Taking flight



More than 100 students in Mark Anderson's MAE 2 class, most of them freshmen, were out on Warren Field Monday December 8 to take part in a airplane launch competition. The students got together in teams of three and armed with glue guns and some ingenuity, built small motorized model airplanes out of balsa wood and foam board. The plane that would fly the longest would win. The catch was that the planes' motor only worked for 20 seconds.
"They learn about the dominant forces," Anderson said.
"Many said they realized how important weight is," he added.
After the winner was announced, all students got to launch their crafts at the same time, in a flurry of wings--and a few crashes.

Awesome pictures taken from more than 80,000 feet above the earth


We are in awe of these beautiful pictures taken by the Triton Rocket Club's space balloon at more than 80,000 feet above the earth.
The balloon is the club's testing platform for the electronics they plan to mount on a rocket hey will be launching in spring 2015. Their goal? To make UC San Diego the first university to launch a rocket in space.
In case you're wondering, you can see the Salton Sea in some of the pictures, as well as the Pacific Ocean.

J.S. Chen elected as the President of Engineering Mechanics Institute (EMI) of ASCE

J. S. Chen, William Prager Professor of Structural Engineering Department and Director of Center for Extreme Events Research at the UC San Diego Jacob School of Engineering, has been elected as the President of Engineering Mechanics Institute (EMI) of the American Society of Civil Engineers (ASCE) effective October 1, 2015. 

The missions of EMI are to serve the engineering community through the development and application of engineering mechanics by anticipating and adapting to new challenges that will face tomorrow's engineers; to create an environment that facilitates professional growth to ensure that these future challenges will be met; to establish a presence at the forefront of new thrusts of mechanics by promoting the most innovative developments in the field, regardless of the discipline of the ultimate user; to provide a home not only for those involved in the traditional disciplines, but also for those involved with emerging areas of mechanics; and to promote the interdependence of engineering mechanics and other disciplines by providing an interdisciplinary forum for researchers, practicing engineers, industry representatives, citizen groups, public officials and others.

 Center for Extreme Events Research

The Center for Extreme Events Research at UC San Diego has been established to offer solutions to a wide range of challenges associated with extreme events based on the most advanced computational and experimental technologies. Challenges we address are:


PROTECT THE NATION’S BUILT INFRASTRUCTURE

Our advanced research programs support predictive as well as retrofit strategies to make critical infrastructures blast resistant and capable of withstanding man-made and natural disasters. Expertise includes simulation-based assessment of residual strength and structural failure estimation after disastrous events.

PERFORM EXTREME EVENT MITIGATION AND RECOVERY

We provide rapid assessment of damage after disastrous events using simplified and reduced-order computational and experimental techniques with the aid of available sensor data and visualization information. We also provide solutions for mitigation and retrofitting damaged infrastructure.

PROTECT BIO-SYSTEMS INJURY FROM EXTREME LOADING

We work to prevent or mitigate brain and body injury due to bomb blasts, car crashes and collisions on the football field. This is of great importance to the military as well as civilian sectors. The state of the art computational capabilities at the Center for Extreme Events Research allow a thorough understanding of the mechanisms behind injury and provide guidance for design optimization for injury prevention.

Ghenkis Khan's tomb in Mongolia,bats in Guatemala: Professor, alum discuss engineering in exploration

Ryan Kastner, a professor of computer science here at the Jacobs School, and Albert Lin, a Jacobs School alum and Qualcomm Institute research scientist, have some interesting items on their resumes, including exploring Mayan ruins in Guatemala while dodging bats, and horseback riding in the Mongolian plains to find the tomb of Ghenkis Khan. The two engineers were there to bring the latest technologies to archeological exploration sites.
In this episode of Computing Primetime, they recall some of their adventures, and the technologies behind them.
"We're at the beginning of an era of data driven exploration," Lin says.
