Time constant — In physics and engineering, the time constant usually denoted by the Greek letter au , (tau), characterizes the frequency response of a first order, linear time invariant (LTI) system. Examples include electrical RC circuits and RL circuits. It… … Wikipedia
Time-variant system — A time variant system is a system, that is not time invariant(TIV). Overview There are many well developed techniques for dealing with the response of linear time invariant systems, such as Laplace and Fourier transforms. However, these… … Wikipedia

Time of Flight Ultrasonic Determination of 3D Elastic Constants — The three dimensional elastic constants of materials can be measured using the ultrasonic immersion method. This was pioneered by xx and xx from the National Physical Laboratory in the 19xx s. It has mainly been used for polymer composite… … Wikipedia
Time complexity — In computer science, the time complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the size of the input to the problem. The time complexity of an algorithm is commonly expressed using big O… … Wikipedia
Time — This article is about the measurement. For the magazine, see Time (magazine). For other uses, see Time (disambiguation). The flow of sand in an hourglass can be used to keep track of elapsed time. It also concretely represents the present as… … Wikipedia
Time.h — In the C and C++ programming languages, time.h (ctime is the recommended header file for C++ programs) is a header file defined in the C Standard Library to declare time and date functions that provide standardized access to time/date… … Wikipedia
Time-temperature superposition — The Time temperature superposition principle is a concept in polymer physics. [Hiemenz, Paul C., and Timothy P. Lodge. Polymer Chemistry. 2nd ed. Florida: Taylor Francis Group, 2007. 486 491.] [Li, Rongzhi. Time Temperature Superposition Method… … Wikipedia
Open-circuit time constant method — The open circuit time constant method is an approximate analysis technique used in electronic circuit design to determine the corner frequency of complex circuits. It also is known as the zero value time constant technique. The method provides a… … Wikipedia
RC time constant — In an RC circuit, the value of the time constant (in seconds) is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads), i.e. au = R × C . It is the time required to charge the capacitor, through the… … Wikipedia
