Neurology, 1998
Recent reports have emphasized the role of roller-coaster rides in the occurrence of neurologic complications such as cervical artery dissections,1 chronic subdural hematoma,2,3 subarachnoid hemorrhage,4 and spinal CSF leak.5 We report a patient with a previously asymptomatic syringomyelia and Chiari malformation who presented with acute neurologic ...

Correction of the roller generators in spherical roller bearings
Wear, 1996The subject of this work is the optimization of correction of the roller generators in the spherical roller bearing. Arch correction, resulting from the bearing construction, and arch-logarithmic correction have been discussed herein. In the studies on the effect of correction parameters on the contact capacity, the authors used a computer program ...

Proceedings IEEE Virtual Reality 2000 (Cat. No.00CB37048), 2002
Roller coasters are an attractive, adventurous and exciting form of entertainment. In this paper, we present a virtual roller coaster system, which includes roller coaster simulation software, a motion platform and a motion control unit. We investigate the track structure of the roller coaster and propose a methodology to generate the track ...

Mechanics of Roller Instability in Roller Bearings.
1978Abstract : An analytical formulation for the roller motion in a cylindrical roller bearing is presented in terms of the classical differential equations of motion. Roller-race interaction is analyzed in detail and the resulting force and moment vectors are determined.

Journal of Neuroscience Methods, 1987
A roller pump is described which is able to pump microlitre quantities of solution in either direction. It depends upon a caged roller bearing where the individual rollers press against silicon rubber tubing having an internal diameter of 0.5 mm. This assembly was housed in a cylindrical cavity shaped to produce a non-pulsatile flow. The pump is driven
