  3. Geometric terms of location - Wikipedia

    en.wikipedia.org/wiki/Geometric_terms_of_location

    Common geometric terms of location are: Radial (solid and colored lines) and circumferential roads (dashed and gray lines) in Metro Manila's road network. Axial – along the center of a round body, or the axis of rotation of a body; Radial – along a direction pointing along a radius from the center of an object, or perpendicular to a curved ...

  4. Limits of stability - Wikipedia

    en.wikipedia.org/wiki/Limits_of_stability

    In simpler terms, LoS represents the maximum distance an individual can intentionally sway in any direction without losing balance or needing to take a step. [2] The typical range of stable swaying is approximately 12.5° in the front-back (antero-posterior) direction and 16° in the side-to-side (medio-lateral) direction. [ 3 ]

  5. Sidelobes - Wikipedia

    en.wikipedia.org/wiki/Sidelobes

    In antenna engineering, sidelobes are the lobes (local maxima) of the far field radiation pattern of an antenna or other radiation source, that are not the main lobe.. The radiation pattern of most antennas shows a pattern of "lobes" at various angles, directions where the radiated signal strength reaches a maximum, separated by "nulls", angles at which the radiated signal strength falls to zero.

    en.wikipedia.org/wiki/Spatial_relation

    An internal directional relation specifies where an object is located inside the reference object while an external relations specifies where the object is located outside of the reference objects. Examples for internal directional relations: left; on the back; athwart, abaft

    A-type star In the Harvard spectral classification system, a class of main-sequence star having spectra dominated by Balmer absorption lines of hydrogen. Stars of spectral class A are typically blue-white or white in color, measure between 1.4 and 2.1 times the mass of the Sun, and have surface temperatures of 7,600–10,000 kelvin.

  8. Directional selection - Wikipedia

    en.wikipedia.org/wiki/Directional_selection

    A highly indicative test of changes in allele frequencies is the QTL sign test, and other tests include the Ka/Ks ratio test and the relative rate test. The QTL sign test compares the number of antagonistic QTL to a neutral model, and allows for testing of directional selection against genetic drift . [ 11 ]

  9. Anatomy - Wikipedia

    en.wikipedia.org/wiki/Anatomy

    Anatomy (from Ancient Greek ἀνατομή (anatomḗ) 'dissection') is the branch of morphology concerned with the study of the internal structure of organisms and their parts. [2] Anatomy is a branch of natural science that deals with the structural organization of living things.
