The charged bouncing ball: An experimental model for period-doubling bifurcation
(IOP Publishing Ltd., 1997-03-10)
This paper presents an experimental and theoretical study of the dynamics of a conducting ball in a poorly conducting liquid subjected to an electric field. When the applied voltage is constant the ball bounces regularly ...

An automated apparatus for measuring the tensile strength and compressibility of fine cohesive powders
(American Institute of Physics, 2000)
This paper describes an apparatus based on a novel use of a powder bed, whereby the relationship between consolidation stress, tensile strength, and free volume of fine powder is measured. The powder to be tested is first ...

Flow Regimes in Fine Cohesive Powders
(American Physical Society, 1999)
Granular materials exhibit several regimes of behavior: plastic, inertial, fluidized, and entrained flow, but not all materials can pass through all of these states. Our concern is with the criteria that determine the ...
