In astronomy, axis mundi is the Latin term for the axis of Earth between the celestial poles. In a geocentric coordinate system, this is the axis of rotation of the celestial sphere. Consequently, in ancient Greco-Roman astronomy, the axis mundi [1] is the axis of rotation of the planetary spheres within the classical geocentric model of the ...
The chital or cheetal (Axis axis; / tʃ iː t əl /), also called spotted deer, chital deer and axis deer, is a deer species native to the Indian subcontinent. It was first described by Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach 90 cm (35 in) and females 70 cm (28 in) at the shoulder.
Some directions and planes are defined by symmetry of the crystal system. In monoclinic, trigonal, tetragonal, and hexagonal systems there is one unique axis (sometimes called the principal axis) which has higher rotational symmetry than the other two axes. The basal plane is the plane perpendicular to the principal axis in these crystal ...
The set of words collected together in a lexicon becomes the paradigm from which sentences etc. are formed. Hence, paradigmatic analysis is a method for exploring a syntagm by identifying its constituent paradigm, studying the individual paradigmatic elements, and then reconstructing the process by which the syntagm takes on meaning.
"Syntagmatic" means that one element selects the other element either to precede it or to follow it. For example, the definitive article "the" selects a noun and not a verb. Of particular use in semiotic study, a syntagm is a chain which leads, through syntagmatic analysis, to an understanding of how a sequence of events forms a narrative ...
The Y axis is also in the plane of the equator, passing through extending from 90°W longitude (negative) to 90°E longitude (positive) An example is the NGS data for a brass disk near Donner Summit, in California. Given the dimensions of the ellipsoid, the conversion from lat/lon/height-above-ellipsoid coordinates to X-Y-Z is straightforward ...
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 path. Circumferential (or azimuthal) – following around a curve or circumference of an object.
For positive y- and z-axis, we have to face two different conventions: In case of land vehicles like cars, tanks etc., which use the ENU-system (East-North-Up) as external reference (World frame), the vehicle's (body's) positive y- or pitch axis always points to its left, and the positive z- or yaw axis always points up. World frame's origin is ...
