摘要：
In order to effectively reduce the dependence on the experimental environment and make the teaching process more interesting, a method of virtual interactive experiment based on data glove is proposed in this paper. First, on the basis of analysis the structure of human hand, a virtual hand model with the joints as nodes is created. Then the definition of motion is discussed and a mapping between motions and actions is established. Finally, HCI method based on data glove is realized according to the motion restriction and successfully applied to the virtual experiment system for physics.

摘要：
Optimal energy-efficient multicast tree in WANETs is built. We propose the Energy Distance Ratio (EDR) metric based on the characteristic of energy consumption of nodes for multicast communication in WANETs and introduce this metric into ad hoc network graph model to improve this model to be energy-aware. Simulation result shows that improved ad hoc network graph model has much better performance in extending the lifetime of multicast trees than that of the former model. Our improved ad hoe network graph model is a stronger basis for the design of an energy-efficient multicast routing protocol in WANETs.

摘要：
With the rapid development of geographic information system (GIS), computer aided design (CAD), mobile computing and multimedia databases, spatiotemporal databases have been the focus of considerable research activities over a significant period. It becomes an enabling technology for important applications such as land use, real estate, transportation, environmental information systems, energy resource et al. In this paper we address research issues in spatiotemporal databases. We first proposed an integrated spatiotemporal data model, and then we provided novel threetier architecture for implementation where Meta tables to handle spatiotemporal data were extended. Finally, experiments confirm the effectiveness of our techniques under realistic settings.

摘要：
In this paper we present an approach to mining domain-dependent ontologies using term extraction and relationship discovery technology. There are two main innovations in our approach. One is extracting terms using log-likelihood ratio, which is based on the contrastive probability of term occurrence in domain corpus and background corpus. The other is fusing together information from multiple knowledge sources as, evidences for discovering particular semantic relationships among terms. In the experiment, we also improve the traditional k-mediods algorithm for multi-level clustering. We have applied our approach to produce an ontology for the domain of computer science and obtained promising results. http://www.aclweb.org/anthology/Y06-1020

摘要：
This paper first introduces the test model of an extended finite state machine and The Protocol Specification Language. Then it analyzes the test suite generation method which integrates the control-flow and data-flow. The method is based on EFSM model. Last it introduces the construction of test system. Through this method it cans more highly effective produce the protocol test suite.

摘要：
Geometric attacks are among the most challenging problems in present day watermarking. Such attacks are very simple to implement yet they can defeat most of the existing watermarking algorithms without causing serious perceptual image distortion. In this research, a novel method to estimate the geometric manipulation is reported. The point pattern matching measure is computed for estimating geometric manipulation. The reference point patterns (i.e., a triple) are computed from feature ellipse of the original image. The proposed scheme does not require the original image because reference triple information of the original image has been contained in the secret key. Novel algorithm has been proved its robustness to geometric attacks through experiments results. (c) 2005 Elsevier Inc. All rights reserved.

摘要：
This paper gives a mathematical description of the undirected network capacity definitions and theorems of computing capacities towards the network. Prove of the theorem correctness is also given. According to them, the paper proposes an algorithm of computing the undirected network capacities based on spanning tree and even an advanced optimization algorithm. In addition, it discusses network capacity expansion problems with constraints. And then, the optimization algorithm in the scenario of undirected network with limited costs is outlined, whose feasibility and process are illustrated via examples.
