In complex geometry, a line through the origin in the direction of an isotropic vector is an isotropic line. Isotropic coordinates Isotropic coordinates are coordinates on an isotropic chart for Lorentzian manifolds. Isotropy group An isotropy group is the group of isomorphisms from any object to itself in a groupoid.
The equal sign refers to a reversible process, which is an imagined idealized theoretical limit, never actually occurring in physical reality, with essentially equal temperatures of system and surroundings. [10] [11] For an isentropic process, if also reversible, there is no transfer of energy as heat because the process is adiabatic; δQ = 0 ...
If the process depends only on | ′ |, the Euclidean distance (not the direction) between and ′, then the process is considered isotropic. A process that is concurrently stationary and isotropic is considered to be homogeneous; [8] in practice these properties reflect the differences (or rather the lack of them) in the behaviour of the ...
In probability theory, an isotropic measure is any mathematical measure that is invariant under linear isometries. It is a standard simplification and assumption used in probability theory. It is a standard simplification and assumption used in probability theory.
Isotropic formulations are thermodynamically stable microemulsions possessing lyotropic liquid crystal properties. [1] They inhabit a state of matter and physical behaviour somewhere between conventional liquids and that of solid crystals . [ 2 ]
Etching is a critically important process module in fabrication, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking material is a photoresist which has been patterned using photolithography.
In semiconductor manufacturing, isotropic etching is a method commonly used to remove material from a substrate via a chemical process using an etchant substance. The etchant may be in liquid-, gas- or plasma-phase, [1] although liquid etchants such as buffered hydrofluoric acid (BHF) for silicon dioxide etching are more often used.
In spatial statistics the theoretical variogram, denoted (,), is a function describing the degree of spatial dependence of a spatial random field or stochastic process (). ...
