Book Description
MATLAB dispose de l'outil Neural Network Toolbox qui fournit des algorithmes, des fonctions et des applications pour créer, entraîner, visualiser et simuler des réseaux de neurones. Vous pouvez effectuer la classification, la régression, le clustering, la réduction de dimensionnalité, la prévision de séries temporelles ainsi que la modélisation et le contrôle de systèmes dynamiques. Les réseaux de neurones dynamiques sont efficaces pour la prédiction de séries temporelles. Vous pouvez utiliser l'application Neural Net Time Series pour résoudre différents types de problèmes de séries chronologiques. Dans le premier type de problème de série chronologique, vous souhaitez prédire les valeurs futures d'une série chronologique y(t) à partir des valeurs passées de cette série chronologique et des valeurs passées d'une deuxième série chronologique x(t). Cette forme de prédiction est appelée réseau autorégressif non linéaire avec entrée exogène (externe), ou NARX. Dans le deuxième type de problème de séries chronologiques, une seule série est impliquée. Les valeurs futures d'une série temporelle y(t) sont prédites uniquement à partir des valeurs passées de cette série. Cette forme de prédiction est appelée autorégressive non linéaire, ou NAR. Le troisième problème de série chronologique est similaire au premier type, dans la mesure où deux séries sont impliquées, une série d'entrée (prédicteurs) x(t) et une série de sortie (réponses) y(t). Ici, vous souhaitez prédire les valeurs de y(t) à partir des valeurs précédentes de x(t), mais sans connaître les valeurs précédentes de y(t). Ce livre développe des méthodes de prévision de séries chronologiques à l'aide de réseaux de neurones dans MATLAB.

Book Description
MATLAB has the tool Deep Leraning Toolbox that provides algorithms, functions, and apps to create, train, visualize, and simulate neural networks. You can perform classification, regression, clustering, dimensionality reduction, timeseries forecasting, and dynamic system modeling and control. Dynamic neural networks are good at timeseries prediction. You can use the Neural Net Time Series app to solve different kinds of time series problems It is generally best to start with the GUI, and then to use the GUI to automatically generate command line scripts. Before using either method, the first step is to define the problem by selecting a data set. Each GUI has access to many sample data sets that you can use to experiment with the toolbox. If you have a specific problem that you want to solve, you can load your own data into the workspace. With MATLAB is possibe to solve three different kinds of time series problems. In the first type of time series problem, you would like to predict future values of a time series y(t) from past values of that time series and past values of a second time series x(t). This form of prediction is called nonlinear autoregressive network with exogenous (external) input, or NARX. In the second type of time series problem, there is only one series involved. The future values of a time series y(t) are predicted only from past values of that series. This form of prediction is called nonlinear autoregressive, or NAR. The third time series problem is similar to the first type, in that two series are involved, an input series (predictors) x(t) and an output series (responses) y(t). Here you want to predict values of y(t) from previous values of x(t), but without knowledge of previous values of y(t). This book develops methods for time series forecasting using neural networks across MATLAB

Book Description
Modelling environmental dynamics is critical to understanding and predicting the evolution of the environment in response to the large number of influences including urbanisation, climate change and deforestation. Simulation and modelling provide support for decision making in environmental management. The first chapter introduces terminology and provides an overview of methodological modelling approaches which may be applied to environmental and complex dynamics. Based on this introduction this book illustrates various models applied to a large variety of themes: deforestation in tropical regions, fire risk, natural reforestation in European mountains, agriculture, biodiversity, urbanism, climate change and land management for decision support, etc. These case studies, provided by a large international spectrum of researchers and presented in a uniform structure, focus particularly on methods and model validation so that this book is not only aimed at researchers and graduates but also at professionals.

Book Description
This book summarizes current knowledge regarding the theory of estimation for semiparametric models with missing data, in an organized and comprehensive manner. It starts with the study of semiparametric methods when there are no missing data. The description of the theory of estimation for semiparametric models is both rigorous and intuitive, relying on geometric ideas to reinforce the intuition and understanding of the theory. These methods are then applied to problems with missing, censored, and coarsened data with the goal of deriving estimators that are as robust and efficient as possible.

Book Description
This volume aims to provide a timely view of the state-of-the-art in systems biology. The editors take the opportunity to define systems biology as they and the contributing authors see it, and this will lay the groundwork for future studies. The volume is well-suited to both students and researchers interested in the methods of systems biology. Although the focus is on plant systems biology, the proposed material could be suitably applied to any organism.

Book Description
A comprehensive resource to sustainability and its application to the environmental, industrial, agricultural and food security sectors Sustainability fills a gap in the literature in order to provide an important guide to the fundamental knowledge and practical applications of sustainability in a wide variety of areas. The authors – noted experts who represent a number of sustainability fields – bring together in one comprehensive volume the broad range of topics including basic concepts, impact assessment, environmental and the socio-economic aspects of sustainability. In addition, the book covers applications of sustainability in environmental, industrial, agricultural and food security, as well as carbon cycle and infrastructural aspects. Sustainability addresses the challenges the global community is facing due to population growth, depletion of non-renewable resources of energy, environmental degradation, poverty, excessive generation of wastes and more. Throughout the book the authors discuss the economics, ecological, social, technological and systems perspectives of sustainability. This important resource: • Explores the fundamentals as well as the key concepts of sustainability; • Covers basic concepts, impact assessment, environmental and socio-economic aspects, applications of sustainability in environmental, industrial, agricultural and food security, carbon cycle and infrastructural aspects; • Argues the essentiality of sustainability in ensuring the propitious future of earth systems; and • Authored by experts from a range of various fields related to sustainability.

Book Description
Although the perioperative care of patients by anesthesiologists draws on diverse clinical skills, the principles of anesthesiology and pain management are rooted in the neurosciences. The Neuroscientific Foundations of Anesthesiology thoroughly examines the anesthetic modulation of the central, peripheral, and autonomic nervous systems and will help redefine anesthesiology as a fundamentally neuroscientific field. The book is organized by sections, with each focusing on a different part of the nervous system. State-of-the-art chapters written by thought-leaders in anesthesiology and neuroscience provide a novel and invaluable resource.
