Claster parallel computing and SSE instruction optimization technology are applied to the FDK algorithm and the algorithm is realized on an 8 nodes cluster.

In order to effectively control traffic flow,and synchronously optimize phase,period and green time at intersection,cell transmission model(CTM)and bi-level programming method were studied,and a signal optimization method was proposed.

With the application of information diffusion principle of fuzzy information optimization processing method,based on the 60 sets of collapsing loess data from test,the fuzzy relationship between the coefficient of collapsibility and the pore-solid ratio,moisture content which is selected from important influence factors is built.

The relation between structural stability of unsymmetrically loaded tunnel and original data is established with the help of the information optimization theory,and the tunnel stability is evaluated with these data.

In order to change such a situation, must transform theconception, strengthen the information consciousness takingthe computer and the network as the carrier and the media, anddo well the work of the information optimization for the purpose of meeting the needs of the teaching and scientific researchofthe university.
