Abstract: Models for the origin of the contrasts in the ultraviolet images of Venus are examined in an attempt to determine the physical differences between light and dark regions fundamental to a clear understanding of the apparent ...

Abstract: A recently developed constitutive model and a finite element formulation for predicting the thermomechanical response of shape memory alloy hybrid composite (SMAHC) structures are briefly described. ...

Abstract: Shape memory alloy (SMA) hybrid composites with adaptive-stiffening or morphing functions are simulated using finite element analysis. The composite structure is a laminated fiber-polymer composite ...

Abstract: Valves based on rotating geometry have long been sought by designers for their simplicity, compactness, and desirable dynamic properties. Unfortunately, they generally involve tight sealing surfaces with significant relative ...

Abstract: A global atmospheric model is developed with a computational efficiency which allows long-range climate experiments. The model solves the simultaneous equations for conservation of mass, energy and momentum, and the equation ...

Abstract: A method which allows for the comparison of polymer electrolyte fuel cell (PEFC) bipolar plates (BPs) with various channel dimensions is outlined here. It is applied to data from an experiment with different channel and ...

Abstract: Switchable multistable structures (SMS) are additively manufactured metamaterials. SMS are printed in polylactic acid, a shape memory polymer, and pre-strain is stored in bilayers during fused deposition modeling 3D printing ...

Abstract: Anthropogenic aerosols are composed of a variety of aerosol types and components including water-soluble inorganic species (e.g., sulfate, nitrate, ammonium), condensed organic species, elemental or black carbon, and mineral ...
