We develop a simple systematic method, valid for all strengths of disorder, to obtain analytically the full distribution of the conductance P g for a quasi-one-dimensional wire in the absence of electronelectron interactions. We show that in the crossover region between the metallic and insulating regimes P g is highly asymmetric, given by an essentially “one-sided” log-normal distribution. For...

Abstract. In this paper the effect of asymmetric rolling on possibility increasing technological plasticity aluminum alloys was investigated. The experimental research carried out a laboratory mill with an individual drive work rolls creating speed ratio from 1.0 to 5.0. It shown that increase 5.0 significantly reduce force in comparison symmetric rolling. Rolling decreased 1.9 times for alloy ...

In this paper we consider some factors that could improve the high rate performance of the RPC; we consider the role of freon in the operation of RPCs and present results with an asymmetric RPC with one glass and one melamine resistive plate. Presented at the Vienna Wire Chamber Conference, February 13-17, 1995 Proceedings to be published in Nuclear Instruments and Methods in Physics Research s...

Cameras with rolling shutters are becoming more common as low-power, low-cost CMOS sensors are being used more frequently in cameras. The rolling shutter means that not all scanlines are exposed over the same time interval. The effects of a rolling shutter are noticeable when either the camera or objects in the scene are moving and can lead to systematic biases in projection estimation. We deve...

 One of the surface defects that arise in sheet metal working is when the part removes from the die. Since there are no external forces to make this defect, the origin of such fail is known as residual stress. Residual stress can develop in sheet metal forming due to non uniform deformation. In this paper, the workpiece is carbon steel with different volume fractions and arrangement of ferrite ...

there is a complicated relation between cold flat rolling parameters such as effective input parameters of cold rolling, output cold rolling force and exit thickness of strips. in many mathematical models, the effect of some cold rolling parameters has been ignored and the outputs have not a desirable accuracy. in the other hand, there is a special relation among input thickness of strips, the ...

Field ion microscopy and computer simulation were used for the study of an atomic structure high-angle grain boundary in hard-drawn ultrafine-grained tungsten wire. These boundaries with special misorientations are beyond the scope of the coincident site lattice model. It was demonstrated that the special non-coincident grain boundaries are the plane-matching boundaries, and rigid-body displace...

We show that for a quantum wire with local asymmetric scattering potential the principal channels charge and heat rectification decouple renormalise differently under electron interactions, generally being more relevant. The polarisation of results from interference is tuneable through external gating. Furthermore, spin polarised or helical electrons sufficiently strong interactions regime can ...

B2223 High Temperature Superconductor (HTSC) has been prepared as a pellet by solid state reaction. Then, HTSC wires were fabricated from the prepared superconductor using powder in tube (PIT) method utilizing silver as the tube material. Superconductor powder was packed in the pure silver tube of about 4.5 mm diameter, and 50mm long. The prepared wires are of three types; with monofilament MOF...

Optimization of the wire sawing process of silicon ingots requires a profound understanding of the dynamic interaction of wire, slurry and silicon material. In this paper, the influence of wire velocity and applied wire stress on the process is investigated using dissipative particle dynamics and discrete element simulations for modelling the fluid and the grains in the abrasive suspension. In ...
