Gibbs Free Energy
In thermodynamics, the Gibbs free energy (or Gibbs energy; symbol G) is a thermodynamic potential that can be used to calculate the maximum amount of work that may be performed by a thermodynamically closed system at constant temperature and pressure. It also provides a necessary condition for processes such as chemical reactions that may occur under these conditions. The Gibbs free energy change , measured in joules in SI) is the ''maximum'' amount of non-expansion work that can be extracted from a closed system (one that can exchange heat and work with its surroundings, but not matter) at fixed temperature and pressure. This maximum can be attained only in a completely reversible process. When a system transforms reversibly from an initial state to a final state under these conditions, the decrease in Gibbs free energy equals the work done by the system to its surroundings, minus the work of the pressure forces. The Gibbs energy is the thermodynamic potential that is minim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibbs Phenomenon
In mathematics, the Gibbs phenomenon, discovered by Available on-line at:National Chiao Tung University: Open Course Ware: Hewitt & Hewitt, 1979. and rediscovered by , is the oscillatory behavior of the Fourier series of a piecewise continuously differentiable periodic function around a jump discontinuity. The function's Nth partial Fourier series (formed by summing its N lowest constituent sinusoids) produces large peaks around the jump which overshoot and undershoot the function's actual values. This approximation error approaches a limit of about 9% of the jump as more sinusoids are used, though the infinite Fourier series sum does eventually converge almost everywhere except the point of discontinuity. The Gibbs phenomenon was observed by experimental physicists, but was believed to be due to imperfections in the measuring apparatus, and it is one cause of ringing artifacts in signal processing. Description The Gibbs phenomenon involves both the fact that Fourier su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antony Gibbs & Sons
Antony Gibbs & Sons was a British trading company, established in London in 1802, whose interests spanned trading in cloth, guano, wine and fruit, and led to it becoming involved in banking, shipping and insurance. Having been family-owned via a partnership from its foundation, by the turn of the 20th century it was focused on banking and insurance. Floated on the London Stock Exchange in 1973, it was bought by HSBC in 1981 and formed the basis of its insurance broking arm, now part of global insurance company Marsh & McLennan. Background Antony Gibbs (1756–1816) from Clyst St Mary, Devon, was the fourth son of Dr. George Abraham Gibbs (1718–1794), who rose to be Chief Surgeon at the Royal Devon and Exeter Hospital. After leaving Exeter Grammar School, Antony was apprenticed to merchant Nicholas Brooke, whose firm traded with Spain exporting locally made woollen cloth. Brooke sent Anthony to Madrid, where he developed Spanish language skills, and an extensive personal network ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibbs Sampling
In statistics, Gibbs sampling or a Gibbs sampler is a Markov chain Monte Carlo (MCMC) algorithm for obtaining a sequence of observations which are approximated from a specified multivariate probability distribution, when direct sampling is difficult. This sequence can be used to approximate the joint distribution (e.g., to generate a histogram of the distribution); to approximate the marginal distribution of one of the variables, or some subset of the variables (for example, the unknown parameters or latent variables); or to compute an integral (such as the expected value of one of the variables). Typically, some of the variables correspond to observations whose values are known, and hence do not need to be sampled. Gibbs sampling is commonly used as a means of statistical inference, especially Bayesian inference. It is a randomized algorithm (i.e. an algorithm that makes use of random numbers), and is an alternative to deterministic algorithms for statistical inferenc ...

Gibbs Technologies
Alan Gibbs (born 1939) is a New Zealand-born businessman, entrepreneur and art collector. After a successful business career in New Zealand, which made him one of that country's wealthiest individuals, he relocated to London in 1999. He retains strong links to New Zealand through his development of Gibbs Farm, one of the world's leading sculpture parks. He is the founder of Gibbs Amphibians, based in Detroit, Michigan, Nuneaton, UK, and Auckland, New Zealand, which pioneers high-speed amphibious vehicle technologies. Early life Alan Gibbs was born in Christchurch, the son of Theodore Nisbet Gibbs and Elsie Gibbs. His father was an accountant, tax adviser and businessman. He was chairman of a 1951 Royal Commission on Taxation. The family moved to Wellington in 1947 and Alan attended Wadestown Primary School, Wellesley College and Wellington College. He undertook three out of four years of an engineering degree at Canterbury University, before switching to economics, completing a ...

Gibbs Paradox
In statistical mechanics, a semi-classical derivation of entropy that does not take into account the indistinguishability of particles yields an expression for entropy which is not extensive (is not proportional to the amount of substance in question). This leads to a paradox known as the Gibbs paradox, after Josiah Willard Gibbs, who proposed this thought experiment in 1874‒1875. The paradox allows for the entropy of closed systems to decrease, violating the second law of thermodynamics. A related paradox is the " mixing paradox". If one takes the perspective that the definition of entropy must be changed so as to ignore particle permutation, in the thermodynamic limit, the paradox is averted. Illustration of the problem Gibbs himself considered the following problem that arises if the ideal gas entropy is not extensive. Reprinted in and in Two identical containers of an ideal gas sit side-by-side. The gas in container #1 is identical in every respect to the gas in co ...

Gibbs & Cox
Gibbs & Cox is an American naval architecture firm that specializes in designing surface warships. Founded in 1922 in New York City, Gibbs & Cox is now headquartered in Arlington, Virginia. The firm has offices in New York City; Washington, D.C.; Newport News, Virginia; Philadelphia, Pennsylvania; and New Orleans, LA. In 2003, more than 150 warships built to the firm's designs, including 60 percent of the U.S. Navy's surface combatant fleet, were on active duty in nearly 20 navies. History The firm was founded as "Gibbs Brothers" by self-taught naval architect William Francis Gibbs and his brother Frederic H. Gibbs. The name was changed when architect Daniel H. Cox of Cox & Stevens joined the firm in 1929. In 1931, Gibbs & Cox designed the MV ''Savarona'', a large luxury yacht. According to company officials, more than 70 percent of U.S. tonnage launched during World War II was built to Gibbs & Cox designs. Ship types included destroyers, LST landing craft, minesweepers, tan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibbs College
Katharine Gibbs College was a for-profit institution of higher learning based in the United States of America, founded by Katharine Gibbs. As the Providence School in Rhode Island, it was founded in 1911 as an institution for the career education of young women.

Gibbs, Missouri
Gibbs is a village in Wilson Township, Adair County, Missouri, United States. The population was 107 at the 2010 census. History The town of Gibbs was an outgrowth of the Santa Fe Railroad, laid out in 1887 when the rail lines passed through southeastern Adair County. The name Gibbs was chosen in honor of Frank W. Gibbs, who donated land to the Santa Fe Railroad for the construction of a rail depot and stockyard. At the time of Gibbs' incorporation in 1894, it was anticipated that the town might become Adair County's main rail shipping point for the Santa Fe. This hope was bolstered by the fact that the road leading to Gibbs was the first all-weather road in the county. In the late 1800s a considerable amount of cattle and hogs were shipped from the Gibbs depot to packing houses in Chicago, along with seasonal carloads of fresh apples, strawberries, and eggs to points across America. Perrin & Company of Chicago also constructed a grain elevator trackside for the storage and sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibbs–Helmholtz Equation
The Gibbs–Helmholtz equation is a thermodynamic equation used for calculating changes in the Gibbs free energy of a system as a function of temperature. It was originally presented in an 1882 paper entitled " Die Thermodynamik chemischer Vorgange" by Hermann von Helmholtz. It describes how the Gibbs free energy, which was presented originally by Josiah Willard Gibbs, varies with temperature. The equation is:Physical chemistry, P. W. Atkins, Oxford University Press, 1978, where ''H'' is the enthalpy, ''T'' the absolute temperature and ''G'' the Gibbs free energy of the system, all at constant pressure ''p''. The equation states that the change in the ''G/T'' ratio at constant pressure as a result of an infinitesimally small change in temperature is a factor ''H/T''2. Chemical reactions and work The typical applications of this equation are to chemical reactions. The equation reads: :\left( \frac \right)_p = - \frac with Δ''G'' as the change in Gibbs energy due to rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
