Nvidia’s headquarters in Santa Clara, Calif., stands as both a testament to, and a literal product of, the same chips and technologies that have fueled the company’s dramatic rise to a $4 trillion ...

NISAR, built jointly by NASA and India’s space agency and launched on Wednesday, will use radar to monitor tiny changes across our planet’s land and icy regions. By Kenneth Chang A new radar satellite ...

Abstract: Quadric surfaces are commonly seen geometries in man-made targets. In this article, a unified bidirectional scattering distribution function (BSDF) is analytically derived for general convex ...

The limited spatial sampling rates of conventional Shack–Hartmann wavefront sensors (SHWFSs) make them unable to sense higher-order wavefront distortion. In this study, by etching a known phase on ...

ABSTRACT: This work has successfully shown that the optimum of a quadratic response function with zero coefficients except that of the quadratic term lies at the origin. This was achieved by using ...

ABSTRACT: Fitting C2-continuous or superior surfaces to a set S of points sampled on a 2-manifold is central to reverse engineering, computer aided geometric modeling, entertaining, modeling of art ...
