Combining the multilevel fast multipole method with the uniform geometrical theory of diffraction

Combining the Ultra-Weak Variational Formulation and the Multilevel Fast Multipole Method

Because of its practical significance, many different methods have been developed for the solution of the time-harmonic Maxwell equations in an exterior domain at higher frequency. Often methods with complimentary strengths can be combined to obtain an even better method. In this paper we provide a numerical study of a method for coupling of the Ultra-Weak Variational Formulation (UWVF) of Maxw...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Algorithm of Diffraction for Standing Tree based on the Uniform Geometrical Theory of Diffraction

Manuscript received September 11, 2011 * Corresponding author; E-mail: [email protected] Abstract— The diffraction fields and the shadow of standing tree diffraction are solved by using polygons to approximately take the place and approximation as approximate substitutes of for the circle. The algorithm model of ray path tracing is computed by tracing the ray path on standing tree. Considering el...

The Inverse Fast Multipole Method

This article introduces a new fast direct solver for linear systems arising out of wide range of applications, integral equations, multivariate statistics, radial basis interpolation, etc., to name a few. The highlight of this new fast direct solver is that the solver scales linearly in the number of unknowns in all dimensions. The solver, termed as Inverse Fast Multipole Method (abbreviated as...
