The interpretation of satellite-observed radiances to derive cloud optical depth and effective particle size requires radiative transfer calculations relating these parameters to the reflectance,… (More)
A computer model for simulating pressure and flow propagation in the human arterial system is developed. The model is based on the one-dimensional flow equations and includes nonlinearities arising… (More)
The Clouds and the Earth’s Radiant Energy System (CERES) is part of NASA’s Earth Observing System (EOS). CERES objectives include the following. 1) For climate change analysis, provide a continuation… (More)
Three contrail systems were analyzed with geostationary satellite data to document the conversion of the contrails to cirrus clouds. Two unique contrails, a pair of figure eights and a NASA DC-8… (More)
The kinetics and distribution of methotrexate in intraventricular and intrathecal cerebrospinal-fluid spaces were studied in patients with meningeal leukemia and meningeal carcinomatosis after drug… (More)
Objective techniques have been developed to consistently identify cloudy pixels over nonpolar regions in multispectral imager data coincident with measurements taken by the Clouds and Earth's Radiant… (More)
We studied 85 cancer patients with lumbosacral plexopathy and documented pelvic tumor by CT or biopsy. Three clinical syndromes were delineated: lower (L4-S1), 51%; upper (L1-L4), 31%; and… (More)
The National Aeronautics and Space Administration's Clouds and the Earth's Radiant Energy System (CERES) Project was designed to improve our understanding of the relationship between clouds and solar… (More)
