Fuzzy logic based control has recently been proposed for regulating the properties of magnetorheological (MR) dampers in an effort to reduce vibrations of structures subjected to seismic excitations. So far, most studies showing the effectiveness of these algorithms have focused on the use of a single MR damper. Because multiple dampers would be needed in practical applications, this study aims to evaluate the effects of multiple individually tuned fuzzy-controlled MR dampers in reducing responses of a multi-degree-of-freedom structure subjected to seismic motions. Two different fuzzy-control algorithms are considered, a traditional controller where all parameters are kept constant, and a gain-scheduling control strategy. Different damper placement configurations are also considered, as are different numbers of MR dampers. To determine the robustness of the fuzzy controllers developed to changes in ground excitation, the structure selected is subjected to different earthquake records. Responses analyzed include peak and root mean square displacements, accelerations, and interstory drifts. Results obtained with the fuzzy-based control schemes are compared to passive control strategies.
Plastic collapse of tapered, tip-loaded cantilevered beams
Wilson, James F.,El-Esnawy, Nayer A. Techno-Press 2000 Structural Engineering and Mechanics, An Int'l Jou Vol.9 No.6
The plastic collapse loads and their locations are predicted for a class of tapered, initially curved, and transversely corrugated cantilevered beams subjected to static tip loading. Results of both closed form and finite element solutions for several rigid perfectly plastic and elastic perfectly plastic beam models are evaluated. The governing equations are cast in nondimensional form for efficient studies of collapse load as it varies with beam geometry and the angle of the tip load. Static experiments for laboratory-scale configurations whose taper flared toward the tip, complemented the theory in that collapse occurred at points about 40% of the beams length from the fixed end. Experiments for low speed impact loading of these configurations showed that collapse occurred further from the fixed end, between the 61% and 71% points. The results may be applied to the design of safer highway guardrail terminal systems that collapse by design under vehicle impact.
Atmosphere and the Foreign Language Classroom
Wilson, Tom 한국영어어문교육학회 1996 영어어문교육 Vol.2 No.-
In writing this paper, it is my hope that I might be able to provide the Korean foreign language teacher with a unique perspective; specifically, the approach taken by one native speaker of English when teaching Korean foreign language students. Although I will briefly touch upon one language theory, this paper is not intended to be theorotical. Neither is it reseach heavy. It is not my aim to compile and rephrase the words of fifty other academic scholars or language theorists, both living and dead. This paper is intended to raise awareness, provide insight, and open avenues of discussion and debate, by way of my own personal teaching experience. In other words, this paper is meant to be accessible, practical and, above all, similar in style to my teaching approach--user friendly. As I must constrain myself in this paper, let me limit my subject matter to one aspect of language teaching which I consider to be of the utmost importance, but which I suspect is often overlooked and neglected, if it is given any consideration at all--classroom atmosphere. Or, more appropriately, the teacher's role in creating a classroom atmosphere that is more conducive to language acquisition. The reason I feel that classroom atmosphere is often neglected is because it is rather intangible, unlike the other more "concrete" (and hence more relevant, atleast in the teacher's eyes) teaching obligations such as lesson plans, grading, testing, etc. These are all things that can be seen, quantified, or have measurable result. But how does one measure or quantify atmosphere, much less go about "creating" it? Precisely because it is so intangible, rather elusive, the tendency may be to render it insignificant. At best, atmosphere can only be measured subjectively, relying on the opinion and impressions and opinions of the students are highly relevant. If the students feel comfortable, then they are more willing participants.

In these brief remarks to the second SMU-UTS Joint Seminar, I want to give some reflections on the changing direction of Unification Theology in the age of the FFWPU.
University and Industry Linkages in Brazil: Some Preliminary and Descriptive Results
Wilson Suzigan,Eduardo Albuquerque,Renato Garcia,Marcia Rapini 서울대학교 경제연구소 2009 Seoul journal of economics Vol.22 No.4
The main aim of this paper is to exam the patterns of universityindustry linkages in Brazil. To do that, it is presented some preliminary and descriptive results from two main sources, the database from the Brazilian Research Council (CNPq), and some descriptive data from the Brazilian university survey. Even with these data was not enough to present and to discuss the pattern, it can show some interactions between university and firms in Brazil, especially the role played by the university in the creation and diffusion of knowledge among firms. The main results show that Brazilian university can play an important role among firms, not only by the rendering of services, which is a way to transfer codified knowledge, but also by the establishment of cooperative research, in which the knowledge involved are more tacit and requires close interaction between universities and firms.
The Cosmos a Garden : The Unification Environmental Vision
Wilson, Andrew 선문대학교 통일신학연구원 1997 통일신학연구 Vol.2 No.1
우주적 동산: 환경에 대한 통일원리적 비전 신종교로서의 통일교회는 고도의 기술과 환경 위기의 시대에 출현하였다. 통일교회의 창시자인 문선명 목사는 자연에 대한 인간의 태도와 환경오염의 문제를 신중하게 생각하고 언급한다. 통일원리는 창세기 1장 28절의 만물을 다스리라는 언급에 대해 독특한 해석을 한다. 즉 인간의 만물에 대한 다스림, 즉 주관은 인간이 하나님으로부터 사랑을 받아 만물에게 전하는 종적 사랑의 질서 속에서 가능하다는 것이다. 그리고 존재 만물은 개체적 목적뿐만 아니라 전체적 목적을 실현해야 하는 존재이다. 인간은 우주적 조화와 질서의 중심에 있다. 인간은 만물을 사랑으로 다스려 완성시켜야 한다. 그런데 인간이 타락하여 심정을 상실하고 가정을 파괴하였으며 이기적이고 무책임하게 되었다. 그래서 이기적이고 무책임한 자세로 자연에 접근한 결과 자연을 파괴하고 환경을 오염시키게 된 것이다. 환경에 대한 통일원리적 비전은 전 피조세계를 상호 연관된 유기체로 보는 것이다. 자연은 하나님이 인간에게 주신 선물이다. 인류는 과학과 기술로 자연에 접근하여 사랑으로 돌보아야 한다. 인간은 자연에게 하나님의 사랑을 전하며 자연을 완성시켜야 한다. Unification Theology in the Age of Family Federation for World Peace and Unification(FFWPU) 1. Theology is a contemporary interpretation of truth and a contextual confession of faith 2. The "Unification Theology" in the age of FFWPU, therefore, should be different from what used to be the "Unification Theology" of the age of HSA-UWC. 3. The "Unification Theology" in the age of FFWPU cannot follow the paradigm of the past. 4. However, since Theology is basically what talks about God, the "Unification Theology" of the age of FFWPU should also be based on the same systematic pattern of the past. -- God and the created Universe, and the relationship between God and the Universe. 5. Based on the above systematic pattern of the past, the "Unification Theology" can be represented from a new paradigm of the thought of True Parents based on Father's recent speeches. 6. The "Unification Theology" in the age of FFWPU will follow the systematic pattern as follow'. 6.I True Parents God 6.2 True Parents Messiah 6.3 Completed Human Being as True Parents 6.4 Ideal World through the redemption of True Parents 7. The "Unification Theology" in the age of FFWPU in more detail will be as follow: 7.1 True Parents God 1. True Parents as revelation 7.2 True Parents Messiah 1. Rebirth by True Parents 7.3 Completed Human Being as a True Parents 1. Family Ethic centered on True Parents 2. Social Ethic centered on True Parents 7.4 Ideal World through the redemption of True Parents 1. The redemption history toward True Parents 2. The ideals of Interdependence, Mutual prosperity and Universally Shared Values centered on True Parents.
