Eigenmodes and tone quality of the double bass

The low down on the double bass: looking for the effects of torsional modes

The action of the bow produces torsional oscillations in a string, as well as the normal transverse motion [1]. The torsional modes have frequencies several times higher than, and not harmonically related to, the transverse modes. Via the strongly non-linear bow-string interaction, the torsional modes are driven at a harmonic of the translational modes [2]. The torsional mode frequencies for wo...

SABRe: The Augmented Bass Clarinet

An augmented bass clarinet is developed in order to extend the performance and composition potential of the instrument. Four groups of sensors are added: key positions, inertial movement, mouth pressure and trigger switches. The instrument communicates wirelessly with a receiver setup which produces an OSC data stream, usable by any application on a host computer. The SABRe projects intention i...

Effects of Temperature on the Susceptibility of Largemouth Bass to Largemouth Bass Virus

—Temperature is an environmental variable thought to influence the susceptibility of fish to infectious diseases. This study demonstrated that juvenile largemouth bass Micropterus salmoides that were experimentally infected with largemouth bass virus (LMBV; family Iridoviridae) experienced greater mortality at 308C than at 258C. Juvenile largemouth bass were exposed to equal doses of LMBV and h...

Hierarchical Bass model

We propose a new model about diffusion of a product which includes a memory of how many adopters or advertisements a non-adopter met, where (non-)adopters mean people (not) possessing the product. This effect is lacking in the Bass model. As an application, we utilize the model to fit the iPod sales data, and so the better agreement is obtained than the Bass model.
