2. Homogeneous function - Wikipedia

   en.wikipedia.org/wiki/Homogeneous_function

   In mathematics, a homogeneous function is a function of several variables such that the following holds: If each of the function's arguments is multiplied by the same scalar, then the function's value is multiplied by some power of this scalar; the power is called the degree of homogeneity, or simply the degree.

3. Rankine scale - Wikipedia

   en.wikipedia.org/wiki/Rankine_scale

   The Rankine scale is used in engineering systems where heat computations are done using degrees Fahrenheit. [3] The symbol for degrees Rankine is °R [2] (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). By analogy with the SI unit kelvin, some authors term the unit Rankine, omitting the degree symbol. [4] [5]

4. Temperature coefficient - Wikipedia

   en.wikipedia.org/wiki/Temperature_coefficient

   Here α has the dimension of an inverse temperature and can be expressed e.g. in 1/K or K −1. If the temperature coefficient itself does not vary too much with temperature and α Δ T ≪ 1 {\displaystyle \alpha \Delta T\ll 1} , a linear approximation will be useful in estimating the value R of a property at a temperature T , given its value ...

5. Kelvin - Wikipedia

   en.wikipedia.org/wiki/Kelvin

   In particular, the committee proposed redefining the kelvin such that the Boltzmann constant (k B) would take the exact value 1.380 6505 × 10 −23 J/K. [46] The committee hoped the program would be completed in time for its adoption by the CGPM at its 2011 meeting, but at the 2011 meeting the decision was postponed to the 2014 meeting when it ...

6. R-value (insulation) - Wikipedia

   en.wikipedia.org/wiki/R-value_(insulation)

   The R-value is the building industry term [3] for thermal resistance "per unit area." [4] It is sometimes denoted RSI-value if the SI units are used. [5] An R-value can be given for a material (e.g., for polyethylene foam), or for an assembly of materials (e.g., a wall or a window). In the case of materials, it is often expressed in terms of R ...

7. Degree (temperature) - Wikipedia

   en.wikipedia.org/wiki/Degree_(temperature)

   Common scales of temperature measured in degrees: Celsius (°C) Fahrenheit (°F) Rankine (°R or °Ra), which uses the Fahrenheit scale, adjusted so that 0 degrees Rankine is equal to absolute zero. Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The ...

9. Coefficient of determination - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_determination

   Ordinary least squares regression of Okun's law.Since the regression line does not miss any of the points by very much, the R 2 of the regression is relatively high.. In statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).
