Based on a precise probabilistic formulation, a spectrum superposition method has been proposed to obtain very accurate estimate of the seismic response of structures with significant contribution from high-frequency rigid modes. The proposed approach computes the exact statistics of the ordered-peaks of...
In previous studies, a two-stage optimization process was used to predict the effect of uncertainties, modeled using convex theory, on the response constraints. Here, a superposition method is used to find the response of structures with load uncertainties. The convex model is implemented on the ...
2.principle of superposition- the displacement of any point due to the superposition of wave systems is equal to the sum of the displacements of the individual waves at that point; "the principle of superposition is the basis of the wave theory of light" ...
A method for dynamic response analysis of non-linear structural systems by using the mode-superposition method is proposed. The analytical formulation is based on the solution of dynamic motion equation by the recently proposed theory of... P Cacciola,G Muscolino,A Sofi - Proceedings of SPIE -...
1) theory of superposition 重叠理论 2) Angular Overlap Model 角重叠理论 1. The d orbital energy levels in triprismatic and octahedral coordinate structures and the intermediate states between triprismatic and octahedral coordinate structures have been calculated by usingAngular Overlap Model(AOM). ...
摘要: The notion of product is introduced in the framework of proposition-state structures. Central roles are played by the invariance of the superposition relation and the maximality property of the states under the interaction of physical systems....
We propose an additive "semantic measure" theory based on the model of a perception based fuzzy truthoods in analogy to probability measure. Probability measure, which is the subject of the probability theory, is a special case of the fu... IB Türksen,G Resconi - 《International Journal ...

We characterize all pairs of entire functions (u,ψ) for which the induced weighted superposition operator S(u,ψ) transforms one Fock space into another Fock space. Further analytical structures like boundedness and Lipschitz continuity of S(u,ψ) are described. We, in particular, show the Foc...
The superposition approximation is a mathematical device of restricting the coupling between particle groupings in a way that makes the formulae of the theory tractable in calculations; From: An Introduction to the Statistical Theory of Classical Simple Dense Fluids, 1967 ...
