Sommario/riassunto |
|
"The book covers a wide range of topics on wind energy conversion and control from the electrical engineering aspect. It includes wind generators and modeling, power converters and modulation schemes, operating principle of fixed and variable speed wind turbines, advanced generator control schemes, active and reactive power controls of individual wind and is a valuable reference book for academic researchers, practicing engineers, and other professionals. The book can also be used as a textbook for graduate level and final year undergraduate-level courses"-- |

Sommario/riassunto |
|
Audio Drama and Modernism traces the development of political and modernist sound drama during the first 40 years of the 20th Century. It demonstrates how pioneers in the phonograph age made significant, innovative contributions to sound fiction before, during, and after the Great War. In stunning detail, Tim Crook examines prominent British modernist radio writers and auteurs, revealing how they negotiated their agitational contemporaneity against the forces of Institutional containment and dramatic censorship. The book tells the story of key figures such as Russell Hunting, who after being jailed for making ‘sound pornography’ in the USA, travelled to Britain to pioneer sound comedy and montage in the pre-Radio age; Reginald Berkeley who wrote the first full-length anti-war play for the BBC in 1925; and D.G. Bridson, Olive Shapley and Joan Littlewood who all struggled to give a Marxist voice to the working classes on British radio. |
