In this paper, chord progress pattern of popular music is analyzed, and based on this optimal chord pattern, bit matrix of melody information is used for the input vector of neural network. Experimental result showed that possibility of computer composition based on neural network is verified. With regard to some given melody, by making use of proposed method, it is also possible to reconstruct the various melody.

A new direction of arrival estimation method using effects of model errors and sensitivity analysis is proposed. Since a desired signal is obtained after interference rejection through correction effects of model error, the effect of channel interference on the estimation is significantly reduced. Through simulation, we show that the proposed method offers significantly improved estimation resolution and accuracy relative to existing method.

As various media have developed in modern society, frequency of use of interactive media has increased which makes interactive function that uses and handles projection mapping and LED screen in set design of broadcasting, concert, play, musical and EDM(Electronic dance music) in real time possible. Development of various media led today's viewers to have higher cultural desire and the need of various interactive performance contents to receive more attention.[1]. This thesis implemented real time VJing that responds to user's motion based on existing H/W by utilizing real time interactive elements.

Harmony search (HS) is a relatively recently developed meta-heuristic optimization method imitating the music improvisation process where musicians improvise their instruments' pitches searching for a perfect state of harmony. In the conventional HS algorithm, it is necessary to determine the maximum number of iterations with some algorithm parameters. However, there is no criterion for determining the number of iterations, which is a very difficult problem. To solve this problem, a new method is proposed to perform the algorithm without setting the maximum number of iterations in this paper. The new method allows the algorithm to be performed until the desired tuning is achieved. To do this, a new variable bandwidth is introduced. In addition, the types and probability of harmonies composed of variables is analyzed to help to decide the value of HMCR. The performance of the proposed method is investigated and compared with classical HS. The experiments conducted show that the new method generally outperformed conventional HS when applied to seven benchmark problems.

The purpose of this paper is to make sure of identity as a paradigm of new fsahion to introduce the concept of Sumulacres by J. Baudrillard, For converting to new aesthetic value. To do this, we started observing the general concept of Simulacres, and examined Cyberpunk within thinking of Simulacres and Cyberpunk fashion at virtual space, and then divided aesthetic consciousness appeared at Cyberpunk fashion centering on the concept of Simulacres into inwards sense and outwards sense. Cyberpunk is understood to be one of tendency in the cyber cultures controlled by computer and electronic technology. It is not yet defined clearly and therefore ambiguous and still being elaborated. However, the form started changing our sense sinking into overall cultures in the World, including even movie, literature, music and fashion, and giving complex, deep cultural and artistic possibilities. Also, as a subculture, Cyberpunk is building its own cultural territory in cyber space and is experiencing more real Simulacres than that of it in the ordinary life.

In this paper, in the middle of progressing popular music chord, a method of inserting melody is addressed, which utilized by analyzing chord progress pattern. Firstly, a method for transforming melody into bit pattern which is to be used for neural network input is described. In order to insert the melody, composition pattern is learned from back propagation neural network, and based on these data new melody is to be generated. Experimental results verified the possibility of neural network based computer composition.

"Science" journal is one of the world's top academic journals. Many researchers are trying to publish their work in Science, and only a few selected novel papers are accepted. However, we think that this kind of process cannot continue forever. In this paper, we show that there is a limit to the number of Science papers that can be written. Therefore, the day will come when Science cannot publish new papers anymore. Using a similar method, we estimate the maximum limit on the number of pop songs that can be composed. By extending our discussion to all kinds of digital contents, we derive a mathematical expression for the maximum number of digital contents of a certain type that can be created. These results imply that someday man will not be able to produce new papers or new digital contents anymore. This conclusion raises deep philosophical questions.
