A new procedure for calculating eld points with the boundary element method (BEM) is outlined. In the conventional BEM (CBEM) eld points are computed as post{processing by recurrently solving the boundary integral equation with known boundary data for every eld point of interest. This procedure is very time-consuming. On the other hand, newly developed hybrid boundary element formulations (HBEM...

Bordered almost block diagonal systems arise from discretizing a linearized rst-order system of n ordinary diierential equations in a two-point boundary value problem with non-separated boundary conditions. The discretization may use spline collocation, nite diierences, or multiple shooting. After internal condensation, if necessary, the bordered almost block diagonal system reduces to a standa...

This paper proposes a color decomposition method for a multi-primary display (MPD) using a 3-dimensional look-uptable (3D-LUT) in linearized LAB space. The proposed method decomposes the conventional three primary colors into multi-primary control values for a display device under the constraints of tristimulus matching. To reproduce images on an MPD, the color signals are estimated from a devi...

A method is developed for the computation of the weights and nodes of a numerical quadrature which integrates functions containing singularities up to order 1/x2, without the requirement to know the coefficients of the singularities exactly. The work is motivated by the need to evaluate such integrals on boundary elements in potential problems and is a simplification of a previously published m...

Design of a 1200 kV power transformer is a real challenge for designer from dielectric point of view. It is possible to design a more compact transformer meeting even higher insulation levels with lesser insulation content. This has been possible with the introduction of sophisticated Computer-Aided Electrostatic Field Analysis. Analysis of the Lead Exit assembly of 1200 kV HV is presented. Two...

We consider timelike Liouville theory with FZZT-like boundary conditions. The bulk one-point and two-point structure constants on a disk are derived using bootstrap techniques. find that these not the analytic continuations of their spacelike counterparts.

In this paper, a spectral collocation approach based on the rational Chebyshev functions for solving the axisymmetric stagnation point flow on an infinite stationary circular cylinder is suggested. The Navier-Stokes equations which govern the flow, are changed to a boundary value problem with a semi-infinite domain and a third-order nonlinear ordinary differential equation by applying proper si...

In this paper, we propose a method for creating a threedimensional polygonal model reflecting precise boundary of physical objects from a point cloud which has strong anisotropic distribution of points obtained by a mobile mapping system. Our method creates boundary information of physical objects based on the planar region segmentation by the line-based region growing approach from a point clo...

In this paper an exponentially fitted finite difference method is presented for solving singularly perturbed two-point boundary value problems with the boundary layer. A fitting factor is introduced and the model equation is discretized by a finite difference scheme on an uniform mesh. Thomas algorithm is used to solve the tri-diagonal system. The stability of the algorithm is investigated. It ...
