Fast Derivation of Soil Surface Roughness Parameters Using Multi-Band SAR Imagery and the Integral Equation Model
The Integral Equation Model (IEM) predicts the normalized radar cross section (NRCS) of dielectric surfaces given surface and radar parameters. To derive the surface parameters fr...

Interactive Rendering of Non-Constant, Refractive Media Using the Ray Equations of Gradient-Index Optics
Existing algorithms can efficiently render refractive objects of constant refractive index. For a medium with a continuously varying index of refraction, most algorithms use the r...

Discontinuous Galerkin approximations of the Stokes and Navier-Stokes equations
Numerical schemes to compute approximate solutions of the evolutionary Stokes and Navier-Stokes equations are studied. The schemes are discontinuous in time and conforming in space...
