Mobility of an indoor wheeled robot is affected by adhesion force that is related to various floor conditions. When the adhesion force between driving wheels and the floor decreases suddenly, the robot has slip state. First of all, this paper models adhesion characteristics and slip in wheeled robot. Secondly, the paper proposes estimation method of adhesion force coefficient(AFC) according to slip velocity. In order to overcome this slip problem, optimal slip velocity must be decided for stable movement of wheeled robot. The paper proposes an anti-slip control system based on an ordinary disturbance observer, that is, the re-adhesion control is achieved by reducing the driving torque enough to give maximum adhesion force coefficient. fuzzy logic controller(FLC) is petty useful with slip through that compare fuzzy with PI control for the controller performance. These procedure is implemented using a Pioneer 2-DXE parameter.

Paris has one of the world's oldest metropolitan railway systems and was also a pioneer when it introduced the RER in the 70s. With planning objectives comparable to the GTX, the RER aimed at serving outer suburbs while fully crossing the city center at higher speeds than the Metro. Maybe more relevant is the comparison between the planned Grand Paris Express and GTX projects, in terms of their planning ambitions and their development framework. This article will introduce the main planning ideas behind the Metro and the RER in Paris, and try to draw relevant comparisons with the GTX plan. It will also present the plans and financing framework for the Grand Paris Express and compare it with the BTO scheme contemplated for GTX, and draw some recommendations for successful implementation.

This study aims to compare the Malevich's 'non-objectivity' and Mies van der Rohe's 'almost nothing'. K. Malevich who, as a painter, was a pioneer of abstract art and an initiator of Suprematism, was sought an ultimate value of art to non objective world, namely non of consciousness or a world of a non-being, In the same way, 'Mies van der Rohe was also sought for architectural space of non objectivity, as non of objective, being introduced 'less is more' or 'almost nothing' to architectural space.

In this paper, we proposed a navigation algorithm of the mobile robot for obstacle avoidance using a circular path planning method. The proposed method makes circular paths in order to avoid obstacles in the front side of the mobile robot. An optimal path for approaching to the target is selected and the linear and angular speeds for stable moving of the mobile robot are controlled. Obstacles are detected by image processing which reduce image data obtained from a web camera. Performance of the proposed algorithm is shown by experiments with application to the Pioneer-2DX mobile robot.

This paper develops a novel automatic parking algorithm based on a fuzzy logic controller with the vehicle pose for the input and the steering rate for the output. It localizes the vehicle by using only external sensors - a vision sensor and ultrasonic sensors. Then it automatically learns an optimal fuzzy if-then rule set from the training data, using an evolutionary fuzzy system. Furthermore, it also finds the green zone for the ready-to-reverse position in which parking is possible just by reversing. It has been tested on a 4-wheeled Pioneer mobile robot which emulates the real vehicle.

This study aims to analyze the influence which Marie Antoinette, an unfortunate queen and fashion pioneer, had upon leading the creation of fashion in the eighteenth-century. In addition, this study attempts to expect some insights of fashion on the basis of analysis. Marie Antoinette created a new trend of fashion all the time through her hatred of restricting freedom, discontentment and caprice. She created the robes a l'anglaise, a la polonaise, a la levite, chemise a la reine, and so on. Also, Marie Antoinette created a giant hair style by hiring a hairdresser named Leonard. It can be believed that even though Marie Antoinette is open to censure owing to her frivolity, vanity and extravagance, she is recognized a creator of womanish, beautiful, delicate and graceful dress and ornaments.

The goal of this study is to analyze the influence of the costume culture of South Korean movies and television series on the development of fashion industry. South Korean movies and television series make full use of the influence of costume culture to advocate Korea's national spirit and character as well as the confidence and vigor of the young generation. They contribute to establishing South Korea as a country with a graceful, modern appearance and great cultural heritage. The presentation and promotion of its costume culture in movie and television series stimulates its cultural competence and advances its cultural creative industry. The spread of Korean costume culture has become the pioneer and foreshadowing of clothing industries and greatly underpins its advancement overseas. In concert, the development of clothing industry helps the spread of Korean costume culture.

RFID has fundamental influences on today's business management. This research seeks to formulate the opportunities and challenges, the strengths and weaknesses and the perceived benefits of RFID implementation in three industries: manufacturing, medical-service, and distribution. Ten companies of successful RFID deployment in Korea are presented. Field interview and panel discussion were used to explore the research purpose. The core challenges include RFID readability issues, lack of best practices, increasing prime cost, visible ROI, implementation cost, and employee's resistance. The strengths include IT infrastructure, system integration competency, RFID business model creation ability, executive's support. There is little weakness in Korea companies, there are many perceived benefits in three industries. The most distinctive finding is that the visible ROI was found out in the manufacturing industry, not in the distribution industry. The opportunities and challenges, the strengths and weaknesses and the perceived benefits are some different in three industries, which provide valuable guidance for Korean companies in seeking the RFID opportunities. This case study represents a pioneer research of RFID adoption in Korea.

This paper presents collision avoidance for mobile robots equipped with synchro-drive using curvature trajectory by the obstacle type. he new real-time obstacle avoidance method presents how to create a curvature trajectory in which dynamics of a mobile robot is considered we controlled translation and rotational velocity of the mobile robot. Using these two speeds with curvature trajectory, the mobile robot navigates to target point without collision. We consider that the robot going to curvature trajectory by obstacle size towards a goal location. The collision avoidance has been implemented and tested using pioneer2-dxe mobile robot.

avant garde poet Yi Sang wrote his poetry with architectural and artistic inspirations. his artistic creativity was exploded by typographic expression. he lirerated the !iterated word into visible language also. he played with his-own-created-signs. fighted against the reality, traditions and cliches. his typographic characteristic poetry is an evidence for the lengthening the history of korean modern typography as a pioneer. because his experimental works is the great evident. so we evaluated the worth of it.
