In this paper an algebraic technique for unbalance parameters identification along with an active control scheme for a rotor bearing system are presented. The system has two disks asymmetrically located along the shaft which is supported by a conventional ball bearing at one end and by an active suspension at the other one. The active suspension is based on linear springs and linear force actua...

Maria Olkkonen Terhi Mustonen Abstract — In this study, the effect of vibration on mobile-phone text legibility caused by walking was examined. Legibility was measured as reading performance and subjective task load when reading from a mobile-phone display while walking on a treadmill at 1.5 km/hour, 3 km/hour, and an individually defined speed (3.9 km/hour on average). Vibration was measured o...

hand-arm vibration can cause vascular, neurological and musculoskeletal disorders, collectively named as hand-arm vibration syndrome. the chainsaw is a portable machine that exposes own operators to high levels of hand-arm vibrations. this research focuses on vibration transmissibility from chainsaw handle to wrist and arm of operator. the vibration acceleration signals necessary for evaluation...

BACKGROUND The severity of myelomeningocele (MMC) stems both from a loss of neurons due to neural tube defect and a loss of function in viable neurons due to reduced movement experience during the first year after birth. In young infants with MMC, the challenge is to reinforce excitability and voluntary control of all available neurons. Muscle vibration paired with voluntary movement may increa...
