Determining the seismic fracture energy during an earthquake and understanding the associated creation and development of a fault zone requires a combination of both seismological and geological field data. The actual thickness of the zone that slips during the rupture of a large earthquake is not known and is a key seismological parameter in understanding(More)
Research has been carried out in four distinct areas related to geologic storage of CO 2 : geophysical monitoring strategies of sequestration sites (Professor Harris), the feasibility of CO 2 sequestration in coal (Professor Kovscek), the utilization of CO 2 for extinguishing coal bed fires (Professor Orr) and the feasibility of sequestering CO 2 in(More)
The in-situ stress state in the Tarim Basin, Northwest China, down to 7 km depth is constrained using the anelastic strain recovery (ASR) method and wellbore failure analysis. Results are consistent between the two methods, and indicate that the maximum principal stresses (σ1) are close to vertical and the intermediate and minimum principal stresses (σ2 and(More)
This work describes how to use reactionless motion control with a free-floating space robot, suggesting thereby some tasks of practical importance. We show that the reactionless motion capability is directly affected by the kinematic structure of the manipulator, depending thereby upon the existence of kinematic redundancy, a typical lower/upper arm(More)
