Grid computing is a service for sharing computer resources and data storage capacity over the internet. As resource requirements of recent applications increased greatly, grid systems have gained importance in the last decade. Resource discovery is the essential job in Grid computing which provides searching and identifying necessary resources for given processes. There are various Resource Dis...

This paper presents an automatic harmonization method that, for a given melody (sequence of musical notes), generates a sequence of chord symbols in the style of existing data. A typical way is to use hidden Markov models (HMMs) that represent chord transitions on a regular grid (e.g., bar or beat grid). This approach, however, cannot explicitly describe the rhythms, harmonic functions (e.g., t...

This extended abstract describes a submission to the Music Information Retrieval Evaluation eXchange 2010 (MIREX 2010) in the Audio Chord Estimation and Audio Key Detection tasks. We propose a new model to recognize musical keys and chords simultaneously from musical acoustic signals including key modulations. Chords and keys are closely related notions of music involving harmony. Since occurre...

Creating distinctive harmonizations in an identifiable style may be one of the most difficult tasks for amateur song writers, a novel and acceptable melody being relatively easier to produce; and this difficulty may result in the abandonment of otherwise worthwhile projects. To model and assist in this creative process, we propose a hybrid system for generating style-specific accompaniment, whi...

This paper presents a formal model of Schoenberg’s guidelines for convincing chord root progressions. This model has been implemented as part of a system that models a considerable part of Schoenberg’s Theory of Harmony. This system implements Schoenberg’s theory in a modular way: besides generating four-voice homophonic chord progressions, it can also be used for creating other textures that d...

congenital undescending testis is a common anomaly of testis, but we had a rare case of ectopic testis. a 15-month-old infant was operated emergently because of left incarcerate inguinal hernia. intraoperative exploration of hernial sac revealed two ectopic testes with one spermatic cord proximally but in the middle divided to two spermatic cords in a 8 shape. there was an important point about...
