Distribution (mathematics)
Distributions, also known as Schwartz distributions are a kind of generalized function in mathematical analysis. Distributions make it possible to derivative, differentiate functions whose derivatives do not exist in the classical sense. In particular, any locally integrable function has a distributional derivative. Distributions are widely used in the theory of partial differential equations, where it may be easier to establish the existence of distributional solutions (weak solutions) than Solution of a differential equation, classical solutions, or where appropriate classical solutions may not exist. Distributions are also important in physics and engineering where many problems naturally lead to differential equations whose solutions or initial conditions are singular, such as the Dirac delta function, Dirac delta function. A Function (mathematics), function f is normally thought of as on the in the function Domain (function), domain by "sending" a point x in the domain t ...

Linux Distribution
A Linux distribution, often abbreviated as distro, is an operating system that includes the Linux kernel for its kernel functionality. Although the name does not imply product distribution per se, a distro—if distributed on its own—is often obtained via a website intended specifically for the purpose. Distros have been designed for a wide variety of systems ranging from personal computers (for example, Linux Mint) to servers (for example, Red Hat Enterprise Linux) and from embedded devices (for example, OpenWrt) to supercomputers (for example, Rocks Cluster Distribution). A distro typically includes many components in addition to the Linux kernel. Commonly, it includes a package manager, an init system (such as systemd, OpenRC, or runit), GNU tools and libraries, documentation, IP network configuration utilities, the getty TTY setup program, and many more. To provide a desktop experience (most commonly the Mesa userspace graphics drivers) a display server (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Probability Distribution
In probability theory and statistics, a probability distribution is a Function (mathematics), function that gives the probabilities of occurrence of possible events for an Experiment (probability theory), experiment. It is a mathematical description of a Randomness, random phenomenon in terms of its sample space and the Probability, probabilities of Event (probability theory), events (subsets of the sample space). For instance, if is used to denote the outcome of a coin toss ("the experiment"), then the probability distribution of would take the value 0.5 (1 in 2 or 1/2) for , and 0.5 for (assuming that fair coin, the coin is fair). More commonly, probability distributions are used to compare the relative occurrence of many different random values. Probability distributions can be defined in different ways and for discrete or for continuous variables. Distributions with special properties or for especially important applications are given specific names. Introduction A prob ...

Species Distribution
Species distribution, or species dispersion, is the manner in which a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with biological dispersal, dispersal, which is the movement of individuals away from their center of origin, region of origin or from a population center of high population density, density. Range In biology, the range of a species is the geographical area within which that species can be found. Within that range, distribution is the general structure of the species population, while dispersion is the variation in its population density. Range is often described with the foll ...

Companies Act 2006
The Companies Act 2006 (c. 46) is an act of the Parliament of the United Kingdom which forms the primary source of UK company law. The act was brought into force in stages, with the final provision being commenced on 1 October 2009. It largely superseded the Companies Act 1985. The act provides a comprehensive code of company law for the United Kingdom, and made changes to almost every facet of the law in relation to companies. The key provisions are: * the act codifies certain existing common law principles, such as those relating to directors' duties. * it transposes into UK law the Takeover Directive and the Transparency Directive of the European Union * it introduces various new provisions for private and public companies. * it applies a single company law regime across the United Kingdom, replacing the two separate (if identical) systems for Great Britain and Northern Ireland. * it otherwise amends or restates almost all of the Companies Act 1985 to varying degrees ...

Frequency Distribution
In statistics, the frequency or absolute frequency of an Event (probability theory), event i is the number n_i of times the observation has occurred/been recorded in an experiment or study. These frequencies are often depicted graphically or tabular form. Types The cumulative frequency is the total of the absolute frequencies of all events at or below a certain point in an ordered list of events. The Empirical probability, relative frequency (or ''empirical probability'') of an event is the absolute frequency Normalizing constant, normalized by the total number of events: : f_i = \frac = \frac. The values of f_i for all events i can be plotted to produce a frequency distribution. In the case when n_i = 0 for certain i, pseudocounts can be added. Depicting frequency distributions A frequency distribution shows a summarized grouping of data divided into mutually exclusive classes and the number of occurrences in a class. It is a way of showing unorganized data notably to sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distribution (differential Geometry)
In differential geometry, a discipline within mathematics, a distribution on a differentiable manifold, manifold M is an assignment x \mapsto \Delta_x \subseteq T_x M of vector subspaces satisfying certain properties. In the most common situations, a distribution is asked to be a vector subbundle of the tangent bundle TM. Distributions satisfying a further integrability condition give rise to foliations, i.e. partitions of the manifold into smaller submanifolds. These notions have several applications in many fields of mathematics, including integrable systems, Poisson geometry, Noncommutative geometry, non-commutative geometry, sub-Riemannian geometry, differential topology. Even though they share the same name, distributions presented in this article have nothing to do with distribution (mathematics), distributions in the sense of analysis. Definition Let M be a smooth manifold; a (smooth) distribution \Delta assigns to any point x \in M a vector subspace \Delta_x \subset T_xM ...

Spectral Power Distribution
In radiometry, photometry (optics), photometry, and color science, a spectral power distribution (SPD) measurement describes the Power (physics), power per unit area per unit wavelength of an illumination (lighting), illumination (radiant exitance). More generally, the term ''spectral power distribution'' can refer to the concentration, as a function of wavelength, of any radiometric or photometric quantity (e.g. radiant energy, radiant flux, radiant intensity, radiance, irradiance, radiant exitance, Radiosity (heat transfer), radiosity, luminance, luminous flux, luminous intensity, illuminance, luminous emittance). Knowledge of the SPD is crucial for optical-sensor system applications. Optical properties such as transmittance, reflectivity, and absorbance as well as the sensor response are typically dependent on the incident wavelength. Physics Mathematically, for the spectral power distribution of a radiant exitance or irradiance one may write: : M(\lambda)=\frac\approx\fra ...

Cosmopolitan Distribution
In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so. Killer whales ( orcas) are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between. Such a taxon (usually a species) is said to have a ''cosmopolitan'' distribution, or exhibit cosmopolitanism, as a species; another example, the rock dove (commonly referred to as a ' pigeon'), in addition to having been bred domestically for centuries, now occurs in most urban areas around the world. The extreme opposite of a cosmopolitan species is an endemic (native) species, or one foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distribution Of Wealth
The distribution of wealth is a comparison of the wealth of various members or groups in a society. It shows one aspect of economic inequality or heterogeneity in economics, economic heterogeneity. The distribution of wealth differs from the income distribution in that it looks at the Distribution (economics), economic distribution of ownership of the assets in a society, rather than the current income of members of that society. According to the International Association for Research in Income and Wealth, "the world distribution of wealth is much more unequal than that of income." For rankings regarding wealth, see list of countries by wealth equality or list of countries by wealth per adult. Definition of wealth Wealth of an individual is defined as net worth, expressed as: wealth = assets − liability (financial accounting), liabilities A broader definition of wealth, which is rarely used in the measurement of wealth inequality, also includes human capital. For example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributism
Distributism is an economic theory asserting that the world's productive assets should be widely owned rather than concentrated. Developed in the late 19th and early 20th centuries, distributism was based upon Catholic social teaching principles, especially those of Pope Leo XIII in his encyclical ''Rerum novarum'' (1891) and Pope Pius XI in ''Quadragesimo anno'' (1931). It has influenced Anglo Christian Democratic movements, and has been recognized as one of many influences on the social market economy. Distributism views ''laissez-faire'' capitalism and state socialism as equally flawed and exploitative, due to their extreme concentration of ownership. Instead, it favours small independent craftsmen and producers; or, if that is not possible, economic mechanisms such as cooperatives and member-owned mutual organization, mutual organisations, as well as Small and medium-sized enterprises, small to medium enterprises and vigorous competition law, anti-trust laws to restrain o ...

Distribution Resource Planning
{{Business logistics Distribution resource planning (DRP) is a method used in business administration for planning orders within a supply chain. DRP enables the user to set certain inventory control parameters (like a safety stock) and calculate the time-phased inventory requirements. This process is also commonly referred to as ''distribution requirements planning''. it consolidates the demands for multiple locations of several distribution centers with the sources of supply. DRP uses several variables: *the required quantity of product needed at the beginning of a period *the constrained quantity of product available at the beginning of a period *the recommended order quantity at the beginning of a period *the backordered demand at the end of a period *the on-hand inventory at the end of a period DRP needs the following information: *the demand in a future period *the scheduled receipts at the beginning of a period *the on-hand inventory at the beginning of a period *the safety ...
