Full textAt the static level, structural properties determined by a reconvergent fanout analysis are used to reduce the explicit simulation of fanout stem faults. At the dynamic level, dependencies between fault detectabilities are identified and used to reduce both the critical path tracing and explicit simulation components. In addition, fault-free simulation is reduced by tracking areas outside of which it is not required. The dynamic analysis reduces the fault simulation even further through a selective choice of the order in which the three simulation components are performed.

Full textAlthough fault zones represent a very small volume of the crust, they highly influence the crust’s mechanical and fluid flows properties. This work compares high definition trans-disciplinary analyses of two fault zones with highly contrasted properties. One is a mature fault zone of plurikilometer length, and the other is a small fault zone of a few hundred meters length. We have characterized the architectural, hydromechanical and strength properties of these faults to improve the understanding of the coupling between fault zones hydromechanical properties and their potential activation. A protocol to characterize in the field (on outcropping segments) the faults hydraulic and mechanical properties has been conducted through the coupling of micro-structural analyses, detailed rock physical descriptions at the rock mass several scales. The two studied fault zones despite their different sizes display some similarities. Both show a strong coupling between the fault zone diagenetic history, the initial properties of the sedimentary layers and the fault zone current hydraulic and mechanical properties. We show that the most important parameter governing the hydromechanical behaviors of fault zones is the continuity of the damage zones. A mature fault zone will have a relatively continuous damage zone while a small fault zone will contain a more heterogeneous damage zone characterized by an alternation of fractured and un-fractured layers. These architectural contrasts of damage zones also depend on the initial intact rock properties of the sedimentary series. Contrasted initial intact rock strengths (σc) induce contrasted strain accommodation mechanisms in the fault zone compartments, and an associated fault zone architecture that displays large thickness variations, characterized by alternate high-permeable-low-stiff and low-permeable-high-stiff layers in the damage zone

Full textThis dissertation presents the collection and processing of dense high-precision geode- tic data across major faults throughout Southern California. The results are used to inform numerical models of the long-term slip rate and interseismic behavior of these faults, as well as their frictional and rheological properties at shallow depths. The data include campaign surveys of dense networks of GPS monuments crossing the faults, and Interferometric Synthetic Aperture Radar (InSAR) observations from ENVISAT. Using a Bayesian framework, we first assess to what extent these data constrain relative fault slip rates on the San Andreas and San Jacinto faults, and show that the inferred parameters depend critically on the assumed fault geometry. We next look in detail at near-field observations of strain across the San Jacinto fault, and show that the source of this strain may be either deep anomalous creep or a new form of shallow, distributed yielding in the top few kilometers of the crust. On the San Andreas fault, we show that this type of shallow yielding does occur, and its presence or absence is controlled by variations in the local normal stress that result from subtle bends in the fault. Finally, we investigate shallow creep on the Imperial fault, and show that thanks to observations from all parts of the earthquake cycle it is now possible to obtain a strong constraint on the shallow frictional rheology and depth of the material responsible for creep. The results also suggest activity on a hidden fault to the West, whose existence has been previously suggested but never confirmed.

Full textFault zones strongly impact carbonates reservoir properties as they can act as drains or barriers depending of their structural and diagenetic properties. Hence, it is important to have an integrativecomprehension of these properties that affect the fault zones hydraulic properties. To this end, the multidisciplinary approach of this thesis combining structural, diagenetic and geochemical approaches aims to (1) constrain the structural and diagenetic evolution of fault zones in carbonates (2) draw rules and geometrical concepts allowing building of coherent geological models, and (3) allow a better understanding of the hydraulic dynamic response of fault zones in carbonates through their evolutions. We studied 3 fault zones (Castellas, D19) affecting lower Barremian platform carbonates (Urgonian facies) located in La Fare and Nerthe anticlines (Provence – SE France). This work allowed the restoration of fault zones diagenetic sequences with cement analyses under catholuminescence and 13C and 18O isotopes. The structural analysis completed the diagenetic evolution by determining the architectural characteristics related to each fault activity and discriminating the effect of pre-existing structures on subsequent fault development. Finally, this study improved our understanding of fault zones hydraulic behaviour in carbonates through times

Full textMotivated by the requirements of the space domain in terms of on-board diagnosis and autonomy, this thesis addresses the problems of diagnosis, diagnosability and active diagnosis of hybrid systems. Supported by a hybrid modeling framework, a passive approach for model-based diagnosis mixing discrete-event and continuous techniques is proposed. The same hybrid model is used to define the diagnosability property for hybrid systems and diagnosability criteria are derived. When the diagnosis provided by the passive diagnosis approach is ambiguous, active diagnosis is needed. This work provides a method for performing such active diagnosis. Starting with an ambiguous belief state, the method calls for diagnosability analysis results to determine a new system configuration in which fault candidates can be discriminated. Based on a new finite state machine called the diagnoser, the active diagnosis is formulated as a conditional planning problem and an AND-OR graph exploration algorithm is proposed to determine active diagnosis plans. Finally, the diagnosis approach is tested on the Attitude Control System (ACS) of a satellite simulator provided by Thales Alenia Space. The diagnosis module is successfully tested on several fault scenarios and the obtained results are reported
Chu, Hoang-Nam. "Test et évaluation de la robustesse de la couche fonctionnelle d'un robot autonome." Thesis, Toulouse, INPT, 2011. http://www.theses.fr/2011INPT0054/document.
Full textThe implementation of autonomous systems requires the development and the using of multi-layer software architecture. Typically, a functional layer contains several modules that control the material of the system and provide elementary services. To be robust, the functional layer must be implemented with protection mechanisms with respect to erroneous or inopportune requests sent from the superior layer. We present a methodology for robustness testing these mechanisms. We define a general framework to evaluate the robustness of a functional layer by characterizing its behavior with respect to inappropriate requests. We also propose an validation environment based on fault injection in the control software of a simulated robot. A great number of test cases is generated automatically by the mutation of a sequence of valid requests. The descriptive statistics of the behaviors in the presence of inappropriate requests are analyzed in order to evaluate the robustness of the system under test

Full textFault zones concentrate fluids migration and deformations in the upper crust. The shale hydraulic properties make them excellent storage sites and hydrocarbon reservoirs/source rocks. Fault zones can play two roles in the fluid circulation; drains or barriers, in general, both roles are combined within the same fault zone. What are the conditions that promote the fluid circulation along the fault zones in shales and what are the fault zone impacts on the formation properties are relatively poorly explored key questions. This study focused on characterizing the relationships between fault architecture, paleo-fluid as well as current fluid circulations through the analysis of fault calcite mineralization, injection tests and petrophysical properties conducted on a fault zone outcropping underground in the Tournemire research laboratory nested in the Toarcian shale. The fault zone structure was characterized using boreholes data and reconstructed in 3D through modeling to define different deformation facies. No clear facies organization is observed, a fault core and a fault damage zone being difficult to define as it is in hard rocks. The intact, fractured and breccia facies are characterized by a porosity of 9.5-13.5, 10-15 and 13-21%. Large fluid flowrate concentrated along a few “channels” located at the breccia boundaries and in the secondary fault zones that displayed fractured facies and limited breccia fillings. Detailed microstructural and geochemical analysis at the breccia/fractured zones interface revealed that fluids circulated out of the main shear zones, in micro-more or less inherited fractures highlighting a decoupling between fault slip and fluid migrations

The diagnosis of incipient fault in power transformers immerses in oil are directly related to the assessment of the isolation system conditions. This search is about the relationship between dissolved gases and the quality of the insulating mineral oil used in power transformers. Artificial Neural Networks are used to approach operational conditions assessment issue of the insulating oil in power transformers, which is characterized by a nonlinear dynamic behavior. The operation conditions and integrity of a power transformer can be inferred by analysis of physicochemical and chromatographic (DGA â Dissolved Gas Analysis) profiles of the isolating oil. This tests allow establishing procedures for operating and maintaining the equipment and usually are performed simultaneously. This work proposes a method that can be used to extract chromatographic information using physicochemical analysis through Artificial Neural Networks. The present analysis of physicochemical properties only provide a diagnostic tool for the oil quality, which does not allow the diagnosis of incipient faults. ItÂs believed that, the power utilities could improve reliability in the prediction of incipient failures at a lower cost with this method, since only one test is required. The results show this strategy might be promising with an average accuracy for diagnosis of faults greater than 72%. The purpose of this work is the direct implementation of the diagnosis of incipient faults through the use of physicochemical properties without the need to make an oil chromatography.

Full textI examine the relations between the properties of long-term geological faults and the properties of the large earthquakes these faults produce. I have gathered available seismological information on large historical earthquakes worldwide and mapped in detail, on satellite images, both the long-term fault and the rupture traces. The combined analysis of the data shows that: i) long-term faults have a number of generic properties (arrangement of overall fault networks, lateral segmentation of fault traces, form of cumulative slip distribution, etc); ii) large earthquakes also have generic properties (similarity of envelope shape of coseismic slip-length profiles, of decrease in rupture width along rupture length, of number of broken segments, of stress drop on broken segments, of relative distance between hypocenter and zone of maximum slip, etc); iii) the structural maturity of the faults is the tectonic property most impacting the behavior of large earthquakes. The maturity likely acts in reducing both the static friction and the geometric complexity of the fault plane. It partly governs the location of the earthquake initiation, the location and amplitude of the maximum coseismic slip, the direction of the coseismic slip decrease, the rupture propagation efficiency and speed, the number of major fault segments that are broken, and hence the rupture length and its overall stress drop. To understand the physics of earthquakes, it thus seems necessary to analyze jointly the tectonic properties of the broken faults and the seismological properties of the earthquakes

Full textRecent deep marine sedimentation in subduction trenches is characterized by the inter-stratification of hemipelagic and turbidite sediments locally interbedded with debris flow, which can result from continental slope shaking triggered by earthquakes. The active margin of Ecuador comprises tectonic erosion that contributes to the formation of a deep trench filled by a complex suite of sedimentary facies. Gravity flow sedimentation is ubiquitous along the margin and facies range from laterally continuous m-thick mass transport deposits to isolated cm-thick turbidites intercalated with hemipelagite, volcanoclastics and tephra. In this study we show interpretation of swath bathymetry, high-resolution seismic profiles and petrophysical data from cores. The objective is to describe the morphologic complexity on the Ecuadorian border of the Nazca plate where a set of deep marine asperities is subducting at different scales, and their consequences on the distribution of sediments in the different sub-basins. Ecuadorian margin comprises three geomorphological segments: The northern segment, northward of the Carnegie Ridge, is characterized by a wide (5-10 km) and deep trench (3800 – 4000 m), a gentler gullied continental slope and a shelf (10-40 km wide) with active subsidence. The central segment facing the Carnegie Ridge, is strongly influenced by the subduction of the Carnegie ridge which induces a narrow (0–5 km wide) and shallow trench (3100 – 3700 m depth), a steep and gullied slope with no canyons and a 15–40 km wide shelf characterized by areas with active subsidence and uplift. Finally, the southern segment, southward of the Carnegie Ridge, presents a wide (5–10 km) and deep (4000–4700 m) trench, a starved continental slope with well-defined canyon systems and a wide subsiding shelf (20–50 km). The sedimentary dynamics along the margin is evaluated by the analysis of 15 cores. Visual description, high-resolution photographs, X-Ray imagery, XRF data and petrophysical properties led to the identification of 11 sedimentary facies that characterize seven sedimentary processes: turbidites, hemipelagites, tephras, debris flows, homogenites, slumps, and ooze carbonate deposits. Age of the deposits is defined by radiocarbon age dating of hemipelagic sediments. Ages range from 500 to 48,000 years BP. High-resolution seismic profiles allow definition of three echo-facies: transparent, layered and chaotic. Transparent echo-facies is mainly associated to homogenite deposits, layered echo-facies is associated to the turbiditic-hemipelagic interbedded deposits and chaotic echo-facies is associated to reworked gravity flow deposits. The trench fill represents a lacunar but important record of the subduction margin history. Large eastward debris flows in the lower two sequences of the trench fill are provided by the trench outer wall as a results of slope failures along normal faults due to the downward bending of the oceanic plate. The sediment of the upper sequence of the trench fill draping the trench floor, are largely provided by the inner trench wall strongly controlled by the Carnegie Ridge. As a result, depth, frequency, thickness, composition and lateral disposition of the deposits vary greatly from those at north and south. The large, simple mega-beds like slump, debris flows and homogenites are located at the northern and southern segments. They were triggered by large regional faults in the North and enhanced by the activity of sets of splay faults in the South overhanging the seafloor at the slope toe. Small-size, fluid rich events were triggered by subduction of isolated seamounts at the edges of the Carnegie Ridge due to frequent but small destabilizations of an inner trench wall preconditioned by the impacts of successive seamounts. Sets of partly volcanoclastic turbidites in central segment might have been triggered by the complex interaction of slope and continental shelf deformation by seamount subduction

With the rapid development of VLSI technology, a multiprocessor system may contain hundreds or even thousands of processors. Some of these processors may be faulty while the system is put in use. This motivates us the issues of fault-tolerant properties of multiprocessor systems. There are some popular and interesting fault-tolerant properties for multiprocessor systems such as graph embedding and system diagnosis. In this dissertation, we demonstrate our work in two aspects. The first is fault-tolerant graph embedding, and the second is fault diagnosis. Let F_v be the set of faulty nodes in a system. For fault-tolerant graph embedding, we first show that an n-dimensional M?bius cube MQ_n with at most n-1 faulty elements contains a fault-free Hamiltonian path for n>=1, and MQ_n with at most n-2 elements is pancyclic for n>=2. Second, we show that an n-dimensional hypercube Q_n with at most 2n-5 non-free edges and at most 2n-4 faulty elements in which each node is incident to at least two free edges contains a fault-free cycle of length at least 2^n-2|F_v|. With the previous result, we further show that under the same fault condition, Q_n contains a fault-free cycle of every even length from 4 to 2^n-2|F_v|. For fault diagnosis, we evaluate that the conditional diagnosability of an n-dimensional augmented cube AQ_n under the PMC model is 8n-27 for n>=5.
