51Luminosity function — The luminosity function or luminous efficiency function describes the average sensitivity of the human eye to light of different wavelengths. It should not be considered perfectly accurate in every case, but it is a very good representation of… …
52Classified information in the United States — For information on practices in other countries, see Classified information. The United States government classification system is currently established under Executive Order 13526, the latest in a long series of executive orders on the topic.[1] …
53Radiocarbon dating — (sometimes simply known as carbon dating) is a radiometric dating method that uses the naturally occurring radioisotope carbon 14 (14C) to estimate the age of carbon bearing materials up to about 58,000 to 62,000 years.[1] Raw, i.e. uncalibrated …
54Bisulfite sequencing — Figure 1: Outline of bisulfite conversion of sample sequence of genomic DNA. Nucleotides in blue are unmethylated cytosines converted to uracils by bisulfite, while red nucleotides are 5 methylcytosines resistant to conversion …
55dating — I In geology and archaeology, the process of determining an object s or event s place within a chronological scheme. Scientists may use either relative dating, in which items are sequenced on the basis of stratigraphic clues (see stratigraphy) or …
56Metamerism (color) — This article is about metamerism as it relates to colorimetry. For other meanings see the disambiguation page. In colorimetry, metamerism is the matching of apparent color of objects with different spectral power distributions. Colors that match… …
57Price discrimination — or price differentiation[1] exists when sales of identical goods or services are transacted at different prices from the same provider.[2] In a theoretical market with perfect information, perfect substitutes, and no transaction costs or… …
58Break even analysis — The break even point for a product is the point where total revenue received equals the total costs associated with the sale of the product (TR=TC). [Horngren, C.,Sundem, G Stratton, W. Introduction to Management Accounting (2002) Prentice Hall]… …
59Diagnostic odds ratio — log(Diagnostic Odds Ratio) for varying sensitivity and specificity The diagnostic odds ratio is a measure of the effectiveness of a diagnostic test.[1] It is defined as the ratio of the odds of the test being positive if the subject has a disease …
60Nanoindentation — is a variety of indentation hardness tests applied to small volumes. Indentation is perhaps the most commonly applied means of testing the mechanical properties of materials. The nanoindentation technique was developed in the mid 1970s to measure …
