If people were computers, Srinidhi Varadarajan of Virginia Tech’s Department of Computer Science could enable them to go back to their youth to correct mistakes they made, adapt a jet engine to run a car, or change a part from one SUV engine to another as both vehicles sped down a highway side by side.
Of course, people aren’t computers and don’t need to do those things, but computers need to do equivalent processes. Varadarajan has come up with a computer technology he calls "Weaves" that allows the programmer to use a code in any programming language and convert it to a form similar to object-oriented programming. Weaves teachnology is used to create a virtual world that tricks the software into thinking it is in the real world.
The global computer network--the Internet--has doubled every year for nearly 20 years. The problem is how to test new pieces of network software on such a grand scale. The traditional method is through computer simulation, such as the model of a jet cockpit in which beginning pilots start to learn how to fly a plane. But simulation requires rewriting the software in a different form to test it, as the original cannot be tested. That creates two different versions, and there is no formal mechanism to ensure the equivalence of the test with the real thing, Varadarajan said.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
