Banded Waveguides on Circular Topologies and of Beating Modes: Tibetan Singing Bowls and Glass Harmonicas

Debris elimination from partially-filled cell salvage bowls.

Centrifuge-based cell salvage and washing systems, available since the 1970s, have decreased the use of allogeneic blood transfusions (1). Although intraoperative salvage and autotransfusion avoids the risks of allogeneic transfusion, case reports document adverse reactions to this blood, potentially related to inadequate washing (2). The cleanliness of partially filled cell salvage bowls has b...

Tibetan singing bowls

We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behaviour is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl’s natural vibrational modes ...

Building Bowls for Miscellaneous Media

The features we present of the augmented bowl have been designed to exploit our commonsense understandings and everyday uses of container-like objects. As we’ll explain, in choosing the features, we’ve attempted to build on the ways in which physical content can be casually added to or retrieved from a bowl with little to no thought. We’ve also tried to capture the way bowls loosely contain the...

Groups of banded matrices with banded inverses

AproductADF1 : : : FN of invertible block-diagonalmatrices will be bandedwith a banded inverse. We establish this factorization with the numberN controlled by the bandwidthsw and not by the matrix size n:When A is an orthogonal matrix, or a permutation, or banded plus finite rank, the factors Fi have w D 1 and generate that corresponding group. In the case of infinite matrices, conjectures rema...
