Motion compensationMotion compensation in computing, is an algorithmic technique used to predict a frame in a video, given the previous and/or future frames by accounting for motion of the camera and/or objects in the video. It is employed in the encoding of video data for video compression, for example in the generation of MPEG-2 files. Motion compensation describes a picture in terms of the transformation of a reference picture to the current picture. The reference picture may be previous in time or even from the future.
Full motion racing simulatorA full motion racing simulator, sometimes called a full motion sim rig, is a motion simulator that is purposed for racing, and must provide motion simulation in all six degrees of freedom, as defined by the aviation simulator industry many decades ago. The six degrees of freedom coincide with Earth physics, and are commonly referred to (in both aircraft, watercraft and other vehicles) as: The three translational movements: Surge, sway and heave (front/back motion, side-to-side motion and up/down motion, respectively) The three rotational movements: Roll, pitch, and yaw (rotation around the normal, transverse and longitudinal axes, respectively) Simulations of these six degrees of freedom are achieved by 2 fundamentally different approaches.
Bending momentIn solid mechanics, a bending moment is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend. The most common or simplest structural element subjected to bending moments is the beam. The diagram shows a beam which is simply supported (free to rotate and therefore lacking bending moments) at both ends; the ends can only react to the shear loads. Other beams can have both ends fixed (known as encastre beam); therefore each end support has both bending moments and shear reaction loads.
