We present a general description of two mixed branes interactions. For this we consider two mixed branes with dimensions p1 and p2, in external field Bμν and arbitrary gauge fields A (1) α1 and A (2) α2 on the world volume of them, in spacetime in which some of its directions are compactified on circles with different radii. Some examples are considered to clear these general interactions. Fina...

هدف این پایان نامه ، برسی حساسیت لایه های مخلوط شونده و همراه با احتراق نسبت به دو میدان مغشوش در شرط اولیه می باشد. برای نیل به این هدف، شرط اولیه ای برای لایه های مخلوط شونده زمانی بوجود آمده است که شامل دو مدیان مغشوش برای میدان سرعت اولیه و میدان کسر مخلوط اولیه می باشد. میدان کسر مخلوط اولیه می باشد. میدان کسر مخلوط اولیه با استفاده از توابع چگالی احتمال نرمال، لگ نرمال و بتا ساخته شده و م...

The major deficiency lies in the assumption of a box model with a well-mixed boundary layer height of about 1 km, and the model calculations being constrained to measurements of OH, NO, NO2, HONO, O3, CO, CH4, C3 – C12 NMHCs. The assumption of a well-mixed boundary layer for long-lived species is appropriate, but not for shortlived (shorter than a few hours) species such as OH, NO, NO2, isopren...

The steady mixed convection boundary layer flow near the lower stagnation point of a solid sphere, generated by Newtonian heating in which the heat transfer from the surface is proportional to the local surface temperature, is considered in this study. The governing boundary layer equations are first transformed into a system of non-dimensional equations via the non-dimensional variables, and t...

In this paper linear elliptic boundary value problems of second order with non-smooth data (L∞-coefficients, Lipschitz domains, regular sets, non-homogeneous mixed boundary conditions) are considered. It is shown that such boundary value problems generate Fredholm operators between appropriate Sobolev–Campanato spaces, that the weak solutions are Hölder continuous up to the boundary and that th...

The assessment of groundwater conditions within an unconfined aquifer with a periodic boundary condition is of interest in many hydrological and environmental problems. A two-dimensional numerical model for density dependent variably saturated groundwater flow, SUTRA (Voss, C.I., 1984. SUTRA: a finite element simulation model for saturated–unsaturated, fluiddensity dependent ground-water flow w...

In this paper, the existence of solutions and extremal solutions for a second order perturbed nonlinear boundary value problem with integral boundary conditions is proved under the mixed generalized Lipschitz and Carathéodory conditions. 2000 Mathematics Subject Classification: 34A60, 34B15.

The Analog and Mixed-Signal Boundary-Scan Standard (IEEE1149.4 hereafter referred as dot4) was developed to measure external discrete components in a mixed-signal Printed Circuit Assembly (PCA). This bus uses 4 of the same signals used today to support IEEE1149.1 compliant devices and systems. It uses two additional wires bus to perform analog monitoring and control. But testing a mixed-signal ...

mixed convection of al 2 o 3 -water nanofluid in a square microcavity is investigated numerically. governing equations are discretized and solved using the finite volume method and simpler algorithm. the knudsen number is selected between 0.001 and 0.1 to consider slip velocity and the jump temperature boundary conditions. results showed that nusselt number is a function of richardson number, k...
