An Introduction to Complex Systems in Environment
Description : The environment is a social issue that continues to grow in importance. Its complexity, both cross-disciplinary and multi-scale, has given rise to a large number of scientific and technological locks, that can be solved using a complex systems approaches. Through this courses we will give some e ...

Extremes (An Introduction to Complex Systems in Environment)
Description : The extreme value theory deals with the stochastic behavior of the minimum and the maximum of random variable. It involves a large variety of applications such as natural phenomena: rainfall, floods, atmospheric turbulence, corrosion...etc. The distribution proprieties of extremes and intermediate ...

Multiscale Analysis: Methods of Analysis (An Introduction to Complex Systems in Environment)
Description : We gave in the courses Multifractal the meaning of the universal multifractal (UM) parameters and , in this courses we will introduce some techniques of estimation of UM parameters based on the scale invariance property of geophysical fields. The first method is the Trace Moment (TM) method which ...

MultiScale Analysis :Multifractal (An Introduction to Complex Systems in Environment)
Description : The multifractal analysis is an appropriate framework for addressing and modelling fields with high spatial and temporal variability, particularly with regard to the characteristics of non-uniformity of the phenomena and their extreme behavior. Therefore, the idea of applying this concepts to the ...

MultiScale Simulations (An Introduction to Complex Systems in Environment)
Description : We have seen during the previous lecture the concept of cascade phenomenology and the different models that can be found in the literature. It has been showed the cascade generation is based on the scale invariance propriety and the multiplicative process. The use of simulation is increasingly ...
