Modeling and simulation of some cell dispersion problems by a nonparametric method by Christina Surulescu, Nicolae Surulescu

“…Starting from the classical descriptions of cell motion we propose some ways to enhance the realism of modeling and to account for interesting features like allowing for a random switching between biased and unbiased motion or avoiding a set of obstacles.For this complex behavior of the cell population we propose new models and also provide a way to numerically assess the macroscopic densities of interest upon using a nonparametric estimation technique.Up to our knowledge, this is the only method able to numerically handle the entire complexity of such settings.…”

La mécanique de l’endommagement au secours de la mécanique de la rupture : l’évolution de cette idée en un demi-siècle by Marigo, Jean-Jacques

“…In particular, the emphasis is on the creation and development of damage mechanics with its primary ambition to remedy the shortcomings of Griffith’s fracture theory. We underline the successes of this enterprise and the advances it has allowed by insisting on the key role played by the variational approach, but we also show its limits.…”

Reflexões teóricas acerca da “crise ambiental”: possibilidades de novas orientações para as políticas públicas ambientais by José Irivaldo Alves Oliveira Silva

“…It is a reflec-tive academic contribution that was not worked out with propositional claims, but may have practical consequences, including a reorientation of environmental policies based on the understanding of the society we live in. Therefore, the central objective of this study is precisely to address the phenomenon of globalization and its impact and the way in which we can understand it in its various forms. …”
