5. VibroSkate:VR Skateboard that Reproduce Vibration from Ground

Isolation of Performance Halls from Ground Vibration

One of the inherent characteristics of transportation systems, especially steel wheel and rail systems, is that vehicles running on the roadway or trackway generate vibration which transmits through the ground into nearby buildings. As our urban areas build up or are redeveloped, it is frequently desired for a variety of reasons to place a concert hall or theater in a location which is in close...

Longboard and skateboard injuries.

INTRODUCTION The causes and events related to skateboarding injuries have been widely documented. However, little is known about longboard-related injuries. With five deaths linked to longboarding in the United States and Canada in 2012, some cities are already considering banning the practice. This study compared the types and causes of longboarding-related injuries to those associated with sk...

Ground Motion and Vibration Issues for Accelerators

Ground motion and vibration can be a limiting factor in the performance of future colliders, in particular linear colliders and large hadron colliders. Investigations of ground motion have been carried out around the world for several decades. In this review, after brief discussion of ground motion requirements for NLC, TESLA and VLHC, the results of recent investigations of ground motion are p...

Propagation of Ground Vibration: a Review

An important environmental aspect of building and facility design is the evaluation of vibration transmitted to the site, through the ground, from external sources. Such external sources may include highway traffic, surface and subsurface railways, and machinery in nearby locations. To properly predict excitation levels at a building due to such sources, one must be able to predict how much vib...
