The universal formula optimized with feedback mutation genetic algorithm was used in evaluating some cases and compared with other methods,results showed that the formula which is simple,comparable,universal and practical is free from the restriction in kinds and numbers of pollutants and easy to calculate.

The task of this dissertation is to study the general CBR and the Introspective CBR and come up one of methods to resolve the problem which multi-user CBR systems face to.

Application of a feedback algorithm based on ABEL-HDL language to PLD design;

In this paper,the effect of feedforward algorithm,feedback algorithm and hybrid algorithm are com-pared by simulation,and verified on the experiment setting with the loudspeaker and the fan as the noise source.

The feedback calculation method for settlement is a method in which, the theoretically calculated settlement curves are being constantly fitted in with the measured settlement curves and, during the fitting process, the e-p compressive curves and the coefficient of consolidation are adjusted to make the theoretically calculated settlement closer to the measured.
