In this paper we propose an extension to the work of Lischinski et al [1] on combining hierarchical radiosity method and discontinuity meshing. The extension proposed here supports higher order radiosity function at the es timation s tep itself. We have carried out this extension using M ultiWavelet basis function s. Unlike th e multi-wavelet radiosity work of Gortler et al [2] which uses reg u...

AIM Analysis of indications for stapes revision surgery in patients qualified for the secondary procedure at the Otosurgery Dept. Medical University of Lodz. MATERIAL AND METHODS 25 cases of stapes revision surgery out of the 385 total treated surgically otosclerosis cases are discussed. RESULTS In group A (patients after total stapedectomy) the following indications for the secondary surgi...

Linear elastic boundary element models are commonly used tools to understand the mechanics of earthquake cycle processes and their contribution growth tectonic structures. Here we describe a two-dimensional plane strain linear approach based on displacement discontinuity method. This integrates an analytic solution for coincident interactions using three node quadratic elements classic particul...

free surface sloshing of liquid in a rectangular tank induced by lateral excitation has been studied numericallyand experimentally in this paper. the numerical simulation is carried out based on the volume of fluid (vof) method that provides free surface extraction in such problem. a tank with transparent walls is used to free surface tracking in experimental study while the movement amplitude ...

We consider the zero heat conductivity limit to a contact discontinuity for the mono-dimensional full compressible Navier-Stokes-Fourier system. The method is based on the relative entropy method, and do not assume any smallness conditions on the discontinuity, nor on the BV norm of the initial data. It is proved that for any viscosity ν ≥ 0, the solution of the compressible Navier-Stokes-Fouri...

The solutions of the perturbed Riemann problem for the chromatography system of Langmuir isotherm with one inert component are constructed in completely explicit forms when the initial data are taken as three piecewise constant states. The wave interaction problem is investigated in detail by using the method of characteristics. In addition, the generalized Riemann problem with the delta-type i...

Numerical simulation of two-phase flow with imbedded interface of discontinuity is challenging in two major aspects. First, the interface can undergo change, merge and breakup during the course of the simulation. Examples of current successful methods in modeling flow with interface are, among others, the volume-of-fluid method, fronttracking method, and level-set method. Second, flow variables...
