Under the guidance of petroleum geology, on basis in-depth understanding geological characteristics D block such as structure and sedimentation law oil gas enrichment, this paper discusses reservoir potential selects target block. The study shows that is a fault nose controlled by reverse normal fault, has controlling effect its provenance, formation distribution.

This research aims to examine the relationship between hydrothermal alteration and mineralization (ore mineralogy) in study area geological structures deformation mechanism. The was determined based on petrographic analysis, ore mineralogy which microscopic analysis. mechanism is by paleo stress analysis using win-tensor, direction of principal joints/veins faults calculated right-dihedron meth...

[1] We perform two-dimensional dynamic models of strike-slip faults with a change in strike (a bend) over multiple earthquake cycles to examine the long-term effects of nonplanar fault geometry. A viscoelastic model (a proxy for off-fault deformation and tectonic loading) is introduced for the interseismic process to avoid pathological stress buildup around the bend. A finite element method wit...

This paper discusses the application of weighted fuzzy reasoning spiking neural P systems (WFRSN P systems) to fault diagnosis in traction power supply systems (TPSSs) of China high-speed railways. Four types of neurons are considered in WFRSN P systems to make them suitable for expressing status information of protective relays and circuit breakers, and a weighted matrix-based reasoning algori...

Extracting fault, unconformity, and horizon surfaces from a seismic image is useful for interpretation of geologic structures and stratigraphic features. Although interpretation of these surfaces has been automated to some extent by others, significant manual effort is still required for extracting each type of these geologic surfaces. I propose methods to automatically extract all the fault, u...

Substantial damage may occur when a rotary actuator fails during operation. Therefore, effective fault diagnosis of a rotary actuator is crucial to ensuring the safety of the device. However, only a few studies on fault detection, fault isolation, and performance assessment have focused on rotary actuators. In this study, fault detection and fault isolation processes were implemented by designi...

This paper presents DE/IFT, a new fault diagnosis engine which is based on the authors’ IFT algorithm for induction of fault trees. It learns from an examples database comprising sensor recordings, all of which have been classified as corresponding to either the normal behaviour of the system or to one or more fault states. The fault trees generated by IFT are translated into functions in the C...

[1] The 2006 Mw7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane ( 75°). The amount of slip in the earthquake decreased from depths of 10 km toward the surface, and this shallow slip deficit was at least partly recovered by postseismic afterslip on the shallow part of the fault plane. An adjacent normal fault segment slipped postseismically (a...

This paper describes a new Artificial Neural Network (ANN) based digital differential protection scheme for generator stator winding protection. The scheme includes two Feedforward Neural Networks (FNNs). One ANN is used for fault detection and the other is used for internal fault classification. This design uses current samples from the line-side and the neutral-end in addition to samples from...
