If sufficient historical failure life data exist, the distribution of system can be estimated to identify initial hazard function. The conventional proportional covariate model (PCM) reveal dynamic relationship between response covariates and rate. rate function constantly updated by through basic (BCF). Under circumstances sparse or zero data, key point PCM reliability assessment method is det...

In Wireless Sensor Networks (WSNs), reliable and rapid neighbour node discovery is considered as the crucial operation which frequently needs to be executed over entire lifecycle. Several mechanisms are proposed for reducing latency or extending sensor nodes’ lifetime. But majority of existing failed in addressing critical issues real WSNs related energy consumptions, constraints latency, uncer...

This paper aims to develop a hierarchical risk assessment model using the newlydeveloped evidential reasoning (ER) rule, which constitutes a generic conjunctive probabilistic reasoning process. In this paper, we first provide a brief introduction to the basics of the ER rule and emphasize the strengths for representing and aggregating uncertain information from multiple experts and sources. Fur...

‎Selecting the most suitable robot among their wide range of specifications and capabilities is an important issue to perform the hazardous and repetitive jobs‎. ‎Companies should take into consideration powerful group decision-making (GDM) methods to evaluate the candidates or potential robots versus the selected attributes (criteria)‎. ‎In this study‎, ‎a new GDM method is proposed by utilizi...

An investigation was made on composites containing AA6082 as matrix and boron nitride/molybdenum disulphide (BN/MoS2) reinforcement, which a composite materials hybrid at 3 wt% of BN 1% MoS2 fabricated by stir casting methodology. Using electrical discharge machining (EDM) equipment, machinability studies were undertaken to achieve an optimal condition process parameters. Taguchi (L27 orthogona...

Federal law prohibits discrimination in employment decisions against persons in certain protected categories. The common method for measuring discrimination involves a comparison of some aggregate statistic for protected and non-protected individuals. This approach is open to question when employment decisions are made over an extended time period. We show how to use hierarchical proportional h...

This work links optimization approaches from hierarchical least-squares programming to instantaneous prioritized whole-body robot control. Concretely, we formulate the Newton’s method which solves nonlinear problems in a numerically stable fashion even presence of kinematic and algorithmic singularities approximated constraints. These results are then transferred control exhibit additional vari...

in this article differential transformation method (dtms) has been used to solve neutral functional-differential equations with proportional delays. the method can simply be applied to many linear and nonlinear problems and is capable of reducing the size of computational work while still providing the series solution with fast convergence rate. exact solutions can also be obtained from the kno...

this study aimed at investigating the reliability, predictive validity, and self-esteem and gender bias of confidence-based scoring. this is a method of scoring in which the test takers receive a positive or negative point based on their rating of their confidence in an answer. the participants, who were 49 english-major students taking their grammar course, were given 8 multiple-choice tests d...
