Today network intrusion detection and intrusion prevention system (NIDS/IPS) are considered as one of the hottest topics in computer security. On the other side firewalls have optimized several times and different types have been introduced. Today by integrating NIDS and firewall a new product comes to the market, which is called IPS. IPSs protect information systems from unauthorized access, damage...
With an ordinary style of twelve menpsilas seamless underwear as the target of study, of which made the same style, material and the different cylinder diameters, organization structures and knitting methods. The pressure and pressure sense of different positions in the upper body of seamless underwear were tested by young men of M body sizes under static and action state. The methods of objective...
Web service composition is used as subprocess in the workflow system. If the workflow can provide high reliability and constituency through transaction process technology, the composition of Web service and workflow will be the main solution to solve problem of e-business. Traditional transaction model lacks support for long-running transaction in application of Web service. From the angel of the...
Supplier's quality not only influences manufacture enterprise's achievement, but also determines the successful operation of entire supply chain. How to choose supplier scientifically and efficiently, and make stout supply chain system, have become a key point for the manufacture enterprise's decision-making day after day. Some methods have been proposed to select supplier such as neural network and...
Not each partner enterprise of virtual enterprise will share its private data with other enterprise, so there is a conflicting problem of data exchange in virtual enterprise. To solve the problem, a data exchange model of virtual enterprise is presented. In the model data exchange makes intersecting compromise on different objects.
Error elimination is very important in 3D measurement with ring-structured-light. A method has been proposed, which includes the following procedures. First, acquire ring-structured-light images and extract their stripe center. Second, find the base-circle center of the stripe center locus by curve fitting, using the least squares method. Subsequently unfold the stripe center locus along its base-circle...
For parallel operation of electric network it need to control the current to be in phase with the electric network voltage. This paper presents a control method of phase tracking based on artificial neural network. After comparing the simulation results between BP network and RBF network, it takes the algorithm of RBF network into phase locked loop. It takes the electric network voltage as the expected...
This paper proposes a new approach for tackling the multi-attribute decision making problems under uncertainty or the decision makerpsilas imprecise judgment environment. In this paper fuzzy grey relational analysis for multi-attribute decision making is extended to fuzzy environment. A new algorithm for fuzzy grey relational analysis for the evaluation of information technology outsourcing service...
The massive amount of visual inputs could easily go beyond the systempsilas computational limit. Visual attention provides an efficient way to discard the trivial inputs and achieve good performance. In this paper we develop a unified and consistent theoretical framework for the visual attention and inference with Bayesian decision theory. A visual attention scheme is simulated with an artificial...
In order to show the performances between different speech recognition engines in Chinese Mandarin recognition, experiments are designed in this paper to compare the recognition performances on Chinese Mandarin between HTK and Sphinx, which are the two most popular open source automatic speech recognition systems. Both isolated words recognition and continuous sentences recognition were investigated...
To utilize the separate advantage of the Synthetic Aperture Radar (SAR) and infrared images, in this paper, a fusion method based on the nonsubsampled contourlet transform is proposed for SAR and infrared image fusion. Simulation experiments show that this method can yield fusion image with better visual quality than discrete wavelet transform and the obtained fusion image can preserve much information...
According to the research needs in speech synthesis and speech recognition applications, this paper analysis the acoustic features of semivowel in Uyghur language from the view of experimental phonetics that some acoustic parameters such as formant, pitch, durations were measured, and finally verified the fact by means of experimental phonetics analysis method that the semivowels have the typical...
In this paper based on the needs of speech application research such as speech synthesis and speech recognition, combined the characteristics of the Uyghur language, for the first time, established the "Uyghur speech acoustic parameters database" which includes common sentences, words, syllables and phonemes and their acoustic parameters. And the details of key technologies in the procedures...
Clothing industry is an important exporting and earning foreign exchange of China. There are many clothing production enterprises in China. These enterprises' management level and production technique directly decide the future trend of Chinese clothing exporting. This paper, according to the related theories and practical situations of enterprises, develops a set of production management system for...
With the severer and severer market competition, more and more enterprises pay attention to informatization construction, and even some domestic small and middle enterprises (SME) also take the management of suppliers and customers into their informatization construction system. However, when enhancing exterior informatization construction, enterprises always ignore their inventory management and...
As rapid development of economy and people's gradually great attention to energy environmental problems, more and more researchers have started researching the relationship between economy, energy and environment, we urgently need methods and models to solve the disagreement between them, and so 3E-based forecast and early-warning models began to emerge, and develop towards high-precision and comprehensive...
This paper mainly research the probabilistic planning problems based on the creating or destroying objects. Firstly, a new definition on mutex inference is given, because the objects can be created or destroyed and the actions are uncertainty. We adopt the thought of transforming object into proposition. Secondly, we propose a new concept of concurrent action set and give the algorithm for creating...
Based on bin packing problem algorithm, a revised best fit decreasing algorithm for container shippsilas stowage problem was proposed. The simulation result indicates that the performance of the proposed algorithm is sound.
The paper discussed the optimum uses of water resource in a city based on social-economic-environmental (SEE) complex system by applying system dynamic model, which fully considered the interactions and interrelations amongst each element in the SEE complex system. The SD model can be used to estimate the overall development trends based on the current development status, and then relevant information...
Campus networkpsilas Internet accessing traffic is complicated, non-linear and periodical. Our goal is to give out a engineering approach to prediction of network traffic based time-series analysis model (EPTS) for campus exit-link. In our EPTS with rate-limiting, we configure rate limit based interface, then use time-series decomposed model, give out the linear trend component, periodical component,...
