POLYHEDRON DISTORTIONS IN TOURMALINE
The Canadian Mineralogist, 2002Distortion parameters [?, s2, DI(Y-O), DI(O-Y-O), DI(O-O)] have been calculated for cation polyhedra in tourmalines of different chemical compositions. Tourmalines with greater amounts of small, highly charged ions in the YO6 octahedron display greater bond-length distortion in Y. The size and charge of the occupants at the Y site have been included in

In this study, we developed an audio system that is made up of speaker system of regular polyhedron enclosure, and multi channel digital audio amplifier. The speaker system has loudspeaker units that are independently wired out of the enclosure, and are controlled independently. The amplifier can control their output timing and amplitudes independently

1. Introduction. Let P be a polyhedron (i.e., a 3-dimensional polytope). A path in P is defined as a sequence of edges (x1, x2), …, (xi−1, xi), (xi, xi−1), …, (xn−1, xn) where (xi, xi+1) denotes the edge with endpoints Xi and Xi+1. Define the length |A| of a path A to be the number of edges of said path. The distance between any two vertices x and y of

Abstract We derive multi-bladed polyhedron propellers after a new principle. The remarkable structures of Coxsackievirus a21 and Human Rhinovirus Complexed with ICAM-1 are given as examples.

The Continuous Mixing Polyhedron
Mathematics of Operations Research, 2005We analyze the polyhedral structure of the sets PCMIX = {(s, r, z) ∈ R × R+n × Zn ∣ s + rj + zj ≥ fj, j = 1, …, n} and P+CMIX = PCMIX ∩ {s ≥ 0}. The set P+CMIX is a natural generalization of the mixing set studied by Pochet and Wolsey [15, 16] and Günlük and Pochet [8] and recently has been introduced by Miller and Wolsey [12].
