Protective relays are designed to quickly and correctly clear the fault and minimize the impact of disturbances on power system. Occasionally, some complex conditions may cause relays to perform unintended or incorrect operation, which may further deteriorate the system condition and even jeopardize the stability of the entire system. This paper discusses three categories of solutions for analy...

bone matrix gelatin (bmg) has been used for bone induction intramuscularly and subcutaneously by many investigators since 1965. more recently, some of the researchers have used bmg particles for bone repair and reported various results. in present study for evaluation of bone induction and new bone formation in parital defects, bmg particles were used in five groups of rats. the bmg was prepare...

Dealing with merge conflicts in version control systems is a challenging task for software developers. Resolving time-consuming and error-prone process, which distracts developers from important tasks. Recent work shows that refactorings are often involved refactoring-related tend to be larger, making them harder resolve. In the literature, there two refactoring-aware merging techniques claim a...

In the scene of paddy field rotary tillage, a real-time detection method tillage condition based on machine vision is proposed, and quality evaluated by index residual stubble. The root stubble selected as research object, standard deviation Y component in YCrCb space proposed to determine soil after which divided into three levels: less stubble, medium more Finally, accuracy algorithm verified...
