To improve manufacturing capability of national defense industry, the paper brings forward tools preparation problem by analyzing tools management business, and then discusses how to select appropriate tools preparation methods according to cost, time, quality and server. Further more, the key technology about manufacturing resources information integration technology based on XML,tools classification...
A major concern in wireless sensor networks is to maximize network lifetime while maintaining a high quality of service at each round, which includes target coverage and network connectivity. There are two competing objectives presented to determine where to place the sensor nodes, the coverage rate and the number of working nodes. And then a novel algorithm for selecting the optimal coverage set...
Open vehicle route problem of logistics distribution is the important step optimizing logistics distribution. According to the traditional genetic algorithm shortcomings of slowly convergent speed, weakly partial searching ability and easily premature, therefore, hybrid genetic algorithm is used to get the optimization solution, namely, use dualistic coding so as to simplify the problem and improve...
Genetic algorithm (GA), as a kind of important intelligence computing tool, is a wide research content in the academic circle and the application domain now. In this paper, for the mutation operation of GA, by combining with the essential feature, we establish a genetic algorithm based on schema mutation (denoted by SM-GA, for short). Further, we discuss the global convergence of CM-GA by using the...
The proliferation of online auctions has caused the increasing need to monitor and track multiple bids in multiple auctions. An autonomous agent was developed to work in a flexible and configurable heuristic decision making framework that can tackle the problem of bidding across multiple auctions that apply different protocols (English, Vickrey and Dutch) as a solution to the problem. This agent utilizes...
Ad hoc networks are characterized with frequent link failures and network topology change. These features result in a great challenge to transmit video over ad hoc networks. We propose a novel content-based layered multiple description coding scheme C-LMDC for robust video transmission over ad hoc networks. First determine the region of interest (ROI) of the video image before actual coding. Then...
JPEG2000 is the image compression standard which includes three core techniques: wavelet lifting scheme and EBCOT and MQ arithmetic coder. The EBCOT algorithm uses a Wavelet transform to generate the subband samples, which are quantized and coded. Normal Wavelet transforms fail to represent such functions effectively while Ridge functions are effective in representing functions that have discontinuities...
Naxi pictograph is the only still using hieroglyph all over the world, which does a positive role in the research for evolution history of human language. Through the analysis for the characteristics and information processing of Naxi pictograph, this paper proposes a transcription scheme of Naxi Pictograph input method from phonetic into primitives, and also optimizes this scheme. Based on Windows...
XML is a de-facto standard for exchanging and presenting information on the Web. However, XML data is also recognized as verbose since it heavily inflates the size of the data due to the repeated tags and structures. The data verbosity problem gives rise to many challenges of conventional query processing and data exchange. Compression techniques are the important way to overcome the verbosity problem...
