Research Universities Can Take a Key Role in Achieving Sustainability

December 6, 2007

Research universities are singularly well-positioned to play a significant role in affecting the long-term development of a sustainable society, according to Jean-Lou Chameau, president of the California Institute of Technology (Caltech), speaking Dec. 5 as part of the Distinguished Lecturer Series of the Bourns College of Engineering at the University of California, Riverside. He is pictured (l. to r.) with Dean Reza Abbaschian and Peter Gevorkian, who presented the first Distinguished Lecture in the series on Nov. 7, 2007.

In an address titled "Why Sustainable Campuses Matter," Chameau, an engineer whose technical interests include sustainable technology and environmental geotechnology, spoke about the uneven record of society in recognizing environmental threats and taking action to balance economic development and a healthy environment.

Because of its size, resources and mission, the research university, like Caltech and UC Riverside can be a practical green urban laboratory that will pioneer sustainable living.

“You’ve probably realized that sustainability is a broad, complex topic with scientific, technological, political, economic and social dimensions,” Chameau said. Universities exist to produce students who are problem-solvers and critical thinkers, who are adept at science and technology, who are aware of current issues and cultural values, and who work well in interdisciplinary teams, he added.

If students care about a sustainable society, they will be fundamentally well-suited to meet the challenge, Chameau predicted.

“I believe we should get students, faculty and staff involved in studying the physical environment of the campus, that they should explore long-term technological options for our buildings, energy production, landscaping and even food service,” Chameau said. “Our students, faculty and staff … should be plugged into the decision making processes—the product of their work should be used to make us the most resource-effective, sustainable campus we can be.

“And along the way, we will learn,” he continued. “We will learn not only about the topic of sustainability, but more importantly, we will learn how to make it happen. And we’ll help others in the community become more sustainable, too.”

He shared a few examples of ways sustainability can become part of campus life:
* new construction standards can significantly reduce the operating costs and the environmental impact of campus buildings;
* environmentally sustainable landscaping standards;
* cogeneration technologies that reduce emissions while providing the campus’ complete energy needs;
* solar collectors placed on the roofs of large buildings such as parking garages; and,
* policies discouraging the use of automobiles, or encouraging the use of bicycles by undergraduates.

It is the job of a university to use its precious resources for teaching and discovery, Chameau argued. The more an institution can replace expensive, unsustainable infrastructure with sustainable campus practices, the better it will be doing that job, he said.

“I’ve always viewed university campuses as excellent test-beds for green city ideas,” he said. “Caltech, like most universities, has a youthful, energetic, and creative community and our scale allows us to experiment—something we do well at Caltech.

“It seems a bit unfair, doesn’t it, to pin the hopes of civilization on a generation that did little to create the problem,” Chameau said. “That is why I feel strongly that we have an obligation to bring sustainability, and the effects of climate change, into the college experience.

“And we can avoid the lesson of hypocrisy by integrating sustainability into the way we manage our campus,” said Chameau.

Chameau’s address was the second in the college’s Distinguished Lecturer Series. The first in the series was Peter Gevorkian, a nationally-known authority on solar energy and other renewable energy systems, who presented "Renewable Energy Systems Industry Growth and Its Impact on the U.S. Economy, Business, and Professional Career Opportunities." Additional events in the Distinguished Lecturer Series are being planned for 2008.

Wu and Tan win Best Paper Award

November 5, 2007

Ph.D. student Wei Wu and Prof. Sheldon Tan (at right and left in photo) have received a Best Paper Award from 25th International Conference on Computer Design (ICCD’07), held Oct. 7-10 in Lake Tahoe, CA. This is a primary conference for VLSI/CAD and computer architecture. Only about 2 percent of papers submitted win the Best Paper Award from ICCD annually. The prestigious award indicates the high-quality research results from Wei Wu, a Ph.D. student of Prof. Tan.

The paper is about improving the reliability of an important component in today’s microprocessors, the on-chip cache, which temporarily holds the data and instructions in a microprocessor. The paper shows, for the first time, that the uncertainty (or parameter variations) in the VLSI manufacture process can significantly impact the lifetime of a microprocessor due to the induced temperature changes. Based on their analysis, the paper proposes a new scheme to reduce the peak temperature of the on-chip cache, which leads to smaller power consumption and reduced peak temperature, resulting in the improved lifetime (reliability) of the cache. The award-winning paper was co-authored by J. Yang at University of Pittsburgh, and S.-L. Lu, who is with Intel Corporation.

Venkatram to lead air quality impact study

October 9, 2007

Mechanical Engineering Professors Akula Venkatram and Marko Princevac have been awarded a grant from the California Institute for Energy and Environment to assess the air quality impact of distributed generation of electricity in California. Dr. Venkatram (Principal Investigator) and Dr. Princevac (Co-principal Investigator) will study the air quality impact of the distributed generation (DG) of electricity, in which large central generating plants are replaced with small generators placed in urban neighborhoods. This approach will save on the costs of transmitting energy from central plants, and allow neighborhoods to be independent of the economics of plants owned by large companies. Although these DG plants will run on clean fuels such as natural gas, they can have an impact in their immediate neighborhoods because they release their emissions relatively close to the ground. Field studies, water channel experiments, and modeling will be used to study this impact. Drs. Venkatram (right) and Princevac (left) are pictured in front of the water channel facility they will use for environmental flow modeling.

Undergrads offered year-round research and mentoring

September 26, 2007

A multi-disciplinary project that encourages undergraduates to complete bachelor’s degrees and go on to obtain doctorates in biological sciences and engineering has won a grant from the National Science Foundation (NSF). A team led by Principal Investigator Sharon Walker, a Chemical & Environmental Engineering professor, Bioengineering professors Victor Rodgers and Valentine Vullev and nine other UCR faculty will provide research experiences and mentoring for undergraduate students from UCR and Riverside Community College (RCC).

The grant, known as MY BEST@ UCR (Mentoring Year-round in Biological Engineering, Science and Technology) will fund six students a year for the next five years. The year-round aspect is a departure for NSF, which usually funds summer Research for Undergraduate (REU) programs. Dr. Walker, who holds the John Babbage Chair in Environmental Engineering, is excited about this opportunity for engineering and science majors to continue their investigations for a full year. Areas of study include biosensor development, bacterial adhesion, microfluidics, transport phenomena, cell signaling and cell electromechanics. Although the team hopes that students underrepresented in science and engineering will be attracted to the program, all students are eligible to apply.

Recruitment will begin in the spring, drawing from both the UCR and RCC student bodies. Last summer Dr. Walker established a relationship between the two schools with a USDA-funded project in water quality research designed to motivate students to transfer from a two-year to a four-year institution. Building upon this existing program, the new NSF effort will provide students intense training over the summer, followed by research assistantships throughout the academic year on a part-time basis that accommodates their other studies. Participants will present their findings at an annual UCR symposium and at the Southern California Conference on Undergraduate Research.

Air Force funds team’s research on nanostructure-based solar cells

September 17, 2007

Electrical Engineering Professor Alexander Balandin (pictured) has teamed up with industry and several other universities for research aimed at increasing the efficiency of solar cells based on nanostructured materials. The $1.3 million project, funded by the US Air Force Office of Scientific Research (AFOSR) involves engineers from CFDR Corporation in Huntsville, Alabama, and researchers from UC Riverside, University at Buffalo and Rochester Institute of Technology. The research to be carried out in Dr. Balandin’s Nano-Device Laboratory (NDL) focuses on the design and optimization of intermediate-band (IB) solar cells, which have been predicted to have an enhanced photovoltaic efficiency (how efficient a device is in converting solar light to energy). The power conversion efficiency of conventional semiconductor solar cells is limited to about 30 percent, which prevents their wide application for commercial power generation. Nanotechnology, utilized for implementing the IB solar cells, has the potential to deliver a substantially higher photovoltaic efficiency. Theoretical models, which are under development in Balandin’s group, will be used for the physical-based modeling and design of the semiconductor solar cells. One of the project’s goals is the creation of commercially available software tools for accurate simulation of the performance of solar cells.

Engineer and biologist team on morphological image database project

September 5, 2007

Electrical Engineering Professor Bir Bhanu and UCR Biology Professor John Heraty have been awarded a National Science Foundation grant to develop a framework for morphological image databases for insects that would facilitate automated species identification. Professor Bhanu is the Principal Investigator for the effort, which also involves several other biologists from UCR and the University of Pennsylvania who work with insects. An interactive system will help the computer learn concepts of biological entities with some initial feedback from the user, and over time the computer will become “smart”, providing the right answer to queries.

This research will have a broad impact in both life sciences and information technology. The form and structure of organisms are critical for understanding their evolution, diversification and relationships, especially in the case of insects which may have as many as 80 million species. It will also impact health, as the ability to rapidly identify pest organisms at ports of entry or in agricultural stations will facilitate quarantining of imports and reacting to biological invasions. Intelligent image search methods will allow image identification based on photographs, greatly speeding up the time it takes to identify organisms on a worldwide basis, and laying the foundation for future image and video database retrieval systems analogous to current text-based search engines.

Two awards to refine laser use in medicine

August 29, 2007

Mechanical Engineering Associate Professor Guillermo Aguilar and two colleagues from Mexico have received two awards from UC MEXUS (University of California Institute for Mexico and the United States), an academic research institute that encourages, secures and contributes to binational and Latino research and collaborative academic programs and exchanges. The funding will support a post-doctoral researcher and a visiting professor who will work in Dr. Aguilar’s lab.

Visiting Professor Santiago Camacho-Lopez (l.), a graduate of the Imperial College of Science, Technology and Medicine in the U.K., will work with Dr. Aguilar’s team for four months, evaluating specific laser effects and damage confinement of nano and fematosecond laser pulses on liver, red cells, epithelial and endothelial cells. His continual interaction with UCR students and the training he will receive on the handling of biomaterials will benefit the students, himself and his group at the Center for Scientific Research and Higher Education of Ensenada (CICESE).

Dr. Lorenzo Martinez-Suastegui (r.) is a Mechanical Engineering postdoctoral researcher from The National Autonomous University of Mexico (UNAM). Founded in 1551, UNAM is the largest university in Latin America. Dr. Martinez will work with Dr. Aguilar’s team for one year. His project is centered around the development of experimental methodologies that prove the feasibility of Laser-Assisted Cryosurgery (LAC), a novel approach developed by Professor Aguilar and co-workers. He will measure temperature variations and penetration depth of the frozen boundary on diverse cancerous tissues subjected to simultaneous cryofreezing and laser irradiation.

These awards will enable Drs. Camacho-Lopez and Martinez-Suastegui to benefit from new research experiences and close interaction with Dr. Aguilar’s group. At the same time, this interaction with Dr. Aguilar’s graduate and undergraduate students will be instrumental in furthering the students’ research projects and training.

Camps spark girls’ interest in engineering

July 30, 2007

Local girls aged 11-17 are experiencing what it’s like to be an engineer at a two-week summer camp and a one-week residential camp at Bourns College of Engineering sponsored by the San Gorgonio Girl Scout Council. Both camps teach the young participants how the engineering process works as they do hands-on projects, are mentored by female engineers, and go on field trips, including one that goes behind the scenes at Disney’s California Adventure to see how rides are designed.

“Engineer IT Girls” is a resident camp that took place July 22 to July 27. Projects that solve practical problems were conceptualized and demonstrated by the girls, who organized a display of their work for friends and family at the end of the program.

“Minds for Design” is a Monday through Friday day camp running from July 30 to August 10. Workshop sessions teach how a clock works, and explain gears, crankshafts and LEDs (Light Emitting Diodes). Structural considerations, budgets, prototypes and marketing are covered during project design, culminating in a Fair and demonstrations on the last day.

Both programs seek to increase the number of young women that want to become involved in the fields of engineering, science, technology and math. The girls are encouraged to ask questions and take a trial-and-error approach to problem solving, and record their experiences in notebooks. In the photo from the first day, the girls are coming up with toothpaste cap innovations.

Engineer teams with entomologist

July 23, 2007

Computer Science & Engineering Professor Eamonn Keogh, in collaboration with Dr. Agenor Mafra-Neto of ISCA technologies in Riverside, has been awarded a grant from the Army to create “Algorithms for Image Content Indexing and Information Retrieval from Unstructured or Semi-structured Complex Database”. The project involves building a tool to allow military intelligence officers to quickly search through massive collections of image data. While collaboration between an engineer and an entomologist may seem like an unlikely starting point for such research, Dr Keogh and Dr. Mafra-Neto impressed the Army with their experience in indexing and classifying images and videos of insects. The project for the Army will allow operators deployed in Iraq to photograph improvised explosive devices and quickly search an image database for similar devices, thus providing useful information on how to de-fuse the device. Researchers will also build a library of vehicles, weapons, tire and shoe treads for matching visual similarities. This technology could be further commercialized for a variety of uses, such as graffiti identification and e-commerce (“find me a handbag that looks like this one”).

Improving models for “smart” systems

July 11, 2007

Electrical Engineering Professor Jay Farrell has won three years of funding from the National Science Foundation (NSF) to investigate and develop self-organizing approximation-based control methods for systems such as aircraft subject to aging and damage, autonomous underwater vehicles, respirator air volume control and internal combustion engines. His studies focus on methods and conditions necessary to guarantee good repeatable performance for machines subject to the laws of physics acts – for instance, an aircraft that suffers in-flight damage. His research will improve the performance of current “smart” systems that adjust to changes in the environment or operating conditions while in use; better modeling will result in better controls. The concept is analogous to the growth of the nervous system within a biological entity as it learns new motor-control tasks. Funding for the project will directly support the education of engineering graduate students.

Miller’s new method lowers greenhouse gases

July 5, 2007

J. Wayne Miller, Associate Director of the College of Engineering–Center for Environmental Research and Technology (CE-CERT), has earned recognition from the Environmental Protection Agency (EPA) for developing a test that will, for the first time, allow scientist to accurately gauge the contribution of jet aircraft particulate emissions to global climate change. The Joint Strike Fighter (JSF) Test and Data Quality Assurance Team, of which Miller was a key member, includes university, Navy, EPA, industry and NASA personnel. Their combined resources, skills and expertise developed a new test methodology to quickly, accurately and economically measure particulate matter (PM) emissions from aircraft gas turbine engines. A result of several years of testing of both commercial and military gas turbine engines, it also significantly reduces engine run times, lowering greenhouse gas and criteria air pollutant emissions and cutting the overall cost of engine testing by over $1,000,000 per aircraft engine tested. In the team photo, Miller is standing at right.

  • Korotkov on cover of New Scientist

    May 18, 2007

    Two recent papers coauthored by Electrical Engineering Professor Alexander Korotkov are the basis for the May 12 cover story of New Scientist magazine. One paper (published in Science) presents an experiment on partial quantum measurement proposed by Dr. Korotkov and conducted by Prof. John Martinis’s group at UC Santa Barbara. The other paper, in collaboration with Prof. Andrew Jordan of the University of Rochester and published in Physical Review Letters, proposes an even more advanced experiment, which would show how to undo partial quantum measurement (so-called "quantum un-demolition"). The proposed experiment contradicts the commonly accepted point of view in quantum theory and could rewrite our understanding of reality. “It's a true cliffhanger,” says the New Scientist. Will Korotkov and Martinis save Schrödinger's cat, the most famous feline in physics, whose life is endangered by a quirk of quantum theory?

    Nanotubes provide option for molecular-scale computers

    February 12, 2007

    Mechanical Engineering Professor Qing Jiang’s research on oscillating carbon nanotubes has been reported in PhysOrg, a national web-based news site specializing in science and technology, and will appear in print in the journal Nanotechnology. Dr. Jiang and co-author Jeong Won Kang have discovered that when one hollow nanotube is placed inside a slightly larger nanotube and placed between electrodes, they can achieve a telescoping motion and behave as a switch that can be applied to binary or triple digit memory for molecular scale computers. Their device could provide nonvolatile memory, eliminating the need for secondary storage devices such as external hard drives. Jiang feels it is likely that a functioning prototype of a molecular processor will be demonstrated in the next two or three years, although commercialization faces challenges such as the lack of infrastructure for mass production.

He spoke of the challenges of climate change, saying dealing effectively with them is only possible through new thinking and understanding, and by effective integration of specific and overall policies for building, energy and transportation.

    ASME chapter captures national grant

    January 22, 2007

    For the second year in a row, the UCR chapter of the American Society of Mechanical Engineers (ASME) has been chosen to receive a Diversity Action grant from the national organization. Only 23 such grants were awarded nationally this year. The chapter received a check for $1,000, which will help to sponsor the College’s annual Space, Science & Engineering Day for elementary and middle school Girl Scouts and their families. The award was created to increase the number of students who pursue engineering education. ASME will be joined by the UCR chapter of the Society of Women Engineers to plan and staff the event, where children engage in a number of fun and educational activities such as making constellations inside a planetarium, participating in rocket races and making craters. JPL, NASA and the Riverside Astronomical Society are also involved, providing equipment and sharing their expertise. Pictured from left to right are Albert Yi, Karel Jansen and Michael Sheppy holding the check, and Oren Bordo.

    Liao’s research could result in diabetes pill

    January 16, 2007

    Bioengineering Assistant Professor Jiayu Liao is major player in a team that discovered a small molecule called Boc5, targeting Glucagon-like peptide (GLP1) receptor 1, that can cure diabetes in mice. This molecule can sensitize insulin function in responding to a high level of glucose, as well as reduce body weight by 20 percent. The discovery of a small molecule agonist for GLP1 receptor has been very difficult in the past. If it proves to be effective in humans, it can be turned into a drug that would be easier to use than current Type 2 diabetes medicine that must be injected twice a day. This molecule is also the first small molecule agonist for Class B GPCRs, which are involved in many human physiological processes. US scientist Andrew Young is also part of the team, as well as Ming-Wei Wang, director of China’s National Center for Drug Screening in Shanghai. The study was published in the Proceedings of the National Academy of Sciences, and has been reported by the Washington Post, Business World Online and Yahoo! News.

    Professors improve retention, attract scholarships

    January 8, 2007

    Professors Sheldon Tan and Frank Vahid (l. to r.) have successfully improved engineering student retention at UCR through a grant from the Semiconductor Industry Association (SIA). Their efforts have attracted the attention of the Verizon Foundation, which will augment the program with four scholarships for undergraduates studying Electrical Engineering. These scholarship recipients will work with the SIA students on events, programs and mentoring activities designed to create a sense of community. Vahid and Tan’s SIA program has concentrated on improving the social interaction of students, and non-course-related interactions with faculty. These factors have proven to be critical in retaining students, particularly those from backgrounds that do not include a tradition of attending college. Further techniques include group projects, a web-based system linking freshmen to one another, and meetings to teach study habits and success strategies. Retention improvement rose from 55 percent to 62 percent, and the number of women in the program increased from 7.8 percent to 16.7 percent, over one year.

    Student SWE chapter will host national event

    January 8, 2007

    UCR’s student chapter of the Society of Women Engineers (SWE) has been selected by the national organization to host their “Wow! That's Engineering?”outreach event in Fall 2007. Designed to bring young girls together with female engineers to learn more about the field of engineering through interactive activities and discussions, the program was kicked off last March in Chicago at the Museum of Science and Industry. Subsequent events took place in major cities. For this year’s events, SWE’s Career Guidance Committee reviewed 22 applications from 19 professional sections and 3 student sections from across the nation, and chose three sections: UC Riverside, Atlanta and Minnesota. Collaborators for West Coast event will include SWE National and the Orange County Professional Section. According to SWE, the demand for technology-savvy entrants in the workplace is growing three times faster than all other occupations, while enrollment in science-related courses is declining -- particularly among young girls. SWE is making an effort to change the current perspective of science, engineering, and technology fields among girls; less than ten percent of American engineers today are women. UCR SWE members are pictured at last year’s national convention.

    Air Force invests in Shelton’s research

    January 2, 2007

    Christian Shelton, Computer Science & Engineering faculty member, has been awarded a US Air Force Young Investigator Award for his research on continuous time structured stochastic processes. Dr. Shelton’s research represents a new way to predict and control continuous processes used in such dynamic systems as communication satellites that must manage their connections and monitor the security of their channels as resources and threats change. His research will develop tracking and control algorithms for continuous time systems, and his code base will be made publicly available so that others can extend the work. The Air Force’s Young Investigator Research Program (YIP) supports scientists and engineers who have received Ph.D.s in the last five years and who show exceptional ability and promise for conducting basic research. Professor Shelton’s was one of only 21 awards, selected from 145 proposals submitted from across the nation. His was the only one chosen from the state of California.
