81Leaky mode — A leaky mode or tunneling mode in an optical fiber or other waveguide is a mode having an electric field that decays monotonically for a finite distance in the transverse direction but becomes oscillatory everywhere beyond that finite distance.… …
82Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… …
83RLC circuit — A series RLC circuit: a resistor, inductor, and a capacitor An RLC circuit (or LCR circuit) is an electrical circuit consisting of a resistor, an inductor, and a capacitor, connected in series or in parallel. The RLC part of the name is due to… …
84Ultimate fate of the universe — The ultimate fate of the universe is a topic in physical cosmology. Many possible fates are predicted by rival scientific theories, including futures of both finite and infinite duration. Once the notion that the universe started with a Big Bang… …
85Transmission electron microscopy — A TEM image of the polio virus. The polio virus is 30 nm in size.[1] Transmission electron microscopy (TEM) is a microscopy technique whereby a beam of electrons is transmitted through an ultra thin specimen, interacting with the specimen as it… …
86List of Tesla patents — Below is a list of Tesla patents. Dr. Nikola Tesla was an inventor who obtained around 300 patents [Snezana Sarbo, [http://www.tesla symp06.org/papers/Tesla Symp06 Sarboh.pdfNikola Tesla s Patents] , Sixth International Symposium Nikola Tesla,… …
87Mechanical ventilation — In architecture and climate control, mechanical or forced ventilation is the use of powered equipment, e.g. fans and blowers, to move air  see ventilation (architecture). Mechanical ventilation Intervention …
88Gene regulatory network — A gene regulatory network (also called a GRN or genetic regulatory network ) is a collection of DNA segments in a cell which interact with each other (indirectly through their RNA and protein expression products) and with other substances in the… …
89Path integral formulation — This article is about a formulation of quantum mechanics. For integrals along a path, also known as line or contour integrals, see line integral. The path integral formulation of quantum mechanics is a description of quantum theory which… …
90List of IEC standards — In order to distinguish standards published by the International Electrotechnical Commission numerically from other international standards, their number range was shifted in 1997 by adding 60000. So what used to be called IEC 27 is now… …
