Mobile ad hoc networks are collection of wireless mobile nodes forming a temporary network without the aid of any established infrastructure. Security issues are more paramount in such networks even more so than in wired networks. Despite the existence of well-known security mechanisms, additional vulnerabilities and features pertinent to this new networking paradigm might render the traditional solutions...
Information in construction project has always been dispersed and scattered in every independent phase. It is always a challenge to integrate project lifecycle information in construction system management to improve productivity. Based on comparison of information lifecycle and construction project lifecycle, this paper presents an information lifecycle modeling to manage construction projects through...
The agent-oriented approach has emerged as a novel and popular paradigm for modern management information system analysis, design and implementation. In this paper, the authors concentrate on the design of a real application: SPAERIS (shipping pollution accident emergence reflecting information system), using AUML(agent Unified Modeling Language). Furthermore, we explored and discussed the strengths...
Defects of linear and circular models on industry agglomeration have been illustrated in this paper, with the conclusion that the defects lie in the improper prerequisite of the models, which will lead to false identification of the fundamental impetus of the phenomenon. A dynamic evolution model on industry agglomeration based on swarm intelligence is set up, followed with relevant computer simulation,...
Introduces the development and application research of load about air- conditioning based on BP neutral network. Connects some theory about BP neutral network and characters about bus air conditioning, and develops BP neutral networks for cooling load calculation of bus air conditioning. The results show the cooling load decrease 22.8 percent compare with steady calculation method. The BP neutral...
To assess quality fast and accurate, analyze the K-means clustering, point out that the main advantages of k-means algorithm are its simplicity and speed which allows it to run on large datasets .Introduce the method of particle swarm optimization, through calculation, point out that all the particles are likely to faster convergence on the optimal solution. According to the character of quality assessment...
Identifying database corresponding attributes in schema matching plays a key role in data integration in heterogeneous databases. Most of current approaches mainly use schema information of attribute. Little research has attempted to fully explore the use of data content. This paper introduces a novel schema matching algorithm based on data content, which has two-step process. First, through the analysis...
In recent years, the explicit semantic analysis (ESA) method has got a good performance in computing semantic relatedness (SR). However, ESA method has failed to consider the given context of the word-pair, and generates the same semantic concepts for one word in different word-pairs. It canpsilat exactly determine the intended sense of an ambiguous word. In this paper, we propose an improved method...
Based on the heterogeneous wireless sensor networks, MIMO_SEP scheme is proposed in this paper. When the node runs for cluster-head, the node with different energy would have different probability. At the same time cooperating nodes were designed which form virtual Multiple input multiple output with cluster head to transmit data. MIMO_SEP not only could better handle the heterogeneous energy capacities,...
This paper analyzes the importance and necessity of synergistic work of R&D teams, establishes incentive factors, mutual factors and supporting factors in the process of synergistic work and the structural equation model of relations among various R&D team atmospheres. On the basis of exploratory factor analysis, confirmatory factor analysis and full structure equation model analysis, the...
Ontology mapping created by end-users contains class hierarchy structure knowledge of the domain, and using that knowledge could produce new domainal ontology mapping. However, current systems have the following drawbacks: insufficient consideration of class hierarchy complexity, incomplete deletion inconsistent knowledge and inefficiency. Aiming at solving those problems, this paper proposes a new...
This paper reports our method on measuring data quality in data integration. Data integration is the problem of combining data residing at different sources, and providing the user with a unified view of these data. Data quality is crucial for operational data integration. We posit that data-integration need to handle the measure of data quality. So, measuring data quality in data integration is one...
Guided by the requirement changing of innovation, every country is frequently adjusting development strategy to reconstructing the information service system. This paper comprises the industrial information service organization and management mode with United States, EU, Japan, and Russia, and analyses the advantage and problems in Chinapsilas industrial information service system reform. Facing these...
Based on the statistics from 1998 to 2005 released by Henan Statistical Bureau in China, this paper applies the compensative GM (1, N) model to simulate the relationship between technical input and economic growth. In this paper, the parameters of the system are obtained via the principle of least square method. In the numerical experiment, the model simulates the GDP values of Henan province from...
The importance of non-government fundspsila engagement in public project is illuminated in this paper, and the defects of classical methodologies of cost and investment decomposition for public project among funds of various nature is elucidated. On analyzing the nature of decomposition, a model based on multi-player cooperative game is promoted for the solution, and further suggestions have been...
In this paper, a new method PRECGDT-CWT is advanced, using the standard DT-CWT filters of the (13-19) taps near orthogonal filters at level 1 together with the 14-tap Q-shift filters at levels not less than 2. We chose ten iterations of the conjugate gradient algorithm used with the preconditioned system search direction starting from a ward estimate. We also compare the results with alternative deconvolution...
