slab method of analysis has been used for solving metal forming problems for a long time. however it has been restricted to plane strain and axisymmetric problems due to limitations in its formulations. in this paper a new formulation has been proposed so that it could be applied to three dimensional problems in metal forming. a parametric slab has been considered in this analysis and the force...

Hubble Space Telescope (HST) observations reveal that the density of stars in most elliptical galaxies rises toward the center in a power-law cusp. Many of these galaxies also contain central dark objects, possibly supermassive black holes. The gravitational force from a steep cusp or black hole will destroy most of the box orbits that constitute the " backbone " of a triaxial stellar system. D...

es wird gezeigt, dass bei der standiger zunahme der production von roheisen ,die fast ausschliesslich in hochofen erfolgt, der gestelldurchmesser und die ofeneinheit zunimmt demgegenuber der spezifische brennstoffverbrauch abnimmt. weiterhin wird die entwicklungsrichtung der stahlerzeungsverfanren wegen der wirtschaftlichen und technischen hinsicht untersucht und festgestellt, dass nuter versch...

A new slit-radial die capable of simultaneously obtaining steady state shear viscosity and the average first normal stress difference coefficient via capillary rheometry has been developed. The are calculated in slit part radial die, respectively. from is compared to viscosities obtained a also magnitude complex oscillatory experiment. value which transient experiment cone-plate geometry molecu...

MOTIVATION To study lowly expressed genes in microarray experiments, it is useful to increase the photometric gain in the scanning. However, a large gain may cause some pixels for highly expressed genes to become saturated. Spatial statistical models that model spot shapes on the pixel level may be used to infer information about the saturated pixel intensities. Other possible applications for ...

W over 500,000 women and girls die of complications related to pregnancy and childbirth each year. Over 99 percent of those deaths occur in developing countries such as Ghana. But maternal deaths only tell part of the story. For every woman or girl who dies as a result of pregnancy-related causes, between 20 and 30 more will develop shortand long-term disabilities, such as obstetric fistula, a ...
