71Thermal power station — Republika Power Plant, a thermal power station in Pernik, Bulgaria …
72Lumped capacitance model — A lumped capacitance model, also called lumped system analysis,[1] reduces a thermal system to a number of discrete “lumps” and assumes that the temperature difference inside each lump is negligible. This approximation is useful to simplify… …
73Debye-Hückel equation — The Debye Hückel limiting law, named for its developers Peter Debye and Erich Hückel, provides one way to obtain activity coefficients Ref|Harris. Activities, rather than concentrations, are needed in many chemical calculations because solutions… …
74Non-line-of-sight propagation — Non line of sight (NLOS) or near line of sight is a term used to describe radio transmission across a path that is partially obstructed, usually by a physical object in the innermost Fresnel zone. Many types of radio transmissions depend, to… …
75TUBES ÉLECTRONIQUES — Les tubes électroniques sont des composants qui entrent dans la constitution de matériels électroniques très divers (émetteurs de radiodiffusion; émetteurs, récepteurs, caméras de télévision; équipements de télécommunications; radars; contre… …
76Debye–Hückel equation — The Debye–Hückel equation and Debye–Hückel limiting law, were derived by Peter Debye and Erich Hückel, who developed a theory with which to calculate activity coefficients of electrolyte solutions.[1] Activities, rather than concentrations, are… …
77Constantan — is a copper nickel alloy usually consisting of 55% copper and 45% nickel.[1] Also known as Eureka. Its main feature is its resistivity which is constant over a wide range of temperatures. Other alloys with similarly low temperature coefficients… …
78Uranium dioxide — Chembox new Name = Uranium dioxide ImageFile = UO2lattice.jpg IUPACName = Uranium dioxide Uranium(IV) oxide Section1 = Chembox Identifiers CASNo = 1344 57 6 Section2 = Chembox Properties Formula = UO2 MolarMass = 270 g/mol Solvent = other… …
79Thermal management of electronic devices and systems — Heat generated by electronic devices and circuitry must be dissipated to improve reliability and prevent premature failure. Techniques for heat dissipation can include heatsinks and fans for air cooling, and other forms of computer cooling such… …
