Strange new twist: Berkeley researchers discover Möbius symmetry in metamaterials

12/20/10 ScienceBlog — For years, scientists have been searching for an example of Möbius symmetry in natural materials without any success. Now a team of scientists, led by Xiang Zhang of UC Berkeley, has discovered Möbius symmetry in metamaterials - materials engineered from artificial "atoms" and "molecules" with electromagnetic properties that arise from their structure rather than their chemical composition. This discovery opens the door to finding and exploiting novel phenomena in metamaterials.

Energizing the energy agenda

12/14/10 — While climate change and carbon emissions are very much in today's headlines, what is less often discussed is the need to provide technological societies with the economic imperative to make changes in our global energy system.

Professional master’s opens for enrollment

12/14/10 — A man of compact build and modest manners, Coleman Fung (B.S'87 IEOR) is living proof that behind that unassuming demeanor could be lurking an engineering dynamo. Appearing in Sibley Auditorium on Nov. 19, Fung tossed aside his prepared remarks to engage the audience in a light-hearted exploration of the personality traits of an engineer. His talk, entitled “Preparing Engineers for Leadership,” was one of several events celebrating the launch of Berkeley Engineering's new professional master's, a one-year intensive program that combines in-depth technical studies with a core leadership curriculum in business skills like management and finance.

Uncommon in every way: Engineers in intercollegiate sports

12/14/10 — Consider these numbers: Of 35,838 students at Berkeley this year, 4,665 are engineers. Of 800 athletes in intercollegiate sports, only a handful-fewer than five at any one time-are working toward an engineering degree. The combination is rare because any sane, reasonable person would wonder: How on earth do you pursue one of Cal's most difficult academic programs while playing for its most demanding teams? In their own distinct way, three members of this rarefied circle, Richard Fisher, Sati Hsu Houston and Dustin Muhn, have managed to do it successfully. Read about them and watch them in action in a dynamic slideshow.

Wheels of change in South Africa

12/14/10 — More than 9 million South African children walk to school every day. Three million walk for more than an hour, and in the rural countryside, some walk more than four hours. “It's madness,” says Louis de Waal (M.S'72 CEE), who grew up in rural South Africa and spent his professional life designing and building thousands of kilometers of roads there, many of which opened up inaccessible places deep in the country's interior. Now retired, De Waal is on a mission to improve mobility for all South Africans, especially in rural areas. The goal, says the 73-year-old Cape Town resident, is to keep children in school and help adults reach work more easily, ultimately easing poverty and slowing the flood of people forced to move to urban areas for work.

Berkeley Engineering grad student uses Kinect to create flying AI robot

12/07/10 Eng Tips — EECS grad student Patrick Bouffard, working with Professor Claire Tomlin from the Hybrid Systems Lab, has used Microsoft's Kinect controller to create a quadcopter which can maneuver around obstacles autonomously. The developers attached the Kinect hardware to the device which delivers a point cloud to the on-board computer and allows the vehicle to map its surroundings and move about intelligently. A video documenting the project and posted on YouTube is on track for going viral.

New study on IP strategies advises academics on how to build startups

11/17/10 PRWeb — The Center for Entrepreneurship & Technology (CET) at UC Berkeley has published a report providing practical insight on how entrepreneurs implement effective intellectual property strategies while starting technology ventures within an academic setting. Understanding the mechanics of how academics innovate has become critical as universities increasingly replace private laboratories as a primary source of innovation.

Berkeley Engineering alum A.K. Pradeep mines the brain for marketers

11/17/10 San Francisco Chronicle — A.K. Pradeep (Ph.D.'88 EECS) is a neuromarketer: He studies the inner workings of the human brain to find out not how people react to an array of stimuli, but why. He advises companies of all kinds - from banking to pharmaceutical to grocery chains - on how the female brain is different from the male brain, and how the young brain is unlike an old brain.

Engineering with broad shoulders

11/04/10 — A key tenet of Berkeley Engineering is to educate leaders. To us, engineering leadership extends beyond simply creating new technologies and managing technology innovation. Truly transformative engineering leadership calls for a comprehensive understanding of the economic, legal, social and environmental implications of novel and emerging technologies and services in societal scale systems.

New Blum Center headquarters opens on north side

11/04/10 — With campus and national dignitaries on hand and a sunny Homecoming Friday as a backdrop, the doors of Richard C. Blum Hall officially opened on Friday, October 8. It was a big occasion to celebrate what one project architect called a "little jewel box" of a building, small in scale but grand in its historic origins and its lofty goals. The program it will house also bears the name of Richard C. Blum, Haas alumnus, UC Regent and global philanthropist who championed the center to mobilize Berkeley students and faculty against global poverty.

Flight delays cost more than just time

11/04/10 — Domestic flight delays put a $32.9 billion dent in the U.S. economy, and about half that cost is borne by airline passengers, according to a study led by UC Berkeley researchers and released last month. The comprehensive report analyzed flight delay data from 2007 to calculate the economic impact on both airlines and passengers, including the cost of lost demand and the collective impact of these costs on the U.S. economy. The report was commissioned by the Federal Aviation Administration to clarify key discrepancies in earlier studies.

The fine art of engineering restraint

11/04/10 — Amid the busy world of Massachusetts General Hospital, Dino Di Carlo (B.S.'02, Ph.D.'06 BioE) experienced a well-known but oft-forgotten truism: technologies need to be simple to have an impact. As a postdoc there, Di Carlo observed that complex diagnostic technologies used in complex biomedical experiments often exacerbated research challenges, resulting in higher data failure rates. Today, the young assistant professor teaches the art of engineering restraint to his bioengineering students at UCLA and employs it in his research.

Flight delays cost you $17B, cost U.S. $33B, UC Berkeley study shows

10/18/10 San Francisco Business Times — A study from UC Berkeley's Institute of Transportation Studies crunched numbers from 2007 for the Federal Aviation Administration for a report showing that domestic airline flight delays cost the U.S. economy some $32.9 billion a year, and passengers pay half that cost, or about $16.7 billion. Civil engineering professor Mark Hansen, lead researcher on the study, said it was the first time anyone had analyzed data this way, coming up with a direct cost.

UC researcher puts buildings through earthquakes

10/14/10 ABC News — It is an uncomfortable fact for Californians that most of the structures in which we live and work pre-date the latest earthquake building codes. So how will those buildings fare in the next big one and how can we best fix them? Wael Hassan's dissertation at UC Berkeley looks at older forms of structural engineering to see how they will hold in a major earthquake. (Video)

Bionic legs allow paraplegics to get up and walk

10/11/10 TIME Magazine — A robotic exoskeleton called eLEGS enables people who have been paralyzed below the waist to walk again. The technology, the latest in a line of "human augmentation robotics systems" that Berkeley Bionics has created with the Robotics and Human Engineering Laboratory at the University of California, Berkeley, is geared toward consumers -- the 6 million or so paraplegics in the U.S. who are bound to wheelchairs.

Overestimate fueled state’s landmark diesel law

10/08/10 San Francisco Chronicle — California grossly miscalculated pollution levels in a scientific analysis used to toughen the state's clean-air standards, and scientists have spent the past several months revising data and planning a significant weakening of the landmark regulation. The problem, and the revised counting method, came to light after Robert Harley, a UC Berkeley professor of environmental engineering, and a colleague at Lawrence Berkeley National Laboratory did their own evaluation, which was published in December in the journal Atmospheric Environment. Harley found that the board's estimates of nitrous oxide were too high by a factor of 4.5 and its estimate of particulate matter was off by a factor of 3.1, an extraordinarily high amount to be off scientifically. "The difference is large enough that it changes policy," Harley said.
