For flow conduits with mild slope and considerably large vertical curvatures the hydrostatic distribution of the pressure may be used for design proposes. However, for the spillway chutes actual pressure load over the steep slope beds with small vertical curvatures may differ from the hydrostatic pressure values. The differences in pressure load on curved bed chutes are mainly because of the ce...

Abstract In a stepped spillway, the spillway face is provided with series of steps from near crest to toe. This type attractive for water resource management because it dissipates energy that within flow. When dissipated by steps, reduces reduction otherwise must occur at toe spillway. present study, nine physical models slopes 15, 25, 45° and number varying 5 50 have been constructed. The spil...

Abstract Energy dissipation is one of the important issues in piano key weirs (PKWs). Excessive energy at weir's toe can cause scouring. In previous studies, arced (APKWs) has not been investigated. this experimental study, effect weir height as well and arrangement baffles located on outlet slope amount dissipated were examined trapezoidal (TPKWs) APKWs. Experiments performed models with two t...

Playing the piano requires one to precisely position one’s hand in order to strike particular combinations of keys at specific moments in time. This paper presents the first system for automatically generating three dimensional animations of piano performance, given an input midi music file. A graph theory-based motion planning method is used to decide which set of fingers should strike the pia...

The present work is about the synthesis of piano sound based on the grounds of physical principles. For that, rst the acoustical properties of the piano have to be understood, since the underlying physical phenomena establish the framework for the model-based sound synthesis. Therefore, the di erent parts of the piano were measured and analyzed. The groundwork of the piano model lies in the dig...

We describe a new algorithm to transcribe musical note complexes from polyphonic piano music. Our method is a spectrogram based algorithm, which uses a robust peak detection scheme and forms note complexes by multiple sample conditional probability in the context of a time-frequency based finite state space approach, where note onsets are determined implicitly by changes in subharmonics. This p...

This paper provides an overview on the advances of music information retrieval in symbolic representation of music. Such musical aspects as key, tonality, bass, melody, dynamics, rhythm and patterns are considered as foundation for visualizing systems for the piano stream in classical music. The paper then describes the proposed visualizing system and Malinowski’s music animation machine. It la...

Here we propose a score-informed monaural source separation system to extract every tone from a mixture of piano tone signals. Two sinusoidal models in our earlier work are employed in the above-mentioned system to represent piano tones: the General Model and the Piano Model. The General Model, a variant of sinusoidal modeling, can represent a single tone with high modeling quality, yet it fail...
