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.

Journal of Physics C: Solid State Physics, 1971
The conventional boltzmann-vlasov equations are solved for the case of a hot plasma with collisions such as may correspond to the conduction electrons in a semiconductor. A collision term is used which contains two relaxation times corresponding approximately to the usual momentum and energy relaxation times.

Results in Mathematics, 1993
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 \(e^ k:= (\delta_{ki})_ i\) \((k\in \mathbb{K})\).

Interstellar grains represent an important constituent of matter in space. They are necessary to the cooling and heating mechanisms and play an important role in the gas phase composition of molecular clouds. In addition, metallic components are important because they carry the charge inside dense clouds regulating the ion-molecule chemistry in these ...

Acta Astronautica, 1980
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.

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.

In the Parmenides we find a first attempt at a classification of change into locomotion (phora) and alteration (alloiōsis) (138bc). This is later expanded (155e–156b) so that we get a tripartite scheme embracing (1) (a)generation (genesis) and (b) perishing, (2) locomotion and (3) alteration: (a) combination and separation (becoming one or many), (b ...

Some unusual space-filling solids
The Mathematical Gazette, 2004When identical copies of a solid can be packed together indefinitely to cover the whole of space and leave no gaps it is said to be space-filling . Usually only convex solids are considered in this context since, as Grünbaum and Shephard point out, non-convex space-filling solids can be ...

Generalized Orlicz Spaces. Locally Solid Group Topologies
Mathematische Nachrichten, 1990Let L be a Riesz space, let \(L_ 0\) be a \(\ell\)-group, let \(\tau_ 1\) be a locally solid group topology on \(L_ 0\), k,\(\ell \in {\mathbb{N}}\) and let t: \(L^+\to L^+_ 0\) be a monotone operator such that \(T(0)=0\) and \(T(f+g)\leq k \sup \{T(\ell f),T(\ell g)\}\) for all \(f,g\in L^+\).

Space Shuttle solid rocket booster dewatering system
17th Joint Propulsion Conference, 1981After the launch of the Space Shuttle, the two solid rocket boosters (SRB's) are jettisoned into the ocean where they float in a spar (vertical) mode. It is cost effective to recover the SRB's. A remote controlled submersible vehicle has been developed to aid in their recovery.
