The online problem detection and classification will use advanced data analytics. A decision-making, topology-switching control strategy will define real-time actions for mitigating the grid problems under a variety of undesirable operating conditions.”

The new adaptive controls will help avoid costs from the consequences of blackouts, making the power grid more reliable and resilient.

“Basically, it’s a new way to control the grid to mitigate contingencies,” Kezunovic says.

“The control is through optimization software and does not require costly specialized controllers.”

The new adaptive controls will help avoid costs from the consequences of blackouts, making the power grid more reliable and resilient.

The RATC team includes researchers from Texas A&M; TEES; the University of California, Berkeley; Arizona State University; Lawrence Livermore National Laboratory; Oak Ridge National Laboratory; the Tennessee Valley Authority; the Grid Protection Alliance; and Applied Communication Sciences. The RATC team focuses on several different areas. Kezunovic, the principal investigator, works on the disturbance detection and RATC implementation strategy.

“My part is related to making sure the RATC control strategy is implementable since my group is checking feasibility and offering solutions to harden the control system,” he says.

“There are multiple partners on the project, each with a role to look into specific aspects of the solution.”

And once the three-year project is complete, Kezunovic says, he hopes their research will play a critical role in the future of the U.S. electric grid and how it produces and uses energy.

“As the results are obtained and verified using field data, we still have a huge task in front of us to make the industry aware of the new solution and help the transition of our solution into the product line,” he says. “We are working with the ARPA-E team and TEES Texas Center for Applied Technology on developing the technology-to-market strategy for making the solution widely available for the industry to use.” O

STOPPING A SILENT KILLER Destroying HIV before the virus infects cells

Since its discovery in 1981, AIDS has killed more than

25 million people worldwide. The human immunodeficiency virus, or HIV, causes AIDS, and the World Health Organization considers HIV infection a pandemic. About 0.6 percent of the global population lives with HIV, including an estimated 22.5 million people in sub-Saharan Africa.

But now, a powerful topical preventive for HIV could soon be a step closer to clinical trials, thanks to a newly discovered molecular compound that dissolves the virus on contact.

16

engineeringmagazine enginee ringmagazine .tam u .e .ed du

Researchers at Texas A&M University and the Scripps Research Institute have demonstrated the ability of the synthetic compound known as PD 404,182 to break apart the AIDScausing virus before it can infect cells. The discovery was made by Zhilei Chen, assistant professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M, and her team of researchers. Their findings appeared in the November 2011 online edition of Antimicrobial Agents and Chemotherapy 56(2): 672-681, a journal of the American Society for Microbiology.

“This is a virucidal small-molecule compound, meaning that it has the ability to kill a virus; in this case, that virus is HIV,” Chen says.

“Basically, it acts by breaking the virus open.

We found that when HIV comes in contact with this compound, the virus breaks open and loses its genetic material. In a sense, the virus ‘dissolves,’ and its RNA becomes exposed. Since RNA is pretty unstable, once it is exposed it’s gone very quickly, and the virus is rendered noninfectious.”

The compound quickly rips open the virus before it can inject its genetic material into a human cell. What’s more—and perhaps even more important—the compound, Chen explains, achieves this by acting on something other than the viral envelope protein. This means that the virus can’t alter its proteins to bolster its resistance—something that’s made HIV notoriously difficult to treat.

“We believe this compound is not working on the viral protein of the viruses but on something else common in all the viruses on which we tested it—some cellular material common in these viruses,” Chen notes. “Because this compound is acting on a component that is not encoded by the virus, it will be difficult for the virus to evolve resistance against this compound.”

Although not a cure for HIV, the compound shows significant potential for use as a preventive, specifically in the form of a topical gel that could be applied in the vaginal canal, Chen explains.

17

“This is a virucidal small-molecule compound,meaning that it has the ability to kill a virus; in this case, that virus is HIV.”

“We conducted a number of tests to demonstrate that this compound remains active in vaginal fluid and is not rendered ineffective,” Chen says. “In the form of a vaginal gel, the compound would serve as a barrier, acting almost instantaneously to destroy the virus before it could infect a cell, thereby preventing HIV transmission from one person to another.”

Surprisingly, Chen says she and her team did not set out to discover an HIV preventive. Instead, they were screening molecules for use in potential drug therapies targeting hepatitis C virus, which causes the dangerous and often fatal liver disease. Using a screening system that Chen developed, the team

screened thousands of molecular compounds, in search of those that could block aspects of the HCV life cycle.

During the screenings, the team made an interesting discovery: Not only was PD 404,182 an HCV inhibitor, it also worked on lentiviruses (the group’s negative control in its experimental procedures). Intrigued by that finding, Chen then tested PD 404,182 on HIV, also a lentivirus, and found the compound even more effective.

“We believe PD 404,182 acts through a unique and important mechanism,” Chen notes.

“Most of the known virucidal compounds interact with the virus membrane, but our engineeringmagazine enginee ringmagazine .tam u .e .ed du

The molecular compound discovered by Assistant Professor Zhilei Chen could help limit the spread of HIV when used in a preventive topical gel that dissolves the virus on contact.

compound does not appear to interact with the virus membrane. Instead, it bypasses interaction with the membrane and still compromises the structural integrity of the virus.”

The compound’s ability to avoid interaction with the virus membrane is important because human cells have similar membranes, Chen notes. If the compound were to disrupt the structure of the virus membrane, it could also disrupt and ultimately kill human cells. PD 404,182 doesn’t interact with these membranes and is therefore a more attractive option for clinical treatment, Chen says.

As with any potential pharmaceutical, several key steps are still needed before it winds up on drugstore shelves. In addition to several rounds of animal studies to ensure that the compound is safe for humans, further collaborations with chemists are needed to continue to improve the efficiency of the compound.

Chen says she also plans to further explore precisely how PD 404,182 breaks apart HIV. This work is a collaboration between Chen’s team, consisting of graduate students Ana Maria Chamoun and Rudo Simeon; postdoctoral associate Karuppiah Chockalingam; and Professor Philippe Gallay’s team at the Scripps Research Institute.

Estimating the weight of helicopters during flight for military and medevac operations

21

Rogers and his students are working to create an avionics package that will provide precise weight and mass center information to the pilot in real time.

Helicopters

offer versatility and ease of access that other modes of transportation cannot. From military operations to use in lifesaving medical situations to transporting VIPs, more than 45,000 helicopters are in operation worldwide, making them as common a sight in the skies as airplanes.

By measuring the aircraft responses to the pilot’s control inputs, the onboard software package will estimate weight and mass center by using advanced computational methods.

But for helicopters—unlike airplanes—the weight and center of mass can change drastically during flight. In a battle situation, cargo or troops may enter or leave the aircraft rapidly. The pilot may not know precisely how the helicopter’s weight has changed, and he or she has little time to figure it out.

“Currently there is a person whose job it is to estimate the weight of items coming on and off the aircraft,” says Texas A&M University aerospace engineering professor Jonathan Rogers. “They are very conservative because they have to be. A pilot’s precise knowledge of

22

how much the helicopter weighs would benefit him greatly.

“Right now, with these estimates, the pilot doesn’t really know [the exact weight and mass center]. So when it comes to questions like, ‘Can I operate in certain conditions?’ and ‘Can I hover at a certain altitude?’ it is probably somewhat of a guessing game.”

To remedy this, Rogers and his students in the Helicopter and Unmanned Systems Laboratory (HUSL) are working to create an avionics package that will provide precise weight and mass center information to the pilot in real time. By measuring the aircraft responses to the pilot’s control inputs, the onboard software package will estimate weight and mass center by using advanced computational methods.

“This will provide the information he or she needs to make better decisions. What we are going to do is take these helicopters and drop weights off them when they are flying and see if we can filter the sensor data and the control inputs,” Rogers says. “Using Kalman filters [an algorithm using a series of measurements observed over time] and potentially more advanced methods, we will attempt to, in real time, estimate the weight change that has taken place.”

Once that is determined, the avionics package would give the pilot an estimate of how much the helicopter weighs and where the mass center is located.

engineeringmagazine .tam u .ed u

Aerospace engineering graduate student Nate Miller is designing autonomous helicopter flight control laws to enable a wide variety of UAV research projects at the Helicopter and Unmanned Systems Lab.

Early attempts at solving the engineering problem Although Rogers’ current project is new to Texas A&M, he says it has been tried in various simulations and it has proven effective.

When Rogers was conducting his postdoctoral research two years ago at the Georgia Institute of Technology, his adviser at the time proposed this system to a consortium of helicopter companies and to NASA, which partakes in a lot of rotorcraft research. But they were less than enthusiastic.

Because of the conditions helicopters fly in as well as the loads placed on them, certain parts require replacement and repair more often than others.

Other benefits

“They said you can never make it work in practice,” Rogers says. “He found out later that at least two of the helicopter companies were pursuing those initiatives internally.”

The operating costs for helicopters are much higher than those of fixed-wing aircraft, such as airplanes. Because of the conditions helicopters fly in as well as the loads placed on them, certain parts require replacement and repair more often than others.

Being spurned didn’t cause them to shut down shop. Instead, it only motivated them even more, and Rogers has brought that passion to succeed with him to Texas A&M and has instilled it in his students.

Rogers contends that his research will help in the area of maintenance as well. Having exact weights, rather than just estimates, means that certain parts of the vehicle would not need to be replaced as often.

“Our attitude was, ‘Let’s do this and let’s make it work and show everybody that it can work in practice,’” Rogers says. “That is the beauty of having these helicopter vehicles that we have in the HUSL. We can take these ideas that everybody agrees work in simulation and show that they do work in practice.”

“There are certain life-limited parts in a helicopter that, based on how long it has been operated and at what weight it has flown, have to be replaced,” Rogers says. “If we can extend the lifetime of these parts, we can reduce operating costs. That would be one of the huge benefits.” O

Walking Building two-legged robots that can walk—like humans

Science fiction has long promised two-legged, humanlike robots that can walk among us, but those are not yet reality. Self-described sci-fi buff Aaron Ames, assistant professor in the Department of Mechanical Engineering and the Department of Electrical and Computer Engineering, is building the robots himself.

25

Q&A

The goal of this research laboratory is trying to get humanlike, robotic walking.

What does that mean?

the potential to surpass wheeled robots, but walking robots require a lot of sophistication that’s just not yet present.

Humans are incredibly efficient at negotiating diverse terrain, and robots don’t have that capacity yet, especially two-legged robots.

There are a million different robots being built all over the world, but they all walk only on flat ground with really stiff gaits.

So how are you studying human walking? How do you find that essential information about human movement that you are applying to robots?

We are trying to discover what humans do when they walk, to get that essential information needed to get efficient robotic walking. And not only efficient but also extensible, so we can eventually do things such as climb stairs.

In the end, what we want is a robot that can go into a disaster area—say, a rubble-strewn area—and get through there in a way that wheeled robots can’t. Walking robots have 26

AMBER 2.0, the second robot Ames and students have built in the A&M Bipedal Experimental Robotics (AMBER) Lab, exhibits more advanced walking behaviors than its predecessor, AMBER 1.0.

Motion capture is actually how all this got started. In fact, it got started about two years ago with an experiment at Berkeley where we did some motion capture of human walking.

We’re really coming up with a formal description of walking. By looking at the data, we found that humans do very interesting things when they walk, and in fact humans display this very simple behavior in the end. After some data analysis, we found that humans basically act like mass-spring damper systems, the simplest example of a mechanical system.

Despite all this complexity going on, humans fall into this simple behavior.

engineeringmagazine .tam u .ed u

That’s a good thing, because there’s a sort of hierarchical control in humans where, when we learn to do something very well, we basically move all that processing down to pattern generators in our spinal cords. So we don’t really need our brains to walk, which is why we can still walk if we’re texting or reading or doing something else. You don’t need vision or anything. What do you need all that cognition for? You need it to switch between different behaviors. If you don’t see steps coming and you take a step off a step, you have that surprised feeling of falling when, suddenly, your body realizes it’s not doing what it’s meant to be doing.

So we have to look at human data. But robots are so finicky, so if we took that human data and just put it into these robotic legs, it wouldn’t work because these legs aren’t in humanlike proportions. The robot legs would maybe move through the oscillations in the right way, but the robot wouldn’t actually be able to sustain walking. So we look to human data and process that data to extract the essential information about walking. Once we have that information, we encode that in our robots.

All our robots use to get this walking is human data. That’s the only input to the system. So if you want a robot to do any human behavior, all you have to do is watch a human do it, apply this algorithm to get that, and the robot does it. And we’ve done this with stair climbing now in simulation, going up and down stairs, walking on flat ground, stopping, and we’re going to start doing things like running and turning. We have started to build up this template of behaviors.

So that’s where humans play a role; they’re directly involved in this.

What kinds of robots are you using in your lab?

We’ve built our own robots here, really just pairs of legs. What’s interesting about our first robot, AMBER 1.0 (named for our lab, the A&M Bipedal Experimental Robotics Lab), is that the motor being used to drive this robot is about the size of a C battery. Imagine how efficient your walk would have to be if your muscles were the size of a battery. Rather than overdesign this thing with huge motors, we’re trying to get very efficient walking. That makes things tougher because when there are uneven surfaces, or when things don’t happen exactly the way you think they will, then the robot will fall.

And because it’s not the most human-looking rig in the world, we also bought a NAO robot. This is a total humanoid robot, and we’re applying the same kind of methods on this to try to achieve walking. It’s a little less fun in some ways—it’s a closed platform, and we can’t build it from scratch because we don’t know every component in it—but it is an easy way to try out some things really quickly on many more degrees of freedom.

I have some research collaborations with NASA in Houston; they’re actually building a humanoid robot, an actual full-fledged biped. We will have to come in without having designed or built the robot and apply all our methods to it, so playing with this NAO platform that was designed by somebody else gives us a feeling as to how we could do that with NASA’s robot.

If you want a robot to do any human behavior, all you have to do is watch a human do it, apply this algorithm to get that, and the robot does it. So that’s where humans play a role; they’re directly involved in this.

You mentioned collaborating with NASA. Is space travel or exploration a possible application for walking robots?

Yes! A very cool possible application for bipedal robots is space exploration. I don’t think we’re going back to Mars anytime soon as humans, but we are sending robots there.

What ended up making Spirit and Opportunity and other space robots and rovers fail is that they can’t get around very well. They got stuck in the soil and had trouble moving around.

The Curiosity rover that landed on Mars in August promises to have more mobility than previous rovers, but it’s fundamentally limited because it is wheeled.

Legs have the potential to get the scientists to the places where they can make the discoveries they really want to make—going through the polar ice caps or going down into craters.

There’s a huge potential there.

27

The researchers evaluate AMBER 1.0’s motion on a computer (left) while the robotic legs “walk” on a treadmill (right) .

So the advantage of robots on legs over wheels is clear. What’s the advantage of having robots on two legs instead of four (or even more)?

Bipeds do allow you to go places even the quadrupeds can’t. But there’s a more important reason than that: If we really wanted this technology in terms of just robots, maybe four legs would be okay and four-leg robots would be built. But understanding human motion, human-leg motion, means that we can apply these ideas to places where humans and robots interact.

So another big application area that we’re looking at is prosthetic design. If you understand exactly how a human walks, and you can realize that in robotic motion in a very precise fashion, then you can imagine building prosthetic devices that allow humans to do all those things. Especially for double amputees, let’s say, who have huge mobility issues. Even with the current state of prosthetics, double amputees have to use canes to get around, and it’s very difficult.

28

It’s amazing because double amputees really want to try out these things because it’s so hard for them to do anything in their everyday lives. So we can take care of two birds with one stone: We’re building robots that can do amazing things, and that gives us the potential to build prosthetic devices such as exoskeletons, rehabilitation devices and orthotics—there’s a whole wealth of applications if you understand how bipeds locomote.

So these robotic legs walking in place on a treadmill are the simplest model to understand before we move to robotic legs that actually can move forward. The elemental unit here is human data, so it is not surprising that this movement is fairly human looking. We are trying to merge human data, and that actually feeds into the prosthetics and everything else because you can look at the behavior of a healthy human leg and try to mimic that behavior directly through these formal methods.

engineeringmagazine enginee ringmagazine.tam .tamu u.ed .e du u

So what brought you to robots?

Science fiction. I’m a huge sci-fi buff.

I probably have thousands of sci-fi books on my shelves, and I’ve just been fascinated by making robots that can do what humans do. It’s funny: Even in my application to graduate school, I said I wanted to work on bipedal robots. And then in graduate school, I studied formal math and theory so that I was finally able to take all those tools and come back to robotic walking again the way I really wanted to do it.

And what I always wanted to do was really understand it. I don’t want to just make it walk. I want to know exactly why it’s walking. What are those fundamental mechanisms that humans use?

And the amazing thing is that humans do something that is incredibly simple.

We discovered recently that humans basically act like masses and springs.

That’s what we do. Despite all these complexities that we have, when we settle into something very simple, we display this elementary behavior. And it’s that understanding that allows us to understand this robotic walking.

We can use that and basically make the robot do the same thing, and turn it into thousands of lines of code, and then the robot starts to walk. You can see it on the knee behavior of these legs: There’s a vibration after the foot strikes the ground. The “knee” is absorbing that impact that occurs with every step.

Walking really is this delicate balance, too—being on the verge of being unstable. That’s what makes it really hard. Walking can be described as controlled falling. Humans sort of throw their legs forward and just know that they’re going to catch themselves.

That’s what makes it so difficult to do on robots.

We’re building robots that can do amazing things, and that gives us the potential to build prosthetic devices such as exoskeletons, rehabilitation devices, and orthotics— there’s a whole wealth of applications if you understand how bipeds locomote.

What are some of the hurdles to traversing flat ground or going over rocky surfaces?

Where is your research going next?

Our first goal is to start to get other behaviors like walking up and down stairs. There’s a difference between steady-state human behaviors—things that we do on a regular basis, such as climbing stairs— and walking over rocks.

AMBER 2.0, our second robot, walks off the treadmill and does more interesting walking behaviors, moving forward as it walks in a circle. We’ll determine how to extrapolate all this knowledge to get to things like stepping over stones and walking on uneven terrain. And then you need a visual processing system in the robot.

So there’s a whole process going on here. But eventually, I think all that will allow us to understand exactly how to navigate any environment by essentially extrapolating between all these behaviors.

Yes, there are huge challenges, but extrapolation is what we’re counting on. Once we understand all these basic things, then we can potentially look at a human going through a rubble-strewn area and how a human handles an uneven area, and then get the robot to operate the same way.

And then the robots will be able to switch between all these behaviors, and suddenly you’re much closer to having robots able to do these things that science fiction promised me when I was growing up. That’s the goal. And as far as I know, no other methods used today really have that extensibility. I think it’s fair to say that this is the first one that’s really able to do that. O

Zhu–ming around the

Globe 30

engineeringmagazine .tam u .ed u

Ecu New Indo Aus Colo Chin Mal Tha Indo Alas Los San Hou

By Kara Bounds Socol

Ding Zhu knew well before leaving home that she wouldn’t be the most beloved presenter on the Society of Petroleum Engineers (SPE) lecture circuit. But she would generate some of the most controversial conversation.

31

Zhu

, a Texas A&M associate professor and the W.D. Von Gonten Faculty Fellow in Petroleum Engineering, was one of more than 100 hopefuls for an SPE distinguished lecturer slot. After an SPE panel chose her abstract on inflow control devices (ICDs) for consideration, Zhu went through an intensive interview process and was one of the 30 selected to give lectures to SPE groups worldwide. She recently completed her 22-stop tour.

During her eight years at Texas A&M, Zhu has focused her research on using modern technology to increase oil and gas production.

Zhu’s audiences varied from seven people in Hobbs, N.M., to some 250 in Quito, the capital of Ecuador.

Although some stops were somewhat close to home, others were as far away as Melbourne, Australia, and as remote as Balikpapan, Indonesia.

As Zhu has spoken to SPE groups around the globe, she’s found that hostility toward the subject of her presentation is a worldwide phenomenon.

“Some people shut down when they hear the letters ‘ICD,’” Zhu says of the device’s detractors. “They just think you’re trying to sell them something that doesn’t work.

They don’t actually look at the principle of how it works.”

But for the most part, audience members were willing to hear what she had to say.

“In the majority of the cities, there was hot discussion,” Zhu says. “But they thanked me for the discussion at the end and said they really understood ICDs more.”

ICDs: inflow control devices An ICD is designed to maximize oil recovery in long horizontal wells by controlling the flow rate of oil from the reservoir to the well.

PeopleneedtounderstandwhenanICDwillhelp.

So why the fuss over ICDs?

Some producers see an ICD as a magical guarantee for increased production.

Others will say they’re extremely expensive, difficult to install and maintain, and fail to encourage oil flow. In short, when they invested in the device, they felt like they were duped.

On both counts, Zhu disagrees.

32

Understanding ICDs

An ICD is an intelligent completion hardware designed to maximize oil recovery in long horizontal wells. Oil flowing too quickly or too slowly from the reservoir to the well has a negative impact on recovery. An ICD regulates that flow rate.

The ICD also adds to the producing life of the well by preventing “coning”—the penetration of water or gas into the oil column during uncontrolled production.

engineeringmagazine .tam u .ed u

.

But for ICDs to work, Zhu says, they must be used only under the right conditions.

These include either a very long horizontal well with a great deal of oil or very thin oil reservoirs with a gas cap on top and a water aquifer underneath. If the well is too short, she explains, the ICD will not perform as promised.

“The catch is for people to understand exactly when you can use an ICD to help you,” she explains.

And she should know. During her eight years at Texas A&M, Zhu has focused her research on using modern technology to increase oil and gas production. This research encompasses techniques to access shale gas and oil, specialized methods required for heavy oil, and improved procedures to access “tight gas”—natural gas reservoirs locked in extremely hard rock.

Zhu has developed several computer software applications for intelligent control of wells—using computer sensors to improve production. Classrooms and oil fields all over the world use PPS, a production engineering software package she developed.

A Promising Future

When Zhu announced her selection as a distinguished lecturer, a friend warned that by presenting her abstract, she’d be making enemies of the major oil companies. But Zhu takes a different approach: “If I’m wrong, I’d like to hear why you think I’m wrong.”

On the SPE tour, she got her wish. But instead of being offended by detractors, she found that the discussions her presentations started were one of the things she liked most about the lecture tour. She also says she enjoyed getting to know SPE members from around the globe and was encouraged by the enthusiasm of many of the younger members.

In Balikpapan, for instance, most attendees had been in the oil industry for five years or less.

“They really want to connect with SPE,” Zhu says. “We had a lot of discussion about how young people in the industry should look at the future.”

She had a similar experience in Colombia, where about 30 students traveled by bus to a remote location to attend the SPE event and then stayed two hours after her presentation.

“Colombian young people are very aggressive, in a good way,” Zhu says. “They love their society, they’re technically involved, they want to help their people. When I look at them, I think their country is going to have a good future because they love it so much.”

She felt similar feelings of promise when speaking to groups in other remote corners of the globe.

“You hear people speaking all kinds of languages, and they’re all looking for something better—not just for themselves but for their whole society,” Zhu says. “I’d think, ‘I’m so proud to be with this group of people.’”

A Big Milestone

The travel schedule of an SPE distinguished lecturer is grueling enough, but because of her teaching schedule, Zhu had to cram a year’s worth of stops into six months.

Her sightseeing opportunities, then, were extremely limited.

“You hear people speaking all kinds of languages, and they’re all looking for something better—not just for themselves but for their whole society. I’d think, ‘I’m so proud to be with this group of people.’”

During the Asian portion of her tour, Zhu visited China, Malaysia, Thailand, Indonesia and Australia in two and a half weeks. Even worse was hitting Alaska, Los Angeles, San Francisco and Houston in four days.

“There were times when I got up, went to the talk, then went directly to the airport,” she says.

For her presentation in London, for instance, she arrived at the airport at 1 p.m., attended the SPE event from 5:30 p.m. to 9:30 p.m., and then took the first flight back the following morning to teach her class at Texas A&M. Constant travel, sleep deprivation, time away from family—these were all downsides to Zhu’s six-month tour. Ultimately, though, the people she met and the honor of being singled out by SPE outweighed the frustrations.

“When you look back,” she says, “you see that it’s a big milestone in anyone’s career.” O

By Lesley Kriewald

Each year in the United States, congestive heart failure affects more than 5 million people, and more than 500,000 new cases are diagnosed.

On top of that, about 300,000 patients per year decompensate, or experience a loss of function in their hearts, to the point of needing a heart transplant. Unfortunately, only about 3,000 hearts are typically available on the national transplant list. Only the sickest, most desperate patients make the cut.

John Criscione says he thinks he can help the rest.

“Everyone has their own heart,” says Criscione, associate professor in the Department of Biomedical Engineering.

“We want to get theirs to work right.”

MECHANICS Restoring proper motion to save heart muscle

35

Correcting motion

Restoring proper motion

“The heart never stops moving,” Criscione says. “So if the mechanics are different than what happens in a healthy heart, then that change in motion can kill the muscle. So motion is the most important factor in keeping heart muscle alive.”

“To test that, you’d have to be able to change the motion of the heart,” Criscione says.

“Therapy could be beneficial to patients, but we need devices to help correct that bad motion.”

The endeavor started with the idea that motion was a key factor in heart growth.

Criscione is an expert in cardiac mechanics, the study of force and motion in the heart. In all muscle, he says, the type of force is tension, but motion differs in different types of muscle. In skeletal muscle, motion can consist of isometric contraction or elongation. In heart muscle, though, contraction is the only option: Other types of motion lead to cardiac muscle death.

“The heart never stops moving, so if the mechanics are different than what happens in a healthy heart, then that change in motion can kill the muscle. So motion is the most important factor in keeping heart muscle alive.”

“The heart always does positive work,” Criscione says, “taking blood and ejecting it against pressure. That contraction is the key motion for the heart.”

Heart disease, he says, is characterized by bad motion. With the rise of AED (automated external defibrillator) devices, aspirin therapy and education, more people are surviving heart attacks than ever. But the blockage in the coronary artery that caused the heart attack actually changes the motion of the heart, so surviving a heart attack is the number-one factor in end-stage heart failure.

“Imagine,” Criscione says, “if you lost the use of your quadriceps, what would your gait look like?”

Dr. John C. Criscione

Biomedical Engineering Associate Professor 979.845.5428 jccriscione@tamu.edu

36

Arrhythmias, or irregular heartbeats, can also lead to blockages and movement changes.

Drugs can help restore proper motion because they lower the amount of work the heart needs to do. But, Criscione says, this approach doesn’t correct bad motion and only delays heart failure.

Criscione says he wonders whether that bad motion in the heart is not a symptom of disease but rather a source.

Criscione says that rehabilitating the heart after a heart attack might be possible—a kind of cardiac physical therapy.

“When something goes wrong with joints and muscles, we need mechanics to get back into shape,” Criscione says. “After a car accident or surgery, physical therapy can help repair the joint to become more functional. I think we can do the same for the heart.”

Criscione says such cardiac physical therapy would change the load on the heart, thereby changing the heart’s abnormal mechanics to guide good heart growth and operation.

To that end, Criscione has developed a device that fits around the heart. Pumping air into the chamber around the heart squeezes the heart and pushes blood out. Releasing the air allows the heart to expand and fill with blood.

Implanted after all other therapies have failed and patients are incapacitated from end-stage heart failure, the device could restore proper motion to the heart. Criscione’s invention modulates the growth of the heart but doesn’t replace the heart or its action.

And unlike current devices on the market, Criscione’s heart-assist device does not come in contact with blood, which means less risk of infection or stroke.

“Blood is the most aggressive organ in the body,” Criscione says. “Blood is very reactive because it needs to be.”

Learning process

In 2004, Criscione founded CorInnova Inc., a biomedical device startup focused on developing mechanisms to help with congestive heart failure. His company received $500,000 from the Texas Emerging Technology Fund in 2006 to commercialize the heart therapy device, allowing the company to grow and develop more.

engineeringmagazine .tam u .ed u

This experience has translated to the classroom, where Criscione teaches his students about regulatory affairs, design and development, preclinical testing, and clinical trials—things students will need to know to succeed in the biomedical device industry.

The technology work is complete in terms of proof of concept. Still to come are manufacturing, testing and clinical trials.

“The idea is a critical step,” he says, “but it’s just a baby step in the process.”

As far as getting investors in CorInnova, Criscione says potential investors look at the commitment and experience of the people behind the idea first, and the idea itself second: The best idea with the wrong people won’t succeed because making mistakes is too easy in a highly complex and regulated marketplace such as health care. But, he says, even a mediocre idea can succeed if the people driving it are motivated and have succeeded in prior endeavors. Such individuals already know the potential pitfalls and have successful approaches to shepherd technologies through preclinical testing and premarket approval by the U.S. Food and Drug Administration.

In fact, the process thus far has been quite an education in commercialization, Criscione says.

“The risk in medical devices is the clinical trial and getting FDA approval because these are expensive, uncertain barriers to market that have to be completed before any revenue can be generated,” he says. “If it succeeds in clinical trials, then the market will likely adopt it.

“In other technology areas like consumer electronics, there is no such barrier to market release for

new products. The risk there is primarily related to market adoption.”

This experience has translated to the classroom, where Criscione teaches his students about regulatory affairs, design and development, preclinical testing, and clinical trials—things students will need to know to succeed in the biomedical device industry.

“We’ve done a lot as a medical community to save people, which is good, but now I think we can restore proper motion so people will live even longer.”

Meanwhile, the work continues. The next step is design manufacturing and preclinical testing, and to complete this preclinical work and begin clinical trials—which can last up to two years themselves—could take three years. All told, it may be another five years until the device is ready for market.

That may sound like an eternity, but that’s typical for biomedical devices, Criscione says, which usually take 10 to 15 years to come to market.

“We’ve done a lot as a medical community to save people, which is good,” Criscione says. “But now more people are surviving with damaged heart muscle, and I think we can restore proper motion so people will live even longer.” O

ASEE President Walt Buchanan: EducationLeader,LifelongLearner The man leading the nation’s most influential engineering education organization is perfect for the job. His insatiable love of learning has led him to his newest academic endeavor, taking the helm of the American Society for Engineering Education.

By Kara Bounds Socol When Walter Buchanan attended his first American Society for Engineering Education (ASEE) annual conference in 1985, he was a junior faculty member at Indiana University– Purdue University Indianapolis, and a Texas A&M dean was soon to be ASEE president.

The ASEE annual conference returns to Atlanta in June 2013, and once again a Texas A&M professor will be president. This time, Buchanan himself will fill that position.

“Never could I imagine that the next time I went to the conference in Atlanta, I’d be president,” says Buchanan, head of Texas A&M’s Department of Engineering Technology and Industrial Distribution.

In its 120-year history, ASEE has elected four Texas A&M faculty members to its presidency.

Only Penn State exceeds that number, with five presidents. Buchanan is only the second society president from the field of engineering technology.

When the Soviet Union launched the world’s first artificial satellite, Sputnik, in 1957, the space race was on. This new era in engineering required a new type of engineer.

Since the 1940s, a basic form of engineering technology had been offered as a two-year technical program. But now the aeronautical industry needed people with the hands-on skills of an engineering technician coupled with the mathematical skills of a traditional engineer. The four-year engineering technology degree thus emerged.

Buchanan is a product of the space race era and knows firsthand how crucial the skills of a four-year engineering technology graduate can be.

Engineering technology graduates apply modern technology to real-world technological problems, Buchanan explains. And students in the partner field of industrial distribution study technological subjects to succeed in manufacturing sales.

Engineering didn’t always interest Buchanan, but mathematics did. At Indiana University, he double-majored in mathematics and Russian and minored in astronomy, physics and German. When he graduated in 1963, the Martin Co. immediately offered him a job as an aerospace engineer. This first job, though, was not the result of the space race, but rather of the Cold War. Perhaps nothing symbolized the fear of nuclear conflict with the Soviet Union more than the 54 Titan II missile sites on alert across the United States. The Titan II could launch in 58 seconds and could deliver a nuclear warhead to targets more than 6,300 miles away.

Engineering technology, Buchanan says, prepares students to be technological problem solvers. The field focuses more on actual application than does traditional engineering, so its graduates are typically the ones closest to the production process. Their jobs often involve using both engineering principles and modern technology to improve production.

Education Leader, As a young engineer, Buchanan did system analysis on the Titan II missile program. But when Martin did not receive a Titan II followup contract, Buchanan moved to the Boeing Co., where an even more exciting project was taking shape: the Saturn V rocket program.

In 1970, Buchanan began working as an audit coordinator for the Indiana State Tax Board by day, and he studied law by night. Three years later, he graduated from law school and worked in administrative law for the Veterans Administration in Indianapolis.

In his job as a systems analyst, Buchanan served as a mathematics liaison between the Saturn V programmers and electrical engineers. In 1969, this rocket would launch the spacecraft that would land men on the moon.

But by then, Buchanan had moved on to his next challenge.

But once again, Buchanan became restless.

So he began taking night courses in engineering, thinking he would go into patent law.

However, he enjoyed engineering so much that he never went back to law and went to work as an electronics engineer for the Naval Avionics Center.

“I didn’t consider it work. I treated it more like a hobby. If you do what you enjoy doing, it’s not work.”

In 1965, the Vietnam War was raging and Buchanan wanted to be on the nuclear engineering side of things. He enlisted in the Navy, eventually serving on an aircraft carrier in the Gulf of Tonkin, his last billet being to serve as its gunnery officer.

As an officer, Buchanan participated in courts martial when soldiers under his command got into trouble. The legal process fascinated him.

Upon returning home, he decided, he would become an attorney.

1993

“I didn’t consider it work,” Buchanan says of his educational pursuits. “I treated it more like a hobby. If you do what you enjoy doing, it’s not work.”

Influencing engineering education

With engineering degrees in hand, Buchanan says he was ready to teach others what real life had taught him.

He’s a member of the Indiana State Bar and is a registered professional engineer in six states.

Lifelong Learner Beginning as an assistant professor at Indiana University–Purdue University Indianapolis, Buchanan moved up the academic ladder, teaching at four more universities before securing the top engineering technology post at Texas A&M in 2005. In June 2012, the J.R. Thompson Endowed Chair took his post as ASEE president.

Focusing on the teaching of engineering and engineering technology, ASEE was founded more than a century ago. Although some engineering faculty members are involved in the organization, Buchanan says, many ASEE members work in engineering technology.

“In engineering technology, the focus is more on teaching than on research,” he says. “Our faculty on the average teach two times as many classes as engineering faculty, but we only do half the amount of research.”

While serving as president, Buchanan will travel extensively for a year, speaking at university conferences around the globe. He says he’d also like to use his influence to help students afford college, particularly through online courses and transfers from two-year to four-year programs.

Also critical, Buchanan says, is to excite elementary and secondary schoolchildren about engineering. He hopes to do so by

But the wait will soon be over. In November, Buchanan will travel to Kazan, Russia, as part of his ASEE duties.

By 1993, Buchanan had earned five degrees: a bachelor’s degree in mathematics and Russian, a law degree, a bachelor’s degree in engineering, a master’s degree in engineering, and a doctoral degree in higher education.

“I never dreamed that when I went to Russia, it would be 20 years after the fall of the Soviet Union and they would be paying me to go there,” he says. O

Now imagine someone outside the burning building or someone back at the military base camp guiding you to safety as if a hand were on your shoulder, steering you in the right direction.

It may sound a bit farfetched, but it might not be as unbelievable as it sounds thanks to the work of Texas A&M University professor Thomas Ferris.

Ferris, an assistant professor in the Department of Industrial and Systems Engineering, is developing a communication system that, using the sense of touch, would prove invaluable in such scenarios.

“We are exploring the sense of touch as a communication channel. We are already familiar with technologies that use this channel in very basic ways, like when we set our cell phone to vibrate.”

“Our research is the next frontier in the area of multimodal communications, meaning communicating with people via multiple different senses, which can be very advantageous for human operators in certain environments,” says Ferris. “In particular, we are exploring the sense of touch as a communication channel. We are already familiar with technologies that use this channel in very basic ways, like when we set our cell phone to vibrate. We then receive haptic or tactile messages communicating that there is an incoming call.”

Taking advantage of the sense of touch

Ferris and his students in the Human Factors and Cognitive Systems Lab are pushing the limits of what can be done with the sense of touch while taking advantage of some of its unique characteristics.

“The sense of touch is really great for giving directions to somebody,” says Ferris. “I can give you navigation instructions orally by saying, ‘Look to your left and take 10 paces.’ I could draw you a map and give it to you. But the most efficient way would be if I could put my hands on your shoulders and essentially push and pull you.

“Using the sense of touch, we can direct people with simple instruction. If you feel a vibration or a push on one side of your body, move in that direction. It is stimulus–response. Very little thought is required in interpreting and acting on the message, so people can react quickly to the message without it demanding too much attention. There are a lot of applications where you need to move somebody as quickly and efficiently as possible.”

To accomplish that goal, Ferris and his students have come up with the CHIAD (Creative Haptic Interaction At a Distance) system. The program supports the ability to essentially tap someone on the shoulder, guide the person in a certain direction, or draw a complex shape on someone’s back—all while standing across the room or even in a different building.

In its early stages, the CHIAD system involves an athletic compression shirt worn by an individual called the “actor.” Vibrating devices on various spots on the shirt allow for the ability to “tap” the actor and move him or her in one direction or the other.

Tactors are small transducers, designed to optimize skin response to vibration. These devices are used to provide communication to replace or supplement audio and visual input, especially under circumstances where audio and visual cues can be missed.

The “tap” is made using a simple and cost-effective Wii remote that is in the hands of an individual called the “director.”

Using the remote, the director simply gestures in the direction the actor should go. The force of the director’s gesture is also mapped to the intensity of the vibration, so the actor can be gently prodded along or can feel the need to move with various degrees of urgency.

“I could essentially gesture as if I’m tapping someone on the shoulder with the Wii remote and the actor would feel that on the shoulder from a distance,” says Ferris. “We can also have the actor return a haptic message with the use of a second system—something natural and intuitive, like a pat on the back, to communicate that the signal was received. The underlying goal is, we want people to be able to interact without thinking too much.”

Easing fears in stressful situations

Allowing such simple interaction, Ferris says, would aid in situations where stress and fear would overcome the person, making clear thinking difficult.

For example, Ferris cites his daily route in getting to his office. Every day he parks in the same spot, enters his building through the same doors and proceeds to his office.

The repetitiveness allows him to basically go through the process without thinking about it.

But add another element such as a fire outside his office, and things could change.

“If there is a fire outside my office door and my life is at stake and I am stressed out about it, that tends to narrow your cognition,” says Ferris. “Even though I know there are numerous routes that I could possibly take to escape the building, it will be difficult for me to think of anything other than the same familiar route I take every day. [In stressful situations] people tend to have a very hard time thinking outside the box or outside of what is very familiar to them.

“The underlying goal is, we want people to be able to interact without thinking too much, especially when their cognition is limited due to high stress levels. That is one of the beautiful things about the sense of touch. We can interact with each other without having to think too much about encoding a message before I send it, or about decoding the message if I am receiving it.”

Military interest

The military can also use Ferris’ system on the battlefield, which according to Ferris could help minimize threats to soldiers’ safety.

CHIAD can also reduce the time for the commander to guide the soldier away from such dangers, and it allows the soldiers to keep their eyes and ears focused on other things of interest.

Ferris says that commanders would have “a vantage point that allows them to see things that a soldier cannot see, as well as additional sources of information about the area. They can see these constantly changing areas of threat and where their objective destination might be. Right now, soldiers receive their coordinates auditorily and then consult their GPS. That takes some time.

“If we can shorten the time it takes for someone to communicate the message as well as the time it takes for someone to receive the message and act on it, then that can be a big

“The underlying goal is, we want people to be able to interact without thinking too much, especially when their cognition is limited due to high stress levels.” difference in situations like this. If somebody could just gesture and say, ‘Follow my cues,’ and people could respond that quickly, it would be a big benefit.”

Having seen the benefits of haptic display systems, the military has begun testing several different prototypes. Their systems, however, primarily use a belt to relay the vibrations, which limits the expressiveness of the system.

It also adds more to a part of the soldier’s uniform that already holds several other items.

These systems also tend to be automatically linked to other equipment such as a GPS and therefore don’t support the type of person-toperson interaction that the CHIAD system was designed to support.

“They see similar advantages to the sense of touch,” Ferris says. “What we can add is having the communication aspect, and also ours is not limited to one location on the body.

CHIAD can be reconfigured fairly quickly to present vibrations anywhere on the torso, and other garments can be incorporated to present signals to other locations if the application requires it.” O

profession.

According to the American Society for Engineering Education, women accounted for 18 percent of engineering bachelor’s degrees and 22 percent of master’s and doctoral degrees in 2011. And in U.S. universities, women make up 13.8 percent of tenured and tenure-track faculty.

Kathy Banks, vice chancellor and dean of engineering, says that she plans to address this gender disparity during her leadership of the Texas A&M Engineering Program, which includes the university’s branch campus in Doha, Qatar.

“She’s done so much for women in Qatar,” Al Bishri says. “Now I want to contribute to Qatar and give back to the community that helped me study engineering.”

“It’s unfortunate,” she says, “that young girls often are not encouraged to enter the engineering profession. Anyone who has passion for creativity and learning and discovery, anyone who wants to change the world for the better, should consider a career in engineering.”

Qatar’s leaders share this viewpoint and recognize that the country must encourage all talented young people, male and female, to pursue technical careers. As Ibrahim Ibrahim, secretary general for the General Secretariat for Development Planning and economic adviser to His Highness the Emir, Sheikh Hamad bin Khalifa Al-Thani, says, “Demand for engineers is high, and women are integral in filling that need.”

To encourage young women to consider a future in engineering, Texas A&M at Qatar cultivates relationships through community outreach. The Office of Student and Community Relations hosts informational sessions at local high schools, educating students about engineering careers and the Texas A&M at Qatar application process.

These young women say they chose Texas A&M at Qatar for a variety of reasons.

“Texas A&M at Qatar is turning young talents into engineers,” says Redissi, who opted to study at Texas A&M at Qatar because of the university’s warm atmosphere, excellent faculty–student ratio, and faculty and staff support. State-of-the-art laboratory equipment, hands-on experience and carefully designed curriculum also made Texas A&M at Qatar an attractive choice for her.

“Women are changing labels by pursuing engineering, and the best way we can serve the community is through science and technology.”

The university also offers young women a stellar engineering education within the country. Secretary General Ibrahim says, “Some families don’t want to send their daughters to schools outside Qatar. Education City provides them a good opportunity to learn here.”

Once they join the Texas A&M at Qatar student body, young women continue to create and expand educational resources for future female engineers.

Recently, students and faculty organized a campus chapter of the Society of Women Engineers (SWE). Worldwide, SWE has more than 20,000 collegeand professional-level members, and in 2009 the organization focused specific attention on the international arena.

Nora Lin, an engineer with Northrop Grumman and 2010 SWE president, says, “SWE will continue to expand internationally and support the needs of our international members.”

“Learn your potential and never give up.”

Al Bishri, president of the university’s SWE student chapter, says the group has established ambitious goals, including educating female students about the workplace, facilitating interaction between students and professional engineers, encouraging informal mentoring among members, and contributing to the larger Qatari community. The group’s main community service component will be outreach to local elementary and high schools, encouraging girls to consider a future in engineering. Many Qatari girls attend all-female high schools, so the SWE chapter wants to help them acclimate to and thrive in Texas A&M at Qatar’s integrated classrooms.

“Qatari girls are often quiet and shy, but they have hidden potential,” Al Bishri says. “We want to give those girls the green light.”

Redissi and electrical engineering senior Marwa Qaraqe say they both plan to attend graduate school. Qaraqe says she sees herself working in the oil and gas field or returning to Texas A&M at Qatar as a faculty member, and she says her family respects her goals.

“My family is very optimistic and thinks I will accomplish so much,” she says.

According to Ibrahim, Qatar aspires to be a role model for other countries in the region, and to do so, the country needs Qatari participation in the workforce. Currently, female workforce participation is climbing, but for that trend to continue, Ibrahim says the Qatari government must be proactive.

“We don’t just want girls to become educated, but to actually participate in the workplace,” Ibrahim says. “The government will have to help with flextime, nurseries and more.”

IRRIGATION Determining the best irrigation canal liner for Texas soil

Texas has an estimated 1.2 million acres of agricultural land irrigated via canals, many of which need renovation, according to a Texas A&M University irrigation expert.

Historically, irrigation canals were basically just earthen ditches, according to Guy Fipps, professor in the Department of Biological and Agricultural Engineering and a Texas A&M AgriLife Extension irrigation engineer. But the burgeoning water shortages over the past 15 years have increased awareness of the need to reduce water loss from canals through seepage.

Traditionally, the most common renovations were to replace smaller canals with pipelines and line larger canals with concrete, Fipps says. But lining canals with concrete is expensive and requires significant upkeep, particularly in Texas’ “shrink–swell” soils.

However, today irrigation districts have options other than just concrete.

“There is a revolution in materials sciences happening, with many new and innovative products coming on the market, including synthetic liners that are promoted for use in many applications,” Fipps says.

These new synthetic materials offer better, cheaper choices than lining canals with

Choosing the right liner, however, is not a simple task. Some liners are more suited to a given situation—and an irrigation district’s budget. The choice of liner also involves tradeoffs, such as ease of installation, durability, resistance to human and animal traffic, and cost.

To help irrigation districts make the best choices, Fipps and his associates recently completed a seven-year evaluation of nine synthetic canal liners in the Lower Rio Grande Valley.

“Initially, we used a very simple visual rating system,” Fipps says. “However, we quickly noticed that exactly the same material would fail completely in one location while remaining in excellent condition in others. Thus, our visual rating system evolved significantly over time as we sought to document the causes of such site-specific performance.”

Dr. Guy Fipps, P.E.

Biological & Agricultural Engineering Professor and Extension Agricultural Engineer 979.845.7454 g-fipps@tamu.edu

Fipps and his team eventually settled on a twostep process, combining a visual rating scale and quantitative analysis.

51

“The rating gives us an overall indicator of the condition of each project, and how the material fares over time,” he says.

“The quantitative analysis is used to interpret the ratings and to identify the factors that are likely causing lower ratings than would otherwise be expected.”

In August Fipps received the Advancement of Surface Irrigation Award from the American Society of Agricultural and Biological Engineers for his work advancing surface irrigation and saving water in Texas and abroad. The award documentation cites Fipps’ efforts in the Rio Grande Basin, where his work is credited with reducing water losses by irrigation districts by 240,000 acre-feet annually. (One acre-foot of water is equal to about 326,000 gallons.) Fipps was also recognized for his international work. Here, he consults with a farmer in Ghanzi Province of Afghanistan where for nine months in 2005 and 2006, he advised Afghans on issues related to water use, allocations and development.

52

With decades of experience evaluating and improving Texas irrigation systems, Fipps and his team anticipated some of the factors affecting performance.

Improper installation is one source of problems, he said.

Irrigation districts try to keep their costs low to minimize the fees that farmers and other customers pay. Some districts choose to install liners themselves, leading to various problems if the staff is not sufficiently trained.

Poor installation issues include poor anchoring of the liner at the top of the canal, improper seams of liners around gates, valves and other structures, and inadequate stretching of liners at installation.

“Water seeping under the top anchor can result in floating and even buckling of concrete being used as a protective barrier,” Fipps says. “Proper seaming of materials around structures, gates and valves takes skill. District personnel may not have sufficient training or use the right products.” engineeringmagazine enginee ringmagazine .tam u .e .ed du

Other factors that influence liner choice are smoothness and stability of the material underneath the liner.

“Some of the thinner liners definitely shouldn’t be used over cracked concrete, as they are easily pierced,” he says.

And both human and animal traffic also turned out to be significant factors.

“The rating gives us an overall indicatoroftheconditionofeach project, and how the material fares over time. The quantitative analysis is used to interpret the ratings and to identify the factors that are likely causing lower ratings than would otherwise be expected.”

“Do kids swim in the canals?” Fipps says.

“Much of what we classified as ‘unintentional damage’ appeared to be caused by kids grabbing onto folds or loose spots in the liners while pulling themselves out of the canal.”

Also, cattle hooves can puncture some of the thinner materials, he says. Mowing near where the liner is anchored to the top of the canal was responsible for other damage.

“Then there’s the maintenance factor,” he says. “Timely maintenance and minor repairs can prevent small problems from becoming serious.”

Fipps and his associates rated several types of liners to find the best overall renovation: a synthetic liner with a protective barrier on top of concrete, or shotcrete.

Beyond that, it gets complicated, Fipps says, depending on kids, cows, mowing, installation expertise and, of course, money.

A&M System water center to focus on statewide issues Texas A&M University System Chancellor John Sharp announced the formation of a new A&M System center to address multiple water issues in and develop solutions for Texas.

Texas A&M AgriLife Research, Texas A&M AgriLife Extension Service, Texas A&M Engineering Experiment Station (TEES) and Texas A&M University–San Antonio are collaborating on the development of the Water Conservation and Technology Center, which will support high-priority projects that focus on Texas’ water issues.

“The state of Texas has a rich history that has always been linked to water—rights, conservation and control. This unique agency collaboration will lead to development of more efficiency and effectiveness in managing this vital resource,” Sharp says.

Administered by the Texas Water Resources Institute (TWRI), an entity of the A&M System, the center will increase the system’s ability to meet existing and emerging statewide needs in water conservation and technology, according to Neal Wilkins, TWRI director.

“The center will accelerate the development and adoption of new and innovative technologies to solve emerging water problems and meet future water supply needs,” Wilkins says.

The center includes a collaborative relationship with TEES through its Texas Center for Applied Technology and will be located at the TEES South Presa campus in San Antonio.

TEES’ Cindy Wall says the center will target its work on four highpriority efforts: water conservation, water reuse, groundwater desalination, and energy development and water use.

“The center will establish a team of scientists, engineers and water professionals dedicated to applied research and development, testing and validation, technology transfer, and training and extension education in these four areas,” Wall says.

The center will work with industry, state and federal agencies, municipalities, trade associations, and other research institutions to undertake projects and develop solutions within these four areas.

“Also, there’s little difference between the cost of the various liners, but skill levels in the field vary widely,” he says. O 53

Saving energy–and money Continuous Commissioning process helps save more than $100 million in energy costs ®

000,000 W

ith tightened budgets and slashed funds, energy efficiency has been thrust to the forefront, and one entity of The Texas A&M University System is doing its part to help System members, as well as other government agencies, save money and increase energy efficiency in their buildings.

Through a program known as the Continuous Commissioning® process, the Energy Systems Laboratory (ESL), a center in the Texas A&M Engineering Experiment Station (TEES), has worked to produce more than $100 million in savings in more than 300 buildings throughout Texas, the United States and the world.

The Continuous Commissioning process uses an ongoing effort to resolve operating problems, improve comfort, and optimize energy use for existing commercial and institutional buildings and central plant facilities. TEES has trademarked the process, which is being commercialized through the Texas A&M System’s Office of Technology Commercialization.

55

“When I was growing up, we tuned our cars up pretty often, and that could make a significant difference in gas mileage,” says David E. Claridge, director of ESL and a professor in the Department of Mechanical Engineering at Texas A&M University. “The Continuous Commissioning process is a structured process for providing that kind of tune-up to building operation.

“It is a systematic way of looking at buildings and locating problems, and then working with the building operators to correct them.”

The origins of Continuous Commissioning saving money at Texas A&M date back to 1995, when the idea was first brought to thenPresident Ray M. Bowen. After being briefed on the process, Bowen’s financial vice president was significantly impressed and scheduled a meeting with Bowen and individuals from ESL. Bowen, who has an engineering background, was duly impressed and told his financial vice president to find the money to make Continuous Commissioning happen on the Texas A&M campus.

Saving homeowners money, too The work of the Energy Systems Laboratory (ESL) is not limited just to industry. The center also helps homeowners throughout Texas achieve energy savings.

A recent ESL study found that adopting and implementing energy codes for new-home construction saved homeowners more than $1.7 billion statewide. The study covered eight years after the passage of the Texas Emission Reduction Plan (TERP).

According to the study, more than 1 million homeowners in Texas who benefited from energy-efficient new homes saw an average reduction of $201 in their utility bills.

A major energy-efficiency element of TERP is the establishment of the Texas Building Energy Performance Standards, which define the building energy codes for all new residential and commercial building construction statewide.

ESL is responsible for helping to implement energy codes statewide, including reviewing and recommending state adoption of new building energy code editions.

ESL also reviews local code amendments and offers technical assistance to local municipalities, cities and councils of governments. ESL is the prime source for energy-code information and training for the entire building community and is responsible for analyzing the energy savings and the resultant emissions reduction from energy efficiency and renewable energy programs under TERP.

A decision was made to take money from the campus’ utilities budget, giving the process its start, but also putting pressure on then-ESL Director Dan Turner, Claridge and their colleagues to produce results somewhat quickly.

“Knowing that the utility budget was a biennial budget, we knew we had to save enough in two years to pay for the work we were doing,” Claridge says.

The total savings in just the Kleberg building were almost enough to recoup the initial startup cost of the meters for the program.

Before they could even begin to study the energy efficiency of the buildings on campus, heating, cooling, and electric meters had to be installed, leading to an initial output of nearly $750,000.

“A key aspect of this is you need to have measurements of the energy going into the building before you can effectively see what you are accomplishing,” Claridge says.

After installing meters in the first 20 buildings, data were analyzed and a decision was made to focus on the Kleberg building, which then was just under 20 years old and was using a great deal of heating and cooling. engineeringmagazine enginee ringmagazine .tam u .e .ed du

The Austin City Hall realized savings of more than $70,000 during the first 12 months Continuous Commissioning efforts were implemented.

The ESL group found that in an effort to fix humidity problems in the building, the air coming into it was being heated to 110 degrees, then immediately being cooled to 55 degrees.

The coils used to heat the air were designed to come on only if the outside temperature was near freezing. This parameter would keep the outside air warm enough to prevent freezing in any part of the ventilation system.

But in the effort to combat the humidity in Kleberg, the coils were left on continuously.

“It was one of those things where you have a very vexing problem and you are trying to figure out how to fix it,” Claridge says.

“Somewhere along the way, someone thought of this and those problems seemed to go away.”

Simply turning off those coils saved nearly $200,000 per year, according to Claridge.

Going through the rest of the building, finding other problems and making modifications, saved another $200,000 per year.

The total savings in just the Kleberg building were almost enough to recoup the initial startup cost of the meters for the program.

“The savings in that building were significantly more than the total operating cost of many

“When I was growing up, we tuned our cars up pretty often, and that could make a significant difference in gas mileage. The Continuous Commissioning process is a structured process for providing that kind of tune-up to building operation.” similar buildings on campus,” Claridge says.

“We immediately saved essentially enough to pay for the metering on the whole campus in two years in just that one building.”

The savings were also enough to sway Bowen, who admitted some years later that he was initially skeptical of the concept.

“A number of years after the program was started, President Bowen says, ‘When I first heard of this, I thought it had about as much chance of working as room-temperature fusion did,’” Claridge says.

The program has expanded on campus and continues today in more than 80 buildings on the flagship campus in conjunction with the university’s Utilities and Energy Management department.

57

Through the use of Continuous Commissioning® process, the Dallas/Fort Worth International Airport has realized more than $13 million in cumulative energy savings.

Several other campuses in the A&M System have also implemented the program, including Texas A&M International University in Laredo, where Claridge says they have done the most work, cutting campus consumption by 15–20 percent.

The effort has also spread throughout the state to such entities as the Brooke Army Medical Center in San Antonio, where it produced 10 percent savings in a brand-new building; the Alamo Colleges in San Antonio; Dallas/Forth Worth International Airport; and IBM. Dr. David Claridge, P.E.

58

Also, through licensees, more than 30 military hospitals worldwide and a dozen Veterans Administration hospitals are using the program.

Recently a new project was started with the Texas Facilities Commission in Austin, continuing ESL’s efforts in an area where it is also using the Continuous Commissioning process in Austin Independent School District buildings and in conjunction with Austin Energy’s Building Tune-Up Program.

“The Continuous Commissioning process ended up being significantly more successful than our initial estimates,” Claridge says.

“You can say we hoped it would be successful, but we certainly had no idea how much it would save.

“I wouldn’t have said we are definitely going to be able to save an average of 15 or 20 percent.

There is no way I would have said that. People would have laughed us out of the building.” O

ENERGY SYSTEMS LABORATORY

T

he Texas A&M Engineering Experiment Station’s Energy Systems Laboratory was formed in 1985 primarily to conduct energy efficiency research in building systems and industrial facilities. It also brings energy efficient assessments and improvements to scores of public buildings, schools, and private enterprises across Texas through research and deployment of energy-efficient technologies and techniques, including the integration of renewable energy sources in buildings.

The Energy Systems Lab has helped Texans save hundreds of millions of dollars by increasing energy efficiency of buildings, including the Dallas/Fort Worth International Airport, the Texas Health and Human Services Commission, the U.S. Army Medical Command at Fort Sam Houston, and at city, county and private sector buildings.

Building cooling and heating optimization work Current and past public and private projects include: • Dallas/Fort Worth International Airport o $13 million in documented savings o Named the 2010 Energy Project of the Year by the Association of Energy Engineers • Texas A&M main campus o More than $75 million in savings since 1995 o Texas A&M’s campus energy use is 44 percent less per square foot than in 1993 • Texas A&M International University Green Campus Initiative o $1.6 million in savings since 2005 o TAMIU’s campus use is 28 percent less per square foot than in 2000 • U.S. Army Medical Command o More than $20 million in savings in 33 hospitals worldwide • Alamo Community Colleges in San Antonio o $7.8 million in savings since 2002 • IBM Global Energy Management o More than $3 million in savings since 2005

SIMULATOR BECOMES REALITY A piece of U.S. space history comes to Texas A&M Now that NASA’s space shuttle program has ended, relics from the program’s 40-year history are scattered across the United States. The Shuttle Mission Simulator, or SMS, will find a new home at Texas A&M University.

The simulator has trained 355 astronauts for 135 missions and will be the only large piece of equipment from the NASA space shuttle program that will remain in Texas. The Department of Aerospace Engineering is spearheading the effort to move the fully operational simulator to Texas A&M for researchers, the public and students of all ages to use for many years to come.

The simulator is expected to open to the public in summer 2013.

AN EDUCATOR’S PERSPECTIVE

John Valasek Professor Aerospace Engineering

Texas A&M

University will soon have a new attraction for current students and researchers to use and learn from, and for space enthusiasts to visit, when the NASA Shuttle Mission Simulator (SMS) opens to the public in summer 2013.

This opportunity wouldn’t have come about without NASA’s Paul S. Hill ’84, director of Mission Operations at NASA Johnson Space Center. Hill contacted us about this great opportunity to bring this one-of-a-kind experience to Texas A&M so that current and future students could benefit from this, see how engineering is done in the real world, see how NASA prepared astronauts to fly into space, and see a big part of the history of the U.S. space program.

NASA built this simulator in the late 1970s, and it operated daily until 2011. Every astronaut who has trained to fly the space shuttle has flown this simulator. This sophisticated tool—the only device of its kind—trained astronauts to use the space shuttle to launch into space and fly back to Earth.

We plan to restore the simulator to the way it was when the last mission flew in July 2011. Those astronauts who flew that last mission will be able to come to Texas A&M, sit in the simulator and say, “That’s exactly how I remember it.” It’s going to be a time capsule, frozen in time so that everyone who comes to see it and fly it will get to experience a piece of space history.

OPINION

And it’s living history. Unlike a typical museum display, where you look at exhibits and read a placard, this is history that you actually get to interact with. You’ll get to sit in it, fly it and run the full simulation exactly how the NASA astronauts did.

The simulator will also complement our education and research efforts in the Department of Aerospace Engineering. Our Vehicle Systems and Control Laboratory has simulators for a variety of aircraft, from general aviation to large commercial air transports, such as the Boeing 787, to various types of military aircraft, such as the F-35 Lightning II. The SMS is also a flight simulator, but of a space vehicle. So the basics are the same—the dynamics, the atmospheric models, the cockpit, all the interfaces and displays for the pilots—but the SMS is specialized for space travel.

You’ll get to sit in it, fly it and run the full simulation exactly how the NASA astronauts did.

Several courses in aerospace engineering and other engineering departments will use the simulator—for example, evaluating cockpit– human factors or studying flight mechanics or guidance, navigation, and control. For some courses, we envision creating laboratory sections in which students will use the simulator as part of their work. The SMS will also be available to faculty and students for research, in addition to companies, organizations or individuals who wish to conduct research under contract. Public school students and teachers will also have ample opportunity to experience the SMS. And this opportunity wouldn’t be happening without the dedicated students of Texas A&M.

Right now they’re doing inventory and helping with site preparation. Students in aerospace engineering honors classes have been working up lesson plans for K–12 teachers and for aerospace engineering courses and laboratory sections at Texas A&M. Members of the Texas A&M chapter of Students for the Exploration and Development of Space are designing the SMS Experience, an immersive experience for the facility, to include everything from selecting the pictures on the wall to the videos shown in the waiting-area monitors to the music playing over the loudspeaker. We want the shuttle simulator experience to be as good as visitors expect it to be, and better.

Approximately 1,000 people each year visit the Vehicle Systems and Control Laboratory on campus to fly the simulators, but I anticipate that visits to the SMS will easily exceed that number. And that’s what we want: to make this facility available to the public to see, interact with and learn from. I’ve already been contacted by people all over the country who want to plan their summer vacations around bringing their families here to fly the simulator.

We will have a significant piece of the space program sitting right here at Texas A&M so that space enthusiasts can come visit it and get to see something on the same quality and significance level as anything at the National Air and Space Museum or one of the NASA museums. So lots of people are excited, and I’m excited too because this will be the only large piece of the space shuttle program that will remain in Texas. I’m excited that Texas A&M students, faculty, former students and friends will be able to use and enjoy it, and get to experience just a little bit of what flying into space on the shuttle is like. You won’t be able to do that anywhere else in the world.

I’d like to be the first one to fly the SMS once it’s up and running here, but I’ll reserve that honor for the student technicians who have worked so hard on it. I flew it when it was at NASA, so I know the experience everyone will have—and it’s going to be good. Even though I have worked on and flown simulators in industry and academia for my entire career, flying the SMS was still even better than I thought it would be. Everyone needs to experience this—it’s great! O

A CURRENT STUDENT’S PERSPECTIVE

Lisa Warren ’12 SMS student volunteer coordinator and aerospace engineering major Every good Aggie will boast of Texas A&M’s prowess and grandeur. College Station will soon be a national landmark as home of the only Space Shuttle Mission Simulator (SMS) in existence. I am excited that we are receiving not only a vestige of space exploration history but also a critical piece of American history.

The SMS has been a crucial part of the space shuttle program since the program began in the 1970s. Every astronaut who has undertaken a shuttle mission has trained on this extraordinary machine. The SMS is the only major item from the shuttle program that is staying in Texas after the final mission in July 2011.

A team from NASA will assemble the SMS at the Texas A&M University Services Building.

The team of student volunteers is aiding reconstruction of the SMS in several ways, including the inventory of parts arriving from Johnson Space Center. Multiple interior walls had to be demolished to install the simulator, and the walls will be rebuilt the full two stories after the simulator’s reconstruction.

The student volunteers will continue to assist with every aspect of the up-and-coming SMS program. The next step will be to design and set up the area where the SMS will be housed to ensure that the overall experience is out of this world.

When I was a kid, astronauts and the space program fascinated me. I have wanted to know what experiencing spaceflight would be like since the first time I was exposed to the idea of humans going to outer space at Hardin-Simmons University day camp. This interest continued to develop during my sixth-grade field trip to Johnson Space Center.

Never in my wildest dreams did I think I might one day fly the SMS, much less be a part of the group maintaining this living piece of history to inspire future space enthusiasts.

I think all college students reach a point in their careers when they ask themselves, “Why am I doing this?” As a senior majoring in aerospace engineering, I have asked myself this very question on many occasions. But experiences such as working with the SMS remind me why I love aerospace engineering, and that’s what gives me the desire to prevail.

Working with the SMS has reignited the spark that is my passion for aerospace.

Working with the SMS has reignited the spark that is my passion for aerospace. It will be a living piece of history and act as a beacon to future Aggies. We will always be able to remember the significance of the space shuttle program, and having the SMS will allow anybody to experience it firsthand. O

A FORMER STUDENT’S PERSPECTIVE

Paul Sean Hill ’84 Director, Mission Operations NASA Johnson Space Center The Shuttle Mission Simulator (SMS) Motion Base Simulator (MBS) is on its way to reactivation in Aggieland by the aerospace engineering department. What a poignant transition for this historic simulator, NASA’s manned space program and Aggies.

As the name implies, the MBS is a full-fidelity cockpit and full-motion space shuttle simulator. In fact, it is the single full-motion shuttle simulator used by every one of the 852 people from 15 nations who flew on shuttle missions throughout that program’s 30-year flight history. This machine, driven by the same software that also controlled the shuttles, was used extensively in preparation for all 135 shuttle missions, from 1977 through July 2011, for spacecraft software testing, piloting technique development, and astronaut and mission control training.

Imagine what it means to more generations who will have access to the touch and feel experienced by real, spacefaring shuttle astronauts.

A primary role of the MBS was to ensure that astronauts flying a shuttle felt as routine and “normal” as possible while riding into space at the tip of millions of pounds of fire, or flying through a cloud of fire during reentry at the end of a mission. More critically, the MBS was a key platform on which to practice a seemingly infinite combination of shuttle system failures and emergencies during all phases of spaceflight, also ensuring that the astronauts and Mission Control were prepared for anything this dangerous business conjured up.

64

As a freshman aerospace engineering student in the fall of 1980, and just before the first launch the following spring, I watched my dad, Larry Hill ’56, a NASA manager at Johnson Space Center, describe the shuttle flight profile in the Rudder Auditorium to a group of students and professors. More than 30 years later, I managed both the training that employed the MBS and Mission Control. In that same capacity a few months after the last shuttle landed, I signed the legal agreements with Texas A&M President Bowen Loftin that delivered the MBS to my university and my aerospace engineering department. In the space left behind the MBS, NASA has already begun developing simulators for next-generation spacecraft.

In the summer of 2013, John Valasek and his team in the aerospace engineering department will reactivate this historic simulator in Aggieland. He plans to get much more life out of the MBS, including Aggie and public access to simulated shuttle flight and a range of flight development projects. Valasek also has insisted on keeping all equipment touched by NASA astronauts exactly as it was when astronauts flew their last MBS sortie.

Imagine what it means to more generations who will have access to the touch and feel experienced by real, spacefaring shuttle astronauts, and to the engineering students who lead projects with the MBS that still has that historic authenticity. And those experiences are just up Highway 6 from NASA Johnson Space Center at Texas A&M University.

Again, what a poignant transition for this historic simulator, NASA’s manned space program and Aggies. O

Nuclear Materials Under Extreme Conditions Designing advanced materials for next-generation nuclear reactors To build safer, longer-lasting nuclear reactors, researchers need advanced materials that can withstand the harsh environment inside a reactor.

Lin Shao, an associate professor in the Department of Nuclear Engineering, is a materials physicist on the hunt for these advanced materials. Shao’s research focuses on understanding why materials fail, particularly in the harsh environments inside a reactor, such as high temperature, stress, corrosion and neutron damage.

The aim of the research is not only reactor safety but also reactor economics and nuclear waste management. Since 2007, Shao’s research group has received $8.3 million in funding, primarily from the U.S. Department of Energy and the National Science Foundation.

Shao and his collaborators study a variety of materials, from stainless steel, which was used as cladding material (the hollow tube used to contain nuclear fuels), to ceramics and even concrete.

65

“We need to test these materials to get an idea of how long the materials will last,” Shao says, “and we need to understand what the mechanism is behind these failures so we can come up with a strategy to have better material development so the materials can have a longer lifetime.”

Aiding in this study is the country’s largest university radiation facility, Shao’s Ion Beam Laboratory, with five accelerators providing the particles at various energies that are needed to simulate what happens inside a nuclear reactor—in a relatively short time.

Unique capabilities

Aiding in this study is the country’s largest university radiation facility, Shao’s Ion Beam Laboratory, with five accelerators providing the particles at various energies that are needed to simulate what happens inside a nuclear reactor—in a relatively short time.

“Previously, if someone said, ‘This material is good and can be used as a structural component inside a reactor,’ we can test to see whether that’s true,” Shao says. “We could put this material inside a reactor and irradiate it for a long time—probably five or 10 years— and then evaluate the damage.

“But we just can’t afford to wait such a long time,” he continues. “Therefore, we use our accelerator to create those high-energy, strong beams to simulate radiation damage and get a very quick answer. Our machines are very capable. For example, one day of exposure to radiation from an accelerator can represent a few years of the radiation inside a reactor.”

Shao says the capabilities of the five accelerators can be combined with those of the Texas A&M Cyclotron Institute, which produces very high-energy particles, and the university’s Nuclear Science Center, which can supply gamma and neutron particles.

66

“Combine these facilities, and we have unique capability to carry out systematic research,” Shao says.

The unique capabilities of Shao’s lab have led to several subcontracts from various national laboratories that lack the kind of radiation testing facilities needed to test material behavior.

Different types of damage

Shao uses the example of stainless steel cladding. An energetic particle of radiation can rupture the atoms that make up the steel tube, causing damage that sets off a chain reaction that can lead to failure.

“You have this perfect stainless steel inside, but the neutron will cause damage and that damage will cause trouble,” he says. “That is the fundamental reason that we have so many nasty conditions inside a reactor.”

Swelling is one example of the damage that can occur. The atoms of a particular material are arranged in a certain shape. But left inside a reactor for a few years, the shape changes and grows.

“If you’re able to see what’s inside, you’ll find it’s like Swiss cheese,” Shao says. “The material begins to have a cavity inside due to this damage. It used to be okay to have 5 percent swelling, but in the next generation of nuclear reactors, even 1 percent swelling will cause a safety issue. So therefore, the whole field is hungry to find what is the best material that can suppress this kind of swelling enough to keep the structural integrity.”

Materials inside a nuclear reactor may also experience cracking. That can happen when stainless steel that contains nuclear fuel comes into contact with coolant, usually water at about 400–500 degrees Celsius in current reactors but will be about 1,000 degrees Celsius in next-generation reactors. After a few years, that water will begin to interact with the stainless steel and cause cracking. If this cracking cannot be stopped, then the nuclear fuel is exposed to coolant, contaminating the whole loop and causing accidents.

engineeringmagazine enginee ringmagazine .tam u .e .ed du

Gas atoms that accumulate inside a metal can form bubbles, similar to the bubbles seen around the edge of a pancake while it’s being cooked. Neutrons interacting with the material create these gas atoms.

Shao says it’s fair to blame all accelerated materials failures on neutrons, in fact. Neutrons destroy the original material structures through two types of interactions: nuclear reactions that create energetic fission fragments and direct neutron scattering in which the neutron knocks one atom out of its original location. A given atom can be pushed around by either fission fragments or directly by neutrons and get relocated up to hundreds of times.

“So no matter how good a material is at the beginning, everything will get messed up at the end,” Shao says.

Neutron damage also changes the water chemistry inside the reactor so that the water behaves like an acid. Therefore, corrosion damage is also of concern to nuclear engineers.

We need to test these materials to get an idea of how long the materials will last, and we need to understand what the mechanism is behind these failures so we can develop materials with a longer lifetime.

Cracking, swelling, bubble formation and corrosion are just several typical ways that materials inside a reactor can fail. In reality, these failure mechanisms are correlated into each other and the combined effect is far more severe.

Shao directs the largest university radiation facility in the country, with five accelerators to create high-energy particle beams needed to simulate radiation damage.

The complexity of these materials issues has driven the nuclear materials research from large-scale descriptive studies into atomicscale fundamental studies, which requires collaborative researches across the fields of engineering, physics and chemistry.

“Thanks to the excellent collaborative research environments at Texas A&M, we are lucky to find many partners having common interests in these areas,” Shao says.

Understanding damage on the atomic level Shao says that in addition to testing, his research group seeks to understand the mechanism behind the behaviors observed.

To do that, the researchers have established a strong modeling program to “see” what experiments can’t see. One collaboration with Tahir Cagin, from the Artie McFerrin Department of Chemical Engineering, has allowed the researchers to understand how some metals and ceramics react when bombarded with radiation.

67

“We are able to catch those atom interactions at a very short time scale, to go beyond the experimental capability there. We combine experiments and modeling to get an understanding of the mechanism behind material failure.”

Shao says the need for more safety in nextgeneration reactors drives this push for better material design, and that means studying nanostructured materials at the atomic scale.

If you put two different materials together, the boundary (or interface) between these two different kinds of materials has a unique effect of trapping defects caused by radiation damage. These boundaries between materials, if they can be stabilized under neutron damage, behave as trash cans, collecting the garbage, or damage, created by radiation.

“Our key interest is trying to maximize this interface region so the material will have a self-annealing effect: The material will repair the damage itself.”

This garbage-collecting property leads Shao to expect that these nanoengineered materials will have a significant impact on material design, with longer lifetime inside a nuclear reactor. This particular area of study has led to several research grants, including Shao’s National Science Foundation CAREER award in 2009.

“We want to match modeling and simulations, to actually see individual atoms,” Shao says.

“So we use transmission electron microscopy to see what happens at the metal–metal interface when we put two metals together and bombard with particles.”

Most recently, Shao proposed to bond metals with ceramic glasses to create a new type of interface. The work has been funded by the U.S. Department of Energy as a collaborative project with the University of Nebraska at Lincoln and the Massachusetts Institute of Technology.

Benefits of nanostructured materials

An energy particle is like a bullet, bombarding the material and causing damage inside.

With bulk material—say, a lump of silicon— that energy bullet after one picosecond causes cascading damage by displacing all the atoms in the matrix. But when the same energy bullet is fired at a small nanowire, such as a fiber tube, the same radiation causes very few defects inside.

“That’s the interface effect we are talking about,” Shao says. “Our key interest is trying to maximize this interface region so the material will have a self-annealing effect: The material will repair the damage itself.”

One way to increase this boundary, or interface region, is to order the atoms in a polycrystal, a large crystal made up of many smaller crystals.

“Our desire here is trying to maximize those boundaries so each material inside will have a domain, a crystal as small as possible so we can maximize those regional interfaces. If we can do that, we can trap more defects there to stop damage from spreading.”

Major focus

A major focus of the research team is cladding material. That hollow tube serves as the first buffer layer between the coolant and the nuclear fuel—a critical function, Shao says.

Shao cites the Fukushima nuclear reactor accident in Japan as an example of just how critical cladding material can be.

“Everybody talks about that reactor accident.

That accident came from the fact that the fuel cladding, that hollow tube, was made of zircaloy, a zirconium-based alloy. That alloy works very well at normal operating temperature, 500 degrees Celsius. But after the tsunami, due to the coolant being shut off, the water became very hot. That hot water interacted with the zirconium and released a huge amount of hydrogen. That’s what caused the explosion there.

engineeringmagazine enginee ringmagazine .tam u .e .ed du

“So you can see that material selection for that cladding material is critical. So that is the trend in this country, trying to replace zirconium.”

“We do whatever we can do to find the best material that best performs under that normal operation temperature, but who knows what will happen if we have an accident? Anything can happen, so we try to say, ‘Are we able to structure this so we find a better material, which is safer even in extreme conditions?’”

Shao is investigating using a silicon carbide composite to replace zirconium in cladding material in order to avoid the situation in the Japan reactor. Because silicon carbide is a ceramic, no hydrogen will be released when (or if) the cladding interacts with hot water. And using fiber bundles of silicon carbide rather than bulk silicon carbide helps to strengthen the material.

“If you had a material made of just bulk silicon carbide, and you tried to bend it, it would crack,” Shao says. “But silicon carbide fiber material can be bent to minimize cracking.

When you push or displace a fiber, it pulls out of the matrix and then can go back into its shape. So you have a way to release the stress.

Therefore, we do whatever we can do to find the best material that best performs under that normal operation temperature, but who knows what will happen if we have an accident? Anything can happen, so we try to say, ‘Are we able to structure this so we find a better material, which is safer even in extreme conditions?’ O

Study abroad: China In summer 2012, Shao and 15 Texas A&M nuclear engineering students studied in China for several weeks. Faculty members Jean Ragusa and Cable Kurwitz also accompanied the Texas A&M delegation.

Shao says big things are happening in nuclear engineering in China.

“In China, the largest nuclear engineering program has more than 1,000 students, much larger than our program, and the nuclear engineering program at Texas A&M is the largest program in the United States,” Shao says.

After lectures from both Texas A&M and Chinese university faculty, the Aggie and Chinese students toured several nuclear power plants.

“The beautiful thing about this summer school is that our students had the chance to see those nuclear power plants under different stages of construction, which is very valuable. Once a nuclear power plant is constructed, you cannot see inside. You can get some idea of management, see the cooling swimming pool, the waste management, see the control panel, but you won’t be able to see inside.

“In China, they have 26 nuclear power plants under construction right now, and in the United States we only have one. So that was quite an exciting opportunity for us.”

oads R Software helps predict pavement damage for better, longer-lasting roads

Take a drive on any Texas highway and you’ll see no shortage of orange traffic signs warning of road construction. In fact, to the state’s irritated drivers, it seems as if half the highways in Texas are constantly under repair.

But new software developed by a team led by Texas A&M Engineering researchers takes into account weather and traffic conditions to help builders design better, longer-lasting roads.

The Asphalt Research Consortium, or ARC, was founded more than 10 years ago to address a fundamental issue—asphalt, says Dallas Little, professor in the Zachry Department of Civil Engineering and a distinguished member of the American Society of Civil Engineers. Specifically, the ARC focuses on the bond between asphalt and its various aggregates, as well as asphalt’s susceptibility to damage from aging and moisture.

“Say where you want a road to be— Houston or Fargo, N.D.—what kind of traffic the area has, what kind of asphalt type, and so on. PANDA can account for all these factors in the performance predictions.

A major result of the research consortium’s work is PANDA (Pavement Analysis Using Nonlinear Damage Approach), a state-of-theart, three-dimensional computational code that can predict when and where pavement damage will occur. And this prediction can help road planners and builders build better pavement.

The congressionally mandated consortium was funded by a transportation bill (now under extension) through the Federal Highway Administration with about $30 million over six years to evaluate asphalt infrastructure performance.

“We answer to the U.S. Department of Transportation, state departments of transportation, industry, academics and area leaders—all representing the driving public,” says Little, who is a Distinguished Member of the American Society of Civil Engineers.

“The end goal is this model that will be able to enhance pavements to extend the lives of our roads and their sustainability.”

Complex material, complex research team

Pavement is complicated, Little says. It’s made of a very fine mineral filler and aggregate (both sand and gravel-sized rock), bound together by the viscous, sticky black liquid called asphalt that comes from crude oil. The complexity of the composite is due to the physical and chemical reactions between components.

Asphalt is dynamic, and air voids and moisture in the mixture can harden and stiffen the material over time.

To address this complexity, the interdisciplinary consortium brings together experts in materials science and engineering, chemistry, and transportation. Little, with his expertise in materials engineering, leads Texas A&M’s research team. His insight into asphalt material feeds into the PANDA model. Eyad Masad, a professor at Texas A&M University at Qatar, brings computation expertise to the team. Charles Glover, professor in the Artie McFerrin Department of Chemical Engineering, is an expert in asphalt chemistry and is part of the Texas A&M team, along with Robert Lytton, a micromechanics expert in the civil engineering department. And Rashid Abu Al-Rub, a former assistant professor at Texas A&M, lent his invaluable expertise in structural mechanics.

And that’s just at Texas A&M. A major ARC partner is the Western Research Institute at the University of Wyoming. Little says WRI has some of the best asphalt chemists in the world because of the institute’s previous life as a U.S. Department of Energy research facility with particular expertise in shale oil.

Researchers at the University of Nevada–Reno are studying tire–pavement interaction to work that knowledge into PANDA. Other collaborators include Advanced Asphalt Technologies in Sterling, Va., the University of Wisconsin-Madison, the University of Texas at Austin, the University of Nebraska– Lincoln and the University of Illinois at Urbana-Champaign.

“ARC is big and diversified ,” Little says. “We have many researchers who are focused on solving one of this country’s major infrastructure problems.”

Realistic model

Current models make simplifying assumptions and gloss over important aspects. Better life-cycle information can make for a more thorough model to help save money and extend road life.

72

“We want to be able to predict performance— any type of damage, whether from fatigue cracking, rutting or moisture damage, or a combination of all,” Little says. “But most existing models are based on empirical methods and experimentation.”

The PANDA project is different because it integrates fundamental material properties of asphalt and the mineral aggregate components into a mechanistic model. And to do that, researchers must truly understand asphalt: What properties cause what kind of damage? Can that knowledge be put into a model or computational tool to help planners and builders design pavements? And can existing materials be used to build these roads, or will new materials need to be designed?

Road builders have to build different road types in different areas on the basis of information specific to those areas, such as climate and traffic conditions, Little says.

“These conditions affect how pavement will perform over a certain life cycle,” Little says.

“So we have to know if the pavement will sustain those conditions, whether and how it will deteriorate, what precautions should be taken, and what kind of maintenance plan will need to be developed. The basis for all this is a good model founded on fundamental material properties, and it’s all part of PANDA.”

Road builders have to build different road types in different areas on the basis of information specific to those areas, such as climate and traffic conditions.

Little says one notable advancement of PANDA is a rather sophisticated approach: applying the dynamics of an actual wheel as it moves over pavement. Researchers at the University of Illinois, ARC’s most recent partner, offer invaluable expertise in this area.

Now PANDA can actually model a realistic moving wheel, not just a static load.

“Say where you want a road to be—Houston or Fargo, N.D.—what kind of traffic the area has, what kind of asphalt type, and so on,” Little says. “PANDA can account for all these factors in the performance predictions.”

The Texas A&M Transportation Institute Saving lives, time and resources Dallas Little is also a senior research fellow in the Materials and Pavements Division of the Texas A&M Transportation Institute (TTI); he was the first researcher named to that position at TTI. At TTI, Little develops new research initiatives with government and private entities.

Established in 1950, TTI is recognized as one of the finest transportation research agencies in the nation and helps prepare students for transportation careers. TTI has a breadth and depth of programs, facilities and capabilities unsurpassed by any higher education–affiliated transportation research program in the United States.

Agency researchers seek solutions to the problems and challenges facing all modes of transportation. TTI conducts about 600 research projects annually, with more than 200 sponsors at all levels of government and the private sector. In 2011, TTI had research expenditures totaling $50.1 million.

Through strategies and products developed through its research program, TTI has saved Texas and the United States billions of dollars. Institute researchers have made significant advancements in transportation safety, mobility, planning, systems, infrastructure, the environment, and other areas vital to an efficient transportation system and good quality of life. TTI research has a proven impact, saving lives, time and resources.

At any one time, TTI has research sponsors in about 30 states and has conducted research for sponsors in all 50 states and in 20 countries. In the laboratory and the classroom, through the Dwight Look College of Engineering and other colleges at Texas A&M, TTI researchers help prepare students for transportation careers.

TTI’s 10 state and national research centers illustrate the scope of the institute’s research program. Center research emphasis areas range from transportation safety and economics to railway, border mobility, and ports and waterways research.

Microstructural changes

The software model is also important for predicting performance of pavement on a microstructural level.

“We can also use PANDA to design the asphalt itself,” Little says. “We can predict how a certain mixture will behave if you change constituents—the type of asphalt binder, the rock source, the air void content, whether the voids are saturated with water, or if modifiers including nanomaterials or polymers are used. PANDA can help predict how much the overall pavement properties will change when the microstructure changes, so it’s a material design tool as well.”

For an example of the nanoscale investigations being considered for input into PANDA, graduate students are using an atomic-force microscope to determine what happens when polymers are added to asphalt. Knowing the nano-, meso- and microstructural changes that occur can help pavement engineers assess specific mechanisms and therefore develop better ways to modify material properties at all length scales.

“This is a much smaller scale than has ever been considered before in this field,” Little says. “So incorporating this information into our model is a big step. We are not quite there yet, though, but that is our next step.”

The model also accounts for asphalt’s complex material behavior.

74

Little says that asphalt is almost like a living body: Damaged asphalt can partially “heal” and fix itself when left alone and under certain conditions. This healing property—what drives it and how it can be used to extend the life of pavement—is another aspect that the research team has studied and incorporated into the model.

“PANDA is a virtual experiment that will give the highway community the ability to easily perform ‘what if’ scenarios and decide how best to build a road that will last.”

The team is completing software development, validating the software in laboratory and field tests, and working to make the program more user-friendly for wider use.

“PANDA is a virtual experiment,” Little says.

“PANDA is capable of evaluating how pavement will respond under loading as the pavement ages and is exposed to air and moisture.

News A&M System awarded $285.6 million for national center for innovation The Texas A&M University System has been awarded a contract to develop one of three U.S. Department of Health and Human Services Centers for Innovation in Advanced Development and Manufacturing.

The contract, with a duration of up to 25 years, builds upon investments by the A&M System and the state of Texas in growing new jobs in the burgeoning biopharmaceutical industry.

The $285.6 million contract includes an initial investment of $176.6 million from the U.S. government, with commercial and academic proposal partners sharing costs on the rest.

The A&M System is the prime contractor for a team of world-class academic, commercial and nonprofit institutions that will bolster the nation’s domestic manufacturing and surge capacity. This highly integrated research and development team will use state-of-the-art processes to develop and test new vaccines and therapies for public health emergencies such as an outbreak of pandemic influenza.

The center will use rapid, nimble and flexible approaches to: • develop and manufacture vaccines to protect against pandemic influenza; • provide therapies in the event of chemical, biological, radiological, and nuclear threats; • perform advanced development, accelerating vaccines and other biosecurity products through preclinical and clinical development, leading to licensure; and • train the next generation of professionals in areas required to sustain this national capability, including process engineering, pharmaceutical manufacturing, veterinary sceinces, quality, and regulatory affairs.

The A&M System has a history of national service. System members are leaders in national research and education with a demonstrated commitment to applied life sciences research and developing commercial biopharmaceutical and national biosecurity solutions, particularly at Texas A&M University, the A&M System’s flagship institution, in the critical engineering disciplines required for this program.

Two engineering research teams win NSF EFRI grants totaling $4 million Two research teams led by Texas A&M Engineering faculty members have received National Science Foundation (NSF) grants through the Emerging Frontiers of Research and Innovation (EFRI) program. The grants were awarded to the team led by Richard J. Malak Jr., an assistant professor in the Department of Mechanical Engineering, and Arum Han, associate professor in the Department of Electrical and Computer Engineering, and total nearly $4 million.

Malak’s research team, which also incorporates faculty from aerospace engineering, computer science and engineering, and visualization, aims to discover new techniques for synthesizing complex 3-D structures from programmable, selffolding 2-D elements. The combined design theory and methods will address a class of design problems—structures made from programmable self-folding active material elements—for which no methods presently exist. If successful, the results of this research will constitute a substantial leap forward in engineering technology and knowledge, allowing engineers to design complex systems in fundamentally new ways.

Han’s research team will work to develop technologies for next-generation microalgae-based biofuel. Application of microfluidic lab-on-chip devices to photosynthetic microorganisms such as microalgae could rapidly reveal critical information needed for improving the production of transportation-grade hydrocarbons. Their proposed strategy is to transfer the valuable hydrocarbon synthesis pathway of the slow-growing alga Botryococcus braunii to faster-growing algae with commercial potential. B. braunii hydrocarbons are of particular value because they can be readily converted into petroleum-equivalent fuels. Han said the proposed research will have broad scientific impact because the microfluidic platforms will accelerate research and development across the broad area of biofuel and biomolecule production in a range of microbes, as well as training the next generation of microbial bioenergy engineers and scientists.

News New publication details future of process safety for academia, industry Substantial risk remains for serious industrial incidents that could cost property and lives, but effectively integrating science and engineering principles into academia and industry can help mitigate and even prevent these incidents, according to a publication released by the Mary Kay O’Connor Process Safety Center at Texas A&M. The publication, Process Safety Research Agenda for the 21st Century, is the product of a 2011 conference that was sponsored by the center and attracted a host of international authorities in the field of process safety to help develop a blueprint for the study and integration of process safety in academia and industry. With the goal of providing a deeper examination into the root causes of industrial incidents, the group set out to address the role of science and engineering in preventing these events, said M. Sam Mannan, director of the Mary Kay O’Connor Process Safety Center and the Mike O’Connor Chair I in the Artie McFerrin Department of Chemical Engineering. “This publication is the product of a unique gathering and the subsequent work of some of the top authorities in the world who are studying various aspects of process safety,” Mannan said. “It provides a roadmap that outlines the process safety research and needs that will be critical in the coming years.”

Texas A&M research team receives NSF grant for searchand-rescue UAVs Researchers and responders from The Texas A&M University System have received a grant from the National Science Foundation (NSF) to create a visual “common ground” between operators and responders who use micro and small, unmanned aerial vehicles (UAVs) for search and rescue. Following principles in how people know what other people are talking about in conversations, visual common ground will allow responders to easily express, using an iPad or other tablet, where they want the UAV to fly and what angle to examine collapsed structures.

The responders would also be able to review imagery and video while the UAV continues its mission rather than waiting for the UAV to land. Response professionals from the Texas A&M Engineering Extension Service (TEEX) Disaster Preparedness and Response Division will fly weekly at Disaster City with researchers from the Texas A&M Engineering Experiment Station’s Center for RobotAssisted Search and Rescue (CRASAR), speeding the development and refinement of the natural user interface.

The grant is the first direct partnering of emergency responders with university professors and researchers for UAV research. TEEX’s Bob McKee, agency chief for Texas Task Force 1, serves as a principal investigator with Robin Murphy, Texas A&M professor and CRASAR director.

The partnership leverages the capabilities of top academic researchers and the preparedness and response expertise of TEEX, all existing within the A&M System.

New technology could improve treatment for diabetes, other disorders For people suffering from diabetes and other hormonal disorders, staying healthy means staying vigilant; effective treatment requires periodic and precise doses of drugs throughout the day. Now, managing these disorders could become easier thanks to drug-delivery technology being developed by Zhengdong Cheng, associate professor in the Artie McFerrin Department of Chemical Engineering.

Cheng’s work explores a new method for manufacturing the tiny particles that once inside the bloodstream deliver drug treatments to targeted areas of the body.

Unlike previous models, Cheng’s drug-delivery particles could potentially administer periodic doses of the drug they contain throughout the day—something that has historically proven difficult for drug-delivery technology but if achieved could eliminate the need for a patient to self-administer multiple times. Although there is still work to be done before Cheng’s mechanism becomes a viable drug-delivery vehicle, preliminary results are promising, he says, noting that the particles have demonstrated the ability to deliver a payload with a system. Cheng says he plans to continue researching the model to further explore methods of controlling the oscillating effects in different environments as well as with different payloads.

News Civil engineering professor Myounggyu Won receives Best receives two-year, $400,000 DOE Student Paper Award award for wind energy research Moo-Hyun Kim, professor in the Zachry Department of Civil Engineering, received a twoyear, $400,000 research grant from the U.S. Department of Energy’s (DOE) U.S. Offshore Wind Technology Development Program. Kim will develop a dynamic mooring-anchor analysis program for a floating offshore wind turbine. The award was one of 41 offshore wind power R&D projects that received funding totaling $43 million as part of a coordinated federal strategy to put the nation’s wind resources to work and support innovation and jobs throughout the U.S. The projects represent investments in more than 160 universities, labs and businesses in 20 states, which will bring offshore wind to market in the Northeast, mid-Atlantic and Southeast.

Myounggyu Won, Ph.D. candidate in the Department of Computer Science and Engineering, received the Best Student Paper Award at the 9th IEEE International Conference on Embedded and Ubiquitous Computing, held in Melbourne, Australia. Won had two papers accepted: “Energy-Efficient and Robust Multicast Routing for Large-Scale Sensor Networks,” which received the Best Student Paper Award, and “Destination-Based Cut Detection in Wireless Sensor Networks.” In his winning paper, Won presents an energy-efficient and robust geographic multicast routing protocol for large-scale wireless sensor network deployments in realistic environments (e.g., characterized by obstructions, such as holes). His multicast protocol discovers near-optimal multicast routing paths given the restriction of possible complex topologies such as network holes. This protocol also ensures reliable and fast packet-loss recovery through its efficient topology generation.

Aerospace engineering Ph.D. student wins Immersive Visualization Competition Aerospace engineering Ph.D. candidate Shriram Jagannathan won first place in the university’s Immersive Visualization Center’s sixth annual competition. Students from a range of disciplines presented work ranging from virtual reality games to turbulent flows. Students created a visualization by using data of their choosing and were judged on visual appeal, scientific accuracy or artistic merit (as applicable), and verbal presentation. Jagannathan’s entry, “Visualization of Coherent Structures in Incompressible and Compressible Turbulent Flows,” focused on stereoscopic visualization of shocklets (highly compressed regions), vortices and high–Mach number regions in a compressible turbulent flow. The visualization yielded important physical insight. They showed, for example, that shocklets move much faster than the mean fluid motion and that regions of high Mach number tend to be more intermittent at high Reynolds number.

Project aims to remove space debris Low Earth Orbit is overcluttered with rogue objects and collision shrapnel that are a constant threat to spacecraft.

Experts say that a traditional satellite mission to go capture each object is not efficient enough to make an appreciable difference because of the high cost of orbit transfers. Daniele Mortari, professor in the Department of Aerospace Engineering, and his Ph.D. student Jonathan Missel are developing a new and creative mission structure that reinvents the way the problem is approached. The proposed mission, “TAMU Sweeper,” and the novel satellite design, “SlingSat,” capture and then eject each object through collisions that strongly reduce (or even eliminate) the need to burn fuel for rendezvous, and ejecting the debris mass keeps the craft light. In addition, the momentum exchanged in the capture and ejection of each object can be intelligently planned to act as free impulses for the satellite to transfer to the next object, in place of fuel. The free impulses from capture and ejection are both considered in trajectory optimization to maximize their effectiveness. Sling-Sat also exploits existing momentum to save fuel. Debris is captured at the ends of a spinning satellite. Adjustable arms control the angular rate to achieve a desired tangential ejection speed. Timing the release exacts the ejection angle. Through this process, debris can be redirected to burn up in the atmosphere or by lowering the perigee. The consequent drag increase will then reduce the debris lifetime.

Faculty Honors & Awards

Datta-Gupta elected to National Academy of Engineering Akhil Datta-Gupta, Regents Professor and L.F. Peterson ’36 Chair in the Harold Vance Department of Petroleum Engineering, has been elected a member of the The academy honors those who have made important and significant contributions to engineering theory and practice as well as unusual accomplishment in the pioneering of new fields of technology.

and two SPE Cedric K. Ferguson Certificates for the best peer-approved paper in 2000 and 2006. He has been named an SPE distinguished member, distinguished lecturer, distinguished author and outstanding technical editor.

Datta-Gupta was recognized “for developing the theory and practice of streamline simulation for fluid flow in heterogeneous reservoirs.”

In addition to his SPE awards, he received the AIME Rossitter W. Raymond award, received the Tenneco Meritorious Teaching Award from the Dwight Look College of Engineering at Texas A&M, and served as a member of the Polar Research Board of the National Academy of Sciences (2001–2004). He is also the recipient of the U.S. Department of Energy Award for Outstanding Contributions to Basic Research in Geosciences in 2008.

He is a coauthor of the SPE textbook Streamline Simulation: Theory and Practice.

3-D streamline simulation is widely considered as one of the major developments in petroleum reservoir simulation and performance forecasting in the last decade. The technology has been rapidly assimilated by the industry for highly detailed flow simulation, reservoir management, model calibration and uncertainty assessment.

With the advancement in high-resolution data acquisition and seismic technologies, geologic models now routinely consist of multimillion cells. This resulted in a widening gap between geologic modeling, flow simulation and uncertainty assessments. Streamline simulation has effectively bridged this gap. Datta-Gupta manages one of the most active industrial research consortia related to streamline simulation and its applications.

Among his numerous honors are the 2009 John Franklin Carll Award from the Society of Petroleum Engineers (SPE) for distinguished contribution in the application of engineering principles to petroleum development and recovery; the 2003 SPE Lester C. Uren Award for significant technical contributions in petroleum reservoir characterization and streamline-based flow simulation;

Datta-Gupta earned his master’s degree and Ph.D. from the University of Texas at Austin and his B.S. from the Indian School of Mines in Dhanbad, all in petroleum engineering.

With Datta-Gupta’s election, Texas A&M University now has 19 members of the National Academy of Engineering, 13 current faculty members and six emeritus.

Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer. Academy membership honors those who have made outstanding contributions to “engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature,” and to the “pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education.”
