  2. Formal concept analysis - Wikipedia

    en.wikipedia.org/wiki/Formal_concept_analysis

    The above line diagram consists of circles, connecting line segments, and labels. Circles represent formal concepts. The lines allow to read off the subconcept-superconcept hierarchy. Each object and attribute name is used as a label exactly once in the diagram, with objects below and attributes above concept circles.

  3. Williamson tradeoff model - Wikipedia

    en.wikipedia.org/wiki/Williamson_tradeoff_model

    The Williamson tradeoff model is a theoretical model in the economics of industrial organization which emphasizes the tradeoff associated with horizontal mergers between gains resulting from lower costs of production and the losses associated with higher prices due to greater degree of monopoly power.

  4. Widom line - Wikipedia

    en.wikipedia.org/wiki/Widom_line

    The Widom line has been suggested [3] to separate liquid-like behaviour and gas-like behaviour in supercritical fluids, where the traditional distinction between liquid and gas no longer exists. Specifically, on the low-pressure side of the line, the fluid exhibits a gas-like behavior, while on the high-pressure side, it behaves more like a liquid.

  5. Control chart - Wikipedia

    en.wikipedia.org/wiki/Control_chart

    Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.

  6. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    The behavior of the logistic map is shown in Cobweb plot form. The animation shows the change in behavior as the parameter (r in the figure) is increased from 1 to 4, starting from an initial value of 0.2.) The logistic map is a discrete dynamical system defined by the quadratic difference equation:

  7. Cobweb plot - Wikipedia

    en.wikipedia.org/wiki/Cobweb_plot

    An animated cobweb diagram of the logistic map = (), showing chaotic behaviour for most values of >. A cobweb plot , known also as Lémeray Diagram or Verhulst diagram is a visual tool used in the dynamical systems field of mathematics to investigate the qualitative behaviour of one-dimensional iterated functions , such as the logistic map .

  8. State diagram - Wikipedia

    en.wikipedia.org/wiki/State_diagram

    A state diagram for a door that can only be opened and closed. A state diagram is used in computer science and related fields to describe the behavior of systems. State diagrams require that the system is composed of a finite number of states. Sometimes, this is indeed the case, while at other times this is a reasonable abstraction.

  9. Burndown chart - Wikipedia

    en.wikipedia.org/wiki/Burndown_chart

    Actual work remaining line This shows the actual work remaining. At the start point, the actual work remaining is the same as the ideal work remaining but as time progresses, the actual work line fluctuates above and below the ideal line depending on this disparity between estimates and how effective the team is.
