There are low bit and high bit hiding algorithms in the spatial domain. The paper proposes a new algorithm. First, divide the cover image into three-pixel blocks. Then, use Arnold transformation to scramble the secret image. Eventually, modify the pixel values to hiding information according to the corresponding mode of size relations and numbers. The experimental results show that the algorithm realizes...
For reasoning with uncertain knowledge causal semantics analysis is investigated to propose logical rules, which can represent multi-level semantic knowledge of the relationship between the data and information implicated.These rules constitutes several tree structures named decision forest, the number of trees and stopping criteria can be set automatically. Empirical studies on a set of natural domains...
Along with increasing credit cards and growing trade volume in China, credit card fraud rises sharply. How to enhance the detection and prevention of credit card fraud becomes the focus of risk control of banks. This paper proposes a credit card fraud detection model using outlier detection based on distance sum according to the infrequency and unconventionality of fraud in credit card transaction...
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.
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...
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...
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...
The multidepot vehicle routing problem with interdepot routes (MDVRPI) is an extension to the classical vehicle routing problem (VRP); it is the major research topics in the supply chain management field. It is an extension of the multidepot vehicle routing problem in which vehicles may be replenished at intermediate depots along their route. In this paper, we propose a heuristic combining the adaptative...
Neural network is a technology for intelligent transportation system and it is important in vehicle type recognition. However, traditional vehicle type recognition method always utilize BP network. A new vehicle type recognition based on radial basic function neural network was proposed. Also discussed are the problem of feature of vehicle feature vector, the problem of normalization of the image-size,...
Vehicle type automatic recognition is of great important today in intelligent transportation system. And neural network is often applied to recognize the vehicle type. However, the network can be very complex and therefore difficult to be trained. In order to cope with such issues, a new developed vehicle type recognition method based on contour feature is presented in this study. It is applied to...
The traditional three-dimensional object recognition method based on hypothesise and test need to solve the coordinate transformation matrix from scene to model through a group of non-linear equations. Therefore, it has a very high complexity. This paper presents a man-made object recognition method based on the geometry feature of line segments characteristics, and disperses the overall coordinate...
In this paper, an algorithm using point feature and intensity feature combined with the Artificial Immune algorithm is presented. First, the feature points of the two images are extracted by Harris corner detector to reduce the amount of computation. Then, the mutual information (MI) is used to be the similarity measure for MI algorithm based on intensity has excellent robustness and accuracy. Finally,...
With the development and advancement of reverse logistics concepts and practice, the evaluation and selection of vendors or partners for the specific function of reverse logistics support becomes more important. This paper firstly analyses the framework of selecting a third-party reverse logistics provider. Next, this paper presents a set of evaluation index system for choosing a third-party reverse...
A novel gene regulatory network model via the fuzzy logic is proposed. Fuzzy logic can effectively model gene regulation and interaction to accurately reflect the underlying biology. By judging genes expression level on the fuzzy rule, Fuzzy Boolean network (FBN) makes it possible to handle simultaneously the randomness and fuzziness of biological phenomena.
This paper states the necessity of establishing the economic evaluation system for safety resources in traffic enterprises systematically. The author gives the connotations of the proposed new economic evaluation system in traffic enterprises. The proposed evaluation system for safety resources can be used in all units with possible traffic accidents for estimating and reflecting the economic effectiveness...
The advance of image capture device and the popularity of the Internet have made the World Wide Web the biggest and most diverse repository of images. How to retrieve images fast and accurately from the WWW has become an urgent problem to be solved. Although many commercial Web image search engine has come forth, the precision is not satisfying for the reason that the text in the pages which they...
When Blog comes to the world, how to use Blog in education and instructions well has been one of the interesting studies among academic field increasingly. In this paper, by reading great material and communicating with the teachers in Rizhao open-up areal, it discussed the applications of Blog in education and teaching from sharing resources and communication of teachers, students and studentspsila...
