We study duality of field theories in (d+1) dimensional flat Euclidean space and (d+1) dimensional Euclidean AdS space for both scalar the and vector fields. In the case of the scalar theory, the injective map between conformally coupled massless scalars in two spaces is reviewed. It is shown that for vector fields the injective map exists only in four dimensions. Since Euclidean AdS space is e...
In the following work we present a proof for the strong law of large numbers for pairwise negatively dependent random variables which relaxes the usual assumption of pairwise independence. Let be a double sequence of pairwise negatively dependent random variables. If for all non-negative real numbers t and , for 1 < p < 2, then we prove that (1). In addition, it also converges to 0 in ....
In this paper, to solve a linear one-dimensional Volterra integral equation of the second kind. For this purpose using the equation form, we have defined a linear transformation and by using it's conjugate and reproducing kernel functions, we obtain a basis for the functions space.Then we obtain the solution of integral equation in terms of the basis functions. The examples presented in this ...
Intrauterine Devices (IUDs) are used as an efficient and inexpensive method of contracep¬tion. Contraceptive efficacy depends on the intrauterine location of IUD and intrauterine displacement of the IUD leads to decreased contraceptive efficacy. Expulsion of IUD and its penetration into myometrium is one of the complications of IUD. In cases where IUDs are not detected by ultrasound method, in ...
ارائه راهکارهایی مناسب جهت تشخیص دقیق تر و بهتر گلوکوم مادرزادی و جلوگیری از پیشرفت آن. روش مطالعه: 50 کودک مبتلا به گلوکوم مادرزادی (گروه case) و 50کودک سالم (گروه control) در این مطالعه مورد بررسی قرار گرفتند. هر دو گروه مورد معاینه قرار گرفتند وتست پتانسیل برانگیخته از بینایی((vep روی آنها انجام شد. متغیرهای اندازه گیری شده شامل تاخیر فاز(latency) ودامنه(amplitude) بودند.نتایج ثبت و فراوا...
The object of the present paper is to study temperature distribution and thermal stresses of a functionally graded thick hollow cylinder with temperature dependent material properties. All the material properties except Poisson’s ratio are assumed to be dependent on temperature. The nonlinear heat conduction with temperature dependent thermal conductivity and specific heat capacity is reduced t...
Introduction: Dimensional changes in acrylic patterns during laboratory process to fabricate casting are an important issue which could lead to many clinical consequences. Microleakage, lack of retention and fitness are few of problems which could be predicted in the case of dimensional changes in acrylic patterns. So, investigating the factors which could minimize the dimensional change is nec...
The polynomial interpolation in one dimensional space R is an important method to approximate the functions. The Lagrange and Newton methods are two well known types of interpolations. In this work, we describe the semi inherited interpolation for approximating the values of a function. In this case, the interpolation matrix has the semi inherited LU factorization.
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
