Herein, an efficient method to prepare sulfonated polyether ether ketone (SPEEK) based cation exchange membranes (CEMs) is developed, where polyethersulfone (PES) is used as an additive. The optimized membrane of 30 wt.%PES/SPEEK‐M exhibits a rather low anion permeability and a high ionic conductivity of 9.52 mS cm−1 together with low volume swelling in water. Meanwhile, tensile strength of the membrane...
Wireless nanosensor networks (WNSNs) consist of numerous sensors with a nanoscale size and have many applications, such as the Internet of Nano-Things. The energy storage capacity of nanosensors is very limited; thus, energy efficiency has become an important issue in WNSNs. In this study, we investigate energy-efficient coding strategies and an energy consumption model for WNSNs. First, to map source...
Computer experiments play a very important role in computer major education. How to make the students master various computer skills better by the experiments is always a big challenge for the teachers. Here the method of micro-test is put forward to improve the experimental effect. Combined with some major factors like the course's features, the students' knowledge structure, their psychology, the...
In order to broaden the students' operative ability and employability, a variety of competitions are held in software industry. Jiangxi Normal University's School of Software participated in a lot of software contests and obtained a certain achievement. With the aim of combining the software events with teaching activity, while the requirements of teaching scheme are completed, we improve the students'...
Under the guidance of analytic hierarchy process and genetic algorithms, establish three evaluation index systems for courses, by means of analytic hierarchy process, which improves accelerating genetic algorithm by real-coding, to weigh the evaluation index systems, and you can well evaluate the rationality of courses set up by colleges.
With the increasingly competition in E-commerce, the analysis of the loss and value of consumers has become a key problem to the enterprise organization. A strong attributes restricted Bayesian classifier is described in the paper, the SANBC which is a restricted Bayesian classifier based on strong attributes extends the structure of the naïve Bayesian classifier through the adding of highlighting...
With the increasing application based on Web, the comparatively backward Web printing technology lead so much inconvenience to the development of Web system and slowed the pace of Web application in enterprises. In this work, by making use of component programming ideas and EJB technology, a Web print components was developed which based on the analysis of PDF format. Thus, it provides a simple and...
Software project management is a sub-discipline of project management in which software projects are planned, monitored and controlled. The software project management course has become the core curriculum of many software Institutes. However, because it is one of the management courses, it has strong practicality. But students lack the background of project practice, which leads to a bad teaching...
A kind of attribute reduction algorithm of Jiahua Lu was firstly introduced and its performance was analyzed briefly, then aimed to its improvable points, a new attribute reduction algorithm based on the binary discernibility matrix and an improved attribute importance function that utilized the potential information of the information system, which considered attributespsila occurrence number and...
Recommendation systems are widely used to cope with the problem of information overload and, consequently, many recommendation methods have been developed for the present recommendation systems, such as content-based, collaborative filtering, Web mining-based and so on. But they are always lack of intelligence, self-adaptiveness and initiative. Aiming at these disadvantages, in this work, a personalized...
Interactivity is the focus of the study in multi-agent system, and agent communication language (ACL) is the base of interactivity and cooperation. Under the current environment of agent, the current mainstream communication language KQML and the shortcomings of the associate content language are analyzed. With the mainstream technology XML in WWW, the integration method between the XML language and...
One of the keys to constructing decision tree model is to choose standard for testing attribute, for the criteria of selecting test attributes influences the classification accuracy of the tree. There exists diversity choosing standards for testing attribute based on entropy, Bayesian, and so on. In this paper, the degree of dependency of decision attribute on condition attribute, based on rough set...
