This study is concerned with the formulation of three dimensional mapped infinite elements with 1/r and 1/ decay types. These infinite elements are coupled with conventional finite elements and their application to some problems of soil structure interaction are discussed. The effeciency of the coupled finite-infinite elements formulation with respect to computational effort, data preparation a...
Linear stability analysis of the three dimensional plane wake flow is performed using a mapped finite di?erence scheme in a domain which is doubly infinite in the cross–stream direction of wake flow. The physical domain in cross–stream direction is mapped to the computational domain using a cotangent mapping of the form y = ?cot(??). The Squire transformation [2], proposed by Squire, is also us...
In this paper a general analytical solution is obtained to find stress distribution in a finite elastic plate with a circular or square hole subjected to arbitrary biaxial partial loading using modified boundary condition by assuming plane stress conditions. The method employed is based on solution of circular hole in finite rectangular plate. This plate is mapped to circular ones and the parti...
In modern design ows low power aspects should be considered as early as possible to minimize power dissipation in the resulting circuit. A new BDD-based design style that considers switching activity optimization using temporal correlation information is presented. The technique is developed as an approximation method for switching activity estimation. Experimental results on a set of MCNC and ...
We present an approach for constructing finite-volume methods of any order of accuracy for control-volume discretizations of space defined as the image of a smooth mapping from a rectangular discretization of an abstract coordinate space. Our approach is based on two ideas. The first is that of using higher-order quadrature rules to compute the flux averages over faces that generalize a method ...
ParMooN is a program package for the numerical solution of elliptic and parabolic partial differential equations. It inherits the distinct features of its predecessor MooNMD [28]: strict decoupling of geometry and finite element spaces, implementation of mapped finite elements as their definition can be found in textbooks, and a geometric multigrid preconditioner with the option to use differen...
Conventional asynchronous control circuit design is complex because potential designs must be analysed for the existence of hazards and state variable races, as these may cause incorrect circuit operation. We present the innovative CMOS direct-mapped asynchronous circuit design approach, which, by defining a one-to-one mapping between state diagram and CMOS circuit implementation, removes the n...
