Hard sphere colloidal particles are a basic model system for general research into phase behavior, ordering and out-equilibrium glass transitions. Experimentally it has been shown that oscillatory shearing of a monodisperse hard sphere glass, produces two different crystal orientations; a Face Centered Cubic (FCC) crystal with the close packed direction parallel to shear at high strains and an ...

OBJECTIVE The objective of this study is to examine ground kinetics early in stance while walking on a contaminated surface and assess the potential of kinetics to quantify risk of slipping. BACKGROUND Prior studies of slipping have dismissed early ground kinetic data,and therefore no prior literature has been able to assess the viability of using these data to quantify slip potential. METH...

Drawing from the rich source of proven and often novel mechanisms in the biological realm, biomimetic sensors are being successfully developed for many different transduction tasks. This paper presents such a sensor for transducing displacements. Our sensor is a robotic analog of the biological muscle spindle, an actuated position sensor which transduces muscle displacement for kinesthetic awar...
