This study is an analyze for Casa del Fascio, of Giuseppe Terragni, an important architect of fascism period of Italy. Based on the spot reinvestigation of first copies and unpublished data in a archive for a month of 2002. August, Terragni, Como, to compromise with the limit of studies up to the present. General's from early scheme to final constructed scheme, finally offered standard way to understand Terragni's scheme. Result of analyze are to two conclusions. 1) It has direct bearings between physical environment of site which was to build from original scheme and final decided external form. Especially there is direct relation between facade and composition of Duomo Cathedral, in the center of Como. 2) Although the image for scheme by architect represented as a physical form which was impossible to analyze the data as development sequence from archive, it influences on the first image, which had changed many times, exists as important element to final constructed scheme.

'Otherness' is a major philosophical concept in modern Western thought. It has been a force through which the concept of a subject's rights emerged. This paper focuses on Emmanuel Levinas' discussion of 'otherness.' Levinas emphasizes our ethical responsibility for others, which is meaningful in that it can be applied as a paradigm of communication for use in modern society. In the context of modern times and multicultural societies, it is important to recognize the diversity of others and to promote coexistence. Coexistence at this time should be 'unifying' rather than subject-centered. This paper attempts to understand this narrative. An epic is a cognitive process that constitutes the fundamental desires and experiences of humans. Humans try to project and understand themselves through narratives. The possibility of coexistence with others can be examined by analyzing otherness as found within those narratives. Therefore, this paper suggests the possibility and direction of coexistence by analyzing the storytelling that establishes relationships by shaping characters in Guillermo del Toro's film, Shape of Water.

Metal emulsions have been studied for several decades as a method of increasing the efficiency of the steelmaking process. This study was performed using a water model, observable at room temperature, to compensate for the disadvantages of the high-temperature experiment, the results of which are difficult to observe visually. As a substitute for metal-in-slag emulsions, experiments were conducted by dropping distilled water into silicone oil and comparing the results with the results of a calculation by momentum balance equations. The descending velocity of the water droplet decreased as the diameter of the droplet and viscosity of the fluid (silicon oil) increased. To simulate the descending velocity of a water droplet in silicon oil under stirring conditions, the flow rate of the fluid (silicon oil) was measured by particle image velocimetry (PIV) methods. The calculation of the descending velocity of the water droplet was in good agreement with the measured values, with and without stirring a viscous silicone oil.

Water modeling experiments and computer simulation for the predictions of defects of die castings are very important to produce high quality castings with less cost. The relation between the variable air vent system and the characteristics of the fluid flow in the die cavity is studied by using water modeling tests, which give ideas on reasonable designing of die cavity, vent arrangement and gating system. In order to test the water modeling, injection is done by using water containing NaCl. Flow behaviors in cavities are visualized by high speed camera and video tape recorder, and local filling time is measured with electrode sensors. Special attention is paid to the configuration of die cavity. Simulated results by computer are examined and compared with the results of water modeling experiments. There are close correlations between the simulated results and water modeling ones.

In this paper the word recognition using sub-model based Hidden Markov Model was studied. Phoneme models were composed of 61 phonemes in therms of Korean language pronunciation characteristic. Using this, word model was maded by serial concatenation. But, in case of this phoneme concatenation, the second and the third phoneme of syllable are overlapped in distribution at the same time. So considering this, the method that combines the second and the third phoneme to one model was proposed. And to prevent the increase in number of model, similar phonemes were combined to one, and finially, 57 models were created. In experiment proper model structure of sub-model was searched for, and recognition results were compared. So similar recognition results were maded, and overall recognition rates were increased in case of using parameter tying method.

최근 프로그래밍이 가능한 그래픽스 프로세서(GPU)의 등장은 렌더링 속도의 향상은 물론 기존의 GPU가 할 수 없었던 다양한 그래픽스 계산을 효과적으로 수행할 수 있도록 해주고 있다. 이로 인하여 기존에 CPU 상에서 수행해야만 했던 그래픽스 계산들의 일부를 GPU 상에서 수행하도록 해주는 기법들에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 선형식에 기반을 둔 여러 응용 문제들을 GPU 상에서 효율적으로 구현할 수 있도록 도와주는 쉐이더 코드 최적화 기법을 제안한다. 이 기법은 SIMD 형태의 병렬 처리 능력을 가진 버텍스 쉐이더의 명령어에 맞게 고안되었다. 본 기법의 활용 가능성을 보이기 위하여 미분 방정식을 풀기 위한 4차 런지-쿠타 방법, 선형방정식을 풀기 위한 가우스-자이델 방법, 자연스러운 유체 모델링을 위한 파동 방정식 등의 문제에 적용하여 보았다. 본 논문에서 제안한 최적화 기법은 버텍스 쉐이더 용 컴파일러 구현에 쓰일 수 있으며, 향후 프로그래밍이 가능한 GPU 상에서의 실시간 그래픽스 소프트웨어 개발에 유용하게 사용될 수 있을 것이다.

A vehicle cruise control algorithm using an Interacting Multiple Model (IMM)-based Multi-Target Tracking (MTT) method has been presented in this paper. The vehicle cruise control algorithm consists of three parts; track estimator using IMM-Probabilistic Data Association Filter (PDAF), a primary target vehicle determination algorithm and a single-target adaptive cruise control algorithm. Three motion models; uniform motion, lane-change motion and acceleration motion, have been adopted to distinguish large lateral motions from longitudinal motions. The models have been validated using simulated and experimental data. The improvement in the state estimation performance when using three models is verified in target tracking simulations. The performance and safety benefits of a multi-model-based MTT-ACC system is investigated via simulations using real driving radar sensor data. These simulations show system response that is more realistic and reflective of actual human driving behavior.

In this study, an analysis technique using simple beam model for predicting structure crashworthiness of the passenger car side impacted with an angle by another passenger car was investigated. The simple model was composed of major beam-like side structure which carry almost all side impact load. A procedure of component collapse test, calculation of load carrying capability and dynamic simulation was carryed out sequentially. Transient dynamic algorithms and a computer program to simulate deformations and motions of the impacted car was developed. The developed procedure was applied to a 3 door passenger car side impacted with an angle of 75 degree and the analysis results show good agreements with the actual test results.

A Bi-2223 tape has been developed for power applications such as power cables or transformers working at liquid nitrogen temperature. For such applications it is required to understand fault current characteristics of the Bi-2223 tape. In this paper, we report fault current characteristics using two types of samples, straight sample and pancake coil sample. It was found that the fault current characteristics of the Bi-2223 tape are depend on electrical insulations and fault durations strongly. Also it was shown that the fault current characteristics in the insulated straight sample are similar to those in the pancake sample with a conductor insulation. Finally, it was shown that the pancake sample with a layer insulation has better characteristics than that with a conductor insulation for fault currents.

The poblem of active oise control has been analysed using a adaptive signal processing technique. In this methods, the adaptive signal processor or model predicts the primary sound wave travelling along the acoustic plant and generates the secondary source 180° out of phase which attempts to attempts to attenuate the undesired noise by destructive interference. In the solutions presented here, acoustic propagation delay is considered as a part of the model which used the FIR filter. The effects of error path and auxiliary path transfer functioin are anayzed and a new on=-line technique for error path modeling, adaptive delayed inverse modeling is presented. In this study, using these new concepts, our system can more reduce the noise level in duct to 5dB-15dB than only using LMS algorithm system.
