The grand piano action is modeled as a set of four rigid bodies using Kane’s method. Computerized symbol manipulation is utilized to streamline the formulation of the equations of motion so that several models can be considered, each of increasing detail. Various methods for checking the dynamical model thus derived are explored. A computer animation driven by simulation of the equations of mot...

The onset of the piano tone shows interesting characteristics due to several efSects. At the very beginning of a note, a variety of transients are mixed, some of which are propagated via the strings, and others via the structure of the instrument. The details of the structure-born transients in a grand piano were studied by removing the strings for a note in the mid range and letting the hammer...

This paper presents a hardware and software system for adding multiple touch sensitivity to the piano-style keyboard. The traditional keyboard is a discrete interface, defining notes by onset and release. By contrast, our system allows continuous gestural control over multiple dimensions of each note by sensing the position and contact area of up to three touches per key. Each key consists of a...

Scour in bed material downstream weirs is considered the most unfavorable process which threats the overall stability of the weir. Weirs with oblique angle in the horizontal plan will affect the scour profile downstream the structure and may reduce it. The objective of this paper is to investigate the effect of oblique weir angle on the scour profile. Furthermore, the effect of V-notch angle on...

Orifice-weir structures at ditch outlets are proposed to reduce peak drainage rates during high flows and to store water during the growing season in poorly drained managed pine plantations. Two coastal watersheds, one conventionally drained (D1) and another with an orifice-weir outlet (D3), were monitored to examine the effects of this orifice treatment on drainage outflows and nutrient export...
