Degradation analysis is used to analyze the useful lifetimes of systems, their failure rates, and various other system parameters like mean time to failure (MTTF), mean time between failures (MTBF), and the system failure rate (SFR). In many systems, certain possible parallel paths of execution that have greater chances of success are preferred over others. Thus we introduce here the concept of...

from the regional ocean modeling system (ROMS), has three one-way nested domains with the finest resolution of 1.6 km in the horizontal direction and 32 levels in the vertical direction. In present research, the tidal simulation of the system is validated against tide gauges, ADCP current observations, high-frequency radar surface-current observations, and compared with the output from two baro...

The efficacy of both frame-of-reference (FOR) instructions and a measure of within-person inconsistency in predicting grade point average was investigated. The IPIP Big Five personality questionnaire was given to 329 students with generic instructions and ‘at school’ FOR instructions. The Wonderlic Personnel Test was also administered. A measure of withinperson inconsistency was created based o...

Both collinear factorization theorem 1 and kT factorization theorem 2,3 are the fundamental tools of perturbative QCD (PQCD), where kT denotes parton transverse momenta. In these theorems the amplitude for an exclusive process can be calculated as an expansion of αs(Q) and Λ/Q with Q being a large momentum transfer and Λ a small hadronic scale. Similarly, in the heavy quark limit mb → ∞, mb bei...

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...

This paper reviews the current state of knowledge of the open waters of the San Francisco Estuary. This estuary is well known for the extent to which it has been altered through loss of wetlands, changes in hydrography, and the introduction of chemical and biological contaminants. It is also one of the most studied estuaries in the world, with much of the recent research effort aimed at support...
