User fairness and spectrum efficiency are conflicting objectives in cellular system optimization given that users share limited spectrum resources. Users at the cell edge are more likely to be unfairly treated due to their disadvantageous locations, where they experience high path losses and strong interferences if co-channel transmission exists. In this paper, a cell edge boundary is obtained and...
Production line, taking on the most production task, is the important part in manufacturing enterprise. Under determinate resource, the running state of the production line has a great impact on the production capacity. This paper, aiming the aero-engine casing production line, makes a systematic study on production line simulation, builds the model of aero-engine casing production line, and makes...
In order to improve boiler efficiency and reduce NOx emissions of a coal-fired boiler, a new solution strategy of combustion optimization is proposed is this paper. The key point of combustion optimization is the optimal setpoints of fuel and air parameters. As the development of electric industry, large amounts of history data are accumulated and data mining technique is applied to find some useful...
