Numerous methods have been proposed to automatically extract fault surfaces from 3D seismic images, and those surfaces are often represented by meshes of triangles or quadrilaterals. However, extraction of intersecting faults is still a difficult problem that is not well addressed. Moreover, mesh data structures are more complex than the arrays used to represent seismic images, and they are mor...

The failure-prone complex operating environment of a standard multi-robot application dictates some amount of fault-tolerance to be incorporated into the system. Being able to identify the extent of fault-tolerance in a system would be a useful analysis tool for the designer. Unfortunately, it is difficult to quantify system fault-tolerance on its own. A more tangible metric for evaluation is t...

Measuring the steady state leakage current (IDDQ) is a very successful testing paradigm detecting faults not discovered when considering standard fault models. Due to increasing vector dependencies and process variations IDDQ testing becomes more difficult. We propose ATPG algorithms to control test vector dependencies even before performing the IDDQ test. Experimental results show that leakage...

the nw-se trending tus fault is one of the active faults in the north-east of iran . geomorphologic evidences indicate that this fault is active and goes through mashhad city from near tus town. since the population and number of pilgrims in this city are high, the study of the tus fault is of great importance. hence, we have carried out a new investigation to evaluate the hazardous potential o...

We present a new software architecture in which all concepts necessary to achieve fault tolerance can be added to an application automatically without any source code changes. As a case study, we consider the problem of providing a reliable service despite node failures by executing a group of replicat-ed servers. Replica creation and management as well as failure detection and recovery are per...

an attempt has been made to explore the general trends in the seismic response of planasymmetric structures when subjected to near-fault and far-fault ground motions. systems with structural wall elements in both orthogonal directions considering actual and common nonlinear behavior under bi-directional excitation were studied. idealized single-storey models with uni-axial eccentricity were emp...

Designing applications with timeliness requirements in environments of uncertain synchrony is known to be a difficult problem. In this paper, we follow the perspective of timing fault tolerance: timing errors occur, and they are processed using redundancy, e.g., component replication, to recover and deliver timely service. We introduce a paradigm for generic timing fault tolerance with replicat...

superconductor fault current limiter (sfcl) is an effective device to suppress high fault currents. this paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  appropriate location and type of the limiters in a hv substation is selected by a qualitative approach based on the equal area criterion. study system is simulated by...
