In ordinary transportation problems, it is always supposed that the mileage from every source to every destination is a definite number. But in special conditions, such as transporting emergency materials when natural calamity occurs or transporting military supplies during wartime, carrying network may be destroyed, mileage from some sources to some destinations are no longer definite. It is u...
در این تحقیق به بررسی و مقایسه تاثیر سازه های آبشکن نفوذپذیر و نفوذناپذیر بر مورفولوژی کف رودخانه در دو بعد پرداخته شده است. برای پیدا کردن روش حل عددی مناسب، مقایسه ای میان روش های بدون شبکه radial point interpolation method(rpim)، element free galerkin و روش اجزا محدود انجام شده است. نتیجه این تحقیق کارایی روش (rpim) را نسبت به سایر روش ها نشان می دهد. برای بدست آوردن تغییرات بستر از روش آب ه...
In this paper, the phononic structure and Enthalpy of CaB2 compound in simple hexagonal and orthorhombic phase have been investigated. The calculations were performed using the pseudo-potential method in the framework of the density functional theory and using the Quantum-Espresso code. Using the group theory and the characteristic table of the composition point group, the phonon modes were ide...
The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...
In this paper, a forward-backward projection algorithm is considered for finding zero points of the sum of two operators in Hilbert spaces. The sequence generated by algorithm converges strongly to the zero point of the sum of an $alpha$-inverse strongly monotone operator and a maximal monotone operator. We apply the result for solving the variational inequality problem, fixed po...
In this paper, we consider a proximal point algorithm for finding a common zero of a finite family of maximal monotone operators in real Hilbert spaces. Also, we give a necessary and sufficient condition for the common zero set of finite operators to be nonempty, and by showing that in this case, this iterative sequence converges strongly to the metric projection of some point onto the set of c...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
