The term "coherent phase line enhancer" (CPLE) refers to a dual-transform method of spectral analysis that enhances the detection of periodic and quasi-periodic signals buried in wide-band noise. The CPLE is particularly useful for increasing the signal-to-noise ratios of spectral peaks...

MECS is a computer program for the automated, secure, rapid, and efficient transfer of data between a central source and users at multiple distant locations. "MECS" signifies "Multi-mission Encrypted Communication System." MECS enables many users to collaborate securely on a shared plan or set of data.

Real-Time Net Transfer (RTNT) software allows for efficient and reliable transport of raw, GPS (Global Positioning System) observables over the open Internet. Efficiency is achieved by editing and compressing the GPS observables at the remote site, and by using User Datagram...

The Common Database Interface and Report Generator is a computer program that serves as both (1) a single common interface for data-base application programs to gain access to local or remote data bases by use of Structured Query Language (SQL) operators and (2) a report generator.

The DataSlate computer program is being developed to help educators and students gain access to, view, manipulate, and otherwise interact with sets of planetary and other scientific data via the Internet or via local data-storage facilities. DataSlate will be especially useful for displaying...

An Airfield Wind Advisory System (AWAS) includes a self-contained weather station, located at an airfield, that measures speed and direction of the wind, the temperature, the barometric pressure, and the humidity. This ground station digitizes these measurements and transmits the measurement data...

A computer program performs a unified analysis of the radiation exposure, the temperatures, and the power generation and distribution for predicting the performance of the TOPEX satellite on orbit and during maneuvers. The unified analysis is needed because all aspects are...

Parameter Identification in Thermal Networks (PITN) is a computer program developed to satisfy a need to update parameters in mathematical models of thermal systems in order to make the temperatures computed by the models equal to the temperatures measured in tests of the corresponding real...

Solid State Recorder Pointer Tracker (SSRPT) is a computer program developed specifically to aid ground-based monitoring and control of two redundant solid-state recorders (SSRs) aboard the Cassini Spacecraft. The SSRs store telemetry data until downlink times, which are limited to a...

The Platform Independent Software Components for the Exploration of Space (PISCES) software library provides for web-based, collaborative development of computer programs for planning trajectories and other trajectory-related aspects of spacecraft-mission design. The PISCES library...

A continuing program of research and development focuses on engineering of functional cartilage and cardiac muscle for scientific research and for eventual use in transplants. The program involves the use of cells, polymer scaffolds, and bioreactor vessels. A polymer scaffold serves as a three-dimensional structure...

Wavelength-independent light couplers in the form of planar arrays of pyramids have been proposed for use on multiple-quantum-well infrared photodetectors. Wavelength-independent light couplers are needed for focal-plane arrays of QWIPs designed to operate in multiple and/or broad...
