The traffic jam of urban road is one of the important issues of common concern to the international community, which affects the efficiency and quality of city life. In order to solve the urban road traffic congestion problem, this paper gathers information and data about a five forks by the Work Sampling and image analysis method. Then, according to the queuing model of M/M/1, these parameters as...
This paper advances a method to develop simulation system, which is based on VC++ 6.0 and MultiGen Vega, and takes the mathematical model of Photoelectric theodolite and target as the theoretical basis. We modeling the simulation system by MultiGen Creator,and then drive the simulation models through MultiGen Vega, program under the circumstance of VC++6.0, simulate the work situation of theodolite...
LG type vacuum freeze dryer vapor captor is taken as the study object, and a mathematical model of frost heat transfer of the vapor captor was established, the effective heat capacity method was used to simulate the heat transfer processes of vapor captor. Frosting mechanism under low temperature and low pressure condition was investigated, and the changing relation curves of temperature distribution,...
Mathematical model of melting problem of phase change material (PCM) in cool storage tank was established. Moreover, the effective heat capacity method was used to simulate the heat transfer processes of cool storage tank, the changing relation curves of melting ratio, temperature and the diameter of cool storage tank along with time were obtained. The results show that the time of the ambulatory...
The Hinfin state feedback control for the stabilization of the three Euler angles of helicopter is studied. The little perturbation model of helicopter is introduced. The proper generalized control variables are chosen and the generalized control object is established. The Hinfin state feedback algorithm is developed based on the Iterative Linear Matrix Inequality (LMI) approach and the digital simulation...
