Filtering and system identification are powerful techniques for building models of complex systems. This 2007 book discusses the design of reliable numerical methods to retrieve missing information in models derived using these techniques. Emphasis is on the least squares approach as applied to the linear state-space model, and problems of increasing complexity are analyzed and solved within this framework, starting with the Kalman filter and concluding with the estimation of a full model, noise statistics and state estimator directly from the data. Key background topics, including linear matrix algebra and linear system theory, are covered, followed by different estimation and identification methods in the state-space model. With end-of-chapter exercises, MATLAB simulations and numerous illustrations, this book will appeal to graduate students and researchers in electrical, mechanical and aerospace engineering. It is also useful for practitioners. Additional resources for this title, including solutions for instructors, are available online at www.cambridge.org/9780521875127.
This book is intended for researchers active in the field of (blind) system identification and aims to provide new identification ideas/insights for dealing with challenging system identification problems. It presents a comprehensive overview of the state-of-the-art in the area, which would save a lot of time and avoid collecting the scattered information from research papers, reports and unpublished work. Besides, it is a self-contained book by including essential algebraic, system and optimization theories, which can help graduate students enter the amazing blind system identification world with less effort.

This book is all about finite wordlength errors in digital filters, con trollers and estimators, and how to minimize the deleterious effects of these errors on the performance of these devices. This does by no means imply that all about finite wordlength errors in filters, controllers and estimators is to be found in this book. We first ventured into the world of finite wordlength effects in 1987 when Gang Li began his PhD thesis in this area. Our more experienced readers might well say 'This shows', but we believe that the extent of our new contributions largely offsets our relative inexperience about the subject that might surface here and there in the book. Our naive view on the subject of finite wordlength errors in 1987 could probably be summarized as follows: • numerical errors due to finite wordlength encoding and roundoff are something that one has to live with, and there is probably not much that can be done about them except to increase the wordlength by improvements on the hardware; • these errors are as old as finite arithmetic and numerical analysis and they must therefore be well understood by now; • thus, if something can be done to minimize their effects, it must have been analysed and put into practice a long time ago. It is almost fair to say that we were wrong on all counts.
After introducing the concept of the birthing pool in the 1970s, Michel Odent has continuously expanded his interest in the mysterious connections between humans and water. In Planet Ocean he shows that the evolution of the oceans – particularly the fluctuations of sea levels – and the evolution of humans are inseparable. The oceans are the givers and sustainers of life, holding ninety-five per cent of the planet’s habitable space within their immense depths. Odent steers us towards a radically new vision of human nature. Our defining feature – a supersized brain – becomes a leitmotif that enables links between topics as diverse as our nutritional needs, our relationship with sea mammals, and the way members of our species give birth. He relates ‘transcendent emotional states’ with what the French writer Romain Rolland referred to as ‘the oceanic feeling’ – both suggesting the absence of limits. Access to such states can be associated with, for example, a ‘foetus ejection reflex’. This leads to the extraordinary conclusion that swimming – as learnt behaviour among humans – the birth process and access to transcendence are interrelated topics for students of human nature. Planet Ocean is a fascinating interdisciplinary study that demonstrates our manifold connections to water and suggests their relevance to everyday life.
When the Nazis invaded neutral Belgium in May 1940, defeat and occupation were inevitable but Belgian armed forces held out against a vastly superior enemy for 18 days. The elected Government went into exile in London but King Leopold III controversially remained with his people as a prisoner.??As described in this authoritative book, Belgians continued the fight both outside and inside their country. There were eventually two complete Belgian RAF squadrons. The Colonial Army defeated the Italians in East Africa and the Belgian Brigade fought from Normandy to Germany.??The Belgian Resistance organized escape routes, sabotaged their occupiers' activities and spied for the Allies. 17,000 died or were executed and a further 27,000 survived detention. Meanwhile others collaborated and fought for the Nazis and large numbers were tried post-war for war crimes and treason.??About half the Jews in Belgium in 1940 died in the Holocaust and there are many stirring stories of courage, as well as tragic ones.??This is an overdue and honest account of one Nation's very varied experiences during five years of Nazi occupation and oppression.
