    A USAF 1951 resolution chart in PDF format is provided by Yoshihiko Takinami. This chart should be printed such that the side of the square of the 1st element of the group -2 should be 10 mm long. USAF 1951 Resolution Target Further explanations and examples; Koren 2003: Norman Koren's updated resolution chart better suited for computer analysis

  3. Geologic time scale - Wikipedia

    en.wikipedia.org/wiki/Geologic_time_scale

    As such, this table is not to scale and does not accurately represent the relative time-spans of each geochronologic unit. While the Phanerozoic Eon looks longer than the rest, it merely spans ~539 million years (~12% of Earth's history), whilst the previous three eons [note 2] collectively span ~3,461 million years (~76% of Earth's history ...

    Chikou span calculation: today's closing price projected back 26 days on the chart. Also called the lagging span it is used as a support/resistance aid. If the Chikou Span or the green line crosses the price in the bottom-up direction, that is a buy signal. If the green line crosses the price from the top-down, that is a sell signal.

  5. Radar chart - Wikipedia

    en.wikipedia.org/wiki/Radar_chart

    (Radar charts are used to examine the relative values for a single data point (e.g., point 3 is large for variables 2 and 4, small for variables 1, 3, 5, and 6) and to locate similar points or dissimilar points.) [5] Are there outliers? Radar charts are a useful way to display multivariate observations with an arbitrary number of variables. [6]

  6. Chesapeake Bay Bridge - Wikipedia

    en.wikipedia.org/wiki/Chesapeake_Bay_Bridge

    The original span, opened in 1952 and with a length of 4 miles (6.4 km), was the world's longest continuous over-water steel structure. The parallel span was added in 1973. The bridge is named for William Preston Lane Jr. , who as the 52nd Governor of Maryland launched its construction in the late 1940s after decades of political indecision and ...

  7. Makespan - Wikipedia

    en.wikipedia.org/wiki/Makespan

    In operations research, the makespan of a project is the length of time that elapses from the start of work to the end. This type of multi-mode resource constrained project scheduling problem (MRCPSP) seeks to create the shortest logical project schedule, by efficiently using project resources, adding the lowest number of additional resources as possible to achieve the minimum makespan.

  8. Ape index - Wikipedia

    en.wikipedia.org/wiki/Ape_index

    The ape index is usually defined as the ratio of arm span to height. However, an alternative approach is arm span minus height with the result being positive, 0 or negative. Unlike the dimensionless ratio, this calculation produces a numeric value in the units of measurement used to represent the height and arm span.

  9. Program evaluation and review technique - Wikipedia

    PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F).. The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project.
