Boeing Dreamliner Landing Gear Braces Tested at UC San Diego Jacobs School of Engineering

Jacobs School structural engineering professor Hyonny Kim led testing of the first-ever composite landing gear braces, which were used for the new Boeing 787 aircraft, which took off for the first time today. (New York Times story here.)

Kim is an associate professor in structural engineering at the UCSD Jacobs School of Engineering, and he led a team of researchers that performed six months of rigorous Federal Aviation Administration tests on the composite landing gear braces.

“This was a very important test,” Kim said. “The quality standards of the testing, and keeping track of the data and documentation (for FAA certification) is extremely high. For us, we had to improve our methods and processes to get to be able to perform at the FAA certification level and we did. We have proven that we can do this level of testing. We have the facility and equipment and capability to do it. What we hope with this project is to demonstrate to the aerospace industry that UC San Diego is capable of and can perform aerospace certification testing for future projects.”

French Aerospace company Messier-Dowty tapped into the expertise of structural engineering professor Hyonny Kim this year to test the strength and durability of the first-ever composite landing gear braces for the commercial aircraft industry.

Energy Efficient Computing on Multiple Scales

"Energy is one of the key issues to be solved in order for systems to work more efficiently," said UC San Diego Jacobs School of Engineering professor Tajana Simunic Rosing, who is leading MuSyC's Large-Scale Systems effort. "At a very small scale such as a brain-machine interface, without energy you cannot do anything at all. At a very large scale such as a data center, if you are not efficient about how you deal with energy, you go bankrupt."

This quote is from a Calit2 press release announcing Jacobs School computer science professor Tajana Simunic Rosing as one of the leaders of a new research center charged with finding ways to improve the design of computing systems ranging from large data centers to tiny brain sensors. In its first three years, the Multi-Scale Systems Center (MuSyC) will focus on tackling a critical issue affecting multiple scales: energy efficiency.

Albert Lin, a Materials Science alumnus named an adventurer of the year

Jacobs School alumnus Albert Lin (Ph.D. 2008)is one of the world's top adventurers, according to National Geographic Adventure magazine. Below are a couple of paragraphs from the Calit2 story on the award.

It’s not often that a materials scientist by training gets to be labeled one of the world’s top adventurers. But that’s the honor bestowed on Calit2 research scholar Albert Yu-Min Lin, 28, in the December 2009-January 2010 issue of National Geographic Adventure magazine. Lin is affiliated with Calit2’s Center of Interdisciplinary Science for Art, Architecture and Archaeology (CISA3).

Lin earned his Ph.D. in materials science and engineering from UC San Diego’s Jacobs School of Engineering in 2008. After graduation, “his mother, a former Hong Kong movie star, and his father, an astrophysicist, both urged him to get on with things as soon as possible, to find a job that would allow him to eat more steak, less ramen,” writes Luke Dittrich in the feature article, “Conjuring the Great Khan”, that is part of NG Adventure’s cover story. “Instead, Lin decided to begin his post-[doctoral] graduate career by organizing a high-risk, high-stakes project, one that offered little stability and even less promise of success.”

How big is a zettabyte?

How big is a zettabyte and why might you care? Calit2's Doug Ramsey recently wrote a story that looks at how much information Americans are taking in. It also explains just how big a zettabyte is and what zettabytes have to do with you. (The New York Times and many other outlets covered the story this week.)

"The average American consumes about 34 gigabytes of data and information each day — an increase of about 350 percent over nearly three decades — according to
a report published Wednesday by researchers at the University of California, San Diego," the NYTimes wrote.

In the Calit2 story, Larry Smarr says:

"What is clear is that we consume orders of magnitude more information than can be stored on hard drives or transmitted over today's Internet," said Internet pioneer Larry Smarr, Director of the California Institute for Telecommunications and Information Technology (Calit2) and a computer science professor at the UC San Diego Jacobs School of Engineering. "Even small changes in how Americans consume information would have serious implications for network planners and require large-scale investments."

Heart Mending with Stem Cells

Bioengineering professor Adam Engler and bioengineering Ph.D. student Jennifer Young landed in Technology Review today. Journalist Lauren Gravitz covered their presentation on Tuesday at ASCB 2009 where they reported advances in using embryonic stem cells (from chickens) to regenerate heart cells.

The big idea is that the bioengineers are working to re-create the physical consitions and cues within organisms that guide (at least in part) the differentiation process from stem cells to heart cells.

KPBS covered Cell Phones, Sensors and Pollution Monitoring Story

Ed Joyce from KPBS, the San Dieog NPR station, ran a story on the new pollution monitoring system being developed by computer scientists at the UC San Diego Jacobs School of Engineering.

Here is the cell phone and pollution monitoring story from KPBS.

San Diegans, Cell Phones, Air Pollution Monitoring Network

“San Diego County has 3.1 million residents, 4,000 square miles, and only five official EPA air quality monitors. We know about the air quality in those exact spots but we know much less about the air quality in other places. Our goal is to give San Diegans up-to-the-minute environmental information about where they live, work and play—information that will empower anyone in the community to make healthier choices,” said William Griswold, the principal investigator on the grant and a professor in the Department of Computer Science and Engineering (CSE) at the UC San Diego Jacobs School of Engineering.

So here is the deal: everyone has cell phones. What if those phones could be used to transmit environmental information collected by tiny, inexpensive sensors hanging from your backpack or board shorts...transmit that info to centralized computers that analyze it and send insights back to regular folks in real time?

That's the plan that computer scientists are putting into action now that they have a $1.5 million grant from the National Science Foundation (NSF).
