  2. Neal McDonough - Wikipedia

    en.wikipedia.org/wiki/Neal_McDonough

    His childhood nickname was "Headster", which McDonough says originated in his brothers' teasing him about the size of his head. [4] He graduated from Barnstable High School , and attended Syracuse University , where he was initiated and became a member of the Sigma Chi Fraternity and graduated with a Bachelor of Fine Arts degree in 1988.

  3. Hudson's equation - Wikipedia

    en.wikipedia.org/wiki/Hudson's_equation

    Hudson's equation, also known as Hudson formula, is an equation used by coastal engineers to calculate the minimum size of riprap (armourstone) required to provide satisfactory stability characteristics for rubble structures such as breakwaters under attack from storm wave conditions.

  4. Gaussian function - Wikipedia

    en.wikipedia.org/wiki/Gaussian_function

    Any least squares estimation algorithm can provide numerical estimates for the variance of each parameter (i.e., the variance of the estimated height, position, and width of the function). One can also use Cramér–Rao bound theory to obtain an analytical expression for the lower bound on the parameter variances, given certain assumptions ...

  5. Height function - Wikipedia

    en.wikipedia.org/wiki/Height_function

    A height function is a function that quantifies the complexity of mathematical objects. In Diophantine geometry , height functions quantify the size of solutions to Diophantine equations and are typically functions from a set of points on algebraic varieties (or a set of algebraic varieties) to the real numbers .

  6. Perry–Robertson formula - Wikipedia

    en.wikipedia.org/wiki/Perry–Robertson_formula

    The Perry–Robertson formula is a mathematical formula which is able to produce a good approximation of buckling loads in long slender columns or struts, and is the basis for the buckling formulation adopted in EN 1993. The formula in question can be expressed in the following form:

  7. Organ flue pipe scaling - Wikipedia

    en.wikipedia.org/wiki/Organ_flue_pipe_scaling

    Relationship between number of feet, octave and size of an open flue pipe (1′ = 1 foot = about 32 cm) Play ⓘ Scaling is the ratio of an organ pipe's diameter to its length. The scaling of a pipe is a major influence on its timbre. Reed pipes are scaled according to different formulas than for flue pipes.

  8. Curve of constant width - Wikipedia

    en.wikipedia.org/wiki/Curve_of_constant_width

    In geometry, a curve of constant width is a simple closed curve in the plane whose width (the distance between parallel supporting lines) is the same in all directions. The shape bounded by a curve of constant width is a body of constant width or an orbiform , the name given to these shapes by Leonhard Euler . [ 1 ]

  9. Area - Wikipedia

    en.wikipedia.org/wiki/Area

    Although there are 10 mm in 1 cm, there are 100 mm 2 in 1 cm 2. Calculation of the area of a square whose length and width are 1 metre would be: 1 metre × 1 metre = 1 m 2. and so, a rectangle with different sides (say length of 3 metres and width of 2 metres) would have an area in square units that can be calculated as: 3 metres × 2 metres ...
