This paper considers the existence of solutions for periodic boundary value problems of fourth order impulsive differential equations. By using the method of upper and lower solutions together with the monotone iterative technique, new existence results of coupled solutions and uniqueness of problems are obtained.
Implementing modern education needs an education system, which is a group of elements relating organically together including teaching organization, teaching facilities, teaching staffs and so on, as its support. Education system is the basis for implementing education activities. In the view of the characteristics of different education activities, how to build a reasonable and high-efficient education...
In order to improve the detection efficiency of network intrusion detection system, and reduce packet loss rate and design a kind of multimedia data detection processor, the processor can analyze the characteristics of the multimedia data on network flow. It can test in advance to different types of multimedia data from the use of special inspection rules and screen out the safe multimedia to reduce...
The Innovation in Occupational Education is to serve the students and society better, which determines it should make a breakthrough in 3 aspects: serving the local economy, promoting the students' personal growth and improving their employment ability. Based on the statistical results of graduation tracking information, this article obtains the relative importance of specific measures in occupational...
With the rapid development of information, science and technology, the information network is infiltrating the various aspects of the human life, greatly influencing the social economy, culture, education, philosophy and the work, life and way of thinking of the people. this paper made analysis and study of the opportunities and challenges of ideological and political education brought by the network...
More and more clustering approaches are used in educational data mining for too many data are generated by web-based educational systems. To deal with the problem of premature convergence of the traditional K-means algorithm and computational costs, an improved K-means clustering algorithm based cooperative PSO frame is proposed in this paper. Cooperative PSO has been proved effective for large scale...
Intelligibility improvement of the enhancement algorithm proposed in our previous paper is evaluated in this paper. Joint time-frequency spectrum of the noisy whisper and clean whisper are computed based on real-valued Discrete Gabor transformation respectively. The Gaussian window is used as the kernel function which assures the best utilization of the information area for it possess the smallest...
The CDIO engineering education model is the latest achievements of the international engineering education reform in recent years, and is gradually receiving attention from our country. It advocates conceiving design implementation operation, and will promote the development of educational technology and solve some problems such as Pendulum phenomenon, indistinct training objective, less prominent...
With the rapid development in computer technology, visualization technology has plays an important role in improving teaching. However, its effectiveness is far behind the expectation. The paper discusses practical reasons that lead to difficulties in achieving desired results when Visual teaching is applied in practices. Discussions focus on sustainable development, software design, cognitive load,...
Aiming at current deficiencies of online testing system, students only know the making wrong, but also doesn't know the whys. In this paper, the online testing system is developed based on ASP.NET and AJAX technologies, which consists of 6 modules such as chapter test, comprehensive test, score query, management of test questions, etc. The online testing system is embedded into VB excellent curriculum...
Using the Tetrax test instrument, respectively, we have tested the static balance ability of aerobics group and as a special reference general group in order to explore gender and exercise training on static balance ability of young people. By detecting the indicators, that is A%, B%, C%, D%, WDI and LEFT of eight position (NO, NC, PO, PC, HR, HL, HB, HF), found that the influence of gender for aerobics...
This paper analyzes the education problems of research-oriented graduates major in computer science and proposes a cultivating mode for them from the aspects of the theoretical knowledge teaching and research capacity building to develop their innovation capacity. It gives a series of practical training methods to realize the cultivating process, so that provides the basis for the reform of computer...
Collaborating the perspectives of socialization and self regulation of learning in peer group, the research examines the practical mechanism of students' self regulation in learning at university. Individuals' self regulation in learning and the influence from the ambient of peer group were explored through the lens of regulation in different aspects of individuals' metacognition, which are monitoring...
Applying self-made questionnaires to 956 university students from five universities and colleges in Zhengzhou, Henan, China, the survey is made to gauge the characteristic features of their ideals and belief. The result shows that, to some extent, they entertain a sense of responsibility politically and socially, yet more utility in their participation motives. They take a positive and confident approach...
Providing useful information on the geometrical topology and material properties, CT data has been widely used in the finite element modeling of bone. Many researches have demonstrated the relationship of apparent density of bone tissues and Hounsfield Unit (HU) and various empirical relationships between Young's modulus and the apparent bone density have been established. Due to the partial volume...
DS (Diamond Search) is one of the most famous motion estimation algorithms. By analyzing the characteristics of DS, it is found that DS can be improved more efficiently. A Modified Diamond Search (MDS) algorithm is proposed in this paper. Firstly, MDS employs Small Diamond Search Pattern(SDSP) to judge if the MBD(Minimum Block Distortion) point is the initial search center. If the MBD point does not...
This paper studies the application of distance education carried out in scattered learning position. The role of teacher and communication are studied based on participant adult and continuing education students in a distance class. The result of study demonstrated the different effects of teacher's teaching effectiveness such as expending, rhetorical and provocative. Further, teach in distance education...
The spatial design of experiment and information subset had been studied by correlated random sequence sampling. The problems in many applied region had been found, such as statistical geology, sampling sequence, and environmental statistics. In all applications, maximum sampling sequence can be selected and different location and times. In maximum sampling sequence design, the feasible design program...
The mobile communication technology has been developed for three generations. Although the 3G Mobile Communication system can provide many wide frequence belt information services which the former two generations can't offer, it still has limitation that especially follows the structure of 2G system, which leads to the dissatisfiction of intelligence by mobile terminal. So the 4G system has been taken...
In order to discuss the insect community structure and changing regularity in Taihu wetland near Suzhou, the community characteristics of insects in four typical habitats (the wetland park, desolated beaches, phragmites australis stand and artificial forest) were thoroughly investigated. The results showed that there were 156 species of insect belonging to 11 orders, 86 families and the species -...
