On global optimal algorithms, a heuristic 0-1 Integer Liner Programming algorithm is achieved, which combines heuristic enumeration method and revised simplex method. Simulation experiments show that the degree and optimization efficiency in our algorithm is obviously improved compared with the MATLAB 7 bintprog function that is a 0-1 integer programming algorithm. Moreover our algorithm isn\'t relevant to the scale changes of Web services composition and candidate service sets, thus it is applicable for the scenes that the scales of Web services composition changed dynamically. But for Web services composition with service alliance, the algorithm is unable because the non-linear global optimal model of the fitness function and QoS constraints can\'t be expressed in linear mode.

A computer-aided local transient flow property measuring system was developed using a high speed CCD camera coupled with optical fibers in order to study the Gas-liquid-solid three-phase jet loop reactors. SnO2 crystal films were orientally deposited on the alkoxysilane molecule-coated hydroxyl glass substrates so as to prepare surface-marked particles as the tracers. An image analysis system was established to identify different phases. Stroboscopic photography was utilized to extend the measure range. The developed measuring and analysis system was capable of determining accurately the local transient flow property in a G-L-S jet loop reactor. Based on the above system, local transient flow properties of gas, liquid, and solid phase were measured and studied the influences of fluid property, operation and configuration parameters on the reactor.
