Machine fault diagnostic and prognostic techniques have been the considerable subjects of condition-based maintenance system in the recent time due to the potential advantages that could be gained from reducing downtime, decreasing maintenance costs, and increasing machine availability. For the past few years, research on machine fault diagnosis and prognosis has been developing rapidly. These ...
Synchronizer circuits are usually characterized by their rate of failure in transmitting data between two independently timed regions. The mean time between failures is assumed to be MTBF e T f f t

This article presents a new approach for system-level reliability management technique for multi-core microprocessors. In the new approach, the electromigration (EM) induced mean time to failure (MTTF) at the system level is modeled as a resource, which is abstracted from a more physics-based EM model. Based on such resource-based EM models, we propose a novel task migration method to explicitl...
When P2P systems are used for data sensitive systems, the data availability has become an important issue. The availabilitybased replication using individual node availability is the most popular method keeping high data availability efficiently. However, since the individual node availability is derived by the individual lifetime information of each node, the availability-based replication may...
Network failure detection techniques and link Mean Time Between Failure (MTBF) estimates are required to assess the reliability of large communication networks. We present an experience based on utilization logs from a large ISP network comprising hundreds of links, and spreading over a geographic area. The complexity of the network requires accounting also for the mutual dependencies between e...
Five different algorithms for cooperation between assembly/packaging robots in a distributed system were developed and evaluated in simulation. Independent, autonomous operation of each robot was assumed. The goal was to maximize the number of assemblies while minimizing the standard deviation of the work between the different robots. Two of the algorithms, a fuzzy algorithm and a simple “take-...
This paper addresses the problem of scheduling non-preemptive moldable tasks to minimize the stretch of the tasks in an online non-clairvoyant setting. To the best of the authors’ knowledge, this problem has never been studied before. To tackle this problem, first the sequential sub-problem is studied through the lens of the approximation theory. An algorithm, called DASEDF, is proposed and, th...
Based on our current expectation for the exascale systems, composed of hundred of thousands of many-core nodes, the mean time between failures will become small, even under the most optimistic assumptions. One of the most scalable checkpoint restart techniques, the message logging approach, is the most challenged when the number of cores per node increases, due to the high overhead of saving th...
This paper presents the reliability and mean time to failure estimation of a deteriorating system that deteriorates with time. The system is two unit active parallel system where the units operates simultaneously. In this study maintenance is not allowed to the system. Laplace transforms is being utilize to solve the mathematical model developed. Expressions for reliability and Mean time to fai...
