현대와 전통의 교착(交錯)과 융합 : 漫說: 조선족 작곡가 權吉浩의 음악창작

가오, 웨이 지 漢陽大學校 音樂硏究所 1993 音樂論壇 Vol.7 No.-

7년 전, 내가 제4차 전국음악작품 콩쿨 평심위원으로 있었을 때, 처음으로 조선족 청년작곡가 권길호(권길호)의 작품을 듣게 되었다. 그때 상해음악학원의 이름없는 작곡과 학생이었던 권길호가 보내온 작품은 피아노 조곡 「장단의 조합」이었다. 「장단의 조합」,(중국인들에겐 "장단"이란 단어가 길고 짧음으로 밖에 이해되지 않는다-번역자)이 괴상한 표제의 곡을 받아 보면서 처음엔 모두들 "선봉파"식의 추상적인 작품이 아닌가고 생각하였다. 사실 이 작품은 농후한 조선족 음악쟝르와 민속적인 정감이 차 넘친 아름다운 곡이었다. 그 당시 이 작품은 청년 피아노연주가 리건의 현장연주 후 강렬한 반응을 일으켰는데, 전체 평심위원들과 관람자들을 번쩍 놀래웠다고 보도되었다. 하여 이 작품은 그번 콩클에서 제일 첫자리로 수석 1등상을 타게 되었고, 그때로부터 권길호(권길호)라는 이 이름을 기억하게 되었다.

Dynamic simulation and control of a triple column process for dimethyl carbonate- methanol separation

Hong-Mei Wei,Qiang Gao,Wei-zhou Jiao,Wei Wei 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.12

Separation of dimethyl carbonate/methanol azeotropic mixture by using pressure-swing distillation processhas been a hot-point in the study of the synthesis process of dimethyl carbonate by urea methanolysis method. Thisstudy updates the work of the writers (Ind.Eng.Chem.Res,2013,52,11463-11478), which explores the dynamic controlstructure of the three-column separation dimethyl carbonate (DMC)/methanol (MeOH) process from an actual pilotplant. At first, the conventional DMC/MeOH separation process in the pilot test of the DMC synthesis process throughalcoholysis of urea was described in detail. Then an optimized control structure for the entire DMC/MeOH separationunit was obtained by implementing a general heuristic design procedure. An economic analysis was performed to evaluatethe optimized process. Finally, three dynamic control schemes were proposed and evaluated with several large disturbances,an improved control scheme CS3, using the multiplier blocks “QR1/F1” and “RR1” in T1, “QR1/F1” and “R/F”in both T2 and T3, outperformed CS1 and CS2 by maintaining the product specification in each column.

ACCURACY OF LAMOST DR1 STELLAR PARAMETERS

GAO, HUA,ZHANG, HUA-WEI,XIANG, MAO-SHENG,HUANG, YANG,LIU, XIAO-WEI,LUO, A-LI,ZHANG, HAO-TONG,WU, YUE,ZHANG, YONG,LI, GUANG-WEI,DU, BING The Korean Astronomical Society 2015 天文學論叢 Vol.30 No.2

We adopt the PASTEL catalog combined with SIMBAD radial velocities as a testing standard to validate the stellar parameters (effective temperature $T_{eff}$, surface gravity log g, metallicity [Fe/H] and radial velocity $V_r$) from the first data release (DR1) of The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. After applying data reduction and temperature constraints to the sample obtained by cross-identification, we compare the stellar parameters from DR1 and PASTEL. The results show that the DR1 results are reliable under certain conditions. We derive a dispersion of 110 K, 0.19 dex, 0.11 dex and $4.91kms^{-1}$ in specified effective temperature ranges, for $T_{eff}$, log g, [Fe/H] and $V_r$ respectively. Systematic errors are negligible except for those of $V_r$. In addition, for stars with PASTEL [Fe/H] < -1:5, the metallicities in DR1 are systematically higher than those in PASTEL.

TIGHT TOUGHNESS CONDITION FOR FRACTIONAL (g, f, n)-CRITICAL GRAPHS

Gao, Wei,Liang, Li,Xu, Tianwei,Zhou, Juxiang Korean Mathematical Society 2014 대한수학회지 Vol.51 No.1

A graph G is called a fractional (g, f, n)-critical graph if any n vertices are removed from G, then the resulting graph admits a fractional (g, f)-factor. In this paper, we determine the new toughness condition for fractional (g, f, n)-critical graphs. It is proved that G is fractional (g, f, n)-critical if $t(G){\geq}\frac{b^2-1+bn}{a}$. This bound is sharp in some sense. Furthermore, the best toughness condition for fractional (a, b, n)-critical graphs is given.

Wind velocity simulation of spatial three-dimensional fields based on autoregressive model

Wei-cheng Gao,Yan-lei Yu 한국풍공학회 2008 Wind and Structures, An International Journal (WAS Vol.11 No.3

This paper adopts autoregressive (AR) model to simulate the wind velocity of spatial threedimensional fields in accordance with the time and space dependent characteristics of the 3-D fields. Based on the built MATLAB programming, this paper discusses in detail the issues of the AR model deduced by matrix form in the simulation and proposes the corresponding solving methods: the overrelaxation iteration to solve the large sparse matrix equations produced by large number of degrees of freedom of structures; the improved Gauss formula to calculate the numerical integral equations which integral functions contain oscillating functions; the mixed congruence and central limit theorem of Lindberg-Levy to generate random numbers. This paper also develops a method of ascertaining the rank of the AR model. The numerical examples show that all those methods are stable and reliable, which can be used to simulate the wind velocity of all large span structures in civil engineering.

Structural evaluation of an existing steel natatorium by FEM and dynamic measurement

Wei Liu,Wei-Cheng Gao,Yi Sun,Yan-Lei Yu 국제구조공학회 2009 Structural Engineering and Mechanics, An Int'l Jou Vol.31 No.5

Based on numerical and experimental methods, a systematic structural evaluation of a steel natatorium in service was carried out in detail in this paper. Planning of inspection tasks was proposed firstly according to some national codes in China in order to obtain the economic and reliable results. The field visual inspections and static computation were conducted in turn under in-service environmental conditions. Further a three-dimensional finite element model was developed according to its factual geometry properties obtained from the field inspection. An analytical modal analysis was performed to provide the analytical modal properties. The field vibration tests on the natatorium were conducted and then two different system identification methods were used to obtain the dynamic characteristics of the natatorium. A good correlation was achieved in results obtained from the two system identification methods and the finite element method (FEM). The numerical and experimental results demonstrated that the main structure of the natatorium in its present status is safe and it still satisfies the demand of the national codes in China. But the roof system such as purlines and skeletons must be removed and rebuilt completely. Moreover the system identification results showed that field vibration test is sufficient to identify the reliable dynamic properties of the natatorium. The constructive suggestion on structural evaluation of the natatorium is that periodic assessment work must be maintained to ensure the natatorium’s safety in the future.

BCC-DPSO Algorithm for Task Scheduling on NOC

Wei Gao,Yubai Li,Song Chai,Jian Wang 보안공학연구지원센터 2014 International Journal of Grid and Distributed Comp Vol.7 No.5

In this paper, a BCC-DPSO scheduling algorithm is proposed to solve multi-objective optimization problem for task scheduling on Network-on-Chip (NoC). In our proposal, the relative advantage of the solution is evaluated by calculating its efficiency using BCC model in Data Envelopment Analysis (DEA), and the referred-time method is introduced to rank the BCC-efficient solution. Moreover, a sub-swarm strategy is adopted to reduce the high computational requirement introduced by the DEA. There are four sub-swarms, each of which optimizes one of four observed metrics, namely makespan, energy, link load and workload balance. Meanwhile, the speed vector updating formulation is modified to comply with the sub-swarm strategy. By conducting comparative simulations, the results show that our proposal produces more efficient schedule solution than other multi-objective Particle Swarm Optimization (PSO).

Precision Nanometrology and its Applications to Precision Nanosystems

Wei Gao 한국정밀공학회 2005 International Journal of Precision Engineering and Vol.6 No.4

In this paper, a new field of metrology called "precision nanometrology" is presented. The "precision nanometrology" is the result of evolutions of the traditional "precision metrology" and the new "nanometrology". "Precision nanometrology" is defined here as the science of dimensional measurement and motion measurement with 100 ㎚ to 0.1 ㎚ resolution/uncertainty within a range of micrometer to meter. The definition is based on the fact that nanometrology in nanoengineering and the precision industries, such as semiconductor industry, precision machine tool industry, precision instrument industry, is not only concerned with the measurement resolution and/or uncertainty but also the range of measurement. It should also be pointed out that most of the measurement objects in nanoengineering have dimensions larger than I micrometer. After explaining the definition of precision nanometrology, the paper provides several examples showing the critical roles of precision nanometrologv in precision nanosystems, including nanometrology system, nanofabrication system, and nanomechatronics system.
