A number of robust, and computationally efficient, algorithms are presented for the development of an overall strategy to estimate the material parameters characterizing a class of complex viscoplastic material models (i.e., rate dependent plastic flow, nonlinear kinematic hardening, thermal/static recovery, isotropic and anisotropic, etc.). The entire procedure is automated through the integra...

abstract background: inadequate dialysis is one of the main causes of mortality of the patients undergoing hemodialysis. the methods that lead to improvement of dialysis adequacy in these patients are of great importance due to them causing an improvement of quality of life. as numerous factors can play a role in improvement of dialysis adequacy, the present study aimed to investigate the level...

The flow properties in a granular system confined by a rapidly rotated bottom surface and fixed walls are investigated. Above sufficiently high rotation rates the system enters a state in which the flow is independent of the driving rate. Further, a nearly constant shear-strain rate is measured throughout the entire system. Optical and particle imaging velocimetry methods are used to measure th...

In order to curb environmental impact, absolute resource use reductions are urgently needed. To reach this goal, multi-scalar synergies and trade-offs in global resource use must be effectively addressed. We propose that better understanding the role of extractive economies— economies that extract raw material for export—in global resource use patterns is a prerequisite to identifying such syne...

The rapidly developing, worldwide marketplace is leading to the geographical dispersion of production, assembly and distribution operations. This paper deals with three aspects of international logistics networks: strategic, tactical and operational. The strategic level designs the logistics network, including prescribing facility locations, production technologies and plant capacities. The tac...

In metal forming operations, the intensity and distribution of stresses at the tool/material interface have great influence on the pattern and mode of deformation. This is due to the effect of frictional forces in being resistive to material movements and hence affects material flow and the directionality of volume distribution of material inside die cavities. This paper explores the use of the...

Tremendous growth of the home information appliances requests semiconductor manufacturing to respond High Product Mix and Low Production Volume condition. Such condition in manufacturing operations challenges production management to have rapid improvement activities in an environment with uncertain productivity and demand. In this research Visualized Coefficient of Variation Analysis (VCVA) wa...
