One important use is in the analysis of control systems. One of the simplest characteristic units is the doubling time of a system experiencing exponential growth , or conversely the half-life of a system experiencing exponential decay ; a more natural pair of characteristic units is mean age/ mean lifetime , which correspond to base e rather ...

Dimensionless quantities, or quantities of dimension one, [1] are quantities implicitly defined in a manner that prevents their aggregation into units of measurement. [2] [3] Typically expressed as ratios that align with another system, these quantities do not necessitate explicitly defined units.
Precision teaching is a precise and systematic method of evaluating instructional tactics and curricula. It is one of the few quantitative analyses of behavior forms of applied behavior analysis. It comes from a very strong quantitative scientific basis and was pioneered by Ogden Lindsley in the 1960s based largely on Skinner's operant ...
However, method is an ambiguous concept in language teaching and has been used in many different ways. According to Bell, this variety in use "offers a challenge for anyone wishing to enter into the analysis or deconstruction of methods". [5] The methods of teaching language may be characterized into three principal views:
A Mokken scale is a unidimensional scale that consists of hierarchically-ordered items that measure the same underlying, latent concept. This method is named after the political scientist Rob Mokken who suggested it in 1971. [1] Mokken Scales have been used in psychology, [2] education, [3] [4] political science, [1] [5] public opinion, [6 ...
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
The scale of analysis encompasses both the analytical choice of how to observe a given system or object of study, and the role of the observer in determining the identity of the system. [ 2 ] [ 3 ] This analytical tool is central to multi-scale analysis (see for example, MuSIASEM , land-use analysis).
