Abstract: The key technology research and development projects of national vehiclenetworking system needs, software products and components, developed withindependent intellectual property rights and core technologies based onimproved Dijkstra algorithm Nanchang road congestion adaptive system based onmicro-channel real-time interaction; main contents of transportation forNanchang adaptive significance of congestion vehicle networking applications,the status quo and research problems. GPS has immediate feedback andmicro-channel platform for mutual exchange of powerful features. Thuscountermeasures to enhance vehicle networking applications, Jiangxi Science andTechnology Park level. Developed based on the GPSNanchang traffic congestion adaptive micro-channel platform system, thesoftware product has low prices, professional, practical, easy installation,simple operation, with independent intellectual property rights, perfectlysuited for automotive units practical operation. Has a strong competitiveadvantage. The research results can be widely used in the province actual carservice units (including the use of e-commerce), a system price of Wu Yuan,automotive service products can be formed in Jiangxi Province, the developmentof new industries and generate significant economic benefits.

Abstract: Haptic technology again receives extensive attentions recently by virtue of improvement on Internet Technology. This paper presents an applicable platform for Haptics by employing physical features of sense-of-touch through electromechanical devices and the latest attractive HTML standard specified by W3C, aims at offering new attributes and reliable communications with the ease of use for web content. In addition, the proposed platform demonstrates its significance on wrapping up fundamental rendering methodologies including Haptics and web graphical content, is a step forward in supporting study of all fields related to web-based interactive content (e.g., Haptics researchers, physicists, software engineers, and web designers). Finally, we provide a conceptual example of proposed platform and prove its proficiency on haptic data communication. The results of the experimental evaluations highlight the effectiveness, stableness, affordance and extensibility for future research.

Abstract: Animproved particle filter algorithm which based on mean shift algorithm isintroduced. The algorithm makes the particles move towards the high likelihoodregion in posterior distribution with the effect of mean shift algorithm,increases the efficiency of the particles moving, and reduces the phenomenon ofdegradation and dilution of particles

Abstract: This paper presents an interpolation-based method for multidimensional extrapolation. A series of interpolation formulations are proposed to extrapolate functions normal to the interface between two regions. Theoretical proofs and relevant analysis are also presented. The method developed maintains the characteristics of implicit interface. The interface inside every cell is treated smoothly by assuming that curvature is equal everywhere. The method developed and numerical results are verified by comparing to the results by PDE method and theoretical results. Numerical tests demonstrate that the method developed is first-order accuracy and also more efficient in numerical implementation and more accurate than PDE method.

Abstract: In view of the bestsolution of chemical control agricultural pests, we first build and analysisthe pest management model of spraying insecticide, the crop efficacy model and thedose model of the surrounding environment according to impulsive differentialequations. In view of the aperiodic solution model, we will find out theoptimal dose for the pesticides and time interval for sprayingby using optimal control theory, which can make the residue of the dose for thepesticides in crop and for the pesticide spraying the surroundings reach theminimum, make the number of pest under economic damage threshold at the sametime , and give the best solution to control agricultural pests by using the pesticides.At last, we explain the implementation of the scheme through the numericalsimulation.

Abstract: This article gets thepopulation data based on China Population Statistics Yearbook ,and establishes a model for forecasting thegrowth of population grouped by ages. First, a difference equation model invector form is established for urban area, town and rural arearespectively. In equation (I), matrix is determined byfertility rate and survival rate of urban area, townand rural area respectively. The short-term population size predicted from thismodel has calculated the gross population of each year during 2002~2020. The 19data we got were used to generate a function between population size y (hundredmillion) and time x (year) by polynomial fitting : , and the max of this function is y = 1.47121 billion when x= 20, which means that the Chinese total population will peak at 1, 471, 210,000 in 2021.

Abstract: With the rapid development of computer networktechnology, and also can be used as well as the increasing number of users ofcomputer network, how to effectively guarantee the network information securitybecomes a key technology of computer network. This paper through the literatureinvestigation method to build the information system security risk evaluationindex system, and combining the expert evaluation process could not get all theinformation in the information system security, a method of information systemsecurity risk assessment is put forward. Was carried out on the key technologyof information system based on big data discussion and analysis, and brieflyintroduces its development prospects. Secondly illustrates the necessity ofintrusion detection, and the concept of intrusion detection and the model isgiven. Finally summarizes many kinds of intrusion detection method and thesystem structure, discusses the existing problems of this field and theresearch direction in the future.

Abstract: With the development of modernization, how to implement the unified management and real-time monitoring becomes a key problem. With the requirements of Wuhan Heavy Duty Machine Tool Group Corporation, a CNC online monitoring system based on FANUC and Siemens system has been developed.

Abstract: Knowledge Management of Mathematics Concepts was essential in educational environment. The purpose of this study is to provide an integrated method of fuzzy theory basis for individualized concept structure analysis. This method integrates Fuzzy Logic Model of Perception (FLMP) and Interpretive Structural Modeling (ISM). The combined algorithm could analyze individualized concepts structure based on the comparisons with concept structure of expert. The empirical data is Basic Mathematic test of Junior College students. The object of concept advanced interpretive structural modeling (CAISM) is to provide individualized hierarchy structure of knowledge of examinees based on response patterns of tests. It shows that knowledge structures will be feasible for remedial instruction and this procedure will also useful for cognition diagnosis.

Abstract: Computer network is a product of modern computer technology and communications technologies. Computer network management technology refers to the initialization operation and monitor operation of computer networks in the active state. Computer network management technology function is to collect the related information in the network system. This article will mainly focus on computer network management technology and its application to start on.
