On account of low convergence of the traditional genetic algorithm in the late,a hybrid genetic algorithm based on conjugate gradient method and genetic algorithm is proposed.This hybrid algorithm takes advantage of Conjugate Gradient’s certainty, but also the use of genetic algorithms in order to avoid falling into local optimum, so it can quickly converge to the exact global optimal solution. Using Two test functions for testing, shows that performance of this hybrid genetic algorithm is better than single conjugate gradient method and genetic algorithm and have achieved good results.

In view of poor accuracy and slow calculation of the traditional on-line handwriting signature verification, an on-line handwriting signature verification based on Early Abandon Dynamic Time Warping (EADTW) was designed and implemented after numerous researched. The training template followed the mechanism of benchmark signature, while the certification part adopted EADTW algorithm. The experimental results showed that compared with on-line handwritten signature system based on DTW (dynamic time warping), this new system not only greatly reduced cumbersome and repeated calculation, but also obviously improved the accuracy, The bigger the test sample is, the more obvious the advantage is.

The intake tower of the hydropower station is a high-rise underwater hydraulic building whose seismic safety is enormously important. Taking the effect of foundation and hydrodynamic pressure into account, we apply the ANSYS for the static and dynamic analysis which evaluate the seismic behavior of the intake tower. The result which provides the basis for the improvements shows that the rigidity of intake tower meets the requirement. After taking some engineering reinforcement measures, the strength also meets the requirement.

This paper mainly studies application of formal design for security protocols in digital campus. With a comprehensive analysis on security requirements of information transmission in digital campus, an information transmission model is built from the viewpoint of information security. Based on this model, a new security protocol, called DCIT for short, is designed. The formal analysis shows that secrecy, integrity, availability, controllability, non-repudiation and identifiability of information during transmission could be insured by DCIT, which could be used as a direction for development of various application systems in digital campus, from the viewpoint of information security.
