A large number of people download music files easily from Web sites. But rare music sites provide personalized services. So, we suggest a method for personalized services. We extract the properties of music from music's sound wave. We use STFT (shortest time fourier form) to analyze music's property. And we infer users' preferences from users' music list.(More)
In fuzzy modeling, it is relatively easy to manually define rough fuzzy rules for a target system by intuition. It is, however, time-consuming and difficult to fine-tune them to improve their behavior. This paper describes a tuning method for fuzzy models which is applicable regardless of the form of fuzzy rules and the used defuzzification method. For this(More)
In this paper, the concepts of structured and nonstructured concurrency are introduced to classify concurrent systems, and a hierarchical partition method is used to handle the complexity of nonstructured concurrent systems. A concurrent system with structured and nonstructured concurrency is modeled by a precedence graph. The language of the precedence(More)
P. M. Fins, " The information capacity of the human motor system in controlling the amplitude of movement, " Abstract-In this paper, the concept of hypergraph is extended to the fuzzy hypergraph. In the fuzzy hypergraph, the concepts of a-cut hypergraph, strength of edge and dual fuzzy hypergraph are developed. It is shown that the fuzzy hypergraph and(More)
