Frame Of Reference Wikipedia

Frame of reference - Wikipedia.

In physics and astronomy, a frame of reference (or reference frame) is an abstract coordinate system whose origin, orientation, and scale are specified by a set of reference points-geometric points whose position is identified both mathematically (with numerical coordinate values) and physically (signaled by conventional markers).. For n dimensions, n + 1 reference points are ....

Non-inertial reference frame - Wikipedia.

A non-inertial reference frame is a frame of reference that undergoes acceleration with respect to an inertial frame. An accelerometer at rest in a non-inertial frame will, in general, detect a non-zero acceleration. While the laws of motion are the same in all inertial frames, in non-inertial frames, they vary from frame to frame depending on the acceleration..

International Terrestrial Reference System and Frame - Wikipedia.

An International Terrestrial Reference Frame (ITRF) is a realization of the ITRS. Its origin is at the center of mass of the whole earth including the oceans and atmosphere. New ITRF solutions are produced every few years, using the latest mathematical and surveying techniques to attempt to realize the ITRS as precisely as possible. ....

Wire-frame model - Wikipedia.

A wire-frame model, also wireframe model, is a visual representation of a three-dimensional (3D) physical object used in 3D computer graphics.It is created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using (straight) lines or curves.The object is projected into screen ....

Center-of-momentum frame - Wikipedia.

In physics, the center-of-momentum frame (also zero-momentum frame or COM frame) of a system is the unique (up to velocity but not origin) inertial frame in which the total momentum of the system vanishes. The center of momentum of a system is not a location (but a collection of relative momenta/velocities: a reference frame). Thus "center of momentum" means "center ....

Rotating reference frame - Wikipedia.

A rotating frame of reference is a special case of a non-inertial reference frame that is rotating relative to an inertial reference frame.An everyday example of a rotating reference frame is the surface of the Earth. (This article considers only frames rotating about a fixed axis. For more general rotations, see Euler angles.).

Mattress - Wikipedia.

A mattress is a large, usually rectangular pad for supporting a lying person. It is designed to be used as a bed, or on a bed frame as part of a bed. Mattresses may consist of a quilted or similarly fastened case, usually of heavy cloth, containing materials such as hair, straw, cotton, foam rubber, or a framework of metal springs. Mattresses may also be filled with air or water..

IEEE 802.1Q - Wikipedia.

IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames. The standard also contains provisions for a quality-of ....

.NET Framework - Wikipedia.

The .NET Framework (pronounced as "dot net") is a proprietary software framework developed by Microsoft that runs primarily on Microsoft Windows.It was the predominant implementation of the Common Language Infrastructure (CLI) until being superseded by the cross-platform .NET project. It includes a large class library called Framework Class Library (FCL) and provides ....

Simple harmonic motion - Wikipedia.

In mechanics and physics, simple harmonic motion (sometimes abbreviated SHM) is a special type of periodic motion where the restoring force on the moving object is directly proportional to the magnitude of the object's displacement and acts towards the object's equilibrium position. It results in an oscillation which continues indefinitely, if uninhibited by friction or any other ....

Velocity - Wikipedia.

Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.. Velocity is a physical ....

International Earth Rotation and Reference Systems Service.

History. The IERS was established in its present form in 1987 by the International Astronomical Union and the International Union of Geodesy and Geophysics, replacing the earlier International Polar Motion Service (IPMS) and the Earth rotation section of the Bureau International de l'Heure (BIH). The service began operation on January 1, 1988. Since its inception, the IERS has ....

World Geodetic System - Wikipedia.

Definition. The coordinate origin of WGS 84 is meant to be located at the Earth's center of mass; the uncertainty is believed to be less than 2 cm.. The WGS 84 meridian of zero longitude is the IERS Reference Meridian, 5.3 arc seconds or 102 metres (335 ft) east of the Greenwich meridian at the latitude of the Royal Observatory.. The WGS 84 datum surface is an oblate spheroid ....

Group of pictures - Wikipedia.

I picture or I frame (intra coded picture, also called keyframe or i-frame) - a picture that is coded independently of all other pictures. Each GOP begins (in decoding order) with this type of picture. P picture or P frame (predictive coded picture) - contains motion-compensated difference information relative to previously decoded pictures..

Earth-centered, Earth-fixed coordinate system - Wikipedia.

Structure. As with any spatial reference system, ECEF consists of an abstract coordinate system (in this case, a conventional three-dimensional right-handed system), and a geodetic datum that binds the coordinate system to actual locations on the Earth. The ECEF that is used for the Global Positioning System (GPS) is the geocentric WGS 84, which currently includes its own ellipsoid ....

Wayland (display server protocol) - Wikipedia.

The Wayland protocol follows a client-server model in which clients are the graphical applications requesting the display of pixel buffers on the screen, and the server (compositor) is the service provider controlling the display of these buffers.. The Wayland reference implementation has been designed as a two-layer protocol: A low-level layer or wire protocol that handles the inter ....

Dental implant - Wikipedia.

A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor.The basis for modern dental implants is a biologic process called osseointegration, in which materials such as titanium or zirconia form ....
