The results of several simulations for different high dimension benchmark functions illustrate that the proposed algorithm has both better ability of global exploration and local exploitation, and the optimal precision is effectively improved under the condition of guaranteeing the convergence of PSO algorithm.

This paper introduces a part-prototype development mode that integrates the advantages of waterfall development mode,traditional prototype development mode,UML and software engineering management techniques.

Based on wave mathematical model, this paper researches the law of redistribution of wave energy caused by partial excavation of waterway, and analyzes the influences of different excavation forms on wave energy concentration, for the purpose of solving engineering problems.

The wave forces induced by the interaction of oblique incident waves with partiallyperforated caisson structures have been investigated.
