International students studying in China need cross-cultural communication. This paper takes international students of foundation in one university and CLS students of United States as targets, collects a large number of primary cases of international students' cultural adaptation, and conducts an analysis and study to clarify the importance of nonverbal communication for intercultural communication and cultural adaptation of foreign students. Three major ways to improve nonverbal communication skills are proposed: teacher guidance, language partner guidance and independent study of international students.
Power quality issues are now considered to be essential features of successful power system due to the load, which results in a rapid increase in noise. Voltage sag is one of the hottest topics in dynamic power issues. In this paper, the short duration power quality disturbance detection method based on S-transform is chosen. The complex matrix and the amplitude matrix of the results of the S transform are used to extract waveforms to analyze the amplitude, phase jump, duration and harmonic of the disturbances of voltage sag under various circumstances. Simulation results show that the proposed detection method could detect the characteristics of voltage sag quickly and correctly.
The purpose of this study was to understand the sociocultural adaptation status for international doctoral students of the “Confucius China Studies Program” (CCSP), as well as obtain suggestions from those students to the management of the program. This qualitative study applied an instrumental case study at a research site university in Beijing. Through distributing questionnaires to international students who participated in the program, as well as conducting one-to-one interviews with seven international students and two program management teachers, this study found that the sociocultural adaptation status of the international students of CCSP was generally high. The sociocultural adaptation status for doctoral students of the CCSP was analyzed from five aspects including interpersonal communication, academic performance, personal interest and social participation, environmental adaptation, and language proficiency. The interviewed international students proposed three suggestions to the management of the CCSP, including holding exchange and sharing activities for international doctoral students of the CCSP, compiling CCSP manual for international students of the program, and the establishment of a student writing center. This study also provides implications to administrators of the CCSP, international doctoral students, and policy-makers of this issue.
In order to identify the power oscillation of the power grid and take the corresponding measures quickly,a method of identification for power oscillation based on the measured signal curve in power system is proposed.The measured data is processed to extract the overall trend of the signal and combining with the technology of envelope detection and the soft threshold,the intelligent analysis of the power curve and the fast identification of the power oscillation is realized by the adaptive algorithm.The method can judge the beginning time of the disturbance within several cycles as well as overcome the shortcomings of the traditional method of hard threshold,which is not accurate enough.Finally,the effectiveness of the proposed method is verified by an example of power oscillation in the power grid.
Recent years, more and more company have focused on their human resources management, and separation becomes a very important factor. This thesis analyzes the influence of separation rate on company, so as to manage company better. First, we apply Analytic Network Process to construct a dynamic model, studying the factors which affect the separation rate. Second, thesis explains the way of separation infection and assess direct and indirect effect of separation on productivity. Last, we use Matlab to simulate the situation when company cannot control separation, it will appear the "separation explosion", then manager can early avoid to fluctuations in employees system. Through simulation, company will develop healthier and healthier in long-term. In results, employee's level and department have a tightly relationship with separation, and this stir can o diffuse from employee to employee. This report supplies method to identify those people that are likely to leave to prevent further churning. The multi-layer complex networks we get are convenient to evaluate the operational status at multi-angle. Company can use it to improve the management. On this condition, the company will develop healthier in long-term.
This article analyzed the concept of ecodesign and its various manifesting modes from the perspective of the traditional folk packaging’s materials and forms. The discovery and recognition of the value in traditional materials can be used for reference by modern packaging design to achieve the goal of ecologicalization and sustainable development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
