Geodesolver for the Geodesic Equation
NASA has a need to determine the distribution of dark matter around planets like Earth. Doing so necessitates the ability to repeatedly solve the geodesic equation in simulations of weakly interacting particles streaming through bodies described by a Schwarzschild metric. Geodesolver numerically solves the...
Briefs: Test & Measurement
In many chemical processes, it is often desirable to detect the presence, quantity, and/or qualities of certain chemicals of interest; for example, in many closed chemical processes (either batch or...
Briefs: Photonics/Optics
Researchers at the University of Texas at Dallas have solved a longstanding problem that has been plaguing the scanning tunneling microscope for more than 35 years: How to prevent...
Briefs: Sensors/Data Acquisition
The Fused Analytic Desktop Environment (FADE) provides analysts in information-driven fields with a range of analysis technologies — capable of handling ad-hoc data sources — integrated into a...
Briefs: Green Design & Manufacturing
Particle analysis is useful for determining chemical compositions in a wide range of disciplines, from ascertaining the source of a petroleum sample to duplicating a fragrance. The technique is appealing to...
Briefs: Electronics & Computers
A limitation of today's ultrasound devices is that they are difficult to use on objects that don't have perfectly flat surfaces. Conventional ultrasound probes have flat...
Briefs: Test & Measurement
The wetting behavior of a liquid on a solid surface is a phenomenon of significant practical importance. The angle of liquid-to-solid contact is important in areas such as adhesion,...
Briefs: Motion Control
Technology was developed that not only allows wheels to “know” when and how to rotate, but also enables them to work together in interactive teams. The new technology can be used wherever there is a need for...
Briefs: Test & Measurement
The giant rotor blades are one central part of a wind turbine. Researchers developed a rotor blade that makes more efficient use of large fluctuations in wind strength using a...
