Multichannel Decomposition and Isomerization of Octyl Radicals

October 9, 2008
Author(s)
Wing Tsang, William S. McGivern, Jeffrey A. Manion
… at temperatures in the 850-1000 K range and pressures near 2 bar.  Rate constants for the six beta bond scission and … state) have rate constants that are within a factor of 2 of those for the 1-4 process (six member cyclic transition state).  It appears that rate constants for 1-2 H-transfer isomerization, involving an eight member cyclic …

Flits: Pervasive Computing for Processor and Memory Constrained Systems

William J. Majurski, Alden A. Dima, Mary T. Laamanen
… pervasive computing software technologies are targeted for 32-bit desktop platforms. However, there are innumerable 8, 16, and 32-bit microcontroller and microprocessor-based embedded … capable of executing across a wide variety of 8, 16, and 32-bit processors and offering mobile code and high level …

Superconducting Multiplexer for Arrays of Transition Edge Sensors

June 28, 1999
Author(s)
James A. Chervenak, Kent D. Irwin, Erich N. Grossman, John M. Martinis, Carl D. Reintsema, Martin Huber
We report the design and testing of an analog superconducting time-division multiplexer to instrument large format arrays of low-temperature bolometers and microcalorimeters. The circuit is designed to multiplex an array of superconducting quantum

Evaluation of Flammable Refrigerants for Use in a Water-to-Water Residential Heat Pump

September 3, 1996
Author(s)
D K. Choi, Piotr A. Domanski, David Didion
… the performance of R-22, R-290, R-290/600a (70/30), and R-32/152a (50/50) for application in a water-to-water … of results for the same system capacity showed R-32/152a to be the best performer due to good glide matching … with an earlier simulation study where R-290/600a and R-32/152a had a similar COP. The test data showed that the …

Unique File Identification in the National Software Reference Library

October 24, 2006
Author(s)
Steven L. Mead
The National Software Reference Library (NSRL) provides a repository of known software, file profiles, and file signatures for use by law enforcement and other organizations involved with computer forensic investigations. This paper examines whether the

Adhesion at layer-by-layer surfaces in aqueous environments

February 15, 2009
Author(s)
Adam J. Nolte, Jun Y. Chung, Marlon L. Walker, Christopher M. Stafford
Adhesion between materials is often governed by the ambient environment, which can mediate or change the types of molecular interactions present at an interface. Biological interactions, for example, can be mediated by factors such as temperature, ionic

Subsurface Patterning and its Effect on Interfacial Adhesion

February 15, 2009
Author(s)
Edwin P. Chan, Christopher M. Stafford
Nature (e.g. geckos and insects) has illustrated that a patterned surface can effectively tailor the adhesion of an interface. Inspired by the amazing attachment and detachment ability of these animals, significant efforts have been put forth to understand
