Friction-induced vibration of an elastic disc and a moving slider with separation and reattachment

The transverse vibration of an elastic disc, excited by a preloaded mass–damper–spring slider dragged around on the disc surface at a constant rotating speed and undergoing in-plane stick–slip oscillation due to friction, is studied. As the vertical vibration of the slider grows at certain conditions, it can separate from the disc and then reattach to the disc. Numerical simulation ...

The Influence of Different Movements on Ambulatory Blood Pressure in Hypertensive Subacute Stroke Patients

OBJECTIVE: This study evaluated variation in blood pressure (BP) in hypertensive subacute stroke patients performing eight different types of active movement, and variations in BP over time. METHODS: The study included 35 subacute stroke patients (60 – 74 years old) and 15 age-matched healthy volunteers. Ambulatory systolic and diastolic BP was measured over 4 consecutive days, ...
