Stress - strain isotherms and thermoelastic properties of crosslinked amorphous polyoxyethylene in compression
(Elsevier, 1975-05)
Stress-strain isotherms at a number of temperatures in the range 45-85[deg]C have been determined for a compressed, amorphous polyoxyethylene network swollen with a constant amount of non-volatile diluent. The observed ...
The preparation and some reaction of F2PSPF2 and F2PC(CF3)2OPF2, and the synthesis of the bis-borane adduct of F2PSSPF2
(Elsevier, 1976)
The potentially bidentate fluorophosphine ligand F2PSPF2 can be prepared in 75% yield from the reaction of F2PBr and [(C4H9)3Sn]2S. On the basis of infrared and Raman spectra, the compound has been assigned a bent confirmation ...
Picosecond X-ray diffraction studies of laser-excited acoustic phonons in InSb
(Springer-Verlag, 2002-10)
We have employed time-resolved X-ray diffraction with picosecond temporal resolution to measure the time-dependent rocking curves of laser-irradiated asymmetrically cut single InSb crystals. Coherent acoustic phonons were ...
Simulation and theory of abnormal grain growth--anisotropic grain boundary energies and mobilities
(Elsevier, 1989-04)
Abnormal grain growth has been studied by means of a computer-based Monte Carlo model. This model has previously been shown to reproduce many of the essential features of normal grain growth. The simulations presented in ...
Development of a Time-Resolved Laser-Induced Fluorescence Technique for Nonperiodic Oscillations
(2016)
Time-resolved measurements of ion dynamics could be key to understanding the physics of instabilities, electron transport, and erosion in Hall thrusters. Traditional measurements of the ion velocity distribution in Hall ...
Faster AFS
(Center for Information Technology Integration, 1992-06-22)
The AFS Cache Manager fetches files from the AFS file server, and caches them into a local file system. Given this model, users expect reads of locally cached files to perform at local file system rates. However, read ...
Finite Element Modeling of Longitudinal Metastructures for Passive Vibration Suppression
(American Institute of Aeronautics and Astronautics, 2016-01-01)
Novel Foot Orthosis
(2006-12)
The objective of this design project is to implement a device capable of resting the posterior Thetibialis tendon (for less advanced stages of PTT), or (for more advanced cases) to perform the functions of the tendon by ...
