Computer Scientists Assist with Conservation Planning

08-16-11

Postdoctoral Scholar Daniel R. Golovin and colleagues including Professor Andreas Krause have won the Outstanding Paper Award in the Computational Sustainability and Artificial Intelligence Track at the 2011 Association for the Advancement of Artificial Intelligence (AAAI) Conference  for their paper entitled Dynamic Resource Allocation in Conservation Planning. The paper was selected from 975 submissions.  It addresses how computer science (in particular machine learning and adaptive optimization) can help conservation planning, by making recommendations about how to best protect rare species.

Disorder Is Key to Nanotube Mystery

08-12-11

William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics; and Posdoctoral Scholar Tod Pascal believe to have solved the mystery of why water spontaneously flows into extremely small tubes of graphite or graphene, called carbon nanotubes.  Using a novel method to calculate the dynamics of water molecules they have found that entropy is the missing key.  "It's a pretty surprising result," says Professor Goddard "People normally focus on energy in this problem, not entropy."

Cell-phone Medical Devices

08-08-11

Mani Chandy, Simon Ramo Professor and Professor of Computer Science; Deputy Chair for Education, and Julian J. Bunn, Principal Computational Scientist at CACR, are working with a group of Summer Undergraduate Research Fellowships (SURF) in CMS, EE, and MCE to building a collection of medical devices that can be connected to a cell phone. "We want to exploit cell-phone technology and the Internet to provide inexpensive health-care tests for the poor in remote rural villages," says Chandy. [Caltech Feature]

Engineers Solve Longstanding Problem in Photonic Chip Technology

08-04-11

Liang Feng, a Postdoctoral Scholar in Electrical Engineering who works with Professor Axel Scherer, has designed a new type of optical waveguide - a 0.8-micron-wide silicon device. The waveguide allows light to go in one direction but changes the mode of the light when it travels in the opposite direction. This new technique to isolate light signals on a silicon chip, solves a longstanding problem in engineering photonic chips. [Caltech Press Release]

Kobiloarov
Best Paper Finalist in Robotics

07-24-11

Marin Kobilarov, a W. M. Keck Institute for Space Studies Postdoctoral Fellow, was a finalist for the best paper award in the 2011 Robotics: Science and Systems Conference - his paper is entitled Cross-Entropy Randomized Motion Planning .  The conference committee solicited original papers in all areas of robotics and followed a highly selective review process designed to select the best work of its kind in every category. Dr. Kobilarov is working on discrete geometric motion control of autonomous vehicles with Professors Mathieu Desbrun and Sergio Pelligrino.  [Read the paper]
