Guoping Cheng,Chengqiang Liu 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.5

Nowadays, because of air pollution, the lack of energy and the rising demand of motor vehicles, china’s government has published much policy to encourage the development of the new energy car industry. However, it doesn’t work as expected for the lack of effective business model of the market promotion of the new energy car industry. The development of urban public environmental protection and logistics industry call a stable demand of urban logistics cars; and the environment pollution and traffic problem provide a wide space for the market of battery electric vehicles used as urban logistics cars. This paper analyzes current circumstances and problems of the market of new energy cars, provides a business operating model of battery electric vehicles, which is setting up an individual operating company, and states different operating models with different subject of operation. Based on all these conclusions, the paper discusses the implementation condition, process, economic benefit and relative policy advice of business promotion model of the individual operating company with a topic of battery electric vehicles used as urban logistics cars, in order to commercialize them from the demand of the market.

Guoping Jiang,Weijun Tao 국제구조공학회 2014 Structural Engineering and Mechanics, An Int'l Jou Vol.51 No.4

A chaotic vibration isolation system is designed according to the chaotic vibration theory in thispaper. The strong nonlinearity is generated by the system. Line spectra in the radiated noise maybe easily detected caused by marine vessels. It is Important to reduce the line spectra by improving the acoustic stealth of marine vessels. A multi-degree-freedom (MDF) nonlinear vibration isolation system (NVIS) system is setup by the experiment and finite element method. The model is established with finite element method. The results show that the behavior of the device gradually varies from period bifurcation into chaotic state and the line spectrum is changed from single spectral structure into broadband spectral structure.It is concluded that chaotic vibration isolation is preferable contrasted on line spectra isolation.

A Random Deflected Subgradient Algorithm for Energy-Efficient Real-time Multicast in Wireless Networks

( Guoping Tan ),( Jianjun Liu ),( Yueheng Li ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.10

In this work, we consider the optimization problem of minimizing energy consumption for real-time multicast over wireless multi-hop networks. Previously, a distributed primal-dual subgradient algorithm was used for finding a solution to the optimization problem. However, the traditional subgradient algorithms have drawbacks in terms of i) sensitivity to iteration parameters; ii) need for saving previous iteration results for computing the optimization results at the current iteration. To overcome these drawbacks, using a joint network coding and scheduling optimization framework, we propose a novel distributed primal-dual Random Deflected Subgradient (RDS) algorithm for solving the optimization problem. Furthermore, we derive the corresponding recursive formulas for the proposed RDS algorithm, which are useful for practical applications. In comparison with the traditional subgradient algorithms, the illustrated performance results show that the proposed RDS algorithm can achieve an improved optimal solution. Moreover, the proposed algorithm is stable and robust against the choice of parameter values used in the algorithm.

A Novel Flexible PCB Conductive Structure for Electrodynamic Bearings and Measurement in its Induced Voltage

Guoping Ding,Jan Sandtner,Hannes Bleuler 대한전기학회 2015 Journal of Electrical Engineering & Technology Vol.10 No.5

This paper proposes the concept of FlexPCB(flexible Printed Circuit Board) conductive structure for electrodynamic bearings. It has three main advantages: easy “printing” of considerably thin conductive wires, resulting in potential reduction in stray eddy currents; realization of specific conductive configurations with high precision to optimize the eddy current flowing; simplicity in being wound to cylinders or hollow cylinders of different diameters. To verify this new concept, the FlexPCB conductive structure was manufactured, an axial electrodynamic bearing test rig was built and the conductive structure’s induced voltage was measured along the axial displacements from 0mm to 56mm at three rotating speeds. The finite element method was used to calcuatlate the flux density of electrodynamic bearing and induced voltage of the FlexPCB conductive structure. The experimental results are compared with the results from the FEM calculation. It is concluded that the measured and calculated induced voltages have consistency in the middle part of the bearing.

Higher order electro-magneto-elastic free vibration analysis of piezomagnetic nano panel

Wang Guoping,Hao Huadong,Arefi Mohammad 한국CDE학회 2021 Journal of computational design and engineering Vol.8 No.3

This paper investigates electro-magneto-elastic free vibration responses of piezomagnetic cylindrical nano panel subjected to electro-magneto-mechanical loads based on third-order theory. Third-order shell theory is used for description of the displacement field. The zero transverse shear strains are obtained using the third-order displacement field. Hamilton’s principle is employed to obtain the governing equations of motion. The nano panel is subjected to a coupling of magnetic and electric loads, including a linear function along with the thickness direction and a 2D function along with the axial and circumferential directions. To account the effect of nanoscale in governing equations, the Eringen nonlocal elasticity theory is used. The numerical results are obtained to investigate the impact of significant parameters such as axial and circumferential mode numbers, the nanoscale parameter, applied electromagnetic potentials, and length-to-radius ratio. It is concluded that an increase in initial electric potential and a decrease in magnetic potential lead to an increase in natural frequencies of the nano panel.

許國萍(Xu Guoping),宋眞喜(Song, Jin-hee) 중국어문학연구회 2014 중국어문학논집 Vol.0 No.84

According to previous researches, Chinese four-word idioms are difficult to teach and learn. Chinese as second language learners usually avoid using idioms or make various errors. This article examines the issue of how to use contexts and scenarios to teach and practice idioms in an idiom course, then investigates the products written by the learners, which are based on scenarios composed by the teacher. The results show that all the learners acquire high frequencies and correctness in their writing assignments.

“一律”“一概”的對比硏究和認知解釋

許國萍(Xu Guoping),宋眞喜(Song, Jin-hee) 중국어문학연구회 2013 중국어문학논집 Vol.0 No.78

This paper firstly discusses the different syntactic and semantic features of the two adverbs ‘yil?’(一律) and ‘yigai’(一?) in Mandarin Chinese, then examines their frequencies and ratios of positive and negative sentences containing ‘yil?’ and ‘yigai’ in different discourse types. The two adverbs show obvious distinctions on these aspects. The paper finally proposes that all those differences come from different schemas of ‘yil?’ and ‘yigai’.
