Incoming President’s Message

Greg Gdowski, PhD University of Rochester Incoming RES President June 1, 2020 - May 31, 2022 Dear Colleagues, I am honored to be taking on the role of President of the RES. The RES has a long history of remarkable Past Presidents dating back to 1897. I am humbled to be among some of the most accomplished engineers within Rochester area over this time period. I am also grateful to those that have preceded me, especially Joe Dombowski (2018-20), Mike Triassi (2017-18), and Jon Kriegel (2016-17). They have been instrumental in setting the stage for the continued success of the RES. I am very fortunate to have an extremely talented set of officers in navigating the RES forward including Michelle Sommerman (1st Vice President), Dennis Roote (2nd Vice President), Andrew Hirsch (Treasurer), and Lynne Irwin (Administrative Director). The Board of Directors also provides extraordinary depth in expertise that guides RES activities and endeavors. These individuals include Joe Dombrowski (Immediate Past President), Kenton Hines, Richard Rice, Neal Illenberg, Stephen Day, Brett C. Eliasz, Mike Kurdziel, and the newly added members Dan Weaver and Nancy Crawford. It is with great sadness that Michael V. Triassi, and Lee Loomis will be departing from their roles on the Board. Their guidance and help will have a lasting impact on the RES and will look forward to engaging them on future special projects.

As I look forward, the RES is rapidly approaching its 125th Anniversary. It is hard for me to imagine what Rochester must have been like in 1897 when seventeen engineers came together to begin the RES. Kodak was in its infancy, electricity had been just introduced, and the first Ford model-T had yet to be invented. It is remarkable to me that the first RES President, Edwin Fisher, likely personally knew Frederick Douglass and Susan B. Anthony. While we have made strides since that time in eliminating racism and establishing equal rights, clearly the recent incidents resulting in the death of res news - incoming president’s message

George Floyd illustrate that we as a society in Rochester must aggressively continue the work of our most celebrated historical figures. Like you, I am angered and saddened by the recent incidents in our country. Violence is not the solution. Frederick Douglass once said: “I prayed for twenty years but received no answer until I prayed with my legs.” It is time for us to take a more pro-active role within the community to move us closer to the United States originally envisioned by Douglass and Anthony.

How can you help make a difference?

We have tried to make this easy for engineers at the RES by facilitating engagements in important community STEM-related activities such as: E3, Stem-Bridges, and the Terra Science Fairs. One activity where we need your help is in providing tutoring for the Walter Cooper Academy, School #10. With the help of Lee Loomis, the RES established the Tutoring Team Project in 2012 at School #10. A school named in honor of Dr. Walter Cooper (1996 RES Engineer of the Year). In 2019, the RES Tutoring Team included more than 20 tutors, providing over 100 hours of support to the scholars and their teachers, each month. They were making a difference in the lives of many students. Your help is needed more now than ever! School #10 experienced layoffs and was closed for the Covid-19 crisis. The new school is slated to be completed shortly and we are hoping to continue our efforts in tutoring in the upcoming year. Please contact me or Lynne Irwin if you are interested in helping with this effort. If you do not have the time to help with tutoring, please consider giving a charitable donation to this effort. Your sponsorship will greatly help us to continue to support tutoring and other stem-related activities such as Science Fairs.

All my best, Greg Gdowski

Outgoing President’s Message

Joseph Dombrowski, PE Retired M/E Engineering Outgoing RES President 2018 - 2020 It is the beginning of May as I write this it looks like spring has arrived. Sheltering in place because of Corona virus is not much different than retirement!

There have been many cancellations; PLEASE VERIFY IF EVENTS ARE ON OR OFF WITH THE OFFICIAL SOURCE BEFORE ATTENDING! Please have no doubt that the RES will continue on in this time of crisis. We are exploring our options to keep open, but I believe we have things well in hand.

Our monthly board meetings are now virtual (thank you Greg!) as will be the annual meeting on 5/27/20.

The Gala scheduled for 4/18/20 was cancelled for this year due to Corona virus fears. The Engineer of the Year, Young Engineer of the Year, Finalists for Young Engineer of the Year, Engineers of Distinction, and our high school and college scholarships selections will be honored virtually at our annual meeting on May 27, 2020. More details will follow. Many of our Gala sponsors generously let us keep their sponsorship dollars to meet our ongoing expenses. They will be also be honored at the annual meeting.

The Engineering Symposium (PDH Fest) was rescheduled to September 22, 2020 from April 28, 2020 also due to Corona virus fears. The re-planning effort is already underway (thank you Chris DeVries).

We will have sponsors but no venders this year at the Riverside Convention Center. And always, parking will be free, and 7 PDHs and a free lunch are available at a very modest fee. Help is always appreciated but we will especially need registration volunteers on 4 | The ROCHESTER ENGINEER JUNE 2020

September 22nd. Registration is planned to re-open August 1, 2020. Details regarding the rescheduled event will follow.

As part of the year-end process, we were looking for nominations for our Board of Directors! Thank you to those who have joined the RES and volunteered to be directors.

Our tutoring and Science Fair effort at Dr. Walter Cooper Academy were thrown into a tizzy with the Corona virus and recent layoffs instituted by the Rochester City School District; an effort to get it back on track in the fall is ongoing unless the virus interferes.

If you have any concerns or input, or feel the need to volunteer for anything or to help us out, feel free to contact the RES via the website at www.roceng.org or me directly at jdombrowski3@rochester.rr.com.

As always, I hope to see you at one of our RES events, the 2021 Gala, or the Symposium on 9/22/20.

As this is my outgoing message, I would like to thank the board, both past and incoming and especially Lynne, for making my job much easier than it could have been. Times have been unusual to say the least, but with all of your help, RES will come through it successfully and better than it ever has been!

JUNE 2020 The ROCHESTER ENGINEER | 5

Rochester History Continuing with the historical sampling of the earlier writings on behalf of the Rochester Engineering Society, the years following "The Great War", into and through the “Great Depression”, continued to be a time of reaching out for the maturing Society, both locally and nationally. The meeting minutes describe a series of technical discussions and presentations intended to broaden the technical horizons of the membership (especially the CE's, ME's and EE's). The RES affiliated itself with a number of National technical societies, adopted local Affiliated Societies, frequently held joint meetings with them and continued taking action on a growing list of public matters. Certain issues of standardization, some crucial to public safety, became the responsibility of the RES and its affiliates. In the pervasive economic downturn of the “Great Depression”, the magazine offered classified advertising for unemployed engineers, technicians and draftsmen and took other steps to try to deal with the crisis. Still, it continued its effort to shape the function, purpose and infrastructure of the City of Rochester, and beyond. World War again affected the Society, taking away many of its leaders while providing opportunities for others to step forward to fill these vacancies. In an effort to provide even greater perspective on the happenings and concerns of the day, a synopsis, featuring selected items from "The Rochester Engineer" has become an integral part of this series. The Second World War and the Korean Conflict are now history, and the Vietnam War has recently become a focal point. These experiences have changed the face and, no doubt, the future of the community. The Rochester municipal leadership and the industrial community have become immersed in the cold-war, growth economy.

February 2, 1972 (Board Meeting, Bausch & Lomb) (continued) RES Employment Committee Chair, Graham

Chamberlain announced that a Rochester Area unit of Volunteer Engineers, Scientists and Technicians (R.A.V.E.S.T.) had been formed, and was being led by William Tippy, an RES Member and local consultant. A first meeting of this group, at Monroe Community College, was attended by approximately 150 unemployed engineers, seeking support in their current job searches. This group is being supported by the American Institute of Aeronautics and Astronautics (AIAA), under a contract from the US Dept. of Labor. Reporting for the RES Membership Committee, George Landberg announced goals for the coming year of 200 new members, fifteen Participating Companies and five new Affiliates. He also proposed holding a dinner for a selected group of Plant Representatives who will be responsible for recruiting new members in their respective places of work, and he presented the need for a new RES brochure, detailing the benefits of RES membership. The Board approved a budget of $550 for this project. Reporting for the 75th Anniversary Committee, John Schickler announced that they were hoping to solicit a total of $15k - $20k in support funding for this celebration, and they had recently received $7,500 from Eastman Kodak for this purpose. The Board approved seven new Regular Members, two Junior Members and one Student Member. On behalf of the “Operation RESOURCE” Task Force, Ed Anthony reported that they are drafting the final report with recommendations, including; establishment of combined City-County Solid Waste Management Team, acquisition, installation and operation of a shredder, hiring of a competent company to establish a dynamic plan for maximum recovery of resources from solid waste, and that the City & County proceed with recycling operations, a composing system or, if these are determined to be not feasible, an incinerator system. The Career Guidance Committee reported that the RES Explorer Post now has a forty-person enrollment, making it the largest in the region.

“The Rochester Engineer” (February 1972)

The RES Luncheon Series for the next four weeks was announced; “A 6 | The ROCHESTER ENGINEER JUNE 2020

A Sampling from the Archives of the Rochester Engineering Society...1897 - 1972

Progress Report on Highway Safety” by W. Russell Laidlaw, Rochester Products Division of General Motors, “A Modular Traffic Signal Controller” by Jerome O’Neill, General Railway Signal Company, and,“How to Plan for a Human Community”

by Stewart D. Moot, President, New Wayne Communities, Inc. For the first time in its fifty-year history, this issue provided a complete recounting of the proceedings of the most recent (as of printing time) RES Board meeting.

March 1, 1972 (Board Meeting, Bausch & Lomb)

The Board approved the applications of fourteen new Regular Members and four Junior Members. The R.T. French Company was accepted by the Board, as an RES Participating Company. On behalf of the Membership Committee, George Landberg reported that fifteen Plant Representatives had attended a successful Membership Promotion dinner meeting at the University Club. A brochure was ready to be sent to the printer. The Board also approved motions to suspend, at six-month intervals, RES dues payment requirements for unemployed members and to offer a non-transferrable RES Luncheon ticket to each member, upon payment of their annual dues. RES Director, John Schickler reported that he had secured Robert W. Decker, Vice President of General Motors, to be the speaker at the RES 75th Anniversary Engineers’ Joint Dinner, on April 26th, 1972.

“The Rochester Engineer” (March 1972)

In April of 1972, the RES planned to present a multi-themed exhibit, “Technology Trip”, featuring sponsored displays with themes including: Transportation (W. Russell Laidlaw of Rochester Products/GM), Communication (John L. Wheeler of Xerox Corp.), Home (M. John Corson of RG&E), Health (Charles Hancock of Castle/Sybron) & Future (Walter Hausler of General Railway Signal). These displays were to be presented for three days, at Midtown Plaza. Two recent additions to the RES Luncheon meeting schedule included; “The World Trade Center” by Seymour Cohen, Tishman Realty & Construction Company and “Operation RESOURCE” by the RES Task Force on Solid Waste Management. An RES-sponsored evening seminar, “Motivation and Human Values” by Franklin C. Basler, Jr., Director of Rochester Downtown Ecumenical Ministry was announced. An article on the VEST Program announced that, as the result of the RES’ support, the Rochester Area Volunteer Engineers, Scientists and Technicians (RAVEST) was up and running, operating as a clearing house for job opportunities, especially focused on providing assistance to former employees of the US Aerospace Program.

Subsequent articles in this series will describe the RES' continuing outreach to other technical societies as it considered its role in this and the larger community, along with more of the activities of the RES as it moved to be of greater service to its membership, especially those suffering from current economic crises, and adopted a greater role in shaping the future of the City and its environs. Noted also, will be the contributions made by RES members in the struggle to meet the challenges coming out of World War II and the Korean Conflict, as well as a hoped-for period of postwar growth and prosperity. These articles will also feature an impressive array of RES activities in support of post-war re-emergence of Rochester area industry, and the ensuing prosperity of the second-half of the 20th Century.

We welcome your questions and comments on this series.

Technical Corner So, what is the “Norm” when sizing neutral conductors on a service or a branch circuit? Doesn’t everyone just match the phase conductors? Perhaps in some cases using a 200% rated neutral is required due to high anticipated harmonics or neutral current?

In this article we will discuss a scenario where you can actually provide a neutral conductor that is smaller than the ungrounded phase conductors. This special circumstance is outlined in Article 705 – Interconnected Electric Power Production Sources and is meant to apply to circumstances where the neutral is not being used to carry current.

Refer to 2017 NEC Section 705.95(B): a conductor used solely for instrumentation, voltage detection, or phase detection and connected to a single phase or 3 phase interactive inverter, shall be permitted to be sized at less than the ampacity of the other current-carrying conductors and shall be sized equal to or larger than the equipment grounding conductor.

Example: Lets say you are sizing AC conductors for a 50kW, 3 phase, 480/277V interactive inverter. Assuming Voltage Drop is insignificant what size conductors would you need?

50,000W/(480*1.73)=60.21Amps Taking this amperage and multiplying by 125% per NEC 705.60(B) you get 75.26Amps and using the next size up you would need to use an 80A circuit Breaker.

Using the wire sizing charts and the 60 degree column you get #3 AWG for the phase conductors and normally you would use a #3AWG for the neutral to match the phase conductors. However, in this case the section 705.95(B) above is satisfied, therefore, the neutral size may be sized per table 250.122 which is also used for the equipment grounding conductor based on the rating of an overcurrent protection device in the circuit ahead of the equipment.

So here we could use a #8 Neutral and a #8 Ground.

Hopefully this article finds you well and can be used as a reference for your project needs. If anyone would like to contribute to the RES magazine and add an article or would like to request information on a specific topic (not limited to Electrical) just email me at beliasz@bergmannpc.com. As always, any comments are appreciated…! Thank you for reading.

RES News How do you arm a STEM Teacher with real-world application examples?

Put an Engineer in the classroom!

In the 1990’s, Eastman Kodak Company jumped the gun, starting a family of STEM initiatives, years before the Government coined the STEM acronym. The name of these programs was the 21st Century Learning Challenge (TCLC), and at our peek, we were 1500 engineers and technicians, visiting Rochester City School Classrooms, twice a week for two-hour visits, during the entire School Year. This effort continued for nearly ten years, and not only pre-dates our recent STEM excitement level, but delivered support on a scale we have yet to match.

Many of the volunteers in these programs were, and still are, members of the Rochester Engineering Society (RES). In the intervening twenty-five years, many have retired, or are about to retire. That makes them even more available as STEM Coaches, than they were as Kodak employees.

The RES is working to put technical people in K-12 Classrooms, throughout the Greater Rochester area, as STEM Coaches. Their presence will:

•

•

•

Help the Teacher stay current with our ever-changing technology.

Provide real-World Application Examples, making whatever is being taught, real enough to be worth remembering.

Support the teachers with not only the delivery of STEM concepts, but perhaps more importantly, the design and delivery of STEM related hardware.

Last year we had six STEM Coach, doing Classroom Visitation at School #3. That was so successful that RCSD is interested in expanding this program to involve nine STEM Coaches this year.

The RES is specifically seeking Retired, Technical people, (Engineers, Technicians, Machinists, Entrepreneurs or anyone whose work would allow them to visit during School hours), as STEM Coaches.

We currently have more than 30 Coaches, and are connecting them with 13 Rochester-area Schools.

“This is a life-changing experience!”

RES News - Tutoring Team Good News at Dr. Walter Cooper Academy…

There is much progress to report on the renovation of #10 School, at 353 Congress Ave. A recent “Zoom” meeting provided a virtual tour of the facilities, where approximately two-thirds of the original structure has been replaced with a new main entrance, gymnasium/auditorium with a stage, and expanded building space, including more than 20 additional classrooms. The remaining one-third of the original structure, with its “Legacy Design Features” has undergone extensive renovation to preserve the hardwood floors, cabinets and decorative wood carvings of the tribes of the Iroquois Nation. Despite pandemic-related delays, the project is still on schedule for a June 26th construction completion, followed by a Summer 2020 move-in.

We have every expectation that the RES Tutoring Team will be asked to resume its work, next Fall, at the newly-renovated campus, in City’s Nineteenth Ward. When that happens, we will once again need the dedicated service of our current RES Tutors and, no doubt, additional tutors working with the teachers and students, in support of the NY State Science Curriculum.

Does this sound interesting to you, or maybe to some of your friends? Could you see yourself supporting the presentation of science curriculum to students, ages five to eleven? Who was it that showed you how science could “make a difference” in your life? Could you help introduce someone to science, yourself? Do you think you can make room in your life for this important challenge?

We will continue to build our RES Tutoring Team, now for the 2020-21 school year… We have been giving “Lunch & Learn” presentations in several Rochester area firms and professional groups, to inform and inspire prospective new tutors. We have “hit the ground, running”, and we need your support...Can we schedule a presentation with your firm, your work group, your church or family, sometime this Spring?

Even just two hours a week of your time can make a big difference in the life of a Dr. Walter Cooper Academy Scholar…

Questions??? Reach out to RES Past President Lee Loomis and the RES Tutoring Team at…Rochester Engineering Society (585) 254-2350, via website: www.roceng.org, or via email: leeloomis46@gmail.com, (585) 738-3079 (mobile & text)

RES TUTORING TEAM, FREQUENTLY ASKED QUESTIONS...

RES News - Tutoring Team Dr. Walter Cooper Academy “2020 Science Fair” Postponed due to New York’s COVID-19 Response In the face of the COVID-19 crisis, and motivated by a concern for the collective health and well-being of our communities, the Governor has closed all New York State public schools, for the balance of the school year.

I have consulted with the Administration at Dr. Walter Cooper Academy, and we have decided to postpone “2020 First Annual Dr. Walter Cooper Academy Science Fair” until further notice. Hopefully, we will be able to resume our support for, and involvement in, this important educational opportunity for our Cooper Scholars, next Fall.

As you may recall the Rochester Engineering Society (RES) was invited to help establish a new tradition, back in the late 2018-19 school year. The School-Based Planning Team, and the Parent-Teacher Organization (PTO), including parents, teachers and administrators, requested the support of the RES in developing a Winter-Spring 2020 science fair at #10 School.

In response, we recruited a small team of Volunteer/Mentors (V/M’s) to work with nine identified Cooper Scholars (Grades 4 – 6), to prepare them for a Science Fair. We are hopeful that these Volunteer/Mentors will again be available when we resume the development of our Science Fair in the Fall of 2020.

Please consider supporting us, as we continue to seek and develop ways to expose our Cooper Scholars to the many fascinating aspects of Science, Technology, Engineering & Math (STEM) in their futures.

If you think you might be able to make room in your schedule to help with this effort, please reach out to RES Directors, Lee Loomis (leeloomis46@gmail.com) or (585) 738-3079 (mobile & text) or Jon Kriegel (jkriegel@rochester.rr.com) or (585) 281-5216, for more information, and to volunteer for this important, potentially life-changing opportunity. res news - tutoring

RED Rochester Building 87 Chiller Replacement and Plant Upgrades - Robert M. Gleason III, E.I.T. As many Rochesterian’s know, Eastman Business Park (EBP) is no stranger to cutting-edge and innovative technology. With the pursuit of sustainability driving so many conversations within the world of architecture and engineering, EBP is once again at the forefront of those conversations, becoming home to the world’s largest magnetic bearing chiller.

In partnership with RED-Rochester, LLC., C&S Companies was selected to provide engineering and design services for the first installation of its kind. The 3200 ton chiller, equipped with eight 300hp magnetic-bearing compressors was installed to replace an existing 3,500 ton back-pressure steam unit. The existing unit was nearly 50 years old and no longer operational.

Due to the nature of the project, and the amount of existing piping and conduit to be re-used, C&S’s Building Information Modeling (BIM) services team was deployed to provide a three-dimensional scan of the existing facility. Using the Leica RTC360 LIDAR scanner, the team was able to capture the existing conditions of the building within 1/8” accuracy in only a few hours. After completing the scanning phase, a program called Edgewise was used to process the information gathered in the field. Edgewise uses groundbreaking algorithms to automatically identify and extract piping from cloud points and export them as Revit family objects.

3200 Ton Chiller installed at RED Rochester’s Building 87

The scan was also responsible for producing High-Dynamic Range (HDR) imagery that allows you to view and measure distances from a program called Jetstream. The advancement in this type of technology has been extremely useful for architects, engineers and designers.

400HP variable speed, vertical inline chilled water pump & step-down transformer (2.4kV-480V).

Nine harmonic mitigating filters.

Active front-end variable frequency drive (VFD) and step-down transformer (2.4kV-480V) for an existing 700HP chilled water pump.

200HP premium efficiency motor and accompanying VFD. Four new horizontal end-suction condensate return pumps with pump mounted VFD’s.

Continuing with the theme of sustainability; 15 VFD’s were added to the existing electrical distribution system as part of the plant improvements. With the VFD’s, came the conversation of harmonic contribution. RED’s Building 87 is composed of both a 2.4kV and 480V main-tie-main switchgear lineup; and the need for clean power is essential to operations at the plant.

have been combatting harmonics for years, however, this battle has escalated in recent years due to the influx of non-linear loads, namely VFD’s. Harmonics are generated through non-linear loads by drawing current and creating abrupt pulses that distribute themselves back into electrical systems. Facility electrical systems will remain very resilient to these harmonic currents until the harmonic contribution begins to approach 15%. Harmonic contribution can become a leading factor in the following occurrences:

- - - - - - - -

Nuisance tripping of circuit breakers.

Harmonic resonance.

Capacitor bank failures.

Equipment overheating.

Neutral overloading.

Generator issues.

Electro-magnetic interference to sensitive equipment.

Motor winding burnout.

As can be seen in the list above, harmonics are no laughing matter and cause significant issues for all types of facilities that rely heavily on the electrical grid. The results of the aforementioned items can cause additional cost implications including; maintenance and replacement of equipment, downtime/system interruptions and reduced system capacity.

The entity that is responsible for overseeing and providing standards for VFD’s is the Institute of Electrical and Electronics Engineers (IEEE). The specific standard responsible for setting the guidelines around harmonic contribution is IEEE Standard 519, Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems. Table 1 from IEEE 519-2014 is displayed below and can be used as a guideline for the total harmonic distortion (THD) limits in relation to voltage at certain points in the system.

A common misunderstanding for engineers and designers is the idea that these percentages must be maintained at the piece of equipment that is being installed. Many times engineers and designers will simply confirm with the VFD manufacturer that their particular piece of equipment is IEEE 519 compliant without looking at the system as a whole. As you can see from the table above, the bus voltage is referenced at the Point of Common Coupling (PCC).

The PCC is described as, “The point on a public power supply system, electrically nearest to a particular load, at which other loads are, or could be, connected. The PCC is a point located upstream of the considered installation.”

More often than not, the PCC is located at the main switchgear near the utility tie-in. cover article

At Building 87, the PCC was located at the 2.4kV switchgear which resulted in aiming to maintain a THD percentage of less than 5%. In order to understand the harmonic contribution output of the new VFD’s and their impact on the existing system, a harmonic analysis of the existing electrical system was performed. It is important to note that this analysis would not have been able to be performed without the information gathered in the field by RED’s High Voltage Team.

Broadband Deployment Snapshot, May 2020

COVID-19 Puts Spotlight on Decades-Old Issue: An Engineering Perspective — Ben Gustafson, PE, Director, HUNT-EAS Rochester (May 6, 2020, Rochester NY)

Broadband Deployment Snapshot With remote education, working, and emergency service concerns dominating the national and New York State news cycle, the COVID-19 pandemic has dramatically brought to the fore an already long simmering, broadband deployment issue.

The unparalleled broadband demand of early 2020 has transformed what had been previously couched as a “rural equity matter” into a full-blown, “fifth-utility” headline. For those already engaged in the broadband narrative, the recent stories of parents, students, and remote workers going to libraries and WiFi-lit parking lots to accomplish daily tasks are already too familiar.

According to CNN, a 2018 report from the Federal Communications Commission showed that more than 18 million Americans nationwide lack access to any high-speed internet, and a 2018 Microsoft study estimated about half of Americans – 163 million people – do not have high-speed internet at home.

The percentage of New York residents and businesses served by “wired or wireless broadband” has gone from 70 percent in 2015, when Governor Cuomo first announced his “Broadband for All” program, to 98 percent. During that time, loopholes that allowed the Internet Service Providers (ISPs) to claim that an entire census tract had full coverage, even if it was only one household, have been largely exposed and closed. Cuomo also put $500 million toward grants to extend service to rural areas, but some of that work is also still incomplete, and some residents are being served by satellite service they complain is inadequate.

For their part, prior to recent New York State funding increases, the ISPs countered that the cost of disseminating broadband to isolated pockets was economically unfeasible. Those debates were largely ended in 2019 when the Cuomo administration threatened to void Charter-Spectrum’s NYS operating licenses and create roadblocks to its merger with Time-Warner after the massive ISP reportedly claimed credit for service in urban areas.

Ultimately, Charter agreed to build out more broadband service, and the deadline for the company to finish the job was extended to September 2021.

More recently, Spectrum asserted that it was “paying 100% of the cost of the 145,000 homes we are building in underserved areas in New York State, and do not receive any government subsidies. Charter plans to meet the state requirement of 145,000 by Sept. 30, 2021”.

During the last several months, state, county, and local officials have been overwhelmed with reports of slow internet speeds, simple unavailability, and unaffordable services in both urban and rural settings.

Faced with reports of entire school districts being forced to stop remote-teaching new material because several students lacked accessibility, and having an enormous segment of the working population toiling 16 | The ROCHESTER ENGINEER JUNE 2020

feature article

with slow and sporadic “through-put” service, it seems likely that broadband deployment will not retreat to the trenches anytime soon.

Further underscoring that argument, the pandemic has also laid clear that to fully serve their communities public-safety providers need ubiquitous broadband capacity.

An Engineering Perspective While it seems almost quaint to look back at the 2019 Cuomo budget and its promise of $150 billion in infrastructure improvements, broadband-system construction is likely to continue.

From a consulting and engineering firm’s perspective, those efforts begin with strategic financial planning exercises with municipal, business, and academic partners about which service model a community desires and can afford.

For example, at HUNT Engineers & Architects, their designers and grant writers are actively collaborating with K-12 and municipal partners to achieve this goal using Smart School Bond Act Funds and USDA ReConnect Grants, respectively.

At the outset, municipalities need to choose between collaborating with their incumbent ISP, or potentially designing, building, and maintaining their own network, or creating a leasing combination in-between. Once those decisions are made, into the equation will step information technologists, surveyors, site/civil engineers, construction managers and inspectors, and, ultimately, system maintenance teams.

At Yates County, New York, the county’s goals in developing an all-encompassing Internet service system resulted in initial investigations between the County and HUNT Engineers that centered on what assets Yates currently controlled and which delivery model would be most appropriate. Options included a combination of subsidizing existing private ISPs, expanding the County’s existing dark fiber system, outsourcing the system, or developing a County-owned and operated model.

In addition to the traditional engineering, HUNT offered the County the following broadband feature article

business and operational services: applications, contract documentation, bidding, and documentation. HUNT also secured a $10.3 million USDA ReConnect Grant Application on behalf of the County.

Across the border in Pennsylvania, HUNT partnered with the Central Bradford Progress Authority to address the county’s needs for emergency communications, connectivity for county facilities, wireless towers, and most importantly, community broadband services. To accomplish this task, HUNT designed a dark, or unlit, fiber network that will provide connectivity to county buildings, towers, emergency service locations, as well as provide enterprise services to businesses in the area.

This network will provide inexpensive leases to local ISPs to encourage county-wide broadband development. Due to Pennsylvania laws restricting public entities from providing Internet services, HUNT is providing consulting services to find creative solutions that the Progress Authority could use to further broadband development as much as possible. Once completed, the Bradford County Open Access Network will include 270 miles of fiber and extend to within six miles of any county residents.

Additional broadband engineering services include: boundary and topographic surveys: ALTA surveys; site planning; aiding in utility ROW determinations; pole surveying using HUNT’s pole measurement and documentation system; forging pole attachment agreements; designing overhead splice enclosure point and overhead lines, including pull boxes and concrete capping; designing and adding redundant communication, fiber-network cable and increasing local ISP’s capacity; and, determining whether Fiber-To-The-Home (FTTH) networks are in alignment with federal and state funding requirements. q

Managing Remote Projects is Suddenly Essential

By Lori Marra, Senior Consultant at RGI International According to a study published by Regus, an international company that provides flexible workspace, prior to our now pandemic world, 54% of their global respondents confirmed that people were already working remotely 2.5 days a week or more. (regus.ca/workcanada/the-workplace-revoluttion) In our pandemic world, virtually everyone is working remotely, and this will most likely accelerate the acceptance of a more remote workforce in our post-pandemic world economy.

How can we bring some order to this sudden surge of remote collaboration? Even more importantly, how can we successfully manage our projects when they have suddenly all become remote projects?

Projects managers must manage a given set of resources to complete a project. In recent years, remote teams have been a part of these resources but not exclusively. Today, and for an unforeseen future, virtually all of our teams are remote. So, remote collaboration and communication take on increased importance.

Project managers manage people, activities and costs to complete a project. This article focuses on the people side of this equation and also addresses how to create a professional image in a remote environment.

Through seamless remote communication methods, leaders can get people to • •

•

•

work well together, even though they are apart, create collaborative work environments that are open to everyone, encourage people to share mistakes or unforeseen obstacles and, react quickly to issues even when we are apart.

Here are some approaches successful project managers have used: 1. Create common data shares using tools.

2. Agree upon standard protocols for remote 18 | The ROCHESTER ENGINEER JUNE 2020

communication, and ensure that people talk frequently and get to know one another.

3. Create collaborate work environments that are open to everyone.

4. Schedule informal remote gatherings: • Lunch hours or lunch and learns • Trivia gatherings • Coffee chats • Happy hours • “Open door” policy for quick check-ins 5. Hold daily check-in meetings to review any issues.

6. Create a common, central log book for documenting items.

7. Show empathy and understanding when things don’t go as planned.

8. Agree on a common communication channel for emergencies.

9. Delegate authority to react with different people in different time zones.

10. Allow brainstorming to develop accountability and shared solutions Working remotely often means working from home and with that comes a much more relaxed persona. It’s important that you don’t become sloppy and create an unprofessional image. Whether you are a leader or an individual contributor, be aware of • Cutting the background clutter • Using nonverbal queues • Being aware of your audience’s needs • Learning the online tools and using the interactive features • Communicating effectively

Cutting the background clutter

This doesn’t mean you don’t have anything behind you but make sure it is professional. Your audience will be distracted by looking at the “stuff” behind you. Position yourself so your face is in the middle of the screen.

Using nonverbal queues

Nearly 70% of communication happens non-verbally and get to the point

d

our remote tools can help us or hurt us. Pay attention to the cues you are sending and watch for cues others may be sending.

• Look directly at the camera. Eye contact instills trust and confidence. Consider using two screens so you can see other content if necessary.

• Smile! This creates rapport and fosters connection.

• Don’t move around. Use gestures but don’t reach for items outside of the image.

• Speak at a public speaking rate. This is typically slower than you speak when you are in a small group.

• Eliminate the back and forth chit-chat because it ends up cutting others off.

• Warm up your voice before joining the remote environment. This will improve your voice quality.

• Be conscious of tone, inflection, pace, and uhms.

Communicating Effectively

Being aware of your audience’s needs

Be Concise • Extra words distract and clutter the message.

Especially in remote environments, you need to say what you have to say and that’s all.

• Remember you are communicating technical information and not writing a 500-word essay for your English teacher.

Although we are remote and often alone, we need to be conscious that there is an audience out there watching us and trying to interact with us.

• Keep your camera on.

• Wait for people to respond so you don’t “bump” into each other.

• Be a great listener.

• Be a good moderator: this is even more work than in person. Write down names and address people personally, especially if you want to go back to someone’s comment.

• Don’t multitask. Not only is it a waste of your time, but others will pick up on it and it is disrespectful.

Learning the online tools and using the interactive features

Take the time and make the effort to learn the capabilities and limitations of the remote platform and the interactive tools that can facilitate communication.

Here are some examples: • Chat • Mute • Polls • Hand raised • Share screens • Share files • Whiteboards • Different screen views • Practice modes • Recordings get to the point

One major key to any successful project is communication. When it comes to remote projects, communication is even more important. Everything you communicate, in speaking and writing, must adhere to RGI’s three Cs: Clear, Concise, and Complete.

Be Clear • Always use language that is appropriate and straight forward for your audience.

• Use simple words which are easy to read and listen to.

• Avoid vague, weak and ambiguous words that leave too much room for interpretation.

• Use eloquent words that say more: “perfect” rather than “good”.

Be Complete • Effective communication happens when you know who your audience is and understand what their interests and questions will be.

• Answer only those and you will keep their attention and remain focused.

• Stick to “need-to-know” details and avoid the “nice-to know” information.

Campus News Computational Tools for Design of Transmissions for Robotic and Aerospace Applications Finite element models for efficient and sustainable design

by Eloy Yague-Spaude, Rochester Institute of Technology Current robotic and aerospace applications require mechanisms to be as lightweight and small as possible. These applications utilize electric motors to provide motion, but they tend to work at high rotational speeds. Strain wave gear (SWG) drives play a fundamental role as the transmission from these electric motors by providing large speed reductions while keeping the entire mechanism compact and lightweight. The Gear Research Laboratory at Rochester Institute of Technology is developing computational tools for design and simulation of SWG drives, among other types of gears, to achieve the best design without using trial and error. The developed tools include two- and three-dimensional finite element models based on the design parameters of SWG drives, which serve to simulate their meshing process and observe their operating stresses. These finite element models and the stress information obtained with them allow it to improve the mechanical performance of SWG drives.

Strain wave gear (SWG) drives are a particular type of coaxial gear reducer which transmits power and converts rotational motion with three parts: an elliptical cam or wave generator, an external gear on the open end of a cup-shaped spring called the flexible spline, and an internal gear called the ring gear, as shown in Figure 1 (a). In the most common layout of SWG drives, the input goes through the wave generator which deflects the teeth of the flexible spline into meshing with those of the ring gear. The ring gear is fixed, and the closed end of the cup of the flexible spine constitutes the output, as shown in Figure 1 (b). The second most common layout of SWG drives uses the ring gear as output and the flexible spline can deflect but not rotate. A single SWG drive provides a much larger gear reduction ratio than traditional gear drives, which would require several stages, shafts, and bearings to achieve the same reduction. Besides, the teeth of SWG drives mesh in two regions, where each region has several pairs of teeth in contact, increasing the load they can transmit.

Since the invention of SWG drives in 1959 by Clarence Walton Musser, their design has been challenging due to the flexible behavior of the flexible spline. Although extensive

research has been done to understand the behavior of SWG drives and improve their performance, these research efforts mostly started two to three decades ago because SWG drives were not being utilized until the 1980's and 90's. Due to their large gear reduction ratio capabilities, this type of gear drive constitutes a remarkable invention towards the development of robotic and aerospace applications. Their large velocity reduction is provided in a considerably reduced space and low weight compared to traditional gear drives. The latter drives, however, have been studied for centuries, whereas SWG drives lack a strong body of literature, methodologies of design, and computational tools to obtain improved designs without using trial and error.

Consequently, and due to the short existence and utilization of SWG drives, there are still gaps in the existing literature and the comprehension of their behavior. These gaps motivate the development of computational tools for design of SWG drives that include two- and three-dimensional finite element models.

The lab’s current process for designing gear drives consists of using a virtual gear generator together with a finite element

solver to evaluate their mechanical behavior. The virtual gear generator produces the gear geometries based on their design parameters and manufacturing processes. Then, it generates finite element models to be analyzed in the finite element solver. The solver provides the solution of the finite element models in terms of stresses that serve to evaluate the strength of the gears and their capability to transmit the required load.

with those of the ring gear until contact is established. During these steps, the wave generator engages with the bore of the flexible spline and the output load is applied to complete the setup for simulation of meshing of SWG drives. From this step on, the model represents the behavior of SWG drives in operation by rotating the wave generator inside the flexible spline.

The two-dimensional finite element model of SWG drives includes a slice of the tooth regions of both the flexible spline and the ring gear as deformable parts, as shown in Figure 2.

The wave generator is included as a rigid part, which rotates inside the flexible spline throughout the analysis to simulate the meshing of SWG drives. Considering the typical layout of SWG drives, where the flexible spline is the output and the wave generator the input, the ring gear is locked in position and output torque is applied to the flexible spline to simulate the transmitted load during operation.

The two- and three-dimensional finite element models satisfactorily represent the static behavior of SWG drives during operation. The main difference between the models consists of considering the full geometry of the drive, which significantly enhances the resulting insight about the behavior and mechanical performance of SWG drives. Although simple and computationally efficient, the two-dimensional model is not capable of representing the conical deformation imposed on the flexible spline when the cup-spring is considered. This deformation is fully shown in the three-dimensional model, which emphasizes the need to apply geometry modifications to compensate the effect of the deflection while strengthening the teeth and improving the mechanical performance of SWG drives.

This two-dimensional model serves to evaluate and improve the mechanical performance of SWG drives based on the obtained stresses as a function of the input design parameters of the drive. However, this model cannot reproduce the effect of the cup-shaped spring of the flexible spline and its deformation along the face width of the teeth. This evidences the need to use a three-dimensional model of SWG drives.

The three-dimensional finite element model of SWG drives includes the geometry of the flexible spline with its cup-shaped spring, as well as the ring gear as deformable parts, as shown in Figure 3. The wave generator is still defined as rigid, but it is represented by its outer surface rather than a wire rigid element.

The virtual gear generator provides the geometry of the different elements of SWG drives for the finite element models without any deflection applied. For this reason, both finite element models operate similarly through a set of steps. The initial steps deflect the teeth of the flexible spline into mesh college student article

SWG drives are remarkably suitable for lightweight, compact applications where large conversion of motion is required.

Current robotic and aerospace applications take advantage of this type of gear drive even though their development requires several trials to improve designs. By improving the mechanical performance of SWG drives, the two- and three-dimensional finite element models ease the burden of resources and time that trial and error approaches require. These finite element models allow for more efficient and sustainable design of SWG drives for robotic and aerospace applications.

Ionic Liquids: Advanced Lubricants and Lubricant Additives

by Hong Guo, Doctoral Candidate - PhD in Engineering, RIT, KGCOE Friction between contacting surfaces can be found everywhere, from pistons of car engines to gear boxes of transmission systems of wind turbines. Friction and the resulting wear of the moving components will lead to eventual failure of mechanical elements over extended time. Consequently, friction and wear of mechanical components are responsible for tremendous amount of energy consumption, economic losses, and CO2 emissions. It is reported that around 119 EJ of the world’s energy consumption results from frictional contacts; friction and the subsequent wear represent costs up to 277,163 millions of dollars per year, and result in 8,120 Mt CO2 emissions.

The addition of lubricants between moving components is one of the most effective methods to reduce friction and wear. Although many lubricants with specific functions such as friction-reducing, anti-wear or anti-oxidation are already in widespread use, most of these lubricants contain toxic substances that are harmful for the environment.

Ionic liquids (ILs) are a class of salts that includes positive ions (cations) and negative ions (anions) in their structures. Different from the general salts (such as sodium chloride - NaCl), ILs have low melting points and can stay in a liquid state at ambient temperature or under 100 degree Celsius. They have unique properties, such as negligible volatility, high thermal stability, and low flammability, that make them optimal lubricants and lubricant alternatives. The extra-low volatility makes ILs serve as “green” alternatives to many of the volatile mineral or synthetic lubricants that are currently in industry use; and expands the application of ILs in high vacuum systems.

The outstanding thermal stability of ILs can contribute to their application at high temperature environments under which mineral lubricants are easy to decompose. The non-flammability is of great importance in regards to the lubricant storage.

Figure 1 (right). ILs form ordered liquid-layers between contacting gears.

According to previous studies, the enhanced anti-friction and antiwear properties of ILs are attributed to the boundary IL-films that are adsorbed on the moving surfaces, avoiding direct contact between the two surfaces and reducing friction. In gears, as shown in Figure 1, the anions and cations of ILs will directionally attach to the metal surfaces when ILs are added between moving components, where the charged side of their molecules will settle down on the metal surfaces and the long alkyl-chain side would slide with the motion. The formed ordered lubricant layers will lower the friction and protect the working surfaces from future wear.

Our goal in the Tribology Laboratory in the Mechanical Engineering Department at the Rochester Institute of Technology is to design eco-friendly and high-performance lubricants and lubricant additives to enhance wear and friction behavior of engineering systems. Recently, an eco-friendly ionic liquid, 2-hydroxyethylammonium 22 | The ROCHESTER ENGINEER JUNE 2020

feature article

2-ethylhexanoate (Eet), was synthesized in our laboratory and studied as neat lubricant and lubricant additive to a biodegradable base oil (BO) in a steel-steel contact. Since petroleum-based lubricants are currently widely used in industry, a commercially available mineral-based oil (MOA) was used for a comparison purpose.

Figure 2. (a) Average friction coefficient of steel-steel contact and wear volume of the steel disks after lubricated with different lubricants; (b) 3D profilometer images and (c) 2D profiles of wear tracks on the steel disks after lubricated with BO, 1 wt.% Eet+BO, and Eet. From Figure 2, the presence of the IL in the lubrication system, either as neat lubricant or additive, reduced friction and wear compared to the base BO or the commercially available MOA. Neat Eet presented a significant improvement in friction and wear with respect to BO, with a friction and wear reduction of 65.6% and 95.3%, respectively. Although Eet performed better as a neat lubricant, the addition of just 1 wt.% IL to the base BO not only reduced friction by 16.3% but also decreased the material loss by 10.1% compared to the commercially available MOA. Figure 2(b) and (c) show the 3D and 2D profiles of the wear tracks on steel disks after tests lubricated with BO, 1 wt.% Eet+BO, and neat Eet. Wear scar is negligible after using Eet as neat lubricant, and only some superficial scratches were observed on the worn surface. When Eet was used as additive to BO, not only the width but also the depth of the wear track was reduced with respect to BO. By now, although ILs have attracted considerable attention as effective lubricants and lubricant additives since been explored for lubrication in 2001, research is also needed to find out the stability and efficiency of new families of environment-friendly ILs. The experimental results will provide clear guidelines to the design of new highperformance and eco-friendly ILs for target applications, and will also help engineers design high-performance lubricants and lubricant additives to effectively reduce friction and wear of mechanical components and prolong their service life.

Compared to the currently used mineral oils, the application of these advanced eco-friendly ILs as lubricants or lubricant additives would help the world reduce energy consumption, decrease significantly economic losses and consequently lower carbon dioxide emissions. q

Meet Our Technology Group

The SWBR Technology Group is our firm-wide resource for advanced building scanning and point cloud BIM modeling services.

The firm has always embraced design innovation and has now taken that commitment to the next level with a significant investment for in-house visualization technology. Our three-person team of technology experts employ a combination of 3D laser scanning, virtual and augmented reality, and drone software to create point cloud data. This process results in exceptionally accurate and detailed 3D BIM (Building Information Modeling) models, which can be used throughout the design process.

We have created a design and technology center which includes a gaming T.V. for AR/VR viewing, enabling immersive experiences within designs for our clients and design teams.

These in-house capabilities can eliminate the need for manual scanning, measuring, and hand drawing, saving valuable time for design, and reducing the chance for human error. “We’re creating a ‘Culture of Accuracy’ for our clients,” said Chief Information Officer, Keith Sylvester, who also oversees the group.

Keith, who has been with SWBR for over 20 years, manages all IT systems and is the lead Information Technology (IT) decision maker, responsible for strategy, design, implementation, utilization of technology, and data security.

Laser scan of local campus

Victor Cruz, our reprographics manager who has been with the firm since 1993, has been a Level II Faro Scene Certified and drone pilot since 2016. Drone photography is used to better see conditions that are otherwise inaccessible, enabling greater understanding and attention to detail, during the earliest stages of design. Drone technology provides photography of exterior and roof conditions, capturing existing conditions prior to and after design. Laser Scanning technology provides “point cloud” scans of exterior and interior conditions and measurements, capturing existing conditions prior to and after design with great accuracy.

New to the group, Building Information Modeling (BIM) Manager Peter Foti has expertise and passion for Point Cloud technology, 3D modeling, Revit, laser scanning, and virtual reality. Peter’s expertise with digital scanning and point cloud technology allows us to create precise measurements that are crucial to the project’s success, saving time for designers and billable hours for clients.

“Applying these new technologies strengthens our current design expertise and creates new avenues for growth, improving our services and offering our clients an enhanced customer service experience,” said President Tom Gears, AIA. “We look forward to our on-going use of these technical capabilities, as well as our additional expertise with building energy modeling, envelope performance, and advanced thermal imaging for roofing design.” q

Message from Outgoing MPES President

It has been my honor to serve as president of the Monroe PE Society for these past two years. During this time our organization has continued to evolve and grow as well as show our resilience. We have continued our board of directors’ meetings to the RIT campus and we have added a virtual component, which has continued collaboration between our chapter and RIT. Mathcounts, TEAMS, and the Symposium have all continued to develop with much growth and many improvements along the way.

As I leave this role, I plan to continue to support our chapter as an active member. I’d like to express my heartfelt thanks to the members of the board of directors and the individual society members who have supported me and made it a pleasure to serve as president. Please join me in welcoming the incoming president, Dr. Arthur Reardon, P.E. Dr. Reardon’s two-year term of office will begin on July 1st of this year.

With deep gratitude & respect, Christopher V. Kambar, PE As always, we encourage active membership in the Monroe Professional Engineers Society.

GOLF ANYONE?!!

We are still tentatively planning to have our annual golf outing in June. obviously follow all State mandates and will keep you posted if this needs to be postponed. Because of the potential last-minute decision to have this or not, and various financial hardships many companies will be facing, likely accept “cash (or check) at the door” for any golfers who are ready to get out and see ASPE friends and co-workers in person! We will send an e-mail to our ASPE distribution with details as this gets closer. Or contact

Stay safe, enjoy your WFH time, and we hope to see everyone out and about real soon!

President's Message

I hope everyone’s family and friends are doing well during these difficult times.

As mentioned last month, the annual golf outing and picnic has been postponed. It will be combined with our fall clambake at Ravenwood Golf Club on August 17th. Over the years ASHRAE has benefitted from the generosity of the local community.

Well now we believe it is time to give back. The officers and committee chairs have agreed that 25% of the proceeds raised for the clambake will be donated to Foodlink NY (www. foodlinkny.com). The Corona virus has put a strain on so many, especially those less fortunate than us. Foodlink NY has partnered with Rochester City Schools to provide meals and emergency food boxes to those in need. More details on the clambake and how to donate will follow.

I’d like to thank Mike Hoppe of Daikin Applied for changing his presentation to a webinar and still sharing his knowledge with our Chapter this past April 10. His Webinar was titled “A Different Approach with Cloud Based Controls” and was well attended and informative. On April 29th, the Rochester Chapter joined the CNY Chapter for a presentation by an ASHRAE Distinguished Lecturer, Chris Mathis of Mathis Consulting group.

The webinar was titled “Why Buildings Matter” and discussed considerations to incorporate a building’s energy usage with its function for an occupant’s needs. Again, thank you to both for sharing their time and expertise with us.

YEA (Young Engineers in ASHRAE) also hosted a webinar on Wednesday, May 27th at noon. The topic was psychrometrics and was presented by Al Rodgers of Pathfinder Engineers.

Please continue to check out our website at www.rochester.ashraechapters.org for information on upcoming chapter meetings, current officer list and contact information, chapter newsletters, and more! Also take a minute and like us on Facebook at www.facebook.com/#!/ashraerochester.

Most importantly, please follow the guidelines placed by the CDC and health officials so we may get through this as quickly as possible and put all of this behind us. Please be safe and stay healthy.
