Low cost multi-channel GPS receiver
An investigation was conducted on compact, multichannel GPS (global positioning system) receivers. The code generator and correlation equipment were simplified, attempting to avoid downgrading the properties possessed by ...
A knowledge-based control paradigm for real-time systems
The authors examine the application of knowledge-based symbolic control to the management of execution and configuration of a complex numerical control system. Symbolic processing is used to implement inference of system ...
Semimetallic Behavior in Fe2VAl: NMR Evidence
(American Physical Society, 1998)
We report the results of a 27Al and 51V nuclear magnetic resonance study of Fe2VAl at temperatures between 4 and 550 K. This material has been a subject of current interest due to indications of possible heavy fermion ...
Band-edge properties of a semiconductor alloy: An NMR study of Hg1−xCdxTe
(American Physical Society, 1993)
We report Hg199 NMR measurements of narrow-gap Hg1−xCdxTe alloys in the range x=0.20–0.28. By studying temperature dependences, we have identified intrinsic Knight shifts in these alloys. This provides a measure of Hg ...
NMR studies of NbSe3: Electronic structures, static charge-density-wave measurements, and observations of the moving charge-density wave
(American Physical Society, 1990)
We describe a series of Nb93 NMR studies of the charge-density-wave (CDW) conductor NbSe3. Using an aligned, multicrystalline sample, we have measured the complete shift tensors for the three Nb sites in the normal state. ...
NMR study of the structure and motion of charge density waves in NbSe3
(American Physical Society, 1986)
The authors report NMR measurements of the Nb93 resonance in the charge-density-wave (CDW) conductor NbSe3 on aligned, multicrystalline samples. They have observed the resonance with and without current flow in the sample ...
Potentials for High-Energy Scattering from Hydrogenlike Atoms
(American Physical Society, 1970)
Pion flow and antiflow in relativistic heavy-ion collisions
(American Physical Society, 1996)
Within the framework of a relativistic transport model (ART 1.0) for heavy-ion collisions at AGS energies we study the transverse flow of pions with respect to that of nucleons using two complementary approaches. It is ...
Measurement of Ann, Ano, and Aon for the Reaction Pp-]D-Pi+ in the Energy Region 500-800 Mev
(American Physical Society, 1987)
