Utilizing the gathered failure data and failure interval data from Tabas coal mine in two years, this paper discusses the reliability of powered supports. The data sets were investigated using statistical procedures and in two levels: the existence of trend and serial correlation. The results show that the powered supports follow the Gamma reliability function. The reliability of the machine de...

Many studies have explored the value of using more sophisticated coastal impact models and higher resolution elevation data in sea-level rise (SLR) adaptation planning. However, we know little about to what extent the improved models and data could actually lead to better conservation outcomes under SLR. This is important to know because high-resolution data are likely to not be available in so...

Objective: To describe the elaboration and content validity stages of a digital educational technology for nursing professionals about Japanese bathtub (ofurô) in newborns neonatal care units. Method: A methodological study conducted between August 2019 July 2021, public maternity hospital Manaus, Amazonas, developed two stages. In first, e-book images, text editing were produced. second, mater...

SUMMARY Nonparametric Bayesian inference using bathtub hazard rates in survival analysis is developed. A new simulation method, Auxiliary Random Functions, is introduced. When used within a Gibbs sampler, this method enables a uniied treatment of exact, right-censored, left-censored, left-trucated and interval censored data, with and without covariates. The models and methods are exempliied via...

For performance evaluation and dimensioning of packet-based networks, engineers need simple, efficient and realistic traffic models. The traffic volume on a packet link, observed at different time scales t, has previously been modeled as a stationary stochastic process based on the Coefficient of Variation CoV(t). In this paper we try to supply the missing information about the shape of the dis...

background: we aimed to analyze the effect of nursing strategies on patients with chronic renal failure (crf) undergoing maintenance hemodialysis (mhd) treatment by puncturing on arteriovenous fistula (avf). methods: ninety-two patients with chronic renal failure undergoing maintenance hemodialysis (mhd) between jan 2014 and jan 2015 were included in the study (all undergoing avf, dialysis for ...
