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...
According to the linear relationship between the measuring data of Yangtze river, the index weight is decided by mean-variance method, triangle whitenization weight function and trapezoid whitenization weight function are established respectively to make grey evaluation for the present situation of water pollution of Yangtze river, finally the expectation results are approximate. This explains that...
In this paper, VC++ serves as a workspace to establish the features of speediness and navigation speed controlling. A mathematical model of intelligent propulsion system of an adjustable-pitch-screw-propelled hydrofoil sliding craft was built up, and then applied the fuzzy-genetic algorithm (FGA), to program the optimizing-computing process of the best combination of the controlling parameters of...
Communication based train control bring the possibility of moving block control of metro line. The system's transport capacity and punctuality in service depends on the capability of automatic train regulation. The automatic train regulation problem is essentially nonlinear and stochastic, and limited by operating hours of metro line. Neuro-dynamic programming with recurrent critic is shown able to...
Yield learning in modern technologies requires fail data logging from the scan and memory structural tests to gain insight into the failing location inside a chip.Currently there is no standard format to store the fail data in an efficient way. A group of more than 20 companies from ATE, EDA, Semiconductor and Yield Management companies has been working to enhance the Standard Fail Data log Format...
Based on a kind of typical high-speed monohull, this paper discussed an overall optimization's method of navigational performance and structure characteristic with the materials of some ships and some relevant experience expressions. In order to compare this method with others, the writer had also made up a software(VC++6.0). The result showed that the inequality hierarchical genetic complex method...
Performing data-mining tasks such as clustering, classification, and prediction on large datasets is an arduous task and, many times, it is an infeasible task given current hardware limitations. The distributed nature of peer-to-peer databases further complicates this issue by introducing an access overhead cost in addition to the cost of sending individual tuples over the network. We propose a two-level...
Data mining has attracted increasing interests in recent years. Although there are several data mining software suits available, it is not easy for an end user to apply data mining techniques without the help of the data mining expert. The difficult is that with huge amount of data mining algorithms, how to choose a set of algorithms appropriate to their data that can satisfy their requirement. In...
This paper presents a completely decentralized control scheme for the control of interconnected systems with unmodelled nonlinearity and interaction. The interaction due to interconnection and the intrinsic nonlinearity associated with a subsystem are represented by aggregative deviations of state derivatives from their linearized nominal values of the decomposed subsystems. Then, based on a model...
