61Total fertility rate — Not to be confused with birth rate. A world map showing countries by fertility rate, 2005 2010 …
62Illusory motion — The term illusory motion, also known as motion illusion, is used to define the appearance of movement in a static image. This is an optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color… …
63perpetual motion — Mech. the motion of a theoretical mechanism that, without any losses due to friction or other forms of dissipation of energy, would continue to operate indefinitely at the same rate without any external energy being applied to it. [1585 95] * * * …
64Short rate model — In the context of interest rate derivatives, a short rate model is a mathematical model that describes the future evolution of interest rates by describing the future evolution of the short rate.The short rateThe short rate, usually written r t… …
65Air Motion Transformer — The Air Motion Transformer (AMT) is a loudspeaker mechanism, or audio transducer, invented by Dr. Oskar Heil. It operates on a different principle than both electrodynamic and electrostatic speaker drivers. The AMT moves air in an augmented, semi …
66Churn rate — (sometimes called attrition rate), in its broadest sense, is a measure of the number of individuals or items moving into or out of a collective over a specific period of time. It is one of two primary factors that determine the steady state level …
67Newton's laws of motion — Relations between the forces acting on a body and the motion of the body, formulated by Isaac Newton. The laws describe only the motion of a body as a whole and are valid only for motions relative to a reference frame. Usually, the reference… …
68Differential motion — differential dif fer*en tial, a. [Cf. F. diff[ e]rentiel.] 1. Relating to or indicating a difference; creating a difference; discriminating; special; as, differential characteristics; differential duties; a differential rate. [1913 Webster] For… …
69image motion compensation — A movement intentionally imparted to film at such a rate as to compensate for the forward motion of an air or space vehicle when photographing ground objects. It is an act of synchronizing the target image with the recorder. Image motion… …
70Facial motion capture — is the process of electronically converting the movements of a person s face into a digital database using cameras or laser scanners. This database may then be used to produce CG (computer graphics) computer animation for movies, games, or real… …
