In education field, presentation tools like PowerPoint are widely used and play important role in creating learning content. But the file formats of those presentation tools like ppt do not support web page format which is suitable for Web publishing. Those presentation tools file formats are usually need further format converting process, like converting ppt files to web page files or to swf files. To solve the problem, the paper designs and implements a simple presentation tool, and the file format is based on Web pages. The file of the simple presentation tool is composed of several web pages based on vml supported by IE, and each web page is relative to a slide, that is mean editing slide is editing web page. So the file generated by the simple presentation tool does not need further file format converting, more suitable for web content publishing. The paper introduces the architecture of the simple presentation tool, and its basic functions including textbox edit, picture edit, graphic edit, slide edit.

A new access algorithm in cognitive radio systems is proposed inthis paper, which can decrease primary users' access delay effectively and guarantee the access throughput fairness among primary users and secondary users. In the time domain, primary users apply 1-persisten access policy and secondary users apply exponential backoff retransmission policy; while in the frequency domain primary users select several suitable subcarriers as access channels and secondary users select only the subcarrier with the least interference temperature as access channel. Simulations confirm the perfect performance of the proposed algorithm.

A novel endless polarization control algorithm based on simulated annealing (SA) algorithm is proposed. The application of the SA algorithm in a fast feedback polarization controller (PC) constructed by four electro-optic ceramic variable waveplates for the continuous conversion of the state of polarization (SOP) is presented. The experiment results show that the fluctuation of the light intensity in the desired output SOP is less than 2 % for a random input SOP. It is demonstrated that, this SA-based PC can run reset-freely and the response time is less than 400mus.

An approximate strategy is designed for the static data management in geometric network. If all parameters is given, a constant approximation ratio is achieved. Here, we suppose that the link cost don't satisfy triangle inequality, but the ratio of the maximum link cost to the minimum value is known.

Mobile ad hoc networks possess the following features: open transmission medium, dynamic topology structure, acentric management and distributed cooperation, and so on. Therefore, Ad Hoc Networks have high practical value, while at the same time it is difficult for which to guarantee the routing security, which is the most important component of the entire network's security, it is also a difficult problem to be solved completely. This paper analyzes the working principle of the AODV routing protocol, discusses the protocol's main potential safety problems - the problem of the black hole, proposes an solution based on the test of the destination node according to the significant vulnerabilities of some typical solutions already in existence, which not only solve the problem of the black hole effectively, but also eliminate the significant vulnerabilities existing in the original propose fundamentally.

In this paper, a LS-SVM model based RLG's scale factor temperature data modeling method is studied. Using traditional least square linear model to modeling nonlinear ring laser gyro scale factor test data has its intrinsic shortcoming, and sometimes it is difficult to meet the application requirements. Recently, nonlinear function approximation based modeling methods such as the BP networks are introduced to modeling the temperature data. But in the BP networks will suffer the problem of overfitting and the existence of many local minima. To avoid these shortcomings the LS-SVM is used to modeling the scale factor temperature data. Base on the analysis of the test scale factor data, the scale factor test data is modeled as the function of the temperature and its increment, and LS-SVM model is employed to estimate the nonlinear function. The simulation results show that the LS-SVM model can approach scale factor data accurately, and its precision is much higher than the least square model. The mean squared deviation of LS-SVM model is smaller than 0.51times10-6("/pulse). Base on considerately designed test procedure and large numbers of experimental data, a practical temperature model can be established.

The paper proposes a concept segmentation method to extract meta-knowledge from the multi-source knowledge base. We improve the traditional structure-based extracting method by using the concept hierarchical partition. The concept and concept relationship can be described with ontology model, which can discover the semantic relationship between concepts. Then a self-learning of meta-knowledge model is set up which can optimize the meta-knowledge description. Finally an empirical study is carried out by implementing the meta-knowledge extraction process from multi-source knowledge bass for educational resources.

In the classical rough set theory, the use of the indiscernibility relation which is used in the complete information systems may be too rigid in some real situations. In order to process incomplete data, the indiscernibility relation needs to be extended. In this paper, after discussing the basic concepts and current research on the characteristic relation under incomplete data, a modified characteristic relation that is dependent on the number of missing values with respect to the number of the whole defined attributes for each object is introduced; the lower and upper approximation defined on this relation are proposed as well. Furthermore, we present some properties of this modified characteristic relation. The experiments show that this relation works effectively in incomplete information and generates object classification reasonably. This electronic document is a "live" template. The various components of your paper [title, text, heads, etc.] are already defined on the style sheet, as illustrated by the portions given in this document.
