Synchronization is an important problem in the design and development of the software, which has been resolved in the object-oriented programming (OOP). However, the implementation of OOP is easy to leads to code-tangling and code-scattering between functional properties and crosscutting properties. Aspect-oriented programming (AOP) can solve the problem of code-tangling and code-scattering, and provide...
At present, storing XML document in a relational database is a hot topic because relational databases are mature and scale well. In this paper, a novel relational database storage structure that can store XML document is proposed. An algorithm that translates XML document to relational database is given according to the proposed storing structure and algorithms that translate XPath Query to SQL Query...
Canonical Correlation Analysis (CCA) is a well-known method for feature extraction and dimension reduction. CCA can simultaneously deal with two sets of data. It makes CCA can be used for feature level fusion. But it suffers the Small Sample Size (SSS) problem. In this paper, a new optimization criterion is presented for overcoming the SSS problem. The optimization problem can be solved analytically...
There are three parts of Digital Educational Resource Platform - Educational Resource, Support system and Learning Environment. The design strategy of Digital Educational Resource Platforms in University is making cleanly what the users need, integrating standardize, efficient architectures, open Stand-point. The procedure of designing the Digital Educational Resource Platforms is analyzing and designing...
With the continuous deepening of the reform of higher education and deepening the continuous development of the educational system, the Chinese University teaching management is also faced with new challenges. The merger of a number of colleges and universities, schools, the multi-facet management and all sectors database used by the data structure are different. In light of this situation, completely...
After the analysis of the existing network teaching system limitations, this paper indicated that the existing network education system could not adapt to the changes in management mode of teaching and could not share the information and resources in a wide range. Inspired by the advantages of service oriented architecture (SOA), SOA-based network teaching system was proposed. In the mean time, a...
The issue of page??s form submission has been a troubled big problem for the software developers, and this paper through the analysis of the form submitted by several commonly used methods solves that: using the technology of Ajax for submitting form to prevent repeat submission is a good choice. The technology of Ajax achieves not only implementation the need of the problem, but also greatly improving...
Business process modeling is the key operation of Web services composition, and it is a new method for business process modeling by using communicating sequential process (CSP), current research only focuses on the functional requirements of Web services composition, but it ignores the non-functional requirements, although Timed CSP (TCSP) can analyze timing attributes of Web services composition,...
The Chord protocol is the best known example of implementation of logarithmic complexity routing for structured peer-to-peer networks. Its routing algorithm, however, does not provide an optimal trade-off between the size of the finger table and the average number of hops to reach destination. Lately, a base-k chord appeared based on the original Chord, the routing perfomence of this system improved...
The graduation practice and design is a comprehensive education process in cultivating talents in the university. It becomes more difficult due to the increasing graduates and the employment pressure. According to the analysis of some critical problems, such as the similar subject and incompact management etc., especially the investigation in graduation design in recent years, the paper prompts a...
On the foundation of the domestic and international research work, we have used recurrence plot and cross recurrence plot to study the different behavioral form of time series with different characters on its responding recurrence plot and cross recurrence plot. When the time series engender the phenomenon of Lorenz system, stable sink, saddle, bifurcation point and Hopf bifurcation the recurrence...
Grouping aggregate queries Based on Sliding Window is a focus problem in data stream research. Among existing research works, the grouping aggregate algorithms are presented for immediate continuous queries, and they didn??t take into consideration the effect of data structure in the sliding window on the performance of the algorithms, the data structure in the sliding window is all chained list....
This paper deals with a mathematical model of tumor invasion developed by Chaplain and Lolas. Besides random motion, the tumor cells are directed not only by haptotaxis (cellular locomotion directed in response to a concentration gradient of adhesive molecules along extracellular matrix) but also by chemotaxis (cellular locomotion directed in response to a concentration gradient of the diffusible...
Owning to the expansion of network scale and complication of network construction, it has a big challenge to previous network monitoring technology. After analyzing the network monitoring technology and IA (intelligent agent) technology, in this paper, a method based on IA is proposed to complete dynamic network monitoring, developed by a cross-platform language Python, including two monitoring modes:...
With the general use of Information Management System, log management is more and more important. After analyzing the requirements of log service on large-scale information management system, the idea of specialization, high reliability, easy to operate and manage comes out to sort the problem of limitation on current log management kit. The paper??s main idea is to achieve specialization, practical...
