We consider the problem of simultaneous nite gain L p-stabilization and internal stabilization of linear systems subject to input saturation via linear static state feedback. We show that bounded input nite-gain L p-stabilization and local asymptotic stabilization can always be achieved simultaneously no matter where the poles of the open loop system are, and the locations of these poles play a...

We use a local energy method to study the spatial localization of the supports of the solutions of a reaction{ diiusion system with nonlinear diiusion and a general reaction term. We establish nite speed of propagation and the existence of waiting times under a set of weak assumptions on the structural form of the system. These assumptions allow for additive and multiplicative reaction terms an...

in this paper we introduce a sequential block iterative method and its simultaneous version with op-timal combination of weights (instead of convex combination) for solving convex feasibility problems.when the intersection of the given family of convex sets is nonempty, it is shown that any sequencegenerated by the given algorithms converges to a feasible point. additionally for linear feasibil...

most developing countries have achieved productivity growth in economic sectors like agriculture for more than 30 years. universities and governmental research centers have tried to generate knowledge with direct social and economic effects during these decades. so, productivity and production growth can be attributed to technological changes made possible through investment in agricultural res...

The present article investigates effects of the multi-frequency excitation on the output power of a piezomagnetoelastic energy harvester. The piezomagnetoelastic power generator is assumed to operate in the mono-stable mode. A perturbation technique based on the method of multiple scales is employed to develop an analytical solution to nonlinear differential equations governing the system dynam...

The control function approach (Heckman and Robb (1985)) in a system of linear simultaneous equations provides a convenient procedure to estimate one of the functions in the system using reduced form residuals from the other functions as additional regressors. The conditions on the structural system under which this procedure can be used in nonlinear and nonparametric simultaneous equations has ...

In this paper, we propose a framework to systematically analyze the structural form and thematic content of codes of ethics related to Information and Communication Technology (ICT codes of ethics). Then we apply this framework, within a sample of 30 organizations. Our purpose is to assess the organizational ethical positioning advocated by these ICT codes of ethics, using an adaptation of Kohl...

Understanding the inherent structure of manipulative hand movements is a critical step toward automatic recognition of manipulative hand movements and toward automatic planning of natural movements for dexterous robots. Manipulative hand movements involve coordinated movements of the digits to manipulate an object within the hand, and are classified as either simultaneous or sequential. Simulta...

We report on a long-term monitoring campaign of 1E 1841−045, the 12-s anomalous X-ray pulsar and magnetar candidate at the center of the supernova remnant Kes73. We have obtained approximately monthly observations of the pulsar with the Rossi X-ray Timing Explorer (RXTE) spanning over two years, during which time 1E 1841−045 is found to be rotating with sufficient stability to derive a phase-co...

This paper focuses on the implementation of a novel semantic-based Conversational Agent (CA) framework. Traditional CAs interpret scripts consisting of structural patterns of sentences. User input is matched against such patterns and an associated response is sent as output. This traditional CA approach, which solely takes into account the structural form of a sentence, requires the scripter to...
