The paper presents an improved design method of an optimal control system of a linear object with elastic coupling. The proposed method of the optimal control system design implies the selection of desired stability degree instead of the penalty matrixes selection procedure for the quadratic functional. The main idea of the method is the new state matrix utilization, which has its eigenvalues a...

the edge versions of reverse wiener indices were introduced by mahmiani et al. veryrecently. in this paper, we find their relation with ordinary (vertex) wiener index in somegraphs. also, we compute them for trees and tuc4c8(s) naotubes.

The inhibitor N-[2R-2-(hydroxamidocarbonymethyl)-4-methylpentanoyl)]-L- tryptophan methylamide specifically blocks several matrix metalloproteases, enzymes which are thought to be involved in angiogenesis. An extract of Walker 256 carcinoma in Hydron pellets implanted in the corneas of Sprague-Dawley rats was used to stimulate angiogenesis from the vessels of the limbus. Angiogenesis was graded...

This paper considers approximating a given nth-order stable transfer matrix G(s) by an rth-order stable transfer matrix Gr(s) in which n r, and where n is large. The Arnoldi process is used to generate a basis to a part of the controllability subspace associated with the realization of G(s), and a residual error is defined for any approximation in this subspace. We establish that minimizing the...
