Explosions near Isolated Unstable Attractors
We describe the set of explosive orbits in the region of attraction of an unstable attractor which is isolated in the sense of C.C. Conley. Sufficient conditions are given for the existence of explosions in certain parts of the region of attraction and for an unstable attractor to have finitely generated integral Alexander-Spanier cohomology groups. Finally, we study the case of singularities t...
متن کاملGround 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...
متن کاملPropagation 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...
متن کاملIsolation 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...
متن کاملVibration Analysis of Global Near-regular Mechanical Systems
Some near-regular mechanical systems involve global deviations from their corresponding regular system. Despite extensive research on vibration analysis (eigensolution) of regular and local near-regular mechanical systems, the literature on vibration analysis of global near-regular mechanical systems is scant. In this paper, a method for vibration analysis of such systems was developed using Kr...
