A Cognitive Study of Preposition Ellipsis in Radiotelephony Communication  [PDF]
Wei Chen
Open Journal of Modern Linguistics (OJML) , 2016, DOI: 10.4236/ojml.2016.65035
Abstract: The research on the omission in the field of linguistics can be divided into the perspective of transformational generative grammar and functional grammar. The research on the omission from the perspective of transformational generative grammar is mainly embodied in the present study of the empty category, and the function of omission is regarded as an important means to make textual coherence. This paper attempts to apply the findings in cognitive linguistics to study ellipsis in radiotelephony communication in English, with the theory of cognitive linguistics to explain in detail the ellipsis of radiotelephony communication and ellipsis, to the maximum extent to avoid ambiguity or misunderstanding appear radiotelephony communication among different users.
An Empirical Analysis of Port-City Relationship: Based on the Comparison of the Yangtze River Delta and the Pearl River Delta  [PDF]
Wei Chen
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.55016
Abstract: This paper first analyzes the status quo of the port-city relationship of the Yangtze River Delta and the Pearl River Delta through the relative concentration index. It is found that the port-city relationship of the Yangtze River Delta trends to be coordinated, while the port-city relationship of the Pearl River Delta is still in a state of uncoordinated. Then it analyzes the specific correlation between urban economy development and port development by gray relational analysis; it is found that the GDP and industrial output have high correlation with port cargo throughput, and the average correlation value of Yangtze River Delta is higher than that of the Pearl River Delta. Through the impulse response analysis, it is found that the urban GDP and industry have a significant effect on the development of the port in the short term, and the development of the port has no obvious influence on urban GDP and industry.
The Two-Dimensional Simulation Study of Flow Pattern near Guiding Wall of Oxidation Ditch  [PDF]
Wei Chen, Mingming Xu
Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.29096
Abstract: Guiding wall is used to change the flow of the oxidation ditch as supporting structure, it widely uses eccentric setting, and its setting parameters are mostly empirical judgments. According to fluent software that simulates the velocity distribution of the guiding wall, to discuss the settings of the guiding wall in different length of downstream extension, eccentricity and guiding wall radius, so to work out its optimized settings.
Simulation of a Triple Inverted Pendulum Based on Fuzzy Control  [PDF]
Wei Chen, Nkurunziza Theodomile
World Journal of Engineering and Technology (WJET) , 2016, DOI: 10.4236/wjet.2016.42026
Abstract: The inverted pendulum is a classic problem in dynamics and control theory and is widely used as a benchmark for testing control algorithms. This paper studies the use of fuzzy control method to study the stability control problem of a triple inverted pendulum system. By the linear model of the system, the feedback weight matrix of the LQR optimal control and the feedback parameters of the linear optimal control are designed to determine the parameters of the fuzzy controller. The simulation results show that the proposed method can achieve the stability control of the three stage inverted pendulum, and has good dynamic performance with simple parameter selection.
A Discussion on the Construction of China’s Public Finance System
Wei Chen
International Journal of Business and Management , 2009,
Abstract: With the development of China’s market-oriented reform, a public finance system going with the socialist market economy should be established. Based on the analysis on the main features and basic principles of the public finance system, this article put forwards some detailed measures to construct such a system in China.
Business Risks, Business Strategies, HRM and De-Globalization
Wei Chen
Asian Social Science , 2009, DOI: 10.5539/ass.v5n1p18
Abstract: Globalization is regarded as an overwhelming tendency which can bring about great benefits and freedom to nowadays market. However, de-globalization was addressed by many writers since the world is full of uncertainty and unpredictable changes. HR, as a strategic tool for multinational firms, should play an active role in the preparation for the possible coming de-globalization. HR should be active to improve its strategy, policies, and practices to guarantee the competency of company in this changeable environment.
The CollegeTeachers Role in Promoting on the Construction of Style of Study
Wei Chen
Education Research Frontier , 2011,
Abstract: The style of study is an important component of a university spirit connotation, which can promote the quality of talent cultivation actively. The construction of style of study needs the simultaneous construction of teachers team, management team and the students themselves. The paper analyzed the current status and causes of construction of study style in universities, and according to the department of mechanical and electrical engineering of Heze University, it put forward that the building of college teachers is a breakthrough of the construction of style of study. Therefore, we should give full play to the important role of each teacher in the construction of style of study.
Thermodynamics of an Anyon System
Wei Chen
Physics , 1995, DOI: 10.1103/PhysRevD.52.6122
Abstract: We examine the thermal behavior of a relativistic anyon system, dynamically realized by coupling a charged massive spin-1 field to a Chern-Simons gauge field. We calculate the free energy (to the next leading order), from which all thermodynamic quantities can be determined. As examples, the dependence of particle density on the anyon statistics and the anyon anti-anyon interference in the ideal gas are exhibited. We also calculate two and three-point correlation functions, and uncover certain physical features of the system in thermal equilibrium.
Renormalization Group Flow of Four-fermi with Chern-Simons Interaction
Wei Chen
Physics , 1994, DOI: 10.1016/0550-3213(94)00376-P
Abstract: We introduce Chern-Simons interaction into the three dimensional four-fermi theory, ad suggest a possible line of non-Gaussian infrared stable fixed points of the four-fermi operator, this line is characterized by the Chern-Simons coupling.
Phase Transition in (2+1)d Quantum Gravity
Wei Chen
Physics , 1994,
Abstract: (2+1) dimensional gravity is equivalent to an exactly soluble non-Abelian Chern-Simons gauge field theory (E Witten 1988). Regarding this as the topological phase of quantum gravity in (2+1)d, we suggest a topological symmetry breaking by introducing a mass term for the gauge fields, which carries a space-time metric and local dynamical degrees of freedom. We consider the finite temperature behavior of the symmetry broken phase, and claim a restoration of the topological invariance at some critical temperature. The phase transition is shown of the zeroth order.
