  2. Bennett acceptance ratio - Wikipedia

    en.wikipedia.org/wiki/Bennett_acceptance_ratio

    The Bennett acceptance ratio method (BAR) is an algorithm for estimating the difference in free energy between two systems (usually the systems will be simulated on the computer). It was suggested by Charles H. Bennett in 1976.

  3. Barre (exercise) - Wikipedia

    en.wikipedia.org/wiki/Barre_(exercise)

    Barre (UK: / b ɑː /, US: / b ɑːr / bar) is a form of physical exercise, usually conducted in group classes in gyms or specialty studios. [1] It is distinguished from other group fitness activities by its use of the ballet barre and its incorporation of movements derived from ballet . [ 2 ]

  4. Charpy impact test - Wikipedia

    en.wikipedia.org/wiki/Charpy_impact_test

    The notch in the sample affects the results of the impact test, [6] thus it is necessary for the notch to be of regular dimensions and geometry. The size of the sample can also affect results, since the dimensions determine whether or not the material is in plane strain. This difference can greatly affect the conclusions made. [7]

  5. Searle's bar method - Wikipedia

    en.wikipedia.org/wiki/Searle's_bar_method

    ΔQ is the heat supplied to the bar in time Δt; k is the coefficient of thermal conductivity of the bar. A is the cross-sectional area of the bar, ΔT bar is the temperature difference between each end of the bar; L is the length of the bar; and the heat ΔQ absorbed by water in a time interval of Δt is:

  6. Absorption (electromagnetic radiation) - Wikipedia

    en.wikipedia.org/wiki/Absorption_(electromagnetic...

    An overview of absorption of electromagnetic radiation.This example shows the general principle using visible light as a specific example. A white light source—emitting light of multiple wavelengths—is focused on a sample (the pairs of complementary colors are indicated by the yellow dotted lines).

  7. Desorption - Wikipedia

    en.wikipedia.org/wiki/Desorption

    Desorption is the physical process where adsorbed atoms or molecules are released from a surface into the surrounding vacuum or fluid. This occurs when a molecule gains enough energy to overcome the activation barrier and the binding energy that keep it attached to the surface.

  8. Fixed effects model - Wikipedia

    en.wikipedia.org/wiki/Fixed_effects_model

    In statistics, a fixed effects model is a statistical model in which the model parameters are fixed or non-random quantities. This is in contrast to random effects models and mixed models in which all or some of the model parameters are random variables.

  9. Absorbing set - Wikipedia

    en.wikipedia.org/wiki/Absorbing_set

    A set is said to absorb a point if it absorbs the singleton set {}. A set A {\displaystyle A} absorbs the origin if and only if it contains the origin; that is, if and only if 0 ∈ A . {\displaystyle 0\in A.}
