Environmental stress screening (ESS) is a process to eliminate defects caused by materials and manufacturing variations in electronic products by a 100% screening, with the goal to eventually improve manufacturing processes that cause the defects. MIL-HDBK 344A- Environmental Stress Screening (ESS) of Electronic Equipment describes a quantitative approach for planning, monitoring, and controlling...
As the revolution of power market, the condition of energy and environment has become serious. It is an urgent problem on how to built a reasonable model of reserve markets. This paper describe the reserves market briefly, and then construct the model of co-optimization of energy and reserves as implemented in reserve markets. In this mode, it is discussed the reserves of generators in the condition...
For obtainment of facula area of external insulation ultraviolet discharge figure automatically and accurately, a facula area extraction method based on active contour models was proposed in the paper. Of the active contour models, the ultraviolet discharge region contour was obtained by calculation of partial differential equation. The algorithm has global optimization capacity, which is different...
To make the route searching results closer to driver's preferences, it is necessary to learn drivers' route choice behavior. Different from the existing methods, the paper analyzes driver route choice behavior based on frequent routes, which are the routes chosen by drivers frequently. In the method, route type preferences and frequent route popularity are analyzed. In the end, an application case...
