- The range of light intensities, from 105 lux down to nearly 10-2 lux, detectable by the human eye.
- Vision which is adapted to bright light such as daylight, using the cones in the retina instead of the rods, which are used in scotopic vision. light adaptation
- Average spectral responsivity curve of the human eye when adapted to well lit conditions (greater than 0.034 cd·m–2). the photopic spectral luminous efficiency response curve is governed by an averaged retinal cone response with sensitivity peaks centered at about 555 nm. also known as foveal vision and light adapted vision. compare mesopic vision and scotopic vision.2,6

Adaptation, английский
- Адаптация; самонастройка; самоприспосабливание
- Адаптация (приспособление организма к изменившимся условиям среды, питательным и токсичным веществам)
- 1. a change which has been or can be made to something 2. the act of changing something so that it fits a new situation 3. the process by which sensory receptors become accustomed to a sensation which is repeated add add abbr attention deficit disorder
- Адаптация
- N адаптация14 (тж. adaption, см. тж. adoption) theory
- Адаптация; приспособление
- 1) characteristics of organisms evolved as a consequence of natural selection; 2) changes in the form or behavior of an organism during life as a response to environmental stimuli; 3) changes in the excitability of a sense organ as a result of continuos stimulation.
- Stability of success in the face of a changing environment. two kinds of adaptation are distinguished. (a) darwinian adaptation after darwin who observed how organisms change their internal structure when their environment makes existing forms no longer viable. e.g., ashby`s homeostat searches for a new pattern of behavior as soon as disturbances in its surroundings drive or threaten to drive its essential variables outside specified limits. (b) singerian adaptation after singer who described how organisms, particularly man, change the nature of their environment so as to eliminate threats to or prevent the destruction of their own internal organization. e.g., agriculture, architecture and technology adapt the physical environment to human-social needs. the difference between "adaptive" and "adapting" behavior (steg) also reflects this distinction. adaptation can occur in several levels of an organiz~tional hierarchy and may even apply to itself as in "amplifying adaptation" (ashby) which is "adaptation to adapt" and has the properties of self-organization.
- Initiatives and measures to reduce the vulnerability or increase the resilience of natural and human systems to actual or expected climate change impacts. various types of adaptation exist, for example, anticipatory and reactive, private and public, and autonomous and planned. examples are raising river or coastal dikes, retreating from coastal areas subject to fl ooding from sea level rise or introducing alternative temperature-appropriate or drought-adapted crops for conventional ones.

- The sensitivity of classification rule is a measure of its ability to correctly classify observations into a particular category. it is defined to be the ratio of the number of true positives to the number of positives in a test set. this value is usually inversely related to the specificity of the test for a given set of data and a particular classification rule. note that this measure is different from the positive predictive value of a rule, which is a measure of the probability that a positive is a true positive. if multiple classification categories exist, each category will have its own sensitivity, specificity, and positive predictive value. see also: positive predictive value, specificity.
