  2. Machine taper - Wikipedia

    en.wikipedia.org/wiki/Machine_taper

    The taper angle of the Morse taper varies somewhat with size but is typically 1.49 degrees (around 3 degrees included). Some modular orthopedic total hip implants use a Morse taper to mate components together. [2] Similarly, some dental implants use a Morse taper to connect components. [3]

  3. Degrees of freedom (statistics) - Wikipedia

    en.wikipedia.org/.../Degrees_of_freedom_(statistics)

    In equations, the typical symbol for degrees of freedom is ν (lowercase Greek letter nu).In text and tables, the abbreviation "d.f." is commonly used. R. A. Fisher used n to symbolize degrees of freedom but modern usage typically reserves n for sample size.

  4. Degrees of freedom - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom

    In many scientific fields, the degrees of freedom of a system is the number of parameters of the system that may vary independently. For example, a point in the plane has two degrees of freedom for translation : its two coordinates ; a non-infinitesimal object on the plane might have additional degrees of freedoms related to its orientation .

  5. Degrees of freedom (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom_(mechanics)

    A mechanism or linkage containing a number of connected rigid bodies may have more than the degrees of freedom for a single rigid body. Here the term degrees of freedom is used to describe the number of parameters needed to specify the spatial pose of a linkage. It is also defined in context of the configuration space, task space and workspace ...

  6. Degrees of freedom (physics and chemistry) - Wikipedia

    By the equipartition theorem, internal energy per mole of gas equals c v T, where T is absolute temperature and the specific heat at constant volume is c v = (f)(R/2). R = 8.314 J/(K mol) is the universal gas constant, and "f" is the number of thermodynamic (quadratic) degrees of freedom, counting the number of ways in which energy can occur.

  7. Potential energy surface - Wikipedia

    en.wikipedia.org/wiki/Potential_energy_surface

    An example is the Morse/Long-range potential. It is helpful to use the analogy of a landscape: for a system with two degrees of freedom (e.g. two bond lengths), the value of the energy (analogy: the height of the land) is a function of two bond lengths (analogy: the coordinates of the position on the ground). [1]

  8. Discrete Morse theory - Wikipedia

    en.wikipedia.org/wiki/Discrete_Morse_theory

    Discrete Morse theory is a combinatorial adaptation of Morse theory developed by Robin Forman. The theory has various practical applications in diverse fields of applied mathematics and computer science , such as configuration spaces , [ 1 ] homology computation, [ 2 ] [ 3 ] denoising , [ 4 ] mesh compression , [ 5 ] and topological data analysis .

  9. Cochran's theorem - Wikipedia

    en.wikipedia.org/wiki/Cochran's_theorem

    where F 1,n − 1 is the F-distribution with 1 and n − 1 degrees of freedom (see also Student's t-distribution). The final step here is effectively the definition of a random variable having the F-distribution.
