Sommario/riassunto |
|
The problems of making inferences about the natural world from noisy observations and imperfect theories occur in almost all scientific disciplines. This 2006 book addresses these problems using examples taken from geophysical fluid dynamics. It focuses on discrete formulations, both static and time-varying, known variously as inverse, state estimation or data assimilation problems. Starting with fundamental algebraic and statistical ideas, the book guides the reader through a range of inference tools including the singular value decomposition, Gauss-Markov and minimum variance estimates, |

Kalman filters and related smoothers, and adjoint (Lagrange multiplier) methods. The final chapters discuss a variety of practical applications to geophysical flow problems. Discrete Inverse and State Estimation Problems is an ideal introduction to the topic for graduate students and researchers in oceanography, meteorology, climate dynamics, and geophysical fluid dynamics. It is also accessible to a wider scientific audience; the only prerequisite is an understanding of linear algebra. |

Sommario/riassunto |

Comment le goût de la culture vient-il aux enfants et comment celui-ci évolue-t-il au cours de cette période qui les fait passer de l’enfance à la grande adolescence ? Comment le fait de regarder la télévision, écouter la radio et de la musique, lire des livres et des magazines, jouer à des jeux vidéo, utiliser l’ordinateur et naviguer sur l’internet s’inscrit-il dans le quotidien des jeunes générations et dans quelle mesure contribue-t-il à leur construction identitaire ? Issue d’une enquête longitudinale de grande ampleur qui a suivi les mêmes enfants (près de 4 000) depuis l’âge de 11 ans (en 2002) jusqu’à 17 ans (en 2008), l’étude décrit la fréquence et la diversité des pratiques, usages et consommations des adolescents et l’influence des instances de transmission (parents, famille, école, institutions culturelles, etc.). Cette observation inédite des comportements culturels contribue à la connaissance de la sociologie des jeunes publics, et des trajectoires des enfants au fil des années, entre prises et déprises pour la culture. How do children acquire an appreciation for culture, and how does this change over the period which takes them from childhood to late adolescence? What part does engaging in such activities as watching television, listening to the radio and to music, reading books and magazines, playing video games, using computers and surfing the internet play in the daily lives of young people, and to what extent does it contribute to the construction of their identity? The result of a large-scale longitudinal survey which followed the same children (a sample group of almost 4000) from the age of 11 (in 2002) up to 17 (in 2008), this study describes the frequency and diversity of adolescent practices, uses and consumption, and the influence of transmission agents (parents, family, school, cultural institutions, etc.). This previously-unpublished study into cultural behaviour contributes to the understanding of the sociology of youth culture and the… |
