Faults are the most critical tectonic factors in geological structures, which have major economic impacts on mining economics. Thus it is necessary to understand faults in order to identify the actual risks and complications associated with mining. In the preliminary investigation of the Sonda-Jherruck coalfield, 3D geological modeling was not performed. The purpose of this work was to perform ...

The goal of this work is to present some theoretical results which can be used for increasing fault sensitivity of a detection scheme, without sacrificing robustness. Robustness against modeling uncertainties and fault sensitivity are two contradicting demands, and typically, one is achieved at the expense of the other. The main reason for this trade-off is the use of a worst case scenario boun...

Abstract The magnitude of earthquakes on continental normal faults rarely exceeds 7.0 Mw. However, because their vicinity to large population centers they can be highly destructive. Long recurrence time, relatively small deformations, and limited observations hinder our understanding the deformation patterns mechanisms controlling events. Here, this problem is addressed with 2D thermomechanical...

The proposed fault diagnosis approach associates an adaptive observer for residual generation with set-membership computations based on zonotopes for residual evaluation. The main advantage of this approach is its rigorous propagation of pre-specified modeling uncertainty bounds to the computed residuals. Within the assumed modeling uncertainty bounds, fault detection is guaranteed to be free o...

This research introduces a new approach to modeling wireless network reliability under diverse fault assumptions. It allows for quantifying reliability and offers potential for modeling survivability. The general model is presented as a join graph of cliques, that allows for horizontal and orthogonal cross-monitoring. This allows for the determination of the maximal potential fault tolerance. T...

Real time and accurate fault detection has attracted an increasing attention with a growing demand for higher operational efficiency and safety of industrial gas turbines as complex engineering systems. Current methods based on condition monitoring data have drawbacks in using both expert knowledge and quantitative information for detecting faults. On account of this reason, this paper proposes...

Software product line engineering is a proposed methodology that enables software products and software-intensive systems to be developed at lower cost, higher quality and less time to market. The structured and managed artifacts reuse among di erent products in development is the main target of software product line engineering. As a key-method of the product line engineering approach, the com...
