Intrusion Detection Systems (IDSs) have become an efficient defense tool against network attacks since they allow network administrator to detect policy violations. However, traditional IDs are vulnerable to original and novel malicious attacks. Also, it is very inefficient to analyze from a large amount volume data such as possibility logs. In addition, there are high false positives and false negatives...
With the development of computer and Internet, it is easy to get related information. For the catalytic cracking unit of oil refining industry, although there is a flood of information recorded data, the changes in yield of the product caused by the changes of production of raw materials and run-time still need to rely on the experience and learn from a running instance, so Data Mining has a unique...
With the continued expansion of network resources and the rapid change of old and new information, the traditional information retrieval is difficult to adapt to the need of management of mass electronic data. It is a very important aspect of how to locate the information you want conveniently and accurately and improve the efficiency of search engines.
Fuzzy pattern recognition is an application of fuzzy mathematic theory in the field of pattern recognition. Theoretic basis of this method is fuzzy multiple-valued logic whose truth-value is determined depending on membership function. Now, however, the membership function definition of fuzzy set has not formed uniform method and general format yet. Determination of membership function is mainly affected...
This paper addresses the prediction for moving objects when the motions of the objects having some associations. In the real world, the moving objects often have some associations with other objects. Unfortunately, existing techniques for moving objects prediction are designed for single independent object, and ignore the associations between the moving objects. This paper firstly defines an association...
This paper introduces the new intelligence technology in the transformer fault diagnosis - artificial intelligence system (TFDAI). An artificial intelligence system design includes selection of input, network topology, synaptic connection weight, and output. TFDAI module structure, data processing and diagnostic techniques are described in detail. It consists of expert system (ES) and artificial neural...
Spread spectrum communication system with high bit rate, has bad performance of acquisition sensitivity, since the coherent integration time is short. The bad performance can be improved by the method of non-coherent integration processing after coherent integration. But in low SNR environment, the performance is not satisfying because of the large SNR loss of noncoherent integration. This paper describes...
In a highly competitive market, technical innovation and product differentiation are becoming effective ways to avoid cut-throat competition. In this paper, the pricing game model is first established between different brand's standard and innovative products of the same company, then it is discussed that the influence of the degree of product differentiation on equilibrium price. Based on some numerical...
Smooth logistics system contributes a lot to the success of chain operators, which is exerting ever increasing influence on China's economic development. This paper first analyzed the predominance of chain operators and then proceeded to the discussion of network implementation into logistics. Based on the reference of logistics advanced theory and the study of logistics chain management system, mathematical...
Supported by one-sided samples information alone, one-class classification problems are more difficult to deal with than those of the traditional two-class or multi-class classification in the sense of parameters optimization. Support vector data description (SVDD) has become one of the most popular kernel learning methods for solving one-class classification problems, while RBF kernel is the most...
A deinterleaving algorithm of radar signal based on DSP is presented in this paper, which is according to the structure of the deinterleaving system, characteristics of PDW (pulse descriptor word) and histogram method. The threshold determination, accumulation of PRI (pulse repetition interval) and others in the algorithm applied in different fields are introduced in detail. The experimental results...
Nowadays, the management style of most distribution networks in rural area is supported by the technology of Computer Management System based on relational database. It doesn't meet the requirement of the increasingly complex situation. GIS technology which develops gradually and is widely used in late years can manage and analysis the spatial information efficaciously. This paper introduces the Software...
The objective of this study is to construct an easy operational model to evaluate the performance of the reverse logistics management. To fulfill this mission, the main contributions were made as following: a) Defining the indicators of each factors related with performance of the RL management. CSFs (critical success factors) method was employed in this phase. b) Arranging the indicators into an...
An experimental study on the conversion of NO in the NO/O2/N2 system has been carried out using Dielectric Barrier Discharge (DBD) Plasma at atmospheric pressure. The emphases are on energy consumption and the efficiency for NO conversion in the system. By measuring the concentration of NO and NO2 as a function of specific energy density (SED), it is possible to determine the energy consumption for...
Based on analytical hierarchy process (AHP), the evaluation index system of 10 kV distribution system is put forward in this paper scientifically and objectively, which is combined with the practical distribution system model. The relative weights of index hierarchy are also developed by using synthetically grading method. With the application of the index system, this paper has given overall analysis...
Because traditional wavelet transformation is decimals, which inevitably introduce transformation error in image watermarking. A digital watermarking algorithm is presented based on the mean quantification of the second generation wavelet. After a host image is decomposed by the lifting wavelet, its low frequency coefficients is used as performing the mean and quantification processes, and embedding...
A robust position controller with variable structure control (VSC) and dynamic recurrent fuzzy wavelet network (DRFWN) technique for permanent magnet synchronous motor (PMSM) is presented in this paper. Based on the VSC method, the closed-loop system can system dynamics with an invariance property to uncertainties. However, the sliding controller based the assumption of known uncertainty bounds often...
