INCREASING interest in the cyclic behaviour of man and animals has been evidenced in recent years, especially in so far as these cyclic changes are related to glandular disturbances. In studies of the spontaneous activity of rats the following cycles have been observed: a 4-5-day cycle associated with ovulation (Wang, 1923) ; a 14-day cycle after section of the pituitary stalk (Richter, 1933) ;...

We have benchmarked dual-processor quad-core AMD Opteron 2350 and 2356, dual-processor quad-core Intel Xeon E5345, single processor quad-core Intel Xeon X5472, dual-processor dual-core AMD Opteron 2214, dual-processor single-core Intel Xeon EM64T and single-processor single-core Intel Xeon EM64T systems using a CMSSW event simulation and reconstruction application. The results are presented in ...

The purpose of this paper was to investigate the reason why the interface delaminations occurred in the QFP structure. The stress concentration was the key factor responsible for the microcrack occurrence. In order to figure out which factors affect the stress distribution, the material’s attributes and the structure’s dimension were considered. The finite element program ABAQUS6.9 together wit...

Recently the study and construction of quad/triangle subdivision schemes have attracted attention. The quad/triangle subdivision starts with a control net consisting of both quads and triangles and produces finer and finer meshes with quads and triangles. The use of the quad/triangle structure for surface design is motivated by the fact that in CAD modelling, the designers often want to model c...

Unless an all quadrilateral (quad) finite element mesher is of a high quality, the mesh it produces can contain misshapen quads. This paper will describe “CleanUp”, written to improve an all quad mesh. CleanUp looks at improving node connectivity, boundary and flange patterns, quad shape, and to some extent, quad size. CleanUp is currently used in conjunction with the Paver algorithm developed ...

We consider discrete nonlinear hyperbolic equations on quad-graphs, in particular on Z2. The fields are associated to the vertices and an equation Q(x1, x2, x3, x4) = 0 relates four fields at one quad. Integrability of equations is understood as 3Dconsistency. The latter is a possibility to consistently impose equations of the same type on all the faces of a three-dimensional cube. This allows ...

In this article we study a nonlocal equation involving singular and critical Hardy-Sobolev non-linearities, \[\displaylines{(-\Delta_p)^su-\mu \frac{|u|^{p-2}u}{|x|^{sp}}=\lambda u^{-\alpha}+\frac{|u|^{p_s^*(t)-2}u}{|x|^t}, \quad\hbox{in }\Omega, \\ u>0,\quad\text{in }\Omega,\\ \quad u=0, \quad\text{in } \mathbb{R}^N \setminus\Omega }\] where \(\Omega \subset \mathbb{R}^N\) is bounded domain...
