Power network planning is a NP hard problem difficult to be solved. It can be contributed to similar TSP problem. Aiming at the slow convergence speed of the traditional immune clonal selection algorithm (ICA), adaptive immune clonal selection algorithm without memory（AICA）and adaptive immune clonal selection algorithm with memory(AICAM) are proposed respectively based on the combination of adaptive algorithm of clonal probability, immune probability , and group disaster algorithm. The two proposed algorithms have been applied to Power network planning problem. The adaptive algorithm has strong global search ability and weak local search ability at early evolution. Global search ability is weakened and local search ability is enhanced with the process of evolution in order to find global optimal point. The application of group disaster algorithm can enhance the diversity of the population and avoid the premature problems to some extent. Simulation results indicate that compared with the traditional immune clonal selection algorithm(ICA), the proposed algorithms can enhance the diversity of the population, avoid the premature problems, and can accelerate convergence speed in some extent.

Forging processes, such as liquid forging, rheoforging and thixoforging process, were used in this study as an effective method for manufacturing high-strength, finely-dispersed and highly-uniform AZ91D alloy parts. It has been found that although the microstructures of the three forging parts are all composed of α-Mg and β-Mg₁₇Al₁₂ phases, their shapes, sizes, numbers and distributions are all different, which also influences their mechanical properties. The tensile fracture morphologies were observed and their energy spectrums were analyzed by scanning electron microscopy. The results show that the cracks are mainly originated from the brittle fracture of the β-Mg₁₇Al₁₂ eutectic phases, whereas their fracture morphologies are greatly different, which indicate the direction for providing a reasonable forging process.

Northern Songliao Basin contains a large amount of oil shale resources. Due to the limitation of the oil and gas enrichment area, movable oil and gas and mining conditions, must determine the advantageous area of movable resource. Based on the improved Δ logR model, evaluated the organic matter abundance and residual hydrocarbon content; Based on the least squares method, established a model between clay mineral and well logging curve and calculated clay mineral content; Combined with organic carbon and residual hydrocarbon, evaluated movable oil amount. The evaluation results show that Qn1 Member favorable area mainly concentrated in the central and northern part of Qijia-Gulong depression and the middle part of Longhu Pond-Daan terrace; Qn23 Member favorable area mainly concentrated in Longhu Pond-Daan terraces middle part and southern and middle part of Qijia-Gulong depression. Qn1 Member movable oil resource is 150 million tons, Qn23 Member movable oil resource volume is 350 million tons, total movable oil resource of Qingshankou Formation is about 500 million tons.

The process of TiCl₄ treatment on the FTO substrate of DSSC were analyzed and the microstructures of substrates before and after treatment were observed. Further more, the influence of TiCl₄ treatment on the substrate of Dye-sensitized solar cell to photo-current voltage performance was numerical analyzed.

The study investigated the effects of mechanical stirring before solidification on the metallurgical structure of hypoeutectic aluminum-silicon A356. A series of stirring trials were conducted in the present study. Emphasis were placed on the morphological changes of the primary phase, which was subjected to different levels of stirring at various values of the rod material and its diameter, insertion temperature and rotation speed. It was found that when the rod was made of the same material as the molten metal, it acted as a nucleation site to generate numerous nucleated primary crystals, which separated from the rod surface continuously into the molten metal with the rotation of the stirring rod, resulting in the refinement and spheroidization of the primary crystals. The ideal semisolid slurry with homogeneous spherical and fine primary crystals could be obtained by optimizing rod insertion temperature, rotation speed and its diameter, which is a key factor in semi-solid forming.

More internal transistor of GPU is used as a data processing rather than process control. Compared with the existing multinuclear CPU, it has more processors and higher ability of the whole parallel processing, which is suitable for a large scale super calculation based on desktop platform. CUDA platform, put forward by NVIDIA Company, which is a new hardware and software architecture of realized the general calculation of GPU combined with the high parallel ability, and adopt CUDAC programming language to realize a parallel binary image connected domain label algorithm based on CUDA. The algorithm uses eight connection body labels, which has the high parallel ability, the less association between steps and the efficiency of the great promotion space.

Use concrete pressure testing machine to test the properties of Cement slurry , and conduct the ASTMC1202 penetration test of the properties and MIP which test the properties and microstructure characteristics. Base on the analysis of the relationship of cement strength and permeability, microstructural features. The results show that, with the increase of the permeability of cement slurry net of intensity decreased by 13%; The increase of pore volume total 11%, and the average pore volume rose 5%, cause pore internal loose, strength fell 0.74%; Cement of a few aperture increase to 7 nm, can lead to internal form lots of pore channels, intensity decreased. when the most several aperture is more than 10 nm, cement strength average less than 41.4 Mpa; Age can effectively passivation cement phase crystallization geometrical shape, and effective crystallization refined grain size.

Real estate mass appraisal is the key preliminary work of imposing real estate tax in urban area.Various methods have been used for real estate mass appraisal,among which geographic information system(GIS) is a powerful method to improve the efficiency due to it’s capacity of spacial analysis and management.This article tries to explore the combination of GIS and Hedonic model,and uses GIS spacial analysis function to quantitative analysis influencing factors of real estate.At last we have a real estate mass appraisal practice on Xi’an,the result shows it is feasible and efficient to apply GIS in urban residential real estate mass appraisal.

The risk factors of continuous incremental launching bridge during construction stage are specialized. The risk in incremental launching stage is analyzed and identified. A risk assessment index system is built. A fuzzy comprehensive evaluation model is developed. The results obtained from the risk assessment model verifies the validity and practicality of the developed method by the combination of analytic hierarchy process and fuzzy mathematics theory. Moderate risk assessment results are developed to provide references for incremental launching construction method.

In order to solve the problem in k-means algorithm that inappropriate selection of initial clustering centers often causes clustering in local optimum and the time complexity is too high when handling large amounts of data, a fusion clustering algorithm based on geometry is proposed in this paper. The result of experiments shows this algorithm is better than the traditional k-means and the k-means++ algorithms, with higher quality and faster speed. And at last in this paper, we apply it in marine engineering.
