Check out the GreenDroid page run by the researchers in the Department of Computer Science and Engineering (CSE) at UC San Diego. The professors leading the research are Steven Swanson and Michael Taylor. This work was presented recently at the HotChips symposium in Palo Alto.

Experimental Batteries in the Works / NanoEngineers in Action

A student assembles an experimental battery in the Department of NanoEngineering at the UC San Diego Jacobs School of Engineering. The work is being done in the Laboratory for Energy Storage and Conversion run by NanoEngineering professor Shirley Meng.

How do Whales Hear?

UCSD structural engineering professor Petr Krysl has designed modern computational methods that give a 3D simulated look inside the head of a Cuvier’s beaked whale.

Researchers led by a UC San Diego structural engineering professor are working to understand the potential harmful effects of sound on marine mammals such as whales and dolphins.

The researchers led by Petr Kryls have developed a model that creates a 3-dimensional virtual environment in which they can simulate sounds propagated through the virtual specimen and reveal the interactions between the sound and the anatomy. By having a virtual “peek” inside the whale’s head, the scientists are able to better understand and see how sound may impact or potentially harm marine life. Read the full story by Andrea Siedsma on the Jacobs School site.

“Humans introduce considerable amounts of sound and noise into the oceans of the world,” Krysl said. “Many marine organisms make acute use of sound for their primary sensory modality because light penetrates so poorly into water. The primary focus of our work is Cuvier's beaked whale because some have stranded and died in the presence of Navy sonar. The discoveries we made with regard to the mechanisms of hearing in the beaked whale also apply to the bottlenose dolphin and, we suspect, to all types of toothed whales and perhaps other marine mammals.”

The work was recently published in the journal PLoS One: "A New Acoustic Portal into the Odontocete Ear and Vibrational Analysis of the Tympanoperiotic Complex"

UC San Diego Cut Electricty Purchases During Heat Wave Last Week

During Aug. 23-25 when California’s afternoon temperatures rose above 100 degrees, UC San Diego took a variety of energy-conservation steps, including simultaneously adjusting thousands of thermostats a few degrees warmer than normal to help cut electricity purchases up to 80 percent during three state-wide “demand response” events.

UC San Diego faculty and staff switched from desktop computers to more energy-efficient laptops and turned off printers and other office equipment not in use and took many other measures as part of an effort to restrain electricity consumption. As a result, UC San Diego reduced its purchase of electricity from 10.5 megawatts to only 2 megawatts during a critical two-hour period on Aug. 25 and reduced electricity purchases by similar amounts during the two previous afternoons.

Surf Video on Engadget

The UC San Diego science of surfing project from MAE undergrads and a Structural engineering graduate student made its way engadget to this week. The full story is here.

The exposure pushed one of the two related surfing videos on YouTube to almost 10,000 views. Check out the second Jacobs School surfing video on YouTube here.
