To establish the design requirements for an MR-compatible haptic hand-controller, this paper measures magnitudes and frequency bands of three mechanical motion and interaction components during the performance of neurosurgical tasks on a cadaveric brain. The hand-controller would allow the performance of virtual neurosurgical tasks within the bore of a high(More)
The contact behavior of drillstring and wellbore is of great concern to drilling companies in the oil and mineral exploration industries. Due to the nonlinear, random motion of the drillstring in contact with the wellbore, it is difficult to predict the response of the drillstring. Successive contacts of wellbore and drillstring will result in fatigue(More)
