Low frequency — or LF refers to Radio Frequencies (RF) in the range of 30 kHz ndash;300 kHz. In Europe, and parts of Northern Africa and of Asia, part of the LF spectrum is used for AM broadcast service. In the western hemisphere, its main use is for aircraft… … Wikipedia
Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… … Wikipedia
Theoretical and experimental justification for the Schrödinger equation — The theoretical and experimental justification for the Schrödinger equation motivates the discovery of the Schrödinger equation, the equation that describes the dynamics of nonrelativistic particles. The motivation uses photons, which are… … Wikipedia
Radio-frequency identification — (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from… … Wikipedia
Cumulative frequency analysis — is the applcation of estimation theory to exceedance probability (or equivalently to its complement). The complement, the non exceedance probability concerns the frequency of occurrence of values of a phenomenon staying below a reference value.… … Wikipedia
