Sommario/riassunto

Many natural phenomena ranging from climate through to biology are described by complex dynamical systems. Getting information about these phenomena involves filtering noisy data and prediction based on incomplete information (complicated by the sheer number of parameters involved), and often we need to do this in real time, for example for weather forecasting or pollution control. All this is further complicated by the sheer number of parameters involved leading to further problems associated with the 'curse of dimensionality' and the 'curse of small ensemble size'. The authors develop, for the first time in book form, a systematic perspective on all these issues from the standpoint of applied mathematics. The book contains enough background material from filtering, turbulence theory and numerical analysis to make the presentation self-contained and suitable for graduate courses as well as for researchers in a range of disciplines where applied mathematics is required to enlighten observations and models.

Sommario/riassunto

This book examines a series of questions associated with the increasing application and implications of biometrics in contemporary everyday life. In the wake of the events of 9/11, the reliance on increasingly sophisticated and invasive technologies across a burgeoning field of applications has accelerated, giving rise to the term 'biometric state'. This book explores how these 'virtual borders' are



created and the effect they have upon the politics of citizenship and immigration, especially how they contribute to the treatment of citizens as suspects. Finally and most importa
