In the two-dimensional discrete element modeling of displacement of sedimentary layers caused by faulting within the basement, we attempted to move a rigid basement as if it were an elastic basement by controlling its motion through application of dislocation solutions. An advantage of our modeling procedure is that we can discuss displacement fields of sedimentary layers in connection with fau...

Theoretical research and equipment development of traveling-wave fault location seriously depend on digital simulation. Meanwhile, the fault-generated transient traveling wave must be transferred through transmission line, mutual inductor and secondary circuit before it is used. So this paper would maily analyze and summarize the modeling technology of transmission line and mutual inductor on t...

Fault tolerant circuits are currently required in several major application sectors. Besides and in complement to other possible approaches such as proving or analytical modeling whose applicability and accuracy are significantly restricted in the case of complex fault tolerant systems, fault-injection has been recognized to be particularly attractive and valuable. Fault injection provides a me...

The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to sugg...

When a new system is developed, an evaluation of the system reliability should be carried out in order to determine whether the system is acceptable for an actual spot. Reliability of systems in a nuclear power plant is also analyzed to compare with regulatory criteria designed to ensure the availability of high-quality qualifications. There are several reliability analysis methods: the fault t...

Model-Based Fault Detection and Identification for Power Electronics Systems by Jason Poon Master of Science in Electrical Engineering and Computer Sciences University of California, Berkeley Professor Seth R. Sanders, Chair We present the analysis, design, and experimental implementation of a model-based fault detection and identification (FDI) method for switching power converters based on a ...

Fault zones are thought to consist of regions with reduced seismic velocity. When sources are located in or close to these low-velocity zones, guided seismic head and trapped waves are generated which may be indicative of the structure of fault zones at depth. Observations above several fault zones suggest that they are common features of near fault radiation, yet their interpretation may be hi...

Many approaches have been developed to detect and diagnose the different types of faults that may occur in a complex process. Most of these approaches have traditionally been based on linear modeling techniques, which restricts the type of practical situations that can be modeled. Recently, many learning based non linear modeling using neural and other on-line approximation models have been dev...

This paper presents a complete scheme for protection of transmission lines, including fault detection, fault classification as well as fault location. The fault location module utilizes the modeling of transmission lines through their differential equations. The differential equation for the line is solved having its resistence and inductance as parameters. In this approach there is no need for...
