Habilitation À Diriger Des Recherches Présentée Par Modélisation Numérique Avancée Pour La Géophysique ———— Advanced Numerical Modeling in Geophysics
In this first chapter, we introduce a spectral-element method to simulate seismic wave propagation throughout the entire Earth described as a one-dimensional (1-D) spherically-symmetric model. The method is based upon a weak formulation of the equations of motion and combines the flexibility of a finite-element method with the accuracy of a global pseudospectral method. The finite-element mesh ...
متن کاملEvolution Prospection
This work concerns the problem of modelling evolving prospective agent systems. Inasmuch a prospective agent [1] looks ahead a number of steps into the future, it is confronted with the problem of having several different possible courses of evolution, and therefore needs to be able to prefer amongst them to decide the best to follow as seen from its present state. First it needs a priori prefe...

متن کاملProspection: experiencing the future.
All animals can predict the hedonic consequences of events they've experienced before. But humans can predict the hedonic consequences of events they've never experienced by simulating those events in their minds. Scientists are beginning to understand how the brain simulates future events, how it uses those simulations to predict an event's hedonic consequences, and why these predictions so of...
متن کاملDepression and prospection.
OBJECTIVES Prospection, the mental representation of possible futures, is usually adaptive. When it goes awry, however, it disrupts emotion and motivation. A negative view of the future is typically seen as one symptom of depression, but we suggest that such negative prospection is the core causal element of depression. Here, we describe the empirical evidence supporting this framework, and we ...
