Dynamic data assimilation is the assessment, combination and synthesis of observational data, scientific laws and mathematical models to determine the state of a complex physical system, for instance as a preliminary step in making predictions about the system's behaviour. The topic has assumed increasing importance in fields such as numerical weather prediction where conscientious efforts are being made to extend the term of reliable weather forecasts beyond the few days that are presently feasible. This book is designed to be a basic one-stop reference for graduate students and researchers. It is based on graduate courses taught over a decade to mathematicians, scientists, and engineers, and its modular structure accommodates the various audience requirements. Thus Part I is a broad introduction to the history, development and philosophy of data assimilation, illustrated by examples; Part II considers the classical, static approaches, both linear and nonlinear; and Part III describes computational techniques. Parts IV to VII are concerned with how statistical and dynamic ideas can be incorporated into the classical framework. Key themes covered here include estimation theory, stochastic and dynamic models, and sequential filtering. The final part addresses the predictability of dynamical systems.

It quickly became a landmark of postcolonial studies. This timely new book offers insights into the field she helped establish. Both polemical and scholarly, Postcolonial contraventions is challenging in its analysis of black Atlantic studies, colonial discourse analysis and postcolonial theory.She provides important new paradigms for understanding imperial literature, Englishness, and black transnationalism. Her concerns range from the metropolitan centre of Conrad's Heart of Darkness, to fatherhood in Du Bois's The Souls of Black Folk; from the marketing of South African literature to cosmopolitanism in Chinua Achebe; from utopian discourse in Benita Parry to Frederic Jameson's theorisation of empire.Chrisman also critically engages with postcolonial intellectuals Paul Gilroy, David Lloyd, Anne McClintock, Edward Said, Gayatri Spivak and Robert Young, uncovering conservatism from unexpected quarters. The book joins a growing chorus of materialist voices within postcolonial studies, and addresses an urgent need for greater attention to the political, historical and socio-economic elements of cultural production.This book will be of interest to students, researchers and teachers of postcolonial studies, theory and literature; black diaspora and Atlantic studies; imperialism and Victorian literature of empire, and British literature of the nineteenth century.DecolonizationEnglishness.Heart of Darkness.South African literature.black Atlantic studies.black transnationalism.colonial discourse analysis.cosmopolitanism.imperial literature.postcolonial theory.utopian discourse.Decolonization.306.2Chrisman Laura174999MiAaPQMiAaPQMiAaPQBOOK996565572003316Postcolonial contraventions1917620UNISA
