Variable Dynamic Testbed Vehicle: Dynamics Analysis

Lee, A. Y.; Le, N. T.; Marriott, A. T. (1997-02)

The Variable Dynamic Testbed Vehicle (VDTV) concept has been proposed as a tool to evaluate collision avoidance systems and to perform driving-related human factors research. The goal of this study is to analytically ...

A Variable Potential Porous Silicon Carbide Hydrocarbon Gas Sensor

Ryan, M. A. (1995-05)

A sensor which is capable of detecting hydrocarbons and distinguishing among them at

A Variable Potential Porous Silicon Carbide Hydrocarbon Gas Sensor

Shields, V.B.; Ryan, M.A.; Williams, R.M.; Spencer, M.G.; Collins, D.M.; Zhang, D. (1995-09)

A silicon carbide sensor has been constructed that is capable of distinguishing between methane and propene. This could have applications with automobile emissions and chemical processing.

The Variable Radioisotope Heater Unit for the Cassini Spacecraft

Lyra, Jacqueline C.; Stultz, James W. (1994-06-20)

This paper describes the Variable Radioisotope Heater Unit; its development, performance, and effectiveness at controlling the temperatures for the Cassini spacecraft thruster clusters.

The Variable Radioisotope Heater Unit for the Cassini Spacecraft

Lyra, J. C.; Stultz, J. W. (1994-06)

Variable specific impulse high power ion thruster

Goebel, Dan M.; Brophy, John R.; Polk, James E.; Katz, Ira; Anderson, John (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2005., 2005-07)

The power, Isp and thrust of ion thrusters are constrained by ther fixed grid gap in the ion accellerator, which limits performance and life to a limited range in Isp and thrust.

A Variable Stability Test Vehicle for ITS Applications

Griffin, Daniel C.; Lee, Allan Y. (1996-08-05)

A variable stability test bed is under development for the National Highway Traffic Safety Administration (NHTSA). The Variable Dynamic Testbed Vehicle (VDTV) is being designed for research and testing of advanced collision ...

Marriott, A. T. (1996-08-05)

Variable Stars in the DDO 187 Dwarf Galaxy

Danielson, G.; Hoessel, J.; Saha, A. (1998-10)

Twelve pulsating variable stars have been discovered in the dwarf irregular galaxy DDO 187.

Variable-Scale Smoothing and Edge Detection Guided by Stereoscopy

Olson, C. (1998-06-23)

The edges that are detected are thus at the same scale in the world, rather than at the same scale in the image.

Variable-Selection Heuristics in Local Search for SAT

Fukunaga, A. (1997)

One of the important components of a local search strategy for satisfiability testing is the variable selection heuristic, which determines the next variable to be flipped.

Variablility of Fram Strait Ice Flux

Kwok, R.; Rothrock, D. A. (1998-05)

We estimate the winter sea ice export through the Fram Strait using ice motion from satellite passive microwave data. Sea ice motion (October through May)is obtained by tracking the displacement of common features in ...

Variation of Fractional Electron Density Fluctuations Near 0.1 AU From the Sun Observed by Ulysses Dual-Frequency Ranging Measurements

Woo, R.; Armstrong, J. W.; Bird, M. K.; Patzold, M. (1994)

This paper presents the results of determining fractional density fluctuations, which requires the measurement of absolute electron density as provided by dual-frequency observations of time delay or ranging conducted by ...

Variation of Great Lakes Water Levels Derived from Geosat Altimetry

Morris, C. S.; Gill, S. K. (1993)

A technique for using satellite radar altimetry data to estimate the temporal variation of the water level in moderate to large inland bodies of water (lakes, in particular) is described.

Variation of magnetic source layer characteristics on Mars

Raymond, C. A.; Smrekar, S. E.; McGill, G. E. (2003-04-06)

Variation of the Mindanao Current transport during 1997-2000 estimated from TOPEX/Poseidon Data and an OGCM

Lee, T.; Fukumori, I. (2002-02-11)

Variation of the Mindanao current transport during 1997-2000 estimated from TOPEX/Poseidon data and an OGCM

Fukumori, I.; Some, R. R. (2002-02-11)

Variations and climatology of CI0 in the polar lower stratosphere from UARS Microwave Limb Sounder measurements

Santee, M. L.; Manney, G. L.; Water, J. W.; Livesey, N. J. (2002)

The Microwave Limb Sounder (MLS) on board the Upper Atmosphere Research Satellite (UARS) measured the global distribution of stratospheric ClO over annual cycles for much of the 1990s, albeit with reduced sampling frequency ...

Variations in Cosmic Ray Modulation and Magnetic Field with Latitude Ulysses Observations

Smith, E. J.; Balogh, A.; McKibben, R. B.; Simpson, J. A. (1997-07-28)

Variations in Gravity Signatures at Venusian Coronae in Plains, Chasmata, and Hotspot Settings

Nunes, D.; Lawrence, K. S.; Smrekar, S. E. (1997-12-07)
