Solidification/stabilization effect of FeSO4 and Ca(OH)2/CaO on chromium contaminated soil were studied by contrast, especially the effect of its reaction interval time and concentration. The change of S/S effect with time was also discussed. Results reveal that the reaction interval time effected on S/S slightly, with the high quality ratio of water to soil. As FeSO4 and Ca(OH)2 was used as the S/S...
Customer perceived value is the crucial basis for customers to choose which eStore to purchase goods. To enhance customer perceived value is an important approach for eStores to construct their competitive advantages. The factors influencing customer perceived value are often not quantified, however they can be prioritized by AHP Method so that eStores can use these factors to enhance customer perceived...
Parameters setting is an important problem of evolution algorithms, include differential evolution algorithm. It has an effect on the performance of evolution algorithms. Although there is only three control parameters in differential evolution (DE) algorithm, the parameters setting is also a difficult problem. Self-adaptation is highly beneficial for adjusting the control parameters, especially when...
