In this paper, we propose new scheduling algorithms to achieve fault security in multiprocessor systems. We consider scheduling of parallel programs represented by directed acyclic graphs with arbitrary computation and communication costs. A schedule is said to be 1-fault-secure if the system either produces correct output for a parallel program or it detects the presence of any single fault in...

Silos are strategical structures used to stockpile various types of granular materials. They highly vulnerable earthquake excitation and have been frequently reported fail at a higher rate than any other industrial structure. The seismic response silos within the near-fault region will suffer complex combination loadings due unique characteristics ground motions; which usually associated with l...

Many schemes are reported for shunt fault location estimation, but fault location estimation of series or open conductor faults has not been dealt with so far. The existing numerical relays only detect the open conductor (series) fault and give the indication of the faulty phase(s), but they are unable to locate the series fault. The repair crew needs to patrol the complete line to find the loc...

[1] We investigate seismicity near faults in the Southern California Earthquake Center Community Fault Model. We search for anomalously large events that might be signs of a characteristic earthquake distribution. We find that seismicity near major fault zones in Southern California is well modeled by a Gutenberg-Richter distribution, with no evidence of characteristic earthquakes within the re...

A new method for the design of robust fault reconstruction filters is introduced in this paper. The method is based on shaping the map from disturbance inputs to the fault estimation error through frequency weighting functions and formulating the problem as a robust observer design where the input-output error map is minimized by solving a set of matrix inequalities. A numerical example consist...

Z-shape faulted dipoles in deformed GaAs were investigated by using high resolution electron microscopy. There is no difference in the core structure of the a and b dislocations of stair-rod and 90 Shockley partials, nor in the dissociated stacking fault width. The central stacking fault is found to generate large local atomic displacements and exhibits a different structure from that of the in...

In this paper, we experimentally evaluate outlier detection methods, which detect data points that are far away from others in a data set, in terms of improving the prediction performance of fault-prone module detection models. In the experiment, we compared two outlier detection methods (MOA, LOFM) each applied to three wellknown fault-prone module detection models (LDA, LRA, CT). The result s...

Numerous algorithms have been provided for maintaining the topology of a ring network in a fault-free environment. But a simple, fast and effective fault-tolerant algorithm has been lacking in this field so far. In this report, we seek to address this problem and provide a detailed design to solve the problem in the general case. As our detailed analysis proves, our algorithms function very wel...

Immediately following the 1966 Parkfield earthquake a continuing program of fault displacement measurements was undertaken, and several types of instruments were installed in the fault zone to monitor ground motion. In the year subsequent to the earthquake a maximum of at least 20 cm of displacement occurred on a 30 km section of the San Andreas fault, which far exceeded the surfidal displaceme...

This paper presents and evaluates a methodology for the emulation of software faults in COTS components using software implemented fault injection (SWIFI) technology. ESFFI (Emulation of Software Faults by Fault Injection) leverages matured fault injection techniques, which have been used so far for the emulation of hardware faults, and adds new features that make possible the insertion of erro...
