In this paper, we propose a new family of probability laws based on the Generalized Beta Prime distribution to evaluate relative accuracy between two Lagrange finite elements Pk1 and Pk2,(k1<k2). Usually, element is comparison asymptotic speed convergence, when mesh size h goes zero. The here highlight that there exists, depending h, cases where more likely accurate than Pk2 element. To conf...

This paper investigates the effects of mutual coupling between the elements of an array on direct data domain algorithms. Mutual coupling severely undermines the interference suppression capabilities of direct data domain algorithms. The method of moments (MoM) is used to evaluate the mutual coupling between the elements of a given array. The MoM admittance matrix is then used to eliminate the ...

Orthogonal eigenstructure control is a novel control method that recently has been developed by the authors as a method for active vibration cancellation. This method is a feedback control method, which is applicable to linear multi-input multi-output systems. The remarkable advantage of this method over most of the eigenstructure assignment methods is that it neither needs pole placement nor e...

The Trojan-Horse method is an indirect approach to determine the energy dependence of S factors of astrophysically relevant two-body reactions. This is accomplished by studying closely related three-body reactions under quasi-free scattering conditions. The basic theory of the Trojan-Horse method is developed starting from a post-form distorted wave Born approximation of the T-matrix element. I...

in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of  jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...

solving a large sparse set of linear equations is of the problems widely seen in every numerical investigation in the entire range of engineering disciplines. employing a finite element approach in solving partial derivative equations, the resulting stiffness matrices would contain many zero-valued elements. moreover, storing all these sparse matrices in a computer memory would slower the compu...

The results are algebraic structure positive or zero part symmetrization is a semi-field, can be viewed as in context Furthermore, form result subtraction elements symmetrization, multiplicative inverse element non zero-positive negative part, balance an analogy to similarity linear also obtai...

A three-dimensional finite element implementation of a simple nonassociative Drucker-Prager plasticity model with strong discontinuity mode of localized deformation is formulated for small deformations. A strong discontinuity mode of localized deformation represents slip along a surface of zero measure, whereas a weak discontinuity mode of localized deformation represents shear within a band of...

A novel blind DS-CDMA array channel estimator is presented which is capable of handling severe frequency-selective channels, where the multipath delay spread can be comparable with the data symbol period. By employing the concept of the spatiotemporal array (STAR) manifold, a subspace-type estimation algorithm is proposed, in conjunction with an onedimensional temporal smoothing procedure, to j...
