diffusivity equation commonly used for pressure distribution prediction in porous media results from substituting equation of state and continuity equation in navier-stokes momentum equation. from mathematical point of view this equation format shows infinite propagation speed for pressure pulse through porous media, which is physically impossible. this issue may caused by numerous assumptions ...
In this paper, we intend to solve special kind of ordinary differential equations which is called Heun equations, by converting to a corresponding stochastic differential equation(S.D.E.). So, we construct a stochastic linear equation system from this equation which its solution is based on computing fundamental matrix of this system and then, this S.D.E. is solved by numerically methods. Moreo...
چکیده: آنچه که در این تحقیق به آن پرداخته خواهد شد ، حل معادلاتِ دینامیکِ سیالات هادی جریان الکتریکی(mhd equation) برروی استوانه ای از جنس غشای نفوذپذیر، در حضور میدان مغناطیسی همراه با انتقال جرم می باشد.پس معادلات انتقال جرم و (mhd) را در مختصات استوانه ای استخراج کرده و حل تشابهی برای آنها انجام می دهیم. برای استخراج و حل معادلات مذکور فیزیک مساله را درنظر می گیریم ، که استوانه ای است از جنس ...
Background: Domestic violence, including child abuse, spousal elder and parent is a common issue in the modern world. Parent abuse one of phenomena that has been focus attention recent decades due to its negative effects on family system. Objectives: This study aimed investigate predictors boy students. Methods: present was correlational study. The statistical population all second-grade high s...
won{gil park [won{gil park, j. math. anal. appl., 376 (1) (2011) 193{202] proved the hyers{ulam stability of the cauchy functional equation, the jensen functional equation and the quadraticfunctional equation in 2{banach spaces. one can easily see that all results of this paper are incorrect.hence the control functions in all theorems of this paper are not correct. in this paper, we correctthes...

Rubber (Hevea brasiliensis) plantations have high water consumption through evapotranspiration, which can contribute to scarcity. In addition, there is a lack of spatial observation data and estimation methods for evapotranspiration (ET) rubber plantations. To alleviate the stress expanding caused by seasonal drought in Xishuangbanna, Southwest China, an up 7 days crop (ETc) forecast method, “K...
