In 1991, John McCumber created a model framework for establishing and evaluating information security (information assurance) programs, now known as The McCumber Cube. This security model is depicted as a three-dimensional Rubik's Cube-like grid. The concept of this model is that, in developing information assurance systems… WebThe McCumber relation [1] [2] expresses the emission cross-seccion in terms of the absorption cross-section : where is temperature, is Boltzmann constant and is zero-line …

It is named after Dean McCumber, who proposed the relationship in 1964. Meer weergeven It is typical that the lasing properties of a medium are determined by the temperature and the population at the excited laser level, and are not sensitive to the method of excitation used to achieve it. In this case, … Meer weergeven Consider the set of active centers (fig.1.). Assume fast transition between sublevels within each level, and slow transition between … Meer weergeven In the case of an idealized two-level atom the detailed balance for the emission and absorption which preserves the Planck formula for the black-body radiation leads to equality of cross-section of absorption and emission.
