Harmonics of <i>S</i> motion on bowed strings
Lossless bowed strings have usually been thought to possess a motion discovered by Helmholtz in 1863. However, it was shown [Acustica 44, 194-206 {1980)] by the author that a more complicated standing wave motion, the $ motion, exists on such strings provided both the bowing distance and bowing force are above certain minimum values. This paper explores S-motion harmonics which give arise to wa...
متن کاملNonlinear Commuted Synthesis of Bowed Strings
A commuted-synthesis model for bowed strings is driven by a separate nonlinear model of bowed-string dynamics. This gives the desirable combination of a full range of complex bow-string interaction behavior together with an efficiently implemented body resonator. A “single-hair bow” may control a pulsed-noise version which provide the effects of multiple bow hairs. The pulsed noise may also inc...
متن کاملAn Investigation of the Impact of Torsion Waves and Friction Characteristics on the Playability of Virtual Bowed Strings
Playability” is measured for variations in a bowed-string simulation model. The variations studied are (1) the effect of torsion waves, and (2) the effect of the choice of friction model. It is found that (1) elimination of torsion-wave simulation does not degrade playability, and (2) the more recently developed “plastic” bowedstring friction model, in which the frictional force is a function o...
متن کاملA Player Model for Midi Control of Synthetic Bowed Strings
As the underlying physical processes of bowed string instruments have been investigated extensively and are understood well, it becomes clear that the instrument model on its own is not sufficient for realistic synthesis of bowed strings. Controlling the parameters for the excitation of the string model is comparable to playing the real instrument, and the design of algorithms controlling the a...
متن کاملHeterotic Strings with Torsion
In this paper we describe the heterotic dual of the type IIB theory compactified to four dimensions on a toroidal orientifold in the presence of fluxes. The type IIB background is most easily described in terms of an M-theory compactification on a four-fold. The heterotic dual is obtained by performing a series of U -dualities. We argue that these dualities preserve supersymmetry and that the s...
