51Submarine landslide — Submarine landslides are marine landslides that transport sediment across the continental shelf and into the deep ocean. A submarine landslide is initiated when the downwards driving stress (gravity and other factors) exceeds the resisting stress …
52Viscosity — For other uses, see Viscosity (disambiguation). Viscosity The substance above has lower viscosity than the substance below SI symbol: μ, η SI unit: Pa·s  …
53Double layer (plasma) — This article is about the structure in plasma physics. For other uses, see Double layer. Saturnian aurora whose reddish colour is characteristic of ionized hydrogen plasma.[1] Powered by the Saturnian equivalent of (filamentary) Birkeland… …
54Transverse isotropy — A transversely isotropic material is symmetric about an axis that is normal to a plane of isotropy. This transverse plane has infinite planes of symmetry and thus, within this plane, the material properties are same in all directions. With this… …
55Photonic crystal — The opal in this bracelet contains a natural periodic microstructure responsible for its iridescent color. It is essentially a natural photonic crystal, although it does not have a complete photonic band gap. Photonic crystals are periodic… …
56Olivia MFSK — Spectrogram (waterfall display) of an Olivia 16/500 signal centered on 7073.25KHz Olivia MFSK is an amateur radioteletype protocol designed to work in difficult (low signal to noise ratio plus multipath propagation) conditions on shortwave bands …
57Ionospheric absorption — (or ISAB) is the scientific name for absorption occurring as a result of the interaction between various types of electromagnetic waves and the free electrons in the ionosphere, which can interfere with radio transmissions.DescriptionIonosphere… …
58Thermal conduction — In heat transfer, conduction (or heat conduction) is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient. Conduction means collisional and diffusive transfer of kinetic energy of particles of ponderable …
59Surface wave — Diving grebe creates surface waves In physics, a surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities. A surface wave can also be an electromagnetic wave guided …
60Метод конечных разностей во временной области — (англ. Finite Difference Time Domain, FDTD)  один из наиболее популярных методов численной электродинамики, основанный на дискретизации уравнений Максвелла, записанных в дифференциальной форме. Содержание 1 Описание 2 Алгоритм Йи …
