Size effects make traditional forming theories infeasible in analyzing the micro-forming process, so it is necessary to develop an accurate material model to describe the material flow behavior with consideration of size effects. By studying the size effects of the flow behavior of H80 foils experimentally, it is found that the foil flow stress and strain hardening ability reduce significantly with...
To restrain the CO2 concentration in atmosphere, deployment of the carbon-negative energy generation devices is indispensable on account of the vast net carbon discharge every year. In this work, a novel and promising quadruple fluidized bed (QFB) reactor for the biomass/coal co-gasification is proposed to generate the high-quality syngas whilst separate CO2 for further sequestration or utilization...
New power semiconductor devices, such as SiC MOSFET, have widely fascinated people in recent years. They are playing more and more important roles in modern power electronic converters. Most of current SiC MOSFET models are implemented in simple simulator, such as PSPICE, and have problems in some applications, for example, the accuracy of these models can not satisfy the demand with the increasing...
Criminal geographical profile is a methodology of investigation, which makes use of correlation between crime location and crime base of criminal to find out the most probable place of the crime base. We introduce a model to predict the future serial crime location with aid of criminal geographic profiling and the time and locations of past crime scenes. In this model, we take the effect of distance...
