Mccumber relation
WebThe McCumber relation is usually used to relate the absorption and emission cross-sections due to its great validity and simplicity [2,28]. The McCumber relation takes the form [27]: P c :I ; LP _ :I ; t ? f ¥ i > X(1) where P c :I ; is the emission cross-section, P WebIn this paper, I argue against Terry Pinkard's account of the relation between Deweyian pragmatism and Hegelian idealism. Instead of thinking that their affinity concerns the issue of normative authority, as Pinkard does, I argue that we should trace their affinity to Dewey's appropriation of Hegel's naturalism, especially his theory of habits.

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… Web14 aug. 2024 · 1、McCumber 理论The McCumber relation (or McCumber theory) refers to the effective cross-sections of absorption and emission of light in the physics of solid-state lasers 12.DefinitionLet a() be the effective absorption cross-section e() be effective emission cross-sections at frequency , and let be the . 2、effective temperature of the medium.
Web5 mei 2011 · All spectral measurements were performed with a scanning spectrum analyzer, providing a spectral resolution down to 0.05 nm. By applying the McCumber relation in combination with the Fuchtbauer-Ladenburg method, we were able to obtain a valid emission cross section over the whole range of interest from the measured data. Web17 mei 2024 · Then, the absorption cross-section spectra were calculated using McCumber relation. In parallel, the absorption cross-section spectra were also obtained from the measured absorption spectrum, and compared with those obtained from the McCumber relation. The comparison shows that both methods give consistent result of absorption …
