Phase Coexistence of Complex Fluids in Shear Flow
, 1999 We present some results of recent calculations of rigid rod-like particles in shear flow, based on the Doi model. This is an ideal model system for exhibiting the generic behavior of shear-thinning fluids (polymer solutions, wormlike micelles, surfactant

Buckling of elastic filaments by discrete magnetic moments
, 2017 We study the buckling of an idealized, semiflexible filament along whose contour magnetic moments are placed. {We give analytic expressions for the critical stiffness of the filament below which it buckles due to the magnetic compression.

A consistent treatment of link and writhe for open rods, and their relation to end rotation [PDF]
, 2003 We combine and extend the work of Alexander & Antman \cite{alexander.82} and Fuller \cite{fuller.71,fuller.78} to give a framework within which precise definitions can be given of topological and geometrical quantities characterising the contortion of ...

Rayleigh Wave Calibration of Acoustic Emission Sensors and Ultrasonic Transducers. [PDF]
, 2019 Acoustic emission (AE) sensors and ultrasonic transducers were characterized for the detection of Rayleigh waves (RW). Small aperture reference sensors were characterized first using the fracture of glass capillary tubes in combination with a theoretical
