  • The handwriting based person identification systems use their designer's perceived structural properties of handwriting as features. In this paper, we present a system that uses those structural properties as features that graphologists and expert handwriting analyzers use for determining the writer's personality traits and for making other assessments. The advantage of these features is that their definition is based on sound historical knowledge (i.e., the knowledge discovered by graphologists, psychiatrists, forensic experts, and experts of other domains in analyzing the relationships between handwritten stroke characteristics and the phenomena that imbeds individuality in stroke). Hence, each stroke characteristic reflects a personality trait. We have measured the effectiveness of these features on a subset of handwritten Devnagari and Latin script datasets from the Center for Pattern Analysis and Recognition (CPAR-2012), which were written by 100 people where each person wrote three samples of the Devnagari and Latin text that we have designed for our experiments. The experiment yielded 100% correct identification on the training set. However, we observed an 88% and 89% correct identification rate when we experimented with 200 training samples and 100 test samples on handwritten Devnagari and Latin text. By introducing the majority voting based rejection criteria, the identification accuracy increased to 97% on both script sets.

  • The Korea Institute of Energy Research(KIER) has been collecting horizontal global radiation data since May, 1982 for 16 different locations. KIER's new data is expected to be extensively used by designer and researchers of solar systems in lieu of unreliable old ones. Unfortunately, the quality of the data has not always been properly mentioned. Some of them were taken at temporary field stations where the primary goal of the measurement was quick estimation of local solar radiation. The purpose of this study is to systematically identify errors in such data set using clear-day analysis in an effort to rehabilitate error-ridden old data. Clear-day analysis successfully uncovered solar radiation data that had questionable quality. Even through the rehabilitation process not necessarily improves the quality of data for daily or monthly mean, it can be used to improve the quality of data for monthly means of several years and the processed data can be used in various applications of solar energy with more confidence. A average ETR value of 0.63 obtained in this study is in good agreement with previous results obtained by other researchers.

  • The purpose of this study is to examine the military look, which is one of the most popular fashion trends in the 1996 women's fashion. Military look is that imitates or reinterprets the Army uniform which is functionally useful. After World War 1 , military look appeared in the women's fashion which is functionable tailor suits style, ankle-length skirt, pants or boiler suits for work wear, overcoat against the cold, and there was an attempt to introduce a National Standard Dress. In the middle of World War II, there was a similiar circumstance in women's military fashion. There were functionable tailor suits, knee-length skirt, pants or siren suits for work wear. And the Utility Dress was nationally recommended. In addition, the regulations were introduced to control the materials and styles used for some clothes. In the 70s, as the resistance movement as counterculture began to wear Army look which was army-uniform or army caps with 'US ARMY' logo and badges, and became very popular among the youth. In the 90s, military look has got one of the fashionable fashion themes with revival of Neo- Hippie look. Not only street fashion but also high fashion designer selected the trend for '96A/W The characteristics of the military look are khaki colors or camouflage prints, epaulets, big outpockets with flap, golden buttons and army belt. As I examined, during the World War I and ll, women wore the military look because of shortage of goods and work or service, and it was recommended by government. Though the military look in 70s, began by the resistance movement, at least it became a popular fashion. Military look in 90s, does not have inner symbolic meaning or ideology but it only represents fashion trend and revival fashion.

  • In this thesis, I tried to compare and analyze the characteristics of the costume worn by leading figures of French movie 'Dangerous Liaison' and Korean movie 'The Scandal'. I compared the costumes they wear with the costumes of 18th century Fran[e and also tried to analyze how the costumes represent the psychological status of the persons in the movie. Since these two movies are based on the same original novel, the major figure's characters, socio-economic status and the situations they faced are similar but the physical background are very different, that is Fran[e and Korea. The analysis of the costume worn by similar characters in the two movies show differences due to the intention of tile producer's. The costumes used in Scandal shows much more use of varied colors to represent the characters of the major roles while Dangerous Liaison more faithfully follows the evidences of the costume used in the period in France. As seen from the result of this analysis, we can deduce that the costumes used in the movie not only have the simple role of clothes but also itforms the image of the figure in the movie representing the social and economic status of the person who wears them. Because of these demands, the designer should posses profound knowledge of history of the costumes of the period as well as the creativity to harmonize them with the atmosphere that the movie intend to appeal.

  • The purpose of the present study is to set up an efficient optimum design method for the large-scale reinforced concrete cylindrical shell structures like intake tower of reservoir and to establish a solid foundation for the automatic optimum structural design combined with finite element analysis. The major design variables are the dimensions and steel areas of each member of the structures. The construction cost which is composed of the concrete, steel, and form work costs, respectively, is taken as the objective function. The constraint equations for the design of intake-tower are derived on the basis of the working stress design method. The corresponding design guides including the standard specification for concrete structures have been also employed in deraving the constraint conditions. The present nonlinear optimization problem is solved by SUMT method. The reinforced concrete intake-tower is decomposed into three major substructures. The optimization is then conducted for both the whole structure and the substructures. The following conclusions can be drawn from the present study. 1. The basis of automatic optimum design of reinforced concrete cylindrical shell structures which is combined with finite element analysis was established. 2. The efficient optimization algorithms which can execute the automatic optimum desigh of reinforced concrete intake-tower based on the working stress design method were developed. 3. Since the objective function and design variables were converged to their optimum values within the first or second iteration, the optImization algorithms developed in this study seem to be efficient and stable. 4. The difference in construction cost between the optimum designs with the substructures and with the entire structure was found to be small and thus the optimum design with the substructures,rnay conveniently be used in practical design. 5. The major active constraints of each structural member were found to be the tensile stress insteel for salb, the minimum lonitudinal steel ratio constraints for tower body and the shearing stress in concrete, tensile stress in steel and maximum eccentricityconstraints for footing, respectively. 6. The computer program develope in the present study can be effectively used even by an unexperienced designer for the optimum design of reinforced concrete intake-tower.

  • China became the largest costume industry and export country since 1994. The fashion market in China has been changed from seller's market to buyer's market. During this period, brand has taken an important part. The fashion industry in China is developing on outlook, function, materials and categories. I want to do this brief research on the ten years of China Fashion Week to review the development of China Fashion Week, which is the symbol of China fashion industry. I hope it can be reference for being comprehended by Chinese and other foreign countries. In 1997, China Fashion Week was called Fashion Design exhibition. The title was modified to be China Fashion Week in 2000. In 2003. the title was developed to China Fashion Week (Spring/Summer Collection) and China Fashion Week (Autumn/Winter Collection). In the past ten years, there have been 300 fashion collections, with 600 fashion designers who joined in the competitions, and thousands of models, reporters and photographers, who took part in China Fashion Week. Recently 200 login fashion brands, 300 fashion designers, more than 500 reporters and 50 model management companies have made a relationship with China Fashion Week. The first moment of China Fashion Week- "famous designer project": paying attention to the relationship between the level of fashion designers and the style of brands. Quite a good deal of fashion design became more practical. The second moment of China Fashion Week- "improving Chinese fashion brands ": fashion show was not a kind of stage art but the business dealing for brand during that period. The situation of China Fashion Week now: Chinese Haute Couture is showed wonderfully during China Fashion Week. Fashion contest became the character of China Fashion Week. The contests were for adult fashion designers, new designers, models, and photographers. According to the development between different countries on fashion, the international communication of China Fashion Week became more and more popular and wide. Fashion designers from France, Italy, New York, Korea and Japan had fashion shows in China Fashion Week. The Chinese top fashion designers were showing their work during Paris, Milan and New York fashion shows.

  • Recently deformed or destroyed of soundproof wall by local winds and typhoon has increased. This research proposed the estimation method of the design wind load of soundproof wall using spatial information analysis based on 1:5,000 digital map and performed comparative analysis with actual application cases. According to the result of quantitative evaluation using GIS, the surface roughness in the downtown area packed with buildings was III and the surface roughness in the suburban district with a relatively small number of buildings was II and the surface roughness in the district packed with open areas and typical farmhouses was I. This shows that the wind load of the soundproof walls reflecting the actual surface conditions was estimated. If the quantitative GIS analysis presented in this study is applied to wind-resistant design of soundproof walls, it is supposed that this will be helpful in more rational wind-resistant design by remedying the existing problem in which the wind load varies depending on designer's subjectivity.

  • Recently, followed by rapid growth of robotics field, multi-linkage mechanism which can even pass by rough road is getting lots of attention. In this paper, I focused on Jansen mechanism. It's a kinematics object which is named after Dutch artist Theo jansen. Jansen mechanism embraces structure and mechanism which creates locomotion with the combination of the power and simple structure. Theo jansen suggests a 'Holy number'. It's an ideal ratio of leg components length. However, if there's desired gait locomotion, you have to adjust the ratio and the length. But even slight change of the length could cause a big change at the end-point. To solve this problem, I suggest a reverse engineering method to get a ratio of each links by nonlinear optimization with pre-set desired trajectory. First, we converted a movement of the joint of Jansen mechanism to vectors by kinematics analysis of multi-linkage structure. And we showed the trajectory at the end-point. After that, we set desired trajectory which we found most ideal. Then we got the length of the leg components which draws a trajectory as same as trajectory we set, using Multi-objective genetic algorithm toolbox in MATLAB. Result is verified by Edison designer and mSketch. And we analyzed if it could pass through the obstruction which is set dynamically.

  • For those unfamiliar with the shoe world, Pinet (1817-1897) was a contemporary of Worth, the great Parisian couturier. So I look at the glamour shoes and the world of haute couture, and indeed the development of the named designer. That is a concept we are all familiar with now. So it is not easy to comprehend the lack of names for the exquisite work before 1850. Straightway I have to say that the number of noted shoe designers is far fewer than famous dress designers, but I will introduce you to some of them, against the background of contemporary shoe fashions. Franc;ois Pinet was born in the provinces (probably Touraine) in 1817, two years after the end of the Napoleonic Wars. His father, an ex-soldier, settled to shoemaking, a comparatively clean and quiet trade. It had a tradition of literacy, interest in politics, and was known as the gentle craft, which attracted intelligent people. We should presume father would be helped by the family. It was usual for a child to begin by the age of 5-6, tying knots, sweeping up, running errands and gradually learning the job. His mother died 1827, and father 1830 when he was 13, and at the time when exports of French shoes were flooding world markets. He went to live with a master shoemaker, was not well treated, and three years later set out on the tour-de- France. He worked with masters in Tours and Nantes, where he was received as Compagnon Cordonnier Bottier du Devoir as Tourangeau-Ia rose dAmour (a name to prove most appropriate). He went on to Bordeaux, where at 19 he became president of the local branch. In 1841 he went to Paris, and in 1848, revolution year, as delegate for his corporation, he managed to persuade them not to go on strike. By now the shoemakers either ran or worked for huge warehouses, and boots had replaced shoes as the main fashion. In 1855 Pinet at the age of 38 set up his own factory, as the first machines (for sewing just the uppers) were appearing. In 1863 he moved to new ateliers and shop at Rue ParadisPoissoniere 44, employing 120 people on the premises and 700 outworkers. The English Womans Domestic Magazine in 1867 records changes in the boots: the soles are now wider, so that it is no longer necessary to walk on the uppers. There is interest in eastern Europe, the Polonaise boots with rosette of cord and tassels and Bottines Hongroises withtwo rows of buttons, much ornamented. It comments on short dresses, and recommends that the chaussure should correspond to the rest of the toilet. This could already be seen in Pinets boots: tassels and superb flower embroidery on the higher bootleg, which he showed in the Paris Exposition that year. I think his more slender and elegant Pinet heel was also patented then or 1868. I found little evidence for colour-matching: an English fashion plate of 1860 shows emerald green boots with a violetcoloured dress.
