1 structured systems analysis and design method
Gen Mgta technique for the analysis and design of computer systems. The structured systems analysis and design method was developed by the Central Computer and Telecommunications Agency in the United Kingdom in the early 1980s. The technique adopts a structured methodology toward systems development through the use of data flow, logical data, and entity event modeling. Core development stages include: feasibility study; requirements analysis; requirements specification; logical system specification; and physical design. All the steps and tasks within each stage must be complete before subsequent stages can begin.Abbr. SSADMThe ultimate business dictionary > structured systems analysis and design method

2 Monte Carlo method
Gen Mgta statistical technique used in business decision making that involves a number of uncertain variables, such as capital investment and resource allocation. The name of the Monte Carlo method derives from the use of random numbers as generated by a roulette wheel. The numbers are used in repeated simulations, often performed by spreadsheet programs on computers, to calculate a variety of possible outcomes. The technique was developed by mathematicians in the early 1960s for use in nuclear physics and operational research but has since been used more widely. -

8 Coolidge, William David
[br]b. 23 October 1873 Hudson, Massachusetts, USAd. 3 February 1975 New York, USA[br]American physicist and metallurgist who invented a method of producing ductile tungsten wire for electric lamps.[br]Coolidge obtained his BS from the Massachusetts Institute of Technology (MIT) in 1896, and his PhD (physics) from the University of Leipzig in 1899. He was appointed Assistant Professor of Physics at MIT in 1904, and in 1905 he joined the staff of the General Electric Company's research laboratory at Schenectady. In 1905 Schenectady was trying to make tungsten-filament lamps to counter the competition of the tantalum-filament lamps then being produced by their German rival Siemens. The first tungsten lamps made by Just and Hanaman in Vienna in 1904 had been too fragile for general use. Coolidge and his life-long collaborator, Colin G. Fink, succeeded in 1910 by hot-working directly dense sintered tungsten compacts into wire. This success was the result of a flash of insight by Coolidge, who first perceived that fully recrystallized tungsten wire was always brittle and that only partially work-hardened wire retained a measure of ductility. This grasped, a process was developed which induced ductility into the wire by hot-working at temperatures below those required for full recrystallization, so that an elongated fibrous grain structure was progressively developed. Sintered tungsten ingots were swaged to bar at temperatures around 1,500°C and at the end of the process ductile tungsten filament wire was drawn through diamond dies around 550°C. This process allowed General Electric to dominate the world lamp market. Tungsten lamps consumed only one-third the energy of carbon lamps, and for the first time the cost of electric lighting was reduced to that of gas. Between 1911 and 1914, manufacturing licences for the General Electric patents had been granted for most of the developed work. The validity of the General Electric monopoly was bitterly contested, though in all the litigation that followed, Coolidge's fibering principle was upheld. Commercial arrangements between General Electric and European producers such as Siemens led to the name "Osram" being commonly applied to any lamp with a drawn tungsten filament. In 1910 Coolidge patented the use of thoria as a particular additive that greatly improved the high-temperature strength of tungsten filaments. From this development sprang the technique of "dispersion strengthening", still being widely used in the development of high-temperature alloys in the 1990s. In 1913 Coolidge introduced the first controllable hot-cathode X-ray tube, which had a tungsten target and operated in vacuo rather than in a gaseous atmosphere. With this equipment, medical radiography could for the first time be safely practised on a routine basis. During the First World War, Coolidge developed portable X-ray units for use in field hospitals, and between the First and Second World Wars he introduced between 1 and 2 million X-ray machines for cancer treatment and for industrial radiography. He became Director of the Schenectady laboratory in 1932, and from 1940 until 1944 he was Vice-President and Director of Research. After retirement he was retained as an X-ray consultant, and in this capacity he attended the Bikini atom bomb trials in 1946. Throughout the Second World War he was a member of the National Defence Research Committee.[br]Bibliography1965, "The development of ductile tungsten", Sorby Centennial Symposium on the History of Metallurgy, AIME Metallurgy Society Conference, Vol. 27, ed.

9 Paul, Lewis
SUBJECT AREA: Textiles[br]d. April 1759 Brook Green, London, England[br]English inventor of hand carding machines and partner with Wyatt in early spinning machines.[br]Lewis Paul, apparently of French Huguenot extraction, was quite young when his father died. His father was Physician to Lord Shaftsbury, who acted as Lewis Paul's guardian. In 1728 Paul made a runaway match with a widow and apparently came into her property when she died a year later. He must have subsequently remarried. In 1732 he invented a pinking machine for making the edges of shrouds out of which he derived some profit.Why Paul went to Birmingham is unknown, but he helped finance some of Wyatt's earlier inventions. Judging by the later patents taken out by Paul, it is probable that he was the one interested in spinning, turning to Wyatt for help in the construction of his spinning machine because he had no mechanical skills. The two men may have been involved in this as early as 1733, although it is more likely that they began this work in 1735. Wyatt went to London to construct a model and in 1736 helped to apply for a patent, which was granted in 1738 in the name of Paul. The patent shows that Paul and Wyatt had a number of different ways of spinning in mind, but contains no drawings of the machines. In one part there is a description of sets of rollers to draw the cotton out more finely that could have been similar to those later used by Richard Arkwright. However, it would seem that Paul and Wyatt followed the other main method described, which might be called spindle drafting, where the fibres are drawn out between the nip of a pair of rollers and the tip of the spindle; this method is unsatisfactory for continuous spinning and results in an uneven yarn.The spinning venture was supported by Thomas Warren, a well-known Birmingham printer, Edward Cave of Gentleman's Magazine, Dr Robert James of fever-powder celebrity, Mrs Desmoulins, and others. Dr Samuel Johnson also took much interest. In 1741 a mill powered by two asses was equipped at the Upper Priory, Birmingham, with, machinery for spinning cotton being constructed by Wyatt. Licences for using the invention were sold to other people including Edward Cave, who established a mill at Northampton, so the enterprise seemed to have great promise. A spinning machine must be supplied with fibres suitably prepared, so carding machines had to be developed. Work was in hand on one in 1740 and in 1748 Paul took out another patent for two types of carding device, possibly prompted by the patent taken out by Daniel Bourn. Both of Paul's devices were worked by hand and the carded fibres were laid onto a strip of paper. The paper and fibres were then rolled up and placed in the spinning machine. In 1757 John Dyer wrote a poem entitled The Fleece, which describes a circular spinning machine of the type depicted in a patent taken out by Paul in 1758. Drawings in this patent show that this method of spinning was different from Arkwright's. Paul endeavoured to have the machine introduced into the Foundling Hospital, but his death in early 1759 stopped all further development. He was buried at Paddington on 30 April that year.[br]Bibliography1738, British patent no. 562 (spinning machine). 1748, British patent no. 636 (carding machine).1758, British patent no. 724 (circular spinning machine).Further ReadingG.J.French, 1859, The Life and Times of Samuel Crompton, London, App. This should be read in conjunction with R.L.Hills, 1970, Power in the Industrial Revolution, Manchester, which shows that the roller drafting system on Paul's later spinning machine worked on the wrong principles.A.P.Wadsworth and J.de L.Mann, 1931, The Cotton Trade and Industrial Lancashire, 1600–1780, Manchester (provides good coverage of the partnership of Paul and Wyatt and the early mills).E.Baines, 1835, History of the Cotton Manufacture in Great Britain, London (this publication must be mentioned, but is now out of date).A.Seymour-Jones, 1921, "The invention of roller drawing in cotton spinning", Transactions of the Newcomen Society 1 (a more modern account).RLH -
10 Zeiss, Carl
SUBJECT AREA: Photography, film and optics[br]b. 11 September 1816 Weimar, Thuringia, Germanyd. 3 December 1888 Jena, Saxony, Germany[br]German lens manufacturer who introduced scientific method to the production of compound microscopes and made possible the production of the first anastigmatic photographic objectives.[br]After completing his early education in Weimar, Zeiss became an apprentice to the engineer Dr Frederick Koerner. As part of his training, Zeiss was required to travel widely and he visited Vienna, Berlin, Stuttgart and Darmstadt to study his trade. In 1846 he set up a business of his own, an optical workshop in Jena, where he began manufacturing magnifying glasses and microscopes. Much of his work was naturally for the university there and he had the co-operation of some of the University staff in the development of precision instruments. By 1858 he was seeking to make more expensive compound microscopes, but he found the current techniques primitive and laborious. He decided that it was necessary to introduce scientific method to the design of the optics, and in 1866 he sought the advice of a professor of physics at the University of Jena, Ernst Abbe (1840–1905). It took Zeiss until 1869 to persuade Abbe to join his company, and two difficult years were spent working on the calculations before success was achieved. Within a few more years the Zeiss microscope had earned a worldwide reputation for quality. Abbe became a full partner in the Zeiss business in 1875. In 1880 Abbe began an association with Friedrich Otte Schott that was to lead to the establishment of the famous Jena glass works in 1884. With the support of the German government, Jena was to become the centre of world production of new optical glasses for photographic objectives.In 1886 the distinguished mathematician and optician Paul Rudolph joined Zeiss at Jena. After Zeiss's death, Rudolph went on to use the characteristics of the new glass to calculate the first anastigmatic lenses. Immediately successful and widely imitated, the anastigmats were also the first of a long series of Zeiss photographic objectives that were to be at the forefront of lens design for years to come. Abbe took over the management of the company and developed it into an internationally famous organization.[br]Further ReadingL.W.Sipley, 1965, Photography's Great Inventors, Philadelphia (a brief biography).

11 Hopkinson, John
[br]b. 27 July 1849 Manchester, Englandd. 27 August 1898 Petite Dent de Veisivi, Switzerland[br]English mathematician and electrical engineer who laid the foundations of electrical machine design.[br]After attending Owens College, Manchester, Hopkinson was admitted to Trinity College, Cambridge, in 1867 to read for the Mathematical Tripos. An appointment in 1872 with the lighthouse department of the Chance Optical Works in Birmingham directed his attention to electrical engineering. His most noteworthy contribution to lighthouse engineering was an optical system to produce flashing lights that distinguished between individual beacons. His extensive researches on the dielectric properties of glass were recognized when he was elected to a Fellowship of the Royal Society at the age of 29. Moving to London in 1877 he became established as a consulting engineer at a time when electricity supply was about to begin on a commercial scale. During the remainder of his life, Hopkinson's researches resulted in fundamental contributions to electrical engineering practice, dynamo design and alternating current machine theory. In making a critical study of the Edison dynamo he developed the principle of the magnetic circuit, a concept also arrived at by Gisbert Kapp around the same time. Hopkinson's improvement of the Edison dynamo by reducing the length of the field magnets almost doubled its output. In 1890, in addition to-his consulting practice, Hopkinson accepted a post as the first Professor of Electrical Engineering and Head of the Siemens laboratory recently established at King's College, London. Although he was not involved in lecturing, the position gave him the necessary facilities and staff and student assistance to continue his researches. Hopkinson was consulted on many proposals for electric traction and electricity supply, including schemes in London, Manchester, Liverpool and Leeds. He also advised Mather and Platt when they were acting as contractors for the locomotives and generating plant for the City and South London tube railway. As early as 1882 he considered that an ideal method of charging for the supply of electricity should be based on a two-part tariff, with a charge related to maximum demand together with a charge for energy supplied. Hopkinson was one the foremost expert witnesses of his day in patent actions and was himself the patentee of over forty inventions, of which the three-wire system of distribution and the series-parallel connection of traction motors were his most successful. Jointly with his brother Edward, John Hopkinson communicated the outcome of his investigations to the Royal Society in a paper entitled "Dynamo Electric Machinery" in 1886. In this he also described the later widely used "back to back" test for determining the characteristics of two identical machines. His interest in electrical machines led him to more fundamental research on magnetic materials, including the phenomenon of recalescence and the disappearance of magnetism at a well-defined temperature. For his work on the magnetic properties of iron, in 1890 he was awarded the Royal Society Royal Medal. He was a member of the Alpine Club and a pioneer of rock climbing in Britain; he died, together with three of his children, in a climbing accident.[br]Principal Honours and DistinctionsFRS 1878.

SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 13 January 1847 Memmingen, Bavaria, Germanyd. 27 August 1932 Moylan, Pennsylvania, USA[br]German (naturalized American) mechanical engineer, inventor of bevel-gear generator and economist.[br]Hugo Bilgram studied mechanical engineering at the Augsburg Maschinenbau Schule and graduated in 1865. He worked as a machinist and draughtsman for several firms in Germany before going to the United States in 1869.In America he first worked for L.B.Flanders Company and Southwark Foundry \& Machine Company in Philadelphia, designing instruments and machines. In the 1870s he also assisted in an evening class in drawing at The Franklin Institute. He devised the Bilgram Valve Diagram for analysing the action of steam engine slide valves and he developed a method of drawing accurate outlines of gear teeth. This led him to design a machine for cutting the teeth of gear wheels, particularly bevel wheels, which he patented in 1884. He was in charge of the American branch of Brehmer Brothers Company from 1879 and in 1884 became the sole owner of the company, which was later incorporated as the Bilgram Machine Works. He was responsible for several other inventions and developments in gear manufacture.Bilgram was a member of the Franklin Institute, the American Academy of Political and Social Science, the Philadelphia Technische Verein and the Philadelphia Engineer's Club, and was elected a member of the American Society of Mechanical Engineers in 1885. He was also an amateur botanist, keenly interested in microscopic work.[br]Principal Honours and DistinctionsFranklin Institute Elliott Cresson Gold Medal.

13 Cotton, William
SUBJECT AREA: Textiles[br]b. 1819 Seagrave, Leicestershire, Englandd. after 1878[br]English inventor of a power-driven flat-bed knitting machine.[br]Cotton was originally employed in Loughborough and became one of the first specialized hosiery-machine builders. After the introduction of the latch needle by Matthew Townsend in 1856, knitting frames developed rapidly. The circular frame was easier to work automatically, but attempts to apply power to the flat frame, which could produce fully fashioned work, culminated in 1863 with William Cotton's machine. In that year he invented a machine that could make a dozen or more stockings or hose simultaneously and knit fashioned garments of all kinds. The difficulty was to reduce automatically the number of stitches in the courses where the hose or garment narrowed to give it shape. Cotton had early opportunities to apply himself to the improvement of hosiery machines while employed in the patent shop of Cartwright \& Warner of Loughborough, where some of the first rotaries were made. He remained with the firm for twenty years, during which time sixty or seventy of these machines were turned out. Cotton then established a factory for the manufacture of warp fabrics, and it was here that he began to work on his ideas. He had no knowledge of the principles of engineering or drawing, so his method of making sketches and then getting his ideas roughed out involved much useless labour. After twelve years, in 1863, a patent was issued for the machine that became the basis of the Cotton's Patent type. This was a flat frame driven by rotary mechanism and remarkable for its adaptability. At first he built his machine upright, like a cottage piano, but after much thought and experimentation he conceived the idea of turning the upper part down flat so that the needles were in a vertical position instead of being horizontal, and the work was carried off horizontally instead of vertically. His first machine produced four identical pieces simultaneously, but this number was soon increased. Cotton was induced by the success of his invention to begin machine building as a separate business and thus established one of the first of a class of engineering firms that sprung up as an adjunct to the new hosiery manufacture. He employed only a dozen men and turned out six machines in the first year, entering into an agreement with Hine \& Mundella for their exclusive use. This was later extended to the firm of I. \& R.Morley. In 1878, Cotton began to build on his own account, and the business steadily increased until it employed some 200 workers and had an output of 100 machines a year.[br]Bibliography1863, British patent no. 1,901 (flat-frame knitting machine).Further ReadingF.A.Wells, 1935, The British Hosiery and Knitwear Industry: Its History and Organisation, London (based on an article in the Knitters' Circular (Feb. 1898).A brief account of the background to Cotton's invention can be found in T.K.Derry and T.I.

14 Nash, John
SUBJECT AREA: Architecture and building[br]b. c. 1752 (?) London, Englandd. 13 May 1835 Cowes, Isle of Wight[br]English architect and town planner.[br]Nash's name is synonymous with the great scheme carried out for his patron, the Prince Regent, in the early nineteenth century: the development of Marylebone Park from 1811 constituted a "garden city" for the wealthy in the centre of London. Although only a part of Nash's great scheme was actually achieved, an immense amount was carried out, comprising the Regent's Park and its surrounding terraces, the Regent's Street, including All Souls' Church, and the Regent's Palace in the Mall. Not least was Nash's exotic Royal Pavilion at Brighton.From the early years of the nineteenth century, Nash and a number of other architects took advantage of the use of structural materials developed as a result of the Industrial Revolution; these included wrought and cast iron and various cements. Nash utilized iron widely in the Regent Street Quadrant, Carlton House Terrace and at the Brighton Pavilion. In the first two of these his iron columns were masonry clad, but at Brighton he unashamedly constructed iron column supports, as in the Royal Kitchen, and his ground floor to first floor cast-iron staircase, in which he took advantage of the malleability of the material to create a "Chinese" bamboo design, was particularly notable. The great eighteenth-century terrace architecture of Bath and much of the later work in London was constructed in stone, but as nineteenth-century needs demanded that more buildings needed to be erected at lower cost and greater speed, brick was used more widely for construction; this was rendered with a cement that could be painted to imitate stone. Nash, in particular, employed this method at Regent's Park and used a stucco made from sand, brickdust, powdered limestone and lead oxide that was suited for exterior work.[br]Further ReadingTerence Davis, 1960, The Architecture of John Nash, Studio.——1966, John Nash: The Prince Regent's Architect, Country Life.Sir John Summerson, 1980, John Nash: Architect to King George IV, Allen \& Unwin.DY -
15 Leschot, Georges Auguste
[br]b. 24 March 1800 Geneva, Switzerlandd. 4 February 1884 Geneva, Switzerland[br]Swiss clockmaker, inventor of diamond drilling.[br]By about 1843, Leschot, who was renowned for designing machines to produce parts of clocks on an industrialized scale, had gathered that the fine, deep lines he found on an Egyptian red porphyry plate must have been cut by diamonds. He thus resurrected a technology that had been largely forgotten over the centuries, when in 1862 his son, who was engaged in constructing a railway line in Italy, was confronted with the problems of tunnelling through hard rock. In Paris he developed a drilling machine consisting of a casing that rotated in a similar way to the American rope drilling method. The crown of the machine was mounted with eight black diamonds, and inside the casing a stream of water circulated continuously to flush out the mud.He took out his first patent in France in 1862, and followed it with further ones in many European countries and in America. He continued to concentrate on his watchmaker's profession and left the rights to his patents to his son. It was Leschot's ingenious idea of utilizing diamonds for drilling hard rock that was later applied in different mining processes. It influenced a series of further developments in many countries, including those of Alfred Brandt and Major Beaumont in England. In particular, the fact that the hollow casing produced a complete core was of importance for the increasing amount of petroleum prospecting in Pennsylvania after Edwin Laurentine Drake's find of 1859, where M.C.Bullock sunk the first deep well (200 m) in the world by diamond drilling in 1870. The efforts of Per Anton Crælius in Sweden made diamond drilling a success worldwide.[br]Further ReadingD.Colladon, 1884, "Notice sur les inventions mécaniques de M.G.Leschot, horloger", Archives des Sciences Physiques et Naturelles 3, XI (1):297–313 (discusses the influences of Leschot's invention on other engineers in Europe).D.Hoffmann, 1962, "Die Erfindung der Diamantbohrmaschine vor 100 Jahren", Der Anschnitt 14(1):15–19 (contains detailed biographical outlines).WKBiographical history of technology > Leschot, Georges Auguste

16 Mond, Ludwig
SUBJECT AREA: Chemical technology[br]b. 7 March 1839 Cassel, Germanyd. 11 December 1909 London, England[br]German (naturalized English) industrial chemist.[br]Born into a prosperous Jewish merchant family, Mond studied at the Polytechnic in Cassel and then under the distinguished chemists Hermann Kolbe at Marburg and Bunsen at Heidelberg from 1856. In 1859 he began work as an industrial chemist in various works in Germany and Holland. At this time, Mond was pursuing his method for recovering sulphur from the alkali wastes in the Leblanc soda-making process. Mond came to England in 1862 and five years later settled permanently, in partnership with John Hutchinson \& Co. at Widnes, to perfect his process, although complete success eluded him. He became a naturalized British subject in 1880.In 1872 Mond became acquainted with Ernest Solvay, the Belgian chemist who developed the ammonia-soda process which finally supplanted the Leblanc process. Mond negotiated the English patent rights and set up the first ammoniasoda plant in England at Winnington in Cheshire, in partnership with John Brunner. After overcoming many difficulties by incessant hard work, the process became a financial success and in 1881 Brunner, Mond \& Co. was formed, for a time the largest alkali works in the world. In 1926 the company merged with others to form Imperial Chemical Industries Ltd (ICI). The firm was one of the first to adopt the eight-hour day and to provide model dwellings and playing fields for its employees.From 1879 Mond took up the production of ammonia and this led to the Mond producer-gas plant, patented in 1883. The process consisted of passing air and steam over coal and coke at a carefully regulated temperature. Ammonia was generated and, at the same time, so was a cheap and useful producer gas. Mond's major discovery followed the observation in 1889 that carbon monoxide could combine with nickel in its ore at around 60°C to form a gaseous compound, nickel carbonyl. This, on heating to a higher temperature, would then decompose to give pure nickel. Mond followed up this unusual way of producing and purifying a metal and by 1892 had succeeded in setting up a pilot plant to perfect a large-scale process and went on to form the Mond Nickel Company.Apart from being a successful industrialist, Mond was prominent in scientific circles and played a leading role in the setting up of the Society of Chemical Industry in 1881. The success of his operations earned him great wealth, much of which he donated for learned and charitable purposes. He formed a notable collection of pictures which he bequeathed to the National Gallery.[br]Principal Honours and DistinctionsFRS 1891.Bibliography1885, "On the origin of the ammonia-soda process", Journal of the Society of Chemical Industry 4:527–9.1895.

17 Goulding, John
SUBJECT AREA: Textiles[br]b. 1791 Massachusetts, USA d. 1877[br]American inventor of an early form of condenser carding machine.[br]The condenser method of spinning was developed chiefly by manufacturers and machine makers in eastern Massachusetts between 1824 and 1826. John Goulding, a machinist from Dedham in Massachusetts, combined the ring doffer, patented by Ezekiel Hale in 1825, and the revolving twist tube, patented by George Danforth in 1824; with the addition of twisting keys in the tubes, the carded woollen sliver could be divided and then completely and continuously twisted. He divided the carded web longitudinally with the ring doffer and twisted these strips to consolidate them into slubbings. The dividing was carried out by covering the periphery of the doffer cylinder with separate rings of card clothing and spacing these rings apart by rings of leather, so that instead of width-way detached strips leaving the card, the strips were continuous and did not require piecing. The strips were passed through rotating tubes and wound on bobbins, and although the twist was false it sufficed to compress the fibres together ready for spinning. Goulding patented his invention in both Britain and the USA in 1826, but while his condensers were very successful and within twenty years had been adopted by a high proportion of woollen mills in America, they were not adopted in Britain until much later. Goulding also worked on other improvements to woollen machinery: he developed friction drums, on which the spools of roving from the condenser cards were placed to help transform the woollen jenny into the woollen mule or jack.[br]Bibliography1826, British patent no. 5,355 (condenser carding machine).Further ReadingD.J.Jeremy, 1981, Transatlantic Industrial Revolution.

18 decision making
Gen Mgtthe process of choosing between alternative courses of action. Decision making may take place at an individual or organizational level. The process may involve establishing objectives, gathering relevant information, identifying alternatives, setting criteria for the decision, and selecting the best option. The nature of the decision-making process within an organization is influenced by its culture and structure, and a number of theoretical models have been developed. One well-known method for individual decision making was developed by Charles Kepner and Benjamin Tregoe in their book The New Rational Manager (1981). Decision theory can be used to assist in the process of decision making. Specific techniques used in decision making include heuristics and decision trees. Computer systems designed to assist managerial decision making are known as decision support systems. -
19 work measurement
Gen Mgtthe establishment of standard times for the completion of particular work tasks to a particular level of performance. In work measurement, tasks are broken down into elements. The time required for each is established and an assessment of relaxation and contingency allowances is made. Work measurement forms part of work study and is normally conducted subsequent to method study with the aim of increasing efficiency and productivity. Work measurement was developed in the context of industrial production management but has recently become more widely used. Time study and predetermined motion-time systems are used in work measurement. -
