Download or read book Electromagnetics and Antenna Optimization using Taguchi s Method written by Wei-Chung Weng and published by Springer Nature. This book was released on 2022-06-01 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new global optimization technique using Taguchi’s method and its applications in electromagnetics and antenna engineering. Compared with traditional optimization techniques, Taguchi’s optimization method is easy to implement and very efficient in reaching optimum solutions. Taguchi’s optimization method is developed based on the orthogonal array (OA) concept, which offers a systematic and efficient way to select design parameters. The book illustrates the basic implementation procedure of Taguchi’s optimization method and discusses various advanced techniques for performance improvement. In addition, the integration of Taguchi’s optimization method with commercial electromagnetics software is introduced in the book. The proposed optimization method is used in various linear antenna arrays, microstrip filters, and ultra-wideband antenna designs. Successful examples include linear antenna array with a null controlled pattern, linear antenna array with a sector beam, linear antenna array with reduced side lobe levels, microstrip band stop filter, microstrip band pass filter, coplanar waveguide band stop filter, coplanar ultra-wide band antenna, and ultra-wide band antenna with band notch feature. Satisfactory results obtained from the design process demonstrate the validity and efficiency of the proposed Taguchi’s optimization method.

Download or read book Oxford Dictionary of National Biography 2005 2008 written by Lawrence Goldman and published by Oxford University Press, USA. This book was released on 2013-03-07 with total page 1253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Who made modern Britain? This book, drawn from the award-winning Oxford Dictionary of National Biography, tells the story of our recent past through the lives of those who shaped national life. Following on from the Oxford DNB's first supplement volume-noteworthy people who died between 2001 and 2004-this new volume offers biographies of more than 850 men and women who left their mark on twentieth and twenty-first century Britain, and who died in the years 2005 to 2008. Here are the people responsible for major developments in national life: from politics, the arts, business, technology, and law to military service, sport, education, science, and medicine. Many are closely connected to specific periods in Britain's recent history. From the 1950s, the young Harold Pinter or the Yorkshire cricketer, Fred Trueman, for example. From the Sixties, the footballer George Best, photographer Patrick Lichfield, and the Pink Floyd musician, Syd Barrett. It's hard to look back to the 1970s without thinking of Edward Heath and James Callaghan, who led the country for seven years in that turbulent decade; or similarly Freddie Laker, pioneer of budget air travel, and the comedians Ronnie Barker and Dave Allen who entertained with their sketch shows and sit coms. A decade later you probably browsed in Anita Roddick's Body Shop, or danced to the music of Factory Records, established by the Manchester entrepreneur, Tony Wilson. In the 1990s you may have hoped that 'Things can only get better' with a New Labour government which included Robin Cook and Mo Mowlam. Many in this volume are remembered for lives dedicated to a profession or cause: Bill Deedes or Conor Cruise O'Brien in journalism; Ned Sherrin in broadcasting or, indeed, Ted Heath whose political career spanned more than 50 years. Others were responsible for discoveries or innovations of lasting legacy and benefit-among them the epidemiologist Richard Doll, who made the link between smoking and lung cancer, Cicely Saunders, creator of the hospice movement, and Chad Varah, founder of the Samaritans. With John Profumo-who gave his name to a scandal-policeman Malcolm Fewtrell-who investigated the Great Train Robbery-or the Russian dissident Aleksandr Litvinenko-who was killed in London in 2006-we have individuals best known for specific moments in our recent past. Others are synonymous with popular objects and experiences evocative of recent decades: Mastermind with Magnus Magnusson, the PG-Tips chimpanzees trained by Molly Badham, John DeLorean's 'gull-wing' car, or the new British Library designed by Colin St John Wilson-though, as rounded and balanced accounts, Oxford DNB biographies also set these events in the wider context of a person's life story. Authoritative and accessible, the biographies in this volume are written by specialist authors, many of them leading figures in their field. Here you will find Michael Billington on Harold Pinter, Michael Crick on George Best, Richard Davenport-Hines on Anita Roddick, Brenda Hale on Rose Heilbron, Roy Hattersley on James Callaghan, Simon Heffer on John Profumo, Douglas Hurd on Edward Heath, Alex Jennings on Paul Scofield, Hermione Lee on Pat Kavanagh, Geoffrey Wheatcroft on Conor Cruise O'Brien, and Peregrine Worsthorne on Bill Deedes. Many in this volume are, naturally, household names. But a good number are also remembered for lives away from the headlines. What in the 1980s became 'Thatcherism' owed much to behind the scenes advice from Ralph Harris and Alfred Sherman; children who learned to read with Ladybird Books must thank their creator, Douglas Keen; while, without its first producer, Verity Lambert, there would have been no Doctor Who. Others are 'ordinary' people capable of remarkable acts. Take, for instance, Arthur Bywater who over two days in 1944 cleared thousands of bombs from a Liverpool munitions factory following an explosion-only to do the same, months later, in an another factory. Awarded the George Cross and the George Medal, Bywater remains the only non-combatant to have received Britain's two highest awards for civilian bravery.
