investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Transpose on vertex symmetric digraphs
In [2] (and earlier in [3]), we defined several global communication tasks (universal exchange, universal broadcast, universal summation) on directed or vertex symmetric networks. In that paper, we mainly focused on universal broadcast. In [4], we discussed universal sum. Here we continue this work and focus on universal exchange (transpose) in directed vertex symmetric graphs. Introduction. In...
متن کاملThe 19-vertex Model at Critical Regime |q| = 1
We study the 19-vertex model associated with the quantum group Uq(ŝl2) at critical regime |q| = 1. We give the realizations of the type-I vertex operators in terms of free bosons and free fermions. Using these free fields realizations, we give the integral representations for the correlation functions.
متن کاملSurface critical phenomena and scaling in the eight-vertex model.
We give a physical interpretation of the entries of the reflection K-matrices of Baxter’s eight-vertex model in terms of an Ising interaction at an open boundary. Although the model still defies an exact solution we nevertheless obtain the exact surface free energy from a crossing-unitarity relation. The singular part of the surface energy is described by the critical exponents αs = 2− π 2μ and...
متن کاملVertex corrections for impurity scattering at a ferromagnetic quantum critical point
We study the renormalization of a nonmagnetic impurity’s scattering potential due to the presence of a massless collective spin mode at a ferromagnetic quantum critical point. To this end, we compute the lowestorder vertex corrections in twoand three-dimensional systems for arbitrary scattering angle and frequency of the scattered fermions, as well as band curvature. We show that only for backw...
