In mathematics, in the realm of group theory, a group is said to be critical if it is not in the variety generated by all its proper subquotients, which includes all its subgroups and all its quotients. [1] Any finite monolithic A-group is critical. This result is due to Kovacs and Newman. [2] But not every monolithic group is critical. [3]
Structured criticality is a property of complex systems in which small events may trigger larger events due to subtle interdependencies between elements. This often gives rise to a form of stratified chaos where the general behavior of the system can be modeled on one scale while smaller- and larger-scale behaviors remain unpredictable.
Criticality (status), a milestone in the commissioning of a nuclear power plant; Criticality accident, an uncontrolled nuclear chain reaction; Nuclear criticality safety, the prevention of nuclear and radiation accidents resulting from an inadvertent, self-sustaining nuclear chain reaction; Prompt critical, an assembly for each nuclear fission ...
The group formed by the recurrent configurations, as well as the group / ′ to which the former is isomorphic, is most commonly referred to as the sandpile group. Other common names for the same group are critical group, Jacobian group or (less often) Picard group.
Critical consciousness, conscientization, or conscientização in Portuguese (Portuguese pronunciation: [kõsjẽtʃizaˈsɐ̃w]), is a popular education and social concept developed by Brazilian pedagogue and educational theorist Paulo Freire, grounded in neo-Marxist critical theory. Critical consciousness focuses on achieving an in-depth ...
The critical point is described by a conformal field theory. According to the renormalization group theory, the defining property of criticality is that the characteristic length scale of the structure of the physical system, also known as the correlation length ξ, becomes infinite. This can happen along critical lines in phase space.
The Criticality Index allows you to identify tasks that are likely to cause delays to the project. [1] [2] By monitoring tasks with a high Criticality Index a project is less likely to be late. If a task has a 100% Criticality Index it means that during the analysis no matter how the task durations varied, the critical path always included the ...
Criticality is the normal operating condition of a nuclear reactor, in which nuclear fuel sustains a fission chain reaction.A reactor achieves criticality (and is said to be critical) when each fission releases a sufficient number of neutrons to sustain an ongoing series of nuclear reactions.
