I consider the nonaxisymmetric linear theory of an isothermal magnetohydrodynamic (MHD) shear flow. The analysis is performed in the shearing box, a local model appropriate for a thin disk geometry. Linear perturbations in this model can be decomposed in terms of shearing waves (shwaves), which appear spatially as plane waves in a frame comoving with the shear. The time dependence of these wave...

electromagnetic forming is a high energy rate forming process in which an electromagnetic lorentz body force is used for deformation of products.  in this article, electromagnetic forming process was simulated for the assembly of parts as an innovative method.  the effect of important process parameters such as discharge energy, radius and width of rectangular groove on the strength of the asse...

In this paper, a Shearing Invariant Texture Descriptor (SITD) is proposed, which is a theoretically and computationally simple method based on the Rotation invariant Local Binary Pattern (Rot-LBP) descriptor. In real-world applications using flatbed scanners, such as paper texture fingerprinting, it’s common for a sheet of paper to rotate during the image acquisition process. Because the rotati...

The activation energies associated with the formation of a superlattice intrinsic stacking fault (SISF) from an antiphase domain boundary (APB) and the formation of a superlattice extrinsic stacking fault (SESF) from a complex stacking fault (CSF) in g 0 phase of Ni-based superalloys are calculated using a microscopic phase field dislocation model in combination with the nudged elastic band (NE...

We study the effect of spatial modulations in the interlayer hopping of graphene bilayers, such as those that arise upon shearing or twisting. We show that their single-particle physics, characterized by charge accumulation and recurrent formation of zero-energy bands as the pattern period L increases, is governed by a non-Abelian gauge potential arising in the low-energy electronic theory due ...

Local Tissue Injury In bite wounds, shearing, tensile, and compressive forces often combine to damage tissues. Little energy is transmitted to the wounded tissues in a simple shearing injury, and tissue devitalization is often minimal. Tensile forces result in avulsion of the skin from underlying tissue. Avulsion of muscles can also occur in the deeper tissue layers, resulting in hernias and mu...

According to the tedious design conditions and the difficulty to determine the optimal plan in underground foundation engineering design field at present, genetic algorithm was proposed and applied into the design of conventional reinforced concrete strip foundation. The coding method, operation procedure and penalty function of genetic algorithm were improved according to the specific issues. ...

A new computational analysis is described for estimating 3D shapes from orthographic images of surfaces that are textured with planar cut contours. For any given contour pattern, this model provides a family of possible interpretations that are all related by affine scaling and shearing transformations in depth, depending on the specific values of its free parameters that are used to compute th...
