Numerical modelling of fault activities
Computers & Geosciences, 2007There is a fundamental connection between crustal strain (deformation) rates and seismic activity. To this end two FORTRAN utility programs have been developed, aimed at estimating the seismicity on a fault in cases when this cannot be done directly, or as a comparison with observed data.

Abstract The power of a fault rupture beneath a dam was demonstrated when there was about 8 m of vertical movement beneath gate 17 of the Shih-Kang weir in Taiwan on 21 September 1999. The downstream damage was, in this case, minimal, but the incident has made designers very wary of attempting to build dams across potentially active ...

Fault-tolerant model predictive control with active fault isolation
2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013A robust control method is presented for linear systems subject to input and state constraints, bounded disturbances and measurement noise, and discrete faults in sensors, actuators, and system dynamics. The approach uses set-based fault detection and isolation techniques to coordinate switching between controllers designed for each fault scenario.

Fault estimation and active fault tolerant control for servo systems
2016 IEEE International Conference on Real-time Computing and Robotics (RCAR), 2016In this paper, the problems of fault estimation and fault tolerant control for motor servo systems are investigated. The motor servo systems are modeled as continuous-time linear systems with unknown inputs and actuator faults. Based on the faulty system model, a robust fault estimation and active fault tolerant control scheme is proposed.

Scan Tests with Multiple Fault Activation Cycles for Delay Faults
24th IEEE VLSI Test Symposium, 2006In this paper we investigate methods to detect delay faults in circuits that use standard scan design. We demonstrate that delay faults at several sites in a circuit cannot be detected using standard launch off capture and launch off shift tests that use two test cycles.

Fault Activation During Hydraulic Fracturing
72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010, 2009Microseismic monitoring was used to image hydraulic fracturing during a gas well stimulation. Some time after the end of the injection, there was an increase in the seismic deformation rate. Investigation of the frequency-magnitude characteristics during the pumping phase were consistent with other hydraulic fracture results, although the activity ...

Mapping of active faults and their characterization will provide the first direct constraints in a region known to have earthquakes. There is an inherent relationship between active faults and earthquakes. Satellite image calibration, creation of epipolar geometry of stereopair data and DEM, active faults identifications, anaglyph perspective for 3D ...

Abstract This chapter traces some of the ideas and concepts leading to the current understanding of the process of faulting and earthquake generation, gives examples of engineering geology investigations contributing to that understanding, describes some engineering projects that have been strongly influenced by the process, and suggests

Providing the first worldwide survey of active earthquake faults, this book focuses on those described as 'seismic time bombs' – with the potential to destroy large cities in the developing world such as Port au Prince, Kabul, Tehran and Caracas. Leading international earthquake expert, Robert Yeats, explores both the regional and plate-tectonic ...
