A report presents additional information on the Mechanical System Design/Analysis Tool (MSAT) computer program, which was reported in "Program for Designing a Mechanical System" (LEW-16710, NASA Tech Briefs, Vol. 23, No. 9 (September 1999), page 32. To recapitulate: MSAT is a user-friendly, multidisciplinary software system that...

A collection of three reports presents an expanded discussion of the topic of "Optical Diagnostics of High-Pressure Liquid Fuel Sprays" (LEW-16701),NASA Tech Briefs, Vol. 23, No. 3 (March 1999), page 18a. The reports describe experiments in which fuel sprays representative of those in...

A proposed reciprocating pump would operate at a small stroke and would contain no sliding parts. The oscillatory motion of a piston in the pump could be provided by a magnetostrictive actuator, for example.

A paper describes the mathematical basis and some applications of a class of massively parallel algorithms for finite-difference numerical solution of some time-dependent partial differential equations (PDEs) on massively parallel supercomputers. In a radical departure from the traditional...

Spectrometers are used for applications such as chemical analysis, remote sensing, environmental measuring, and optical measurements. Most spectrometers utilize prisms and gratings, where the dispersion of light depends upon the angle and rotation of the grating. But gratings and other moving parts are...

An application program for scanning and storage of images and for retrieval of the images via the World Wide Web has been written in the Java programming language to be portable to any computer and operating system that support the Java Virtual Machine 1.02. The program can be run on one...

A wireless information network (WIN) is undergoing development for use by workers at locations scattered across Kennedy Space Center (KSC). This WIN could be a prototype of a larger network that would serve all of NASA; by logical extension, it could also be a prototype of commercial WINs. By use of a combination of...

Four computer programs enable the nearly real-time distribution, analysis, and display of data on temperature, relative humidity, and particle fallout measured by sensors in the Orbiter Processing Facility (OPF) and the Launch Pad Payload Changeout Room (PCR) at Kennedy Space Center. The...

An electronic circuit has been designed as a prototype of a device that determines whether critical electrical systems have been compromised because of pyrolysis of polyimide-insulated wires. This circuit can be modified to prevent further pyrolysis and to check for indications of...
