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.

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.

Packet Scheduling with QoS and Fairness for Downlink Traffic in WiMAX Networks

Nie, Wei,Wang, Houjun,Park, Jong-Hyuk Korea Information Processing Society 2011 Journal of information processing systems Vol.7 No.2

The IEEE 802.16 standard is supposed to provide a wide-range broadband wireless service, but it leaves the implementation of the wireless resource scheduler as an open issue. We have studied the scheduling problem and propose a two level scheduling (TLS) scheme with support for quality of service and fairness guarantees for downlink traffic in a WiMAX network. A central controller Base Station has a number of users, and each mobile subscriber station has different channel conditions. The same mobile subscriber station may have different service requirements at different times in the WiMAX network. Based on OPNET simulation, the results show our scheduling algorithm can increase the network throughput, maintain relative fairness, and lower delay over the round robin and weighted round robin algorithms.

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.

A Quality-Oriented Data Collection Scheme in Vehicular Sensor Networks

Nie, Wendi,Lee, Victor C. S.,Niyato, Dusit,Duan, Yaoxin,Liu, Kai,Nutanong, Sarana IEEE 2018 IEEE Transactions on Vehicular Technology VT Vol.67 No.7

<P>Considerable research attention has been dedicated to vehicular sensor networks (VSNs) because of its great potential in traffic monitoring. By taking advantage of sensors embedded in vehicles, a VSN harvests data while vehicles are traveling along the roads and then updates the collected data to the infrastructure to support the intelligent transportation system (ITS) applications. To meet the data collection requirements of different ITS applications, a huge number of update packets are generated, which may exhaust the available wireless communication bandwidth. To improve the efficiency of utilization of wireless bandwidth, in this study, we propose a <I> quality-oriented data collection</I> scheme, which aims to effectively support both the accuracy and real-time requirements stipulated by ITS applications while reducing communication overhead. We formulate a <I>minimized communication overhead (MCO)</I> problem and propose two algorithms, <I>mixed-integer linear programming (MILP)</I> and <I>deviation-detection (DD)</I>, to solve the MCO problem. MILP can obtain the optimal solution by having all the data collected by every vehicle, while DD could achieve an efficient solution without this impractical assumption. We conducted extensive experiments by using SUMO to simulate vehicle traces in freeway and downtown environments. The experimental results have demonstrated the effectiveness of the proposed solutions.</P>

Theoretical Demonstration of the Ionic Barristor

Nie, Yifan,Hong, Suklyun,Wallace, Robert M.,Cho, Kyeongjae American Chemical Society 2016 Nano letters Vol.16 No.3

<P>In this Letter, we use first-principles simulations to demonstrate the absence of Fermi-level pinning when graphene is in contact with transition metal dichalcogenides (TMDs). We find that formation of either an ohmic or Schottky contact is possible. Then we show that, due to the shallow density of states around its Fermi level, the work function of graphene can be tuned by ion adsorption. Finally we combine work function tuning of graphene and an ideal contact between graphene and TMDs to propose an ionic barristor design that can tune the work function of graphene with a much wider margin than current barristor designs, achieving a dynamic switching among p-type ohmic contact, Schottky contact, and n-type ohmic contact in one device.</P>

Nie, Chengrong,Yang, Xing,Niazi, Nabeel Khan,Xu, Xiaoya,Wen, Yuhui,Rinklebe, Jö,rg,Ok, Yong Sik,Xu, Song,Wang, Hailong Elsevier 2018 CHEMOSPHERE - Vol.200 No.-

<P><B>Abstract</B></P> <P>In the current study, we conducted a field experiment using the test plant, <I>Brassica chinesis</I> L. (pak choi), to investigate the effect of sugarcane bagasse-derived biochar on the bioavailability of cadmium (Cd), copper (Cu) and lead (Pb), and the health of soil microbiota in a contaminated soil. Biochar application significantly (<I>P</I> < 0.05) increased pak choi yield. Bioavailability of heavy metals to plant shoots and roots decreased with increasing biochar application rates (at 0, 1.5, 2.25 and 3.0 t ha<SUP>−1</SUP>). Sequential extraction of the biochar-treated and -untreated soil revealed that exchangeable Cd reduced whereas organically-bound fraction increased with increasing biochar rate. The labile fractions of Cu and Pb decreased, but the residual fraction increased in biochar-treated soils compared to the control. Urease, catalase and invertase activities, and the populations of bacteria and actinomycetes were significantly enhanced, whereas fungi population declined in biochar-treated soils. This study highlights that sugarcane bagasse biochar has the potential to support the remediation of soils contaminated with heavy metals, and as such can improve the yield and quality of agricultural crops.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Sugarcane bagasse biochar amendment reduced availability of Cd, Cu and Pb in soils. </LI> <LI> Heavy metals were less labile in the biochar-treated soils. </LI> <LI> Biochar amendment induced an increase in soil enzyme and microbial activity. </LI> <LI> Edible part of pak choi was safer for human consumption after biochar amendment. </LI> </UL> </P>

Nie, Zhaogang,Zhang, Jiahua,Zhang, Xia,Lim, Ki-Soo Cambridge University Press (Materials Research Soc 2009 Journal of materials research Vol.24 No.5

<P>High-quality SrAl12O19:Pr<SUP>3+</SUP> nanodisks and nanoplates were fabricated via a new processing technique based on a modified polymer steric entrapment method. Serious agglomeration and large particle size distribution of final products, which usually occurred in the conventional method, were eliminated completely. The effects of new synthetic processes on the morphology, crystallization, and yield of products and the relevant mechanisms were discussed. As far as we know, SrAl12O19:Pr<SUP>3+</SUP> nanodisks with mean diameter ∼60 nm and thickness between 5 and 10 nm were successfully synthesized for the first time by this low-cost technique. The new synthetic method may provide a general route to synthesize other refractory mixed-oxide nanocrystals. Photon cascade emission involving transitions <SUP>1</SUP>S0-<SUP>1</SUP>I6 followed by <SUP>3</SUP>P0-<SUP>3</SUP>H4 in SrAl12O19:1% Pr<SUP>3+</SUP> nanodisks was investigated. Size-effect-induced blue shift of the 4<I>f</I>5<I>d</I> states of Pr<SUP>3+</SUP> was observed in SrAl12O19:1% Pr<SUP>3+</SUP> nanodisks, in which the quantum efficiency was preserved, as in the bulk counterparts.</P>

Norm Noncompliance and Norm Diffusion: Free Trade Norms among the United States, European Union, and China

Nie Wenjuan 경남대학교 극동문제연구소 2021 ASIAN PERSPECTIVE Vol.45 No.4

Would existing norms be vulnerable to degeneration due to the noncompliance behavior of some members, especially that of norm entrepreneurs? Standard accounts of norm studies focus on the negative influences of norm noncompliance on norm diffusion. This article starts with a critical thinking about norm noncompliance and argues that norm noncompliance, as well as norm compliance, constitutes a normal and necessary part of our social system. It develops hypotheses on why and how norm noncompliance leads to norm diffusion. To illustrate this argument, it takes free trade norms as a case to explore the different attitudes held by the United States, European Union (EU), and China. China has been motivated by US noncompliance behaviors to take the lead in diffusing free trade norms, while the EU tries to prevent China from taking the championship, which combined have promoted the diffusion of free trade norms.

Nie, Riming,Mehta, Aarti,Park, Byung-wook,Kwon, Hyoung-Woo,Im, Jino,Seok, Sang Il American Chemical Society 2018 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.140 No.3

<P>The use of divalent chalcogenides and monovalent halides as anions in a perovskite structure allows the introduction of 3<SUP>+</SUP> and 4<SUP>+</SUP> charged cations in the place of the 2<SUP>+</SUP> metal cations. Herein we report for the first time on the fabrication of solar cells exploiting methylammonium antimony sulfur diiodide (MASbSI<SUB>2</SUB>) perovskite structures, as light harvesters. The MASbSI<SUB>2</SUB> was prepared by annealing under mild temperature conditions, via a sequential reaction between antimony trisulfide (Sb<SUB>2</SUB>S<SUB>3</SUB>), which is deposited by the chemical bath deposition (CBD) method, antimony triiodide (SbI<SUB>3</SUB>), and methylammonium iodide (MAI) onto a mesoporous TiO<SUB>2</SUB> electrode, and then annealed at 150 °C in an argon atmosphere. The solar cells fabricated using MASbSI<SUB>2</SUB> exhibited power conversion efficiencies (PCE) of 3.08%, under the standard illumination conditions of 100 mW/cm<SUP>2</SUP>.</P> [FIG OMISSION]</BR>
