The paper provides the method of the improved genetic neural network for image segmentation. The method uses improved genetic algorithm BP neural network weights and thresholds to optimize, and use the definition of bipolar fitness function mapping compression to speed up neural network training speed, and then use iterative improved neural network algorithm to achieve image segmentation. The results...
This paper proposes a new ABS (Anti-lock Braking System) control strategy based on braking time interval by analysis and simulation of braking process. Braking strength is an important influence factor of safety braking. In the whole braking process, with the change of braking time interval, the average braking force changes, and the strategy adapts to the need of braking strength in different road...
As a main defect, the crack has enormous threat on structure safety, which the great majority is mix-mode in engineering. At present, mix-mode crack analysis mainly depend on the manpower way to rebuilt continuously crack structure one by one to simulate the process of crack growth. And the process of modeling crack structure also is complex. To improve the analysis efficiency and provide fast decision...
Under the guidance of the theories of Complex Adaptive System and Artificial Societies, modeling and simulation of international politics evolution in crisis was studied. The Model of International Politics Evolution (IPEM) in crisis based on Agent was built. The function and architecture of IPEM were introduced. Individual Agent, including Nation Agent, International Organization Agent and Environment...
The effectiveness evaluation of C4ISR is playing a more and more important role in its designing, developing and using. According to its characters, such as complexity and intelligence, the traditional evaluation methods and systems are not feasible and effective enough. In this paper, a multi-agent based simulation and evaluation framework of C4ISR is advanced, which includes the architecture and...
Based on a kind of typical high speed monohull vessel, the paper discusses an integrate optimization's method of Synthetical Fundamental Mechanics Characteristic with the materials of some ships and some relevant experience expressions. The authors use the weighted sum of rapidity, sea-keeping ability and maneuverability as the sub-objective function of ship performances; use the weighted sum of static...
This paper proposes a new algorithm of generating command pulses for numerical controller. Different from the presently used NC pulse generating method, pulse train with automatically changed frequency following reference displacement commands can be generated using the proposed algorithm, and the generated command pulses can be modified in real time according to the reference signal. Moreover, by...
Gene pyramiding has been successfully practiced in plant breeding for developing new breeds or lines in which favorable genes from several different lines were integrated. But it has not been used in animal breeding, and some theoretical investigation and simulation analysis with respect to its strategies, feasibility and efficiency are needed before it can be implemented in animals. In this study,...
