The D***sub2*** Variation for Polydisperse Clusters of Lox Drops in Hydrogen at Supercritical Conditions

Bellan, J.; Harstad, K. (2000-07-30)

A study of polydisperse clusters of fluid drops at supercritical pressures has been conducted using a previously validated model of subcritical/supercritical isolated fluid drop behavior.
The D-2 variation for isolated LOX drops and polydisperse clusters in hydrogen at high temperaturen and pressures

Harstad, K.; Bellan, J. (2001-03)

A study of the d(2) variation for isolated fluid drops and for fluid drops belonging to polydisperse clusters has been conducted at a high temperature and elevated pressures.
D.R.O.P. The Durable Reconnaissance and Observation Platform

McKenzie, Clifford; Parness, Aaron (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2012., 2012-05-14)

The Durable Reconnaissance and Observation Platform (DROP) is a prototype robotic platform with the abil- ity to climb concrete surfaces up to 85◦ at a rate of 25cm/s, make rapid horizontal to vertical transitions, carry ...
D.R.O.P: The Durable Reconnaissance and Observation Platform

McKenzie, Clifford (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2011., 2011-08)

Robots can provide a remote presence in areas that are either inaccessible or too dangerous for humans. However, robots are often limited by their ability to adapt to the terrain or resist environmental factors. The Durable ...

Dark current degradation of near infrared avalanche photodiodes from proton irradiation

Becker, Heidi N.; Johnston, Allan H. (Dark current degradation of near infrared avalanche photodiodes from proton irradiation, 2004-12-06)

InGaAs and Ge avalanche photodiodes (APDs) are examined for the effects of 63-MeV protons on dark current. Dark current increases were large and similar to prior results for silicon APDs, despite the smaller size of InGaAs ...

Dark Material in the Polar Layered Deposits on Mars

Herkenhoff, K. E.; Vasavada, A. R. (1998-05)

Viking infrared thermal mapping (IRTM) and bistatic radar data suggest that the bulk density of the erg material is much lower than that of the average Martian surface or of dark dunes at lower latitudes.
