for dynamic analyses of railway track structures, the algorithm of solution is very important. for estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. for studying the effects of axially beam on the ela...

resorption of tooth structures can occur as a result of physiological, pathological, and idiopathic factors. early diagnosis and appropriate treatment can prevent its serious complications. this case report presents surgical endodontic management of a trauma-induced perforating external root resorption, which was diagnosed with the help of cone beam computed tomography. following root canal tre...

A new proof of Friedrich’s theorem on the existence and stability of asymptotically de Sitter spaces in 3+1 dimensions is given, which extends to all even dimensions. In addition we characterize the possible limits of spaces which are globally asymptotically de Sitter, to the past and future.

Using the Chern-Simon formulation of (2+1) gravity, we derive, for the general asymptotic metrics given by the Fefferman-Graham-Lee theorems, the emergence of the Liouville mode associated to the boundary degrees of freedom of (2+1) dimensional anti de Sitter geometries.

Measurements and simulations of liquid-crystal devices with InPlane Switching structures are compared. It is shown that the Jones calculus breaks down in case of rapid lateral variations in the director profile. Advanced simulation methods like the reduced-order grating method and the beam propagation method, which take into account diffraction effects, show good agreement with experiment.

Additively manufactured polymer parts are often designed like composite sandwich structures. In this work, beam-like specimens with hexagonal, triangular and rectangular infills were different infill densities. An influence of the shape on overall stiffness was observed. The bending hexagonal between 13% 25% lower than that other two cases instead showed similar performances. Numerical simulati...

A large variety of spacetimes|including the BTZ black holes|can be obtained by identifying points in 2+1 dimensional anti-de Sitter space by means of a discrete group of isometries. We consider all such spacetimes that can be obtained under a restriction to time symmetric initial data and one asymptotic region only. The resulting spacetimes are non-eternal black holes with collapsing wormhole t...

We construct a model of gravity in 1+1 spacetime dimensions in which the solutions approach the Schwarzschild metric at large r and de Sitter space far inside the horizon. Our model may be viewed as a two dimensional application of the 'Limiting Curvature Construction' of reference[6].
