An adaptive direct variational grid generation method

Hartley Series Direct Method for Variational Problems

The computational method based on using the operational matrix of anorthogonal function for solving variational problems is computeroriented. In this approach, a truncated Hartley series together withthe operational matrix of integration and integration of the crossproduct of two cas vectors are used for finding the solution ofvariational problems. Two illustrative...

Equidistribution Method For Adaptive Grid Generation

The equidistribution method for constructing the mo tionless regular grids is considered in the present paper. The grids are adapted to the curvilinear boundaries of the domain and to the control function, which is a priori giv en in the domain. Using the general methodology, which is based on the equdistr ibution principle, the nonlinear equations of elliptic type are obtained for the definiti...

RBF-Chebychev direct method for solving variational problems

This paper establishes a direct method for solving variational problems via a set of Radial basis functions (RBFs) with Gauss-Chebyshev collocation centers. The method consist of reducing a variational problem into a mathematical programming problem. The authors use some optimization techniques to solve the reduced problem. Accuracy and stability of the multiquadric, Gaussian and inverse multiq...

An Adaptive Scheduling Method for Grid Computing

By enlarging Grid, there is a requirement to use some new methods in order to manage it in various issues. One of the essential issues in the management of resources is scheduling. With regards to the dynamism and vast size of Grid, there is a need to adapt scheduling to surroundings and assign acts to resources so as to increase the efficiency and do jobs at an acceptable time. A method which ...
