Jules Dupuit
Arsène Jules Étienne Juvenel Dupuit (18 May 1804 – 5 September 1866) was an Italian-born French civil engineer and economist. He was born in Fossano, Italy then under the rule of Napoleon Bonaparte. At the age of ten he emigrated to France with his family where he studied in Versailles — winning a Physics prize at graduation. He then studied in the École Polytechnique as a civil engineer. He gradually took on more responsibility in various regional posts. He received a Légion d'honneur in 1843 for his work on the French road system, and shortly after moved to Paris. He also studied flood management in 1848 and supervised the construction of the Paris sewer system. He died in Paris. Engineering questions led to his interest in economics, a subject in which he was self-taught. His 1844 article was concerned with deciding the optimum toll for a bridge. It was here that he introduced his curve of diminishing marginal utility. As the quantity of a good consumed rises, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossano
Fossano ( pms, Fossan) is a town and ''comune'' of Piedmont, northern Italy. It is the fourth largest town of the Province of Cuneo, after Cuneo, Alba and Bra. It lies on the main railway line from Turin to Cuneo and to Savona, and has a branch line to Mondovì. Chief industries of the town include confectionery (with Italian industries Balocco and Maina), chemicals, metallurgy, and textiles. History Fossano appeared as a commune in 1236, founded by a Guelph league of cities, but in 1251 had to yield to Asti. In 1304 it was acquired by the Marquisate of Saluzzo. It finally surrendered in 1314 to Filippo d'Acaia, whose successor handed it over to the house of Savoy. Etymology The name Fossano could be the transformation of the name "locus" or "fundus faucianus", from the Roman first name Faucius, or derive from the word "fossato" (ditch), in Piedmontese "fossà ", from which "fossan" (inhabitant of the ditch).The sinkings are in fact characteristic of the hill on which the firs ...

Consumer Surplus
In mainstream economics, economic surplus, also known as total welfare or total social welfare or Marshallian surplus (after Alfred Marshall), is either of two related quantities: * Consumer surplus, or consumers' surplus, is the monetary gain obtained by consumers because they are able to purchase a product for a price that is less than the highest price that they would be willing to pay. * Producer surplus, or producers' surplus, is the amount that producers benefit by selling at a market price that is higher than the least that they would be willing to sell for; this is roughly equal to profit (since producers are not normally willing to sell at a loss and are normally indifferent to selling at a break-even price). Overview In the mid-19th century, engineer Jules Dupuit first propounded the concept of economic surplus, but it was the economist Alfred Marshall who gave the concept its fame in the field of economics. On a standard supply and demand diagram, consumer su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Ekelund
Robert Burton Ekelund Jr. (born 1940) is an American economist. Education Originally from Galveston, Texas, Ekelund attended St. Mary's University in San Antonio, Texas, earning his BBA in economics in 1962 and his MA in economics and history the next year. He was a member of the Order of the Barons and first worked as an instructor in economics while completing his master's degree. He then moved to Baton Rouge, Louisiana, to teach and continue his graduate work at Louisiana State University. He finished his PhD in economics and political theory there in 1967. His doctoral dissertation was on Jules Dupuit, a French civil engineer and economist. Ekelund would maintain this interest in Dupuit, making him the topic of a dozen journal articles and a 1999 book, ''Secret Origins of Modern Microeconomics: Dupuit and the Engineers''. Career In 1967, after the completion of his PhD, Ekelund was hired by Texas A&M University economics department. He was made Professor of Economics ...

Hydrogeologist
Hydrogeology (''hydro-'' meaning water, and ''-geology'' meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust (commonly in aquifers). The terms groundwater hydrology, geohydrology, and hydrogeology are often used interchangeably. Hydrogeology is the study of the laws governing the movement of subterranean water, the mechanical, chemical, and thermal interaction of this water with the porous solid, and the transport of energy, chemical constituents, and particulate matter by flow (Domenico and Schwartz, 1998). Groundwater engineering, another name for hydrogeology, is a branch of engineering which is concerned with groundwater movement and design of wells, pumps, and drains. The main concerns in groundwater engineering include groundwater contamination, conservation of supplies, and water quality.Walton, William C. (November 1990). ''Principles of Groundwater Engin ...

Hydrostatic
Fluid statics or hydrostatics is the branch of fluid mechanics that studies the condition of the equilibrium of a floating body and submerged body "fluids at hydrostatic equilibrium and the pressure in a fluid, or exerted by a fluid, on an immersed body". It encompasses the study of the conditions under which fluids are at rest in stable equilibrium as opposed to fluid dynamics, the study of fluids in motion. Hydrostatics is a subcategory of fluid statics, which is the study of all fluids, both compressible or incompressible, at rest. Hydrostatics is fundamental to hydraulics, the engineering of equipment for storing, transporting and using fluids. It is also relevant to geophysics and astrophysics (for example, in understanding plate tectonics and the anomalies of the Earth's gravitational field), to meteorology, to medicine (in the context of blood pressure), and many other fields. Hydrostatics offers physical explanations for many phenomena of everyday life, such as why ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Groundwater Flow Equation
Used in hydrogeology, the groundwater flow equation is the mathematical relationship which is used to describe the flow of groundwater through an aquifer. The transient flow of groundwater is described by a form of the diffusion equation, similar to that used in heat transfer to describe the flow of heat in a solid (heat conduction). The steady-state flow of groundwater is described by a form of the Laplace equation, which is a form of potential flow and has analogs in numerous fields. The groundwater flow equation is often derived for a small representative elemental volume (REV), where the properties of the medium are assumed to be effectively constant. A mass balance is done on the water flowing in and out of this small volume, the flux terms in the relationship being expressed in terms of head by using the constitutive equation called Darcy's law, which requires that the flow is laminar. Other approaches are based on Agent Based Models to incorporate the effect of complex aqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
