31Equation of time — The equation of time is the difference over the course of a year between time as read from a sundial and time as read from a clock, measured in an ideal situation (ie. in a location at the centre of a time zone, and which does not use daylight… …
32The Time Traveller (character) — The Time Traveller is the fictional protagonist in H. G. Wells s The Time Machine , a novel published in 1895. It tells the story of an amateur inventor and scientist known only as The Time Traveller . In The Chronic Argonauts The Chronic… …
33Coordinate time — In the theory of relativity, it is convenient to express results in terms of a spacetime coordinate system relative to an implied observer. In many (but not all) coordinate systems, an event is specified by one time coordinate and three spatial… …
34Arrow of time — This article is an overview of the subject. For a more technical discussion and for information related to current research, see Entropy (arrow of time). In the natural sciences, arrow of time, or time’s arrow, is a term coined in 1927 by British …
35Finite-difference time-domain method — Finite difference time domain (FDTD) is a popular computational electrodynamics modeling technique. It is considered easy to understand and easy to implement in software. Since it is a time domain method, solutions can cover a wide frequency… …
36Jiffy (time) — This article discusses the word jiffy in the context of measuring time. For other uses, see Jiffy (disambiguation). Jiffy is an informal term for any unspecified short period of time, as in I ll be back in a jiffy . From this it has acquired a… …
37Doubling time — The doubling time is the period of time required for a quantity to double in size or value. It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many… …
38Discrete-time Fourier transform — In mathematics, the discrete time Fourier transform (DTFT) is one of the specific forms of Fourier analysis. As such, it transforms one function into another, which is called the frequency domain representation, or simply the DTFT , of the… …
39Real-time clock — A real time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are… …
40Real-time ridesharing — (also known as instant ridesharing, dynamic ridesharing, ad hoc ridesharing, or dynamic carpooling) is a service that arranges one time shared rides on very short notice.[1] This type of carpooling generally makes use of three recent… …
