E-learning implemented in distance education has been developing rapidly in China since 1999. Along with the rapid development, China modern distance education encountered many difficulties. How to provide personalized learning support for massive distance learners is one of the difficulties. Researchers have suggested that learning style as habitual ways of perceiving and processing information has...
Smart devices, i.e., smartphone, have come into our daily lives, which become obviously inseparable. Although a variety of functions (e.g., gaming, networking, etc.) are provided, making calls remain the major task. This phenomenon implies the possibility of understanding human behaviors, especially the action contexts (e.g., moving preference, regularity, sociability, etc.), can be expected. In addition,...
The spectrum of Time-Phase Modulation will spread because of its discontinuity in phase, and the bandwidth couldn't be assured so that common filters fail to filter meanwhile preserving available messages. This paper considers adopting notch filter which can transfer phase information into magnitude information, and the notch affect will promote the amplitude of discontinuity in phase to display within...
Snapshot was not realized as a basic function in distributed database HBase. This paper studied on the key issues and the progress of design and realization of snapshot of distributed database HBase, realized the function that recover the HBase table to the snapshot created state through the snapshot recovery, and verified its availability by experiments.
Occupational differentiation of farmers has important significance for promoting the development of agricultural modernization and the modernization of the State. Occupational differentiation of individual farmers in China is different in degree, and farmers ' occupational differentiation in this article is divided into three types -- the professional farmers (undifferentiated ones), part-time farmers...
Serious ice covering on transmission line will make the line overload. As a result, it may cause many problems to equipments of the power system, such as power towers falling down, lines broken, icing flashover, network disconnecting and so on. With the development of power grid, there are more and more ring networks in the grid. Considering the unique structure of this network, this paper proposes...
In the work, an example-based method of touching string segmentation is proposed. Using Markov random field, the candidate patches based on the compatibility of the neighbour patches are selected. The outputs of the MRF after the iterative belief propagation form a segmentation probability map. The cut position is extracted from the map. Experiment results are presented and demonstrate the effectiveness...
Vertical Organic Thin-Film Transistors (VOTFT) that consisted of copper phthalocyanine(CuPc) which sandwich structure of Au(Source)/CuPc/Al(Gate)/CuPc/Au(Darin) have been fabricated using vacuum evaporated technology. When the conditions of bias voltage was VDS=2V, IDS/IGS=1000 and current density JDS=1.1mA/mm2
The awareness of architecture students on building energy efficiency technologies plays a key role on the building energy conservation. A survey has been carried out to investigate the awareness of building energy efficiency technologies in architecture students in Zhejiang University of Technology. The survey results indicate that architecture students have insufficient knowledge of building energy...
This paper describes a novel method based on self-adaptive subdivision mesh for geometry correction of multi-cameras in a panoramic video system. The system hardware consists of an array of six board cameras pointing outwardly. Digitally combining synchronized frames from each camera, a wide-field panoramic video can be created. Using sparse initial corresponding points between the ideal target surface...
Data mining is the analysis of (often large) observational data sets to find unsuspected relationships and to summarize the data in novel ways that are both understandable and useful to the data owner. Association rules are highly popular data mining method. Association rules show attributes value conditions that occur frequently together in a given dataset. And apriori is an efficient association...
Some problems of file uploading always come across at developing of Web site. In this paper we introduced a way of uploading file which edited with VB.NET in the experimental systems. We emphasized to discuss the theory of uploading file which edited by VB.NET, to achieve the key factor of file uploading based on Web mode , principally to comprehend devising project and assaying theory and editing...
