  • Quadrotor UAV (Unmanned Aerial Vehicle) is a flying robotic platform which has drawn lots of attention in the recent years. The attraction comes from the fact that it is able to perform agile VTOL (Vertical Take-Off Landing) and hovering functions. In addition, the efficient modular structure composed of four electric rotors makes its design easier compared to other single-rotor type helicopters. In many cases, a quadrotor often utilizes vision systems in order to obtain altitude control and navigation solution in hostile environments where GPS receivers are not working or deniable. For carrying out their successful missions, it is essential for flight control systems to have fast and stable control responses of heading angle outputs. This paper presents a Fuzzy Logic based lateral PI controller to stabilize and control the quadrotor vehicle equipped with vision systems. The advantage of using the fuzzy based PI controller lies in the fact that it could acquire a desired output response of a heading angle even in presence of disturbances and uncertainties. The performance comparison of the newly proposed Fuzzy-PI controller and the conventional PI controller was carried out with various simulation results.

  • Picasso had deep concern at the designs of theatre costumes as well as art. The art of Picasso influenced deeply to the fashion designs in those days. In these study, to analyze the creative theatre costumes of Parade affected by Picasso's cubism, we investigate the documentary records, photos, and sketches of Picasso. The design of theatre costumes in Parade was able to be divided by two categories, general theatre costumes and experimental theatre costumes. The first characteristic of general theatre costumes is that the designs of theatre costumes in Parade were influence by the early stages of Picasso's art. The costumes of the Chinese Conjurer influenced by the Red Era of Plcasso's art and those of the Little American Girl and the Acrobats influenced by the Blue Era of Picasso art may belong to the category of general theatre costumes. The second characteristic of general theatre costumes is the fact that the images of heavenly bodies were used in the costume of the Chinese Conjure and the Acrobats. The characteristic of experimental theatre costumes is the fact that the cubism is introduced to the designs of theatre costumes in Parade. The experimental theatre costumes were presented in the costumes of the Three Managers which were newly created under the influence of Picasso's cubism.

  • This study is to focus on an innate creative 'spirituality' of Weimar Bauhaus' pedagogical thoughts and their backgrounds. In particular, this notes three elements of Universal mysticism, Orientalism in early Bauhaus including Expressionism, and Froebelian Education as the more practical among the romantic legacies as a source of modernism. Arguably, through these researches, just as the expressionists represent the crystallization of glass as the spirit, the important that should be noticed is explained as the fact that a panentheistic Idea of matter and spirit as a whole had been spreading to be recognized consciously or unconsciously; in other words, this awakening as dualistic monism might be one of the greatest peculiarities of modernity, and, as the fact that the universal thought and principle of 'panentheism' emphasizing a 'divine' artistic volition which is immanent in the individual is implanted first of all fundamentally by Froebelian educational influences.

  • 원숭이와 바나나 문제는 인공지능과 관련된 여러 문헌에서 문제 해결(problem solving) 과정을 설명하는 예제로 자주 등장한다. 그러나 이 문제에 대한 전통적인 접근 방식은 추론을 수행함에 있어 절차적(procedural) 관점의 도입을 필요로 하며, 이는 복잡한 문제 해결에 제약 조건으로 작용한다. 그러나 대규모 병렬 처리가 가능한 DNA 컴퓨팅 기법을 이용하면서, AI 본연의 의미를 퇴색시키지 않고서도 이 문제를 효과적으로 해결할 수 있다. 본 논문에서는 DNA 분자를 사용해서 원숭이와 바나나 문제를 표현하는 방법을 설계한 후, 컴퓨터 시뮬레이션을 통해 다양한 해들(solutions)이 생성됨을 확인하였다. 전통적인 방법으로 구현된 Prolog 프로그램이 단 하나의 최적해밖에 제공해 주지 못한다는 사실과 비교해 볼 때, 이것은 확실히 흥미로운 결과이다.

  • The purpose of this study was to analyze the planning guideline of individual space size for public library. The 26 cases were selected from the data of outstanding libraries built after the year 2000. The paper focused on the comparison between the data from analysis and the guideline from manual book of public library. The result of this study was as followed ; The first, reference reading rooms were open-plan rather than segmented. The second, the percentages of reference reading spaces from the data were lower than the guidelines. It proved the fact that the role of public library expanded to cultural community space. The third, children's space retained sufficient numbers of book collections. It represented that people realized the importance of children's library in terms of cultural education. The fourth, the percentage of space size of cultural area showed high amount of numbers. It proved the fact that the public library as community center was required various cultural programs. The fifth, the percentages of preservation library were lower than the guideline in case of the big libraries, while the small libraries were higher. The book collections of detached annex libraries should be linked with the central libraries.

  • In this paper, optimized model was designed for the starting characteristic of the Single-Phase Line-Start Permanent Magnet Synchronous Motor by using the Design of Experiment. A field pole angle, thickness and distance from center axis of permanent magnet were selected as design factor. We executed the transient state characteristic analysis of 8 test models. The transient state characteristic analysis was executed by using the 2 dimensional Finite Element Method and the Time Difference Method. We checked the fact that the selected design factor affected starting characteristic of the Line-Start Permanent Magnet Synchronous Motor. Depend on this result we found the optimized design point by using the response optimization.

  • A bubble diagram is understood as a graphic medium which bridges program and plan in architectural design process. The role of a bubble diagram is either to generate or to explain a plan in relation to its program. Despite the explicit role of a bubble diagram in architectural design process, what a bubble diagram indicates exactly is very ambiguous. Here I attempt to reveal the nature of the bubble diagram more sharply. My main argument is that the ambiguity of a bubble diagram results from the fact that it is used to range two different types of representational formats. Reviewing the theories of shape recognition and shape representations in vision science, I will also argue that the procedural description of architectural design process should be criticized and that the focus of design method research has to be shifted into the representational format of form description in architectural design process.
