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.

Margaret BurnettProfessor Margaret Burnett has been on a roll lately, to put it mildly. Her most recent award is the 2017 Undergraduate Research Faculty Mentoring Award announced this month by the Education Committee of the Computing Research Association. This follows a string of awards from national organizations including the CHI Academy, the National Center for Women and Technology, ACM SIGSOFT, and IEEE Symposium on Visual Languages and Human-Centric Computing. She was also named 2016 Distinguished Professor recipient by Oregon State University, the highest academic honor the university can bestow on a faculty member.

The following quote comes from the the Education Committee of the Computing Research Association award announcement:

Margaret Burnett, Ph.D., is a distinguished professor in the School of Electrical and Computer Engineering at Oregon State University (OSU), a member of the ACM CHI Academy, and an ACM Distinguished Scientist. Burnett has contributed pioneering research on how ordinary users interact with software and optimizing that interaction. This resulted, in part, in the development of a new subarea, which is at the intersection of human-computer interaction and software engineering, called end-user software engineering.

 

Throughout her academic career, Burnett has continuously worked with undergraduate researchers and even accommodated high school students in her lab. She has mentored 39 undergraduate students in research; 21 were from underrepresented groups in computing, 32 co-authored published research papers, and 25 went on to graduate studies. A selection of the honors of her highly accomplished mentees includes three Google Scholarships, three NSF Graduate Fellowships, and two National Physical Sciences Consortium Graduate Fellowships. In her nomination, several mentees attested to her personal influence on and involvement in their lives and careers.

 

Impressively, Burnett influenced the culture of faculty undergraduate research mentoring in her school, increasing it to 50% participation. She has also led efforts to better support a diverse undergraduate population through trips to the Grace Hopper Celebration of Women in Computing, the adoption of a diversity plan, and new experimental scholarships for incoming freshmen women in computing. She has received awards from NCWIT, Microsoft, and OSU for her mentoring and research.

Ziad EldebriGraduate 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.

Bret Lorimore, Chris Vlessis and George Harder won the Best Use of Outside Data at DataFest, a nationwide event.

Computer science students Bret Lorimore, Chris Vlessis and George Harder took a big plunge into big data when they participated in DataFest, a nationwide hackathon-style event, in April.

The group won the Best Use of Outside Data award in the American Statistical Association competition hosted at over 20 universities, including Oregon State University. DataFest is a competition that challenges students to analyze a complex data set over a single weekend.

“We had nine teams with a total of 38 students from Oregon State, University of Oregon and Reed College, representing statistics, computer science, neuroscience, biophysics and biochemistry, business, math, and economics,” said Charlotte Wickham, an assistant professor of statistics at Oregon State and organizer of the event.

Competitors didn’t have any access to the data ahead of time, nor did they know where the data would come from. This year, Ticketmaster provided data that included information about the company’s Google analytics, ad words, website user “click” data and ticket sales.

Though participants were given millions of data points, the tasks they were given to accomplish were not highly defined. Students needed to decide for themselves what research question they wanted to answer and then worked to extract valuable information out of the data.

“They wanted people to come up with information that Ticketmaster could use as an actionable item to improve their business,” said team member, Lorimore.

Ultimately, the team chose to tackle the effectiveness of Ticketmaster’s advertisements.

“We found Ticketmaster was wasting a lot of money on Google keywords,” Vlessis said.

The trio discovered that people were clicking on the ads but not following through to purchase tickets and as a result, the company lost more than $1.4 million over the course of a year on ineffective advertising.

Vlessis’s startup company, SteadyBudget, happens to solve the same types of problems presented at this year’s DataFest, so the team had access to additional data from advertising analysts.

They looked at general trends of how SteadyBudget analysts interact with their advertisements and the decisions they make about placing or pulling ads. The group then used that information to help make advertising decisions for Ticketmaster.

“It was a way to automate the task of identifying poor-performing keywords and good-performing keywords and make the decision to stop paying for the ones that aren’t working and continue paying for the ones that are,” Harder said. “So we would save them money and automate the process at the same time.”

Although DataFest was about solving a data problem, it was not all about the numbers. “We spent a lot more time brainstorming and talking about what we wanted to do than sitting down and writing code,” Harder said.

“When you get that much data, it’s hard to make any sense of it,” Lorimore said. “Identifying the questions to ask is a challenge in and of itself.”

The group also gained an appreciation for the different ways people approached the data. “Seeing some of the techniques others used, and the way they went about approaching the problems and finding solutions, was stuff I never would have thought of,” Vlessis said.

Jen-Hsun Huang photoJen-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.

Mike Rosulek

Mike Rosulek, assistant professor of computer science, was selected for a Google Research Award for a grant to advance methods of customer privacy. The award will allow Rosulek to hire a graduate student to work on the project, and give them the opportunity to collaborate with Google researchers and engineers.

“I have lots of ideas in this space, and it will allow me and a student to dive in head first exploring them,” Rosulek says.

Companies are looking for inexpensive ways to share information with each other without violating the privacy of their customers. For example, two companies may want to find out which customers they have in common. A tool from cryptology called private set intersection allows two parties to find items in common on two separate lists without revealing anything else from those lists.

One part of Rosulek’s research seeks to strengthen the security of private set intersection tools while keeping the costs reasonable so that companies are more likely to adopt good practices for keeping their customer’s information secure.

Another part of the project will work on flexible (or “fuzzy”) matching of items on lists such as addresses. Names and street addresses may have differences in spelling, so looking for exact matches between two sets can be too restrictive. Rosulek’s research will seek to modify current techniques to allow for “close enough” matches.

“I’m excited to see that Google is interested in these advanced cryptographic tools. I’m excited that the techniques can be used to protect sensitive user information. And I’m excited about the new technical and mathematical challenges on the roadmap,” Rosulek says.

Margaret BurnettMargaret Burnett, a professor of computer science at Oregon State University, is one of eight researchers worldwide to be inducted into the CHI Academy in 2016 for pioneering contributions to the field of human-computer interaction. It is one of the highest awards given by the Association for Computing Machinery, SIGCHI.

When Burnett began her career in 1971, there were few female computer scientists, indeed, she was the first woman software developer hired at Procter & Gamble Ivorydale. A few degrees and start-ups later, she joined academia with a research focus on people who are engaged in some form of software development. She was the principal architect of the Forms/3 visual programming language, and pioneered the use of information foraging theory in the domain of software debugging.

Burnett co-founded the area of end-user software engineering, which aims to improve software for computer users that are not trained in programming. She established the EUSES Consortium, a multi-university collaboration which through her leadership has garnered international recognition.

Her current research investigates “gender-neutral” software, uncovering gender inclusiveness issues in software from spreadsheets to programming environments. She has published more than 200 papers, with several receiving best paper awards and honorable mentions, and has presented invited talks and keynotes on her research in 14 countries.

Burnett is also an award winning mentor, and recently received the Undergraduate Research Mentoring Award from the National Center for Women and Information Technology.

dEATS team: Vahid Ghadakchi (computer science), Elijah Mcgowen (finance), Josh Cosio (marketing), and Dylan Gould (entrepreneurship).

Computer science graduate student, Vahid Ghadakchi, decided to step out of his normal life one weekend this fall and try something new. So, he put aside his Ph.D. thesis work and attended the Willamette Startup Weekend at Oregon State University — a 50 hour event to inspire entrepreneurship.

Not only did his team win the second place prize for their app, but they are continuing to develop it into a business.

At the event, Vahid was quickly snapped up by business students Dylan Gould (entrepreneurship), Josh Cosio (marketing) and Elijah Mcgowen (finance) for their team. The three came to the event together with an idea for an app that restaurants could use to help bring in business during slow times. Vahid filled the team’s need for a computer scientist to implement their idea.

Initially the team just wanted to have some fun and learn some skills, but once they started market testing the app with businesses and potential users they realized their product could go farther than a weekend contest. Nearly all of the businesses they talked to said they would use the app, and one expressed interest being a beta tester.  Customer responses were very positive as well.

Restaurants could use the app, called dEATS, to post discount deals that would last for a limited amount of time, such as 30 minutes. The app would have a count-down timer so customers would know how long the deal would be active. The product would help businesses drive customers to their restaurants during slow times, and customers could get ideas for where to go by checking the app for deals.

The team is planning to apply to the OSU’s Advantage Accelerator to help develop their idea into a business, and is looking for more engineers to join the team to make the business a reality.

Vahid said that the experience was a great break from working on his thesis and he also learned some valuable skills that go beyond what can be learned in the classroom.

“I realized how important it is for a computer science student to learn to communicate with people in business and other areas, because they have a different perspective that can help you develop a better product,” Vahid said.

Phylicia Cicilio

Phylicia Cicilio’s project to help a rural Alaskan community improve the reliability and cost of their electric power microgrid will be funded by the Evans Family Graduate Fellowship in Humanitarian Engineering at Oregon State University. The fellowship will pay for her travel next summer to Alaska to meet with the community and work out the details of the project.

“I’m really excited to travel there and work with the people. I’m from rural Vermont, so I love rural communities,” said Cicilio, a graduate student in electrical and computer engineering, advised by Professor Eduardo Cotilla-Sanchez.

Cicilio’s move to Oregon State this fall marked a switch in her career. Her undergraduate degree is in chemical engineering, but after a year of working in the field she realized that electrical engineering would allow her to better pursue her broad interests in renewable energy.

The project in Alaska will allow her to integrate her focus on renewables with her other interests in energy storage and microgrids, and her desire to help rural communities. Although she has not yet settled on which community she will be helping, there are several options where she can make an impact.

“People in rural Alaska pay 15 times more than everyone else in the U.S., so one goal could be to see how inexpensively we can produce electricity,” she said. “They also live a subsistence lifestyle and don’t deal with money, so paying for utilities can be a problem. Having a system that can be run by the people would be a huge benefit.”
