2. Nondimensionalization - Wikipedia

   en.wikipedia.org/wiki/Nondimensionalization

   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 ...

3. Scale analysis (statistics) - Wikipedia

   en.wikipedia.org/wiki/Scale_analysis_(statistics)

   The item-total correlation approach is a way of identifying a group of questions whose responses can be combined into a single measure or scale. This is a simple approach that works by ensuring that, when considered across a whole population, responses to the questions in the group tend to vary together and, in particular, that responses to no individual question are poorly related to an ...

4. Dimensionless quantity - Wikipedia

   en.wikipedia.org/wiki/Dimensionless_quantity

   Quantities having dimension one, dimensionless quantities, regularly occur in sciences, and are formally treated within the field of dimensional analysis.In the 19th century, French mathematician Joseph Fourier and Scottish physicist James Clerk Maxwell led significant developments in the modern concepts of dimension and unit.

   This technique can ease the analysis of the problem at hand, and reduce the number of free parameters. Small or large sizes of certain dimensionless parameters indicate the importance of certain terms in the equations for the studied flow. This may provide possibilities to neglect terms in (certain areas of) the considered flow.

7. Scale (analytical tool) - Wikipedia

   en.wikipedia.org/wiki/Scale_(analytical_tool)

   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).

8. Multiple-scale analysis - Wikipedia

   en.wikipedia.org/wiki/Multiple-scale_analysis

   In mathematics and physics, multiple-scale analysis (also called the method of multiple scales) comprises techniques used to construct uniformly valid approximations to the solutions of perturbation problems, both for small as well as large values of the independent variables. This is done by introducing fast-scale and slow-scale variables for ...
