Abstract Glass fibre reinforced polymer composites are frequently used in marine applications where the combined effects of cyclic loads and seawater environment limit their fatigue life. This paper aims to demonstrate degradation that causes stiffness composites. Three-point bending properties cross-ply woven glass commonly manufacture tidal turbine blades reported for both wet dry conditions....

Software rejuvenation is a technique for software fault tolerance which involves occasionally stopping the executing software, \cleaning" the \internal state" and restarting. This cleanup is done at desirable times during execution on a preventive basis so that unplanned failures, which result in higher costs compared to planned stopping, are avoided. Since during rejuvenation, the software is ...

This paper proposes the use of machine learning techniques to make storage systems more reliable in the face of sector errors. Sector errors are partial drive failures, where individual sectors on a drive become unavailable, and occur at a high rate in both hard disk drives and solid state drives. The data in the affected sectors can only be recovered through redundancy in the system (e.g. anot...

The aye-aye is considered the most widely distributed lemur in Madagascar; however, the effect of forest quality on aye-aye abundance is unknown. We compared aye-aye presence across degraded and non-degraded forest at Ranomafana National Park, Madagascar. We used secondary signs (feeding sites, high activity sites) as indirect cues of aye-aye presence and Canarium trees as an indicator of resou...

Abstract Stretchable thermoelectric generators (S-TEGs) have the potential to utilize waste heat from sources with complex and dynamic surfaces. However, their performances are still lower than those of conventional hard rigid TEGs easily degraded by large or cyclic deformations due electrical failure. An approach that improves both stretchability performance is required. This study presents ex...

TiN/SiOx duplex coatings were synthesized on AISI304 stainless steel by plasma immersion ion implantation and deposition (PIIID) followed by radio frequency magnetron sputtering (RFMS). The microstructure and tribocorrosion failure behaviors of the duplex coatings were investigated by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, atomic force microscopy, rec...

As large parallel systems increase in size and complexity, failures are inevitable and exhibit complex space and time dynamics. Most often, in real systems, failure rates are increasing or decreasing over time. Considering non-memoryless failure distributions, we study a bi-objective scheduling problem of optimizing application makespan and reliability. In particular, we determine whether one c...

The landmark report by de Bold et al. in 1981 signified the heart as one of the endocrine organs involved in fluid and salt balance (de Bold AJ, Borenstein HB, Veress AT, Sonnenberg H. Life Sci 28: 89-94, 1981). Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are secreted from cardiomyocytes in response to cardiac stretch as in the case of heart failure, whereas C-type natr...

riverbank erosion, land loss and associated sedimentation are river engineering and water resources management problems of global significance. the ability to predict riverbank stability on eroding rivers is the prerequisite of developing a channel width adjustment model and is essential for estimating riverbank erosion and associated sedimentation. in this research, a detailed model for stabil...

Reliability is a fundamental requirement in electric propulsion systems, involving particular approach studies on system failure probabilities. An intrinsic improvement to the involves introducing robust architectures such as fault-tolerant motor drives these systems. Considering potential for hardware failures, design will achieve reliability objectives without recourse optimized redundancy or...
