Multiwavelet Boundary Element Method for Cavities Admitting Many NURBS Patches

Many Core Acceleration of the Boundary Element Method

The Intel Xeon Phi coprocessors provide an efficient tool for the acceleration of scientific codes. Contrary to the GPGPU programming, where the code has to be adapted to the hardware design of the graphics cards, the Intel’s MIC (many integrated core) technology allows for easy porting of the standard CPU code. One of the options to utilize the Xeon Phi coprocessor is to run the code on the CP...

A NURBS-enhanced Discontinuity-Enriched Finite Element Method

Generalized finite element methods have proved a great potential in the mesh-independent modeling of both weak and strong discontinuities, such as the ones encountered when treating materials with inclusions or cracks. By removing the constraint of a conforming mesh, more freedom is offered to modeling exact geometries by means of splines. However, very few studies have been published which com...

Rigid Chains Admitting Many Embeddings

1. Abstract A chain (linearly ordered set) is rigid if it has no non-trivial automor-phisms. The construction of dense rigid chains was carried out by Dushnik and Miller for subsets of R, and there is a rather diierent construction of dense rigid chains of cardinality , an uncountable regular cardinal, using stationary sets as`codes', which was adapted by Droste in 1] to show the existence of r...
