according to heidegger human existence is not encapsulated and limited in itself, rather it is a transcendental existence which is standing out in the world. this ecstasy is rooted in the deeper relation between human existence and being. in heidegger philosophy this necessary relation between man and world is an essential element in the existential structure of man. that is why he uses the ter...

Abstract The aim of this study is to develop coupled matrix formulations characterize the dynamic interaction between vehicle, track, and tunnel. vehicle–track system established in light dynamics theory. physical characteristics mechanical behavior tunnel segments rings are modeled by finite element method, while soil layers vehicle–track–tunnel (VTT) as an assemblage 3-D mapping infinite elem...

A MAD (maximal almost disjoint) family is an infinite subset A of the infinite subsets of ω = {0, 1, 2, . . . , } such that any two elements of A intersect in a finite set and every infinite subset of ω meets some element of A in an infinite set. A Q-set is an uncountable set of reals such that every subset is a relative Gδ set. It is shown that it is relatively consistent with ZFC that there e...

In typical Lamb wave simulation practices, effects of plate edge reflections are often not considered in order to simplify the wave signal interpretations. Methods that are based on infinite plates such as the semi-analytical finite element method is effective in simulating Lamb waves as it excludes the effect of plate edges. However, the inclusion of plate edges in a finite plate could render ...

An efficient and highly accurate, Symmetric Galerkin Boundary Element Method Finite Element Method based alternating method, for the analysis of three-dimensional non-planar cracks, and their growth, in structural components of complicated geometries, is proposed. The crack is modeled by the symmetric Galerkin boundary element method, as a distribution of displacement discontinuities, as if in ...
