2007年国际电子商务、工程及科学领域的分布式计算和应用学术研讨会

作者： Wanneng Shu college of Computer Science, South-Central University for Nationalities Wuhan, 430074, china

In many real-life problems, objectives under consideration conflict with each other, and optimizing a particular solution with respect to a single objective can result in unacceptable results with respect to the other objectives. A reasonable solution to a multi-objective problem is to investigate a set of solutions, each of which satisfies the objectives at an acceptable level without being dominated by any other solution. In this paper, an overview and tutorial is presented describing genetic simulated annealing algorithm (GSAA) developed specifically for problems with 0/1 knapsack problem. Experimental results have shown that GSAA is superior to genetic algorithm (GA) and simulated annealing (SA) on performance.

Iron（Ⅲ）-doped nanostructure TiO2-coated SiO2 （TiO2/SiO2） particles were prepared using the layer-by-layer assembly technique and their photocatalytic property was studied. TiO2 colloids were synthesized employing the sol-gel method with TiChas a precursor. The samples were characterized by Fourier transform infrared spectroscopy （FTIR）, SEM, EDS, XPS, and XRD. The experimental results show that TiO2 nanopowders on the surface of SiO2 particles are well distributed, the amount of TiO2 is increased with the adding of coating layers, the pure anatase-TiO2 coating layers are synthesized at 500℃, and the photocatalytic activity of Fe^3＋-doped TiO2/SiO2 is higher than that of undoped TiO2/SiO2.

The liver is the commonest site of distant metastasis ofcolorectal cancer and nearly half of the patients withcolorectal cancer ultimately develop liver involved duringthe course of their diseases. Surgery is the only therapythat offers the possibility of cure for patients with hepaticmetastatic diseases. Five-year survival rates after resectionof all detectable liver metastases can be up to 40 %.Unfortunately, only 25 % of patients with colorectal livermetastases are candidates for liver resection, while the othersare not amenable to surgical resection. Regional therapiessuch as radiofrequency ablation and cryotherapy may beoffered to patients with isolated unresectable metastasesbut no extrahepatic diseases. Hepatic artery catheterchemotherapy and chemoembolization and portal veinembolization are often used for the patients with extensiveliver metastases but without extrahepatic diseases, whichare not suitable for regional ablation. For the patients withmetastatic colorectal cancer beyond the liver, systemicchemotherapy is a more appropriate choice. Immunotherapyis also a good option when other therapies are used incombination to enhance the efficacy. Selective internalradiation therapy is a new radiation method which can beused in patients given other routine therapies Without effects.

In the recently 20 years, grassland vegetation coverage change rapidly in Inner Mongolian Plateau, it both related to global climate change, and also closely related to is social and economic system in Inner Mongolia in the last 30 years. In this paper, Based on the relation between human and land theory as the guide, by using GIS and field survey method, with the Yihewusu Gacha of Abag Banner for research area, to take the four seasons pasture of districting rotational grazing as a unit, analyzes the changes of grassland vegetation coverage in the GaCha nearly 20 years. Results shows that [1]grassland degradation（grassland vegetation coverage decreased）;[2]the change of grassland vegetation coverage of districting at a quarter of rotational grazing is different, Vegetation coverage of summer pasture is highest, while the vegetation coverage of winter pasture is lowest. The analysis results showed that at present, "districting at a quarter of rotational grazing" one of more economical and effective method of protection natural grassland and restoration degraded grassland.

A novel approach to fault feature extraction using Weibull distribution parameters is *** the original signal of bearing vibration is modeled as the Weibull distribution,its scale parameter is extracted as a new feature vector for the bearing running *** tests results of fault diagnosis of the rolling bearing verify that this new feature can catch the regularity of changes in the information of bearing vibration more sensitively and accurately,and have higher separability suitable for pattern recognition by support vector machine classifier.
