The FDA has signed a five-year collaborative research agreement with Dassault Systèmes Vélizy-Villacoublay, France, a world leader in 3D design software, for the development of testing paradigms for insertion, placement, and performance of pacemaker leads and other cardiovascular devices...

Commercial triple junction solar cell designs were modified in their junction thicknesses, contact grid densities, and anti-reflective (AR) coating thicknesses to better match the Mars surface solar spectrum. Resulting cells show up to approximately 8% relative improvement in efficiency under the Mars solar spectrum,...

Orbiting a large number of satellites in fixed formations will be critical to many future space missions, especially large-scale interferometers, telescopes, antennas, and gravity wave detectors. Consequently, extensive research has been devoted over the last 20 years to formation...

Peak-seeking algorithms optimize physical processes in real time and are widely used throughout a variety of industries. However, measuring associated parameters in changing conditions, and responding to them appropriately, is difficult because the measurements are typically distorted by noise. This technology addresses...

An enterprise middleware solution allows disparate information technology (IT) systems to be integrated into one seamless, efficient system. As software and database platforms continue to develop at an accelerated pace, legacy systems can be a drain on resources, requiring complex workarounds and major code...

A suite of software tools was developed that enables powerful and efficient processing of time history data. These tools can be used together or independently, offering a variety of capabilities including comparison of time history data files to validate pre-processing activities, conversion...

Cryptography and molecular biology share certain aspects and operations that allow for a set of unified principles to be applied to problems in either venue. A DNA-inspired hash code system is presented that utilizes concepts from molecular biology. It is a keyed-Hash Message...

The Station Spacewalk game enables players to virtually conduct NASA repair work on the International Space Station, including jobs critical to help power up the space station so it can continue to operate. Players are provided with a limited quantity of oxygen during which they must complete extravehicular activities (EVAs) and...

Scientists at the VTT Technical Research Centre of Finland have demonstrated a new technique for harvesting energy from mechanical vibrations of the environment and converting it into electricity. They explain that energy harvesters are needed, for example, in wireless self-powered sensors and medical...

This week's Question: NASA has worked with industry to help create the Synthetic Vision System (SVS), a virtual reality display system for cockpits. The SVS uses 3D to provide pilots with intuitive means of understanding their flying environment, including graphical displays of terrain and hazards. In...
