The main characteristics and the classifications of P2P systems are discussed. Considering the requirements of P2P application modeling and referring to the component-based modeling thought, a description method based on communicating sequential processes (CSP)is proposed for the P2P network models. By using a CSP process group, this method can describe the dynamic interactive relationship which focuses on multiparty concurrent interaction of P2P systems more advantageously and accurately. The application of nondeterministic semantemes of CSP in describing the interactive relationship of P2P networks is discussed. The advantages and description abilities of the proposed method are demonstrated through the modeling of a new P2P media-on-demand system.展开更多

Facing highly developed information technology, and the rapid development of the network, strengthen ideological and political education is very important, the network has put impressive and comprehensive impact on the university teachers and students' lives, learning, work, moral, ideological and political attitudes, moral outlook, political literacy, life values, and ideological and political education in universities is facing a new challenge ; Meanwhile, the network also provides many new challenges and opportunities, expanding the channel and space of ideological and political education, it also can improve the quality of the main ideological and political education of high demand. Therefore, the educators of ideological and political education in colleges should keep up the pace of the rapid development of large- era, became not only who has a good ideological and political quality and comprehensive cultural knowledge quality, but also has very high literal ability and a solid information of network technology skills, so they could give full play to the advantages of information networks, do research and create a new situation in a large network of ideological and political education, then make the traditional ideological and political education produce a qualitative leap.展开更多

If humidity is too high or the change is too fast it will lead to an abnormal change on data. The intelligent real-time humidity analysis and monitoring system of a geomagnetic room and probe can not only monitor and display the change of humidity in the geomagnetic room and send an alarm signal when it exceeds the pre-set range, but also dehumidify intelligently. One can arbitrarily control the sensor to monitor the ambient humidity of the probe in order to ensure that the data is stable and true. The design idea and main functions of the system are introduced in the paper.展开更多

Music education is presented in the relationship of the two main areas: science and education. There is evidence of a gradual expansion and changes in the content and methods of the science of music. The 21st century rapidly and dynamically entered in our lives in terms of the development of information communication, technological progress and unprecedented rise of scientific thought. Social upheavals of this period of history, a powerful wave of liberation movements have caused an unprecedented intensification of national creative forces committed to the development, expansion of contacts, attached to the other cultures. To date, the science of music has evolved so much on what grew out of it and separated into clearly separate spheres with their problems, trends, directions: music theory, music history, ethnomusicology, musical philosophy, and also music source studying. And it should be noted that each of these areas has its embodiment in materialized form of faculties, departments in the conservatory. Development of new standards, new plans, programs, new courses is a related process of development of these sciences in general.展开更多
