Counting on Grains of Sand

08-24-16

José E. Andrade, Professor of Civil and Mechanical Engineering; Executive Officer for Mechanical and Civil Engineering, and colleagues have developed a new method that measures the way forces move through granular materials—one that could improve our understanding of everything from how soils bear the weight of buildings to what stresses are at work deep below the surface of the earth.

The Utility of Instability

08-08-16

Professors Dennis M. Kochmann and Chiara Daraio along with colleagues from Harvard have designed and created mechanical chains made of soft matter that can transmit signals across long distances. Because they are flexible, the circuits could be used in machines such as soft robots or lightweight aircraft constructed from pliable, nonmetallic materials. "Engineers tend to shy away from instability. "Though there are many applications, the fundamental principles that we explore are most exciting to me," Kochmann says. "These nonlinear systems show very similar behavior to materials at the atomic scale but these are difficult to access experimentally or computationally. Now we have built a simple macroscale analogue that mimics how they behave." [Caltech story]

Richard Murray Named to DOD Panel on Innovation

07-28-16

Richard M. Murray, Thomas E. and Doris Everhart Professor of Control and Dynamical Systems and Bioengineering, has been named to the Defense Innovation Advisory Board by Secretary of Defense Ash Carter. Professor Murray joins 14 other scholars and innovators who will focus on new technologies and organizational behavior and culture. Secretary Carter has asked them to identify technology and practices from the private sector that could be used by the Department of Defense (DOD). [Caltech story]

Schroeder
Improving Computer Graphics with Quantum Mechanics

07-27-16

The Schrödinger equation, the basic description of quantum mechanical behavior, can be used to describe the motion of superfluids—fluids, supercooled to temperatures near absolute zero, that behave as though they are without viscosity. Professor Peter Schröder and his colleagues realized that the same equation with some small modifications can also be used to describe vorticity dominated phenomena of fluids at the macroscopic level--from smoke gently rising from a flame to the concentrated vorticity of a twister.

Counting L.A.’s Trees

07-27-16

Professor Pietro Perona, has developed a method using Google Earth and Google Street View to count the trees in the city of Los Angeles. The process of counting the trees using human tree counters is very expensive and would cost about $3 million today. The last time the city did such counting was more than two decades ago and at the time there were 700,000 street trees. Perona has tested the methodology in a section of Pasadena where the city recently commissioned a sidewalk survey. By comparing the results to the known inventory, he determined that the computer was about 80% accurate. [LA Times story] [KPCC story]

Kaushik-bhattacharya
Professor Bhattacharya Named Vice Provost

07-14-16

On July 15, 2016, Kaushik Bhattacharya, Howell N. Tyson, Sr., Professor of Mechanics and Materials Science, will take over from Professor Morteza Gharib as Caltech vice provost. His research group studies the mechanical behavior of solids and uses theory to guide the development of new materials. He has made contributions on a wide array of topics, ranging from the fundamental mechanics of materials, to active materials and devices, to multi-scale and multi-physics scale simulation of materials. Though trained as a theoretician, he is well known for live demonstrations of shape-memory materials in action.  "Kaushik's technical strength, deep knowledge of the Institute, energy, and enthusiasm will serve him and us well as he takes on this important role," said EAS Division Chair G. (Ravi) Ravichandran. [Caltech story]

Professor Doyle Receives Test of Time Paper Award

07-13-16

John Doyle, Jean-Lou Chameau Professor of Control and Dynamical Systems, Electrical Engineering, and Bioengineering, and colleagues have received the ACM SIGCOMM Test of Time Paper Award for their paper, A first-principles approach to understanding the Internet's router-level topology. The award recognizes papers published 10 to 12 years in the past that is deemed to be an outstanding paper whose contents are still a vibrant and useful contribution today. [List of recipients]

A Microscopic Glowing Van Gogh

07-12-16

Paul Rothemund, Research Professor of Bioengineering, Computing and Mathematical Sciences, and Computation and Neural Systems, and colleagues have developed a technique that allows manmade DNA shapes to be placed wherever desired; to within a margin of error of just 20 nanometers. This technique removes a major hurdle for the large-scale integration of molecular devices on chips. As a demonstration of the technique’s capabilities the group has created one of the world's smallest reproductions of Vincent van Gogh's The Starry Night. [Caltech story]
