The main objective of this research was to understand the characteristics of pleats design through the analysis of modern female fashion as they appear in the 'Collections' from '09 A/W to '12 S/S. Data collection of 1027 was done through the review of 'pr$\hat{e}$t-$\grave{a}$-porter Collections' of three cities; Milan, New York, Paris. Along with the qualitative interpretation of pleats design, statistical analysis of frequency and ${\chi}^2$-test were completed for data analysis. The main findings were as follows; 1. The five types of pleats design were founded in the order of accordion, knife, box, inverted, and sunburst pleats. The frequency and ratio of pleats design occurency showed significant difference between collections. 2. There were significant difference between the types of pleats and their line characteristics of thickness, continuity, length, direction. = Thin fabrics with delicate fine folds were mainly appeared in accordion and sunburst pleats. On the other hand, midium thickness fabrics were used for knife, box & inverted pleats, however, the different images were projected according to the width and the number of folds, characteristics of fabrics and textures. = In all the type of pleats but sunburst, continuity line was appeared the most. The discontinuous lines were appeared the most in the layered types and, sometimes, at some construction lines to add some decorative details or design variations. = The long line were the most frequently appeared in long one-pieces or long skirts of knife, accordion, sunburst pleats. While, the shorter lines showed the most frequently in box and inverted pleats, which mainly used for skirts or the lower part of one-piece. = For the line directions, the vertical lines were the most frequently appeared, and followed by mixed and diagonal line. In mixed or diagonal lines, same type of pleat was repeated in one design. For diagonal lines, one direction was mainly used, however, the symmetrical arrangements or repeated diagonal pleats in various directions also used. In mixed lines, the type of one or two diagonal and one vertical line was the most frequently appeared.

A method for approximating the failure surfaces for columns in compression and biaxial bending was proposed by using the moments along the line of a diagonal of the section. This method showed the better approximations for the failure surfaces of columns than the method of ACI. To calculate the moments along the line of a diagonal of the section, an approximate method which is not influenced by the number of steel s and the location of inner steels was proposed This method gave satisfactory approximations for practical sections of columns.

An improvement of tracking capacity to find a position of the Iris images is presented in this paper. The propose algorithm is used the Four Points Diagonal Positioning algorithm that the image is positioned with arbitrary 4 points on the edge of iris and the selective 4 points are drawn by a diagonal line on the cross. The experiment result shows that the algorithm is efficient to track on the eyelid.

The microstructures of top seed mult processde $\textrm{YBa}_2\textrm{Cu}_3\textrm{O}_7$.$\delta$ single crystal were studied. Although shape of the seed was not faceted. the growth shape of Y123 single crystal was faceted. It was observed that Y211 phases were trapped in specific spaces of the faceted region. From the microstructural investigation. it was suggested that the segregation of Y211 is due to the difference of growth rates in crystal direction. When a single crystal was grown by the single seed with stepped multi surfaces. a microstrue was grown from multi-seed. The microstructure show the possibility of multi-seed growth. Corn kernel like structure without Y211 phase was observed and seemed to be formed by the diffusion reaction between Y211 phase in crystal and liquid wetted on the crystal. the diagonal line on Y123 crystal was observed that it was formed by the corn kernel like structure.

본 논문에서는 자동차 번호판을 검출하는 새로운 방법을 제시한다. 자동차 번호판은 사각형 모양이므로 우리의 방법은 기본적으로 입력 영상에서 사각형을 추출하는 방법이 된다. 번호판을 검출하기 위해, 먼저 입력영상의 콘트라스트를 향상시키고, 그 후 LSD(Line segment detector) 기법을 사용하여 영상내의 선을 검출하고, 이 선 정보로 부터 사각형들을 추출 한다. 이 사각형들은 번호판 후보들이 되고, 이로부터 번호판이 검출된다. 이중에서 본 연구가 제안하는 부분은 사각형 추출방법으로서, 이 방법은 3단계로 구성된다: (1) 먼저, LSD에 의해 얻어진 선으로부터 꼭짓점들을 추출한다; (2) 구해진 꼭짓점들을 사용하여 사각형의 대각선을 검출한다; (3) 그 후, 대각선 정보를 이용하여 사각형을 추출해 낸다. 최종적으로 번호판 특성과 사각형 내부 정보를 이용하여 이 사각형들로부터 번호판이 선택된다. 100장의 자동차 영상을 촬영하여 실험한 결과 94%의 검출율을 달성하였다.

This paper decides provision of brightness by average value of horizontal pixel, vertical pixel association. Give weight at association value calculation to improve diagonal line characteristics, and applied method to add average of vertical pixel and average of diagonal line pixel at interpolation. Therefore it improves PSNR, and it proposed algorithm that improve horizontal outline and vortical outline characteristics in big area of luminance contrast. It changed scanning line of serial scan based on proposed algorithm and designed variable image system for efficient data transmission through PCI interface circuit.

In this study, we prepose the dynamic gait in consideration of emerge efficiency. The proposed dynamic gait is applied to the quadruped walking robot and experiments are performed for real robot. We proposed the dynamic gait is diagonal gait which is modified the trot gait in consideration of energy efficiency. The proposed gait is composed of two steps. In one step, the robot walks in the trot gait. In the other step, the robot walks with making the center of gravity lie on the two legs supporting line. Realization of the diagonal intermittent trot gait is performed by open loop contal and motion planning of the proposed gait. The validity of the purposed gait is confirmed by our experiment.

In this paper, we propose the self-tuning of PID controller using diagonal recurrent neural networks. The characteristic of the proposed structure is on-line adaptive learning scheme in spite of variations of feedback, signals. Control performance is compared with that of neural network based PID controller which was proposed by Iwasa. Computer simulation results show that the proposed controller is effective in controlling of unknown nonlinear plants.

본 논문에서는 직선을 판별하는 판별방법과 또한 직선으로 판정되는 경우 직선의 8가지 방향에 대한 판정을 위하여 좌표정보와 삼각함수 성질을 이용하여 직선 8반향 알고리즘을 제안하였다. 본 실험은 각 동작 별로 100회씩 총 800회를 실험 하였으며, 본 논문에서 제안한 알고리즘을 통한 정확도는 왼쪽 위로의 대각선 방향이 92%로 가장 높았으며 왼쪽 방향, 오른쪽 위로의 대각선 방향과 오른쪽 아래로의 대각선 방향이 모두 82%로 가장 낮은 인식률을 나타내었다. 이 방법은 기존 방법과는 다르게 학습과정 없이 이미지 처리를 통해 얻은 좌표 정보만으로 손 제스처 인식이 가능하다는 것을 보여준다.
