In a semiconductor manufacturing process wirebonding is considered to the most key critical process steps. It is where the interconnection between the Silicon (Si) die to external package is made. On top of the first and second bond, wire looping is another challenge to consider specifically using Copper (Cu) wire. In general, Cu wire had a specific characteristic that cannot be directly compared...
In order to overcome the traditional clustering algorithms' defects of slow convergence and easily falling into local optimal solution, an improved immune clustering algorithm was presented. In this paper, chaos optimization mechanism was introduced into immune programming algorithm. By this means the improved algorithm can not only achieve global search performance and adaptive capacity, but also...
Fast and accurate fault diagnosis method is important for mobile robot's fault tolerant control and repairing. The traditional method may influence the accuracy of fault diagnosis when the system has a large model set because of the model competition. Traditional method generally use the extended kalman filter which has a law calculation accuracy. In this paper, combining the variable structure multiple...
In order to solve the modeling problem of complex objects with jump parameters, a hierarchical multiple model online identification method based on mechanism of antigen identification was proposed. In this paper, through training the input-output data the model set was acquired to act as a classifier to divide the uncertain space of parameters into several small subspaces. In these subspaces, the...
A new Fuzzy Identification Method for T-S model identification algorithm is proposed, based on cats swarm and least squares method. T-S model identification is divided into structural and parameter identification. In the structure identification using cats warm can effectively overcome the traditional clustering algorithms exist slow convergence and easily fall into fall into local optimal solution,...
With guaranteeing full observability of the power grid and acquiring a good balance between the cost and the capability of phasor measurement unit (PMU) placement, the observability criteria of power grid nodes and the N-l reliability principle to judge the measurement redundancy of placement schemes were proposed in this paper, and a mathematical model of multi-objective optimization for PMU placement...
