With the rapid development of the network technology and education technology, network education is developing quickly. The development of network education promotes the research and development of a variety of software and systems supporting network education. But most of the existing network education supporting systems lack of personalized learning environment and are less intelligent, which can...
In the mobile agent system, the authentication and identity delegation of mobile agents are the important security problem. This paper focuses on the issues faced by a relying party when deciding to trust a CA and the certificates that it issues. The scope of this paper is limited to examining the basis for trusting a relying party places in an identity certificate signed by a CA. Some of the working...
Higher education tuition must take account of the quality of cultivation and the economic endurance of ordinary family. This requires a reasonable standard of higher education tuition to ensure the healthy and continual development of higher education. This paper focuses on four factors such as the social benefit from higher education, the cultivation quality of universities, the economic endurance...
This research started with the design and implementation of an online digital video database, followed by a study of how three student teachers used it in building a virtual learning community that enabled the sharing of teaching practices during their first teaching practicum in the teacher education program. The student teachers made use of teaching practice videos that were edited into “learning...
The condition-based maintenance (CBM) technique has been widely used in the power plant in China. Feed water pump is one of the most important general requirements in the power plant. Its reliability plays an important part in the safety of the complete running. On the basis of practical situation in one power plant, a system for condition-based maintenance of the feed water pump in said power plant...
Security is to grant access to a legal user, and to prevent the system from illegal or non authorized person. The so called process of Authentication has five factors in modern era. Something You have (e.g., a hardware token/credit card), Something You are (e.g., a fingerprint, eye print), Something You know (e.g., a password/PIN code), Somebody You know and Something You Process. In this paper, we...
Information quality is one of the important indices in measuring quality of an individual in the era of information economy. This paper starts with an questionnaire survey conducted against campus college students, discusses the influence on students' information quality exerted by students' source conditions such as gender and region, then puts forward some countermeasures based on these statistical...
Education quality directly influences the effectiveness of teaching and has been widely subjected to public attention; however, the content of education quality and the interaction among the various factors are still not known. In order to effectively control education quality, the educational administration hopes to continue to improve education quality through regular evaluation; however, quality...
This paper argued that information technology (IT) can improve innovation performance in higher education institutions (HEIs) and provided evidence of a linkage between IT investments and innovation performance in HEIs. Based on extensive empirical research, using comparative and dynamic analysis, the paper presented the integrated architecture of IT and educational innovation and explained what its...
In order to explore a teaching and learning model based on a combination of student-centered teaching concept with web-based teaching technology, a goal-oriented teaching model was put forward. Comparing and analyzing the study results in three examinations of the learners, the learners performance in one-year web-based English listening autonomous learning model was studied. The learners were from...
This article introduces a Computer Aided Instruction platform based on Augmented Reality. The platform can superimpose virtual objects and virtual characters on the classroom. Teachers can interact with the virtual objects and virtual characters by presenting and moving special vision markers. In the platform, machine vision technology is used to implement human-computer seamless interaction, Virtual...
In the structure theory of many-valued logic function, the decision for Sheffer functions is an very important problem, which is interrelated to the decision for completeness of functions set, and the solution can be reduced to determining the minimal coverings of precomplete categories. It's well known that each precomplete set is a function set, T(Gm), preserving the relation Gm, therefore, the...
Because of the unique characteristics of Single-Chip Microcomputer, some students find it is very hard to learn it well at the first sight. Especially the materials and books used nowadays are often focusing too much on the structure, system and function of the Micro-Controller Unit (MCU for short). However, there exists an extremely shortage on the experiment content and technique. Some suggestions...
Constructivism as a guide, combined with the characteristics of physical education and practical needs, design “Independence, interaction and innovation” sports network teaching platform which breaking the traditional concepts and methods of teaching, providing students with independent study and learning environment platform. play a positive role in enriching teaching resources, promoting teaching...
A new method of B-Rep model partial matching based on topoisomerase is proposed. By extracting B-Rep information of the model, the CAD models are represented by the AAG (attribute adjacent graph). Next, the CAD models are expressed as the same topology by Euler operation. Finally, the sub-graph isomorphism approach is used to achieve the partial matching. Experimental results show that this method...
This paper introduces the basic conception of Mobile Learning and also analyses the learning theory enlightenment for the design and development, it also introduces system structural design and function module design, and realizes the function of each module. This Mobile Learning system is realized some functions, for example mobile study, Network Teaching, and teaching evaluation, the major function...
This paper described the roles of computer network technology in physical subsidiary education teaching, and then combined with the specific application, to make a detailed analysis of the user needs, and proposed the development program of supporting system and its implementation by the network of physical education. The system uses three-layer system architectures, focusing on the good extendibility,...
