    en.wikipedia.org/wiki/N2_Chart

    The N 2 chart or N 2 diagram (pronounced "en-two" or "en-squared") is a chart or diagram in the shape of a matrix, representing functional or physical interfaces between system elements. It is used to systematically identify, define, tabulate, design, and analyze functional and physical interfaces.

  3. Relocation (computing) - Wikipedia

    en.wikipedia.org/wiki/Relocation_(computing)

    Relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. [1] [2] Prior to the advent of multiprocess systems, and still in many embedded systems, the addresses for objects are absolute starting at a known location, often zero.

  4. Help:Table/Advanced - Wikipedia

    en.wikipedia.org/wiki/Help:Table/Advanced

    Using two columns like this does have the disadvantage that searching the web page (either with a browser or a search engine) will usually not be able to find text that straddles the column boundary. Also, if the table has cell spacing (and thus border-collapse=separate ), meaning that cells have separate borders with a gap in between, that gap ...

    When the letter X is preceded by a space, this means "by". For example, a chamfer may be called out as X [2] or ( ) number of places—for example, 8X or (8) When a dimension is used in multiple places either of these prefixes can be added to the dimension to define how many times this dimension is used. This example signifies eight places.

  6. Nine lemma - Wikipedia

    en.wikipedia.org/wiki/Nine_lemma

    In mathematics, the nine lemma (or 3×3 lemma) is a statement about commutative diagrams and exact sequences valid in the category of groups and any abelian category.It states: if the diagram to the right is a commutative diagram and all columns as well as the two bottom rows are exact, then the top row is exact as well.

  7. Help:Advanced table formatting - Wikipedia

    en.wikipedia.org/wiki/Help:Advanced_table_formatting

    If just 2 columns are being swapped within 1 table, then cut/paste editing (of those column entries) is typically faster than column-prefixing, sorting and de-prefixing. Another alternative is to copy the entire table from the displayed page, paste the text into a spreadsheet, move the columns as you will.

    The left hand is held with the thumb, first finger and second finger mutually at right angles. The Thumb represents F - Thrust (or resulting Motion). The First finger represents B - Field. The Second finger represents I or V - Current (in the classical direction, from positive to negative).

  9. Swimlane - Wikipedia

    en.wikipedia.org/wiki/Swimlane

    Swimlane diagrams first appeared in the 1940s as a variation of the flow process chart called multi-column charts. [1] They were called Swim Lane diagrams by Geary Rummler and Alan Brache in their book Improving Performance (1990). They were first introduced to computer-based diagramming by iGrafx. Swimlanes are also known as "Rummler-Brache ...
