We study motions of photons in an unmagnetized cold homogeneous plasma medium the five-dimensional charged static squashed Kaluza-Klein black hole spacetime. In this case, a photon behaves as massive particle four-dimensional spherically symmetric consider light deflection by surrounded weak-field limit. derive corrections angle to general relativity, which are related size extra dimension, cha...

We present a basic theory on Airy surface magneto plasmons (SMPs) at the interface between a dielectric layer and a metal layer (or a doped semiconductor layer) under an external static magnetic field in the Voigt configuration. It is shown that, in the paraxial approximation, the Airy SMPs can propagate along the surface without violating the nondiffracting characteristics, while the ballistic...

We have developed the variable temperature scanning force microscope capable of performing both magnetic resonance force microscopy (MRFM) and magnetic force microscopy (MFM) measurements in the temperature range between 5 and 300 K. Modular design, large scanning area, and interferometric detection of the cantilever deflection make it a sensitive, easy to operate, and reliable instrument suita...

The evolution of the crack growthspeed in a thin, buckled strip delamina-tion is studied and two approximate solu-tions are presented. The quasi-dynamicanalysis assumes that the deflection ofthe delaminated layer is represented bythe static postbuckling solution for thecurrent delamination length. A refinedanalysis introduces an indeterminateamplitude functio...

The purpose of this research is to study the mechanical behavior of a micropump with clamped circular diaphragm which is the main component of drug delivery systems. In this paper, the non-linear governing equations of the circular microplate using Kirchhoff thin plate theory was been extracted based on the modified couple stress (MCST) and classical (CT) theories. Then, the non-linear equation...

This work presents geometrically non-linear static analysis of a cantilever beam subjected to a non-follower transversal point load at the free end of the beam. The material of the beam is assumed as isotropic and hyperelastic. In this study, finite element model of the beam is constructed by using total Lagrangian finite element model of two dimensional continua for a twelve-node quadratic ele...

Journal bearing misalignment arise generally from the shaft deformation under load, deflection of the shaft, manufacturing and assembly errors, improper installation, and asymmetric loading. During operations, misalignment has a considerable effect on the static and dynamic performances. It could cause wear, vibration and even system failure. In this article, a literature review of misalignment...

In this paper, it is proposed to study the static flexural performance of hybrid (glass and steel) fiber reinforced M30 grade self-compacting concrete (SCC) beams made with glass reinforcement polymer (GFRP) re-bars. Nan Su mix design approach adopted develop plain SCC (PSCC) mixes. Glass fibre (GFRSCC), steel (GFRSCC) (HFRSCC) mixes are prepared using optimum dosages (0.05%) fibres (1%) by vol...

The paper shows an algorithm for determining the load on electric motor of run-out conveyor starting from determination first moment no operation during slab conveying, slipping torque rollers along surface conveyed billet and ending with choice motor. It also covers strength calculations roller, which includes calculation moments forces acting roller its supports, static torsion strength, defl...

It is shown that Einstein-Rosen bridges (wormholes) hypothetical objects that topologically connect separate locations in the Universe can be static solutions of the Einstein equations. The corresponding equations for bridges are reduced to a form convenient for their analysis and numerical solution. The matter forming the bridge must have a sufficiently hard and anisotropic equation of state. ...
