Background: Cognitive failure is mental lapses in perception, attention, memory, and action. It occurs during routine tasks that one would usually have no difficulty in successfully completing. Cognitive performance is influenced by conditions and some individual and job characteristics and the identification of factors that affect human performance is essential to prevent human error. The purp...

This paper deals with the Reliability analysis of K-out-of-n : G redundant system in the presence of Lethal & Non-lethal Common Cause Shock failures (CCS) along with imperfect fault coverage. S.Akhtar (1994) has discussed the reliability analysis of k-out-of-n: G redundant system with Perfect and imperfect fault coverage and derived Reliability measures namely Rs (t), As (t), MTTF, MTBF. K.Mall...

Abstract In a Bayesian framework, the Dirichlet distribution is the conjugate distribution to the multinomial likelihood function, and so the analyst is required to develop a Dirichlet prior that incorporates available information. However, as it is a multiparameter distribution, choosing the Dirichlet parameters is less straightforward than choosing a prior distribution for a single parameter,...

Data processing frameworks like Hadoop need to efficiently address failures, which are common occurrences in today’s large-scale data center environments. Failures have a detrimental effect on the interactions between the framework’s processes. Unfortunately, certain adverse but temporary conditions such as network or machine overload can have a similar effect. Treating this effect oblivious to...
