Computational Grids have the potential to become the main execution platform for high performance and distributed applications. However, such systems are extremely complex and prone to failures. In this paper, we present a survey with the grid community on which several people shared their actual experience regarding fault treatment. The survey reveals that, nowadays, users have to be highly in...

INTRODUCTION Cognitive failures are errors in normal everyday functioning. Individuals with psychological disorders may possess heightened vulnerability. We sought to review the literature on cognitive failures in psychological disorders to determine the nature of this association, and whether failures relate to neuropsychological performance. We also examine the relationship between cognitive ...

greater levels of complexity in tunnelling with tunnel boring machine (tbm) allow higher chances of failures that may increase the potential hazardous risks. this paper presents the results of a study on tbm reliability using risk analysis. machinery failure mode and effect analysis was applied to analyze the risks of a tbm using qs9000 and sae.j1739 recommendations. for this purpose, 48 failur...

background: the reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. defect and failure in one part of a system can cause total system breakdown or accident. the failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. the purp...

BACKGROUND AND OBJECTIVES The impact of AKI on adverse drug events and therapeutic failures and the medication errors leading to these events have not been well described. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A single-center observational study of 396 hospitalized patients with a minimum 0.5 mg/dl change in serum creatinine who were prescribed a nephrotoxic or renally eliminated medi...

The lifetime of micro electro–thermo–mechanical actuators with complex electro–thermo–mechanical coupling mechanisms can be decreased significantly due to unexpected failure events. Even more serious is the fact that various failures are tightly coupled due to micro-size and multi-physics effects. Interrelation between performance and potential failures should be established to predict reliabil...

Health care failure modes and effects analysis (FMEA) is a widely used technique for assessing risk of patient injury by prospectively identifying and prioritizing potential system failures. In this study, we conducted in situ simulations at a major suburban hospital as a novel method to discover latent conditions and active failures and to prioritize these based on the potential severity of ri...

Electrical power grid contingency analysis aims to understand the impact of potential component failures and assess a system’s capability to tolerate them. The computational resources needed to explore all potential x-component failures, for modest sizes of x > 1, is not feasible due to the combinatorial explosion of cases to consider. A common approach for addressing the large workload is to s...
