摘要：
These days, Web services have emerged as a promising technology, and may be used in the field of collaborative design. In this paper, we examine Web services as both a XML-based approach and a service-driven approach to collaborative design. Since Web services are a Service-Oriented Architecture (SOA) more than a set of technologies, it could be used not only at the technology level, but also at the SOA level, which may be more appropriate recur to the concept of Peer-to-Peer. Correspondingly, two prototypes are illustrated for further demonstration, and a possible scenario of the latter one is provided as a reference. A preliminary attempt to add semantics to services is also presented to facilitate the interoperability of Web services-based collaborative design.
摘要：
The availability of micro-sensors and low-power wireless communications enable the deployment of distributed sensor networks-for a wide range of applications. Considering the great potential of distributed wireless sensor networks in civil domains, this paper gives an idea about the application of wireless sensor networks in campus and analyzes the benefits that the sensor networks bring. Taking the Central China Normal University for example, we consider the specialty of campus and design the model of the campus sensor network in detail, which includes indoor and outdoor placement of sensor nodes. In addition, based on the placement an improved OPTIMUM-COV algorithm that applies in campus in the design was introduced. The aim is to achieve anticipant request of coverage by laying as less sensors as possible. At last it gives the simulation results and statistical data. The results show our design is feasible.

摘要：
Since the task scheduling in grid computing faces a NP-hard problem, it leads very difficult to validate the methods of task scheduling .This paper combined with the advantages of two evaluative algorithms: genetic algorithm and simulated annealing, brings forward an hybrid evaluative algorithm and applied to solve task scheduling problem in grid computing. From the analysis and experiment result, it is concluded that this algorithm is superior to genetic algorithm and simulated annealing.

摘要：
We consider scheduling and resource allocation for the downlink of an OFDM-based wireless network. During each time-slot the scheduling and resource allocation problem involves selecting a subset of users for transmission, determining the assignment of available sub-carriers to selected users, and for each sub-carrier determining the transmission power and the coding and modulation scheme used In this paper, we propose a heuristic genetic scheduling algorithm to maximize system throughput while providing a level of fairness among users for non-real-time data traffic in the downlink of a multi-user OFDM system. We first formulate the resource allocation problem for rate, power, and sub-carrier allocation as an integer program in the context of a utility-based scheduling. Next, we present a heuristic genetic algorithm for the problem. Through the simulation, we show that the proposed scheme performs better than other schemes in terms of both system throughput and fairness among users.

摘要：
As the Internet continues to grow, the tasks of configuration management for IP network devices are becoming more and more difficult. Over the past few years, much effort has been given to improve the deficiency of SNMP in the configuration management scope, hut only few have succeeded to be standardized, the famous one of which is Netconf developed by the IETF. Even the Netconf is still far from its aim to implement, the automation of the network configuration. These days, ontology has become a promising technology and it seems that it may be used in the intelligent configuration management scope. This paper first discusses the application of ontology and three related languages (including OWL, SWRL and OWL-S) to intelligentize configuration management. A common ontology-based intelligent configuration management model for IP network devices is then presented in the paper. To check the feasibility of this model, the paper also provides a possible scenario.

摘要：
Many application domains such as web page classification suffer from not having enough labeled training examples for learning. However, unlabeled training examples are readily available but labeled ones are fairly expensive to obtain. As a result, there has been a great deal of work in resent years on semi-supervised learning. This paper proposes a graph-based semi-supervised learning algorithm that is applied to the web page classification. Our algorithm uses a similarity measure between web pages to construct a K-Nearest Neighbor graph. Labeled and unlabeled web pages are represented as nodes in the weighted graph, with edge weights encoding the similarity between the web pages. In order to use unlabeled data to help classification and get higher accuracy, edge weights of the graph are computed through combining weighting schemes and link information of web pages. The learning problem is then formulated in terms of label propagation in the graph. By using probabilistic matrix methods and belief propagation, the labeled nodes push out labels through unlabeled nodes. Our preliminary experiments on the WebKB dataset show that the algorithm in this paper can effectively exploit unlabeled data in addition to labeled ones to get higher accuracy of web page classification.

摘要：
With the development of attacking technologies, the representations of security events become more and more complex, and the system security situation can't be detected or judged by some single security. In this paper, we put the theory and practical of neural network-based multi-sensor information fusion technology into security management for further study and put emphasis up on network security events fusion to optimize and improve the source events management and policy coordination in security management. We present a security management framework using neural network-based information fusion technology, and give an experimental environment to prove that the framework can provide believable security events and the output estimation for security management platform; it can serve as a reference for the response of network security events, so as to improve the response speed effectively.

摘要：
In wireless sensor networks, composed of a large number of mainly static nodes with highly constrained energy resources and special application environment, the design of routing protocol often encounters more difficulty. Though some efficient routing protocols have been proposed in the past time, there isn't ideal mechanism of the routing update exactly. On the basis of analyzing of some existing route repair methods, a new sensor network route repair approach has been proposed by utilizing the sequence of the sink node and information of old route. Also the implement and the performance evaluation of this algorithm compared to the existing routing protocols are presented.

摘要：
How to improve the rankings of the relevant documents plays a key role in information retrieval. In this paper, a re-ranking approach based on topic words pair is proposed to improve precision while recall is preserved. The topic word pairs contain two correlated words, one of which is the original query word and the other come from the documents. The selection is based on Probabilistic Latent Semantic Indexing (PLSI). Then,the distribution of the Word pairs is used to re-rank documents. Results show a 53.6% and 56.8% improvement compare to the initial retrieval without any re-ranking, or query expansion on NTCIR-5 document collection for SLIR. http://aclweb.org/anthology/Y06-1031
