Differential quadrature solution of heat- and mass-transfer equations

existence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی ‎‏بیان شد‎‎‏ه اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

Numerical Solution of Inverse Heat Transfer Problems by Parameters Estimation of Ordinary Differential Equations

In this paper, algorithms for solving of two inverse onedimensional heat transfer problems are considered. They are: the coe cient inverse problem and the determination of phase interface location in a melting problem. These inverse problems are reduced to parameters estimation of ordinary di erential equations (ODE) using a nite element method. The algorithm based on the sensitivity analysis i...

Approximate Solution of Fuzzy Fractional Differential Equations

‎In this paper we propose a method for computing approximations of solution of fuzzy fractional differential equations using fuzzy variational iteration method. Defining a fuzzy fractional derivative, we verify the utility of the method through two illustrative ‎examples.‎
