Cubic Co9S8 fracture structure nanoshells and cubic Co3S4 nanocrystallines were prepared by an ultrasonic spray pyrolysis process using cobalt chloride (CoCl2·6H2O) and thiourea (CH4N2S) as the starting materials. The as-prepared Co9S8 nanoshells and Co3S4 nanocrystallines were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) with energy-disperse X-ray spectroscopy (EDX)...
When predicting the noise level of substation, the model of transformers and reactors as noise sources is very important. A new acoustic mode of the transformers and reactors is built in ultra-high voltage substation. Each of the transformers and reactors is equivalent to several point sources based on equivalent source method. And in the process of the equivalent, the measurement and calculation...
This paper proposes the MLR (multiple linear regression) algorithm for parameter estimation of power system post-fault configuration based on the PMU real-time measurement and generator dynamic equations. Using real-time data collected by wide-area measurement system, the algorithm can take complicated cascading fault events into consideration without any information about the specific parameter and...
The logistics industry is the foundation and guarantee of the rapid development of manufacturing industry, and the manufacturing industry makes a huge demand for the development of logistics industry, therefore, it shows coordinated development trend between manufacturing industry and logistics. Using Logistic model, this paper gives quantitative research in the impact of Chinese manufacturing industry...
This paper studies how to coordinate a supply chain consisting of one supplier and one retailer with nonlinear price-demand function under market demand disruptions. Different from conventional research on channel coordination, it mainly focuses on how the demand disruption affects the coordination of the supply chain in which production cost is a convex function of production quantity It shows that...
This paper addresses coordination problem of a supply chain comprising one supplier and one retailer under production cost and market demand disruptions. Assume the market demand is sensitive to retail price in an exponential form, the optimal strategies are obtained for different disruption scale under centralized-decision system, and it is shown that the original production plan of the supply chain...
