서묘묘(Miao-Miao Xu),윤주현(Ju-Hyun Eune) 한국HCI학회 2008 한국HCI학회 논문지 Vol.3 No.1

최근 몇 년 사이 중국의 경제가 발전함에 따라 소득의 증가로 인해 모바일폰이 급속하게 대중화되면서 더 좋은 제품을 사고자 하는 욕망이 중국 소비자들로 하여금 디자인에 큰 관심을 보이게 만들었다. 또한 세계화로 인한 다량의 문화적 홍수 속에서 중국 소비자들은 예전의 획일화된 제품보다는 자신이 좋아하는 제품을 선호하는 개인화로 이어진다. 이러한 경향은 개성적인 멀티 컬러 모바일폰과 모바일폰 디자인의 아트화로 이어졌다. 그에 반해 아직 중국 모바일폰 디자인 시장은 미성숙 됐고 identity 부족과 디자인 모방의 문제점 등이 있다. 이 연구에서는 전통 요소를 사용하여 특징 있는 모바일폰 디자인의 개발과 문화아이덴티티와 궁극적으로는 중국전통요소를 가지고 있는 퍼스널아이덴티티를 잘 혼합한 중국의 모바일폰 디자인 아이덴티티의 구축에 목적을 두고 있다. 본 연구방법으로 전통문양, 색채 등 전통요소를 살펴보고 동시에 핸드폰 디자인의 발전과정과 특징을 알아봤고 전통패턴을 활용한 모바일폰 에니메이션을 연구하고 모바일폰 디자인을 개발하였다. 중국의 전통과 이미지의 특징을 활용한 문양을 사용함으로써 전통적이면서도 가장 중국의 특징이 있는 세계적인 디자인의 개발이 가능하다. 중국 전통문양을 활용한 디자인이 부족한 실정이며 전통 문양을 사용함에 따라 모바일폰 디자인이 훨씬 더 다양하고 개성적으로 될 수 있다. 색 또한 한 가지 색만 사용하는 것이 아닌 멀티컬러를 사용할 수 있으며 이러한 디자인 사례는 시크한 이미지를 보여주며 장식적인 효과가 크다. 본 연구자는 향후에 중국적인 특징의 문양뿐만 아니라 한국, 일본의 특징 있는 문양을 활용하여 모바일폰 디자인을 개발하고자 하며 다양한 문양을 사용하여 모바일폰 브랜드를 개발하고자 한다. 또한 모바일폰 내장의 영상 애니메이션을 개발하고 싶다. A mobile phone became the practical necessities of Chinese life that can not be explained without a mobile phone as it is rapidly popularized in China in recent years. As income increases due to economic growth, so did desire to buy better products. And This desire has made consumers in China more concerned about design and consequently leads to artistic design of a mobile phone. And also this trend is getting linked to people’s personalisation in that people prefer rather to choose products they like than standardized ones in the middle of a variety of cultural inflows. This study mainly focuses on the development of the characterized mobile phone with a high class brand by use of traditional elements and of design identity of a mobile phone with Chines style that is well harmonized with cultural and personalized identity as consumers’ preferences are quite different from each other depending on each country’s culture. For this, this study investigates traditional elements such as patterns, colors and characters as well as development and features of the mobile phone design. This will also lead to the development of a mobile phone with traditional elements of China by studying utilization of design with traditional patterns. To do this, the study analyzes to research traditional patterns(Dragon, Phoenix, Peony, Lotus Flower), colors(Red, Yellow, Blue, Black, White) and historical origin and concept of characters. The study also looks into instances and personalisation of mobile phone design by analyzing literatures.

Xu Miao,Wenlong Xu,차현실,장용민,오인택,채권석,이강호 대한화학회 2017 Bulletin of the Korean Chemical Society Vol.38 No.9

Nanoparticles are very important in biomedical imaging because their imaging properties are superior to those of small molecules. They can be further functionalized for multimodal imaging through surface modification. In this study, we synthesized dye-coated ultrasmall gadolinium oxide nanoparticles [dye = fluorescein and fluorescein isothiocyanate (FITC)] in one-pot and investigated their dual imaging properties. The dye-coated gadolinium oxide nanoparticles exhibited excellent relaxometric properties suitable for T1 magnetic resonance imaging (MRI): r1 = 9.8 s−1mM−1 (r2/r1 = 2.6) for fluorescein-coated nanoparticles (davg = 1.6 ± 0.1 nm) and r1 = 12.3 s−1mM−1 (r2/r1 = 2.3) for FITC-coated nanoparticles (davg = 1.4 ± 0.1 nm), and strong photoluminescence (PL) in the green region (around 514 nm) suitable for fluorescent imaging (FI). The dye-coated nanoparticles exhibited strong fluorescence in cellular confocal images and high contrast in T1 MR images in mice, suggesting that they are potential dual T1 MRI-FI agents.

Fuzzy Logic Control Strategy for Parallel Hybrid Excavator

Miao Xu,Dingxuan Zhao,Tianyu Li 보안공학연구지원센터 2016 International Journal of Smart Home Vol.10 No.8

A 20 t parallel hybrid excavator was applied as the research object in the research. To optimize the fuel economy of the engine and maintain the balanced electric quantity of power batteries simultaneously, a fuzzy logic based strategy was proposed to control the power train of the 20t parallel hybrid excavator. The torque required by the system and the state of charge (SOC) of the capacitor were regarded as the input parameters, while the power partition coefficient K was regarded as the output parameter to design the fuzzy logic controller, so as to optimize the power output of the engine and the motor. The simulation and bench test results demonstrated that the proposed fuzzy logic based control strategy can maintain the balanced electric quantity of the capacitor while controlling the engine to be operated at the optimal output power. Meanwhile, after being optimized by the fuzzy logic, the engine reduced the fuel consumption by 8.06%. Therefore, it is concluded that this strategy is applicable to parallel hybrid excavators, accompanying with significant energy saving effect.

Xu Miao,Shuo Wang,Wenhai Sun,Yu Zhu,Chen Du,Ruixin Ma,Chengyan Wang 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2019 NANO Vol.14 No.10

It is well known that the different proportions of CuO and Cu2O in CuOx hole transfer materials have a great influence on the hole transport property as well as the device performances of perovskite solar cells (PSCs). In this paper, we changed the content of Cu2O in the film by controlling the deposition voltage during electrodeposition, and the effects of different contents of Cu2O in the films on the device were investigated for the first time. It was found that the content of Cu2O in the film reached the highest point with the deposition voltage 0.5 V, such films have the highest transmittance and carrier mobility. After assembling the device, the power conversion efficiency (PCE) of the champion device reached 13.48% under a one-sun AM 1.5G (100 mW/cm2) illumination. Furthermore, the unpackaged device based on CuOx still retained over 75% PCE after being placed in the ambient condition (30–40% humidity, 20–30 ℃) for 500 h.

Electrically actuated liquid iris.

Xu, Miao,Ren, Hongwen,Lin, Yi-Hsin Optical Society of America 2015 Optics letters Vol.40 No.5

<P>We report an adaptive iris using dielectric liquids and a radial-interdigitated electrode. A black liquid is confined by a circular gasket with a donut shape. The surrounding of the black liquid is filled with an immiscible liquid. In the relaxing state, the black liquid obtains the largest clear aperture. By applying a voltage, the surface of the black liquid is stretched by the generated dielectric force, resulting in a reduction of its aperture. For the demonstrated iris, the diameter of the aperture can be changed from 4.7??mm to 1.2??mm when the voltage is applied from 0 to 70??V(rms). The aperture ratio is 94%. Owing to the radial-interdigitated electrode, the aperture size of the iris can be effectively switched with a reasonably fast response time. The optical switch is polarization-insensitive. The potential applications of our iris are light shutters, optical attenuators, biomimicry, and wearable devices.</P>

Chattering Free Distributed Consensus Control for Attitude Tracking of Spacecraft Formation System with Unmeasurable Angular Velocity

Miao Xu,Yi-ming Fang,Jian-Xiong Li,Xiaodong Zhao 제어·로봇·시스템학회 2020 International Journal of Control, Automation, and Vol.18 No.9

In this paper, the attitude tracking control of spacecraft formation is studied when the velocities of spacecrafts are unmeasurable. Firstly, a Finite-Time Extended State Observer (FTESO) is constructed to estimate the unmeasured angular velocity and compensate the external disturbance for each spacecraft. Secondly, a chattering free distributed consensus controller which did not require inversion of Laplacian matrix is proposed based on FTESO and Integral Nonsingular Terminal Sliding Mode (INTSM). It is proved that the proposed consensus controller can realize finite-time attitude tracking control of spacecraft by the Lyapunov stability theory. Finally, a simulation example with one leader and four followers is given. The simulation results show that the proposed consensus controller can eliminate system chattering, and provide fast finite-time convergence performance and high precision Tracking.
