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...

‎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...

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...

Information and communication technology (ICT) enable information to be accessed processed through all kinds of visual, audio, printed written tools. This study aimed evaluate the ICT development G7 countries by using Multi Criteria Decision Making (MCDM) methods. Accordingly, Entropy method was used specify criteria weights, Proximity Indexed Value (PIV), Range (ROV), COmplex PRoportional ASse...

With the increasing risk to human health and environmental issues, selection of appropriate management treatment healthcare waste has become a major problem, especially in developing countries. There are various alternatives dispose care waste. The important is assess best alternative among them. assessment each should be done based on public health, psychological, economic, environmental, tech...
