In this paper,a new statistical distribution model exclusively used for LOS environment is proposed based on investigation of the experimental data. By reducing the number of the visible random arriving clusters,the model itself and the parameters estimating of the corresponding model are simplified in comparison with SV/IEEE 802.15.3a model. The simulation result indicates that the proposed model is more accurate in modeling small-scale LOS environment than SV/IEEE 802.15.3a model when considering cumulative distribution functions (CDFs) for the three key channel impulse response (CIR) statistics.展开更多

The rapid development of AI technology provides powerful tools to analyze massive amounts of data, facilitating physicians to make better clinical decisions or even replace human judgment in healthcare.Advanced AI technology also creates novel opportunities for exploring the scientific basis of traditional Chinese medicine(TCM) and developing the standardization and digitization of TCM pulse diagnostic methodology. In the present study, we review and discuss the potential application of AI technology in TCM pulse diagnosis. The major contents include the following aspects:(1) a brief introduction of the general concepts and knowledge of TCM pulse diagnosis or palpation,(2) landmark developments in AI technology and the applications of common AI deep learning algorithms in medical practice,(3) the current progress of AI technology in TCM pulse diagnosis,(4) challenges and perspectives of AI technology in TCM pulse diagnosis. In conclusion, the pairing of TCM with modern AI technology will bring novel insights into understanding the scientific principles underlying TCM pulse diagnosis and creating opportunities for the development of AI deep learning technology for the standardization and digitalization of TCM pulse diagnosis.展开更多

The author thinks that contemporary Chinese language and literature teaching should break the limitation of the traditional teaching mode, and we should guide the students to play the subjective consciousness and the consciousness of the emotional experience of the course learning in the cross-national literature and artistic context with various forms and rich contents, and help the students easily and autonomously integrated into the Chinese language and literature teaching.展开更多

The linear driving force (LDF) model is obtained by assuming a parabolic intraparticle concentration profile. Models Ⅰ and Ⅱ are obtained from the parabolic concentration layer approximation. Examples are presented to demonstrate the usage and accuracy of these models. It is shown that Model Ⅰ is suitable for batch adsorption calculations and Model Ⅱ provides a good approximation in fixed-bed adsorption pro-cesses while the LDF model should not be used in batch adsorption and may be considered acceptable in fixed-bed adsorption where the parameter Ti is relatively large.展开更多

It traced the origin of "half-a-day" linking it with the ingenuity of the youths to make the formal education that they have acquired operational. It also discussed the traditional education with its apprenticeship system as being modified through the "half-a-day" syndrome. The study is historical and descriptive therefore, social survey method was employed using unscheduled interview and consulting relevant literature. It was discovered that, apart from the failure of the educational system due to lack of proper infrastructure, the youths, especially those from the lower class, have reasoned that the salaries from the white-collar jobs may not be enough to sustain them. It is, therefore, recommended, among others, that: Government can institutionalise the "half-a-day" as a form of summer school and certify both the centres of learning and learners.展开更多

Experimenting a local development communication model that can be used at the grass-root level communication at the community development programs in Sri Lanka is the research objective. This study is a participatory research. Live participatory observation, impact analysis using a questionnaire and direct interview tools were used to analyze the impact of the creative model. This research study was experimented at Rasnayakapura divisional secretariat, Sri Lanka from 2004 to 2005. Results suggest that the traditional forms of communication can be utilized as a useful instrument in the rural community programs more than the dominant use of mass media and conventional use of small group communication. Forms of traditional communication are rich in communication because of their closeness to rural life, credibility, Utilization of familiar signs & symbols, Participation of the same community, collective presentation, Utilization of past experiences, plot and the stories from their own life and psychological understanding (attraction, attention, rationality). Communicating a message through entertainment was the practice of this model. Finally impact analysis confirmed the success of the model.展开更多

In the experiments, fireproof glass with a size of 3 300 mm (height)×2 200 mm (width) ×12 mm (thickness) was exposed to an oil pool fire with a power of approximately 1.4 MW. The experimental results show that the application of the water film or sprinkler system on the glass can effectively resist the intensive heat from the fire in the test due to the absorption of latent heat. The permitted period of integrity and insulation with a water film and a sprinkler system could be extended to 60 min. It should be noted that the temperature of the glass surface Can be kept under 60℃in a 60 min test. The experimental results suggest that it is feasible to substitute fireproof glass with water film for a fireproof door as long as the water film or sprinkler system can work stably and water can cover the whole surface of the frreproof glass.展开更多

Based on Chinese culture which can be characterized as lack of afterlife, the pattern of Chinese economic development has distinctive features relative to the economy of the Western world, even to that of Japan and Korea. This paper argues that culture influences economic development through two paths: One is that some cultural factors, as certain institutions, have effects on cost, especially transaction costs. Another point is that culture forms people's preferences and influences people's choices. With the influences of Chinese culture, Chinese have a weak sense for legal obedience and strong inclination for "free riding", this would increase social transaction costs. The family centered tradition of Chinese society results in Chinese features such as being good at individual struggles but poor at cooperation, the alienation between civil society and government, a strong sense for competition and a weak sense for legal obedience, seeing material wealth as important and neglecting scientific innovation. Traditional Chinese culture also has effects on the developmental pattern of Chinese enterprises展开更多

Our research starts from the basic analysis of aesthetics and traditional regression to propose the novel educational paradigm that is innovative.展开更多

Chinese renaissance can not only be understood as a catalyst for globalization, but it does also enlarge the global village by opening new economic, political, diplomatic, intellectual, and artistic horizons. Our government pays more attention to publicize and preserve traditional culture. Therefore, it becomes an urgent task about how to do research and mining, preserve fine traditional Chinese culture, and enhance the international cultural communication. Rhymed opera proverb as an important part of Chinese opera culture mirrors the ideology and culture in China. The opera proverb is responsible for both inheriting the tradition and developing the ancient art. The biggest challenge is translation which is carrier of culture. Through good translation, we will gain a better understanding of the quintessence of our tradition and of the living embodiment of China and Chinese culture. This paper is intended to study opera proverb translation from the viewpoint of "intertextuality". The author believes that translation is a type of transforming activity intertextualized with language, text, and culture. Intertextuality theory is applied to investigate the process of translation. Intertextuality will be of great help to the translation of opera proverbs, which means not only to explore and transfer the literal meaning of the source text, but also to interpret and expound the cultural meaning. Only if a translation is reliable and makes sense of traditional culture can our culture be known and appreciated by the world.展开更多
