Web application testing is concerned with numerous and complicated testing objects, methods and processes. So a testing framework fitting for the properties of Web application is needed to guide and organize all the testing tasks. Based on the analysis for Web application characters and traditional software testing process, the process for Web application testing is modeled, which describes a series of testing flows such as the testing requirement analysis, test cases generation and selection, testing execution, and testing results analysis and measurement. Furthermore, the realization techniques are also investigated so as to integrate each testing step and implement the whole testing process harmoniously and effectively. Thus the framework is suitable for the Internet environment and can guide the Web application testing actively and availably.

This paper represents a multi-user interactive virtualpurchasing environment realized by technologies suchas multi-agent, VRML, JAVA3D, XML and thecomputer network. In this environment, there is asymbol with mood for every customer, which cancommunicate freely with symbol of other customers,commodities in the shopping mall and the intelligentagent. In the meantime, a virtual purchasing guider isdesigned to communicate with different symbols ofcustomers in different manners. This virtual guider isable to patrol in this virtual 3D environment along thepath planned by itself. Customers may have dynamiccommunication with other purchasers through thevirtual guider or operate interactively on all kinds ofcommodities. This system simulates the wholepurchasing process including window-shopping,choosing and paying for the items. Such comprehensivesimulation is a new-brand E-business system thatmakes the customer feels like they are personally on thescene.

Dynamic optimisation problems are becoming increasingly important; meanwhile, progress in optimisation techniques and in computational resources are permitting the development of effective systems for dynamic optimisation, resulting in a need for objective methods to evaluate and compare different techniques. The search for effective techniques may be seen as a multi-objective problem, trading off time complexity against effectiveness; hence benchmarks must be able to compare techniques across the Pareto front, not merely at a single point. We propose benchmarks for the dynamic travelling salesman problem, adapted from the CHN-144 benchmark of 144 Chinese cities for the static travelling salesman problem. We provide an example of the use of the benchmark, and illustrate the information that can be gleaned from analysis of the algorithm performance on the benchmarks.

The accuracy of concrete strength inspection has a great influence on the safety evaluation of the building. In order to increase the accuracy, Fuzzy Neural Network (FNN) was built up to evaluate concrete stmngth: It takes full advantage of the characteristics of the common concrete testing methods: drill and rebound, and the abilities of FNN including automatic learning, generation and fuzzy logic inference. The experiment shows that the max relative error of the predicted results is 1.12%, which is satisfied with the requirements of the engineering. The method effieieatly maps the complex non-linear relationship between the drill values and the rebound values, and provides a efficient way for the concrete strength inspection and evaluation.

A METHOD TO APPROACH OPTIMAL RESTORATION IN IMAGE RESTORATION PROBLEMS WITHOUT NOISE ENERGY INFORMATION

引用

Acta Mathematica Scientia 2003年第4期23卷 512-520页

作者：曾三友丁立新康立山 State Key Laboratory of Software Engineering Wuhan University Wuhan 430072 China Deptartment of Computer Science Zhuzhou Institute of Technology Zhuzhou 402008 China State Key Laboratory of Software Engineering Wuhan University Wuhan 430072 China

This paper proposes a new image restoration technique, in which the resulting regularized image approximates the optimal solution steadily. The affect of the regular-ization operator and parameter on the lower band and upper band energy of the residue of the regularized image is theoretically analyzed by employing wavelet transform. This paper shows that regularization operator should generally be lowstop and highpass. So this paper chooses a lowstop and highpass operator as regularization operator, and construct an optimization model which minimizes the mean squares residue of regularized solution to determine regularization parameter. Although the model is random, on the condition of this paper, it can be solved and yields regularization parameter and regularized solution. Otherwise, the technique has a mechanism to predict noise energy. So, without noise information, it can also work and yield good restoration results.

A fast algorithm is proposed to solve a kind of high complexity multi-objective problems in this paper. It takes advantages of both the orthogonal design method to search evenly, and the statistical optimal method to speed up the computation. It is very suitable for solving high complexity problems, and quickly yields solutions which converge to the Pareto-optimal set with high precision and uniform distribution. Some complicated multi-objective problems are solved by the algorithm and the results show that the algorithm is not only fast but also superior to other MOGAS and MOEAs, such as the currently efficient algorithm SPEA, in terms of the precision, quantity and distribution of solutions.

The linear model of market value functions is a new method for direct marketing. Just like other methods in direct marketing, attribute reduction is very important to deal with large databases. We apply the algorithm of attribute reduction, which is based on the combination of rough set theory with the boosting algorithm, to the linear model of market value functions. Experimental results compared with the ELSA/ANN model show that the proposed algorithms can be used effectively in the linear model of market value functions. © 2003 IEEE.

In order to construct a secure network, attack and intrusion mode of intruders are analyzed for improving the capability of IDS and firewall systems. This paper presents a method for constructing a network intrusion and attack detection system on Honeynet, which is a true network that is constructed for the purpose of gathering information of intruders and attackers. Analyzing these data with data mining algorithm can work our attack modes, in this paper, we propose some method for mining patterns on various data from firewall records and log server in Honeynet, and the result can be in various forms such as associated rules of historic data or certain data structures required by IDS and firewall systems.
