Two-sided Matching Decision under Uncertain Score Environment

Qi Yue 보안공학연구지원센터 2014 International Journal of Multimedia and Ubiquitous Vol.9 No.12

In order to solve the two-sided matching problem based on uncertain score information, a new method is presented. Firstly, the description of the two-sided matching problem with uncertain scores is given. Secondly, the satisfaction degrees of each agent towards the agents on the other side are calculated. A multi-objective optimization model to maximize the satisfaction degrees of agents is set up. Considering the important degree of each agent in each side, the multi-objective optimization model is transformed into a bi-objective optimization model. Furthermore, the bi-objective optimization model is transformed into a single-objective model by using the linear weighted method. The matching alternative can be determined by solving the single-objective model. Lastly, an example is given to illustrate the validity of the proposed method.

AlCrN and TiAlSiN coatings were deposited on the surface of 30CrMnSi steel and cemented carbide YT15 by multi-arc ion plating technique. A scanning electron microscopy was used to observe the surface morphologies of both coatings. The reciprocating sliding tests of AlCrN and TiAlSiN coating were performed to investigate the friction coefficients and the wear mechanisms of both coatings were analyzed as well. Dry machining tests on 30CrMnSi hardened steel were carried out with the AlCrN and TiAlSiN coated tools on a CA6140A lathe. The effects of cutting speed on cutting forces and cutting temperatures of AlCrN and TiAlSiN coated tools were obtained and analyzed. The microcosmic micrographs of wear areas of both coated tools were observed and investigated by scanning electron microscope and energy dispersive spectrum. The results show that the hardness and bonding strength of AlCrN coating are higher than that of TiAlSiN coating, while the friction coefficient of AlCrN coating is lower than that of TiAlSiN coating. Both the cutting force and cutting temperature of AlCrN coated tool are lower than TiAlSiN coated tool. The time required for the bluntness of the AlCrN coated tool is approximately 33.3% longer than that of the TiAlSiN coated tool, and the main wear mechanisms of both tools are mainly crater wear, diffusion wear and oxidation wear.

Effects of a novel mold inhibitor specifically for bamboo, on the properties of composite products have been confirmed in this study. The mechanical and dimensional stability properties of bamboo fiber-based composites (BFBCs) from different bamboo species were also investigated. The results showed that Burmanica Gamble possessed the highest values of modulus of elasticity (MOE) of 33.2 GPa, modulus of rupture (MOR) of 286.9 MPa, compressive strength of 182.6 MPa and shear strength of 24.0 MPa. By contrast, Phyllostochys heterocycla among all of species showed the lowest MOE of 16.3 GPa, MOR of 170.3 MPa and compressive strength of 128.9 MPa were the lowest among all of species. Moreover, there is a remarkable variation in the swelling and water absorption between the samples with 4 h and 28 h water immersion treatment, especially Phyllostachys iridenscens. Overall, the results suggested that TCIT (Tebuconazole and 3(2H)-isothiazolone) had no significant effect on the mechanical properties compared with the control condition, and it would be utilized as an antimould of BFBCs manufacturing.

( Yue Qi ),전우석,장재혁,김남훈 韓國木材工學會 2016 한국목재공학회 학술발표논문집 Vol.2016 No.2

국내 목재시장은 83% 이상을 수입재에 의존하고 있다. 2050년까지 국산재 점유율 50%를 목표로 하고 있는 우리나라로서는 유용수종 및 속성수의 개발이 중요하다. 특히, 국내산 참오동나무는 다른 수종들에 비해 생장속도가 약 3배 이상 빠른 속성수이며, 비중이 0.30 정도로 매우 작기 때문에 원료의 확보 및 미세섬유화가 우수할 것으로 생각되는 유망 자원이라 할 수 있다. 따라서 본 연구에서는 국내에 자생하고 있는 참오동나무의 해부 및 마세섬유화 특성을 평가하기 위해 수간, 가지, 뿌리의 각 부위별로 비교·분석하였다. 그 결과, 수간과 가지재에서는 뚜렷한 생장륜과 함께 고립관공이 관찰되었지만, 뿌리재에서는 비교적 뚜렷하지 않은 생장륜과 함께 고립관공과 방사복합관공이 관찰되었다. 도관의 개수와 직경 그리고 방사조직의 개수, 폭, 높이는 뚜렷한 차이를 보였지만, 섬유 길이는 유사한 값을 보였다. 미세섬유화 과정에서 연속식 분쇄 중 동일 중량을 분쇄하였음에도 가지재 수간 및 뿌리재에 비하여 비교적 빠른 속도로 미세섬유가 제조 되었다. 섬유의 미세화 정도를 간접적으로 평가할 수 있는 여수도 측정결과, 가지재가 다른 두 부위에 비해 여수시간이 길었다. SEM 관찰 결과 세 부위 모두 큰 차이는 보이지 않았으나, 가지재에서 섬유간 재응집 현상이 관찰되는 빈도가 상대적으로 적었다.

The Tacit Knowledge of Media Communication to University Sport and Global Education Developments

( Qi Yue Chen ) 한국체육학회 2015 국제스포츠과학 학술대회 Vol.2015 No.1

Purpose: Tacit knowledge is contained in physical education teaching contents and media communication, carried by students, embodied in sports skills. This study analyzes the influence on university students` humanistic literacy during the process of media communication in the perspective of Communication Study, and takes an example of commentary and reports of classical Beijing Olympic shooting(Emmons) to explore the containing education function. Method: It mainly uses the four research methods of literature, case, questionnaires and logical analysis. Through a random survey on 200 university students in The Capital University of Physical Education and Sports, Peking University, Communication University of China, The Beijing Second Language Institute, the related data are obtained that provides the data are obtained that provides the data protection for the research. Result: In the activities of the dissemination and commentary, the some audience`s psychological needs should be corresponded and unified with the fresh, fun, proximity, time and humane owned by news facts and news itself, which constitutes the value performance of sports live commentary and reports. The achievement of education role of media and communication is mainly reflected in three progressive levels of "Emotional Appearance", "Emotion Touch" and "Emotional Thought". Take an example of "Emmons`s last shot of 4.4 Ring, so championship changed hands and history repeated itself to analyze its emotional grasping and education functions in the sports commentary and reports. The results show that the cultivation of humanistic literacy and the tactile effect of subtle media influence are much greater than the theoretical sermon. The university students` humanistic literacy is mainly expressed in the aspects of ideal pursuit, aesthetic taste,value orientation and others. The spread of media has an important revelation for students` education of humanistic literacy. Conclusion: Firstly, for university students the education should combine reason and feelings, while the tactile effect of feeling and learning is stronger than sermon, and this subtle influence of education function is immeasurable. Secondly, Tacit knowledge`s transfer in media communication mainly includes such two forms as "apprentice system" and the "explicit transformation" of tacit knowledge. Thirdly, universities need to focus on students` humanistic literacy,while it must firstly cultivate university students to have harmonious development for a sound personality, mentality and physique. Fourth, guide students how to properly treat a variety of pros and grow and obtain the experience from failure. Fifth, when encouraging faster,stronger and higher Olympic spirit, it should pay attention to the grasp and interpretation of human nature. This will promote the quality education that bothers the students education for long term and promote the education process that uses "felling" to influence people.

Utilization of electron beam to modulate electron injection over Schottky barrier

Qi Zhang,Junjie Qi,Yunhua Huang,Huifeng Li,Xin Li,Ruoshui Wang,Yue Zhang 한국물리학회 2011 Current Applied Physics Vol.11 No.3

Modulation of electron injection over Schottky barrier was realized by employing electron beam irradiation on the metal/ZnO-nanowire contact. The structure revealed a good response to the illumination at a scanning frequency of 0.1 Hz, which can be enhanced by increasing bias and decreased with the increase of electron beam energy. These phenomena can be attributed to the Schottky barrier formed at the metal/ZnO-nanowire interface which limits the electron transport across the contact. The electron beam irradiation gives rise to high efficiency of electron injection over the barrier, while the interplay between charge discreteness, coherent scattering, and Coulomb interaction may reduce the conductivity.

The diameter of TW vessels was larger than thatof OW and LW vessels. The most distinctive feature of TW fibers was the presence of a gelatinous layer (G-fiber). The cell wall of TW fibers was nearly three times as thick as that of OW and LW. TW differed from OW and LWin density, X-ray diffraction pattern and shear and compressive strengths. The results obtained in this study showedclear differences in the anatomical and physical properties of TW, OW and LW of Paulownia coreana branch woods.

Two-sided Matching Decision with Two-granularity Uncertain and Incomplete Linguistic Terms

Yue Qi 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.2

With respect to the two-sided matching problem, where the agents’ preferences are in the format of two-granularity uncertain and incomplete linguistic terms, a matching method is presented. Some definitions on uncertain linguistic term and 2-tuple are firstly given. The two-sided matching problem with two-granularity uncertain and incomplete linguistic terms is described. Then, uncertain and incomplete linguistic term matrixes are transformed into 2-tuple matrixes. Furthermore, a multi-objective optimization model is developed by using the extended 2-tuple weighted average. By using the 2-tuple arithmetic mean, the normalization method and the linear weighted method, the multi-objective optimization model can be converted into a single-objective optimization model. By solving the optimization model, the matching alternative can be obtained. A matching example illustrates the feasibility and effectiveness of this method.
