GoldSim Technology Group LLC, of Issaquah, Washington, a privately held software company that delivers software and services to help people understand complex systems and make better decisions worked with NASA to advance GoldSim, the company's namesake simulation software, originally developed for...

Digital Imaging is the computer processed numerical representation of physical images. Enhancement of images results in easier interpretation. Quantitative digital image analysis by Perceptive Scientific Instruments, locates objects within an image and measures them to extract quantitative...

The digital interface board will control the phase and amplitude of the signals for each element in the array. A host computer running Agilent VEE sends commands via serial UART connection to a Xilinx VirtexII FPGA. The commands are decoded and either outputs are set or telemetry data is sent back...

The charters of Freedom Monitoring System will periodically assess the physical condition of the U.S. Constitution, Declaration of Independence and Bill of Rights. Although protected in helium filled glass cases, the documents are subject to damage from light vibration and humidity. The photometer...

DRAT directly overcomes RAT's limitations and brings code auditing and open source license analysis into the realm of Big Data using scalable open source Apache technologies. DRAT was funded by DARPA XDATA and is already being applied and transitioned into the government.

Reviving industry standards for coating parts in tungsten disulfide, a dry lubricant developed for the Mariner space probes managed by the Jet Propulsion Laboratory in the 1960s and _70s, Applied Tungstenite, a relatively new Temecula, California-based company, has found a client base in the...

This software is designed to reduce risk, design cost, and implementation cost of theDSN modernization. This work has a direct impact on the cost and available volume of space communications, which are major drivers of mission design and NASA planning.

DspaceOgre can be useful for robotics technology development. It will also be useful for basic research in molecular dynamics modeling. DspaceOgre is a general purpose 3D graphics visualization C tool designed for the visualization of simulation and analysis data for articulated mechanisms...

Unlike all Internet mechanisms for security distribution (e.g., certificate authorities), DTKA operates over the extremely long signal propagation times and interrupted links that characterize communication with interplanetary spacecraft. It has no single point of failure and cannot be "spoofed" by...

DTNTAP is a userspace Ethernet driver with the potential to expedite DTN deployment by providing a transition mechanism for legacy IP (Internet Protocol) applications to run alongside delay and disruption tolerant applications in large scale communication networks. By presenting an Ethernet-like...
