Evaluating Effects of Exhaust Heat Recovery Systems on Fuel Economy and Emissions

The exhaust heat recovery system (EHRS) in an automobile captures the thermal energy from exhaust and transfers it to the engine coolant. As the car warms up,...

Algorithm Enables Drones to Work in a Coordinated Approach

An algorithm was developed that enables a team of unmanned aerial vehicles (UAVs) to communicate and work toward a common goal. The tool could be used to improve security or capture images simultaneously over a large area.

Keeping Data Fresh for Wireless Networks

For wireless networks that share time-sensitive information on the fly, it's not enough to transmit data quickly: that data also needs to be fresh. Consider the many sensors in your car. While it may...

NIST/NASA Study Shows One Detector Doesn't Fit All for Smoke in Spacecraft

What had been a peaceful and productive mission for the six men aboard the Russian space station Mir, including U.S. astronaut Jerry Linenger, nearly became a tragic...

Power Outlet Analyzes Electrical Current Usage

Electrical interruptions, or “nuisance trips,” occur when a detector installed behind the wall trips an outlet's electrical circuit when it senses something that could be an arc-fault — a potentially dangerous spark in the electric line. The problem with today's arc-fault detectors is that...

Simulation Technique Models Material-Aging Process

The nation's aging infrastructure requires massive investment. Imagine if engineers could build structures with materials that do not degrade over time. A simulation technique was developed that could help engineers do just that.

Modification of SURFICE Code

As part of the continued thermal support for the Space Launch System (SLS) program, MSFC is constantly developing or modifying software tools to aid in analytical efforts to solve thermal issues and problems posed by the project. In some cases, existing software used by previous heritage programs provides an...

Comprehensive Software Simulation on Ground Special Power at Kennedy Space Center

As the number of channels, or operative sites, increases in present and future ground special power (GSP) development efforts, the amount of hardware required to test development codes becomes substantially expensive. By simulating/emulating the hardware, code...

Information Sharing Protocol VCR (ISPVCR)

The Information Sharing Protocol (ISP) VCR (ISPVCR) is a software program written in Tcl/Tk that provides the capability to record and play back ISP data (telemetry, computations, ground system status, etc.) via Source Independent Telemetry Format (SITF) files. The ISPVCR provides a graphical user...

Location Awareness Algorithm for Internet of Things Devices

Positioning of wireless devices is centralized, depending on “anchors” with known locations such as cell towers or GPS satellites to communicate directly with each device. As the number of devices increases, anchors must be installed at higher density. Centralized positioning can...

Active Response Gravity Offload System

NASA has used two systems to train astronauts for weightlessness. The first is the Reduced Gravity Simulator that suspended the astronaut at an angle of 80.5 so that only 1/6th of his or her weight was supported by the ground, while the rest was supported by a pulley system. The other system, designed...
