This thesis is divided into three parts, each one focuses on a different problem related to the study of the Langevin process, described at each time by its position and velocity vectors. We consider here an arbitrary dimension and for the purpose of

Bootstrap percolation and kinetically constrained models in homogeneous and random environments

Autor: Shapira, Assaf

Publikováno v: General Mathematics [math.GM]. Université Sorbonne Paris Cité, 2019. English. ⟨NNT : 2019USPCC066⟩

This thesis concerns with Kinetically Constrained Models and Bootstrap Percolation, two topics in the intersection between probability, combinatorics and statistical mechanics. Kinetically constrained models were introduced by physicists in the 1980'

Cognitive brain-computer interfaces : From feature engineering to neurophenomenological validation

Autor: Mora Sánchez, Aldo

Publikováno v: Neurons and Cognition [q-bio.NC]. Sorbonne Université, 2018. English. ⟨NNT : 2018SORUS217⟩

This thesis aims at describing in detail the design, implementation and validation of cognitive brain-computer interfaces (cBCI). Chapter 1 introduces cBCI design and brain metastability. In Chapter 2, a specific cognitive function (Working Memory) i

Analyse mathématique de méthodes numériques stochastiques en dynamique moléculaire

Autor: Alrachid, Houssam

En physique statistique computationnelle, de bonnes techniques d'échantillonnage sont nécessaires pour obtenir des propriétés macroscopiques à travers des moyennes sur les états microscopiques. La principale difficulté est que ces états micro

In this thesis, we work on metastability for some stochastic dynamical systems. More precisely, we study some differential or partial differential equations perturbed by an additive white noise in the small noise asymptotic. We compute the expectatio
