(1929-1987)

   Balladeer, singer, poet, musician, composer, and teacher. Known to the public simply as "Zeca" or "José Afonso," he was a student poet, singer, and musician in the 1950s, and premier interpreter of Coimbra fado, creator of a new school of fado music, and leader of a reform movement in popular music. Using his distinctive musical compositions, appealing baritone singing voice, and iconoclastic lyrics of resistance to tyranny, Afonso Santos employed his poetic and musical gifts as instruments of resistance and opposition to the enduring Estado Novo. Two recorded songs became early shots in this war: Balada de Outono (Autumn's Ballad) and Menino d'Oiro (Golden Boy). With diverse, subversive meanings usually disguised in allegory, his lyrics and style eschewed the traditional Coimbra fado's fare of broad sentiment and unrequited love. Instead, Afonso presented new ballads with contemporary resonance. In the mid-1960s, when so many Portuguese youth were drafted and mobilized for Portugal's colonial wars in Africa, he lived and taught school in Mozambique, where he organized opposition to the regime. Later in that colony, he was arrested by the PIDE.

   After his return to Portugal, Afonso's reputation as a rebel ballad-eer grew; among his most celebrated recorded ballads were Cantigas de Maio (Songs of May, 1971) and Venham Mais Cinco (Five More Came, 1973). His famous revolutionary, rallying song, Grândola, Vila Morena, banned by the Estado Novo before 1974, became the single most famous piece of Portuguese revolutionary music in the second half of the 20th century. Grândola featured Afonso's voice and lyrics and expressed a clearly leftist ideology and resistance to tyranny, to the background sounds of marching feet growing louder. Selected by the coup planners of the Armed Forces Movement as a signal for action, a secret password sign to be played over Lisbon radio at about midnight on 24/25 April 1974, this remarkable song acquired new fame and a place in history as both an actual signal for rebel military operations to begin and an enduring revolutionary rallying cry. After the Revolution of 25 April 1974, Grândola became the most potent symbol of the move to topple the Estado Novo and open the way for profound change, as well as a musical icon, equaled only by the iconographic red carnation. The first stanza of Afonso's lyrics, translated from the Portuguese, is: Grândola, dark-brown town, Homeland of Brotherhood The people have more power within you, oh city....

Blith was the son of a cereal and dairy farmer from the Forest of Arden. He wrote a treatise on farming which was of contemporary value in its description of drainage and water meadows, both subjects of particular relevance in the mid-seventeenth century. The book, The English Improver, contains illustrations of agricultural equipment which have become an almost obligatory inclusion in any book on agricultural history. His understanding of the plough is apparent from the text and illustrations, and his was an important step in the understanding of the scientific principles to be applied to its later design. The introduction to the book is addressed to both Houses of Parliament, and is very much an attempt to highlight and seek solutions to the problems of the agriculture of the day. In it he advocates the passing of legislation to improve agricultural practice, whether this be for the destruction of moles or for the compulsory planting of trees to replace those felled.

Blith himself became a captain in the Roundhead Army during the English Civil War, and even added a dedication to Cromwell in the introduction to his second book, The English Improver Improved, published in 1652. This book contains additional information on both practice and crops, an expansion in knowledge which presumably owes something to Blith's employment as a surveyor of Crown lands between 1649 and 1650. He himself bought and farmed such land in Northamptonshire. His advice on the choice of land for particular crops and the implements of best use for that land expressed ideas in advance of their times, and it was to be almost a century before his writings were taken up and developed.

Chappe began his studies at the Collège de Joyeuse, Rouen, and completed them at La Flèche. He was educated for the church with the intention of becoming an Abbé Commendataire, but this title did not in fact require him to perform any religious duties. He became interested in natural science and amongst other activities he carried out experiments with electrically charged soap bubbles.

When the bénéfice was suppressed in 1781 he returned home and began to devise a system of telegraphic communication. With the help of his three brothers, particularly Abraham, and using an old idea, in 1790 he made a visual telegraph with suspended pendulums to relay coded messages over a distance of half a kilometre. Despite public suspicion and opposition, he presented the idea to the Assemblée Nationale on 22 May 1792. No doubt due to the influence of his brother, Ignace, a member of the Assemblée Nationale, the idea was favourably received, and on 1 April 1793 it was referred to the National Convention as being of military importance. As a result, Chappe was given the title of Telegraphy Engineer and commissioned to construct a semaphore (Gk. bearing a sign) link between Paris and Lille, a distance of some 240 km (150 miles), using twenty-two towers. Each station contained two telescopes for observing the adjacent towers, and each semaphore consisted of a central beam supporting two arms, whose positions gave nearly two hundred possible arrangements. Hence, by using a code book as a form of lookup table, Chappe was able to devise a code of over 8,000 words. The success of the system for communication during subsequent military conflicts resulted in him being commissioned to extend it with further links, a work that was continued by his brothers after his suicide during a period of illness and depression. Providing as it did an effective message speed of several thousand kilometres per hour, the system remained in use until the mid-nineteenth century, by which time the electric telegraph had become well established.

Hackworth trained under his father, who was Foreman Blacksmith at Wylam colliery, and succeeded him upon his death in 1807. Between 1812 and 1816 he helped to build and maintain the Wylam locomotives under William Hedley. He then moved to Walbottle colliery, but during 1824 he took temporary charge of Robert Stephenson \& Co.'s works while George Stephenson was surveying the Liverpool \& Manchester Railway and Robert Stephenson was away in South America. In May 1825 Hackworth was appointed to the Stockton \& Darlington Railway (S \& DR) "to have superintendence of the permanent (i.e. stationary) and locomotive engines". He established the workshops at Shildon, and when the railway opened in September he became in effect the first locomotive superintendent of a railway company. From experience of operating Robert Stephenson \& Co.'s locomotives he was able to make many detail improvements, notably spring safety valves. In 1827 he designed and built the locomotive Royal George, with six wheels coupled and inverted vertical cylinders driving the rear pair. From the pistons, drive was direct by way of piston rods and connecting rods to crankpins on the wheels, the first instance of the use of this layout on a locomotive. Royal George was the most powerful and satisfactory locomotive on the S \& DR to date and was the forerunner of Hackworth's type of heavy-goods locomotive, which was built until the mid-1840s.

For the Rainhill Trials in 1829 Hackworth built and entered the locomotive Sans Pareil, which was subsequently used on the Bol ton \& Leigh Railway and is now in the Science Museum, London. A working replica was built for the 150th anniversary of the Liverpool \& Manchester Railway in 1980. In 1833 a further agreement with the S \& DR enabled Hackworth, while remaining in charge of their locomotives, to set up a locomotive and engineering works on his own account. Its products eventually included locomotives for the London, Brighton \& South Coast and York, Newcastle \& Berwick Railways, as well as some of the earliest locomotives exported to Russia and Canada. Hackworth's son, John Wesley Hackworth, was also an engineer and invented the radial valve gear for steam engines that bears his name.

His early life was spent in the Ukraine and he then studied at Tupolev's aeroplane institute in Moscow. In the mid-1930s, just before his thirtieth birthday, he joined the GIRD (Group Studying Rocket Propulsion) under Frederick Zander, a Latvian engineer, while earning a living designing aircraft in Tupolev's bureau. In 1934 he visited Konstantin Tsiolovsky. Soon after this, under the Soviet Armaments Minister, Mikhail N.Tukhachevsky, who was in favour of rocket weapons, financial support was available for the GIRD and Korolov was appointed General-Engineer (1-star) in the Soviet Army. In June 1937 the Armaments Minister and his whole staff were arrested under Stalin, but Korolov was saved by Tupolev and sent to a sharaska, or prison, near Moscow where he worked for four years on rocket-and jet-propelled aircraft, among other things. In 1946 he went with his superior, Valentin Glushko, to Germany where he watched the British test-firing of possibly three V-2s at Altenwaide, near Cuxhaven, in "Operation Backfire". They were not allowed within the wire enclosure. He remained in Germany to supervise the shipment of V-2 equipment and staff to Russia (it is possible that he underwent a second term of imprisonment from 1948), the Germans having been arrested in October 1946. He kept working in Russia until 1950 or the following year. He supervised the first Russian ballistic missile, R-1, in late 1947. Stalin died in 1953 and Korolov was rehabilitated, but freedom under Nikita Kruschev was almost as restrictive as imprisonment under Stalin. Kruschev would only refer to him as "the Chief Designer", never naming him, and would not let him go abroad or correspond with other rocket experts in the USA or Germany. Anything he published could only be under the name "Sergeyev". He continued to work on his R-7 without the approval that he sought for a satellite project. This was known as semyorka, or "old number seven". In January 1959 he added a booster stage to semyorka. He may have suffered confinement in the infamous Kolyma Gulag around this time. He designed all the Sputnik, Vostok and some of the Voshkod units and worked on the Proton space booster. In 1966 he underwent surgery performed by Dr Boris Petrovsky, then Soviet Minister of Health, for the removal, it is said, of tumours of the colon. In spite of the assistance of Dr Aleksandr Vishaevsky he bled to death on the operating table. The first moon landing (by robot) took place three weeks after his death and the first flight of the new Soyuz spacecraft a little later.

Villard was one of the thirteenth-century architect-engineers who were responsible for the design and construction of the great Gothic cathedrals and other churches of the time. Their responsibilities covered all aspects of the work, including (in the spirit of the Roman architect Vitruvius) the invention and construction of mechanical devices. In their time, these men were highly esteemed and richly rewarded, although few of the inscriptions paying tribute to their achievements have survived. Villard stands out among them because a substantial part of his sketchbook has survived, in the form of thirty-three parchment sheets of drawings and notes, now kept in the Bibliothèque Nationale in Paris. Villard's professional career lasted roughly from 1225 to 1250. As a boy, he went to work on the building of the Cistercian monastery at Vaucelles, not far from Honnecourt, and afterwards he was apprenticed to the masons' lodge at Cambrai Cathedral, where he began copying the drawings and layouts on the tracing-house floor. All his drawings are, therefore, of the plans, elevations and sections of cathedrals. These buildings have long since been destroyed, but his drawings, perhaps among his earliest, bear witness to their architecture. He travelled widely in France and recorded features of the great works at Reims, Laon and Chartres. These include the complex system of passageways built into the fabric of a great cathedral; Villard comments that one of their purposes was "to allow circulation in case of fire".

Villard was invited to Hungary and reached there c. 1235. He may have been responsible for the edifice dedicated to St Elizabeth of Hungary, canonized in 1235, at Kassa (now Košice, Slovakia). Villard probably returned to France c. 1240, at least before the Tartar invasion of Hungary in 1241.

His sketchbook, which dates to c. 1235, stands as a memorial to Villard's skill as a draughtsman, a student of perspective and a mechanical engineer. He took his sketchbook with him on his travels, and used ideas from it in his work abroad. It contains architectural designs, geometrical constructions for use in building, surveying exercises and drawings for various kinds of mechanical devices, for civil or military use. He was transmitting details from the highly developed French Gothic masons to the relatively underdeveloped eastern countries. The notebooks were annotated for the use of pupils and other master masons, and the notes on geometry were obviously intended for pupils. The prize examples are the pages in the book, clearly Villard's own work, related to mechanical devices. Whilst he, like many others of the period and after, played with designs for perpetual-motion machines, he concentrated on useful devices. These included the first Western representation of a perpetualmotion machine, which at least displays a concern to derive a source of energy: this was a water-powered sawmill, with automatic feed of the timber into the mill. This has been described as the first industrial automatic power-machine to involve two motions, for it not only converts the rotary motion of the water-wheel to the reciprocating motion of the saw, but incorporates a means of keeping the log pressed against the saw. His other designs included water-wheels, watermills, the Archimedean screw and other curious devices.

Wankel was first employed at the German Aeronautical Research Establishment, where he worked on rotary valves and valve sealing techniques in the early 1930s and during the Second World War. In 1951 he joined NSU Motorenwerk AG, a motor manufacturer based at Neckarsulm, near Stuttgart, and began work on his rotary engine; the idea for this had first occurred to Wankel as early as 1929. He had completed his first design by 1954, and in 1957 his first prototype was tested. The Wankel engine has a three-pointed rotor, like a prism of an equilateral triangle but with the sides bowed outwards. This rotor is geared to a driveshaft and rotates within a closely fitting and slightly oval-shaped chamber so that, on each revolution, the power stroke is applied to each of the three faces of the rotor as they pass a single spark plug. Two or more rotors may be mounted coaxially, their power strokes being timed sequentially. The engine has only two moving parts, the rotor and the output shaft, making it about a quarter less in weight compared with a conventional piston engine; however, its fuel consumption is high and its exhaust emissions are relatively highly pollutant. The average Wankel engine speed is 5,500 rpm. The first production car to use a Wankel engine was the NSU Ro80, though this was preceded by the experimental NSU Spyder prototype, an open two-seater. The Japanese company Mazda is the only other automobile manufacturer to have fitted a Wankel engine to a production car, although licences were taken by Alfa Romeo, Peugeot- Citroën, Daimler-Benz, Rolls-Royce, Toyota, Volkswagen-Audi (the company that bought NSU in the mid-1970s) and many others; Daimler-Benz even produced a Mercedes C-111 prototype with a three-rotor Wankel engine. The American aircraft manufacturer Curtiss-Wright carried out research for a Wankel aero-engine which never went into production, but the Austrian company Rotax produced a motorcycle version of the Wankel engine which was fitted by the British motorcycle manufacturer Norton to a number of its models.

While Wankel became director of his own research establishment at Lindau, on Lake Constance in southern Germany, Mazda continued to improve the rotary engine and by the time of Wankel's death the Mazda RX-7 coupé had become a successful, if not high-selling, Wankel -engined sports car.

   1) Once Established, Schemata Can Control Later Observations

   Once we have accepted a configuration of schemata, the schemata themselves provide a richness that goes far beyond our observations.... In fact, once we have determined that a particular schema accounts for some event, we may not be able to determine which aspects of our beliefs are based on direct sensory information and which are merely consequences of our interpretation. (Rumelhart, 1980, p. 38)

   2) The Nature of Schemata

   Through most of its history, the notion of the schema has been rejected by mainstream experimental psychologists as being too vague. As a result, the concept of the schema was largely shunned until the mid-1970s. The concept was then revived by an attempt to offer more clearly specified interpretation of the schema in terms of explicitly specified computer implementations or, similarly, formally specified implementations of the concept. Thus, Minsky (1975) postulated the concept of the frame, Schank and Abelson (1977) focused on the concept of the script, and Bobrow and Norman (1975) and Rumelhart (1975) developed an explicit notion of the schema. Although the details differed in each case, the idea was essentially the same.... Minsky and the others argued that some higher-level "suprasentential" or, more simply, conceptual structure is needed to represent the complex relations implicit in our knowledge base. The basic idea is that schemata are data structures for representing the generic concepts stored in memory. There are schemata for generalized concepts underlying objects, situations, events, sequences of events, actions, and sequences of actions. Roughly, schemata are like models of the outside world. To process information with the use of a schema is to determine which model best fits the incoming information. Ultimately, consistent configurations of schemata are discovered which, in concert, offer the best account for the input. This configuration of schemata together constitutes the interpretation of the input. (Rumelhart, Smolensky, McClelland & Hinton, 1986, pp. 17-18)

 

дифференцированные по времени тарифы
Расчёт цен на электроэнергию в зависимости от расчётной стоимости электроэнергии в определенный период времени. Дифференцированные по времени тарифы, обычно делятся на три или четыре временных блока за сутки (пиковый, дневной, ночной провал, мини-провал), а также в зависимости от времени года (летний и зимний). Реальные тарифы отличаются от дифференцированных по времени тарифов тем, что они основаны на фактических, а не на расчётных ценах, которые могут колебаться много раз за день и зависеть от погодных условий, а не меняются согласно заранее установленному графику.

time-of-use rates
The pricing of electricity based on the estimated cost of electricity during a particular time block. Time-of-use rates are usually divided into three or four time blocks per twenty-four hour period (on-peak, mid-peak, off-peak and sometimes super off-peak) and by seasons of the year (summer and winter). Real-time pricing differs from time-of-use rates in that it is based on actual (as opposed to forecasted) prices which may fluctuate many times a day and are weather-sensitive, rather than varying with a fixed schedule.
