Professor Rolf Sabersky Passes Away


Rolf H. Sabersky, Professor of Mechanical Engineering, Emeritus, passed away on October 24, 2016 at the age of 96.  Professor Sabersky joined the faculty in 1949 having obtained his BS ’42, MS ’43, and PhD ’49 from Caltech in Mechanical Engineering. He became professor emeritus in 1988.  He worked with luminaries throughout his distinguished career including Theodore von Kármán at Aerojet. James Van Allan sought his expertise for the development of the Ajax and Bumblebee rocket programs.  Professor Sabersky made pioneering contributions to our understanding of boiling heat transfer, free convection, granular flows, and indoor air quality. He taught courses in thermodynamics, fluid mechanics, and heat transfer.  He was renowned for his commitment to education, mentoring, and promoting diversity. He was the author of two popular textbooks, Elements of Engineering Thermodynamics, and Fluid Flow: A First course in Fluid Mechanics, which he coauthored with Professor Allan Acosta. He received the Heat Transfer Memorial Award from the American Society of Mechanical Engineers in 1977.

Visualization Brings Data to Life


Students participating in Caltech's Data Visualization program aim to tackle cumbersome data-manipulation problem such as how to drive a rover on Mars from a command room on Earth. One of the goals of the program is to develop innovative software to streamline the ways in which scientists and engineers visually manipulate their data. "We use a human-centered design methodology," Professor Mushkin says. "Design students create sketches and ask the researchers to 'interact' with them by pointing, talking, shuffling, and annotating the paper, while computer science students create rough drafts of a variety of possible approaches to coding the visualization."

Mechanics of Materials Across Nano to Geological Time and Length Scales


A symposium was organized at Brown University on September 16-17, 2016 to celebrate the technical contributions of Professor Ares Rosakis on the occasion of his 60th birthday. The symposium was chaired by Professors Pradeep Guduru, Huajian Gao, and G. Ravichandran. It brought together distinguished engineers and scientists from multiple disciplines to discussion research frontiers relating to the mechanics of materials across nano to geological time and length scales.

Modular Space Telescope Could Be Assembled By Robot


Professor Sergio Pellegrino and colleagues including Professor Joel Burdick, are proposing a space observatory with a 100 meters diameter primary mirror. Their design calls for the use of more than 300 deployable truss modules that could be unfolded to form a scaffolding upon which a commensurate number of small mirror plates could be placed to create a large segmented mirror. In this concept, a spider-like, six-armed "hexbot" would assemble the trusswork and then crawl across the structure to build the mirror atop it. [Caltech story]

Counting on Grains of Sand


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


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


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]

Professor Bhattacharya Named Vice Provost


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]
