  2. Aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio

    For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [1] [2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction. The values x and y do ...

  3. Full width at half maximum - Wikipedia

    en.wikipedia.org/wiki/Full_width_at_half_maximum

    In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y -axis which are half the maximum amplitude.

  4. Ship measurements - Wikipedia

    en.wikipedia.org/wiki/Ship_measurements

    Used mainly to determine the minimum water depth for safe passage of a vessel and to calculate the vessel's displacement (obtained from ship's stability tables) so as to determine the mass of cargo on board. Draft, Air – Air Draft/Draught is the distance from the water line to the highest point on a ship (including antennas) while it is ...

  5. Tree crown measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_crown_measurement

    American Forests, for example, uses a formula to calculate Big Tree Points as part of their Big Tree Program [3] that awards a tree 1 point for each foot of height, 1 point for each inch of girth, and ⁠ 1 / 4 ⁠ point for each foot of crown spread. The tree whose point total is the highest for that species is crowned as the champion in their ...

  6. Image resolution - Wikipedia

    en.wikipedia.org/wiki/Image_resolution

    An image of N pixels height by M pixels wide can have any resolution less than N lines per picture height, or N TV lines. But when the pixel counts are referred to as "resolution", the convention is to describe the pixel resolution with the set of two positive integer numbers, where the first number is the number of pixel columns (width) and ...

  7. Display aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Display_aspect_ratio

    It is expressed as two numbers separated by a colon (x:y), where x corresponds to the width and y to the height. Common aspect ratios for displays, past and present, include 5:4, 4:3, 16:10, and 16:9. To distinguish: The display aspect ratio (DAR) is calculated from the physical width and height of a display, measured each in inch or cm ...

    Could you guess someone’s height just from a photo of them drinking Starbucks?. As ridiculous as all that might sound, it’s exactly how TikTok user @kentai.haven has amassed more than 1.2 ...

  9. Slenderness ratio - Wikipedia

    en.wikipedia.org/wiki/Slenderness_ratio

    Structural engineers generally consider a skyscraper as slender if the height:width ratio exceeds 10:1 or 12:1. Slim towers require the adoption of specific measures to counter the high strengths of wind in the vertical cantilever , like including additional structures to endow greater rigidity to the building or diverse types of tuned mass ...
