System and Method for Space Utilization Optimization and Visualization

The program uses a standard Web browser to allow for visualization of an entire organization down to individual rooms.NASA’s Langley Research Center has developed a space-allocation and planning software system to allow for more effective and efficient facility usage. It also provides a customizable strategy for organizing personnel and project teams to maximize productivity and synergies among employees. Cost-reduction solutions are suggested based on organizational input constraints related to the facility. The program uses a standard Web browser to allow for visualization of an entire organization down to individual rooms. The planning tool is based on algorithms that were developed using ArcGIS software and Visual Basic codes, which enable evaluation of different space-management scenarios in real time.

Reducing Sensor and Readout Circuitry Noise in Digital Domain Using Reference Pixels

One of the main heritage tools used in scientific and engineering data spectrum analysis is the Fourier Integral Transform and its high-performance digital equivalent — the Fast Fourier Transform (FFT). The Fourier view of nonlinear mechanics that has existed for a long time and the associated FFT carry strong a-priori assumptions about the source data, such as linearity and being stationary. Natural phenomena measurements are essentially nonlinear and nonstationary.

Method and Software Tool for Evaluation and Automated Generation of Space Habitat Interior Layouts

The software can help design space habitats, submarines, ships, aircraft, recreational vehicles, and small residences.NASA has developed a new software tool for optimizing interior layout designs of highly constrained, highly integrated, and/or confined spaces, such as space habitats. This tool will automatically generate or evaluate interior layout options while taking into account multiple end-user objectives. Development and evaluation of interior layouts are often ignored during conceptual design because of the subjectivity and long times required using current evaluation methods (e.g., human-in-the-loop mockup tests and in-depth CAD evaluations). The NASA tool will allow for early, more objective assessment that will prevent expensive design changes, which can increase vehicle mass and compromise functionality.

Airborne Wind Profiling Algorithm for Doppler Wind Lidar

This novel method enables accurate, real-time parameter estimation in noisy environments.NASA’s Langley Research Center has developed an algorithm, Airborne Wind Profiling Algorithm for Doppler Wind Lidar (APOLO), that offers highly accurate, real-time measurement of wind parameters (i.e., direction and speed) by airborne wind lidar sensors. APOLO enables the extraction of accurate wind speed and direction from noisy flight environments, and provides correction for instrument installation biases. The algorithm has been incorporated into a supporting software package that displays accurate airborne Doppler wind lidar data, and offers several data post-processing and display functionalities. The offset compensation and parameter extraction technology could be used in a variety of applications where the motion and orientation of a lidar sensor may result in data inaccuracy. NASA is seeking licensees that may benefit from integration of the compensation algorithm and data post-processing software into existing or developing systems.

NETMARK Fast Search

Applications include enterprise knowledge management, and document and content management systems.The problem that motivated this work was one of analyzing hundreds of thousands of records of historical problem failure reports (aka, problem reports and corrective actions — PRACA) for improved mission safety. Whenever there is an anomaly in mission design or operations, the anomaly gets entered into a problem failure reporting database for tracking purposes. The objective of the research was to make this data queryable and analyzable using the NETMARK XML database.
