Based on the research achievements of Hallak and Schott, this paper goes deep into industry classification level of SITC7 products and constructs the quality index model for estimating China's native export products from year 2006 to 2010. And the export impact of processing trade and foreign-owned enterprises is excluded. The results show that quality of the native export products is significantly...
In some manufacture, process, the out-of-service of equipments could cause great economic loss or even industrial accidents, therefore, the critical spare parts of equipments must be managed through the constraint of zero-out-of-stock. Based on the inventory management of critical spare parts of manufacturing equipments, this paper builds the inventory optimization model of critical spare parts of...
Based on the assumption that plasma medium is cold, unmagnetized, collisional and inhomogeneous, a radar cross section (RCS) calculation model for complex targets shielded with plasma is presented. In high frequency region, the plasma that defilading a target can be treated as layered media. In each layer, the plasma is equivalent to a uniform dielectric. Physics optics (PO), ray-tracing method and...
Based on graphical hardware processor, a visual method of infrared image generation in real time is proposed. Four parts including target geometrical model, temperature distribution, infrared radiation computation and atmospheric attenuation are used to generate the infrared image step by step. The target can be modeled with CAD software using facets and every facet's temperature is changed in real...
