DEAN’S MESSAGE It’s been an incredible year for the Samuel Ginn College of Engineering, one in which we have made key advances as Auburn University’s largest academic unit. Our enrollments continue to be strong, our research volume continues to place us among the top institutions in the nation, and we continue to move aggressively in modernizing and enlarging our facilities. In fact, we are moving through a period where our facilities are building on the same kind of impetus that we experienced a decade ago with the construction of the $150 million Shelby Center for Engineering Technology. We are now in the final stages of the renovation of one of our landmark buildings into the Gavin Engineering Research Laboratory, and in the beginning stages of constructing a state-of-the-art structural dynamics laboratory. At the same time, we are at the midpoint in the construction of the Brown-Kopel Engineering Student Achievement Center, which will serve the college as a recruiting center, a place where our corporate partners can meet, a central location where we can host our alumni and, most importantly, a place where we can engage our students in interactive teaching and cooperative learning experiences. Our unwavering goal is to provide the best student-centered engineering experience in the country. We continue to build on a well-established research presence, and have just established a center that addresses additive manufacturing – the National Center for Additive Manufacturing Excellence, which has been developed in collaboration with NASA. We are also partnering with ASTM International, NASA, EWI and the Manufacturing Technology Centre to establish the ASTM International Center of Excellence for Additive Manufacturing. Our thrust in cybersecurity will take a new and exciting direction as the McCrary Institute for Critical Infrastructure Protection and Cyber Systems becomes operational this year. As dean, I am excited about these facilities and programs, but even more excited about the tremendous surge we have experienced in bringing new faculty into our college. We could not have brought this new generation of teachers and researchers into the college without the solid foundation and world-class reputation of our veteran faculty members – and I find now that we have an exceptional faculty enlivened by a new generation of engineering talent that brings with them new ideas, new methods and new dreams. Auburn President Steven Leath has challenged the university community to “inspire, innovate and transform.” The Samuel Ginn College of Engineering believes in these touchpoints, and in taking the action necessary to meet and exceed these expectations. As you read this report, we hope you will see how our faculty is moving toward and beyond these goals as we seek to reach new levels of engagement with our students, our alumni and our partners in industry and government. Sincerely,
Christopher B. Roberts

OUT OF THIS WORLD Masatoshi Hirabayashi, assistant professor of aerospace engineering, joined an elite group of scientists and engineers whose contributions to planetary science have warranted an asteroid naming. Hirabayashi was honored with the asteroid naming at the “Asteroids, Comets, Meteors 2017” conference in Montevideo, Uruguay. Hirabayashi’s asteroid, 11471 Toshihirabayashi, was discovered on March 6, 1981, at the Siding Spring observatory in Australia by astronomer Schelte Bus. Hirabayashi’s work focuses on astronautics and geophysical modeling for small planetary bodies and planetary surface processes, specifically the dynamics and structure of these small bodies. He believes his study on the comet 67P/ Churyumov–Gerasimenko, which was published in Nature, was a large factor in the selection of his asteroid name. Hirabayashi’s Space Technology Application Research, or STAR, lab is collaborating with NASA and the Japan Aerospace Exploration Agency on missions that involve asteroids and other small bodies, such as the DART mission and the Hayabusa 2 mission. “In space missions, a better understanding of natural phenomena in space will help us develop innovative technologies and solve challenging problems,” Hirabayashi said. “I would like to conduct interdisciplinary research for critical space missions, such as asteroid mining and deflection.”

ENTREPRENEURIAL STUDENT HIGHLIGHTS ENGINEERS A team consisting of Auburn engineering students and alumni has hit the market with Tennibot, the world’s first autonomous tennis ball collector. By using advanced algorithms and computer vision technology, Tennibot is able to freely roam hard and clay courts as it identifies any dispersed tennis ball and places it into an attached ball bucket. Before players practice their slice serves and twisting backhands, they can access the Tennibot app on their phones to select the areas on the court that Tennibot will clear during their session. Tennibot Founder and CEO Haitham Eletrabi, a 2014 doctoral graduate in civil engineering, remembers his eureka moment that resulted out of frustration. “I was out hitting with a tennis ball machine when I realized I spend more time picking up balls than hitting them,” Eletrabi said. The Tennibot’s creative concept has brought success in numerous competitions, such as winning the grand prize in the Tennis Industry Association’s inaugural Tennis Industry Innovation Challenge. Tennibot was also awarded $40,000 from the Auburn Regional Alabama Launchpad competition for its ingenuity and marketability. In addition to Eletrabi, the Tennibot team is comprised of mechanical engineering alumnus Lincoln Wang, public relations alumna Kelsey Bixler and current mechanical engineering student David Wahlig. For more information, visit tennibot.com.

the system to help us look at more practical problems.” A research team led by Thurow has been awarded a $1.1 million grant from the National Science Foundation to develop a new, single-camera imaging system capable of capturing high-speed and 3-D measurements in practical flow fields.
A group of Auburn Engineering researchers is developing a new imaging system that could have wide-reaching impacts, ranging from health care to the aerospace industry.

“From blood flow through artificial heart valves to the mixing and combustion of fuel and air in a modern jet engine, many flows are both unsteady and three-dimensional,” said Brian Thurow, professor and chair of the Department of Aerospace Engineering. “Modern diagnostics used to study these flow fields are slow, two-dimensional, and in the case of multi-camera 3-D diagnostics, both expensive and complex. We are trying to simplify fundamental 3-D imaging technology into a more compact and economical hardware, while also increasing the speed of
In recent years, Thurow’s lab developed a prototype that has been demonstrated as a simple, robust and effective 3-D imaging system. The grant is helping researchers to develop the hardware and software of the technology, which allows them to capture all the information they need in one snapshot, using just one piece of equipment. “In one click of the shutter, can you get all of the information about what’s happening in three dimensions? The unique piece of what we’re developing is that we don’t have to have hundreds of cameras looking at an experiment at one time, and we don’t have to move the cameras around to a number of different positions,” Thurow said. “We can do it all in a simple, compact hardware, which will also allow the system to be optimized for various facilities and techniques.”
Aerospace Engineering, Stanley Reeves of the Department of Electrical and Computer Engineering, and Pavlos Vlachos of the Purdue University School of Mechanical Engineering.
Thurow said the technology allows the team to expand their research beyond aerospace to other areas, including biomedical engineering and cardiovascular fluid mechanics. “Dr. Thurow and I are looking at ways to apply his technology in biomedical engineering,” said Vrishank Raghav, assistant professor of aerospace engineering. “No one has done that before. It’s a newer technology, so we are trying to incorporate these ideas into understanding cardiovascular diseases.” Raghav’s primary focus is prosthetic valve design, essentially prosthetic or artificial heart valves that are implanted into patients with a failing heart valve. Natural wear and tear on the heart leads to calcium deposits and damage to valves, which can begin to malfunction. “Younger patients are usually able to undergo open heart surgery, but older patients usually cannot withstand it,” Raghav explained. “There is a new technology that is not as invasive, called transcatheter valve replacement, where doctors make an incision in the thigh or groin area, and snake a catheter up to the heart and replace the valve. While I was at Georgia Tech previously, I began collaborating with Dr. Thurow to apply his technology
to improve the valve design for this transcatheter approach.” Raghav said that optical access is extremely limited when replicating the flow in the heart using a bench-top system, since they don’t have multiple points of entry like they do in the case of some aerodynamic experiments in aerospace engineering. “This technique offers significant advantage because it’s also a single-camera technique, where other techniques use four. We can measure volumetric flows or 3-D flow fields and can take multiple snapshots of the velocity field around the heart valve within a single cardiac cycle, or one heartbeat,” he said. Thurow said the system will have an immediate impact on the understanding and treatment of cardio/cerebrovascular diseases; the understanding and modeling of non-reacting compressible flow fields associated with high-speed vehicles; and the understanding and design of stable and efficient combustion processes. Long term, the technology will support collaborative research activities at both Auburn and Purdue University.
“At Auburn, biomedical fluid dynamics, unsteady 3-D rotating flows and combustion instability are emerging topics being led by Vrishank Raghav and David Scarborough,” Thurow said. “Our counterparts at Purdue have a track record of applying advanced diagnostics to high-impact problems and are well established in their respective fields. There is this nice synergy between what they’re doing and what we’re doing. We are able to focus on the instrumentation and hardware development, and then the applications will push out through the work of our colleagues at Purdue. The collaboration is mutually beneficial.”

FUELING
AN ALTERNATIVE FUTURE Making bio-sourced fuels part of mainstream travel is an uphill road, but it’s one Auburn’s Center for Bioenergy and Bioproducts is prepared to take B Y

Sushil Adhikari was born and raised in Nepal, a landlocked country with no access to fossil fuel-sourced energy. Hydraulic power still provides much of the country’s energy needs, but large swaths of homes have no electricity.
from nature that are converted to fuel through pyrolysis and gasification. These fuels could supplement and — in the distant future — help to replace gasoline, diesel fuel and jet fuel that is currently derived from slowly declining fossil fuel supplies that have largely powered the U.S. for the past century.
Growing up in that environment shaped Adhikari’s future.
Accomplishing that goal requires collaboration with a group of specialists from across the Auburn campus, including researchers in engineering, agriculture and forestry and wildlife sciences.
“A lot of people are dependent on firewood stoves,” he said of his native country. “Not every place has electricity. So I was just fascinated about alternative energy.” Adhikari, director of the Center for Bioenergy and Bioproducts and Alumni Professor of Biosystems Engineering, aims to devise increasingly efficient methods of producing fuels from biomass — trees, grasses, algae and other resources
Biofuels and bioproducts are intertwined economically, Adhikari said. Revenue from the sale of bioproducts, which now have a high profit margin, can be diverted to reduce the cost of biofuels. And the bioproducts industry is booming, he said.
For instance, Coca-Cola has kicked off its plan to produce all its plastic bottles from bioresources, Lego is committed to construct its plastic bricks from bio-sourced materials and Ford is using soybean-based materials to make auto interior boards and car parts. Alabama is home to a forest production and processing industry that contributes more than $2 billion to the state economy, making it a prime candidate to lead the growth of a bio-based economy. “The forest industry in the South has a long history. It is sustainable,” Adhikari said. “People have been growing trees and selling to the pulp and timber industries for a long time. All we’re trying to do is create a different market.”
PRIORITIZING PROGRESS Adhikari said he cannot overstate the crucial role of biofuels in creating a cleaner, higher quality alternative to fossil fuels, but the topic seldom surfaces beyond the bioengineering field. There are major challenges. While the Department of Energy, the Department of Agriculture, the Electric Power Research Institute, Alabama Power and the university provide ongoing funding for research, Adhikari says any further biofuel advancement relies largely on the state of the economy and the political landscape. During the 1970s, the urgent need for alternative energy sources was front and center as two devastating gas crises resulted in soaring prices. As the U.S. government rationed gas, lines of cars wrapped around city blocks as drivers waited hours just to make it to the pump. In that perilous time, the idea of biofuels was “tossed in,” Adhikari said. Government funding to science-centered institutions, including Auburn, was increased to support research and production, and researchers jumped at the chance to get their fuel out there. But then, the crisis subsided, gas became affordable, and seemingly everyone forgot about the promise of biofuels. Funding dissipated. It happened again in 2008, when gasoline prices rose to more than $4 per gallon. But that crisis ended, too, and since then, the average price per gallon has hovered around $2.50. In the summer of 2018, gas prices rose to a four-year seasonal high, with vacationers doling out $2.70 per gallon. It’s an unpredictable scenario, Adhikari said. Garnering attention

from organizations and institutions that could lend enough funding to create longstanding biofuel production would require nothing less than another national crisis. Biofuels cost about double the price per gallon of gas. They’re unable to compete. Adhikari uses the word “cost” not in terms of dollars, but as a viable way of solving long-term problems and reversing a century’s worth of damage. “Price is one thing, but what are the other benefits that biofuel in general brings to society?” Adhikari asked. “What’s the benefit of getting fuels from this alternative energy source rather than digging out the coal and other fossil fuels? What is the price of introducing carbon dioxide, greenhouse gases? What are the benefits of having a local biorefinery in a rural area like Selma in west Alabama? What is that going to bring to the community over there? Those are the impacts.” He likens the difference between gasoline and biofuel to a familiar activity: shopping, comparing massive discount stores that deal in high volume, low-value products — like Walmart — to upscale stores that sell high-value, low-volume products, such as Publix. The products are similar. The shopping experience and the quality of the product are worlds apart. That model applies to the comparison of biofuels and fossil fuels. All that is needed is to focus on research and development. How does that model apply to biofuels? “One would be the perception — people understanding the importance of biofuels and how they affect the environment by lowering CO2 emissions,” he said. “The other way is to keep focusing on research and development. There is a road to go down, but we are not there yet.”
A MULTIDISCIPLINARY QUEST Spreading awareness of biofuels to a large segment of the population necessitates an enormous amount of study from top experts in multiple fields. Fortunately, Auburn has them in abundance. The Center for Bioenergy and Bioproducts research is based on an integrative approach that culls findings from multiple schools, colleges and departments across the Auburn campus. Mario Eden, Department of Chemical Engineering chair and the Joe T. and Billie Carole McMillan Professor, is one of the center’s founding members. After securing the university’s first NSF-IGERT project, Eden worked with 30 doctoral students from engineering, sciences and mathematics, agriculture and forestry to study biomass-based fuels and products. “This is a highly complex and multi-faceted problem that needs innovation and advances in myriad areas, and thus demands an interdisciplinary approach,” he said. “It is important for everyone in the supply chain to understand the capabilities of each step and how it impacts the overall result.” Maria Auad, professor of chemical engineering and director of the Center for Polymer and Advanced Composites, is part of the interdisciplinary team. “It is a new approach,” she said of the integrated research. “Looking for ways to create sustainable materials offers an enormous opportunity to share a common interest but also pulls all the ideas from completely different points of view. The opportunity was to convert these biofuels into products. My background is in plastics, and I am using these bio-oils to produce resin. There is such a great contribution from all these sectors.”
The most notable event to impact this effort is the recent launch of a new sustainable biomaterials and packaging degree at Auburn’s School of Forestry and Wildlife Sciences. Set to begin in the fall, it is a promising turn of events that may lead to more funding for and awareness of biofuels.
A NICHE MARKET Adhikari emphasizes that biofuels alone won’t conquer all the transportation challenges brought on by the decrease in fossil fuel sources. He foresees an energy future that utilizes multiple technologies, with some drivers in electric cars, others still dependent on gasoline or hybrid energy, and a growing number of
vehicles and aircraft running solely on biofuels. Getting planes off the ground is a prime example of biofuels’ possible niche market. “It would be extremely hard for you to think about flying an airplane with just solar power or batteries instead of jet fuel, which biofuel can replace,” he said. That is just one scenario in which biofuel will be able to step in to fulfill a need that cannot be aided by other alternative energy source. Biofuel is among myriad sources that have emerged as researchers look to supplement fossil fuels, Adhikari said, but “this will be an extremely significant one.”

“We need to break the traditional chemical process engineering paradigm,” Tatarchuk said. “The need is a 100 barrel per day plant — not a 100,000 barrel plant — but a 100 barrel a day plant at a significant lower capital expenditure.”
Hulking oil refineries dot the coastline of the Gulf of Mexico, stretching from Texas to Alabama, with many of these facilities churning out more than 100,000 barrels of product per day. Refining crude oil is a tried and true method of energy production, and it has helped put the U.S. on a path toward energy independence. But it’s not without drawbacks. Operating an oil refinery is tremendously capital intensive, requiring tens of billions of dollars, and the facility must be strategically located near the supply chain and distribution infrastructure. “All of those factors don’t always align, and the answer is we waste a lot of energy,” said Bruce Tatarchuk, the Charles E. Gavin III Professor of Chemical Engineering.
By addressing fundamental science and technology barriers, Auburn researchers are identifying ways to economically produce and utilize small and otherwise underutilized energy sources in an environmentally beneficial manner.

Because large-scale operations such as oil refineries dominate the energy industry, many smaller and more isolated energy sources are underutilized or, in many cases, essentially stranded. Tatarchuk and his team of researchers in Auburn’s Institute for Scalable Energy Conversion Science and Technology are aiming to take advantage of these energy resources by creating smaller scale solutions.
Realizing the importance of research in this area, Auburn University established a cluster hire area for scalable energy conversion science and technology and committed 12 new faculty hires across a wide range of disciplines, including agriculture, chemistry, engineering and forestry. By addressing fundamental science and technology barriers, Auburn researchers are identifying ways to economically produce and utilize small and otherwise underutilized energy sources in an environmentally beneficial manner. Some of these candidate energy sources include agricultural and forest biomass, land fill gas, anaerobic digester gas, food wastes, coal wastes and a large number of small oil and gas wells that populate Alabama and many other areas of the U.S. In talking about scalable energy solutions, Tatarchuk likes to show a satellite photo of the U.S. at night. As one would expect, cities such as New York and Chicago light up the night sky. But so do sparsely
populated areas in North Dakota and Texas. The associated light comes from smaller oil and natural gas wells flaring gas in the Bakken and Eagle Ford shale formations. Tatarchuk says that 20 to 30 percent of the gas brought to the surface at these wells is flared, or burned off and essentially wasted. It is far preferable to develop a system that can capture that wasted energy. “For a number of years, we have been studying ways to make chemical conversion plants smaller and able to be mounted so they could go on individual wellheads,” Tatarchuk said. “We have been very active in this area and pretty successful.” Although flaring gas is the preferred method across the industry, many energy sources often vent the gas, or release it directly into Earth’s atmosphere. “Much of the gas around the country — whether it’s landfill sites, emissions from oil and gas, wastewater treatment facilities or others — much of that is being vented, and that methane is a major greenhouse gas contributor,” Tatarchuk said.
A big culprit is landfills, of which there are 52 in Alabama. A few have started burning waste and selling the steam to other entities, but a large amount of methane is still vented into the atmosphere. “Some landfills will clean this gas up and run it though an engine perhaps to make electricity. Most don’t,” Tatarchuk said. That’s where Auburn’s work comes in. By developing scalable chemical operations, Auburn researchers are aiming to produce standardized modules that can tap into these underutilized resources and produce usable energy units in a cost-effective manner while also benefitting the environment. Auburn’s expertise and track record in this area has not gone unnoticed. In 2016, the Department of Energy established the 10th Manufacturing USA Institute, the $70 million Rapid Advancement in Process Intensification Deployment, or RAPID, Institute.
productivity and energy efficiency through manufacturing processes in industries, such as oil and gas, pulp and paper and various domestic chemical manufacturing enterprises. Auburn is a founding member of RAPID and one of only four universities on the executive governing board and the technical advisory board, according to Tatarchuk, who represents Auburn on both boards.
“Auburn University’s administration is putting unprecedented resources into research, so this is a very exciting time at Auburn,” Tatarchuk said. “Our Institute for Scalable Energy Conversion Science and Technology is primed for a big future in this area, and we believe our innovative research will address pressing societal needs in energy security, the environment and economic development.”

of the Brown-Kopel Engineering Student Achievement Center is made possible thanks to a $30 million gift from the Browns, part of an overall $57 million gift that was announced in April 2015 at the Because This is Auburn – A Campaign for Auburn University kickoff event. The 142,000-square-foot BrownKopel Engineering Student Achievement Center will consolidate a multitude of student support services into one facility. This building will house resources for students from freshman year through graduation, including recruiting and scholarships; academic advising; tutoring and learning; professional development and corporate relations; a design and innovation center; and more than 40 collaborative study areas. “This facility will allow us to be capable of significantly transforming the personal and professional successes of tomorrow’s Auburn
engineers by providing students with the highest level of hands-on experiences and academic support throughout their college experience,” said Christopher B. Roberts, dean of engineering. “Redefining engineering education in a changing world and training engineers inside and outside the classroom is a vital part of our vision. This facility will enable the college to build the infrastructure to make this a reality.” Located in the heart of campus, this facility will specifically address students’ professional and academic needs, providing one of the most comprehensive, active-learning environments in the country. In cohesion with the college’s vision to provide the best student-centered engineering educational experience in America, the center will also create greater opportunities for collaboration among faculty members and students, creating a sense of home within the engineering campus.

The first floor of the building will include a design and innovation center, which will consist of student-maker spaces, laboratories, shops, project incubators, study rooms, a flexible classroom, computer labs and more, while also serving as the home for engineering student organizations. The second floor will house a tutoring and learning center, academic advising center, student recruitment center, professional development and corporate relations center, the Engineering Academic Excellence Program for underrepresented students and offices for support staff. The third floor will incorporate ample, spacious student study areas with large-group and small-group study rooms, two large flexible classrooms,
boardrooms, conference rooms and a grand hall, all outfitted with the latest smart technologies. In addition to the construction of the Brown-Kopel Engineering Student Achievement Center, the college has renovated the former Textile Building — now the Gavin Engineering Research Laboratory — thanks to a generous $10.5 million gift from Charles Gavin and his late wife, Carol Ann. The renovation of the Gavin Laboratory allowed the college to demolish the Engineering Shops and L Building, and create the Carol Ann Gavin Garden. The Textile Building was originally constructed in 1929 to prepare future engineers for the textile industry,
and it has served as a vital component to economic development in the region and state for more than eight decades. An additive manufacturing facility will be incorporated into the building renovation to allow students to gain experience with emerging fabrication technology, as well as the new Center for Polymer and Advanced Composites to continue the college’s research in this area and to meet industry needs. The renovated structure will include traditional research laboratories, as well as a facility for the Nuclear Power Generations Systems Program, a new wind tunnel system, a pulp and paper pilot machine, a series of
hands-on student project areas and collaborative meeting spaces. The south entrance of the Gavin Engineering Research Laboratory will also be renovated to allow students more convenient entry to the building when coming from the heart of campus, while also providing access to the Brown-Kopel Engineering Student Achievement Center. “Charles and Carol Ann’s generous gift enabled us to retrofit the new laboratory with advanced technologies to serve students for the next 80 years,” Roberts said. “This is very important as we continue to provide meaningful, hands-on experiences to students.” Broun Hall, the home of the Department of Electrical and Computer Engineering, has been renovated to include the Davidson Pavilion, which has transformed the area most used by students and includes a new main entrance that allows natural light into the first two floors. The renovation was made possible thanks to a $5 million gift from Dorothy Davidson in honor of her late husband Julian, a 1950 electrical engineering graduate and defense industry pioneer. “We will make the student experience the best it can be and increase the value of an Auburn degree, and this beautiful new addition to campus helps us achieve those goals,” said Auburn University President Steven Leath. “This renovation provides our students and future generations with the tools and environment to thrive, collaborate and innovate.” These facilities upgrades come on the heels of more than $173 million in construction over the past 20 years.

Automobile collisions resulted in more than 37,000 fatalities in the United States in 2017, according to recent projections from the National Highway Traffic Safety Administration. Is it possible to predict when and where accidents will happen? Can the number of yearly traffic fatalities and injuries be reduced to zero? Civil engineering faculty members at Auburn University are using big data and advanced technologies to answer these questions through their research in transportation engineering.
ANALYZING DRIVER BEHAVIOR Unprecedented amounts of data are being generated from sources such as ride-sharing services and smartphone applications. With information becoming more prevalent and available than ever before, the resultant mountains of data can be mined to better forecast travel behavior patterns. Managing the transportation system involves long-range planning, and Associate Professor Jeffrey LaMondia is confident that these databases will revolutionize the
If each state can identify two locations per year to implement our suggested countermeasures, there will be a significant reduction of fatalities.
process. He’s working to help shape the Next Generation Travel Behavior Data Initiative for the Federal Highway Administration to better understand how, why, when and where people travel. “It’s the first of its kind that we’re pushing forward,” LaMondia said. “I’m working closely with a number of states and private industries to collect and fuse data from a variety of public and private sources together.” The objectives of the initiative are to collect, process, estimate and report national state and local travel behavior on an annual basis. With enough data, patterns begin to develop that can be applied to transportation modeling, planning and policy. It’s the ability to predict trouble before it happens, such as maintenance issues and traffic congestion, that can make our streets safer for all users. “It’s extremely probability based,” LaMondia said. “We use non-deterministic methods to statistically identify whether you might have a high possibility of an incident happening, kind of like a red flag indicating that something may be wrong.”
38
Samuel Ginn College of Engineering
LaMondia is also teaching a data analytics course that blends the fields of mathematics, computer science, statistics and civil engineering. This newly offered class gives students the skills and tools necessary to understand patterns, discover relationships and develop predictions based on these data sets. “I come at it from a transportation angle, but we use different engineering examples in the class,” LaMondia said. “It’s really focused on modeling and simulating using these giant data sets. From structural equation modeling to neural network analyses, there’s so much information yet to be discovered that’s relevant to all fields of engineering.” This background in data science will help future transportation planners allocate the necessary resources to select safe and efficient infrastructure advancements to meet the changing needs of roadway users.
PRIORITIZING INTERVENTIONS Highway work zones present scenarios for traffic crashes that might not occur otherwise. Rod Turochy, the James M. Hunnicutt Professor of Traffic Engineering and director of the Alabama Technology Transfer Center, is investigating the severity of work zone-related crashes and the relationships between their severity and other variables. “We encounter work zones on a regular basis, and I only see that increasing,” Turochy said. “Most of today’s system is due for major
replacements and managing these work zones in the future will be imperative.” Turochy has developed a database of work zone related crashes in Alabama for the past 10 years that includes details from police reports, traffic control inspector reports, and supporting documentation from contractors. “We’re currently in the process of mining that database to find information that we can use to better design work zones and traffic control,” Turochy said. “We anticipate that this information will enable us to make some decisions to better operate these areas and reduce the frequency and severity of crashes.”
PINPOINTING THE FOCUS Huaguo Zhou, professor of transportation engineering, is leveraging datasets to create mathematical models that can predict the risk of wrong-way drivers entering the freeway at exit ramps. He is working with students to identify and monitor individual high-risk locations in Alabama. New data analysis technology can enable us to reconsider the assumptions about wrong-way collisions, according to Zhou. “There have been several research statements that wrong-way crashes are totally random, but we have found that high-risk locations exist. Instead of putting a camera at each
possible location, we can develop a model to select sites and then verify the model using field data,” Zhou said. “We hope this model can be used nationwide. Although wrong-way driving crashes are rare, they are severe. If each state can identify two locations per year to implement our suggested countermeasures, there will be a significant reduction of fatalities.” Over the past five years, Zhou has been working with the American Traffic Safety Services Association to develop advanced traffic control devices and intelligent transportation technologies to reduce severe and fatal crashes, including wrongway driving, roadway departure and work zone intrusion crashes. Five case study booklets have been published as a result of this work, one of which addresses the impact of connected and automated vehicles on transportation infrastructures and traffic control devices — one of the earliest publications of its kind to help agencies prepare for accommodating future transportation technologies. Zhou is also collaborating with Turochy on a project to improve geometric design practices for rural highway intersections using the Naturalistic Driving Study Database. Acquiring data from the nationally funded project, the researchers have access to information from instrumented cars around the country to address the role of driver performance and behavior in traffic
safety. The Department of Civil Engineering recently purchased a mini-driving simulator to enhance classroom teaching and assess the risk of poor driver behaviors. “We’re trying to improve the safety and efficiency of the system, mainly in areas of highway safety analyses and traffic operations,” Turochy said. “There’s all kinds of data being collected, from vehicle movement to looking at what the driver is doing and capturing potential distraction issues. Access to this data gives us the opportunity to really see what’s going on from a driver behavior perspective and determine what drivers are responding to.”
With this information, Turochy and Zhou can uncover and evaluate elements that may contribute to crashes at intersections and determine to what extent driver behavior, road conditions and street signs play a role. The information will support the development of alterations to roadway geometry, signs and pavement markings that can prevent traffic collisions and injuries. “One of the reasons I was drawn to transportation engineering is because it impacts almost everyone every day,” Turochy said. “If you leave your house, you’re going to be affected by the things that we do at Auburn.”

CULTIVATING
COMPUTATIONAL THINKERS Through NSF CAREER award, Jakita Thomas empowers the next generation of women in STEM B Y
T E R I
G R E E N E
2017-18 Dean’s Report

Auburn Engineering faculty member Jakita Thomas’ passion project has been years in the making. It began with 20 sixth-grade African-American girls who lived throughout metro Atlanta, some from inner-city sections, some from working-class families and others from affluent neighborhoods. These girls on the verge of entering their teenage years had little knowledge of the field of computing and no knowledge of the workings of algorithms. Thomas’ mission: put them at the starting line with Scratch, the most basic of video game-creation platforms, and lead them through the process of algorithmic thinking via one of their favorite pastimes. Now, the girls would become more than avid consumers of video games. They would be creators, armed with enough knowledge to venture into the cutting-edge world of virtual reality with systems including Oculus.
It’s helping students to see that game design and gaming can be a tool to create social change and to create changes in the way people experience and understand the world. From the outset, Thomas suspected the project would outgrow its initial aims. Three years later, all participants were still on board, ready for more immersion. She applied for a no-cost extension of her NSF CAREER Award to continue to track what would happen in the two years that followed. The findings of this complex longitudinal study could become a working model to increase access to the STEM fields’ underserved populations, Thomas said. The results could shift paradigms.
In the past five years, Supporting Computational Algorithmic Thinking, or SCAT, has allowed Thomas, the Philpott-WestPoint Stevens Associate Professor of Computer Science and Software Engineering, to collect data on how the girls perceive themselves as game designers and critical thinkers. The project aims to shatter barriers and assumptions. As a black woman in engineering, Thomas is acutely aware that she is one of a handful in her field. The girls she has been tracking are oblivious to any such statistics. “Most of my SCAT scholars may not even know that black women are heavily underrepresented in computer science,” Thomas said, citing the most recent Computer Research Association Taulbee Survey. It showed that black women received three percent of the bachelor’s degrees in computer science awarded in the United States in 2016 – and that was a drop from the previous year, in which that group received four percent of those degrees. “The numbers have been single-digit for years and years. And if you look at Native American women and Latina women, it’s the same,” she said. “It’s abysmal.” To recruit her first scholars for a yearlong pilot study, Thomas leveraged organizations including Boys and Girls Clubs, black churches and teachers. They found dozens of girls and their parents who were up to the challenge. That pilot study yielded such positive results
– though they knew they were in a limited program, some girls in the pilot program begged to be allowed to continue – that Thomas set out to begin her three-year study in earnest. The 20 sixth-grade girls who entered the now five-year-old SCAT program will soon enter 11th grade. They remain devoted to their progress, continuing to meet with Thomas monthly. Parents were enthusiastic to enroll their daughters. Tarenia Carthan saw SCAT as an opportunity to open new doors in tech for her daughter, Asia, and expand her knowledge of the field. “When she asks for rewards, she always wants video game cards. So I decided to find her a program that would put her on the other side of it, not just to play them but to actually create them,” Carthan said. Asia was game for it. “It’s a really exciting experience because you get to know about working with other people,” Asia said, adding that she became an expert in the Scratch video game creation platform and its algorithm, something one of her teachers at school refers to often. “What he talks about, I already know, so I have an advantage. It’s actually more fun than work.” In one of their latest projects, the scholars created digital comic books in which a young, black woman is cast in the role of superhero. Then, they put those superheroes in motion, making them the lead characters in their video games. Thomas said it was notable that those superheroes were not all based on the characteristics of the girls creating them. Several scholars created a united front of sister superheroes.
That speaks to the scholars’ level of cooperation, a critical component in the study. Thomas allowed the girls to form groups, with one caveat: they could not team up with girls they already knew from school or their neighborhoods. They were experiencing teamwork and cooperation, many of them for the first time. “They formed a kind of sisterhood around creating video games,” Thomas said.
SCAFFOLDS OF LEARNING The scholars were immersed in a cognitive-apprenticeship environment, structured on the educational scaffolding technique. For the first two years, an African-American computer science professor facilitated the group and modeled the way the girls needed to approach the learning process. Then, a group of undergraduate students — also black women — joined in, providing “just-in-time” scaffolding, catching the girls whenever they got stuck in the process, providing subtle pushes to help them along. In the final learning stage, novices who picked up the knowledge at an accelerated pace stepped in to help, or scaffold, their fellow scholars. “We ended up designing this extremely intersectional learning environment that spoke strongly to the needs of these girls,” Thomas said. “As black girls and as black women, we experience the world through a different lens because we experience multiple ‘isms’ simultaneously. We might experience racism, sexism and classism. There are a lot of different ‘isms’ that can’t be broken apart because our experience is that they’re happening at the same time.”
Thomas is thrilled that the games the girls are designing address social issues. That’s echoed in a class she has taught for the last two fall semesters at Auburn: Game Design for Social Change. “It’s helping students to see that game design and gaming can be a tool to create social change and to create changes in the way people experience and understand the world,” she said. “In video-game speak, that addictiveness or that playing as hours pass by is called flow. So if you can get somebody to enter a state of flow and at the same time help them to shift their perspective of how they see, respond to or understand the world, that’s amazing to me.” At the end of each middle school year, the SCAT scholars completed a questionnaire about their learning experience. “They were describing more and more these situations where they were using the things that they learned in SCAT in other contexts. Things like, ‘I taught my Girl Scout troop how to design video games,’ or, ‘I put together a presentation at my school about how to use Scratch because I already knew how to do it.’ I thought, ‘Oh, wow, it would be cool to see if we could more formally develop that capability in them.’” The girls led summer computer game sessions for younger kids, formulating their own lesson plans, then de-briefing with one another to analyze more effective approaches to teaching. Auburn doctoral student Rachelle Minor left a long, boring summer internship as a software tester and joined Thomas. She wanted to learn about non-programming computing fields. She liked working with kids.
It became so much more than an internship. Now, Minor is gauging how the subjects’ perceptions of themselves have shifted over time, using data from the study, but also drawing from the work of psychologist Albert Bandura’s work in social learning and self-efficacy. “After initially joining, I had no idea how impactful this program would be, not only for Dr. Thomas but for the SCAT scholars, their parents, the community, student researchers and co-facilitators, and for the expansion of the knowledge base in general, especially in STEM education,” Minor said. Once strictly consumers of video games, the girls are now designers and educators as well and continue to build on their knowledge and experience. Thomas said parents consistently tell her, “I had no idea my child could do that.” Yolanda Wright-Udoh enrolled her daughter, Nubia, in the program. “Since technology and jobs are ever-changing, it was definitely to her benefit to have been exposed to writing programs,” Wright-Udoh said. “It seems that’s where our future is leading, so she would
definitely have an edge in just being exposed to it, even if she doesn’t go into creating video games.” Nubia, at first reluctant, is now enthusiastic. “It helped me have a different view on thinking,” Nubia said. “I’d never heard the word algorithm before this program, and all the processes involved with it. I feel pretty awesome about learning it.” The ongoing goal is to encourage young African-American women to pursue computer science, software engineering and other STEM fields by shattering barriers and assumptions and sending a group of intensely trained and enthusiastic students into a realm where they have always been underrepresented. As they embark on their final years of high school, all the project’s scholars plan to attend college, and most of them intend to go into STEM fields, Thomas said. “How generalizable will the findings end up being? I don’t know,” Thomas said. “But I will be able to say, very clearly, that this particular young woman was impacted in this way because of something that happened here. Dots will be able to be connected, and that’s something that has been missing in the field.”

ATTACK OF THE CLONES
Electrical and computer engineering researcher seeks to combat cloning within global electronics supply chain B Y

Electronic cloning — whether it’s duplicating a printed circuit board or copying the electronics in a network router — is a significant and complex problem that is plaguing the global electronics supply chain. Cloned products with inferior quality parts or counterfeit components that make it through the supply chain and land in the hands of consumers may not be as reliable as the product with authentic parts. Such products may not even work. Or it may work just as well as the

For instance, a hacker who has control over a cloned router can intercept or redirect communications on the network. A car with cloned parts may not start. Or cloned devices that connect to an engine control unit may give a hijacker access to a car’s brakes and steering.

“While there appear to be no published reports of injury or hacking related to this cloning, the risks are bigger today because more of the systems we interact with daily are connected to the internet,” said Ujjwal Guin, an assistant professor in the Department of Electrical and Computer Engineering. “Cloned hardware may lack the security modules intended to protect such devices, and so it may open up the unsuspecting user to cyberattack.” Predictions from Gartner, a research and advisory company, and Cisco’s Internet Business Solutions Group, claim there will be 20-50 billion devices connected to the internet by 2020, further complicating the “internet of things.” Without solutions such as those being developed by Guin and others at Auburn University, the global epidemic of cloned systems will only worsen. “As the number of IoT devices grows, everyone should become more aware of the dangers that cloned products pose,” said Guin. Even if just 1 percent of those 50 billion connected devices were clones, harboring malicious hardware or software, that’s 500 million susceptible devices. Unfortunately, the battle against cloning and counterfeiting is much more complicated than it used to be. In earlier times, counterfeiters would simply repackage old or inferior components and sell them as if they were new, but these knockoffs had poor reliability. These days, cloned electronics are very sophisticated and potentially more nefarious.
Guin said the counterfeiters make their own components, boards and systems from scratch and then package them into superficially similar products. The clones may be less reliable than the genuine product, having never undergone rigorous testing. In addition, they may also host unwanted or even malicious software, firmware or hardware and the consumer may not know the difference. The growing practice of counterfeiting and cloning of electronics is destructive to the global supply chain, companies and consumers. The International Chamber of Commerce estimated that trade in counterfeit and cloned products — including non-electronic products such as designer handbags — amounted to $650 billion globally in 2011. A 2017 report commissioned by the ICC’s Business Action to Stop Counterfeiting and Piracy and the International Trademark Association estimated the wider social and economic impact on displaced economic activity, investment, public fiscal losses and criminal enforcement could reach an estimated $1.9 trillion by 2022. The negative impacts of counterfeiting and piracy — the unauthorized use or reproduction of another’s work — are projected to drain $4.2 trillion from the global economy and risk 5.4 million legitimate jobs by 2022, according to the report. “Cloned electronics are a great threat, even if the device is purchased in the United States,” said Jubayer Mahmod, a graduate
research assistant under Guin. “The electronic supply chain is quite complicated nowadays. Therefore, it is difficult to ensure the integrity of the parts and the devices. Internet-connected devices, like modems and phones, could lead to much more serious threats than just reliability problems. Cloning, along with hardware/software level malicious modifications, can make people vulnerable to hacking.” Such a gloomy outlook is only darkened by the fact that nobody really knows the true scale of cloning in the electronics realm. Cloners themselves are a clandestine group. Plus, adequate detection measures don’t really exist in the global supply chain. Guin wants to change that. His research is focused on developing solutions to detect counterfeit integrated circuits and cloned systems. By discovering these items in the supply chain, Guin seeks to prevent them from getting into electronic products before they are sold around the globe. Whatever the true size of the cloned electronics market, Guin and
fellow researchers at the University of Florida firmly believe it is growing, simply based on their work with SMT Corp., a Connecticutbased electronic parts supplier whose labs specialize in identifying cloned and counterfeited components in global supply chains. “Among the trends contributing to the growth of cloning are more-sophisticated imaging and analysis tools and the spread of contract manufacturing, a business model in which the companies that design chips and systems outsource their fabrication,” Guin said. “As design files are passed back and forth between the designer and the contractor, cloners will exploit any crack in security to get those files. Once a cloner succeeds in fabricating credible copies, the ubiquity of online sales makes it easy for the sellers to hide their identities and attract bargain-minded customers.” Guin’s research is part of the Charles D. McCrary Institute for Critical Infrastructure Protection and Cyber Systems at Auburn. “The primary objective of the McCrary Institute is to ensure security
for our critical infrastructure,” said Guin. “Infiltration of compromised electronics in our critical infrastructure will be catastrophic. An adversary can disable an infrastructure when they want.” Simply, Guin said his research is about trust. There is currently very limited trust in integrated systems manufactured outside the United States. However, establishing trust throughout the global supply chain should allow consumers to confidently purchase and use reliable electronic systems, no matter where production occurs. “Trust is a big part of combating this intricate problem,” said Mahmod. “A well-planned supply chain should improve consumers’ freedom of buying an electronic device.” With funding from the National Science Foundation, Guin’s latest project focuses on designing a
secure logic locking technique to enable protection against untrusted integrated circuits manufacturing. “Due to the prohibitive costs of semiconductor manufacturing, most computer chip design companies outsource their production to offshore foundries. As many of these chips may be manufactured in environments of limited trust, problems of the piracy of intellectual property and the overproduction of integrated circuits have emerged in recent years,” he wrote. Guin said research like his in addressing clones in the critical infrastructures is in the nascent phase and would benefit from additional support from government and industry. Now is a crucial time for such work as advance reverse engineering techniques are making cloning easy and low-cost electronic products are in high demand.

Samuel Ginn College of Engineering
The program offers affordable online degree offerings in eight engineering disciplines that will increase professional opportunities, and provide that stepping stone needed to move forward in one’s career. Online graduate degrees may be earned in the following disciplines: Aerospace Chemical Civil Computer Science and Software Electrical and Computer Industrial and Systems Materials Mechanical “Our graduate online program ranks among the top in the nation because of our quality of programs and dynamic faculty,” said Christopher B. Roberts, dean of engineering. “We are proud to offer an on-campus equivalent graduate engineering degree to those who want to further their professional goals, but want to do so at their convenience. With our list of degree options continuing to grow, we have the ability to attract more students from all across the country.”
To continue to meet the demand for relevant and in-demand academic offerings for students and industry, Auburn Engineering Online and Continuing Education offers three brand new degrees — the Master of Cybersecurity Engineering, Master of Engineering and Master of Engineering Management. The Master of Cybersecurity Engineering, housed in the Department of Computer Science and Software Engineering, equips students with the advanced education required to analyze, develop, investigate, protect and defend computer information systems. The degree also concentrates on engineering and the technical aspects of cybersecurity. With cybersecurity becoming one of the nation’s most discussed issues, this degree will prepare individuals to identify, assess and provide solutions to thwart cyber attacks. The Master of Engineering degree allows students to design a specific degree tailored to fit their needs and is not limited to one engineering discipline. “The Master of Engineering degree is unique in that it attracts students from all engineering disciplines,” said Roberts. “Our mission is to provide access to the highest quality engineering education, and that’s exactly what we’re accomplishing through this online degree. Students
will have the advantage of earning an Auburn Engineering graduate degree at their convenience and use the degree to fulfill their professional goals.” The Master of Engineering Management, housed in the Department of Industrial and Systems Engineering, is designated for students who are currently working in an engineering-related field and want to expand their career potential. Students who complete 30 hours will earn a Master of Engineering Management in one of four options — manufacturing, occupational safety and ergonomics, systems or product innovation (anticipated in 2020). The degree is the only of its kind in Alabama and was ranked fifth in BestCollegeReviews.org 2018 Top 50 Online Master’s Degrees in Engineering Management. For those students interested in continuing their education, but may not be ready to pursue a graduate degree, graduate certificates permit students to take individual courses in their chosen area of interest. This option allows individuals to continue building their knowledge in a specific area while also receiving academic credit. If an individual applies to Auburn Engineering’s online program, and is accepted, any earned certificates may be later applied toward that student’s degree. The GRE is not required to enroll and there is no limit to the number of certificates a student may earn.
future, all from the comfort of home, work or anywhere. And for students who are eager to expand their knowledge on topics related to their career, graduate certificates offer a perfect blend of becoming better educated in a specific area while banking those credit hours toward a degree.
Mirroring the upward trajectory of the graduate online degrees, several new graduate certificates have been added or will be offered soon. “The graduate certificates offer an excellent opportunity for engineering professionals who want to take a few courses to further their knowledge in their area of expertise,” Roberts said. “Our graduate certificates allow students the flexibility to take courses, grow in their career and work toward a master’s degree in the future if they choose to do so.”
It may be a fast-paced world filled with work and family commitments, but that doesn’t stop individuals from continuing their education whether near or far. Auburn Engineering Online and Continuing Education will continue to change, adjust and grow to reflect the increased demand for online learning — and like its students, can’t wait to see what the future holds.
Auburn Engineering Online and Continuing Education offers a type of versatile program that appeals to potential students in any engineering-related discipline. Students have the opportunity to gain new knowledge, increase their professional opportunities and create a brighter

they have been taught in a real environment.” Harris and his colleagues are building partnerships with industry collaborators that will lead to technological advancements all along the automotive supply chain. “The alliance is working on real industry problems by using academic research to address those challenges while applying advanced manufacturing processes and technologies to solve manufacturing problems. An important goal of the center is to develop robust relationships between industry and academia,” Harris said.
Harris and SAAV are supported by faculty members Sa’d Hamasha, assistant professor of industrial and systems engineering; Tom Devall, director of auto manufacturing initiatives; Daniel Silva, assistant professor of industrial and systems engineering; and Justin Patton, director of the Radio Frequency Identification Lab in the Harbert College of Business. A group of 11 graduate students representing a number of Alabama-based industries are also heavily involved with the center.
SAAV members have completed two projects and there are five active members with projects. Current active members include automotive original equipment manufacturer Honda Manufacturing of Alabama, automotive suppliers Brose Tuscaloosa Inc., Borbet Alabama Inc. and Arkal Automotive, and an electronics-manufacturing consortium that includes Universal Instruments.
“Our faculty bring a wide variety of expertise and experience in solving complex problems,” Harris said. “We are able to implement problem-solving techniques appropriate for the complex problems under consideration. Our engaged and motivated students bring energy, excitement and intelligence, and they’re focused on implementing the problem-solving capabilities
Government participants in additive manufacturing include NASA and the Army Aviation and Missile Research Development and Engineering Center. The completed projects focused on continuous improvement and development of a quality system (a more than 25 percent reduction in first-pass defects) and the implementation of a continuous improvement strategy and
application resulting in the Brose Tuscaloosa plant being recognized as a Best Plant by the corporation. The company is implementing the Auburn-proposed system worldwide at more than 60 plants. Ongoing projects include supply chain simulations and production flow improvement at Honda, quality and productivity improvement at Arkal, Borbet and Brose, and reliability of various lead-free solder materials in mechanical life testing at Universal Instruments.
In addition to solving serious and complex problems for these organizations, Auburn Engineering students are gaining extremely valuable skills. At this time, 100 percent of the students placed in these projects have been offered positions with the companies they were engaged with. To expand on this success, SAAV members also met in 2018 for the first Industrial Advisory Board meeting, with future plans to expand and collaborate with peer institutions and other corporations.

Exploding batteries create chaos. That’s the headline Auburn University Assistant Professor Majid Beidaghi read in 2016 when Samsung’s newest cellphone, the Galaxy Note 7, began combusting inside the pockets and purses of people worldwide. Surveillance footage showed people in restaurants jolting away from their phones as they emitted thick puffs of toxic smoke. Images showed charred bronze cellphone frames next to a man whose leg had just been scorched by the Samsung device, leaving him with second-degree burns. A year later, hoverboards joined the lineup of gadgets susceptible to engulfing in flames, but these hazards are no surprise to Beidaghi. All wireless products have a common

denominator in terms of power source, thus all wireless products are capable of an explosion, he said. In every camera, computer, tablet and cellphone lies this power source, and so too lies the cause for the vast number of explosions reported. The culprit is lithium ion batteries. Beidaghi and his team of Auburn researchers are spearheading the development of a new type of battery that will revolutionize all wireless products, and more importantly, end the flurry of headlines following another lithium ion battery explosion. “We’re working beyond the lithium ion battery. It’s the best battery right now, but we’re developing a safer, more sustainable, multivalent battery,” Beidaghi said. The idea behind Beidaghi group’s multivalent battery is being driven
by earth’s most abundant metal — aluminum. Armin VahidMohammadi, a graduate research assistant in Beidaghi’s lab, is among the researchers making aluminum batteries a reality. The setbacks accompanying lithium ion batteries are juxtaposed by aluminum’s benefits, he said; reactivity being an example. “You can handle aluminum in the air, but you can’t do that with lithium because then...,” VahidMohammadi said before motioning his hands outwards, signaling an explosion. The way a lithium battery discharges is that lithium ions are removed from the anode, or negative electrode, and lose electrons into an external circuit, which is where the functional work is done. Ions then move through an ionically conductive material, the electrolyte, and
become embedded in the cathode or positive electrode. The failures of this system, which can result in explosions, come from charging too fast, physical damage or overheating. Once a spark ignites, extinguishing the flames becomes difficult. Oxygen infiltrating the lithium fuels the fire because the oxidant is self contained in the battery. This, VahidMohammadi said, is why it’s important to make a battery without lithium and with aluminum — the latter is impervious to the effects of air, thus eliminating any chance of combustion. The positives of aluminum also extend beyond safety. Batteries with a metal in the negative electrode are ideal because they give the most capacity and highest energy density. Lithium’s dangerous sensitivity and its tendency to grow dendrites that can cause a short circuit in the battery means using it as an anode is impossible, but aluminum is safe to use as an anode in an aluminum battery. “Aluminum has the highest volumetric capacity among all metals, and we can use this property to make batteries that store a high amount of charge in a limited volume,” Beidaghi said. The rewards brought on by aluminum’s charge density also present a problem. Because of its high charge density from three positive charges, aluminum interacts strongly with other similarly charged ions, preventing the intercalation of aluminum ions into the structure of most cathode materials. If an aluminum battery system can be developed, then theoretically for each ion there will be three electrons, said Beidaghi; meaning an aluminum battery will be much more efficient and powerful than
the lithium battery, which only gets one electron for each ion. “If you increase the energy and power densities of batteries, you could be able to charge batteries quicker, and the charged battery could last much longer,” Beidaghi said. The main obstacle in realizing an aluminum battery was finding a cathode material suitable for an aluminum battery — and the Auburn researchers found just that. “We were working with a new family of materials called MXenes… We took one of the members of this family, used it as the cathode, and made a fully working battery,” VahidMohammadi said. The Auburn researchers are the first to publish research highlighting the potential of MXenes as a cathode material for aluminum batteries. “We have demonstrated that this can work, so it feels good,” VahidMohammadi said. “But it doesn’t come without challenges.” With pioneering research comes unknown problems, and Beidaghi sees a parallel between the initial stages of their aluminum battery research and the research of lithium ion batteries in the 1970s, which was met with skepticism. The notion of lithium batteries was seen as farfetched and an unlikely development. “Not many people believed lithium batteries would work, and it ended up changing the world,” Beidaghi said. “So there is no scientific reason to think aluminum batteries won’t work either.” The surging electric vehicle market could be a prime platform for this research. Just like cellphones, these vehicles are powered by lithium ion batteries and are also prone to the same types of explosions; meaning

people not only risk losing their phone in a pile of ash, but their $100,000 electric vehicle as well. The exorbitant cost of these vehicles is largely because of lithium ion batteries, but having a cheaper battery could change that. Since aluminum is so abundant and easy to extract, aluminum batteries could potentially drive down the cost of luxurious Teslas. “One important aspect of our work is the potential for making electric cars more affordable by making a safer and cheaper battery,” Beidaghi said. Andrew Tormanen, an undergraduate researcher in Beidaghi’s lab, is responsible for changing the structures of materials on nano and micro scales in the research. He also regards developing next-generation batteries as a necessary progression needed in the electric vehicle market. “In Europe, they’re phasing out gas
vehicles for electric, so in the next five years, there’s going to be a rise in the demand for electric vehicles,” Tormanen said. Just as electric vehicles are being heralded for their potential for increased sustainability, aluminum batteries could also be an equally advantageous product for the environment. Recycling lithium from batteries is expensive and difficult, said Beidaghi, but recycling aluminum is something we have done for many years, and can continue to do. The plentiful amounts of the metal and its easy recyclability could be a huge benefactor for sustainability. “If we continue on our current track in our research, we won’t be talking about batteries catching fire in the future,” Beidaghi said while pointing at his phone. “Difficulty is what we want. We are scientists, and we want to solve problems because we’re not afraid of them.”

as well. Using vehicle-to-vehicle wireless communications technology and sensors, two or more trucks can link together and maintain a set, close distance between each other automatically. When the lead truck accelerates or decelerates, so do the following trucks. As the Blue Water Bridge demonstration and subsequent testing on I-69 have shown, this technology offers the promise of increased fuel efficiencies, decreased traffic congestion and improved safety for truck fleets.
Rumbling down Interstate 69 on a crisp fall day in Michigan, a mixed convoy of military and commercial trucks using autonomous vehicle technology snaked its way through Port Huron across the picturesque Blue Water Bridge into Canada and back.
Truck platooning systems could have large benefits in the trucking industry for both commercial and military applications.
Led by a team of U.S. Army and Auburn University researchers, the convoy demonstrated the capabilities of truck platooning technology for a crowd of dignitaries and the automotive press corps gathered at the U.S.-Canada border. The history-making trek in October 2017 was the first international border crossing conducted by the U.S. Army Tank Automotive Research, Development and Engineering Center, or TARDEC, using the rapidly advancing technology. Truck platooning is increasingly seen as the future of freight transport with myriad other applications

“Truck platooning systems could have large benefits in the trucking industry for both commercial and military applications,” said David Bevly, the Bill and Lana McNair Distinguished Professor of Mechanical Engineering and director of Auburn’s GPS and Vehicle Dynamics Laboratory. Since joining the Auburn Engineering faculty in 2001, Bevly and his team of GAVLAB researchers have been at the forefront of research on vehicle dynamics, navigation and control. The lab’s expertise in this area has made it a natural partner for organizations engaged in autonomous vehicle research and development, such as TARDEC and the Federal Highway Administration. Bevly and his GAVLAB team have been at the heart of a $1.42 million FHWA project to evaluate the commercial feasibility and benefits of driver assisted truck platooning, or DATP. It is a form of cooperative
adaptive cruise control for twotruck platoons. Other project partners include Peloton Technology, Peterbilt Trucks, Meritor WABCO and the American Transportation Research Institute. The project has consisted of development and testing of DATP, as well as stakeholder engagement and business case analyses in the trucking industry. The team’s findings have supported their theory that truck platooning technology is near market ready and will provide significant value to the industry and fleet owners. “Humans don’t have the reaction time to allow short distance platooning,” Bevly said. “When you can have sensors and computers controlling that to allow trucks to follow close and draft, you get fuel savings and those fuel savings are a benefit to the economy and to the environment.” As part of the project, the GAVLAB team conducted initial fuel testing at the Transportation Research Institute’s test track in Ohio using Peloton’s prototype truck platooning systems. The GAVLAB team has gone on to develop its own algorithms used in recent testing at Auburn University’s National Center for Asphalt Technology test track, as well as the demonstrations on the Blue Water Bridge and I-69
in Michigan and I-85 in Alabama. GAVLAB-developed algorithms and software operated all four trucks in the mixed military and commercial convoy on I-69. Data from these tests showed that peak fuel savings for the platoon was 6.96 percent at a 30-foot distance, and peak fuel savings for the following truck was 10.24 percent at a 50-foot distance. Even at a 75-foot following distance, the tests showed that truck platoons can yield a 10.11 percent fuel savings for the following truck and a 5.59 percent average fuel savings for the platoon. Considering that long-haul trucking accounts for more than 10 percent of U.S. oil, and fuel takes up 41 percent of operating expenses for truck fleets, the economic impact is substantial. “The heavy truck industry is really a large consumer of fuel so I think there’s a huge potential benefit for fuel savings,” said Grant Apperson, a GAVLAB research and mechanical engineering graduate student. “It can have a huge impact on our economy because this industry uses so much fuel.” The DATP system functions using a low level of autonomy, controlling only the truck’s brakes and throttle. The driver is still in control of
steering and can override the system braking and throttling, if needed. The system operates by pulling together radar for longitudinal sensing, vehicle-to-vehicle communications for exchanging information between vehicles, satellite positioning for verifying distance between trucks, actuation for longitudinal control of the vehicle and human-machine interfaces for controlling DATP settings. Besides the economic upside, the DATP technology can also vastly improve safety by reducing the opportunity for human error. Highlighting how truck platooning technology can improve safety is a key goal for industry and the military, which was one aspect of Auburn’s October 2017 demo with TARDEC in Michigan. That day, the four-truck convoy consisted of two Peterbilt 579 commercial trucks, as well as the Army’s M915
“line haul” tractors carrying flatbed trailers loaded with cargo containers. “It was really interesting to show interoperability between military trucks and commercial trucks using common communication platforms between the trucks,” Bevly said of the truck platooning demo. For the Army, interest in truck platooning technology goes far beyond fuel economy. With military convoys a prime target for attack in conflict zones, the Army has a vested interest in using as few personnel as possible during transport. “It’s about saving lives, first and foremost,” TARDEC Director Paul Rogers told Great Lakes Today, a regional journalism consortium. “It’s about being more efficient and being able to do more with the number of soldiers and the number of trucks that we have. And it’s always about giving the soldier what they need to succeed and come home.”

“The signal hits on the chest of the patient — there is a chest movement induced by breathing — and the acoustic signal changes,” Mao said. “Those chest movements change the feature characteristics of the signal. The smartphone microphone picks up the reflected signal, and the signal processing software is executed to detect the small variations induced by the movements. We are then able to make accurate estimates of respiration rates, with a median error around 0.3 beats-per-minute.”
“We use an acoustic signal to detect respiration rates of a patient,” said Mao, Samuel Ginn Professor and director of the Wireless Engineering Research and Education Center. “Rather than using sensors that attach to the chest or clip to your fingertips, the technology is contact-free, low-cost, easy to deploy and suitable for long-term monitoring of a patient’s conditions.”
The smartphone app-based system has been tested in a living room, an office and even a crowded movie theater. “It has been found to be quite robust when it comes to interfering
noises and different environments, largely due to the short propagation range of acoustic signals,” Mao said. The PhaseBeat system employs the ubiquitous Wi-Fi infrastructure for contact-free health sensing, transmitting Wi-Fi signals from devices such as wireless routers, smartphones or laptop computers. “Again, the signal hits the patient’s chest, and the reflected signal, along with signals from the line-ofsight path and reflected from other obstacles, are received by another device equipped with an IEEE 802.11n card with three antennas,” Mao said. “The received signal is calibrated and analyzed, with the small vital sign signals detected. It works the same way to detect heartbeat signals to measure heart rates, working over a longer distance and even through a wall.” Mao said the technology will eventually be available for use in the home to assist those who are living alone, without the necessity of specialized or expensive equipment. “We can use what is monitored to detect an issue or to compare with certain features that can indicate certain types of disease,” he said.
“By comparing the data, we can detect anomalies and send alarms to the doctor or directly to the patient. “In addition, the wireless system’s signal is able to penetrate obstacles and could be used to locate survivors in the aftermath of a disaster or to detect breathing patterns and sound an alarm to wake a tired driver.” Mao said the next step to making that a reality is to pursue collaborations for testing the technology with researchers in industry or medical schools. “Both SonarBeat and PhaseBeat can capture vital sign signals over an extended period of time,” he said. “Once equipped with the medical knowledge through such collaborations, the team aims to develop algorithms to detect signature features or symptoms in captured vital sign signals for diseases, such as sudden infant death syndrome or apnea. The system also can be used for activity recognition, to detect various activities of a patient, such as a fall, and trigger a warning message to doctors or family members.”
to use the captured respiration signal to control the MRI scanner. If successful, patients would not be required to hold their breath during an MRI scan, making the procedure more comfortable for the elderly and patients with certain diseases. Mao and his team were honored last fall at an international conference for their work on the SonarBeat technology. Their presentation of “SonarBeat:
Sonar Phase for Breathing Beat Monitoring with Smartphones” earned the Best Demo Award at the Institute of Electrical and Electronics Engineers International Conference on Sensing, Communication and Networking. The conference focuses on novel communication technologies and emerging applications and services involving mobile sensing and communication, and ubiquitous and pervasive computing.
