We present a system for the transcription of polyphonic music recordings to recover both the notes played and the instruments responsible for each note. In our framework, the spectrogram of the music is viewed as the superposition of note events, each characterized by an onset time and pitch, an instrument (described by a vector of eigeninstrument weights that combine instrument model bases to ...

Viuhka is a compositional tool situated in PWGL. The system has been recently adapted in order to enhance our notation package. This paper contains a new notational short-hand, called macro-note, that can be used to realize short musical segments that have their lifespan within a macro-note. The system allows to generate various ornaments in the traditional sense, such as tremolos, trills, and ...

Effective competition for local monopoly cable systems would seem to offer a natural solution to nagging problems widely attributed to the cable industry, such as high prices and poor service. In regulatory and legislative proceedings leading up to the Cable Television Consumer Protection and Competition Act of 1992,(note 1) however, potential or existing competitors to local cable systems comp...

The note considers the -disturbance attenuation of multimachine power systems via dissipative pseudo-Hamiltonian realization of the systems. First, the note expresses multimachine systems as a dissipative Hamiltonian system. Then, the note investigates the energy-based control design of -disturbance attenuation of multimachine power systems and proposes a decentralized simple control strategy. ...

Interatomic potentials, which describe interactions between elements of nanosystems, are crucial in theoretical study of their physical properties. We focus on two well known empirical potentials, i.e. Tersoff's and Brenner's potentials, and compare their performance in calculation of thermal transport in carbon nanotubes. In this way, we study the temperature and diameter dependence of thermal...

Although digital devices are replacing paper and pencil in ever more domains, class notes have so far resisted this trend. In part this is because class notes and the note-taking process are unique and different from the tasks supported by existing software. A system to support classroom note-taking should embody seven design principles. A prototype system based on these principles was used in ...

This paper presents our recent work in developing a system for transcription of polyphonic piano music. Our goal is to build a system that would automatically transcribe polyphonic piano music from the audio signal, transcribing note onsets and offsets. The system consists of three main stages: filtering, partial tracking and note extraction. The paper presents our partial tracking method based...
