The SST decomposition method for solving system of linear equations make it possible to obtain the values of roots of the system with the specified accuracy as the limit of the sequence of some vectors. In this topic we are going to consider vectors as fuzzy vectors. We have considered a numerical example and tried to find out solution vector x in fuzzified form using method of SST decomposition.

where u is the displacement and f 2 L( ) is the body force. Some of the simplest plate elements such as the Morley element (cf. [29]), the Zienkiewicz element (cf. [3]), the Fraeijs de Veubeke element (cf. [22]), the incomplete biquadratic element (cf. [34]) and the Adini element (cf. [1]) are nonconforming. Overlapping domain decomposition methods for nonconforming plate elements were studied ...

Hypertree-decomposition is the most general approach in the literature for identifying tractable computation problems encoded as hypergraphs. We show how the heuristic branch-decomposition approach for ordinary graphs of [Cook and Seymour, 2003] can be used for the heuristic construction of hypertree-decompositions.

More recently, Wazwaz [An analytic study of Fisher’s equation by using Adomian decomposition method, Appl. Math. Comput. 154 (2004) 609–620] employed the Adomian decomposition method (ADM) to obtain exact solutions to Fisher’s equation and to a nonlinear diffusion equation of the Fisher type. In this paper, He’s homotopy perturbation method is employed for the generalized Fisher’s equation to o...

A convergence theory is presented for a substructuring preconditioner based on constrained energy minimization concepts. The preconditioner is formulated as an Additive Schwarz method and analyzed by building on existing results for Balancing Domain Decomposition. The main result is a bound on the condition number based on inequalities involving the matrices of the preconditioner. Estimates of ...
