Abstract: Considering the deficiency of Traditional Genetic Algorithms(TGA)in solving combinatorial optimization,a Partheno Genetic Algorithm(PGA) is proposed.PGA does not use crossover operators of TGA,while use gene exchange operators that have the same function
Abstract: In this paper,the conductivity,pH,dissoived oxygen,density,evaporativity and IR,NMR,UV spectrum of magnetie water under various magnetized condition have been studied.It is found that pH,dissoived oxygen and evaporativity are increased,UV absorption peak
Abstract: Using strain model for structural damage diagnosis is one of new research topics.Authers studied the principle and method of strain model measurement theoretically.From the test and analysis of concrete frames,it is proved that strain model is more sensit
Abstract: The oscillation of neutral difference equation with continuous arguments is discussed.Some sufficient conditions for the oscillation of solutions of the eqution are established.
Abstract: The homogeneous solution of the differential equation for the shear lag in thin walled box girders is taken as the displacement pattern of finite element. Based on the variational principle, a finite segment method is proposed for analysing the shear lag
Abstract: In this paper, we consider the least-square approximate solutions of a class of matrix problems. The expression of the solutions is provided and a numerical method is described.
Abstract: Based on the current m method hypothesis,an analytical solution to deflection and internal force of flexible piles under inclined loads is presented in this paper,and model tests of flexible piles under inclined loads at various angles are carried out wi
Abstract: The experiment and aplication shows that the clay cement slurry is suitable for grouting curtain in the Nanchang rubbish buried site.The grouting curtain has hige anti permeatinon effectivity and low cost.
Abstract: A method to prepare one dimensional nanoscale composite based on coating of carbon nanotube with metal is proposed.It is found that the complete and satisfactory silver coating on carbon nanotube is achieved by electroless plating.It is also found that th
Abstract: Based on an intensive investigation on the principle and processing of conventional spray deposition technology,a new concept termed as multi layer spray deposition (MLSD) is presented,a novel multi layer spray deposition technology is deveploped to pro
Abstract: By using the generalized singular value decomposition,we give the gener-al solution of a kind of minimization problems. The sufficient and necessary conditions for the existence of the solutions to the corresponding matrix equations are obtained and the g
Abstract: Based on the analysis of grey incidence, which is an important part of grey system theory, this paper assesses indoor air quality by the abundant information provided by grey incidence matrix. According to the analysis and comparison with other methods, i
