Este libro conocido por lo asequible de sus explicaciones cubre la teoría de circuitos desde un punto de vista del dominio de tiempo y del fasor y de dominio de frecuencia. Se presentan los elementos pasivos (RLC) y los elementos activos (fuente, amplificadores operacionales) y un dominio de análisis del tiempo de circuitos de AC y DC, y el análisis de fasores y el estado estable de los circuitos de AC para, finalmente, desarrollar los métodos de análisis de las transformadas de Laplace y Fourier y aplicar diversas descripciones de entrada-salida.

Both novice and expert stitchers will find a mine of useful material in this book to help them obtain the best results from their cross stitch work. It is divided into three parts, each section crammed with essential information and valuable hints. Part One covers basic techniques such as reading a chart, the different threads and fabrics available, and how to get stitching with them. Part Two explores creative options including three-dimensional cross stitch, using metallic threads and space-dyed threads, and how best to use the different fabrics available. Part three explores the use of bead, button and charm embellishments, as well as combining other techniques such as Blackwork and Hardanger with cross stitch designs to create textural interest. It introduces designing a sampler by hand or computer, and adapting commercial kits and charts to create unique and personal designs. At the end of the book there is a comprehensive stitch library, an essential reference for those keen to develop their counted thread embroidery skills. This is followed by a design library comprising over 50 pages of original charts, allowing stitchers to explore all the effects described.Finally, finishing techniques are covered such as mounting and framing; illustrated with step-by-step colour photographs, it demonstrates how easily the stitching can be made up into a wide range of stunning projects, from cards and pictures to pincushions and table linen.

Much has been written about the 302 British and Commonwealth soldiers who were executed for military offences during the First World War, but there is usually only a passing reference to those who took part the members of the firing squad, the officer in charge, the medical officer and the padre. What are their stories? Through extensive research, David Johnson explores the controversial story of the men forced to shoot their fellow Tommies, examining how they were selected; how they were treated before, during, and after the executions; and why there were so many procedural variations in the way that the executions were conducted.

This is the tale of two men.The first is Henry Tandey, an ordinary man later deemed to be a hero of the old berserk type, born and brought up in Leamington Spa, Warwickshire, who displayed extraordinary courage to emerge from the First World War as the most decorated British private to survive. The second is Adolf Hitler, who was highly decorated in his service to Germany in the First World War and went on to become one of the most infamous dictators in history, later bringing the world to the brink of destruction during the Second World War. It seems unlikely that their fates should collide. Yet in 1938 Hitler named Tandey as the soldier who spared his life on 28 September 1918 in the aftermath of the Battle of Marcoing an assertion that came as a surprise to Tandey himself. The Man Who Didnt Shoot Hitler tells the story of Tandeys and Hitlers Great War, the moment when their lives became intertwined if in fact they did and how Tandey lived with the stigma of being known not for his chestful of medals for gallantry in service of King and Country, but as the man who let Hitler live.

How does a relatively unknown mining company with zero actual revenue see its stock price violently explode from a few cents to nearly three hundred dollars in a matter of months? This absurd financial phenomenon occurred during the Poseidon Bubble, one of the most spectacular commodity crashes in global economic history.In 1969, amid a global shortage of nickel caused by the Vietnam War, an obscure Australian exploration company named Poseidon NL announced a promising nickel discovery in the remote outback. The mere rumor of a massive deposit triggered an unprecedented frenzy of irrational exuberance on the global stock markets. Desperate investors poured millions into the company without ever seeing geological proof. When it was finally revealed that the ore quality was incredibly poor and extraction was financially unviable, the bubble violently imploded, bankrupting thousands of retail investors overnight.This fascinating macroeconomic autopsy explores the sheer danger of speculative hype. It details the failure of the Australian regulatory agencies, the aggressive media manipulation, and the psychological contagion of mass financial panic.Protect your portfolio from unverified hype. The Poseidon Bubble remains a brutal historical warning about the devastating consequences of trading on rumors rather than fundamental corporate value.
