a critical value below which
1Critical mass — This article is about nuclear fission reactions. For other uses, see Critical mass (disambiguation). As part of a re creation of a 1945 criticality accident, a plutonium pit is surrounded by blocks of neutron reflective tungsten carbide. The… …
2Critical phenomena — In physics, critical phenomena is the collective name associated with the physics of critical points. Most of them stem from the divergence of the correlation length, but also the dynamics slows down. Critical phenomena include scaling relations… …
3Critical load — In the study of air pollution, a critical load is defined as ”A quantitative estimate of an exposure to one or more pollutants below which significant harmful effects on specified sensitive elements of the environment do not occur according to… …
4Critical exponent — Critical exponents describe the behaviour of physical quantities near continuous phase transitions. It is believed, though not proven, that they are universal, i.e. they do not depend on the details of the physical system, but only on the… …
5Value network analysis — is a methodology for understanding, using, visualizing, optimizing internal and external value networks and complex economic ecosystems. The methods include visualizing sets of relationships from a dynamic whole systems perspective. Robust… …
6Critical minimum effort theory — The critical minimum effort theory has been given by Harvey Leibenstein, in his book Economic Backwardness and Economic Growth. This theory relates to overpopulated and underdeveloped or developing nations such as India and Indonesia.This theory… …
7Critical dimension — For the minimum feature size in photolithography, see Photolithography. In the renormalization group analysis of phase transitions in physics, a critical dimension is the dimensionality of space at which the character of the phase transition… …
8Critical band — The term critical band, introduced by Harvey Fletcher in the 1940s, referred to the frequency bandwidth of the then loosely defined auditory filter. Psychophysiologically, beating and auditory roughness sensations can be linked to the inability… …
9Critical bands — The term critical band, introduced by Harvey Fletcher in the 1940s, referred to the frequency bandwidth of the then loosely defined auditory filter. Since Georg von Békésy’s studies (1960), the term also refers literally to the specific area on… …
10Critical period hypothesis — The critical period hypothesis is the subject of a long standing debate in linguistics and language acquisition over the extent to which the ability to acquire language is biologically linked to age. The hypothesis claims that there is an ideal… …
