[1] We discuss numerical simulations of evolving fault zone structures in a 3-D lithospheric model with a seismogenic crust governed by a damage rheology that accounts for large strain associated with permanent brittle deformation. Results for the initial propagation of an existing narrow damage zone subjected to oblique loading exhibit strong asymmetry of the evolving damage with respect to th...

[1] We present anisotropy measurements from shear wave splitting along the Hector Mine rupture zone. Six major arrays were deployed in four locations in the year following the M7.1 Hector Mine earthquake. The dense station coverage, wide distribution of the arrays, and repeated deployments show a clear predominant fast direction and spatial variation of splitting along the fault but no resolvab...

In this paper, in view of the advantages of widely used Proportional-Integral-Derivative (PID) controller and gain scheduling control strategy in aerospace and industrial applications, a control strategy by using gain scheduling based PID controller is proposed for fault tolerant control (FTC) of a quad-rotor Unmanned Aerial Vehicle (UAV). The nonlinear dynamic equations of motion of the quad-r...

In a 1.140 km² study area of the volcanic West Eifel, a comprehensive investigation established the correlation between red wood ant mound (RWA; Formica rufa-group) sites and active tectonic faults. The current stress field with a NW-SE-trending main stress direction opens pathways for geogenic gases and potential magmas following the same orientation. At the same time, Variscan and Mesozoic fa...

this study extends prior researches by exploring the effect of organizational orientations on export performance. building on the already extensive literature, we developed a model of relationship. a total of 120 usable questionnaires were received from the iranian food industry smes. the results indicated that entrepreneurial orientation, market orientation and learning orientation positively ...

PS seismic data from the Snøhvit field are compared with modelling to understand effect of azimuthal separation and incidence angle on imaging faults associated horizon discontinuities. In addition, frequency content waves backscattered is analysed. The study area consists a horst structure delimited by northern fault dipping NW oblique E-W survey orientation, southern SSW subparallel survey. D...

a r t i c l e i n f o Increasing use of diffraction methods to study preferred orientation of minerals has established that quartz in deformed rocks not only displays characteristic c-axis orientation patterns, but that there is also generally a distinct difference in the orientation of positive and negative rhombs. In the trigonal quartz crystal structure positive and negative rhombs are struc...

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 ...

We present an inversion strategy capable of using real-time high-rate GPS data to simultaneously solve for a distributed slip model and fault geometry in real time as a rupture unfolds. We employ Bayesian inference to find the optimal fault geometry and the distribution of possible slip models for that geometry using a simple analytical solution. By adopting an analytical Bayesian approach, we ...
