Best Paper at Green Computing Conference


Professor Adam Wierman, along with students Zhenhua Liu and Minghong Lin have received the Best Paper award at the IEEE Green Computing Conference for their paper "Online algorithms for geographical load balancing". The paper provides near-optimal algorithms that can cloud services to implement "follow the renewables" routing, and to take advantage of solar and wind energy.

Calculating the Capacity of a Network


Michelle Effros, Professor of Electrical Engineering, and information theorist colleagues have begun to tackle the difficult problem of calculating capacities for large communication networks such as the internet and mobile phone networks. In two recent publications, they introduce techniques useful for improving the performance of current communication networks and for designing the networks of the future. By demonstrating where current technology falls short of what's possible, these techniques provide a new tool for strategically guiding research and development. [Read the Publications]

Robust Self-Replication


Erik Winfree, Professor of Computer Science, Computation and Neural Systems, and Bioengineering, and colleagues including Caltech alumnae Rebecca Schulman, have created a new system to copy sequence information. In their approach, tiny DNA tile crystals consisting of many copies of a piece of information are first grown, then broken into a few pieces by mechanically-induced scission, or force. The new crystal bits contain all the information needed to keep copying the sequence. Each piece then begins to replicate its information and grow until broken apart again—without the help of enzymes, an essential ingredient in biological sequence replication. [Caltech Press Release]

Better, Stronger, Lighter Armor


Kaushik Bhattacharya, Howell N. Tyson, Sr., Professor of Mechanics and Professor of Materials Science, is the Caltech lead on a $90 million U.S. Army Research Laboratory funded program to improve protective gear and vehicles for soldiers. "…studying materials in very extreme conditions is an area where Caltech engineering really stand out," says Bhattacharya. "The tools we bring, on both the theoretical and experimental sides uniquely bridge deep fundamental principles with unprecedented application.” [Caltech Feature]

Greater Insight into Earthquake Cycles


Nadia Lapusta, Professor of Mechanical Engineering and Geophysics, and colleagues have developed the first computer model of an earthquake-producing fault segment that reproduces, in a single physical framework, the available observations of both the fault's seismic (fast) and aseismic (slow) behavior. "Earthquake science is on the verge of building models that are based on the actual response of the rock materials as measured in the lab—models that can be tailored to reproduce a broad range of available observations for a given region," says Lapusta. "This implies we are getting closer to understanding the physical laws that govern how earthquakes nucleate, propagate, and arrest." [Caltech Press Release]

Paul MacCready Papers to be Digitized


The MacCready family have made a generous gift for the processing and digitizing of the papers of Caltech alumnus, inventor and entrepreneur Paul B. MacCready (1925-2007).  Paul B. MacCready pioneered alternative energy solutions through his company,  AeroVironment. In the mid-1970s he began work on the celebrated human-powered Gossamer aircraft series, beginning with the Gossamer Condor. He continued to work on the problems of solar-powered flight and unmanned aircraft, but his interest in environmentally friendly technology also led him to innovative electric and hybrid automotive vehicles, micro-air vehicles and the high altitude, long endurance Helios solar aircraft for telecommunications, imaging and scientific research.

The MacCready digitization project will be the first on the part of the Caltech Archives to make an entire paper, artifact, image and analog media collection available on the internet to the widest possible public.  [Archives News]
