The basic philosophy behind creating a corporate leadership system is representation issues or the conflict of interests between the directors and shareholders. A number of mechanisms have been considered in the financial literature to reduce the problems of representation one of the outstanding mechanisms is the corporate leadership system. This paper studies the relationship between some boa...
In this paper we investigate the dilations of completely positive definite representations of (C^ast)-dynamical systems with abelian groups on Hilbert (C^ast)-modules. We show that if ((mathcal{A}, G,alpha)) is a (C^ast)-dynamical system with (G) an abelian group, then every completely positive definite covariant representation ((pi,varphi,E)) of ((mathcal{A}, G,alpha)) on a Hilbert ...
This paper proposes a Time Delay nonlinear dynamic model of HIV-1 (Human Immunodeficiency Virus type 1), introducing the drug consumption efficiencies as the controlling input for the model. The paper also represents the fuzzy T-S representation and the corresponding Fuzzy T-S controller. The controller parameters are tuned using LMIs (Linear Matrix Inequalities). The main focus is on the stabi...
A semi-analytical method is used to illustrate the behavior of a multimodal nonlinear electromechanical system which is under base-excitation. System is considered as piezo-ceramic patches attached to a cantilever beam coupled to a resistive load. The cantilever beam is modeled as a nonlinear Timoshenko beam using Assumed Mode method and equations of motion are derived through Lagrange's equati...

the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
the purpose of this study was twofold: (a) to assess the retention of two word types (synonyms and homonyms) in the short term memory, and (b) to investigate the effect of these word types on word learning by asking learners to learn their persian meanings. a total of 73 iranian language learners studying english translation participated in the study. for the first purpose, 36 freshmen from an ...
Modeling and simulation have become central to all disciplines of engineering and science. In a comprehensive modeling and simulation environment, it is desirable to integrate models specified in different modeling formalisms and to extend modeling language constructs to support multi-domain and multi-formalism modeling integrated with powerful visualization capabilities. This paper is concerne...
how crises are represented in elementary and high school textbooks through content analysis method. In the first step, the basic concepts related to this topic, were extracted from Iranian and international scientific and legal documents deductively. Then, 68 extracted concepts were put into 12 categories and were sent to the field experts in the form of a questionnaire.The reliability coeffici...
Since most current scene understanding approaches operate either on the 2D image or using a surface-based representation, they do not allow reasoning about the physical constraints within the 3D scene. Inspired by the “Blocks World” work in the 1960’s, we present a qualitative physical representation of an outdoor scene where objects have volume and mass, and relationships describe 3D structure...
