Determining the composition and physical properties of shallowdipping, active normal faults (dips , 358 with respect to the horizontal) is important for understanding how such faults slip under low resolved shear stress and accommodate signi®cant extension of the crust and lithosphere. Seismic re ̄ection images and earthquake source parameters show that a magnitude 6.2 earthquake occurred at abo...

Surface deformation accompanying dike intrusions is dominated by uplift and horizontal motion directly related to the intrusions. In some cases, it includes subsidence due associated magma reservoir deflation. When deflation large enough, can form, or reactivate preexisting, caldera ring-faults. Ring-fault reactivation, however, rarely observed during moderate-sized eruptions. On February 21, 2...

Fault trees provide a graphical and logical framework for analyzing the reliability of systems. A fault tree provides a conceptually simple modeling framework to represent the system-level interactions between component reliabilities. Dynamic fault trees have been shown particularly useful for reliability analysis of embedded computer systems. Dynamic fault trees are a superset of traditional (...

T he Bight Basin is a major frontier basin of Jurassic–Cretaceous age, which is currently undergoing renewed exploration interest. Although only limited data is available for understanding the petroleum systems in the basin, several observations indicate that poor fault seal integrity may represent a key exploration risk. The presence of a paleo-oil column in the Jerboa-1 well, interpreted gas ...

detecting anomalies is an important challenge for intrusion detection and fault diagnosis in wireless sensor networks (wsns). to address the problem of outlier detection in wireless sensor networks, in this paper we present a pca-based centralized approach and a dpca-based distributed energy-efficient approach for detecting outliers in sensed data in a wsn. the outliers in sensed data can be ca...

Received May 23, 2012 Revised Aug 12, 2012 Accepted Aug 23, 2012 In this paper, an accurate method for determination of fault location and fault type in power distribution systems by neural network is proposed. This method uses neural network to classify and locate normal and composite types of faults as phase to earth, two phases to earth, phase to phase. Also this method can distinguish three...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....

Given the problems in intelligent gearbox diagnosis methods, it is difficult to obtain the desired information and a large enough sample size to study; therefore, we propose the application of various methods for gearbox fault diagnosis, including wavelet lifting, a support vector machine (SVM) and rule-based reasoning (RBR). In a complex field environment, it is less likely for machines to hav...

We describe the morphology of a large and complex graben structure in the western Thauma-sia region (the " Thaumasia graben " [1] or TG). We consider possible fault geometries, determine extension , and discuss shortly possible models for its origin. Background: Situated at the western border of the Thaumasia plateau, the TG is one of the most prominent fault-bounded structures on Mars. It is ~...
