A point particle approximation to the classical dynamics of well separated vortices of the abelian Higgs model is developed. The asymptotic static intervortex potential is calculated and used to model type II vortex scattering. A velocity dependent interaction Lagrangian for critically coupled vortices is derived, and reinterpreted geometrically to obtain a conjecture for the asymptotic form of...

We report calculated elastic differential cross sections for electronscattering by H 2 0 at 15, 20 and 30 eV, using the iterative Schwinger variational method in a fixed-nuclei static-exchange approximation. Our results compare very favorably with recent experimental and theoretical ~esu l t s at a11 angles above 30 degrees. Nevertheless, as used here, this approximation can xiot describe corre...

We present a new method for accelerating the rendering of complex static scenes. The technique is applicable to unstructured scenes containing arbitrary geometric primitives and has sublinear asymptotic complexity. Our approach is to construct a spatial hierarchy of cells over the scene and to associate with each cell a simplified representation of its contents. The scene is then rendered using...

In this paper, we propose a new object classification technique based on polygonal approximation of the open profile of object. The vertices of polygonal approximation are formed by high curvature points of the profile and they are selected by Fourier transform of the object contour. A series of features are computed from the polygonal approximation and then the minimum distance classifier is u...

In this study, the missile staging process by implementing a side-injected jet is simulated numerically. The problem is considered to be axisymmetric and the thin shear layer approximation of Navier-Stokes equations along with an algebraic turbulence model is used in a quasi-static form for the calculations. The free stream corresponds to a very high altitude flight condition with a Mach number...

We introduce new discretizations of the action for static quarks. They achieve an exponential improvement (compared to the Eichten-Hill regularization) on the signal to noise ratio in static–light correlation functions. This is explicitly checked in a quenched simulation and it is understood quantitatively in terms of the self energy of a static quark and the lattice heavy quark potential at ze...

In this study, static and free vibration analyses of functionally graded (FG) nanocomposite plates, reinforced by wavy single-walled carbon nanotubes (SWCNTs) resting on a Pasternak elastic foundation, were investigated based on a mesh-free method and modified first-order shear deformation theory (FSDT). Three linear types of FG nanocomposite plate distributions and a uniform distribution of wa...

In this paper static analysis of orthotropic functionally graded material (FGM) cylinders with finite length was carried out by a mesh-free method. MLS shape functions are used for approximation of displacement field in the weak form of equilibrium equation and essential boundary conditions are imposed by transformation method. In this simulation, an ax symmetric model is used. Mechanical prope...

In this paper, the temperature dependence on optical absorption cross section of the core shell bimetallic nanoparticles (NPs) is investigated in quasi static approximation. Temperature dependence of the plasmon resonance is important issue because of recent applications of NPs of noble metal for heat treating of cancer and the computer chips. The effect of temperature on surface plasmon resona...
