Routing Protocols for Mobile Ad Hoc Networkix years. Particular interest is drawn to a compressor life test initiated in August 1992. Two teardowns of this hardware have taken place for wear evaluation; these results are included in this report. An initial teardown after 10,600 hours of operation in a horizontal orientation indicated an aver

Data Dissemination and Broadcast Disksation test programs. Texas Instruments has designed a complete family of coolers for these tactical applications and has completed qualification programs successfully for two of these designs. Tested were the cryocoolers for the Integral Detector Assembly (IDA) and the Javelin antitank missile syste

Data Dissemination and Broadcast Diskspace applications with a typical-mean-time-to-failure (MTTF) goal of five years or more. The cost is expected to be about $1.0 million per cryocooler. Unbalanced tactical cryocoolers are readily available at comparatively low cost (< $20,000.00) with typical MTTF’s of about 2500–8000 hours. NASA/GSF

Electron-Beam-Induced Nanowire Assemblies,y JPL in a number of performance areas including thermal performance. A number of factors are used to evaluate the efficiency and cooling power of cryocoolers at cryogenic coldtip temperatures. A comparison of the measured thermal performance of several cryocoolers is presented..The various cryocool

Development for Space Use of BAe’s Improved Single-Stage Stirling Cycle Cooler for Applications in tplications. The design is based upon BAe’s well proven 80K cooler which is itself a direct derivative of the Oxford ISAMS cooler..The cooler operates in the range 50 to 80K with significantly improved efficiency and heat lift capacity (800 mwatt at 55K) when compared to the earlier BAe 80K cooler.
