Radial keratotomy (RK) is a refractive surgical procedure to correct myopia (nearsightedness). It was developed in 1974 by Svyatoslav Fyodorov , a Russian ophthalmologist . It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy , LASIK , Epi-LASIK and the phakic intraocular lens .
Runge–Kutta methods are methods for the numerical solution of the ordinary differential equation. Explicit Runge–Kutta methods take the form. Stages for implicit methods of s stages take the more general form, with the solution to be found over all s. Each method listed on this page is defined by its Butcher tableau, which puts the ...
t. e. In numerical analysis, the Runge–Kutta methods (English: / ˈrʊŋəˈkʊtɑː / ⓘ RUUNG-ə-KUUT-tah[1]) are a family of implicit and explicit iterative methods, which include the Euler method, used in temporal discretization for the approximate solutions of simultaneous nonlinear equations. [2]
The 26 cm RK L/20 was a gun from a family of Krupp naval artillery guns designed in the late 1860s. The gun resembled the 26 cm RK L/22, but was shorter, so it could be used in the central battery of certain ships. The gun came in an early variant with a 260 mm caliber. Later, these guns were adapted to 263 mm caliber.
Cheque Truncation System (CTS) or Image-based Clearing System (ICS), in India, is a project of the Reserve Bank of India (RBI), commenced in 2010, for faster clearing of cheques. [1] CTS is based on a cheque truncation or online image-based cheque clearing system where cheque images and magnetic ink character recognition (MICR) data are ...

SABIO-RK (S ystem for the A nalysis of Bio chemical Pathways - R eaction K inetics) is a web-accessible database storing information about biochemical reactions and their kinetic properties. SABIO-RK comprises a reaction-oriented representation of quantitative information on reaction dynamics based on a given selected publication.
In physics and thermodynamics, the Redlich–Kwong equation of state is an empirical, algebraic equation that relates temperature, pressure, and volume of gases. It is generally more accurate than the van der Waals equation and the ideal gas equation at temperatures above the critical temperature. It was formulated by Otto Redlich and Joseph ...
