In this paper, by use of equivalence operators δ_i and semi-equivalence operators ε_i we study the clustering problems of complex systems, present δ_i(1,3) d
Two basic hypothesises of Taylor-Galerkin Finite Element Method are studied in this paper.One of them which is unreasonable is redefined.The only hypothesis bec
In this paper we introduce a new class of generalized complementarity problems for the fuzzy mappings and construct a new iterative algorithm. We also discuss t
A method of determining bifurcation directions at a double eigenvalue is presented by combining the finite element method with the perturbation method. By using
This paper builds symmetrically general theories of rods and shells under mathematical frame of "Hilbert Space", and successfully obtains the error estimate to
In this paper, the axisymmetric problems of arbitrary thick spherical shell and solid sphere are studied directly from equilibrium equations of three-dimensiona
