the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
نامساوی ها یکی از مهمترین حوزه های پژوهشی آنالیز ماتریسی هستند که از ابتدا مورد علاقه بسیاری از ریاضی دانان بوده و کاربردهایی در علوم مختلف از جمله محاسبات علمی، نظریه سیستم و کنترل، تحقیق در عملیات، فیزیک ریاضی، استاتیک، اقتصاد و مهندسی دارد. نخستین بار در سال $1934$ کتاب تقریبا جامعی با نام "نامساوی ها" cite{h} توسط هاردی، ltrfootnote{g. h. hardy} لیتل وود ltrfootnote{e. little...
برگروه لی$ g=so_{0}(n,1) $، یک متریک ناوردای چپ تعریف می شود که از فرم کیلینگ-کارتان بدست می آید. زیرگروه فشرده همبند بیشین آن عبارت است از $ so(n)=so(n) imeslbrace 1 brace $که با$ k $ نمایش می دهیم.گروه طولپایی های$ g $ عبارت است از egin{equation*} isom_{0}(g)=g imes k, end{equation*} یعنی ضرب چپ توسط عضو های$ g $ و ضرب راست توسط عضو های $ k $. بنابراین، دو عمل برای $ k...
This article is concerned with a conjecture in [B. Dubrovin, Comm. Math. Phys., 267 (2006), pp. 117–139] on the formation of dispersive shocks in a class of Hamiltonian dispersive regularizations of the quasi-linear transport equation. The regularizations are characterized by two arbitrary functions of one variable, where the condition of integrability implies that one of these functions must n...
The aim of this study is to investigate the characteristics gas-non-Newtonian liquids flow patterns in square microchannels. microchannels that used was made by acrylic material with horizontal orientation and side length 8x10-4 m. Water, Air, Carboxymethyl Cellulose 0.2%wt (CMC 0.2%wt) aquoeus solution, Xanthan Gum (XG solution were as liquid test. Moreover, nitrogen gas superficial velocity v...
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...
