To avoid it happening that the correctness of created model and developed simulation software on calculating the response time of ABS (anti-lock brake system) is partially verified by the experiment result, based on the structure of a typical ABS, the calculation models of the controllable characteristic and mechanical characteristic were created, and the simulation calculation software was developed...
Sudoku, a simple and fun game of logic, has been used for steganography to conceal messages into a digital image recently. Chang et al. adapted the idea of smallest Manhattan distance, embedding secret messages into the neighbors of the located element according to a given Sudoku solution. Hong et al. improved Chang et al.psilas technique by introducing additional set of candidate elements to reduce...
The precision of tile image edge detection has great influence on the dimension detection and defect detection of tile. A parallel model of Back-Propagation (BP) neural network for edge detection of binary image was proposed in this paper, and it was applied to edge detection of gray image. It solved the problem that the convergence speed was too slow to meet the need of training if the BP neural...
Material service safety is very important for public security. Researchers and engineers have devoted themselves to establishing models for material service behavior. Utilizing these models to predict material service behavior and assess service safety is an efficient and idealized way. However, material service behavior is quite complicated. Only simple material behavior models have been established...
Performance predictions from wireless networking laboratory experiments seem to dismatch what is really deployed. To generate realistic traffic is one of the major factors hampering researcherspsila ability to make reliable forecasts. This paper reports on the results of a multiscale analysis of traffic traces captured at an infrastructure 802.11g wireless network. The analyzed traffic is characterized...
Web topic is the theme indicated by Web pages. Some methods have been proposed to represent Web topic based on text mining. However, these methods canpsilat denote multimedia contents on Web page, such as images, audios, videos and so on. Consequently, text-based methods can't represent Web topic exactly because most Web pages consist of many multimedia contents. This paper proposes a new approach,...
For the characteristic of All-IP networks, the impact of higher mobility of mobile node and higher overlap region of mobile agent on smoother handover was considered. For the existed questions of longer delay, packets loss, and easier failure at handover, the pre-handover in the overlap region based on HMIPv6 protocol and overlap computation was proposed. Instead of matching prefix of broadcasting...
This paper introduces a mathematical model for chunk parsing of Chinese sentence. Automatic identification of Chinese chunk is implemented by using BP network. Based on BP network, some new research methods and experiments on the input features are proposed and performed in this paper. The experimental results show that the full use of the known information can improve the accuracy of Chinese chunk...
On the basis of the mathematic model for the optimizing of distribution routing of farm produce, this article presents genetic algorithm (GA) to solving this problem. This method can find the optimal or nearly optimal solution to the vehicle routing effectively, which is proved by an experiment provided by this paper.
With the latest semantic annotation specification SAWSDL provided by W3C, web service components were annotated, and annotation process and method were discussed in detail. At the same time, a framework for web services matching and composition was present and its prototype was developed. Service matching algorithms, which were integrated in a service template, were stressed from aspects of function...
A novel parallel memory accessing for decimation-in-time twin butterfly parallel architecture radix-4 FFT algorithm is proposed, which is based on "in-place" principle and allows conflict-free access to the 8 operands needed for calculation of the twin butterfly distributed over 8 parallel memory modules. Data and twiddle factor address generation algorithm and store scheme are described...
