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.

Nie, Riming,Yun, Hyun-sung,Paik, Min-Jae,Mehta, Aarti,Park, Byung-wook,Choi, Yong Chan,Seok, Sang Il Wiley-VCH 2018 ADVANCED ENERGY MATERIALS Vol.8 No.7

<P> Although antimony sulfoiodide (SbSI) exhibits very interesting properties including high photoconductivity, ferroelectricity, and piezoelectricity, it is not applied to solar cells. Meanwhile, SbSI is predominantly prepared as a powder using a high-temperature, high-pressure system. Herein, the fabrication of solar cells utilizing SbSI as light harvesters is reported for the first time to the best of knowledge. SbSI is prepared by solution processing, followed by annealing under mild temperature conditions by a reaction between antimony trisulfide, which is deposited by chemical bath deposition on a mesoporous TiO<SUB>2</SUB> electrode and antimony triiodide, under air at a low temperature (90 °C) without any external pressure. The solar cells fabricated using SbSI exhibit a power conversion efficiency of 3.05% under standard illumination conditions of 100 mW cm<SUP>-2</SUP>. </P>

Capacitor voltage feedforward decoupling control based on third harmonic injection modulation for five-level active neutral point clamped converter

Nie, Ziling,Ye, Weiwei,Zhu, Junjie,Xu, Jie The Korean Institute of Power Electronics 2020 JOURNAL OF POWER ELECTRONICS Vol.20 No.6

For the five-level active neutral point clamped (5L-ANPC) converter, the coupling problem between the DC-link capacitor voltages and flying-capacitor (FC) voltages will increase the capacitor voltage fluctuations. The capacitor voltage fluctuations and current harmonics of the space vector pulse width modulation (SVPWM) are less than those of the sinusoidal pulse width modulation (SPWM), because the maximum linear modulation index of the SVPWM is higher than that of the SPWM. However, SVPWM has difficulty in realizing the decoupling control of the capacitor voltages, and the computation complexity of SVPWM is much higher than that of SPWM. This paper proposes a third harmonic injection modulation algorithm for the 5L-ANPC converter. The proposed algorithm injects the third harmonic into the modulation waves of SPWM, which makes the maximum linear modulation index of SPWM the same as that of SVPWM, to reduce the capacitor voltage fluctuations and current harmonics. The calculation of the third harmonic only requires a standard sorting algorithm and a simple linear operation; thus, it is easy to implement. Based on the third harmonic injection modulation algorithm, two variables are introduced to control the neutral point (NP) current and the FC current. And the two variables are used to feedforward compensate the modulation waves, realizing the decoupling control of the capacitor voltages. The proposed decoupling control method can further reduce the capacitor voltage fluctuations. Experimental results are presented to verify the validity of the proposed algorithm.

Nie, H.T.,Wan, Y.J.,You, J.H.,Wang, Z.Y.,Lan, S.,Fan, Y.X.,Wang, F. Asian Australasian Association of Animal Productio 2015 Animal Bioscience Vol.28 No.8

This research aimed to define the energy requirement of Dorper and Hu Hybrid $F_1$ ewes 20 to 50 kg of body weight, furthermore to study energy requirement changes with age and evaluate the effect of age on energy requirement parameters. In comparative slaughter trial, thirty animals were divided into three dry matter intake treatments (ad libitum, n = 18; low restricted, n = 6; high restricted, n = 6), and were all slaughtered as baseline, intermediate, and final slaughter groups, to calculate body chemical components and energy retained. In digestibility trial, twelve ewes were housed in individual metabolic cages and randomly assigned to three feeding treatments in accordance with the design of a comparative slaughter trial, to evaluate dietary energetic values at different feed intake levels. The combined data indicated that, with increasing age, the net energy requirement for maintenance ($NE_m$) decreased from $260.62{\pm}13.21$ to $250.61{\pm}11.79kJ/kg^{0.75}$ of shrunk body weight (SBW)/d, and metabolizable energy requirement for maintenance (MEm) decreased from $401.99{\pm}20.31$ to $371.23{\pm}17.47kJ/kg^{0.75}$ of SBW/d. Partial efficiency of ME utilization for maintenance ($k_m$, 0.65 vs 0.68) and growth ($k_g$, 0.42 vs 0.41) did not differ (p>0.05) due to age; At the similar condition of average daily gain, net energy requirements for growth ($NE_g$) and metabolizable energy requirements for growth ($ME_g$) for ewes during late fattening period were 23% and 25% greater than corresponding values of ewes during early fattening period. In conclusion, the effect of age upon energy requirement parameters in the present study were similar in tendency with previous recommendations, values of energy requirement for growth ($NE_g$ and $ME_g$) for Dorper and Hu crossbred female lambs ranged between the NRC (2007) recommendation for early and later maturating growing sheep.

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.

Nie, ShangQi,Ma, Biao,Song, Jeho The International Promotion Agency of Culture Tech 2020 International Journal of Advanced Culture Technolo Vol.8 No.3

The physique and health status of Chinese college students have received a generous concern in recent years. The physical condition of Chinese college students is not good and this phenomenon is especially obvious among female college students, which has been an disputable fact. This study starts from exercise intervention to study the concrete influence of taijiquan (a kind of traditional Chinese shadow boxing) and five-animal exercises on human body balance ability; the study uses experimental apparatus to measure the specific impact of exercise intervention on human body balance ability; meanwhile, the study also applies data analysis to longitudinally study whether the two studied sports items affect body balance, and whether there is difference in terms of the influence of two sports items on human body balance ability. The conclusions are as follows: firstly, 24-style taijiquan and five-animal exercises can improve ankle muscle strength, and the focus and degree of the improvement are different; secondly, five-animal exercises have a better improvement effect on the flexor and extensor muscles of ankle joint and 24-style taijiquan is in the second place. Moreover, compared with 24-style taijiquan, there is no significant difference in terms of the improvement caused by five-animal exercises; thirdly, 24-style taijiquan has a better effect on the improvement of internal rotation and evertors muscle strength. Compared with 24-style taijiquan, five-animal exercises have no significant difference in terms of the improvement degree.

Enhanced Performance of La_0.6Sr_0.4Co_0.2Fe_0.8O_3-\delta (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.

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.
