The maintenance dataset provided by SunWater contains information about failed assets also known as components and their corresponding failure modes. Currently, extraction of this information from the dataset been conducted in a manual manner, which is very tedious, time consuming and cumbersome work. It is necessary to discover an automatic method to decide/extract the failure mode. This paper...
Objective: To present an EFMEA analysis using the example of a seafood organisation, including risk identification, in context potential negative impact on environment. Research Design & Methods: Methods used include case study with secondary data (documents), semi-structured interviews representative synthesis and logical reasoning. Findings: is very complex extended additional considerati...
FMEA has been used for several years and proved its efficiency for system’s risk analysis due to failures. Risk priority number found in FMEA is used to rank failure modes that may occur in a system. There are some guidelines in the literature to assign the values of FMEA components known as Severity, Occurrence and Detection. This paper propose a method to assign the value for occurrence in mo...
Prognostics methods are being developed to evaluate the reliability of a system in its actual life-cycle conditions, to estimate the times to failure and to mitigate system risks. A key requirement in any prognostics method is identification of the appropriate parameter(s), which, can be used to asses impending failure, if monitored. This paper presents a physics-of-failure based methodology, w...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
the purpose of the present study was to investigate the latent pattern underlying reading ability . some 272 male and female participants. english majors at the ba level , participated in the study. two valid tests were used in this study, the reading test developed exclusively for the purpose of this project and academic reading section of ielts. to investigate the possible latent underlying...
The goal of the FMECA (Failure Mode, Effects and Criticality Analysis) process is to determine the consequences that failures may have on the function of a complex system. In aeronautic industries, this process is very important and must comply with international standards. Today, most of the process is performed manually. This can be problematic, since, although the basic process is not diffic...
Introduction: The use of dental ceramics has increased due to their beauty and biocompatibility. The aim of this study was to evaluate the effect of hydrofluoric acid concentration and etching time on microtensile bond strength (μTBS) of the Enamic and Suprinity ceramics. Material & Methods: In this in vitro study, two hydrofluoric acid (HFA) concentrations of 5% (A) and 10% (B) were used at t...
The failure mode and effects analysis (FMEA) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. One important issue of FMEA is the determination of the risk priorities of failure modes. Risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. In this study, we applied...
