Sun MicrosystemsSun Microsystems, Inc. (Sun for short), was an American technology company that sold computers, computer components, software, and information technology services and created the Java programming language, the Solaris operating system, ZFS, the (NFS), and SPARC microprocessors. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing. Notable Sun acquisitions include Cray Business Systems Division, Storagetek, and Innotek GmbH, creators of VirtualBox.
Severe weatherSevere weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. Types of severe weather phenomena vary, depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones.
Principle of maximum entropyThe principle of maximum entropy states that the probability distribution which best represents the current state of knowledge about a system is the one with largest entropy, in the context of precisely stated prior data (such as a proposition that expresses testable information). Another way of stating this: Take precisely stated prior data or testable information about a probability distribution function. Consider the set of all trial probability distributions that would encode the prior data.
National Weather ServiceThe National Weather Service (NWS) is an agency of the United States federal government that is tasked with providing weather forecasts, warnings of hazardous weather, and other weather-related products to organizations and the public for the purposes of protection, safety, and general information. It is a part of the National Oceanic and Atmospheric Administration (NOAA) branch of the Department of Commerce, and is headquartered in Silver Spring, Maryland, within the Washington metropolitan area.
Quotient ruleIn calculus, the quotient rule is a method of finding the derivative of a function that is the ratio of two differentiable functions. Let , where both f and g are differentiable and The quotient rule states that the derivative of h(x) is It is provable in many ways by using other derivative rules. Given , let , then using the quotient rule: The quotient rule can be used to find the derivative of as follows: Reciprocal rule The reciprocal rule is a special case of the quotient rule in which the numerator .
Chain ruleIn calculus, the chain rule is a formula that expresses the derivative of the composition of two differentiable functions f and g in terms of the derivatives of f and g. More precisely, if is the function such that for every x, then the chain rule is, in Lagrange's notation, or, equivalently, The chain rule may also be expressed in Leibniz's notation. If a variable z depends on the variable y, which itself depends on the variable x (that is, y and z are dependent variables), then z depends on x as well, via the intermediate variable y.
Mod (subculture)Mod, from the word modernist, is a subculture that began in London and spread throughout Great Britain and elsewhere, eventually influencing fashions and trends in other countries, and continues today on a smaller scale. Focused on music and fashion, the subculture has its roots in a small group of stylish London-based young men and women in the late 1950s who were termed modernists because they listened to modern jazz.
Garry's ModGarry's Mod is a 2006 sandbox game developed by Facepunch Studios and published by Valve. The base game mode of Garry's Mod has no set objectives and provides the player with a world in which to freely manipulate objects. Other game modes, notably Trouble in Terrorist Town and Prop Hunt, are created by other developers as mods and are installed separately, by means such as the Steam Workshop. Garry's Mod was created by Garry Newman as a mod for Valve's Source game engine and released in December 2004, before being expanded into a standalone release that was published by Valve in November 2006.
NASA wind turbinesStarting in 1975, NASA managed a program for the United States Department of Energy and the United States Department of Interior to develop utility-scale wind turbines for electric power, in response to the increase in oil prices. A number of the world's largest wind turbines were developed and tested under this pioneering program. The program was an attempt to leap well beyond the then-current state of the art of wind turbine generators, and developed a number of technologies later adopted by the wind turbine industry.
CyanogenModCyanogenMod (saɪˈænoʊdʒɛnmɒd ; CM) is a discontinued open-source operating system for mobile devices, based on the Android mobile platform. It was developed as free and open-source software based on the official releases of Android by Google, with added original and third-party code, and based on a rolling release development model. Although only a subset of total CyanogenMod users elected to report their use of the firmware, on 23 March 2015, some reports indicated that over 50 million people ran CyanogenMod on their phones.
Product ruleIn calculus, the product rule (or Leibniz rule or Leibniz product rule) is a formula used to find the derivatives of products of two or more functions. For two functions, it may be stated in Lagrange's notation as or in Leibniz's notation as The rule may be extended or generalized to products of three or more functions, to a rule for higher-order derivatives of a product, and to other contexts. Discovery of this rule is credited to Gottfried Leibniz, who demonstrated it using differentials. (However, J. M.
European College of NeuropsychopharmacologyThe European College of Neuropsychopharmacology (ECNP) is a pan-European, non-profit scientific association that serves as a platform to exchange and promote research in the field of neuropsychopharmacology. The ECNP “is committed to ensuring that advances in the understanding of brain function and human behaviour are translated into better treatments and enhanced public health”. The ECNP organises a number of activities to achieve this aim, such as a yearly congress, workshops, seminars, New Frontiers Meetings, publications, awards, supported talks and much more.
