As the development of science and technology, intelligent electrical appliances are increasing, gradually introducing the embedded microprocessor software to replace hardware to complete the functional and safe control has become an inevitable trend. As the electrical use is directly related to the safety of persons and property, so the safety testing and reliability testing of software are especially...
This paper studies the closed-loop supply chain composed of one manufacturer and two retailers, and uses the game theory to analyze the decision model. The papers written always were under the certain demand. However, the demand, in reality, is uncertain, so the random price-dependent demand is contained in this paper, and this paper discusses the impact of remanufacturability on the closed-loop supply...
In this paper, the accident of the voltage imbalance in Tianmashan substation is analyzed, which is a typical accident of 35 kV power system. Based on the ATP-EMTP simulation tool, the simulation model is built for analysis of the accident. And the causes of the voltage imbalance are analyzed. Finally the rectification measures are put forward for the transmission line design and construction.
Under pitch excitation, the sloshing of liquid in circular cylindrical tank includes planar motion, rotary motion and rotary motion inside planar motion. The boundaries between stable motion and unstable motion depend on the radius of the tank, the liquid height, the gravitational intension, the surface tensor and the sloshing damping. In this article, the differential equations of nonlinear sloshing...
