        은희경의 「내가 살았던 집」에 나타나는 영화적 기법

        김예니(Kim Ye-Nie) 돈암어문학회 2005 돈암어문학 Vol.- No.18

        The strategy of the narrative in the novel of Eun Hi-Kyoung is verified. First, in her text whose character has “the cynical smile” and “the feigned wickedness”, which has the peculiarity that a “focalizer” and “voice” in the text is divided and overlaped. When a focalizer and voice is certainly divided, a focalizer secures the distance with the objectivity and just get a view of the world and the object as well as a character in the text with a view of “the cynical smile” and “the feigned wickedness”. But in the story about the past which is located in the interval of the present time, a focalizer and voice is unjustly divided, or overlaped almost. And throughout this story about the past, A event of the precent which looks meaningless acquires the meaning. At this time, we can realize that the writer is hiding away a restrained desire and thought behind the “the cynical smile”.<br/> Second, the Hard-cut of Montage which appears in the 「The House that I had been」 shows the transformed space made in the memory which looks the object. The arrangement that the past and the present, or difficult stories, or the object and the space stand in a line gives a reader the construable space. At the same time, the meaningless event that happens now has the meaning throughout the memory about the past and a reader can see and feel the space closer than others. Those peculiarities are the modern novel's and film-art's. Eun Hi-Kyoung makes the effect throughout the strategy of the narrative which evokes “the cynical smile” and "the feigned wickedness" that it is made in that a focalizer and voice is divided and overlaped, or situations and shots stand in a line.

        A Damage Constitutive Model of Q345B Steel in Circular Tubes Based on Cyclic Experiments and Its Application on Structure

        Gui-bo Nie,Chenxiao Zhang,Xudong Zhi,Kun Liu,Huihuan Ma 한국강구조학회 2019 International Journal of Steel Structures Vol.19 No.2

        Q235B and Q345B are two structural steel grades widely used in China. In previous studies, more precisely in 2012, Nie defi ned a normalized constitutive model using material damage accumulation to describe damage behavior of Q235B steel in circular tubes. This paper focuses on the hysteretic damage behavior of Q345B steel in a circular steel tube under cyclic loads and describes the damage mechanism through a damage constitutive model based on experimental results. Three equations are implemented in the constitutive model, which includes a damage index to accurately describe the plastic and damage behavior of the material. Experiments were conducted in which a cyclic loading is applied in three directions on a circular steel tube. The constitutive model was implemented in the ABAQUS FEA software through a user-defi ned subroutine. Some parameters in the constitutive model were calibrated based on the experimental and numerical results. The performance behavior of a single-layer reticulated dome under seismic motion record was investigated through the increment dynamic analysis method. The results indicate that the constitutive model is suitable for analyses and quantifying seismic damage accumulation and progressive failure and it is also benefi cial for investigating the nonlinear dynamic behavior of structures under seismic loads. The eff ect of accumulated material damage can describe large-scale structural deformation and obvious reduction in the failure limit load.

      • A Design of the Evaluation and Prediction of Power Energy Consumption of Office Buildings based on Multivariate Linear Regression

        Nie Zihang,Xuejun Yu 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.4

        In recent years, with the rapid increase of office buildings and the requirements to improve the office environment, office building energy consumption has increased significantly. That has brought great pressure to the user, environment and city power supply and demand. The electric energy consumption of office building conservation is the most important way to reduce the energy consumption. Simulation is a major method to understand about office building power consumption. At present domestic and foreign computer software simulation technology cannot work without a lot of professional parameters. And the obtained results is so professional that cannot give the management decision auxiliary. This paper presents a holistic statistical distribution instead of complex thermodynamic iterative computation model, and the analysis method. Using the mode "facing to the whole" for analysis of power energy consumption of office buildings, without more intricate parameters, and can be iterative adjusted according to the difference between measured data and the prediction.

      • Model-Based Design Methodology for Digital Up and Down Conversion of Software Defined Radio

        Nie Yang,Ge Hua,Jing Li-li,Zhao Peng-yu 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.4

        This paper proposes an efficient implementation of digital up and down conversion for Software Defined Radio (SDR) using Model-Based Design (MBD). In particular, a novel flow for designing digital up and down conversion is detailed. Using MBD, a system model is at the center of the development process, from requirement development, through design, implementation, and testing. Using MBD, code can be automatically generated for system and create test benches for system verification, which is saving time and avoiding the introduction of manually coded errors. Design example shows that the proposed method can greatly reduce the complexity of digital up and down conversion while providing the efficient and reliability of design flow.

      • Measurement Matrix Construction Algorithm for Compressed Sensing based on QC-LDPC Matrix

        NIE Yang,JING Li-li 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.2

        The measurement matrix of compressed sensing has a significant impact for sampling and reconstruction algorithm of the original signal. At present, the majority of the measurement matrix is randomly constructed, and it is difficulty for hardware implementation in the practical applications. In this paper, we use the sparse characteristic of parity- check matrix of LDPC codes, construct measurement matrix based on QC-LDPC (Quasi-cyclic low-density parity-check) matrix, which is a structural and sparse deterministic measurement matrix. The simulation results show that, the measurement matrix is proposed in this paper not only can obtain a better reconstructed image quality, but also it can reduce the complexity of hardware implementation for quasi-cyclic.

      • Identification of Aerodynamic Model CFD-Based for Gust Response Analysis

        Nie, Xueyuan,Yang, Guowei The Society for Aerospace System Engineering 2015 International Journal of Aerospace System Engineer Vol.2 No.1

        Aeroelastic gust response analysis plays an important role in design of aircrafts. For gust response analysis, frequency domain aerodynamics method has been typically used with generalized aerodynamic influence coefficient matrices at various reduced frequencies. However, it cannot be applied to the aeroservoelastic analysis, such as gust alleviation control. Time-domain state space (SS) models must be built. It attacks little attention that gust response analysis relies on continuous gust time-domain input signal in terms of its PSD function. The aim the current study is to provide a reduced-order modeling (ROM) method based on CFD to model gust responses for continuous gust responses for continuou gust inputs in time domain. The paper analyzed the gust response of AGARD445.6 wing subjected to the Dryden gust with ROMs and compared the difference between the rigid structure and elastic one. The results demonstrate that structure elastic effect effect should be considered in the design of aircraft.

      • Research on Nonlinear Vibration Characteristics of Spiral Bevel Gear

        Nie Junfeng,Yu Guangbin,Song Ye,Qu Zhigang,Zheng Minli,Zhao Xingfu 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.2

        Based on the concentrated parameters theory, a 7-freedom coupled vibration dynamic model of the spiral bevel gear transmission system is established, which includes transmission error, time-varying mesh stiffness and the tooth backlash clearance. In the model, the axial vibration, the torsion oscillation of the gear pair aroused by tooth meshing force and the lateral oscillations resulting from flexional deformation of the gear shaft are taken into account. The mesh stiffness fluctuation is developed as 5-order Fourier series and the tooth backlash clearance is fitted by 7-order polynomial function. Through the Gear method, the dynamic response of the system is obtained, and the vibration characteristics are analyzed.

        Enhanced Performance of La<sub>0.6</sub>Sr<sub>0.4</sub>Co<sub>0.2</sub>Fe<sub>0.8</sub>O<sub>3-\delta</sub> (LSCF) Cathodes with Graded Microstructure Fabricated by Tape Casting

        Nie, Lifang,Liu, Ze,Liu, Mingfei,Yang, Lei,Zhang, Yujun,Liu, Meilin The Korean Electrochemical Society 2010 Journal of electrochemical science and technology Vol.1 No.1

        $La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_{3-\delta}$ (LSCF) powders with different particle sizes, synthesized through a citrate complexation method and a gel-casting technique, are used to fabricate porous LSCF cathodes with graded microstructures via tape casting. To create porous electrodes with desired porosity and pore structures, graphite and starch are used as pore former for different layers of the graded cathode. Examination of the microstructures of the as-prepared LSCF cathode using an SEM revealed that both grain size and porosity changed gradually from the catalytically active layer (near the electrodeelectrolyte interface) to the current collection layer (near the electrode-interconnect interface). Impedance analysis showed that a 3-layer LSCF cathode with graded microstructures exhibited much-improved performance compared to that of a single-layer LSCF cathode, corresponding to interfacial resistance of 0.053, 0.11, and 0.27 $\Omega{\cdot}cm^2$ at 800, 750, and $700^{\circ}C$ respectively.

        Scholarly Periodicals and World Literature Research and Exchange

        ( Nie Zhenzhao ) 한국영어영문학회 2013 영어 영문학 Vol.59 No.3

        The early appearance of periodicals in China is largely under the influence of Western scholarship. The first Chinese language magazine Chinese Monthly Magazine (Cha Shi Su MeiYue TongJi Zhuan), for instance, was jointly issued by two Christian Protestant missionaries in 1865 in Malacca. The earliest literary periodicals appeared in the late Qing Dynasty, of which the four representative popular fiction magazines were New Fiction (Xin Xiaoshuo), Illustrated Fictions (Xiuxiang Xiaoshuo), The All-Story Monthly (Yue yue Xiao Shuo) and Forest of Fiction (Xiaoshuo Lin). As periodicals serve as the principal medium for publishing research, they have a great impact upon the process of scholarly dissemination and communication. Ever since the New Culture Movement, scholarly journals, through introducing foreign literature into China, have been playing a vital part in literary research on world literature. In order for Chinese scholarly journals to be recognized worldwide, it is of great necessity to promote academic quality and realize the professionalization and internationalization of journals.
