UW-Green Bay has hired two recent alums as faculty members in their Richard J. Resch School of Engineering. The school is part of the College of Science, Engineering and Technology.

Md Rasedul Islam (’20 PhD, Mechanical Engineering) is an associate professor whose research interests include bio-robotics, intelligent systems and control, and automation.

Assad Uz-Zaman (’24 PhD, and ’17 MS, Mechanical Engineering) is an assistant professor who researches robotics, control robot motion planning, industrial automation, and sensor fusion.

Habib Rahman, Richard and Joanne Grigg Professor, mechanical engineering, was UWM advisor for both graduates.

College leaders visit partner universities in Taiwan to explore expanding agreements

Representatives of the college recently visited two universities in Taiwan – Chang Gung University (CGU) and Chung Yuan Christian University (CYCU) – with an eye toward expanding academic degree program collaboration, injecting more research opportunities into those programs, and exploring deeper industry-academic collaboration.

Andrew J. Graettinger, associate dean for research, Dah-Chuan Gong, scientist, and Jaejin Jang, department chair and associate professor, both in the industrial & manufacturing engineering department, made the trip. Gong, a former dean of the College of Management at CGU before coming to UWM in 2022, was instrumental in organizing the trip.

New program proposed with CGU

A proposed new degree program being discussed with CGU is a 3+2 program. Students would take three years of undergraduate business management courses in Taiwan and, during their first year at UWM, they would complete their undergraduate coursework, but in engineering. They would receive their bachelor’s degree in business management from CGU and then continue their studies at UWM to receive an MS in engineering from UWM.

“The two degrees stand alone, which is rather unique,” Graettinger said. “We have a path forward that suggests it would work.” This potentially would result in 20 or more new UWM master’s degree students a year, he said.

The college and officials at CGU have signed a memorandum of intent to establish the proposed 3+2 accelerated degree program.

The existing partnership programs with CGU includes:

  • a dual master’s program between the college and CGU’s College of Management
  • a dual master’s program between the college and CGU’s College of Engineering
  • a non-degree program for undergraduates

Programs with CYCU growing

At CYCU, the 2+2 undergraduate program has grown from 20 in a cohort to 26. The 2+2 program with CYCU is a dual degree program that began in 2023 and offers students the opportunity to study in Taiwan for their first two years and complete their final two years at UWM.

Tzu-Yun Yen, a senior in electrical engineering, is a student from CYCU in the 2+2 joint program with UWM.

Students in computer science, computer engineering and electrical engineering are eligible. A dual master’s program in electrical and industrial & manufacturing engineering has been ongoing since 2018.

Also, the UWM team pledged to provide students in the existing 2+2 program with opportunities in UWM engineering and computer science research and financial support through the Support for Undergraduate Research Fellows (SURF) program.

Tzu-Yun Yen, a senior in electrical engineering, who is participating in CYCU’s 2+2 program, shared, “In the classroom at UWM you will meet students from different countries. The good thing about studying at UWM is that the environment will help you find out your future goals sooner.”

Aligning research for more student involvement

The proposal falls in line with another aim – to identify pathways to increase collaborative research in both partnerships.

“We have good research topic alignment with both CYCU and CGA,” Graettinger said. “We both have faculty who are active in the areas of medical devices, electrical engineering, industrial optimization, and membranes and filtration, for example. We’re trying to cultivate those.”

For the first step, UWM will begin working on a proposal that will be submitted to International Network-to-Network Collaborations (AccelNet) to enable joint research. That would open the way for graduate students to also conduct research as they work on their dual degrees.

There also was interest from all parties to grow the partnerships’ research ties in tandem with industry in both countries, Gong said.

Students currently enrolled in partnership programs have had work opportunities at Foxconn in southeast Wisconsin. But the team is exploring additional possibilities.

During their trip, UWM representatives learned about CGU’s semiconductor program and its industrial support and visited the semiconductor clean room on the campus.

At CYCU, the UWM team toured the R&D Center for Smart Manufacturing (SMC), a facility that is introducing smart manufacturing concepts into the injection molding industry in Taiwan. Graettinger said the teams discussed promoting the SMC, led by Professor Shia-Chung Chen, to the sector industries in the Milwaukee region.

Currently the college’s programs with the two Taiwanese universities involves about 50 students, both undergraduates and master’s students enrolled in one of the dual programs at UWM. Students benefit by receiving an international education, access to research and internship and career opportunities.

Nosonovsky blends surface science with machine learning to predict beach contamination

A interdisciplinary UWM research team, including Michael Nosonovsky, professor, mechanical engineering, collaborated to determine how to predict E. coli outbreaks at beaches more effectively.

Their goal was to identify the key sand conditions linked to E. coli growth and determine the best machine-learning method to predict these conditions.

Michael Nosonovsky

Their findings were published in an article that appeared in a 2024 volume of the journal Surface Innovations.

E. coli bacteria are often used as indicators of water contamination, and elevated levels are one of the main reasons for beach closures. The researchers focused on how the physical and chemical properties of sand influence the survival and spread of these bacteria.

“Bacterial contamination of beach sand poses a public health problem,” Nosonovsky said. “So, it’s important to establish correlations between surface properties of sand and biocontamination, allowing us to predict and prevent the latter.”

Nosonovsky, whose expertise is tribology – the study of surfaces and friction – said that how sand interacts with water plays an important role in bacterial growth.

The work was conducted using data from Bradford Beach on Milwaukee’s lakefront. The researchers tested five different machine learning techniques and concluded the artificial neural network (ANN) technique outperformed other models in predicting E. coli concentrations.

The ANN model identified three critical factors predicting E. coli levels in sand:

  • the state of sand, including parameters such as moisture content, pore size and the zeta potential – the difference in potential between a particle’s surface and the liquid it is suspended in.
  • processing temperature
  • the contact angle, which measures how easily water spreads across its surface. A special methodology was developed to measure the water contact angle of sand, Nosonovsky said.  

The study shows the great potential of “tribo-informatics” – a new field that combines tribology, with data science and machine learning methods – to solve various problems, he said. The technique can be scaled up and applied to other beaches. Other team members were Md Syam Hasan (’22 PhD, mechanical engineering); Marcia Silva, former manager of UWM’s Water Technology Accelerator, and Alma Nunez.

Shi’s work is transforming traffic data into road safety solutions

man looking at camera with traffic in background

Every time you drive a vehicle, one aspect of your safety comes from something you have little control over – other drivers. What if risky driving behaviors could be tracked as they are happening and immediate warnings delivered to drivers nearby?

“The idea is that drivers may be able to take a defensive stance to avoid crashes if they could be alerted to risky driving in their vicinity,” said Tom Shi, an assistant professor of civil & environmental engineering. “Or police could discover where the most dangerous locations are and intervene.”

Members of Shi’s lab have completed the first step in a multi-pronged data science project aimed at improving road safety by analyzing video for predictive modeling.

Making Waves of Impact
A transportation engineer uses camera data and AI to predict where drivers exhibiting dangerous behaviors are.

Since he was looking for traffic data, Shi partnered with the UWM Police Department which maintains a large network of surveillance cameras pointed at roadways all around the campus.

Extracting answers from data

The lab members began by began by collecting the incidence of risky driving behaviors on certain stretches of road or at intersections at various intervals. Then, they built a digital map of what happened using a detectionalgorithm they developed.

“We use deep learning methods to extract characteristics from vehicle footage, and these characteristics help us identify distracted driving behavior, such as using a phone or taking your eyes off the road,” Shi said.

A video of one of the researchers’ digital maps shows cars as 3D boxes moving along the street where pedestrians are visible, marked in yellow.

The algorithm provides the time-stamped location of the objects and their GPS coordinates, the object’s speed and the size of each – whether it’s a car, truck or even bike.

“Given all those parameters, we can use data science to answer questions like, “How often does speeding occur and under what circumstances?” Shi said. “The lab members assigned a score from the safest conditions to the worst scenarios. So, the algorithm is using the data to pick out the unsafe anomalies.”

An unsafe pedestrian hotspot

From traffic footage that spans Maryland Avenue from the Student Union to Edgewood Avenue, a long corridor that includes three intersections, the researchers have used the modeling to help them understand and analyze the interaction between the pedestrians and vehicles.

For example, Shi’s students developed a video that re-constructs traffic moving along Maryland Avenue in front of Hartford Elementary School from data collected by a camera mounted to the northeast corner of Lapham Hall.

The group found that drivers approaching the crosswalk there often follow the car in front of them very closely in order to avoid stopping when pedestrians are present. That leaves pedestrians wondering who will stop and who won’t.

The final step

Shi said his work includes both the data science needed to clarify traffic problems and the development and testing of new technologies to address them.

The final step in this project will be to create an intervention that would send out a warning of driving aberrations happening at a location in real time.

Although the warning product has not yet been created, one idea is an audible signal on a driving app, he said. The research has the potential to lead to new products.

Further in the future, for example, the warning product can leverage the existing cellular network. This technology is called cellular-vehicle-to-everything (C-V2X) communication.

“We do plan to install a C-V2X roadside unit at the Hartford-Maryland intersection,” Shi said. “Currently, it requires the vehicle to have a C-V2X onboard unit to receive the command we broadcast. In the future, this will be equipped on vehicles by the manufacturer.”

SAE magazine published an interview with Rahman about rehab robotics

Habib Rahman, professor, mechanical engineering, was interviewed for a Q&A that recently appeared in Tech Briefs magazine on his recent research building a platform that would make remote physical therapy available to stroke patients.

Each month, the engineering magazine, put out by the SAE Media Group, features a researcher who has done innovative research.  

Rahman developed a portable, assistive robotic arm, called the iTbot, that allows stroke patients to receive physical therapy without leaving their homes.

In the interview, Rahman explains how the assistive arm can adjust the right tension for a patient, which methods the arm employs to measure pain-free range of motion, what information a digital twin can give the therapist, and why a therapist is always a part of the treatment’s platform.

Transforming the electrical grid – and conquering power outages – starts with Cuzner’s ‘building blocks’

man staning in front of equipment

Electrical outages have become a common occurrence around the globe – and also in Wisconsin, said Robert Cuzner, professor of electrical engineering. “I’ve kept track at my home and I’ve been without power for at least 100 hours in the last year.”

With a rise in extreme weather, an ever-growing demand for energy, and an aging electrical grid, how can the U.S. fix its infrastructure and boost reliability without starting from scratch?

The answer, said Cuzner, is microgrid technology. Microgrids are power sources for a limited area, such as a military base. They integrate different kinds of energy, such as diesel generators, solar cells, wind turbines, fuel cells and battery banks to supply the necessary electricity storage, whether connected to the main grid or operating as an “island,” serving as backup power for the immediate vicinity it serves.

Cuzner views microgrids as a way to transform the old grid into an automated modern system. Microgrid components “talk” to each other, making them much quicker at detecting defects before they lead to a blackout.

However, because microgrids are smart, they are complex, making them expensive to operate. Cuzner has pioneered an idea that would clear the way to for microgrids to thrive commercially. He proposes breaking them down into “building blocks,” or smaller units of microgrid components, called nanogrids.

The background on microgrids

One reason microgrids aren’t widely used yet involves equipment compatibility, Cuzner said.

“You’re trying to merge the old infrastructure with the new equipment of the microgrid, where no uniform standards exist,” Cuzner said.

Finding the equipment needed to integrate renewables is one example, said Mark Vygoder, a doctoral student and longtime lab member. Cuzner’s lab members have been working with large U.S. military bases in Europe that already use microgrids to address grid insecurity but are grappling with costs related to knitting together unstandardized equipment.

“It’s a bit like the Wild West where you can buy devices from different vendors and all the products are a little bit different,” Vygoder said. “So, it becomes quite costly when you have to hire a service provider to sort that out for you. When the microgrid operates independent of the grid, all those different components need to coordinate and communicate.”

Mark Vygoder (from left), Rob Cuzner, and Andrew Eggebeen (’23 PhD, computer engineering) visit the U.S. Rota Base’s solar farm in Andalusia, Spain. Vygoder is a UWM PhD candidate in electrical engineering. Eggebeen currently works for Milwaukee Tool.

UWM expertise in power distribution

Cuzner, an expert in power controls, conversion and distribution – the areas of vulnerability in microgrid technology – stands at the center of UWM’s reputation as a leader in both energy storage and electric grid technology.

Cuzner’s lab is a lead partner in the GRid-connected Advanced Power Electronic Systems (GRAPES), a national industry/university research center that aims to accelerate insertion of power electronics into the national grid.

Cuzner, Vygoder and Andrew Eggebeen, a recent PhD graduate in computer engineering, who worked in Cuzner’s lab, visited three U.S. bases in Europe in the summer of 2023 to get a first-hand look at how these microgrids are being implemented and their limitations.

“One thing we found was that these bases are very large and spread out, leading to transmission problems,” Cuzner said. “In one case, the solar array is several miles outside of the base.”

To solve the problem, Cuzner and his colleagues at the Naval Post Graduate School in California developed a “zonal distribution concept” – essentially breaking microgrids down into less complex units, called nanogrids.

Cuzner has been working with researchers at the Naval Post Graduate School (NPS) in California, who are leading the project. The goal is to simplify the architecture of microgrids, while also increasing their ability to diagnose problems and communicate autonomously. The team includes Douglas Van Bossuyt, NPS associate professor of systems engineering (far right), Cuzner, second from right, Giovanna Oriti, NPS professor of electrical engineering (center), Ron Giachetti, NPS professor of systems engineering (left of Oriti), and Andrew Eggebeen (left of Giachetti).

What is a nanogrid?

Cuzner’s background is in the conversion of Navy shipboard power generation to electrical distribution. Such architecture features damage-control zones: When the power goes out in one part of the ship, the system reroutes itself using smart switchgear and continues to operate with only the affected zone shut down.

Nanogrids can be strung together within the microgrid itself, improving overall smart capabilities. And they can be added one at a time, easing the cost burden of a microgrid.

Cuzner and his team are researching the best ways to standardize components supplied by commercial vendors and ensure “grid-edge inter-compatibility,” which means that even components supplied by different vendors can work and play well together.

“If smart components of a nanogrid are standardized,” Cuzner said, “it can become a ‘plug and play’ building block that can be produced cost-efficiently.”

UWM’s microgrid ‘sandbox’

To work out the details of nanogrids, Cuzner’s lab members have built a fully functional microgrid at the University Services & Research building near UWM’s Kenwood campus. Since 2021, the lab has been building an energy distribution system with smart metering and controls, giving them an experimental sandbox.

Joseph Lentz (’23 MS electrical engineering), left, and doctoral student Mark Vygoder display a portion of UWM’s microgrid, which is housed at the USR building. The lab members are working on the equipment needed to amplify the nanogrid’s smart communication. Routing power through two different AC busses in their system allows them to test with two different nanogrids, either running them independently or connected to the larger system.

The researchers can now observe how a microgrid responds under varying conditions, quantify how commercial components monitor microgrid data, and then simulate in real-time a full-scale system that interacts with real control hardware.

“With our microgrid, we can simulate equipment that is on the grid, test it at scale, quantify the ‘grid-edge’ where everything comes together, and figure out how to improve performance,” Cuzner said. “That’s something no one else has done yet.”

In 2023, they worked with a local company, Badger Technologies, to install, test and integrate a battery energy storage system with the UWM microgrid. In addition, UWM’s microgrid includes a solar array, one wind turbine, two natural gas generators and a smart switch that could connect it to the national grid.

The college is currently exploring ways to secure federal funding to turn the UWM microgrid into an industry-collaborative lab with a 1,000-13,000-volt testing facility. Such a facility would attract industry, quicken the pace of new microgrid technology and would include research on electric ships and aircraft.

Power distribution and controls in focus

Nanogrids also improve control of the flow of electricity if connected to the grid.

Control refers to how the existing grid meets demand. Higher than normal demand for electricity could cause a blackout, but so could a glut of power to the grid from renewables.

Another benefit of nanogrids is that the controls can be built from the “bottom up,” Vygoder said, giving nanogrids the ability to speedily compensate for power disturbances.

Southeast Wisconsin is the perfect place to develop this commercial potential with its cluster of companies related to energy, power and controls. UWM is at the epicenter, with longstanding research partnerships with industry leaders including Eaton, Rockwell Automation, Leonardo DRS, and Johnson Controls.

So far, the U.S. Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC) has funded Cuzner’s collaboration with the Naval Post Graduate School.

Most recently, this led to Cuzner receiving funding from Office of Naval Research to develop a “digital twin” approach to study how nanogrid components respond to a wide range of both normal and damaged scenarios.

AI and nanogrid decision-making

Digital twins rely on artificial intelligence to improve communication among the smart components of both micro and nanogrids. It’s the next step in the integration research.

When paired with machine learning, AI could potentially allow microgrids and nanogrids to teach themselves what leads to a breakdown and autonomously decide what to do when they detect trouble brewing.

For this research, Cuzner has consulted with Zhen Zeng, UWM assistant professor of computer science, who is an expert in digital twins and cybersecurity. Zeng is co-advising computer engineering students who are helping in Cuzner’s lab, bringing together power/energy and computer engineering in the college.

“When we feed a lot of information into an AI model, the model can quickly tell you what is going on in the system,” said Zeng. “We try to understand which situations we would need to consider when building cyber-protection into the design,” she said.

UWM’s master’s in data science ranked one of the best

Fortune magazine has ranked UW-Milwaukee’s Master’s in Data Science program as one of the best in the country, landing at No. 25. UWM’s program also was ranked No. 15 among the most affordable programs nationwide. UWM is the only program from Wisconsin on either list.

UWM’s data science master’s degree is a 12- to 16-month program, which can be done full- or part-time, starting with a bachelor’s degree in any major. Courses from business, engineering and computer science are featured prominently.

The program was established with support from the Northwestern Mutual Data Science Institute, a partnership among Northwestern Mutual, UWM and Marquette University which aims to help make southeastern Wisconsin a national hub for technology, research, business and talent development.
