Wrinkling in engineering fabrics: a comparison between two different comprehensive modelling approaches [PDF]
, 2018 We consider two ‘comprehensive’ modelling approaches for engineering fabrics. We distinguish the two approaches using the terms ‘semi-discrete’ and ‘continuum’, reflecting their natures.

Tunable sensor response by voltage-control in biomimetic hair flow sensors [PDF]
, 2013 We present an overview of improvements in detection limit and responsivity of our biomimetic hair flow sensors by electrostatic spring-softening (ESS). Applying a DC-bias voltage to our capacitive flow sensors improves the responsively by up to 80% for ...

An Analysis of Traction Drive Torsional Stiffness [PDF]
Journal of Mechanisms, Transmissions, and Automation in Design, 1985 An analysis of the tangential compliance of elastic bodies in concentrated contact is applied to traction drive elements to determine their torsional stiffness. Both static loading and rotating conditions are considered. The effects of several design variables are shown. The theoretical torsional stiffness of a fixed ratio multiroller traction drive is
