A novel discrete singular convolution (DSC)  formulation  is  presented for the seepage analysis in irregular geometric porous media. The DSC is a new promising numerical approach which has been recently applied to solve several engineering problems. For a medium with regular geometry, realizing of the DSC for the seepage analysis is straight forward. But DSC implementation for a medium with ir...

The present paper focuses on the area of Serbian capital marked off by two transnational rivers, Sava and Danube their confluence, which determined birth development Belgrade. This area, target radical illegal urban transformations in last decade, is analysed focusing local activist groups’ engagements reactions to these dynamics. case explored a specific place Belgrade: river banks vicinity co...

We describe an efficient algorithm for coding the connectivity information of general polygon meshes. In contrast to most existing algorithms which are suitable only for triangular meshes, and pay a penalty for treatment of nontriangular faces, this algorithm codes the connectivity information in a direct manner. Our treatment of the special case of triangular meshes is shown to be equivalent t...

We present a volumetric method that can ee-ciently create triangular meshes from 3-D geometric data. This data can be presented in the form of images , prooles or unordered points. The mesh model can be created at diierent resolutions and can also be closed to make a true volumetric model.

Given a regular matrix pencil A + μE, we consider the problem of determining the nearest singular matrix pencil with respect to the Frobenius norm. We present new approaches based on the solution of matrix differential equations for determining the nearest singular pencil A+∆A+ μ(E +∆E), one approach for general singular pencils and another one such that A+∆A and E + ∆E have a common left/right...
