This paper reports a study of wave motion in a generally anisotropic fractal medium (i.e. with different fractal dimensions in ifferent directions), whose constitutive response is represented by an isotropic Hooke’s law. First, the governing elastodynamic laws re formulated on the basis of dimensional regularization. It is discovered that the satisfaction of the angular momentum equation reclud...

Meshfree Collocation Method is used to solve linear two-dimensional problems. This method differs from weak form methods such as Galerkin method and no cellular networking and no numerical  integration. Therefore, this method has no constraints such as the integration accuracy and the integration CPU time, and equations can be isolated directly from the strong form of governing PDE. The fundame...

Statement of the Problem: Understanding about impression materials, their properties, uses and manipulation can guide operators towards having more successful restorations. Purpose: The aim of this in vitro study was to compare the accuracy of a condensation silicone impression material, Optosil, and an addition poly siloxane impression material, Elite-HD. Materials and Method: A laboratory mod...

This paper presents the complete algorithm of site response analysis of nonhomogeneous topographic structures using transient two-dimensional boundary element method (BEM). Seismic behaviour of various topographic features including canyon, half plane, sedimentary filled valley and ridge sections, subjected to incident SV and P waves are analysed. The analysis shows the efficiency of the propos...

Objective(s) Staphylococcus aureus is a foremost source of numerous nosocomial and community acquired infections. Antibiotic therapy for vancomycin resistant S. aureus (VRSA) can not promise the eradication of infections. Since adhesion is the major route of infections, adhesin based vaccine could suppress S. aureus infections. Fibronectin binding protein A (FnBPA) and clumping factor A (ClfA)...

In this article, a version of the frequency-domain elastodynamic Fast Multipole-Boundary Element Method (FM-BEM) for semi-infinite media, based on the half-space Green’s tensor (and hence avoiding any discretization of the planar traction-free surface), is presented. The half-space Green’s tensor is often used (in non-multipole form until now) for computing elastic wave propagation in the conte...
