Braxton Cuneo, Erich Kramer, Andy Tolvstad, Karen Harper, and Aaron Schraner (left to right) advanced to the world final of the 2017 Rohde & Schwarz Engineering Competition.
Five students in the School of Electrical Engineering and Computer Science will be heading to Germany this summer to compete in the 2017 Rohde & Schwarz Engineering Competition. Their performance in the U.S. preliminary round earned them a spot at the world league competition.
Aaron Schraner, an electrical and computer engineering student, was motivated to compete since he participated last year on a team from the Oregon Institute of Technology that won the 2016 regional competition. Based on his experience there, he recruited Karen Harper for additional electrical engineering knowledge. All the other team members are in computer science: Braxton Cuneo, Erich Kramer, and Andy Tolvstad.
Their task was to make improvements to software for a digital-signal processing application that could ultimately make video streaming better. Specifically, they were asked to speed up the processing of the software-based DVB-T2-Coder, based on the open source GNU Radio project, while maintaining accuracy.
“Signal processing is traditionally very, very computationally intensive, so any optimizations you can get out of something like that are going to be very beneficial to your workflow,” Andrew Tolvstad said.
“There was one loop we optimized that was run about 1.2 million times,” Karen Harper agreed.
“Just by changing a data type that was 32-bits wide to one that was 64-bits wide, we took another 5 to 10 percent off the total amount of time it took to run the program,” Aaron Schraner said.
During the competition, students made improvements to the code that was then automatically compiled and tested for performance once they submitted it via Git. Rohde & Schwarz continuously published a leader board of the top performing teams so the teams could watch their ranking move up or down.
The team members are excited to have an all-expenses paid trip to Germany, and are squeezing the trip into very busy lives of classes and internships. They also have a chance to win $3,000 for the top prize, $1,500 for second place, and $750 for third place.
But the money was not the only objective.
“It’s been a lot of fun,” Tolvstad said. “Just the thrill of trying to take something and make it the best it can possibly be by just rearranging its parts.”
This final will be held in Munich, Germany at the Rohde & Schwarz headquarters. Rohde & Schwarz is a privately held company with over 10,000 employees worldwide, including a design center in Beaverton.

“Gadgets and Gizmos” was the theme for the first HWeekend of 2017 on January 20-22, jointly sponsored by the College of Business and the College of Engineering.
In just one weekend, forty-seven students from business and engineering designed, built, and pitched their idea for a marketable product including temperature based alarm clock, a computer controlled potato launcher, a 3-D printed longboard fender, and a self-playing guitar.
It was the seventh iteration of the popular event that provides students from different disciplines an opportunity to work together in teams. Students came from a variety majors including business, bioengineering, civil engineering, chemical engineering, computer science, electrical and computer engineering, environmental engineering, and mechanical engineering.
“This event is really cool, because I get to do things that I normally don’t get to do in my major,” said Alec Westbrook, a chemical engineering student who worked on the 3D printed longboard fender project. “I mean, how often can a guy that is mixing chemicals all day work with his hands and create something new?”

This event allowed students to make use of the new Buxton Hall Makerspace and Mastery Challenge lounge, which gave students access to 3-D printing, soldering irons, a drill press, laser cutting, and UV ink logo printing.
Mentors for this HWeekend included six industry members from Intel and two from Microsemi.
“People here are really excited about the things they are making,” said Aayush Pathak, a silicon architecture engineer from Intel who attended HWeekend as a mentor. “And to be a part of it and share what I have seen in my school and life — it’s a proud feeling.”
Staff from both the College of Business and the College of Engineering also helped mentor students through the creation and marketing of their projects.
“It’s an incredibly valuable partnership between business and engineering,” said Dale McCauley, the makerspace manager for the College of Business. “The students are getting the chance to build relationships that ordinarily wouldn’t form. If you get business students to understand how engineers think and vice versa, I think that is valuable.”
At the end of the weekend, the students received group awards for their dedication and hard work. The Executors award goes to the team that produces the best engineering execution of their idea to create the most polished final product, the Helping Hand is for the team that contributes the most to other teams, and the InnovationX Pitch awards go to two teams who had the best business pitches for selling their prototypes.

Graduate student Ziad Eldebri was the winner of the Lattice Hackathon Contest hosted by Lattice Semiconductor. He was awarded the grand prize of $5,000 and a trip to the Consumer Electronics Show 2017 in Las Vegas, Nevada. Eldebri competed against other students across the country to create an original idea on how to improve a battery powered device using Lattice FPGA. Eldebri’s winning idea was to develop a LIPO battery charger that could be used in any product that uses Lattice FPGAs.
“It was awesome, because I got to attend the Consumer Electronics Show and see state of the art electronics that ranged from 3D printed cars to drones that will talk to you,” Eldebri said. “I also got to learn more about Lattice Products and FPGAs.”
The goal of the competition was to create new ideas on how we can use FPGAs to improve our lives and the electronic devices that we use every day.

Guest post by Helena Bales
I had an amazing experience this summer at the University of Georgia working in the Small Satellite Research Lab. The lab was founded by undergraduate students, myself included, partnering with professors, NASA, and the U.S. Air Force. Space seems impossibly far away and hard to get to, but with the increased popularity and strength of the small satellite community, it is now easier than ever to reach, even for self-funded, undergraduate engineering students.
We started as a small group of students and created a crowdfunding campaign with the goal of launching a small satellite into orbit. Most of the students on the project were at the University of Georgia (UGA). We had reached out to faculty members in the UGA geography department to see if they wanted a science payload to fly on our CubeSat. CubeSats are small satellites of a specific size. For example, a “1U” CubeSat is 10 cm wide, 10 cm deep, and 11 cm tall. The standard size has aided the commercialization of space.
The mission patch for the Small Satellite that will perform multi-spectral analyses of the Georgia coast.
Currently, we have two CubeSat projects and about 20 members. The CubeSats launch off the International Space Station. One will look at Earth in order to track sediment plumes, algal blooms, and chemical runoff around Georgia. The other will create 3D maps of large geographic features such as mountains. We couldn’t have dreamed that this project would end up where it is now — a lab run by undergraduate students with two fully funded satellite projects.
My role in the lab is to develop the algorithms that we need to accomplish our mission objectives. That mostly involves adapting existing algorithms for use on orbit. Running software on orbit has different limitations than on the ground, so the software needs to be adjusted accordingly. For example, when dealing with space, engineers must take account of power shortages, overheating, and time limitations that might compromise transmission of data. Fortunately, we know these constraints ahead of time. With careful planning and testing, we can insure that our code will run on orbit.
The process of developing cube satellites posed both unique opportunities and struggles. As undergrads, trying to figure out how to build two satellites, we are all learning together. And the experience of working at the Small Satellite Research Lab is incomparable to most undergraduate experiences, because of the nature of the project and the close relationships developed through solving problems in space. Balancing the demands of the project takes a close-knit group of scientists and engineers and communication between group members. Through the experience we have built a productive lab and became close friends.

Eight of our members (myself included) received scholarships to attend the Small Satellite Conference in Logan, Utah. At that conference we had the opportunity to attend six days of talks about every aspect of small satellite missions. We all learned more than we could have imagined. We were also able to network with industry professionals from organizations like NASA and SpaceX. That week opened our eyes to issues that we hadn’t thought about yet, and introduced us to new satellite hardware vendors. When we returned from the conference, we were equipped to onboard new lab members, finalize our payloads, design our ground station, and plan outreach events.
Despite ongoing encouragement and success, we continue to struggle with getting the funding that we need to make a lab that can support multiple space missions. For example, using space-grade hardware requires a cleanroom in order to assemble our satellite to meet the standards set by NASA and the U.S. Air Force, who have each funded our missions. The funding we’ve received for the projects assumes that there is already a lab that is outfitted with all the supplies necessary to build and test a CubeSat, so we face the additional hurdle of establishing our lab.
I’m proud to be part of a group that welcomes challenges instead taking the easy route — an important characteristic for the next generation of scientists and engineers solving problem in the limitless reaches of space. With creativity and persistence, the University of Georgia Small Satellite Research Lab is pushing itself and reaching new heights.

Lizbeth Marquez and Nick Malos, advisors for the School of Electrical Engineering and Computer Science pose with Benny the Beaver.
In their role as advisors, Lizbeth Marquez and Nick Malos help hundreds of students in the School of Electrical Engineering and Computer Science navigate their way through college. Their goal is to help students succeed and ultimately earn their Oregon State degrees. According to a recent report from the Commission on the Future of Undergraduate Education, only 60 percent of college freshmen get a bachelor’s degree within six years. While there are many reasons students don’t complete their degrees, Lizbeth and Nick have some advice to offer to help you succeed.
Lizbeth’s Advice
Get Organized College can be different from high school in that high school teachers tend to lead you through all the homework and due dates. In college, the professors post the assignments — often for the entire semester — and expect you to be prepared. Get a planner, use a smart phone app, or get a wall calendar — whatever it takes for you to know when assignments are due.
Find the right place to study It may be your dorm room or a cozy corner of the library, but find a place that works best for you to get your work done — while avoiding as many distractions as possible. There are many places to go such as the MU, the Valley Library, your residence hall, or most buildings on campus!
Seek a balance College life can be chaotic with various academic and social events. Make sure you stay balanced and don’t overload yourself. One way you can do this is by visiting OSU’s Mind Spa.
Get involved You may feel overwhelmed with being homesick or feeling like you don’t belong. We encourage you to consider joining a student group (and be careful not to go overboard), whether it’s academic, religious, athletic, cultural, or social. You’ll make new friends, learn new skills, and feel more connected to OSU.
Take advantage of the academic resources Most schools and colleges offer study tables or have tutors available. If you’re having difficulty, these resources are another tool available to you. Another idea: Talk to your classmates about getting a group together to study.
Nick’s Advice
Explore your major and career options It is important to remember there is no one “right” or “best” major. You should select a major that aligns with your skills, interests, and goals. Talking with a career counselor in the Career Development Center can help you explore the options. Don’t be afraid to change your major. It is estimated that about 80% of undergraduate students across the United States change their major at least once (National Center for Education Statistics, n.d.).
Get to know your fellow students It can feel intimidating at first, but it is important to get to know your fellow students because they can be a great resource. What better way to find others who share your same interests?
Get to know your professors Talk to your professors and attend their office hours. I promise they are not as scary as you might think. Professors are here to help you learn the material, challenge you to think outside the box, and further your understanding of the subject. They are also a great resource when you need letters of recommendation for scholarships, internships, or graduate school. Just remember, the better they know you, the easier it is for them to write a quality letter.
Put in the time & effort Some of the easiest ways to succeed include:
Meet with your advisor It is important to speak with your advisor early and often. They are the ones who will provide you with your registration pin number. But more than that, they can assist with course selection and planning; registration; understanding major and degree requirements; and navigating the processes to find extracurricular opportunities, internships, jobs, and more.
Jen-Hsun Huang, co-founder, president and chief executive officer of NVIDIA, is honored this week by the Oregon State University Alumni Association at the 35th Annual Spring Awards. Huang is receiving the E.B. Lemon Distinguished Alumni Award for his significant contributions and accomplishments within the society and the university.
Since graduating in 1984, Huang has kept close ties with Oregon State as he has progressed through his career. He came to Oregon State when he was 16 to start his degree in electrical engineering. One of the best things that came out of his experience here, he said, was meeting his wife, Lori Mills. The two were assigned to be lab partners in an electrical engineering fundamentals class, and they married five years later. Together they are benefactors of the Kelley Engineering Center, contributing $2.5 million.
Huang, who was also a nationally ranked junior table tennis champion in high school in Beaverton, spoke to Oregon State students about how to succeed on a visit to campus in 2013.
“The most important thing is to do important work — to do relevant work. Then you have to do it with the best of your might,” he said. “If you do that…you’ll be surrounded by the world’s best at what they do, and then almost anything is possible.”
The success of NVIDIA was built on innovations for graphics processing units for computer gaming. The reach of NVIDIA is beyond video games, however, now entering the realm of artificial-intelligence projects such as self-driving cars. This month NVIDIA announced a new chip that is specifically designed for a technique called deep learning.
The Spring Awards Celebration will be held Friday, April 22, 2016 in the CH2M HILL Alumni Center, on the OSU campus in Corvallis. Registration is requested by April 20.
Carl Beery shows the project that earned him four achievements in the Mastery Challenge.
Carl Beery, a junior in electrical and computer engineering, took first place and a cash prize of $150 in the Mastery Challenge for winter term.
The Mastery Challenge is a new extracurricular program hosted by the School of Electrical Engineering and Computer Science at Oregon State University to provide more hands-on learning opportunities for all students, regardless of major. The program is based on a concept called gamification which uses elements of game playing, such as leader boards and badges, to motivate participants to gain new abilities such as 3D modeling and Python programming.
Beery had already been working on projects on his own, but he realized the Mastery Challenge would give him a better framework for learning new abilities and more motivation for completing tasks.
“The Mastery Challenge is a good starting point to learn about topics you wouldn’t have thought about trying on your own,” Beery says. “Without it, I wouldn’t have learned how to laser cut, and laser cutting is pretty cool.”
To participate, students login to the Mastery Challenge website with their university account to see the list of challenges for which they can earn achievements. In winter term two cash prizes were awarded — one for the highest number of achievements, and a second was awarded randomly to anyone earning at least one achievement.
Beery had completed eight achievements and was tied for first place when he realized a project he had been working on for class — an audio amplifier — would qualify him for four more achievements. He simply videotaped his class presentation and uploaded it to the Mastery Challenge website as proof of completion.
“The experience Carl had was what I was hoping for — a fun way to gain new skills that will benefit him in the future as he enters the job market,” says Don Heer, creator of the Mastery Challenge program and instructor of electrical and computer engineering in the College of Engineering.
The School of Electrical Engineering and Computer Science at Oregon State University is initiating a new extracurricular program to provide more hands-on learning opportunities for students. The Mastery Challenge program is based on a concept called gamification which uses elements of game playing, such as leader boards and badges, to motivate participants to gain new abilities such as 3D modeling and Python programming.
“The program is designed to help students apply the knowledge they learn in classes to practical skills that they will need for jobs when they graduate,” said Don Heer, instructor of electrical and computer engineering. Experiential learning is a focus for Heer who has also created the TekBots program, which integrates course content with building a robot; and the CreateIT Collaboratory, an internship program for students to work with outside clients to create prototypes.
To participate, students login to the Mastery Challenge website with their university account to see the list of challenges for which they can earn achievements. Participants can work on their own, or get help by contacting students who already have that achievement. Prizes will be awarded to students with the highest number of achievements each term. Helping other participants is another way for students to earn achievements.
Peers also participate in the evaluation process. To earn an achievement, a participant must demonstrate their ability by uploading a video or document to the website for review. Students who already have that achievement can recommend to Heer if the application should be accepted or denied. Heer then makes the final decision.
The Mastery Challenge program is open to anyone at Oregon State — students from other majors, faculty and staff can participate. Initially the program will include abilities in electrical engineering and computer science, but Heer’s vision is that the program will expand across the university, so students can earn achievements in a wide variety of disciplines.
Questions about the program can be directed to Don Heer.
Terri Fiez, professor of electrical and computer engineering at Oregon State University, was selected as the 2016 winner of the IEEE Undergraduate Teaching Award “for innovative undergraduate engineering and computing curriculum development fostering student engagement and retention.” IEEE is the world’s largest professional technical association, and honors one individual each year for inspirational undergraduate teaching.
Innovative teaching has long been a focus for Fiez who created the TekBots Platform for Learning and spearheaded the nation’s first online post-baccalaureate program in computer science. She received the 2006 IEEE Educational Activities Board Innovative Education Award, the 2006 OSU Student Learning and Success Teamwork Award, the 2014 OSU Vice Provost Award for Excellence: Innovation in Online Credit-based Teaching, and she was recognized by the students of the School of EECS at OSU as the OSU EECS Professor of the Year in 2014.
Fiez and collaborators designed the TekBots Platform for Learning to bring experiential learning into the electrical and computer engineering curriculum. Students apply their classroom knowledge to create their own robot, and as they progress through the program they add more functions to their TekBot. The program has been widely adopted at other national and international educational institutions, resulting in more than 10,000 student experiences with TekBots to date.
To serve the growing needs in industry for trained computer scientists, Fiez led the development of a bachelor’s degree program for post-baccalaureate students that could be delivered online. In June 2012, the program was launched by Oregon State’s Ecampus program. Today the program boasts over 1,000 students from all over the country and the world with backgrounds as diverse as journalism, anthropology, chemistry, music, and law. It has been cited as one of the top online computer science programs in the country by multiple sources including Best College Reviews.
Karti Mayaram, professor of electrical and computer engineering, said, “Professor Terri Fiez has been a pioneer with a unique vision for engineering education that prepares ECE and CS undergraduate students for leadership positions in academia and industry.”
After 16 years at Oregon State, Fiez will assume the role of vice chancellor for research at University of Colorado Boulder in September of 2015.
The 2015 Oregon State AIAA team at the Intercollegiate Rocketry Engineering Competition held in Green River, Utah.
For the second year in a row, the Oregon State University’s branch of AIAA (American Institute of Aeronautics and Astronautics) took first place in the payload competition at the Intercollegiate Rocketry Engineering Competition held in Green River, Utah. The team also placed third in the overall competition in the advanced category that targets an altitude of 25,000 feet — their launch reached 17,611 feet and a maximum speed of Mach 1.4.
The competition, hosted by the Experimental Sounding Rocketry Association (ESRA), had 41 rockets launched this year by 36 different colleges representing seven countries (Australia, Brazil, Canada, Egypt, India, Turkey and the U.S.).
Oregon State’s team stood out in the competition for building nearly all of the components themselves. In fact, computer science student, Soo-Hyun Yoo said he had a hard time getting the judges to notice the extra work the team put in.
“All of the other teams at the competition had an aerospace program and bought off-the-shelf components. There were a very limited number of teams who built their own software and electronics and so very few people were asking about those things. I had to try really hard to make sure they realized the significance of having our own system that we can build on and modify to fit various needs,” he said.
Yoo said that a few of the payload judges were very excited about their original components and it was what likely earned them the payload award again this year. The award is prestigious because it includes all the teams in the competition from both the basic and advanced categories, and comes with a $700 prize. Since the award has been offered just two times, Oregon State is the only team to win it.
Going, going, gone. Oregon State took first place in the payload competition and placed third in the overall competition for the advanced category at the Intercollegiate Rocketry Engineering Competition.
The payload is the main purpose of sounding rockets, which are designed to conduct scientific experiments. The Oregon State team built a deployable payload in the nose cone of the rocket that deploys at the highest altitude and uses propellers to accelerate downward to counteract aerodynamic drag force and achieve microgravity in order to conduct experiments in a zero gravity environment.
The OSU team toggles the external power buttons to physically arm the electronics in the rocket. The ‘live’ circuits are connected to black powder ignition charges, hence the protective face masks.The ground station engineers attempt to make a radio connection with the transmitters in the rocket from 750 feet away. The receivers needed to be elevated in order to make the connection.
This year’s team built significantly on the success of last year’s rocket which won the basic category (targeting 10,000 feet) in 2014 at their first competition. Four sub-teams contributed to this year’s rocket: a payload team, a structures team, a propulsion team, and an aerodynamics and recovery team. At Oregon State’s 2015 Engineering Expo the payload team won the industry award for electrical and computer engineering and earned honorable mention recognition for the Boeing Engineering Excellence Award.
Elliott Fudim, an electrical and computer engineering student who joined the club as a senior, hopes that other students will discover the club sooner than he did and have more years to advance the rocket.
“It’s a once-in-a-lifetime opportunity. It’s one of the coolest things I’ve ever been a part of. And it’s important to keep on setting the bar higher,” Fudim said.
Yoo agreed, “I don’t think many students at OSU can say they made something that broke the speed of sound. It’s pretty cool stuff.”
Both Fudim and Yoo said that aside from the cool factor of being able to build a rocket, the experience of working on a cross-disciplinary team was more realistic to what they will experience working in industry. Additionally, working on a rocket that deals with extreme conditions such as speed and temperature offered interesting challenges.
“The limited test cycle in which we only get a few chances to launch and the cost of failure is high, was a learning experience. Getting it right the first time was stressful but also exhilarating,” Yoo said.
The team performed on-ground tests of the various systems and also practiced their launch setup to make sure everything went smoothly on competition day (view photos). Their only full-flight test was performed in Brothers, Oregon near Bend where they could secure a waiver from the FAA for air space.
For future competitions, the club has begun developing an experimental hybrid rocket motor. The current rocket is a solid propellant rocket with a simple ignition – “you light it and it just goes,” explained Yoo. The hybrid rocket will have a throttle to adjust the thrust depending on need.
This year’s team was able to compete with the support of their sponsors: Advanced Circuits, CadSoft EAGLE, and the College of Engineering at Oregon State. “We couldn’t have done this without them,” Fudim said.
