Optimally Overlapped Ultrasonic Sensor Ring Design for Minimal Positional Uncertainty in Obstacle Detection

김성복,김현빈 제어·로봇·시스템학회 2010 International Journal of Control, Automation, and Vol.8 No.6

This paper presents the optimal overlapping arrangement of a circular array of ultrasonic sensors for minimal positional uncertainty in obstacle detection. First, it is shown that beam overlap among three adjacent ultrasonic sensors leads to significant reduction of positional uncertainty. Second, the positional uncertainty of an overlapped ultrasonic sensor ring is compared to a single ultrasonic sensor in terms of a collision-free region with obstacles. Third, the optimal design index for an overlapped ultrasonic sensor ring is defined as the area closest between the non-overlapped and overlapped sensing sub-zones. Fourth, using commercial low directivity ultrasonic sensors, an optimally over-lapped ultrasonic sensor ring is given along with its prototype installed on top of a mobile robot. Finally, experimental results are given to demonstrate the validity and performance of our overlapped ul-trasonic sensor ring prototype.

金聲福 이화여자대학교 한국문화연구원 1982 韓國文化硏究院 論叢 Vol.41 No.-

In order to fully understand the musical activities of Franz Liszt during his younger years, the author has given thought to the piano, a musical instrument which many people of that time were eager to own. The piano was the best instrument to satisfy the musical desire that arose in the English societies as a result of the Industrial Revolution. Accordingly, a pursuit to know through what process the piano developed and how widely the instruments were supplied to the public was made. Because of the increasing supply of pianos, the demand for piano compositions was great. Therefore, many composers wrote to meet the demand. Out of this came professional performers and this led to produce the musician executive: musicians themselves participated in managing the musical activities. Generally, these musicians were formerly related to the royal or titled families. Liszt, a brilliant virtuoso pianist of the time, aimed at creating more popular performances to stir public interest. He made transcriptions of the popular songs of the days to use in his concerts. These transcriptions, however, gradually disappeared in the ebb tide of the times. Liszt produced many transcriptions with complicated figurations to display his superhuman technique and to seize the public audience. There transcriptions help us recognize even today after such a long lapse to time, how brilliant Liszts techniques and abilities were. Lastly, there were numerous works created with devotion, respect and affection for the original composers. Nowadays, these works are adopted frequently in the repertoire of excellent pianists with respect and affection toward Liszt. The activities if Liszt during his younger years must become the manure for those of this mature years.

General department students say that their school environment is unsatisfactory for their health life while social sports department students think it just normal. 2) Social sports department students think that they are enjoying good health while their counterparts in other departments answer that their health is just normal. Male social sports students think that excessive smoking,drinking,unbalanced foods and irregular eating habit can be the major causes of poor health. 3) Most students respond that they are usually a little tired. Social sports department students find its cause in the lack of sleep while other department students cite the lack of exercise. 4) Most students think that enough rest and exercise are the most important factors to maintain their good health but they also say that their eating habit is not good. 5) Male social sports students answer that they have good appetite while other department students respond that theirs is just so and so. Most of them,regardless of their departments,say that they usually eat snacks once or twice a day. 6) Most students say that they usually sleep 6 or 7 hours a day and they don’t think it enough. ^* Consciousness about sports 1) Most students respond that sports activities are a must and they cite the objective of their engaging in sports activities is,first of all,to get rid of stress. Male students emphasize the importance of their physical training while female students hate obesity very much. 2) Male students in general departments favor billiards while social sports department students like tennis and basket-ball. Female students in other general departments want to do bowling while female students in sports department favor aerobics. General students want to do fencing in the future while male sports department students want to do hang gliding but female ones want to do aerobics. 3) General students use school grounds or vacant space near their homes as their exercise places but social sports use commercial sports centers,school grounds and public sports facilities,usually along with their friends. 4) Other department students usually do exercise once or twice a week,spending about 30 minutes or one hour each time but social sports department students spend more than an hour each time. 5) Most students think that they need a leader in their sports activities. General department students think that their biggest trouble is their insuffient pocket money while social sports department students cite insufficient sports facilities and suitable places for doing exercises. 6) Most students think that the facilities they are using now are just so and so. They also respond that more sports parks,comprehensive health towns,indoor sports centers and swimming pools should be built or expanded.

글룩의 오페라 개혁 이전의 프랑스, 독일, 영국 오페라의 사적고찰(17∼18세기)

Opera which wart generated at Firenze, Italy, at the clone of 16c was spread across the whole of Europe in all directions, and it went on extending throngh France, Germany, and England. By the way, among these three countries that imported Italian opera, the most aucesaful country was France. France which imported opera at the middle of 17c made good use of their Ballot, so they bad come to make Italian opera that is the national opera. This opera has the originality and individuality at the beginning of 18c in accordance with a sort of French temper. R. Cambert, J. B. Lully. A. Campra. J. P. Rameau and etc can be said to be the representative composers of French opera of 17∼18c. R. Cambert was the founder of French opera, and he had been holding the right to a monopoly of French opera performances until J.B, Lnlly's appearance. J. B. Lully con be considered as the man who made opera take ell a French style. He came from Firenze, Italy, and was naturalized in France. He left many works and achievements under Louis's XIV love and care cooperating with the literary man Molie´re and the poet P. Quinault. A. Campra was famous as an early opera composer of France after J. B Lully, and an another conspicuous man was J. P. Rameau. He was the composer who succeeded French opera after J. B Lully rind left the largest achievements as a composer. He left immortal traces as opera composer and musical theorist, also. At the time of Bouffon's Quarrel, he was the man who continued to support the value of French music and opera by safeguarding French opera and was one of the moat famous compasers at the time of the late Baroque music. On the one hand, there was Singspiel which had been called a musical in Germany, but it could not be regarded as an opera. Though Germany imported opera earlier from Italy than France and England, because they didn't use the opera style originally, the development. of German opera had fellen behind. Italian opera had been extended across the whole of Germany from about 1618, Germany played a role as a branch office of Italian opera, so German opera composers could'nt succeed in life unless they composed opera to Italian styles. But, only the Diatrict of Hamburg had gotten out of the influences of Italian opera, and the national music sect of Germany was generated under free sovereign power of that district from 1678, so we came to call this the Hamburg music sect. But about 60 years later even Hamburg was with drawn because of the power of Itaiian opera from about 1738, so German opera had. gradually disappeared. After that, they had to wait far Mozart's appearance in order to get their own real German opera. H. Schiitz who is known ns the founder of German opera can be regarded as the representative opera composer of Germany and we can suppose that R. Keiser, J. Matteson and etc fire the representatives of Hamburg music sect. At the clave of loc in English opera, though there was a light musical combined with dance and play, because this had use to be performed at oxy the Royal-Court by a part of the aristocracy, it was not thought of opera. At the beginning of 17c this Came to appeal on open stage from about 1635, and had been called "Masque". A myth or an allegorical character was its contents. Because opera was developed γacidly In 1655 after the restoration of Imperial regime of Charles II, opera had been imported from France. It can be said that the representative composers of English opera are P. Humphrey, M. Lock. J. Blow, and H. Purcell. Among them, H. Purcell was the cost conspicuous composer who left immense achievements on English music and the history of opera. There is "Dido and Apneas" as his masterpiece that is opera on a small scale style. This skillfully expressed. a transparent color sense of rich Ballet music and dramatic power of expression. He is the first and last man who was thought to composer of a full-length English opera, at came time in spite of his short life of 36 years, he left many achievements in musical history.
