We demonstrate a novel instability found within unconfined viscous bands/rims, or free-surface flows involving longitudinal viscosity contrast. Such instabilities may be described as banding instabilities, non-porous fingering of the intrusion less fluid into band more fluid. A consequence this work is that widely known to occur in porous media following seminal Saffman & Taylor ( Proc. R. ...

Introduction To the aims of investigating the automatic music performance, that is in computing gestures and controls and in transmitting them to sound synthesis equipment [Roads, 1985], we pursue an approach that is cognition-based, and relies on a physical model in order to define a strict relationship between the score in input and the sound produced. The music performance process involves s...

In dielectric breakdown, the phenomena of streamers formation and spontaneous branching is commonly observed. A deterministic negative streamer model is reviewed in this article. We recently have proposed that this reduced model is able to explain the branching phenomena, due to a Laplacian instability quite like in viscous fingering. Particular attention is paid to the physical interpretation ...

The musical quality of computer-generated performances of piano scores might be improved by incorporating a physical model of the pianist’s body as it interacts with the instrument. Issues considered include the various aspects of musical structure (as conceived by a virtual pianist) that interact with expression, and the expressive function and algorithmic determination of fingering (as used b...
