Design of compliant mechanisms for attenuation of unidirectional vibrations in rotational systems
… undesired small-motion angular vibrations in rotational power transmission systems and (2) preserve the desired transmission of large-motion torque/angle inputs. This thesis investigates the design of vibration attenuating compliant mechanisms that are directly integrated into the load path of …

Reduction of energy losses: a key to improved rock drilling?
The viscous power losses of a rotary-vibratory drilling system are estimated in this study. Rotational and pure vibratory losses are considered separately. This analysis indicates that considerable power is dissipated into the drilling fluid. Pure vibratory power losses of over 3,728 W (5 hp) are …

An investigation into the use of linear generators in the Schneider Hydro-Power Generation system
… HydroBeaver is a revolutionary idea in Hydro-Power Generation. Conventional dams employ the use of turbines which require a large head to generate the power. The large head is developed through dams, which alter the natural course of rivers, destroying fertile river valleys and ruining the …

Acute and Chronic Foam Rolling in NCAA Division II Female Golfers
… measured using the 7-iron and driver. Muscular power was assessed using the countermovement jump and medicine ball throws. A 1-repetition maximum was estimated from a 3-5 repetition strength test. Body composition was determined using bioelectrical impedance (BIA), flexibility was assessed using …

An Investigation of Technique and Equipment Factors Associated with Clubhead Speed in Golf
… as height and physical factors such as trunk rotational power have been previously considered to be of importance. However, biomechanical factors such as; the X-factor (separation of the trunk-pelvis alignment when viewed in the transverse plane), have been a major focus of recent research. …
