Conservative Sampling of Solids in Image Space
IEEE Computer Graphics and Applications, 2013Conservative sampling samples boundary-representation (B-rep) solid models into layered depth images (LDIs). The resulting models have a closed boundary and are guaranteed to bound the input B-rep models on the rays of LDIs. This approach can be fully implemented by shader programs supported by various graphics hardware.

Xenomict energy in cold solids in space
Naturwissenschaften, 2006Minerals on earth whose crystalline order has been reduced by radioactive decay of contained atoms are termed "metamict." They are rare and few because in most crystalline solids, atoms and vacancies are relatively mobile at terrestrial temperatures, and radiation damage tends to be self-annealing. This is not the case in the extreme cold of deep space.

A Topology for the Solid Subsets of a Topological Space
Canadian Mathematical Bulletin, 1993AbstractA new topology for the closed subsets of a topological space X which are the closure of their interiors is defined and investigated. Some applications to convergence of regular measures are also given.

Abstract The technology that has resulted in the application of solid propellant rocket motors to the space program is reviewed. Several unique large motor concepts first demonstrated in the 120-in. dia. Titan booster are discussed. Descriptions and development status reports for two major solid rocket propulsion systems are presented.

Let \(T= (t_{nk})\) be a row-finite matrix such that each column belongs to the space \(bv\) of sequences of bounded variation. The \(T\)-sections of a sequence \(x= (x_ k)\) are defined as \(t^ n x:= \sum_ k t_{nk} x_ k e^ k\), where \(e^ k:= (\delta_{ki})_ i\) \((k\in \mathbb{K})\).
