This paper considers large discrete-time linear systems obtained from discretized partial differential equations, and controlled by a quantized law, i.e., a piecewise constant time function taking a finite set of values. We show how to generate the control by, first, applying model reduction to the original system, then using a “state-space bisection” method for synthesizing a control at the re...

Dr. Morris Karnovsky is the 1990 recipient of the E. B. Wilson Award, the highest honorbestowed by the American Society of Cell Biology. Dr. Karnovsky is so honored for his numerous fundamental and seminal discoveries on cell structure and function relationships that have farreaching interdisciplinary impact on cell biology, in physiology, and in pathology. Morris was born in South Africa. He r...

Text and context are two essential elements in human communication. Text can not exist in a vacuum. Its production and comprehension are influenced and restricted by context. This paper aims to analyze the relations between context and text with the framework of both traditional context and cognitive context by Sperber & Wilson.

The Wilson-Cowan model describes the evolution of excitatory and inhibitory activity in a synaptically coupled neuronal network. As opposed to being a detailed biophysical model, the system is a coarse-grained description of the overall activity of a large-scale neuronal network, employing just two differential equations. Key parameters in the model are the strength of connectivity between each...

We show that the supersymmetric Wilson loops in IIB matrix model give a transition from supersymmetric Yang-Mills theory to supersymmetric space-time theory. In comparison with Green-Schwarz superstring we identify the supersymmetric Wilson loops with the asymptotic states of IIB superstring. It is pointed out that the supersymmetry transformation law of the Wilson loops is the inverse of that ...

A new theoretical model based on the local composition concept (TNRF-mNRTL model) was proposed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. This contribution of interaction along with the long-range contribution of interaction (Pitzer-Debye-Hückel equation), configurational entropy of mixing (Flory-Huggins relation)...

We consider the question of gauge invariance of the Wilson loop in the light of a new treatment of axial gauge propagator proposed recently based on a finite field-dependent BRS (FFBRS) transformation. We remark that as under the FFBRS transformation the vacuum expectation value of a gauge invariant observable remains unchanged, our prescription automatically satisfies the Wilson loop criterion...

in this research, performance of pattern search algorithm (ps) was investigated in order to optimize the nonlinear muskingum model parameters in contrast with the general algorithms, for wilson and karoun floods routing. wilson flood routing has been chosen to compare the ability of ps algorithm with other algorithms and, karoun flood routing has been chosen for a better evaluation of ps. the r...
