https://en.wikipedia.org/wiki/Articulated%20robot | An articulated robot is a robot with rotary joints (e.g. a legged robot or an industrial robot). Articulated robots can range from simple two-jointed structures to systems with 10 or more interacting joints and materials.
They are powered by a variety of means, including electric motors.
Some types of robots, such as... |
https://en.wikipedia.org/wiki/Equilibrium%20thermodynamics | Equilibrium Thermodynamics is the systematic study of transformations of matter and energy in systems in terms of a concept called thermodynamic equilibrium. The word equilibrium implies a state of balance. Equilibrium thermodynamics, in origins, derives from analysis of the Carnot cycle. Here, typically a system, a... |
https://en.wikipedia.org/wiki/Thermodynamic%20state | In thermodynamics, a thermodynamic state of a system is its condition at a specific time; that is, fully identified by values of a suitable set of parameters known as state variables, state parameters or thermodynamic variables. Once such a set of values of thermodynamic variables has been specified for a system, the v... |
https://en.wikipedia.org/wiki/Shrimp%20on%20the%20barbie | "Shrimp on the barbie" is a phrase that originated in a series of television advertisements by the Australian Tourism Commission broadcast in the US and UK starring Paul Hogan from 1984 through to 1990. The full quote spoken by Hogan is "I'll slip an extra shrimp on the barbie for you", and the actual slogan of the ad ... |
https://en.wikipedia.org/wiki/Biological%20thermodynamics | Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy. The nonequilibrium thermodynami... |
https://en.wikipedia.org/wiki/Gramicidin%20S | Gramicidin S or Gramicidin Soviet is an antibiotic that is effective against some gram-positive and gram-negative bacteria as well as some fungi.
It is a derivative of gramicidin, produced by the gram-positive bacterium Brevibacillus brevis. Gramicidin S is a cyclodecapeptide, constructed as two identical pentapeptide... |
https://en.wikipedia.org/wiki/Synergetics%20%28Haken%29 | Synergetics is an interdisciplinary science explaining the formation and self-organization of patterns and structures in open systems far from thermodynamic equilibrium. It is founded by Hermann Haken, inspired by the laser theory. Haken's interpretation of the laser principles as self-organization of non-equilibrium s... |
https://en.wikipedia.org/wiki/Jock%20Tamson%27s%20bairns | "Jock Tamson's bairns" is a Scots (and Northumbrian English) dialect version of "Jack (John) Thomson's children" but both Jock and Tamson in this context take on the connotation of Everyman. The Dictionary of the Scots Language gives the following definitions:
Jock: (1) A generic term for a man, a male person. (34) Jo... |
https://en.wikipedia.org/wiki/Quasi-invariant%20measure | In mathematics, a quasi-invariant measure μ with respect to a transformation T, from a measure space X to itself, is a measure which, roughly speaking, is multiplied by a numerical function of T. An important class of examples occurs when X is a smooth manifold M, T is a diffeomorphism of M, and μ is any measure that l... |
https://en.wikipedia.org/wiki/Quasiconformal%20mapping | In mathematical complex analysis, a quasiconformal mapping, introduced by and named by , is a homeomorphism between plane domains which to first order takes small circles to small ellipses of bounded eccentricity.
Intuitively, let f : D → D′ be an orientation-preserving homeomorphism between open sets in the plane. I... |
https://en.wikipedia.org/wiki/Crossed%20product | In mathematics, and more specifically in the theory of von Neumann algebras, a crossed product
is a basic method of constructing a new von Neumann algebra from
a von Neumann algebra acted on by a group. It is related to
the semidirect product construction for groups. (Roughly speaking, crossed product is the expected... |
https://en.wikipedia.org/wiki/Tait%20conjectures | The Tait conjectures are three conjectures made by 19th-century mathematician Peter Guthrie Tait in his study of knots. The Tait conjectures involve concepts in knot theory such as alternating knots, chirality, and writhe. All of the Tait conjectures have been solved, the most recent being the Flyping conjecture.
