In order to improve the fitting precision of telemetry apparent velocity, the question of finding spline fitting optimum nodes of telemetry apparent velocity is solved by the PSO algorithm. The method of parameter setting is given in the paper, and the computer simulations are done. The calculation simulation results show that the fitting effect by PSO algorithm is better than that by equidistance...
Traditional approach for product family forming is based cell manufacturing system and design/product structure oriented. In this paper, an innovative methodology for product family forming is presented to effectively cope with customized demand. The methodology is designed under product-family specific production line (PFPL) environment and the criteria for product family forming are based on manufacturing...
In order to cut down air-condition energy consumption in the communication room and reduce the heat island effect partially, through the use of CFD (computational fluid dynamics), we have a study on airflow characteristics in communication engine-room. On the basis of established mathematical and physical equation about airflow characteristics, we try to get the numerical solution, and analyze the...
