With the rapid development of the computer technology and artificial intelligence, and the rapid improvement of Chinese educational information level, It becomes the hot focus in IT industry and education domain to achieve paperless examination and networking examination. The thesis, firstly, introduces the research background, the art of the state of the domestic and foreign research works. In the...
A data aggregation preprocessing algorithm for congestion control in wireless sensor networks is proposed in this paper. The algorithm decrease the repeating packet of nodes by reducing data of multiple group sensing data which belongs to a aggregation cycle with similar coefficient, thus can ease congestion of the networks. The experimental results show that this algorithm can reduce communication...
Low support makes dramatic increase in the number of itemsets and brings less efficient frequent itemset mining. Correlation measures introduced to restrict the number of frequent itemsets generated in order to improve the efficiency of mining under certain conditions. An improved FP-Tree algorithm using node linked list FP-Tree is proposed. This algorithm exploits efficient pruning strategies using...
With the development of science and technology, computer information technology has been widely applied in education and scientific research. In the process of teaching, properly using computer technology can effectively improve the teaching quality. This paper discusses some problems which Computer information technology was applied in mathematics classroom teaching and mathematics research-oriented...
For more than 20 years of development, there is a certain scale on college continuing education in China, but management model is mixed, and lack of scientific. We point out some shortcomings of common model. According to managerial experience in many years, we come up with an improved management model about large scale continuing education, describing the function of multiple roles and their relationship,...
On the multiple mixed flow reactors in series for second-order reversible reaction, the output concentration of evening reactor can be solved by algebra and wag of graph. However, the former needs a great deal of time and energy, and the later is not accurate enough. Furthermore, it can not be calculated by two methods when the number of mixed flow reactor tends to infinity. A new method which overcame...
Books classification is an important and complicated work in libraries. In order to improve the speed and accuracy of books classification, fuzzy mathematics theory is applied in books classification and a method of books classification based on fuzzy mathematics theory is proposed in this paper. Subject function is used to denote the subjection degree of books to the classes. The characteristics...
Because of the explicit, the axonometric projection is useful in engineering. But in the published books of mechanical drawing, only the characteristic and the drawing steps of the axonometric projection are focused on, and the forming method and the expression of the unapparent edges of object are not mentioned. This paper analyses the forming method by 3D graphic projective transformation in CG,...
Now the computer is developing towards the multi-core and multi-CPU, but some quintessence serial algorithm can not be well transplanted to multi-core computer, so it's necessary to make parallel analysis and improvement on the original serial algorithm. This paper analyzes matrix chain multiplication problem, and gives three algorithms based on the multi-core and multi-CPU - parting matrix chain,...
In e-government evaluation of the validity of the security system, the testing and evaluation data obtained need synthetic evaluation, which will be influenced by human subjectivity and the results of the testing and evaluation will be affected accordingly. This paper presents an integrated AHP and multi-level fuzzy synthetic evaluation method to quantitative evaluation and analysis of safety data,...
Natural language processed by computer is an important branch of language and linguistics researches, and which includes syntax, semantic and pronunciation. This paper focuses on the syntactic structure of natural language and introduces a algorithm based on Delphi which is a top-down parser to process it. At last the algorithm is proved to be correct by concrete examples.
A new method of high precision frequency measurement is proposed based on the non-AD sampling and non-analog circuit. First, the input signal is shaped by the digital system's comparison of hysteresis, then the shaped signal is measured by the equal precision frequency measurement method, through which the none synchronized phase problem is eliminated successfully. Second, the proposed method is no...
The burgeoning growth of the e-Learning technologies implies the fact that the future education system will largely depend upon the electronic devices and computer aided technologies. It has already been proved that the computer aided teaching techniques are much more effective for the children than the traditional teaching system in most of the cases. A large number of software has been designed...
Nowadays, it is already a banality that people run their applications in a complex open computing environment including all sorts of interconnected devices. In order to meet the network security challenge in nonprofessional human environments, Intrusion Detection Systems (IDS) have to be designed. Intrusion detection techniques are categorized into anomaly and misuse detection. To describe the outlined...
We have developed a hand-held test device capable of delivering visual, auditory and haptic stimuli. This device will serve as a test platform for studies of multimodal communication and integration of haptic displays into consumer electronics.
In this paper, operator based networked nonlinear control is considered for a Peltier actuated thermal process with time-varying delays. For the networked Peltier actuated thermal process, the networked property based on distributed control system is described. Then, by using robust right coprime factorization approach, the robust stability of the networked system is guaranteed. Also, a feedforward...
An infrared based test matching system hardware platform used for group psychoanalysis purpose is introduced in the paper. The platform is composed with more than 30 infrared transmit parts and one receive end, with a Microchip MCU as their processors. An innovative coding and decoding scheme is designed in this system, which shortens the IR code length and the wave circle period comparing to normal...
The test method oriented function call path acquires function call paths through static analysis, but the uncertainty between definitions and call forms of function template in static analysis produces many redundant paths, which makes test workload increase exponentially, so determining uniqueness of function template call relation is an important part of improving test efficiency. Through analyzing...
Automated reasoning has become the research hotspot among researchers, and family relations are common logic knowledge, which can be reasoned. This paper presents four basic relations on family relations, which can deduce others new complex relations. The relation knowledge was stored in knowledge database as forms of basic relations. Some common questions could be deduced successfully and receive...
This paper first explicates the concept of e-commerce business method patents and then by reviewing patents protection methods of United State, Japan and Europe explores the patentability and patent commission criteria by means of qualitative, quantitative, comparative and sample analysis. It concludes by bringing forward suggestions for establishing the protection system of e-commerce business method...
