Both in daily classrooms and at enterprises conferences, timely feedback from the audience and students are very important for chairmen or teachers. This will improve chairmen's or teachers' working and teaching efficiency in the interaction, because they can promptly know their audience's ideas and comprehension about the contents which they are describing. In this paper, we present software that...
A 100-kV/60-A high-voltage power supply (HVPS) is developed to supply the auxiliary heating system for a J-TEXT tokamak. This power supply is based on pulse step modulation (PSM) technology and consists of 144 switch modules. To fulfill the isolation, control, and protection requirements, a control system based on the PCI extensions for instrumentation is designed with the PSM technology for the HVPS...
The set covering question is NP-Hard problem on optimized combination. In this paper, we presented Simplifying and Selecting-Excellence Algorithm (SSE) based on the strategy. The main ideas of it: Before a most possible set was chosen, the set covering problem was simplified and the necessary sets were chosen. The obtained solution is more approximate to the exact solution than greedy algorithm. The...
This paper addresses the problem of establishing hybrid instrument tracking using optical and electromagnetic devices for therapeutic application. Concretely, the hybrid tracking method is a video tracking system based on tracking a uniquely designed marker, and present a scenario where the electromagnetic system can be combined with the video based system to obtain a cost-effective system. A developed...
In recent years, the problem of privacy preservation on published social networks has become more and more important. The social media data are available on the popular on-line social network websites with rich personal information, which can be analyzed for connectivity and user behaviors. In this work, we study the problem of preserving sensitive paths in social networks. We examine the new concept...
In this paper, we propose an efficient projection-based algorithm to discover high sequential utility patterns from quantitative sequence databases. An effective pruning strategy in the proposed algorithm is designed to tighten upper-bounds for subsequences in mining. By using the strategy, a large number of unpromising subsequences could be pruned to improve execution efficiency. Finally, the experimental...
In the past, the multiple fuzzy frequent pattern tree (MFFP tree) was proposed for extracting multiple fuzzy frequent itemsets from quantitative transactions. It kept the multiple transformed fuzzy regions of an item to form the multiple fuzzy frequent itemsets. In this paper, an incremental algorithm is proposed for efficiently mining multiple fuzzy frequent itemsets based on the FUP concepts and...
Intrusion detection technology has developed over more than 30 years from the host-based to network-based and has become the indispensable security technology of information systems. On the basis of the study of the existing intrusion detection systems, this paper reviews the history of intrusion detection technology, and sum up the recent hot-spot problems researched. Then, six technical difficulties...
To preserve privacy, k-anonymity on relational, set-valued, and graph data have been studied extensively in recent years. Information on social networks can be modeled as un-weighted or weighted graph data for sharing and publishing. We have previously proposed k-anonymous path privacy concept on weighted social graphs to preserve privacy of the shortest path [9]. A published social network graph...
The demand transmission process manegement is an important part of supply chain management. In comparing the current transmission process, the integrated demand transmission process has more advantages than others, but it also faces a series of risks. Because of the information-sharing platform, internal and external demand for effective integration, rigorous mechanisms in fractal reengineering demand...
With the rapid development of Web technology, more and more data on the web are considered as the source of information in current society. However, as the qualities of data fetched from different sources are different, it takes a lot of time to search the valuable data from tremendous web information. This paper proposed an approach to evaluate the data quality through integrating all dimensions...
The uncertainty of the trustworthiness of the information has been a great obstacle for users to obtain and share true information on the Internet. Therefore, it is worth to further study the evaluation of the information credibility. This paper introduces a kind of evaluation method of information credibility based on the trust features of web page. After the trust features are defined according...
The goal of higher education evaluation and accreditation is to ensure that education provided by institutions meets acceptable levels of quality. In 2011, the higher education evaluation and accreditation council of Taiwan (HEEACT) starts to evaluate the eighty-one higher education institutions through five predefined items, including (1) university goal, (2) university administration and management,...
The economic cost-benefit analysis method is used to the evaluation on roof greening projects of the urban building, the economic, environmental and social impact roof greening projects may have in the whole building life cycle is analyzed. The spatial extent and time span of the economic benefits and economic costs are determined. The path and method of economic benefit and economic cost calculation...
A novel stock trading rule is proposed in this paper. The trading rule combines self-organizing map network and K-means clustering algorithm to discover the potential features of high frequency financial data at first, and then new trading strategies are proposed to assist investors' transaction decision. The hybrid clustering based trading rule is applied to Hushen 300 Index of Chain, and compared...
The rapid development of information technology promotes the advent of ubiquitous age, and people's focus is mostly transferred to the ubiquitous learning. For the ubiquitous learning, the learning environment is important. Through studying all kinds of identification technologies, learners need the ubiquitous learning environment which they can get the right learning contents and achieve self-learning...
This paper discusses the combination of the classroom-based and the web-based learning according to the Tibetan students' characteristics and the job market to them at present, for example of the data structures' teaching. And it aims to inspire the Tibetan students' interest for learning and enhance their ability of obtaining knowledge through computer, and make them support themselves and serve...
As the rapid development of information technology and Internet technology, e-commerce quickly spreads as a new and efficient business model. Now customers can click the mouse in front of the computer to complete the complex behavior of commodity trading. E-commerce brings not only convenient, but also the issue of “information overload” and “lost resources”[1]. Customers in a large number of commodity...
A careful understanding of consumer willingness to pay(WTP) towards genetically modified(GM) foods in China will provide a scientific basis for policy decision-making on development of agricultural biotechnology, and to help companies involved in the manufacturing and marketing of GM foods in developing a profile of consumers. This study aims to estimate consumer WTP of GM foods in China and factors...
The farmers' income level is a comprehensive reflection of the national economic development level. Since the reform and opening up, farmers' income level in China has changed substantially. In this paper, we introduce some new changes of farmers' income in China in recent years. Then we establish an econometric model to analyze four main factors that influence farmers' income in China and their influencing...
