2. ### Chip log - Wikipedia

en.wikipedia.org/wiki/Chip_log

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. ### Log bridge - Wikipedia

en.wikipedia.org/wiki/Log_bridge

A log bridge is a timber bridge that uses logs that fall naturally or are intentionally felled or placed across streams. The first man-made bridges with significant span were probably intentionally felled trees .

4. ### Log–log plot - Wikipedia

en.wikipedia.org/wiki/Loglog_plot

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

en.wikipedia.org/wiki/Log_reduction

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. ### Trunk (botany) - Wikipedia

en.wikipedia.org/wiki/Trunk_(botany)

The term "log" is informally used in English to describe any felled trunk not rooted in the ground, whose roots are detached. A stump is the part of a trunk remaining in the ground after the tree has been felled, or the earth-end of an uprooted tree which retains its un-earthed roots.

7. ### LogSumExp - Wikipedia

en.wikipedia.org/wiki/LogSumExp

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:

8. ### logparser - Wikipedia

en.wikipedia.org/wiki/Logparser

logparser is a flexible command line utility that was initially written by Gabriele Giuseppini, a Microsoft employee, to automate tests for IIS logging.It was intended for use with the Windows operating system, and was included with the IIS 6.0 Resource Kit Tools.

9. ### Logarithm of a matrix - Wikipedia

en.wikipedia.org/wiki/Logarithm_of_a_matrix

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.
