Secant pile walls are crucial in the construction of fossil-fuel power plants for water exclusion purposes. The construction time is the most critical factor that influences the entire construction project. Thus, shortening the time needed for building secant pile walls requires further investigation. Secant pile walls are not required to be constructed in any particular order; typically, site engineers...
The typical models and algorithms of energy saving control for a train are introduced and summarized. According to one of energy-efficient mathematical models which usually use GA algorithm to solve, a new algorithm based on particle swarm optimization is applied for the model. Through calculation for a cited example, simulation results such as speed-position curve are got. Compared with other methods,...
This paper proposes an image retrieval method based on multi-feature similarity score fusion using genetic algorithm. Single feature describes image content only from one point of view, which has a certain one-sided. Fusing multi-feature similarity score is expected to improve the system's retrieval performance. In this paper, the retrieval results from color feature and texture feature are analyzed,...
Under incomplete information system, the reduction of attribution based on rough set theory is an important but difficult task, and researches have already proved that finding minimal relative reduction is the NP complete question. Regarding to the complete decision-making table, there have been many methods to find the minimal relative reduction, but for incomplete decision-making tables, researches...
Facing the complex air defense situation, it is an urgent mission to improve the efficiency of regional air defense weapon-target assignment of warship formation. The weapon-target assignment problem is NP hard. Classical methods for solving such problems are based on graph search and usually result in exponential complexities. Some intelligent algorithms usually result in local optimal. An improved...
FIR filters are very important in digital system design. The fix-point hardware implementation of FIR filters has the advantages of low cost and high performance. But this kind of hardware implementation introduces the unavoidable quantization error. In this paper, we present a combined method of GA and the local-search to optimize the coefficients of finite wordlength FIR filters. The search ability...
