Lorenz System
The Lorenz system is a system of ordinary differential equations first studied by mathematician and meteorologist Edward Lorenz. It is notable for having chaotic solutions for certain parameter values and initial conditions. In particular, the Lorenz attractor is a set of chaotic solutions of the Lorenz system. In popular media the " butterfly effect" stems from the real-world implications of the Lorenz attractor, namely that in a chaotic physical system, in the absence of perfect knowledge of the initial conditions (even the minuscule disturbance of the air due to a butterfly flapping its wings), our ability to predict its future course will always fail. This underscores that physical systems can be completely deterministic and yet still be inherently unpredictable. The shape of the Lorenz attractor itself, when plotted in phase space, may also be seen to resemble a butterfly. Overview In 1963, Edward Lorenz, with the help of Ellen Fetter who was responsible for the numerical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lorenz Gauge Condition
In electromagnetism, the Lorenz gauge condition or Lorenz gauge, for Ludvig Lorenz, is a partial gauge fixing of the electromagnetic vector potential by requiring \partial_\mu A^\mu = 0. The name is frequently confused with Hendrik Lorentz, who has given his name to many concepts in this field. The condition is Lorentz invariant. The condition does not completely determine the gauge: one can still make a gauge transformation A^\mu \to A^\mu + \partial^\mu f, where \partial^\mu is the four-gradient and f is a harmonic scalar function (that is, a scalar function satisfying \partial_\mu\partial^\mu f = 0, the equation of a massless scalar field). The Lorenz condition is used to eliminate the redundant spin-0 component in the representation theory of the Lorentz group. It is equally used for massive spin-1 fields where the concept of gauge transformations does not apply at all. Description In electromagnetism, the Lorenz condition is generally used in calculations of time-depen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lorenz Curve
In economics, the Lorenz curve is a graphical representation of the distribution of income or of wealth. It was developed by Max O. Lorenz in 1905 for representing inequality of the wealth distribution. The curve is a graph showing the proportion of overall income or wealth assumed by the bottom ''x''% of the people, although this is not rigorously true for a finite population (see below). It is often used to represent income distribution, where it shows for the bottom ''x''% of households, what percentage (''y''%) of the total income they have. The percentage of households is plotted on the ''x''-axis, the percentage of income on the ''y''-axis. It can also be used to show distribution of assets. In such use, many economists consider it to be a measure of social inequality. The concept is useful in describing inequality among the size of individuals in ecology and in studies of biodiversity, where the cumulative proportion of species is plotted against the cumulative proportio ...

Lorenz Cipher
The Lorenz SZ40, SZ42a and SZ42b were German rotor stream cipher machines used by the German Army during World War II. They were developed by C. Lorenz AG in Berlin. The model name ''SZ'' was derived from ''Schlüssel-Zusatz'', meaning ''cipher attachment''. The instruments implemented a Vernam stream cipher. British cryptanalysts, who referred to encrypted German teleprinter traffic as ''Fish'', dubbed the machine and its traffic ''Tunny'' (meaning tunafish) and deduced its logical structure three years before they saw such a machine. The SZ machines were in-line attachments to standard teleprinters. An experimental link using SZ40 machines was started in June 1941. The enhanced SZ42 machines were brought into substantial use from mid-1942 onwards for high-level communications between the German High Command in Wünsdorf close to Berlin, and Army Commands throughout occupied Europe. The more advanced SZ42A came into routine use in February 1943 and the SZ42B in June 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lorenz Beam
The Lorenz beam was a blind-landing radio navigation system developed by C. Lorenz AG in Berlin. The first system had been installed in 1932 at Berlin-Tempelhof Central Airport, followed by Dübendorf in Switzerland (1934) and others all over the world. The Lorenz company referred to it simply as the ''Ultrakurzwellen-Landefunkfeuer'', German for "ultra-short-wave landing radio beacon", or ''LFF''. In the UK it was known as ''Standard Beam Approach'' (SBA). Prior to the start of the Second World War the Germans deployed the system at many Luftwaffe airfields in and outside Germany and equipped most of their bombers with the radio equipment needed to use it. It was also adapted into versions with much narrower and longer-range beams that was used to guide the bombers on missions over Britain, under the name Knickebein and X-Gerät. Beam navigation provides a single line in space, making it useful for landing or enroute navigation, but not as a general purpose navigation system that a ...

Lorenz Publishing
The Lorenz Corporation, previously known as Lorenz Publishing Company, is a music publisher located in Dayton, Ohio, United States. It is best known for its publication of church music Church music is Christian music written for performance in church, or any musical setting of ecclesiastical liturgy, or music set to words expressing propositions of a sacred nature, such as a hymn. History Early Christian music The onl ... for smaller congregations served by amateur musicians. It also publishes other varieties of music and general education materials. History The company was founded by E.S. Lorenz in 1890 and has been under the management of E.S. Lorenz and his descendants since that time. The idea came in 1889 "when he had compiled a hymnal for the United Brethren Publishing House located in downtown Dayton." In the 1970s and 1980s, the company changed its name to Lorenz Industries, and then The Lorenz Corporation. Reiff Lorenz, a great great grandson of the founder ...

Lorenz Rifle
The Lorenz rifle was an Austrian rifle used in the mid 19th century. It was used in the Second Italian War of Independence in 1859 and the Austro-Prussian War in 1866, and also featured prominently in the American Civil War. History The Lorenz rifle was designed by Austrian lieutenant Joseph Lorenz. It was first approved for manufacture in 1854, and was Austria's first all-new infantry firearm since 1842. The demand for the rifles was much greater than what the Austrian state arsenals could produce, so much of the production was done by private manufacturers. Many of these manufacturers did not have the skill and precision required to make what was then a very modern and sophisticated rifle design, and as a result, the quality of Lorenz rifles varied quite a bit. The bore diameters also varied quite a bit due to insufficient control of allowable tolerances. This often left too much of a gap between the bullet and the barrel, resulting in poor performance.
