Britain Revisited (Mass Observation social surveys)


Britain Revisited (Mass Observation social surveys) By Tom Harrisson Mass Obs Arc

Britain Revisited was first published in 1961. To a degree, the title is self-explanatory, Tom Harrisson wanted to reassess Worktown (Bolton) and other locations twenty years after the original Mass Observation research had been carried out. Harrisson took into the field with him some of those who had first participated, famous mass observers such as Woodrow Wyatt, Humphrey Spender, the painter Julian Trevelyan, and the writers Bill Naughton, John Summerfield and Celia Fremlin. Their findings were a fascinating mix: on the one hand abrupt change, even to the disappearance of spittoons in pubs (but not of spitting!), on the other hand what Harrisson himself described as ‘the astonishing areas of unchange’, habits and practices left untouched by all the convulsions of the intervening years.

Britain (Mass Observation social surveys) By Mass Observation

Britain, although not the first Mass Observation title, was the one that made its name. Britain was published as Penguin Special and is reported as selling over 100, 000 in ten days. It was published in January 1939, and seventy years on Faber Finds are reissuing it. The aim of Mass Observation was to create ‘an anthropology of ourselves’, to provide a study of everyday lives of ordinary people in Britain. In this book, arranged and written by Tom Harrisson and Charles Madge (two of the founders of Mass Observation) the notorious year of 1938 is anatomized. It was the year of Munich. The first half of the book deals with the unfolding crisis, culminating with Neville Chamberlain waving his scrap of paper, the agreement with Hitler, from No. 10 Downing Street. A Mass Observation observer was there. The Press gave wildly misleading impressions of the turn-out. In fact the crowd was under 5000. As the commentary tartly observes, ‘No second division football club could survive on a Chamberlain gate.’ A bleakly comic moment is recorded, ‘P. M. stretches out his arm for silence. Several in crowd appear to take this as a Fascist salute and stretch forth their arms likewise.’ Other chapters deal with the dance craze ‘The Lambeth Walk’, all-in wrestling, the cow’s-head cult of Westhoughton (the chapter is aptly entitled A Slight Case of Totemism) and the Two Minutes’ Silence on Armistice Day. As the Times said then, ‘ . . . With these anthropological spies among us one wonders how statesmen and journalists will ever again dare to speak and write on behalf of ”the people”. For here are ”the people”.

Electrical Actuators Identification and Observation


Electrical Actuators: Identification and Observation By
2010 | 476 Pages | ISBN: 1848210965 | PDF | 15 MB
This helpful resource covers a large range of information regarding electrical actuators. In particular, robustness, a very problematic issue, is fully explored in a dedicated chapter. The text also deals with he estimate of non-measurable mechanical variables by examining the estimate of load moment, then observation of the positioning of a command without mechanical sensor. Finally, it examines the conditions needed to measure variables and real implementation of numerical algorithms. This is a key working resource for electrical engineers.Content: Chapter 1 Identification of Induction Motor in Sinusoidal Mode (pages 1-48): Edouard Laroche and Jean?Paul LouisChapter 2 Modeling and Parameter Determination of the Saturated Synchronous Machine (pages 49-117): Ernest Matagne and Emmanuel de JaegerChapter 3 Real?Time Estimation of the Induction Machine Parameters (pages 119-174): Luc LoronChapter 4 Linear Estimators and Observers for the Induction Machine (IM) (pages 175-250): Maria Pietrzak?David, Bernard de Fornel and Alain BouscayrolChapter 5 Decomposition of a Determinist Flux Observer for the Induction Machine: Cartesian and Reduced Order Structures (pages 251-283): Alain Bouscayrol, Maria Pietrzak?David and Bernard de FornelChapter 6 Observer Gain Determination Based on Parameter Sensitivity Analysis (pages 285-319): Benoit RobynsChapter 7 Observation of the Load Torque of an Electrical Machine (pages 321-404): Maurice Fadel and Bernard de FornelChapter 8 Observation of the Rotor Position to Control the Synchronous Machine without Mechanical Sensor (pages 405-459): Stephane Caux and Maurice Fadel

Discovering Mars A History of Observation and Exploration of the Red Planet [Audiobook]


English | ASIN: B0B3JT6SLR | 2022 | 23 hours and 19 minutes | MP3 | M4B | 640 MB
Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we’ve learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes. Beginning with the Mariner and Viking missions of the 1960s and 1970s, space-based instruments and monitoring systems have flooded scientists with data on Mars’s meteorology and geology, and have even sought evidence of possible existence of life-forms on or beneath the surface. This knowledge has transformed our perception of the Red Planet and has provided clues for better understanding our own blue world.
