Also around 1791 de Prony was working on geometry with Pierre Girard . Then in 1792, de Prony began a major task of producing logarithmic and trigonometric tables, the Cadastre. With the assistance of Legendre Carnot and other mathematicians, and between 70 to 80 assistants, the work was undertaken over a period of years, being completed in 1801. The tables were, see [2]:- ... vast, with values calculated to between fourteen and twenty-nine decimal places. Each copy consisted of eighteen folio volumes together with another volume of mathematical procedures. Getting such a massive work published was another matter. Negotiations went on over a number of years until , in 1809, it seemed they would appear.

Extractions: I-lis career may be studied in Hesiod; in the splendid Prometheus vinctus of Aeschylus, with the scholia; in Heynes Apollodorus; in the excursus (I) of SchUzius to the Aeschylean drama, and in the frequently quoted work of Kuhn. The essay of Steinthal may also be examined (Goldziher, Myth. Hebr., Eng. trans., p. 363392), where the amused student will discover that Moses is a Pramanthas, with much else that is as learned and convincing. See also Tylors Early History of Man; Nesfield in Calcutta Review (January, April, 1884); and the article FIRE. (A. L.) PROMOTER, one who promotes (Lat. promovere, to move forward), advances or forwards any scheme, project or undertaking. The most general specific sense in which the word is now used is that of a person who takes the steps necessary to the incorporation of a joint-stock company (see COMPANY) or to the passing of a private or local act of parliament. In legal history, a promoter was one who prosecuted offenders, originally as an officer of the Crown, later as a common informer; the term is still used thus of the prosecutor in a suit in an ecclesiastical court. PRONGBUCK, PRONGHORN, or (in America) simply ANTELOPE, the sole existing representative of a family (Antilocapridae) of hollow-horned ruminants in which the horn-sheaths are forked and annually shed and renewed. Standing about 3 ft. high at the shoulder and slightly more at the croup, the male prongbuck has the black horns rising vertically upwards immediately above the eyes. The general colour is bright sandy fawn, with much white on the face, three white bars on the throat and white under parts and buttocks. The white throat-bands are evidently protective; and the long white hair on the buttocks can be erected and expanded into large chrysanthemum-like bunches as in Japanese deer; these being guides to the members of the herd vJhen in flight. The tail is short; lateral hoofs are wanting; and the teeth are tall-crowned. Female prongbuck produce one or two young at a birth, and are either hornless or furnished with small and more or less rudimentary horns.

Extractions: onde c, d e e são coeficientes empíricos para um dado tipo de tubo. Darcy desta forma introduziduziu o conceito de coeficiente de atrito escalonado por diâmetro; o que nós atualmente chamamos de rugosidade relativa, quando aplicando o Diagrama do Moody. Portanto, é tradicional chamar f de "fator f de Darcy", ainda que Darcy nunca tenha proposto isto naquela fórmula. Os dois conceitos foram juntados por Fanning em 1880 (eu penso). Ele publicou uma compilação dos valores de f como uma função do tipo de tub e da velocidade. Contudo, seria notado que Fanning utilizou o raio hidráulico, ao invés de D na equação do atrito, e assim os valores do "f de Fanning" são apenas 1/4 dos valores do "f de Darcy". A equação de Darcy-Weisbach não foi universalmente proveitosa até o desenvolvimento do diagrama de Moody Christensen, B.A., 2000.

Introduction Least Squares Prony's Method Modified Prony Methods Real Exponential Fitting Frequency Estimation Articles Software Links Note that you need the symbol font installed on your browser to read the mathematical equations below correctly Many functions, used to model physical systems in engineering or physics, arise as the solution to a homogeneous differential equation. Let µ(t) be the concentration or intensity of the physical process at time t. It is often the case that there are physical reasons for supposing that µ(t) satisfies a differential equation like S p+1 x k D k-1 µ(t) = for all t k=1 where D is the differential operator and the x k are unknown coefficients. A typical solution to (1) is a sum of exponential functions (2) µ(t) = S p a j exp( b j t) j=1 where the b j are rate constants (usually negative) and the a j are amplitudes. Such a solution is appropriate for a transient system which dies to zero as time goes on, such as the concentration of an intermediary compound in a chemical reaction. Another typical solution to (1) is a sum of sinusoids (3) µ(t) = S p/2 a j sin( b j t + f j j=1 Such a solution is persistent and periodic, and is appropriate for electrical or physical systems driven by persistent regular oscillating forces. Signals in speech recognition are often of this type. A third common solution is the damped sinusoid
