IEC 61850 makes new requirements on remote control for electric power equipment. This paper proposed an environment information aware model and gives a macro structure on the basis of middleware to facilitate new computing paradigms such as cyber-physical computing and service-oriented computing in Bulk Power System, and this desire is aiming to give suggestion on the issue of Cyber-Physical Power...
Soil erosion by water is a serious problem all over the world. In China, about 1 790 000 km2 of land suffers from water erosion, which accounts for 18.3% of China’s total area. This study was conducted in the Liao (潦) watershed in Jiangxi (江西) Province to assess annual soil erosion and sediment yield using the Universal Soil Loss Equation (USLE). A geographic information system (GIS) was used to generate...
Software cybernetics makes better use of the interplay between control theory and software engineering. A cybernetics method called self-evolving control is proposed to guarantee the behaviors' reliability of software systems at runtime. This method adopts software sensors to monitor the behaviors of runtime system, and achieves self-evolving based on feedback control and scheduling. The method has...
Researching on chaos-based image encryption scheme is becoming increasingly popular; unfortunately, most of the algorithms proposed provide poor security because of their failure to resist attack. A new digital image encryption scheme based on variable parameters double logistic systems is presented. The subkey sequences are generated after optimizing and adjusting from the chaotic maps which have...
