  2. Chip log - Wikipedia

    A chip log, also called common log, ship log, or just log, is a navigation tool mariners use to estimate the speed of a vessel through water. The word knot , to mean nautical mile per hour , derives from this measurement method.

  3. Semi-log plot - Wikipedia

    In science and engineering, a semi-log plot/graph or semi-logarithmic plot/graph has one axis on a logarithmic scale, the other on a linear scale.It is useful for data with exponential relationships, where one variable covers a large range of values, or to zoom in and visualize that - what seems to be a straight line in the beginning - is in fact the slow start of a logarithmic curve that is ...

  4. Loglog plot - Wikipedia

    In science and engineering, a loglog graph or loglog plot is a two-dimensional graph of numerical data that uses logarithmic scales on both the horizontal and vertical axes. Power functions – relationships of the form y = a x k {\displaystyle y=ax^{k}} – appear as straight lines in a loglog graph, with the exponent corresponding to ...

  5. Log reduction - Wikipedia

    Log reduction is a measure of how thoroughly a decontamination process reduces the concentration of a contaminant.It is defined as the common logarithm of the ratio of the levels of contamination before and after the process, so an increment of 1 corresponds to a reduction in concentration by a factor of 10.

  6. Bandar-log - Wikipedia

    Bandar-log communicate almost entirely through the repetition of other animals' speech. The Road-Song of the Bandar-log is a companion poem to 'Kaa's Hunting', and demonstrates Kipling's strong adherence to poetic form. In other media. The Bandar-log appear in Disney's The Jungle Book.

  7. Web log analysis software - Wikipedia

    Web log analysis software (also called a web log analyzer) is a kind of web analytics software that parses a server log file from a web server, and based on the values contained in the log file, derives indicators about when, how, and by whom a web server is visited. Reports are usually generated immediately, but data extracted from the log ...

  8. LogSumExp - Wikipedia

    The LSE function is often encountered when the usual arithmetic computations are performed on a logarithmic scale, as in log probability. Similar to multiplication operations in linear-scale becoming simple additions in log-scale, an addition operation in linear-scale becomes the LSE in log-scale:

  9. Logarithm of a matrix - Wikipedia

    Definition. The exponential of a matrix A is defined by =!. Given a matrix B, another matrix A is said to be a matrix logarithm of B if e A = B.Because the exponential function is not bijective for complex numbers (e.g. = =), numbers can have multiple complex logarithms, and as a consequence of this, some matrices may have more than one logarithm, as explained below.
