Critical infrastructure protection requires the evaluation of the criticality of infrastructures and the prioritization of critical assets. However, criticality analysis is not yet standardized. This paper examines the relation between risk and criticality. It analyzes the similarities and differences in terms of scope, aims, impact, threats and vulnerabilities; and proposes a generic risk-base...

The paper is concerned with the study of criticality analysis of components of Gas Turbine Power Plant Systems (GTPPS) and the failures occurring in the plant. Failure mode and effect and criticality analysis (FMECA) is carried out to estimate the criticality number for different components and failure modes. In addition the failure effects, higher effects and end effects are incorporated in th...

Dammarane-type saponins (DTSs) exist in various medicinal plants, which are a class of active ingredients with effects on improving myocardial ischemia and immunomodulation. In this study, quantitative 1H NMR method total DTSs herbal medicines was developed based the analytical procedure lifecycle. first stage (analytical design), Ishikawa diagram failure mode criticality analysis were used to ...

Does the brain operate at criticality, to optimize neural computation? Literature uses different fingerprints of criticality in neural networks, leaving the relationship between them mostly unclear. Here, we compare two specific signatures of criticality, and ask whether they refer to observables at the same critical point, or to two differing phase transitions. Using a recurrent spiking neural...

in this research, shielding and criticality safety calculations carried out for interim storage and transportation cask in the tehran research reactor. such dual purpose cask is being designed to the spent fuel elements of research reactors. the monte carlo mcnp5 code calculation was utilized for the criticality safety analysis and origen2.1code was used for shielding calculation. according to ...

The neural criticality hypothesis states that the brain may be poised in a critical state at a boundary between different types of dynamics. Theoretical and experimental studies show that critical systems often exhibit optimal computational properties, suggesting the possibility that criticality has been evolutionarily selected as a useful trait for our nervous system. Evidence for criticality ...

Ideally, mixed criticality systems should allow architects to consolidate separately certified tasks with differing safety requirements into a single system. Consolidated, they are able to share resources (even across criticality levels) and reduce the system’s size, weight and power demand. To achieve this, higher criticality tasks are also subjected to the analysis methods suitable for lower ...

Critical Infrastructure Protection requires the prioritization of critical assets and the evaluation of the criticality of infrastructures. However, criticality analysis is not yet standardized. In this paper we examine the relation between security risk and criticality. We analyze the similarities and differences in terms of scope, aims, impacts, threats and vulnerabilities and we suggest how ...

Scheduling isolation in mixed-criticality systems is challenging without sacrificing performance. In response, we propose a scheduling approach that combines server-based semi-partitioning and deadline scaling. Semipartitioning (whereby only some tasks migrate, in a carefully managed manner), hitherto used in single criticality systems, offers good performance with low overheads. Deadline-scali...
