  2. Plotting algorithms for the Mandelbrot set - Wikipedia

    The values are checked during each iteration to see whether they have reached a critical "escape" condition, or "bailout". If that condition is reached, the calculation is stopped, the pixel is drawn, and the next x, y point is examined. For some starting values, escape occurs quickly, after only a small number of iterations.

  3. Approximate string matching - Wikipedia

    en.wikipedia.org/wiki/Approximate_string_matching

    The closeness of a match is measured in terms of the number of primitive operations necessary to convert the string into an exact match. This number is called the edit distance between the string and the pattern. The usual primitive operations are: [1] insertion: cot → coat; deletion: coat → cot; substitution: coat → cost

    DBEdit – a free front end for MySQL and other databases; HeidiSQL – a full featured free front end that runs on Windows, and can connect to local or remote MySQL servers to manage databases, tables, column structure, and individual data records. Also supports specialised GUI features for date/time fields and enumerated multiple-value fields [6]

  5. Weighted least squares - Wikipedia

    en.wikipedia.org/wiki/Weighted_least_squares

    Weighted least squares (WLS), also known as weighted linear regression, [1] [2] is a generalization of ordinary least squares and linear regression in which knowledge of the unequal variance of observations (heteroscedasticity) is incorporated into the regression.

  6. Matched filter - Wikipedia

    en.wikipedia.org/wiki/Matched_filter

    where [] is the input as a function of the independent variable , and [] is the filtered output. Though we most often express filters as the impulse response of convolution systems, as above (see LTI system theory ), it is easiest to think of the matched filter in the context of the inner product , which we will see shortly.

  7. Frame check sequence - Wikipedia

    en.wikipedia.org/wiki/Frame_check_sequence

    By far the most popular FCS algorithm is a cyclic redundancy check (CRC), used in Ethernet and other IEEE 802 protocols with 32 bits, in X.25 with 16 or 32 bits, in HDLC with 16 or 32 bits, in Frame Relay with 16 bits, [3] in Point-to-Point Protocol (PPP) with 16 or 32 bits, and in other data link layer protocols.

  8. Matched Z-transform method - Wikipedia

    The gain must be adjusted to normalize the desired gain, typically set to match the analog filter's gain at DC by setting = and = and solving for . [ 3 ] [ 6 ] Since the mapping wraps the s -plane's j ω {\displaystyle j\omega } axis around the z -plane's unit circle repeatedly, any zeros (or poles) greater than the Nyquist frequency will be ...
