Abstract: To improve the efficiency and effectiveness traditional algorithm which still has some shortcomings, this paper combines with the advantages of genetic algorithm, brings forward a routing algorithm based on novel heuristic genetic algorithm (NHGA). The simulation results show that this algorithm overcomes the shortcomings of genetic algorithm. From the analysis and experiment result, it is concluded that NHGA was exploited to achieve the goal of improving the routing performance, and is superior to genetic algorithm simultaneously.

Abstract: With the help of enterprise information technology wave, a lot of internal information resources have come out. Enterprise search achieves more accurate positioning information, and it realizes the value from the information across to the knowledge. This paper discussed the enterprise search systems based on database security services. Such as Oracle Ultra Search, Sybase Enterprise Portal and LogicSQL-based enterprise archive and search system. The enterprise information resources integration and security search are completed in the search system.

Abstract: In order to make clear the basic law of college students’ athletic trauma, This paper made a survey through random sampling. As the result shows, the trauma chiefly occurs on limbs, with pulled articular ligament, skin abrasion and pulled muscle as its main types. It often happens during extracurricular athletics and physical education, when students take part in games such as track-and-field events, volleyball and basketball. The major reasons for those accidents are poor skills and insufficient warming-up exercises.

Abstract: In this paper,it proposes insulator flashover probability prediction model based on Markov chain and ARMA-GARCH. It provides a foundation for risk evaluation of rainstorm of power system. First,this model daily precipitation forecasting model which combined Markov chain with ARMA-GARCH based on self-dependency and time-varying of atmosphere factor; and then according to rainfall’s impact on insulator’s pollution raining flashover,the paper raises the probability prediction model of insulator flashover;Ultimately, we can predict the insulator flashover’s probability. Through Historical data of Hunan Grid to calculate the probability of flashover, and compares with the actual situation it shows that the method can achieve rapid, accurate prediction of power insulator flashover probability.

Abstract: Information management professional is a comprehensive and practical characterized disciplines. students graduate from the professional should have a strong practical and innovative ability to adapt the needs of society. First, this paper analysis the social requirements for the students. then it proposed a new innovative training model based on a practice training camp project to meet the society. Finally, it presented the framework of project training camp and implemented the corresponding web site. The training camp has effectively enhanced the ability of applying knowledge and technical capacity, and at the same time stimulate their innovative capacity.

Abstract: PLC dynamically adjusts power voltage by controlling switches of transformers with different combinations, which is based on the theory of 8421, and makes voltage changes in a very small range. By using this system, energy is saved, and the damage of illumination equipment from voltage instability is greatly reduced, and the life of lamps is effectively extended. Meanwhile, by using the touch screen, this system not only can realize the real time parameter display, but also achieve the real time operation on the panel.

Abstract: In mathematics science, subtraction is rather simple computation of arithmetic. However, no matter what advanced computer in the world, and no matter what backward calculator (such as abacus in China etc.) in people’s hand, to get difference of subtraction is always a NP problem in all the time. Such as capacities of numbers Minuend and Subtrahend, symbols (±) of number value (positive number or negative number), precise computing (PC), computing precision (CP), perturbation motion (PM) in computing of numbers, etc. This paper makes an algorithm of novel subtraction with AI-VCR computation in computer, and gives solutions of avoiding the difference’s overflowing, insufficient valid figures, etc.

Abstract: This paper promotes an AI-VCR technology of searching without information. VCR is an extension of FCR(Fixed Carrying Rules) which is also computation rules of FCN(Fixed Carrying Numbers). The FCN are some special examples of VCN(Variable Carrying Numbers). DFS(Depthfirst Search) is a blind searching without information. In AI-VCR technology, AI(Artificial Intelligence) is used in dynamic designing computation rules of VCN. Both FCR and VCR in searching without information are variables of nodes’ depth function. Finally, it gives out some examples of problem-solving method, namely problem-solving such as catching fish with casting a net or herdsman picks peaches with his fierce-looking before climbing up a tree.

Abstract: An optional spatial 3D material solid reality picture may be showed on a 2D showing plane, its surface is commonly consisted of too many sub-surfaces of the 3D solid reality picture in both dispersal and continuation. It was a difficult problem to express all exact visibilities of solids sub-surfaces; because of some numerals computational error properties of visibilities are always unknown. So far, we cannot choose but select a proper dispersal degree of materials sub-surfaces, an approaching function of an optional material sub-surfaces B-Rep (Bound Representation), and numerals computation without any perturbation motion, etc. A novel numeral computational method of expressing exact visibilities of 3D spatial materials solids reality pictures with intelligent properties of VCR is given in this paper.

Abstract: DBioSearch is a distributed model optimized for indexing next-generation exploding sequence data including the human genome and other biological sequence data. It is modeled in view of the distributed programming and text search engine Lucene, and reports good indexing efficiency for each kind of biological datasets. Indexing on large volume of sequences could be time consuming, but DBioSearch uses the distributed programming skill to parallelize indexing process that can take advantage of multiple computing nodes.
