However, despite its pervasiveness, digitalization in various purposes and application in many human-based activities, it still plays the role of assisting and supporting people in manipulating and acquiring information. This study developed a ubiquitous learning environment based on the connection between digital and physical information. By using mobile learning technologies, including interactive video-based multimedia technology, GPS, GIS, and the electronic map service, learners can perform location-aware learning activities and experience corresponding appearances regarding a particular location. Accordingly learners can acquire new knowledge by participating in location-aware learning activities. We also demonstrate a ubiquitous learning activity of introducing the history of Tamkang University, Taiwan, and assess the effectiveness of the proposed ubiquitous learning environment.","PeriodicalId":360193,"journal":{"name":"J.

Matched filter is a simple and effective action potential detector, but it is found to be too sensitive to the amplitudes differences among the action potentials to be useful in general applications. By introducing adjust function, an improved matched filter detector is proposed. The detector eliminates the variance of differences among action potential amplitudes produced by matched filter. The method is tested and the results show that the improved matched filter outperforms classic matched filter method and energy operator method by getting higher correct ratio and lower false ratio.","PeriodicalId":360193,"journal":{"name":"J.

In order to address these issues, this paper presents a comprehensive learning velocity boundary condition (CLBC), which is verified by Rastrigrin and Rosenbrock function with 30 dimensionalities in three types of search range. The CLBC shows comparatively faster convergence ability and obtains more precise results, compared with other boundary conditions of the same kind.","PeriodicalId":360193,"journal":{"name":"J.

All countries have regarded strengthening the independent innovation capability as the strategic basis for national sustainable development, and are committed to their own national innovation system (NIS) planning and construction. NIS is a complex open system composed of different innovation subjects, which undertake the important task of national innovation and development. In the information environment, the NIS can’t work without a strong guarantee of information resources, and the scientific, rational, optimal allocation of these information resources. As the first country to put forward the NIS, Finland has achieved distinctly in knowledge innovation, information resources allocation and so on, thus it is a typical example for information resources allocation of other countries. This article starts from the research on the basic structure of Finland’s NIS, then analyze the information flow mechanism of the system. According to the present innovation situation of Finland, this article focuses on three types of information resources allocation mechanism used by Finland government currently. They are multi-input mechanism, dynamic distribution mechanism and integrated configuration mechanism. The present situation of information resources allocation of Chinese NIS has been compared with that of Finland, and then some concrete problems in China information resources allocation are pointed out. With reference to Finland’s success, this article suggests that China government should improve the information resources allocation of NIS from the following four aspects: management model, implement process, structure of resource input and the construction of service platform.","PeriodicalId":360193,"journal":{"name":"J.
