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...
We present a methodology for characterization and an approach for computing the solutions of fuzzy linear systems with LR fuzzy variables. As solutions, notions of exact and approximate solutions are considered. We transform the fuzzy linear system into a corresponding linear crisp system and a constrained least squares problem. If the corresponding crisp system is incompatible, then the fuzzy ...
in this paper, we will compare a homotopy perturbation algorithm and taylor series expansin method for a system of second kind fredholm integral equations. an application of he’s homotopy perturbation method is applied to solve the system of fredholm integral equations. taylor series expansin method reduce the system of integral equations to a linear system of ordinary differential equation.
We provide necessary and sucient conditions for psi-conditional as-ymptotic stability of the solution of a linear matrix Lyapunov system and sucientconditions for psi -conditional asymptotic stability of the solution of a rst ordernon-linear matrix Lyapunov system X0 = A(t)X + XB(t) + F(t;X).
the spline collocation method is employed to solve a system of linear and nonlinear fredholm and volterra integro-differential equations. the solutions are collocated by cubic b-spline and the integrand is approximated by the newton-cotes formula. we obtain the unique solution for linear and nonlinear system $(nn+3n)times(nn+3n)$ of integro-differential equations. this approximation reduces th...
The Linear System Analyzer (LSA) is a component-based problem-solving environment (PSE) for the manipulation and solution of large sparse linear systems of equations. Both the underlying component infrastructure and its application to the problem area of linear systems are introduced. Initial results indicate the utility of clearly separating the PSE infrastructure from the particular problem d...
abstract this study reviews the direct and indirect effects of higher energy and bread prices (due to removing their subsidies and paying their equivalent in cash instead). therefore, all consumer goods were classified into 6 groups and a linear expenditure system was estimated based on households’ budget data of 2009 and 2011 for urban and rural areas separately. the results indicate that high...
در این پایان نامه بازه ها، تعاریف ، مفاهیم اولیه و اعمال حسابی روی بازه ها را به دو صورت معمولی و اصلاح شده بیان می کنیم، سپس به تعریف بردارهای بازه ای و ماتریس های بازه ای همراه با خواص و کاربردهایشان می پردازیم، اعمال حسابی روی این گونه ماتریس ها را بیان کرده و با مفاهیمی چون دترمینان و معکوس ماتریس بازه ای آشنا می شویم. سپس به بررسی شرایط لازم و کافی برای منظم بودن ماتریس های بازه ای می پردا...
this paper studies the multi-stage supply chain system (msscm) controlled by the kanban mechanism. in the kanban system, decision making is based on the number of kanbans as well as batch sizes. a kanban mechanism is employed to assist in linking different production processes in a supply chain system in order to implement the scope of just-in-time (jit) philosophy. for a msscm, a mixed-integer...
