Context based recognition system, which can improve the accuracy of scene recognition if robots cannot obtain adequate recognition features in the camera, has attracted researchers recently. However, there are few researches which focus on part-whole supplement system based on context which can describe the scene using detail parts in the scene and also reduce the ambiguity of each detail part using...
To apply FPGA automation system to the flow adjustment of traditional metering pump is a more advanced study theme. Using computer, FPGA technology and combined modern sensor technology, a FPGA -based metering pump motor rotation rate controlled system was developed. It can control the flow of the metering pump successfully. It is proved that it not only has simplified the flow control operation and...
As an effective global search method, genetic algorithm has obvious advantages. But it usually has problems of premature convergence and local optimum in practical application. According to this, a new algorithm with improved selection, crossover and mutation is proposed. Through the simulation experiments, the improved algorithm shows its faster convergence and better stability. It is valid which...
Collision detection algorithm based on bounding box is an important algorithm of collision detection.The principle and effectiveness of axis-aligned bounding boxes(AABB)method, oriented bounding box method(OBB), discrete orientation polytopes (k-DOP)method were discussed in detail. The results of analysis prove that the simpleness of bounding box is in contradiction with the compactness of wrapped...
Segmentation and Part of Speech tagging of Oracle inscriptions are the premise and foundation for establishment of Oracle Corpus and computer-aided Oracle textual research and explication. As for segmentation of Oracle inscriptions, this paper proposes a positive match cut algorithm, which adopts language analyzer based on Lucene and supplemented with Oracle Dictionary. Then the segmented words by...
Frequency estimation is a useful technology for analyzing oscillatory phenomena. In these days, there is a demand for rapid and highly accurate frequency estimator. Though various frequency estimation methods have been proposed, most of them can not respond to the demand. An algebraic approach is succeeded in achieving the demand but it requires a lot of multiple integrations due to eliminating differential...
The world have witnessed an explosive growth in the information available on the World Wide Web (WWW) over the last decade and people use it than ever before. With the everyday increasing importance of privacy, security, and wise use of computational resources, the corresponding technologies are increasingly being faced with the problem of file type detection. True identification of computer file...
Aim of the manuscript is to present an integrated web-based platform which is able to assess a person's risk to develop Cardiovascular Disease (CVD) using the Body Mass Index (BMI) as independent risk factor based on genetic and lifestyle information and in parallel to provide personalized advice in order to reduce this risk. A subject fills out a web available questionnaire regarding his/her lifestyle...
Aiming at improving the efficiency of the objects ranking in ordered information system, the problem of sorting is researched in this paper. Then a novel framework based on rough set theory is proposed, the key idea of which is compressing the original data by attribute and value reduction. In the new approach the information table is simplified firstly by rough set theory after transforming an ordered...
