Reynolds number and cowl position effects on the internal shock structure and the resulting performance of a generic three-dimensional sidewall compression scramjet inlet with a leading edge sweep of 45 degrees at Mach 10 have been examined both computationally and experimentally. Prior to the experiment, a threedimensional Navier-Stokes code was adapted to perform preliminary parametric studie...

High P-T Raman measurements of solid and fluid hydrogen to above 1100 K at 70 GPa and to above 650 K in 150 GPa range, conditions previously inaccessible by static compression experiments, provide new insight into the behavior of the material under extreme conditions. The data give a direct measure of the melting curve that extends previous optical investigations by up to a factor of 4 in press...

Two problems arise when semi-static word-based compression methods are applied to large texts, such as those stored in information retrieval systems. First, the space required for the model during decoding can become very large. Second, the need to handle document insertions means that the collection must be periodically recompressed if compression eeciency is to be maintained. Here we show tha...

Ice VI has been produced by shock compression of ice I h to about 2 GPa. This is the second high-pressure polymorph of water observed in shock loading. These experiments point out the ease with which high-pressure phases can form when ice I h is impacted. The new shock data, combined with previous static measurements, provide preliminary equation of state parameters for ice VI of V = 0.7732 m3/...

The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions. The results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. This is due to the Ti(CN) and TiC precipitates and also the free carbon content. In the ferrite reg...

Unacylated ghrelin, the predominant form of circulating ghrelin, protects myotubes from cell death, which is a known attribute of pressure ulcers. In this study, we investigated whether unacylated ghrelin protects skeletal muscle from pressure-induced deep tissue injury by abolishing necroptosis and apoptosis signaling and whether these effects were mediated by SIRT1 pathway. Fifteen adult Spra...

Energetic materials are extensively used as propellants in rockets demanding the understanding of their chemical and thermal stability for safe storage transportation well ease decomposition. Nitromethane (NM) is one such material with significant performance advantage over other mono propellants. In this manuscript, we report detailed molecular-level behavior NM under static dynamic compressio...

Current adaptive compression schemes such as gzip and compress are impractical for database compression as they do not allow random-access to individual records. The sequitur scheme of Nevill-Manning and Witten also adaptively compresses data, achieving excellent compression but with signiicant main-memory requirements. A preliminary version of sequitur used a semi-static modeling approach to a...
