41radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… …
42Corrosion fatigue — is fatigue in a corrosive environment. It is the mechanical degradation of a material under the joint action of corrosion and cyclic loading. Nearly all engineering structures experience some form of alternating stress, and are exposed to harmful …
43Speed of gravity — In the context of classical theories of gravitation, the speed of gravity refers to the speed at which a gravitational field propagates. This is the speed at which changes in the distribution of energy and momentum result in noticeable changes in …
44Supershear earthquake — A supershear earthquake is an earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave velocity. This causes a form of sonic boom to occur [ [http://news… …
45Earthquake — For other uses, see Earthquake (disambiguation). Global earthquake epicenters, 1963–1998 …
46Waveguide (electromagnetism) — In electromagnetics and communications engineering, the term waveguide may refer to any linear structure that guides electromagnetic waves. However, the original and most common meaning is a hollow metal pipe used for this purpose.A dielectric… …
47Single-wire transmission line — A single wire transmission line (or single wire method) is a method of supplying electrical power through a single wired electrical conductor. Single wire earth return (SWER) or single wire ground returns today supply single phase electrical… …
48Microbarom — In acoustics, microbaroms, also known as the voice of the sea ,[1][2] are a class of atmospheric infrasonic waves generated in marine storms[3][4] by a non linear interaction of ocean surface waves with the atmosphere …
49Dissipative soliton — Dissipative solitons (DSs) are stable solitary localized structures that arise in nonlinear spatially extended dissipative systems due to mechanisms of self organization. They can be considered as an extension of the classical soliton concept in… …
50Transmission line — This article is about the radio frequency transmission line. For the power transmission line, see electric power transmission. In communications and electronic engineering, a transmission line is a specialized cable designed to carry alternating… …
