In graduate student Kenny Nyirenda’s home country of Zambia, access to clean water sources can be challenging, especially in remote areas.

That is why he has committed his graduate research as a Fulbright scholar at Washington State University Tri-Cities to improving access to clean sources of drinking water and finding solutions to prevent water pollution.

The Fulbright Scholarship allows students and young professionals to undertake international graduate study, advanced research, university teaching and primary and secondary school teaching worldwide. The prestigious program awards approximately 1,900 grants annually in all fields of study and operates in more than 140 countries worldwide.

Kenny Nyirenda with UK Groundwater Project

Kenny Nyirenda completes some work with the UK Groundwater Project.

As part of his Fulbright program, Nyirenda is studying under Yonas Demissie, assistant professor of Civil and Environmental Engineering at WSU Tri-Cities, to look at the impacts of mining on groundwater resources, as well as how climate change is impacting groundwater resources.

“Because of what is happening in terms of climate change and in terms of pollution, people are now resorting to the ground for their water sources,” he said. “Groundwater is often a clean source of water and is readily available in the ground, although it can get depleted and polluted especially by anthropogenic activities.”

Nyirenda said Zambia is largely known for its mining, which puts pressure on water resources as a result of excessive pumping and pollution from the activity.

“We want to make sure that this resource is protected, and many surface water bodies are drying up in some parts of the country due to prolonged dry seasons attributed to climate change,” he said. “There is fresh water available in the ground and we need to make sure we are protecting the resource, especially in these areas that are prone to climatic change.”

Currently, as part of a graduate seminar, he is reviewing the data and literature on the impacts of mining on groundwater in Zambia and around the globe, assessing the potential of acid mine drainage and its impact on groundwater sources.

“What they are mining in Zambia are mainly base metal sulfide-rich mineral deposits, which have the potential to generate acid when exposed to air, moisture or rain water,” he said. “Once that acid is generated, it becomes a nuisance because it spreads into the environment together with the dissolved heavy metals it carries and ends up in groundwater.”

Solving the issue of access to clean drinking water and preventing pollution from occurring within not only his home country, but throughout Africa, he said, could solve many more problems throughout the continent.

“Many diseases that are prevalent in Africa stem from consumption of poor quality drinking water,” he said. “If you sort out the problems with water, you sort out problems with most of Africa. We need to figure out how to protect the resources that we have, as well as improve access to good quality water across Africa.”

Geophysical survey of groundwater - Kenny Nyirenda-1

Kenny Nyirenda participates in a geophysical survey of groundwater.

Nyirenda said he has never personally suffered from lack of access to clean drinking water, as he grew up in a military barrack where his father served in the military. As a result, he and his family were provided with water and electricity. Across rural parts of Zambia and in other parts of Africa, however, people may not have regular access to the same resources.

“For one, many might not have the knowledge to know whether a water source is OK,” he said. “Additionally, because there are natural sources of pollution, people may collect water thinking that it is of good quality, when in fact, there may be serious issues with it.”

Nyirenda said he plans to take the research he develops through WSU Tri-Cities and inform people, as well as implement changes, in his home country. His home university, The Copperbelt University, was selected by the World Bank as an Africa Center of Excellence in Sustainable Mining. One of its aims is to promote a balance between environmental sustainability and mine production. The pairing of his Fulbright experience at WSU Tri-Cities with the resources afforded to him at his home university will allow him and his colleagues to make a true difference when he arrives back home.

“One of the great things about the Fulbright program is the mutual understanding between the two countries that I can take my work back home to implement positive changes,” he said. “When I go back home, my network here will still be there as a result of this Fulbright experience. My work doesn’t have to end here. We will still be in touch to communicate about developments and regarding new opportunities once I return home.”

Nyirenda hopes to work with the United Nations Environment Programme or United Nations Water to bring about positive change regarding water infrastructure and policies surrounding the resource in his home country. From there, he hopes to become a politician so he can help lead initiatives that will improve access to good quality water.

“Politicians have the opportunity to be more powerful to implement most of these innovative ideas regarding water access and policy,” he said. “I want to use this influence to implement these ideas.”

In a cold, dimly blue-lit room, a strange human–animal hybrid paces before the entrance to a fiery red cave. When the “Huminal” senses a viewer approaching, it stops, turns its head to stare at the visitor and emits its own red-hot glow. The viewer must then decide how to respond to the apparent challenge: continue toward the creature or retreat.

WSU Tri-Cities fine arts professor Sena Clara Creston and engineering student Gordan Gavric work on the "Huminal," an interactive robot that responds to its environment.

WSU Tri-Cities fine arts professor Sena Clara Creston and engineering student Gordan Gavric work on the “Huminal,” an interactive robot that responds to its environment.

The Huminal is an interactive, kinetic sculptural installation featuring an autonomous, mobile robot that senses and responds to changes in its environment. Created by an interdisciplinary team at Washington State University Tri-Cities, it incorporates research and techniques in fine arts, design, electrical and mechanical engineering and robotics to provide a unique platform for exploring the relationship between humans and machines—and, it turns out, between artists and engineers, too.

Two years in the making and nearing completion this month, The Huminal is the third and most complex art-machine designed and built in as many years by fine arts professor Sena Clara Creston in collaboration with WSU engineering students and faculty. It debuted recently to rave reviews at a robotics exposition for employees of Pacific Northwest National Laboratory in Richland, where Gordan Gavric, a key member of the Huminal development team, is an electrical engineering intern.

“The feedback we’ve gotten so far is really great,” said Gavric, a senior in engineering and president of the WSU Tri-Cities Robotics Club. “People recognize it’s a robot, but at the same time they’re a little creeped out. How do people want to interact with a creepy robot?”

Designed to pique curiosity along with uneasiness, the Huminal is about the size and shape of a large dog and covered with white plastic discs resembling scales or fur. Its four jointed legs give the appearance of walking as it rolls in an elliptical path outside its apparent den.

Multiple internal sensors, a camera and a small Raspberry Pi computer communicate with microcontrollers across two electronic systems to direct the robot’s movements and trigger the pulsing red LED lights in its chest. The steady hum of its heart—two 8.6 volt motors—is interrupted only when a sensor detects nearby movement. At that point, the Huminal is programmed to stop in its tracks, turn its head to face the approaching object and transmit its warning glow.

“I look forward to seeing how more people react to it,” Gavric said. “Is it alive? Is it human? The mystery is unnerving and it’s this uneasiness that Sena is trying to exploit.”

A corporeal experience

new media artist, Creston builds interactive art-machines to create a corporeal experience for viewers. Her artworks invite people to engage with machines and familiar materials in unfamiliar settings and ways. Environmental impact and social consciousness are frequent themes.

WSU Tri-Cities fine arts professor Sena Clara Creston and engineering student Gordan Gavric work on the “Huminal” at WSU Tri-Cities.

“Some people get really aggressive with the work and some are really careful with it,” she said.

By enabling viewers to choose their response to her art, she hopes to help them understand other ways they affect the wider world.

From the haunting Huminal to the satirical Machinescape—an immersive environment of post-consumer electronics—to the dreamlike Umbrellaship—a land-roving, steampunk-style sailboat—much of Creston’s art employs fantasy while exploring intersections between the natural and the man-made.

“Part of it is movement, part of it is response, part of it is material and part of it is social engagement,” she said.

She will talk about her innovative artwork at 1:00 p.m. Saturday, Sept. 16, as part of TEDxRichland events at Uptown Theatre in Richland, Washington.

To create the Huminal’s skin, Creston cut up dozens of discarded plastic water bottles—familiar and somewhat controversial objects that connect the organic and inorganic.

“Many people across the world live with an unsafe water supply, yet we think of water as the source of life and the source of health and wellbeing, and water bottles deliver that,” Creston said. “However, the water bottle itself is not biological or biodegradable—it’s inorganic and it’s not going away. So the material itself becomes this questionable component.

“How do we actually feel for the inorganic and how do these things elicit responses?”

Collaborating in uncommon opportunities

Giving form to Creston’s layered ideas and complex inventions often requires more technical skills than she possesses. So for the past 10 years, she has been learning and implementing modest means of physical computing and mechanical engineering.

“But, as my mentor explained, I didn’t need to learn how to do everything—I needed to learn how to collaborate,” she said.

Fortunately, interdisciplinary collaborations are strongly encouraged and available at WSU. Engineering professors Changki Mo at WSU Tri-Cities and Charles Pezeshki and Jacob Leachman at WSU Pullman recognized the uncommon opportunities Creston’s projects offered their students and wove them into their coursework.

“Her projects presented the perfect combination of an interesting customer, an achievable design and the monetary scope to take some risks in a shared learning experience,” Pezeshki said.

Students in Pezeshki and Leachman’s junior-level design classes worked remotely with Creston to create The Umbrellaship and Machinescape. The installations were designed, like The Huminal, to question the relationship between humans and their perceived environment.

Eric Loeffler, a May graduate in engineering who constructed the Huminal’s aluminum frame, said he and other students on the project gained a variety of valuable hands-on experiences not usually available to undergraduates.

For example, Loeffler learned new design software applications that he can use in his master’s degree program, and he expanded his welding skills to include aluminum materials.

“There were a lot of new things to work with from an engineering standpoint, and getting the chance to interact with Sena as a client was huge, too,” he said. “There’s really not a class that teaches you how to interact with a person who has their own particular wants, ideas and capabilities. That experience will definitely be useful in the future.”

Shared purposes, different approaches

“Some people might think engineering and arts are very different, but artists and engineers kind of have a shared purpose,” Gavric said. “They create things. They bring things into existence, and have ideas and concepts that they want to make. The difference lies in medium and motive. An engineer might design a circuit board to save a life, while an artist might paint a picture to change a life.”

“Working with Sena, I kind of opened up to ‘why are we doing this this?’ Oh, it’s for the aesthetic, or it’s for trying to get the point across.”

Gavric admits, “There’s no way I ever thought I’d be working on a robot for an art project.” But even before Creston finished presenting her concept sketches to the Robotics Club, he was hooked.

“It intrigued me immediately as an interesting concept and totally something new. There was a lot of back and forth on what we could do with the given technology and funding, and a lot of compromises, abstractions and problems that were solved. It was a rare opportunity. I’m glad I did it.”

Loeffler especially appreciated the chance to think outside the box.

“I really enjoyed the opportunity to collaborate and come up with different ways to solve a problem,” he said. “I think we’re fairly close to what Sena originally envisioned, with the aesthetic and the function she was looking for, and that’s very satisfying.”

The interactive art machine projects encouraged the engineering students to consider their role as engineer, inventor, creator and artist, Creston said. As they grew comfortable working on art projects and expressing their own creative ideas, they sought new collaborations with artists and invited them to participate with the Robotics Club.

Some of the rising engineers began working with fine art students on interactive media projects and even created an interactive art installation of their own, called Lux Flux. The large-scale ceiling installation was designed to sense when a viewer entered a darkened hallway and to send a river of light shooting along the ceiling.

“The project was completely collaborative with a fluid crossover between artists and engineers filling in the rolls of conceptualizers, designers and technicians as needed,” Creston said. “It was beautiful to see.”

Creston is now working with a team of mechanical engineering design students to develop their collective senior year project. Her creative and scholarly work has received financial support from the WSU Office of Academic Affairs, the Department of Fine Arts and the School of Engineering and Applied Sciences, as well as a chancellor’s seed grant to provide tools and materials and a project grant from Artist Trust.

The interdisciplinary projects align with the WSU Grand Challenges goal of improving education. They further the University’s Drive to 25 efforts by delivering innovative teaching, community outreach and transformative student experience.

The United States power grid is connected by more than 450,000 miles of high-voltage transmission lines to provide electricity to more than 300 million people. But as the saying goes, with great power, comes great responsibility.

Yousu Chen – PNNL

With the increase of renewable energy sources, the growth of the increasingly complex system and increases in terrorist threats, engineers have to come up with new methods to protect the power grid.

Yousu Chen (WSU Tri-Cities MS, environmental engineering), staff research engineer at the Pacific Northwest National Laboratory, is using high-performance computing techniques to safeguard the electrical grid against potential threats and outages.

“The power grid is the largest man-made machine in the world,” he said. “It is the most important infrastructure, and we need it daily for almost all of our daily activities. I’m always eager to know what I can do in this fast-growing area to solve new problems.”

During his time as a student at WSU Tri-Cities, Chen got his first internship at PNNL. He also learned skills in simulation and modeling that have proven invaluable to his career.

He has been involved in the Institute of Electrical and Electronics Engineers, increasing opportunities for current students.

Solving problems before they happen

Chen‘s work focuses primarily on modern computing techniques that both simulate potential hazards and provide ways for monitoring information within the grid. Through the advancement of high-performing computing techniques, he and his team at PNNL are developing simulations to predict and combat problems before they occur.

Chen’s computing systems utilize complex algorithms to measure power flow, identify potential problem areas, simulate possible outcomes if there were to be an outage or a catastrophic event, as well as provide solutions in how to deal with those potential problem areas.Power pole

“For example, if we want to evaluate the impact of newer smart grid technologies on the power grid, we use our simulation techniques to prepare for the event before we apply those new technologies to the grid,” he said. “Using our simulation, we could determine how that issue would impact the grid, and as a result, how we can prevent that from occurring.”

Chen said he and his team are always developing newer computing techniques to run simulations at a faster rate, which will be crucial in the event of a major outage or disruption.

“Some systems will take minutes, depending on the system, to run a limited number of contingencies,” he said. “My code is able to run 1 million contingencies in less than 30 seconds. That is a major achievement.”

With all of the data generated through advanced computing methods, Chen and his team are also always looking take the massive data caches and efficiently turn them into something usable and visual.

“Because high-performance computing systems can create a lot of data, it is challenging to digest that data in the short-term,” he said. “We develop advanced visualization tools, which allow us to view that data in real time and provide a quick response for potential events.”

Giving back to the future of engineering

Even though Chen has achieved much in his career as an engineer, he has used his position to increase opportunities for disseminating knowledge of his field into the community, as well as create pathways for other students to follow in his footsteps.

Chen realized early in his higher education career just how valuable mentorship and extracurricular learning experiences could be to his own growth as an engineer. In addition to utilizing university resources to connect him with an internship at PNNL, he also sought advice for how to improve his resume, his interview skills and more through the university’s career development center. After landing a full-time position of his own at PNNL, he wanted to keep paying forward what he learned, using his connections in engineering and computer science to provide resources and mentoring to aspiring engineering students.

Chen has since volunteered his time through a variety of capacities for the Institute of Electrical and Electronics Engineers. He serves as chair for the IEEE’s distinguished lecture program and formerly served as the regional representative of the IEEE Power & Energy Society and the regional chair for the IEEE Power Energy Society’s scholarship plus program. He also serves as the editor for two professional journals where he helps edit and review articles for publication pertaining to the smart grid.

As a result of his efforts, Chen was recently awarded the Institute of Electrical and Electronics Engineers’ Leadership Award for the contributions he has made to IEEE activities and the leadership he’s displayed through IEEE at the local, regional and national levels. In a congratulatory letter, Wai-Choong Wong, vice president of the member and geographic activities at IEEE, stated that Chen has set a great example in carrying forward the goals and objectives of the IEEE MGA board.

Chen said he is grateful for all he learned in his education at WSU Tri-Cities, as well as what he has been able to accomplish since then by means of his work at PNNL, as well as through his involvement with the IEEE.

“These opportunities changed my life,” he said. “I’ve been fortunate to accomplish a lot in my career as an engineer and I believe it is my responsibility to not only increase the capabilities of the power grid, but to also increase the potential for the world’s future engineers who will solve many of these energy-related problems.”

Technologies to be implemented in Uganda this June

RICHLAND, Wash. – Three teams of engineering students at Washington State University Tri-Cities designed technological advancements that will address challenges pertaining to farming, education and agricultural business in rural communities in Uganda.

The projects were part of the students’ capstone engineering courses at WSU Tri-Cities where students are tasked with completing a year-long project that integrates many of the components of the students’ foundational engineering and related courses to solve either a real-world or simulated problem.

Scott Hudson, WSU Tri-Cities professor of electrical engineering (left), helps his students solder a wire to a strip of solar-powered lights that the students designed for a remote community in Uganda. The lights will be implemented in the Kagoma Gate Village in Uganda this June.

The projects for the Ugandan communities include:

  • An aquaponic system that incorporates minimal water, fish and a growing medium to produce a recyclable and sustainable agriculture system
  • A solar-powered lighting system that will allow for additional educational instruction time in the evening and during other minimal daylight hours
  • A solar-powered mushroom dryer that preserves a local mushroom crop that will increase economic opportunity for the local community

Scott Hudson, WSU Tri-Cities professor of electrical engineering, and Messiha Saad, clinical assistant professor of mechanical engineering, serve as faculty mentors and advisors for the three projects, which were funded by Hudson on behalf of The Giving Circle. The Giving Circle is an all-volunteer, nonprofit organization based in Saratoga Springs, N.Y., which provides services and builds schools, sanitary facilities and more, to help disadvantaged communities around the world.

Hudson will also accompany a Giving Circle team to Uganda this June to help implement the new technologies to ensure their longevity and success.

The students spent their first semester predominantly coming up with a design for their projects and their second semester physically building the structures.

“What is great about these projects is that they will be directly implemented into communities that have a dire need for these technologies,” Hudson said. “Students are using their skill in engineering to design products that will serve an immediate need for a deserving community across the world. They’re solving real-world problems that will have a lasting impact.”

Aquaponic system for food sustainability

The Kagoma Gate Village in Uganda is located far from urban areas and utilities and is considered largely “off the grid,” Hudson said. Many people in the community don’t have access to their own farmland or can’t afford it, and water is in limited supply. An aquaponic system, which recycles water and fish waste to fertilize growing plants in the system, while allowing the fish to breed and then act as an additional food source, is a crucial technology that will do a lot of good, Hudson said.

WSU Tri-Cities engineering projects for Uganda - aquaponics

The WSU Tri-Cities student electrical engineering team poses with their aquaponics project that will be implemented this June in the Kagoma Gate Village in Uganda.

The WSU Tri-Cities student electrical engineering team, composed of students Amjad Al-Shakarji, Gabriel Fuentes, Trevin Schafer and Daniel Cain, had a lot of obstacles to overcome with their design, as many of the materials had to be inexpensive and either available in Uganda or easily shippable to the site. The team also had to conduct a tremendous amount of research, considering their backgrounds were limited in botany, hydrology, etc.

“It was an incredible learning process,” Schafer said. “We’re obviously not hydrologists or mechanical engineers, but we made it all work. A ton of our decisions in the design and construction were based off of research and collaborative ideas. It also helped that we worked really well together.”

The team’s design required the use of solar panels and battery storage, which is where the students’ skills in electrical engineering came to play. The students also developed an electronic system that allows them to monitor the effectiveness of the system remotely and track their data.

WSU Tri-Cities engineering projects for Uganda - aquaponics

The WSU Tri-Cities students’ aquaponics system utilizes a solar-powered pump to pump tilapia fish waste and recycled to plants that are planted in an above bin. The student’s design will be implemented in the Kagoma Gate Village in Uganda this June.

The way the team’s design works is as follows:

  1. Plants are planted in clay pellets atop the apparatus, where water is circulated to the plants via a solar-powered pump
  2. Tilapia fish live in a water tank and their waste is distributed to fertilize the plants growing at the top of the apparatus
  3. The fish then double as a food supply source, as they are native to Uganda and are easy to breed

Schafer said overall, the system uses far less water than that of traditional farming methods.

“The main reason we chose this project as our final engineering capstone project is that it truly provides one of the best resources for the people of Uganda,” he said. “It may not be as heavy in electrical engineering as some of the other student projects, but this project will certainly do a lot of good.”

Al-Shakarji said the project has presented the team with significant challenges, but great rewards.

“It’s been challenging to add the component of having to keep something alive, but it’s something that the people in Uganda will find of real value,” he said. “It’s also something that can be easily expanded. Using a manual that is provided by our team and components that may be easily shipped to the country or purchased locally, anyone can recreate this system. The sky is the limit for expansion.”

Solar lighting for additional educational hours

The Kagoma Gate Village has no access to electricity, which limits the number of hours that are available to provide educational instruction, activities and more. That is why a WSU Tri-Cities student electrical engineering team has partnered to create a solar lighting system that will provide more educational hours to the villagers’ days.

The WSU Tri-Cities student electrical engineering team poses with their solar lighting system (above) that will be implemented in the Kagoma Gate Village in Uganda this June.

The team, composed of students Pierce Jones, Daniel Deaton, Steven Goulet and Richard Dempsey, are creating a lighting system that will provide the same level of light as a standard U.S. office building and has the capability to store enough energy for at least two hours of light per night.

“Right now, the villagers are using kerosene lanterns, which are not only very dangerous, but also very expensive,” Hudson said. “When you think about the fact that these people are making an average of $1 a day, that can eat significantly into the family’s budget.”

Deaton said one of their main challenges was finding components that met their design requirements, allowing the lights to shine bright enough, while not making the system too expensive for the village. The batteries and

the solar panels, specifically, can be very expensive, he said. The system also had to be simple enough so that it could be recreated by other people in the region.

“Ideally, when this is all done, we want to have it where other villages can reproduce it at a low cost,” Dempsey said. “These are very hard working people that deserve to have a few hours of additional light that doesn’t cost an arm and a leg.”

Dempsey said their design, including the solar power components, can be reproduced for about $500.

“Our system is all very scalable and very linear,” Deaton said. “When it does get reproduced, we hope that the village won’t have to learn anything beyond that initial installation. We are creating a manual that provides all of the instructions for the installation.”

Mushroom dyer for economic growth

While Uganda has made great strides toward reducing the level of extreme poverty within the country, economic development remains a significant challenge due to lack of infrastructure and access to larger markets.

The Panache Cooperative in the Wakiso District of Uganda has been successfully growing oyster mushrooms, which are considered a delicacy in Africa. Preserving the mushroom’s shelf life, however, has posed a problem. Without extended preservation, exporting the crop to larger markets is impossible. That is why a WSU Tri-Cities student mechanical engineering team is constructing a mushroom drying device that uses minimal power.

The team, composed of students Sam Sparks, Rachel Estes, Keenan Moll, Ian Pierce, Lorraine Seymour and Joel Larson, was tasked with reinventing traditional commercially available dehydrators. Even the modest-sized versions, Pierce said, require significant electrical power, which is not available in the Wakiso District.

“The biggest challenge we’ve had to deal with is getting a mushroom, which consists of 90 percent water, down to 20 percent while dealing with the Ugandan climate that consists of about 70 percent humidity year-round,” Pierce said.

To combat that issue, the team created a device that utilizes a Lexan polycarbonate top that allows for the air to absorb solar energy and be superheated within the system. The system then uses solar components to promote air flow to help regulate the temperature, which ensures that the mushrooms don’t cook, and in turn, lose nutrients.

The WSU Tri-Cities mechanical engineering team constructs piping for their mushroom dryer that will be implemented this June in Uganda. The team’s goal was to be able to dry approximately 25 kilograms of mushrooms per day with their design.

“The design has to be simple so that they can build it there,” Seymour said. “It all has to be simple parts with simple assembly, which we were able to accomplish.”

Moll said their design should increase the standard shelf life of the mushrooms from 24 hours, which is standard for unrefrigerated fresh mushrooms, to several weeks or more for the dried product. The team’s goal was to be able to dry approximately 25 kilograms of mushrooms per day. The team’s modular design is scalable to accomplish that feat.

“The people in the Wakiso District will be able to use the dryers to dry their mushrooms and sell them as a local product to restaurants and other businesses, which will help them earn a greater living,” Seymour said. “I feel very rewarded to have participated on this project, because we’re creating something that will have a lasting value.”

Saad said the projects provided his students a tremendous opportunity to utilize their skills in engineering to provide solutions to issues across the world.

“These humanitarian projects provided unique opportunities for my students and gave them greater confidence and the skills to work in unfamiliar environments and across cultural differences,” he said.

Beyond implementation

In addition to installing the different devices within their respective communities this June, Hudson said his goal will be to meet with representatives of the Ugandan government, representatives from the universities, as well as other influential figures to see how they can spread their work to other regions and villages.

“These villages are at a zero level for technology,” he said. “Anything we can do to help is a big improvement, and by empowering Ugandans with technology that they can fix, adapt and implement themselves, it will have a lasting impact that will benefit individuals for generations to come.”

Hudson said The Giving Circle has been a tremendous partner. He said he plans to continue the partnership for future student engineering projects.

“The Giving Circle is in it for the long-term and it makes a lot of sense for us to make this an ongoing development project from WSU Tri-Cities,” he said. “This is hopefully just the beginning of a larger effort and partnership.”

A team from Washington State University Tri-Cities placed 17th recently during the SAE Aero Design Competition in Fort Worth, Texas.

WSU Tri-Cities - SAE Aero Design Competition

The WSU Tri-Cities mechanical engineering team poses with the airplane they designed and competed with at the SAE Aero Design Competition.

The team, composed of senior mechanical engineering students Erik Zepeda, Austin Shaw, Ryan Hagins, Matt Kosmos, Arich Fuher and Jose Espinoza, spent five months designing and constructing their airplane. The plane spanned seven feet long and had a wing span of eight feet.

The team said they chose a different design from WSU Tri-Cities teams who competed in years prior, and that their design was also different from many teams competing.

“Most of the other designs were pretty square, but we wanted to go with a more aerodynamic shape,” Shaw said. “We got numerous compliments on the design of our plane.”

During the competition, the team had a very successful first flight, placing fourth in the first round. During their second flight, however, the team had some electrical problems, which they weren’t able to remedy mid-air and the aircraft crashed.

“Even with that crash, we ended up placing 10th in the flight category,” Shaw said. “If we hadn’t crashed, we probably could have placed in the top five teams. That was disappointing, but everything else went really well.”

In addition to their 17th overall placing, the team placed 23rd in regular class design, 22nd in regular class presentation and 18th in regular class most payload transported.SAE Aero Design Competition - Spring 2017

All of the team members said despite their disappointing second flight, they all thoroughly enjoyed the design process, as well as the competition.

“It was a pretty cool experience, especially since it was our senior project,” said Zepeda. “I had never thought about aerospace engineering before, but now I’m thinking about it as a possible career direction.”

All the team members said the project presented them with excellent preparation for their future careers as engineers, regardless of the field of engineering they each go into.

“It definitely gives you good experience for taking on a large engineering project, as well as working with different people, scheduling, meeting deadlines and making presentations in front of judges,” Fuher said.

SAE Aero Design Competition - Spring 2017The design project was part of a senior capstone course taught by Messiha Saad, WSU Tri-Cities clinical assistant professor of mechanical engineering and faculty adviser for the campus’ SAE Aero Design team. Saad said the competition provides the opportunity for his students to learn the mechanics and importance of teamwork, project organization, scheduling, system and product design, product testing, cost analysis and project reporting.

“Through this design project and competition, my students are able to demonstrate and develop their engineering skills set in a real-world environment with real deadlines and stiff competition,” he said. “I am very proud that my students demonstrated the ability to successfully compete with students from some of the top-rated engineering programs in the country.”

PULLMAN, Wash. – As the new associate dean for international programs, Joseph Iannelli will be responsible for developing and expanding global opportunities and collaborations in Washington State University’s Voiland College of Engineering and Architecture.

“Joseph has been providing outstanding leadership in connecting Voiland College faculty and students internationally,” said Don Bender, interim dean of the college. “In keeping with the university’s Drive to 25, we look forward to growing these efforts and broadening our global interactions and experiences.”

Iannelli, who has been at WSU since 2014, will maintain his position as founding director and professor in the School of Engineering & Applied Sciences at WSU Tri-Cities.

In his new role, he said he intends to develop partnerships with overseas universities and organizations in research and student exchange that will enhance economic development and goodwill toward his college, WSU and the state of Washington.

He has led several efforts to increase the university’s global connections. Earlier this year, WSU became the first university in the state to receive European Union funding to support student and faculty research exchanges. He has established partnerships with Technology University of Dresden, Hamburg University of Applied Sciences and Zurich University of Applied Sciences to begin student and faculty exchanges, joint graduate programs and research initiatives.

“These types of collaborations are important because we live in a globalized society,” he said. “When we provide this enhanced education, we graduate students who are ready to excel in their professions on the global scale.”

A fellow of the British Higher Education Academy, Iannelli holds a Ph.D. in engineering science with a focus on aerospace engineering and computational fluid dynamics from the University of Tennessee, Knoxville.

Before the age of 20, Gordan Gavric was already working on technology that continues to change the world of security.

Gavric started as an electrical engineering intern at the Pacific Northwest National Laboratory (PNNL) in the High School Student Research Internship program the summer of his high school junior year working for the Atom Probe group in (define EMSL). Now a junior at Washington State University Tri-Cities, Gavric has transitioned into working in 30784625972_0822818cec_zthe Engineering Development Lab at PNNL, where he works with the creators of the millimeter wave imaging technologies used in body scanners that are deployed in airports across the world.
“It’s been pretty amazing,” Gavric said. “How many other interns get to work on this stuff? I started with PNNL my freshman year and I’ve been with them ever since. I’ve done everything from Python language programming, to circuit development, to building up and testing antennas using some very expensive, very cool pieces of hardware.”

The opportunities he was presented with through PNNL were the primary reason why he chose to attend Washington State University Tri-Cities.

“I think it was probably the best thing I could have done in terms of school and work,” he said. “I was interested in another university because their electrical engineering program was more based in radio and signal processing. But since then, I’ve taken classes here that are more oriented toward digital signal processing. I’ve received one of the best educations because I’m learning from the people that are actually doing it and they do it well.”

30599606060_48bf9994ca_zThrough his current position at PNNL, Gavric is using Python to develop a software application for nuclear security. He developed what is called a graphical user interface, or a GUI, that allows engineers to tweak parameters in real-time to better set instruments to protect a nuclear source. He is also working with millimeter wave antennas that are used in airport and security body scanners.

“Seeing some of crazy concepts behind it and the engineering required to develop that technology and the creativity that was facilitated has been incredible,” he said. “It was not like we were just designing circuits. You got the sense that you could be really creative in the way you solve the big problems in the world with engineering. It has been amazing to see that type of things being done right here in Richland.”

Gavric said his position uniquely allows him to be exposed to engineering concepts and materials first at PNNL, which he then learns about in detail at WSU Tri-Cities.

“Last summer, I was tasked with building a resonant filter and I spent close to two days figuring out everything I could about it at PNNL,” he said. “Then today, in electronics class, we talked about a similar design and learned how to apply it a little differently. I get to first see it applied and then learn more about it. It definitely enriches me because I’m exposed in a real-world experience and then I dive into the details of it in class.”

Gavric said the combination of his WSU Tri-Cities education and his real-world experience at PNNL has poised him with unique experiences that he will continue to use throughout his career in engineering.

“I like that everything correlates really well,” he said. “Everything I learn in class, I see at my job. My teammates at PNNL are like, ‘Have you learned about x? Oh, you learned it last week, OK cool.’ It helps me bond with them.”30268543804_0d4bd8094a_z

Gavric said he has also applied his experience at PNNL and what he is learning in the classroom at WSU Tri-Cities for external projects and leadership opportunities at the university. He and a couple of classmates started the robotics club on campus. He also is the chief justice for the Associated Students of Washington State University where he oversees the student government’s bylaws and judicial procedure.

“One of my favorite things about WSU and PNNL are the opportunities you are presented with,” he said. “WSU Tri-Cities is one of those places where if you have a will to do something, like starting an engineering club, you can. You can make the most out of anything. At PNNL, I’ve been provided with opportunities to advance in my career, like learning new engineering concepts and furthering my skillset.”

Plus, three of the five people on his team at PNNL either taught at or attended WSU Tri-Cities.

“I’m surrounded by fellow alumni,” he said. “It’s been pretty great.”
