2. Nondimensionalization - Wikipedia

   en.wikipedia.org/wiki/Nondimensionalization

   Nondimensionalization is the partial or full removal of physical dimensions from an equation involving physical quantities by a suitable substitution of variables. This technique can simplify and parameterize problems where measured units are involved. It is closely related to dimensional analysis.

3. Scale analysis (statistics) - Wikipedia

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

   In statistics, scale analysis is a set of methods to analyze survey data, in which responses to questions are combined to measure a latent variable. These items can ...

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.

5. Non-dimensionalization and scaling of the Navier–Stokes ...

   en.wikipedia.org/wiki/Non-dimensionalization_and...

   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.

   Chemical engineering, material science, mechanics (A scale to show the energy needed for detaching two solid particles) [13] [14] Cost of transport: COT = energy efficiency, economics (ratio of energy input to kinetic motion) Damping ratio

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. Scale (ratio) - Wikipedia

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

   Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. [1] In such cases the scale is dimensionless and exact throughout the model or drawing. The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale.

9. Dimensional analysis - Wikipedia

   en.wikipedia.org/wiki/Dimensional_analysis

   In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric current) and units of measurement (such as metres and grams) and tracking these dimensions as calculations or comparisons are performed.
