The rock masses in a construction site of underground cavern are generally not continuous, due to the presence of discontinuities, such as bedding, joints, faults, and fractures. The performance of an underground cavern is principally ruled by the mechanical behaviors of the discontinuities in the vicinity of the cavern. During underground excavation, many surrounding rock failures have close r...

The probability of faults, and especially transient faults, occurring in the field is increasing with the evolutions of the CMOS technologies. It becomes therefore crucial to predict the potential consequences of such faults on the applications. Fault injection techniques based on the high level descriptions of the circuits have been proposed for an early dependability analysis. In this paper, ...

The stress-and-strain state of the rock massif and kinematic type faults Vuoksi fault zone (Karelian Isthmus) for latest stage tectonic history were determined by field tectonophysical methods. main information was obtained from geological stress/strain indicators, which mostly represented measurements minor slickensides with (the direction relative displacement) on plane. Near zone, systems an...

Diagnosis of intermittent faults is significantly different from diagnosis of permanent faults, especially when selecting one or several preferred diagnoses. In this paper, we describe a new modeling approach for intermittent faults based on Past Time Linear Temporal Logic (PTLTL), and we suggest a conditional diagnosis selection approach based on Conditional Preference theories. We describe ho...

In this paper, a novel methodology for test preparation of digital ICs, aiming at high defect coverage and affordable computational eeort, is proposed. A method is presented to heuristically generate a list of pseudo realistic (PSE) faults, at gate level, such that test quality is improved when PSE faults are used in test generation , in addition to normal stuck-at testing. Test quality assessm...

Deformation pattern of the northeastern part of the Iranian-Arabian collision zone (i.e., mainly Sanandaj-Sirjan Belt or Zone) is the main concern of this paper. Here, we investigate the stress distribution and displacement pattern of Eghlid-Deh Bid area as affected by the position of Zagros suture using a three dimensional mechanical model. The modeled area is located between the Zagros Thrust...

In this study an observer-based novel design of robust control system with an estimate scheme of sensor states to accommodate extended bounded-sensor faults is proposed. The sensor faults are, in general, modeled as polytopic bounds in robust control framework and are usually given as a priori assumption. But, in practice, the sensors that are subject to faults are especially vulnerable to vari...

One of the remarkable tectonic features of the Earth’s crust is the widespread presence of long, approximately straight and geomorphically prominent strike-slip faults which are a kinematic consequence of large-scale motion of plates on a sphere (Wilson 1965). Strike-slip faults form in continental and oceanic transform plate boundaries; in intraplate settings as a continental interior response...
