The program encompassed an analytical and experimental investigation of the application of passive thermal control techniques to extravehicular flexible space garments in 300 nautical mile earth orbits. Results indicate that passive thermal control by varying the absorptance and emittance of the outer surface of the garment is not possible when internal heat generated is in excess of 1500 Btu/hr. For all conditions, the suit's solar absorptance should be as small as possible and its emittance...

Internal waves, traveling beneath the ocean surface with maximum amplitude at or near the pycnocline, have been observed in various areas of the oceans. This report reviews what is known concerning the generation, prevalence, and characteristics of internal waves, and summarizes available knowledge concerning the effects of internal waves on naval operations. Internal waves affect naval operations in two principal areas--depth control and detection capability. The passage of large-amplitude...

This is the report on an eight-month exploratory study of U.S. industrial preparedness in an arms control environment. The methodology adopted for the analysis was a combination of macro- and microeconomics. The macroeconomic approach involved first a forecast of the U.S. economy into the 1980's assuming no mobilization and then an estimate of the broad impact on that economy should a mobilization of specified dimensions actually occur. The microeconomic analysis, designed to test the...

A part of the theory of search in the presence of false contacts was formulated and developed. Some properties of searches, such as additivity and compatibility, that play a central role in the theory of search, were studies. The expected-time problem was formulated for the case in which false contacts are generated by real objects, and a method of solution was found when the number of false targets is known to be finite with a known distribution. Two problems involving moving targets, without...

We built and tested a device intended to render diesel fuel acceptable to a 250W portable POX based fuel processor. The premise, established by chemical kinetics analysis, was that diesel fuel is reformable by POX once its polyaromatic compounds are removed and its naphthenes and olefins cracked. Our device utilized a single plate still to separate those species already light enough to reform from those species heavy enough to require further treatment. Further treatment consisted of a cracking...
