A superconducting wire can be considered as quasi-one dimensional (1D) if its characteristic transverse dimension is smaller than the coherence length ξ. The shape of the bottom part of the resistive transition R(T) of a not too narrow 1D strip is well described by the model of thermally activated phase slips [1,2]. However, if the wire width falls into a ~ 10 nm range, there are predictions th...

In this paper the factor of safety (FS) and critical line-segments slip surface obtained by the Alternating Variable Local Gradient (AVLG) optimization method was presented as a new topic in 2D. Results revealed that the percentage of reduction in the FS obtained by switching from a circular shape to line segments was higher with the AVLG method than other methods. The 2D-AVLG optimization meth...

Tungsten carbide cobalt hardmetals are commonly used as cutting tools subject to high operation temperature and pressures, where the mechanical performance of tungsten phase affects wear lifetime material. In this study, behaviour isolated (WC) was investigated using single crystal micropillar compression. Micropillars in two orientations, 1-5 ${\mu}$m diameter, were fabricated focused ion beam...

The hydrodynamics of immiscible micropolar fluids are important in a variety engineering problems, including biofluid dynamics arterial blood flows, pharmacodynamics, Principle Boundary layers, lubrication technology, short waves for heat-conducting fluids, sediment transportation, magnetohydrodynamics, multicomponent hydrodynamics, and electrohydrodynamic. Motivated by the development biologic...

The velocity slip of a fluid at a wall is one of the most typical phenomena in microscale gas flows. This paper presents a flow analysis considering the velocity slip in a capacitive micro gas flow sensor based on pressure difference measurements along a microchannel. The tangential momentum accommodation coefficient (TMAC) measurements of a particular channel wall in planar microchannels will ...

the majority of existing tractors in iran are not equipped with any tools to measure and display slip and ground speed. this is mainly due to the lack of national standards for measuring tools and instruments of tractors. in current research, an interchangeable system for two wheel drive tractors has been designed. furthermore, it has been assessed after construction. to measure actual and theo...
