Semi-empirical mass formula — In nuclear physics, the semi empirical mass formula (SEMF), sometimes also called Weizsäcker s formula, is a formula used to approximate the mass and various other properties of an atomic nucleus. As the name suggests, it is partially based on… … Wikipedia
Heckman correction — The Heckman correction (the two stage method, Heckman s lambda or the Heckit method) is any of a number of related statistical methods developed by James Heckman in 1976 through 1979 which allow the researcher to correct for selection bias.… … Wikipedia
Atmospheric correction — is the process of removing the effects of the atmosphere on the reflectance values of images taken by satellite or airborne sensors. [cite web |url=http://www.umiacs.umd.edu/research/GC/atmo/index.html |title=Atmospheric Correction… … Wikipedia
Dot gain — (also known as Tonal Value Increase) is a phenomenon in offset lithography and some other forms of printing which causes printed material to look darker than intended. It is caused by halftone dots growing in area between the original printing… … Wikipedia
Quantum chemistry composite methods — are ab initio post Hartree Fock methods in computational chemistry that aim for high accuracy by combining the results of several calculations. They combine methods with a high level of theory and a small basis set with methods that employ lower… … Wikipedia
Carl Reinhold August Wunderlich — (1815 1877) was a German physician, pioneer psychiatrist, and medical professor. He is known for his measurement of mean healthy human body temperature of 37°C (98.6°F), now known more accurately to be about 36.8°C (98.2°F). [Cite journal doi =… … Wikipedia
Rietveld refinement — is a technique devised by Hugo Rietveld for use in the characterisation of crystalline materials. The neutron and x ray diffraction of powder samples results in a pattern characterised by peaks in intensity at certain positions. The height, width … Wikipedia
Crystal (software) — For other uses, see Crystal (disambiguation). CRYSTAL is a quantum chemistry ab initio program, designed primarily for calculations on crystals (3 dimensions), slabs (2 dimensions) and polymers (1 dimension) using translational symmetry, but it… … Wikipedia
Spectral signature — Spectral signatures are the specific combination of reflected and absorbed electromagnetic radiation at varying wavelengths which can uniquely identify an object. The spectral signature of an object is a function of 1) incidental EM wavelength… … Wikipedia
Brix — For other uses, see Brix (disambiguation). Degrees Brix (symbol °Bx) is the sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by weight (% … Wikipedia
Propensity score matching — In statistics, propensity score matching (PSM) is one of quasi empirical “correction strategies” that corrects for the selection biases in making estimates. Overview PSM is for cases of causal inference and simple selection bias in non… … Wikipedia
