Based on system dynamics modeling method, the nonlinear model of the cloud computing virtual machines scheduling is built. With system dynamics methodology and the use of simulation tools, from a system perspective on cloud computing service requirements and building scale, the key factors affecting the number of cloud computing machines are identified. Furthermore, mathematical statistical theory...
Recently wind energy has developed at a fast pace, and it is necessary to develop equivalent models to represent dynamic behaviors of wind farms on power system. The equivalent wind method has been investigated for the aggregation of DFIG wind turbines. The detailed procedure for the calculation of equivalent wind has been analyzed. The necessity of classifying incoming winds has been shown. In order...
In this paper, we established rigorous relationship between target recognition performance and the parameters of a fixed waveform via Kullback-Leibler information number of single observation (KLINs). The method we proposed takes advantage of the methodology of sequential hypothesis test. It depicts the target recognition efficiency of certain radar waveform parameter in the metric of average number...
Routing protocol simulation is the basis for its practical application. Using multithread simulation technology can not only simulate the performance of routing protocols, but also lay good foundation for its hardware porting. By use of the technology and combing with Winsock, the paper researched on routing of wireless communication and brought out a kind of computer simulation method for distributed...
The paper introduces about temporal logic of action, it discuss the relation among closure, security, fairness property and liveness property in TLA, action and point out and weak fairness and strong fairness as prerequisites, base on this, it discrible in detail how to establish system model with machine-closed through cases, in the end we gain correct conclusion.
Because of the huge cost, the high demand of sensors and the limitation of observation for ballistic missile in outfield measure, the acquirement of measured data is certainly difficult. Moreover, as the radar echo is modulated by the high-speed and micro-motion of ballistic missile, the ballistic missile's RCS generated by electromagnetic software differs greatly from the measured data. In this paper,...
Plants simulation is a challenging research domain. Under the condition that external environment affect trees, the paper proposes that adopting illumination model as plants-growing simulation mechanism, optimizing and adjusting external-environment parameters with genetic algorithm, and simulating the plant-growing process well. Experiments results show that using phototropism of plants and influence...
