Abstract In this paper, we compute the band structure of one- and two-dimensional phononic composites using extended finite element method (X-FEM) on structured higher-order (spectral) meshes. On partition-of-unity enrichment in analysis, X-FEM permits use meshes that do not conform to geometry holes inclusions. This eliminates need for remeshing shape optimization topology studies. two dimensi...

background: every year many organizations formulate a code of ethics (coe) but when it comes to implementing, it does not achieve the desired purposes. ineffectiveness of coes can stem from different factors and surely, one of them is bad formulation. this research was conducted to identify the barriers to effective formulation of coes in one of the main state universities of medical sciences i...

This work demonstrates in practical terms the evolutionary concepts and computational applications of Parametric Curves. Specific cases were drawn from higher order parametric Bezier curves degrees 2 above. find real life diverse areas Engineering Computer Science, such as computer graphics, robotics, animations, virtual reality, among others. Some issues explored this are equations derivations...

The scope of this paper is to look at some aspects the differential geometry Bezier curves in Minkowski space. For that purpose, we firstly introduce Frenet curve 3-space. Especially, investigate Serret-Frenet frame, curvature and torsion all points. Moreover, give apparatus these end
