Abstract: With the character of mining method selection, in this paper, the author has developed neural network expert system for mining method selection. Its principle and structure are described. The application shows that the nenral network and oxpert system will be widely applied to mining engineering.

Abstract: Continuous speech recognition and automatic speech translation are important subjects. In this paper, our results on these topics are introduced. In recent years, a medium vocabulary speaker-dependent continuous speech recognition and English-Chinese speech translation system have been implemented in our laboratory. From now on, large-vocabulary speaker-independent continuous Chinese speech recognition should be studied to improve the speech technique and to speed up its applications.

Abstract: With models of Fuzzy Petri nets and general Fuzzy Petri nets, this paper presents a new method for fuzzy production rules of a rule-based system which allows clear representation and easy analysis of concurrency and asynchronous reasoning Algorithms for reasoning are also proposed, and the description of the model and fuzzy reasoning algorithms are described in detail

Abstract: Portfolio investment is a complicated combinatorial optimization problem,and is a NP-hard problem,which is difficult to be solved by traditional algorithm.In this paper,a quadratic particle swarm optimization(QPSO) is applied to solving the problem of portfolio investment optimization.In addition,self adapting parameters are applied.The result of the experiment shows that the QPSO can both escape local optimum and speed up global optimal convergence,and outperforms particle swarm optimization in some sense.
