~2.8: Cauliflower: San-Hoon Kim used a direct scanning method and a mathematical analysis of the cross section of a cauliflower to conclude that the fractal dimension of it is ~2.8. [49] 2.97: Lung surface: The alveoli of a lung form a fractal surface close to 3. [43] Calculated (,) Multiplicative cascade
The difference between this calculation and that for the Mandelbrot set is that the real and imaginary components are set to their respective absolute values before squaring at each iteration. [1] The mapping is non-analytic because its real and imaginary parts do not obey the Cauchy–Riemann equations. [2]
Successive parabolic interpolation is a technique for finding the extremum (minimum or maximum) of a continuous unimodal function by successively fitting parabolas (polynomials of degree two) to a function of one variable at three unique points or, in general, a function of n variables at 1+n(n+3)/2 points, and at each iteration replacing the "oldest" point with the extremum of the fitted ...

[8] anamorphic format 1. The technique of shooting a widescreen picture on visual recording media with a non-widescreen native aspect ratio. 2. A projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen. anamorphic widescreen angle of light angle of view
One feature of most escape time fractal programs or algebraic-based fractals is a maximum iteration setting. Increasing the iteration count is required if the image is magnified so that fine detail is not lost. Limiting the maximum iterations is important when a device's processing power is low. Coloring options often allow colors to be randomised.
Muller's method fits a parabola, i.e. a second-order polynomial, to the last three obtained points f(x k-1), f(x k-2) and f(x k-3) in each iteration. One can generalize this and fit a polynomial p k,m (x) of degree m to the last m+1 points in the k th iteration. Our parabola y k is written as p k,2 in this notation. The degree m must be 1 or
Revised countable support iterations of semi-proper forcings are semi-proper and thus preserve . Some non-semi-proper forcings, such as Namba forcing , can be iterated with appropriate cardinal collapses while preserving ω 1 {\displaystyle \omega _{1}} using methods developed by Saharon Shelah .
