A new framework for the implementation of reliability centered maintenance (RCM) in the initial design phases of industrial chemical processes was developed and implemented. Fuzzy reasoning algorithms were designed to evaluate and assess the likelihood of equipment failure mode precipitation and aggravation. Furthermore, an approximate reasoning scheme which considers local, product, and adjace...
Dear editor In a recent issue of the journal, Dastani et al. (2019) evaluate the effects of curcumin on the prevention of atrial and ventricular arrhythmias and heart failure in patients with unstable angina. Despite the fact that the topic was interesting, there were some defects and we wish to call to your attention important factual issues in this publication. The most cr...
The reliability study is the most important part of engineering design process, as it basis analysis and assessment future product performance in exploitation. Since cannot be predicted with absolute certainty, application theory includes probability unreliability modeling. proposed approach has been applied to assess gear planetary power transmissions. system was determined on block diagram me...
I address practical issues concerning the construction of normative expert systems, and examine the influence diagram as a potential framework for representing knowledge in such systems. I introduce an extension of the influence-diagram representation called a similarity network. A similarity network is a tool for constructing large and complex influence diagrams. The representation allows a us...
Risk analysis of production system, while the actual and appropriate data is not available, will cause wrong system parameters prediction and wrong decision making. In uncertainty condition, there are no appropriate measures for decision making. In epistemic uncertainty, we are confronted by the lack of data. Therefore, in calculating the system risk, we encounter vagueness that we have to use ...
abstract the current study set out to address the issue as to whether the implementation of portfolio assessment would give rise to iranian pre-intermediate efl learner autonomy. participants comprised 60 female in pre-intermediate level within the age range of 16-28.they were selected from among 90 language learners based on their scores on language proficiency test -key english test. then, t...
• Analysis of the static assessment thin and flawed AM parts made AlSi10Mg; Even if material is quasi brittle, fracture has to consider elasto-plastic behaviour. Flaw based on FAD adequate it allows obtain simple Limit Load Diagrams for determining acceptable flaws. Several factors must be considered within produced by Additive Manufacturing (AM) such as, example, heterogeneous microstructure, ...
امروزه یکی از مباحث مطرح در بحث امنیت سیستم های اطلاعاتی امکان یکپارچگی امنیت در پروسه طراحی و پیاده سازی این سیستم ها می باشد. زیرا پرداختن به مقوله امنیت در ایجاد سیستم ها به طور منزوی نمی تواند کارایی لازم در برآورد کردن نیازهای امنیتی را داشته باشد. یکی از اجزای مهم سیستم های اطلاعاتی پایگاه های داده می باشند که در بحث یکپارچگی امنیت و طراحی کمتر به آنها پرداخته شده است. در این پژوهش با توج...
Using finite element nonlinear analysis, the dynamic soil pressure on perimeter retainingwalls of structures is investigated. Nonlinear Drucker Prager failure criterion is used to model the soilbehavior in the near field. The far field soil and the middle structure are assumed to behave as linearelastic materials. The soil-wall interface behavior is modeled incorporating nonlinear interfaceelem...
The corner stone of a language development environment is an editor. For programming languages, several code editors are readily available to be integrated in Web applications. However, only few editors exist for diagrammatic languages. Eshu is an extensible diagram editor, embeddable in Web applications that require diagram interaction, such as modeling tools or e-learning environments. Eshu i...
