hydraulic attributes play important role in hydrological studies, soil conservation, designing irrigation and drainage systems, soil conservation, and controlling soil erosion in watersheds. their measurements are very tedious and time consuming and due to high spatial variability, a large number of measurements are required for obtaining reliable values. nowadays, prediction of these attribute...

an analytical equation of state (eos) developed by ihm-song-mason (ism) has been applied tocalculate some thermophysical properties of molten polymers including poly (1-octene) (po), poly (vinylmethyl ether) (pvme), poly (vinyl chloride) (pvc), and poly (styrene) (ps). three temperature-dependentparameters of the ism eos have been determined based on the alternative scaling constants, dispersiv...

This paper describes a technique to animate three-dimensional sampled volumes. The technique gives the animator the ability to treat volumes as if they were standard polygonal models and to use all of the standard animation/motion capture tools on volumetric data. A volumetric skeleton is computed from a volumetric model using a multi-resolution thinning procedure. The volumetric skeleton is ce...

Introduction: Imaging radars with wavelengths in the range of 10 cm to 1 m can deeply penetrate the surface of an icy body, revealing details of the geo-morphology, local structure, and electrical properties of the upper layers. Radar studies of icy surfaces on Earth have used the polarization state of backscatter echoes at multiple frequencies to characterize the surface and subsurface propert...

The internal structure and petrophysical property distribution of fault zones are commonly exceedingly complex compared to the surrounding host rock from which they are derived. This in turn produces highly complex fluid flow patterns which affect petroleum migration and trapping as well as reservoir behavior during production and injection. Detailed rendering and forecasting of fluid flow insi...

BACKGROUND The partial specific volume of a protein is an experimental quantity containing information about solute-solvent interactions and protein hydration. We use a hydration-shell model to partition the partial specific volume into an intrinsic volume occupied by the protein and a change in the volume occupied by the solvent resulting from the solvent interactions with the protein. We seek...

In stored grains, smaller depositions and great variations with regard to theoretical insecticide doses are frequently found. The objective of this work was to evaluate the influence of the emulsifiable concentrate formulation on the physical properties of the liquid, volumetric distribution, droplet spectrum, and insecticide deposits on stored grains. To determine its physical properties, the ...
