the electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting hamiltonian anderson tunneling method. in this paper we concentrate on the configuration of the quantum dot rings. we show that the asymmetric structure of qd-scatter system strongly influences the amplitude an...

wire-brushing is used for different purposes such as removing metal surfaces oxides, increasing surface brightness, improving fatigue properties and surface activation before coating. the wire-brushing severely scratches and stirs the metals in the surface layers, so that complicated metal flow gives rise to very large amount of plastic strain and increases dislocation density of the surface la...

Despite reports of frequent complications, pin and tension- band wire remains the most common repair of simple olecranon fractures and osteotomies. A recent mechanical study found wire diameter to be the key determinant of pin and tension-band construct strength; models with 1.25-mm wire were much stronger than those with standard 1.0-mm wire exposed to single loads to failure. Additionally, fi...

This paper addresses the task of nuisance reduction in twowire speaker recognition applications. Besides channel mismatch, two-wire conversations are contaminated by extraneous speakers which represent an additional source of noise in the supervector domain. It is shown that two-wire nuisance manifests itself as undesirable directions in the interspeaker subspace. For this purpose, we derive tw...

OBJECTIVES To investigate the reproducibility of wire codes to characterise residential power line configurations and to determine the extent to which wire codes provide a proxy measure of residential magnetic field strength in a case-control study of childhood leukaemia conducted in nine states within the United States. METHODS Misclassification of wire codes was assessed with independent me...

a 3-year-old arabian colt was presented for a major gingiva wound at the right rostral part of mandible. after clinical assessments, rostral mandibular fracture was determined. stabilization of fractured region was achieved via cerclage wire application under general anesthesia. fixation wires were left in place for 6 weeks. a 3 -month follow up revealed complete fracture healing. the purpose o...

statement of problem: fracture strength of a denture base resin is of great concern, and many approaches have been used to strengthen acrylic resin dentures. purpose: the aim of this study was to measure the transverse strength of a heat polymerized acrylic resin, after reinforcement with metal wire and two types of glass fibers. materials and methods: forty rectangular specimens (65.0×10.0×3.3...

In this paper, we consider non-uniform wire-sizing. Given a wire segment of length L, let f(x) be the width of the wire at position x, 0 x L. We show that the optimal wire-sizing function that minimizes the Elmore delay through the wire is f(x) = ae ?bx , where a > 0 and b > 0 are constants that can be computed in O(1) time. In the case where lower bound (L > 0) and upper bound (U > 0) on the w...
