A Generic Performance Analysis Technique Applied to Different CFD Methods for HPC

A particle accelerated CFD-BEM technique applied to aeroacoustic scattering

A particle accelerated computational fluid dynamics (CFD) boundary element method (BEM) technique is proposed that allows the total sound pressure field produced by low Mach number flow past a rigid body to be predicted. An incompressible CFD solver is used to calculate the transient hydrodynamic flow field. The CFD/BEM coupling technique is then used to compute the acoustic pressure and pressu...

Sweep as a Generic Pruning Technique Applied to Constraint Relaxation

We introduce a new generic filtering algorithm for handling constraint relaxation within constraint programming. More precisely, we first present a generic pruning technique which is useful for a special case of the cardinality operator where all the constraints have at least two variables in common. This method is based on a generalization of a sweep algorithm which handles a conjunction of co...

CFD-Based Optimization Methods Applied to Polymer Die Design

The integration of optimization algorithms with computational fluid dynamics (CFD) is becoming more practical as the software becomes more robust and the hardware more efficient. In order to investigate the application of CFD-based optimization methods in the chemical process industry, two polymer die design examples were explored using different slot die geometries, different CFD codes, and di...

Generic Texture Analysis Applied to Newspaper SegmentationPaul

This paper deals with the segmentation of grey-scale newspaper images into the distinct regions of text, picture and background. Feature vectors are obtained from the image by analysing localised textual characteristics and textual variation. Analysis is performed in a generic way making few contextual assumptions. The contrast, size, orientation and resolution of the image are accounted for by...
