P-completeIn computational complexity theory, a decision problem is P-complete (complete for the complexity class P) if it is in P and every problem in P can be reduced to it by an appropriate reduction. The notion of P-complete decision problems is useful in the analysis of: which problems are difficult to parallelize effectively, which problems are difficult to solve in limited space. specifically when stronger notions of reducibility than polytime-reducibility are considered.
Linear discriminant analysisLinear discriminant analysis (LDA), normal discriminant analysis (NDA), or discriminant function analysis is a generalization of Fisher's linear discriminant, a method used in statistics and other fields, to find a linear combination of features that characterizes or separates two or more classes of objects or events. The resulting combination may be used as a linear classifier, or, more commonly, for dimensionality reduction before later classification.
Genesis flood narrativeThe Genesis flood narrative (chapters 6–9 of the Book of Genesis) is a Hebrew flood myth. It tells of God's decision to return the universe to its pre-creation state of watery chaos and remake it through the microcosm of Noah's ark. The Book of Genesis was probably composed around the 5th century BCE, although some scholars believe that Primeval history (chapters 1–11), including the flood narrative, may have been composed and added as late as the 3rd century BCE.
Interventionism (politics)Interventionism is a political practice of intervention, particularly to the practice of governments to interfere in political affairs of other countries, staging military or trade interventions. Economic interventionism is a different practice of intervention, one of economic policy at home. Military intervention, as the main issue, has been defined by Martha Finnemore in the context of international relations as "the deployment of military personnel across recognized boundaries for the purpose of determining the political authority structure in the target state".
Water extractionWater extraction (or water withdrawal) is the process of taking water from any source, either temporarily or permanently, for flood control or to obtain water for, for example, irrigation. The extracted water could also be used as drinking water after suitable treatment. Depending on the environmental legislation in the country, controls may be placed on extraction to limit the amount of water that can be removed. The over-extraction of water can lead to dry rivers or declining groundwater levels.
Flood geologyFlood geology (also creation geology or diluvial geology) is a pseudoscientific attempt to interpret and reconcile geological features of the Earth in accordance with a literal belief in the Genesis flood narrative, the flood myth in the Hebrew Bible. In the early 19th century, diluvial geologists hypothesized that specific surface features provided evidence of a worldwide flood which had followed earlier geological eras; after further investigation they agreed that these features resulted from local floods or from glaciers.
