In the present work, a study of thermoelastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient and non-uniform internal pressure is carried out. The formulation is based on first-order shear deformation theory (FSDT), which accounts for the transverse shear. The governing equations, derived using minimum total potential energy principle, are solved, usi...

Abstract We consider Prandtl’s boundary layer problem for incompressible laminar flow past a three dimensional yawed wedge. When the Reynolds number is large the solution of this problem has a parabolic boundary layer. We construct a direct numerical method for computing approximations to the solution of this problem using a compound piecewise-uniform mesh appropriately fitted to the parabolic ...

Parameterizations of triangulated surfaces are used in an increasing number of mesh processing applications for various purposes. Although demands vary, they are often required to preserve the surface metric and thus minimize angle, area and length deformation. However, most of the existing techniques primarily target at angle preservation while disregarding global area deformation. In this pap...

_ One of the main assumptions in the Clarke’s classic channel model is isotropic scattering, i.e. uniform distribution for the angle of arrival of multipath components at the mobile station. However, in many mobile radio channels we encounter non-isotropic scattering, which strongly affects the correlation function and power spectrum of the complex envelope at the mobile receiver. In this contr...

The microstructures of copper chips created by plane strain machining at ambient temperature have been analyzed using transmission electron microscopy (TEM) and orientation imaging microscopy (OIM). The strain imposed in the chips was varied by changing the tool rake angle. Characterization of orthogonal faces of the chips showed the microstructure to be essentially uniform through the chip vol...

The notion of uniform interpolation for description logic ALC has been introduced in [9]. In this paper, we reformulate the uniform interpolation for ALC from the angle of forgetting and show that it satisfies all desired properties of forgetting. Then we introduce an algorithm for computing the result of forgetting in concept descriptions. We present a detailed proof for the correctness of our...

A class of exact mathematical solutions describing distributed regions of uniform vorticity attached to two solid walls meeting at an angle 2α is derived. Exterior to the uniform vorticity region the flow is quiescent and irrotational. The mathematical method used is a generalization of ideas original presented in Crowdy [4] combined with elements of conformal mapping theory associated with a d...

Uniform wall thickness plays an essential role in avoiding forming failure incremental sheet forming. However, it is challenging to promote the uniform distribution of single-pass high angle and complex three-dimensional thin-walled parts using flexible dieless technology. In this article, based on hydraulic support single-point technology, finite element software used simulate analyze influenc...

Discrete bends in the propagation direction of plane TEM waves can be achieved utilizing the Brewster angle at a planar interface between media of different uniform isotropic pennittivities. This paper extenda this to cases of multiple dielectric or nonuniform permittivity. The nonuniform case is a generali~tion of the Brewster-angle concept. This is also related to special log-spiral solutions...
