    • A scalable online algorithm for passive seismic tomography in underground mines 
      Delplancke, Claire; Fontbona Torres, Joaquín; Prado, Jorge (Soc Exploration Geophysicists, 2020)
      Understanding and monitoring the seismic responses of rock masses to massive mining are crucial for safety and economic viability of ever larger and deeper underground operations. Seismic monitoring can be used to detect ...
    • An online two-stage adaptive algorithm for strain profile estimation from noisy and abruptly changing BOTDR ... 
      Soto, G.; Fontbona Torres, Joaquín; Cortez, R.; Mujica, L. (Elsevier, 2016)
      Strain measurement using BOTDR (Brillouin Optical Time-Domain Reflectometry) is nowadays a standard tool for structural health monitoring. In this context, weak data quality and noise, usually owed to defective fiber ...
    • Long time behavior of telegraph processes under convex potentials 
      Fontbona Torres, Joaquín; Guerin, Helene; Malrieu, Florent (2016)
      We study the long-time behavior of variants of the telegraph process with position-dependent jump rates, which result in a monotone gradient-like drift towards the origin. We compute their invariant laws and obtain, via ...
    • Quantitative Propagation of Chaos for Generalized Kacparticle Systems 
      Cortez, Roberto; Fontbona Torres, Joaquín (Inst Mathematical Statistics, 2016)
      We study a class of one-dimensional particle systems with true (Bird type) binary interactions, which includes Kac's model of the Boltzmann equation and nonlinear equations for the evolution of wealth distribution arising ...
    • Quantitative uniform propagation of chaos for maxwell molecules 
      Cortez, Roberto; Fontbona Torres, Joaquín (Springer, 2018)
      We prove propagation of chaos at explicit polynomial rates in Wasserstein distance for Kac's N-particle system associated with the spatially homogeneous Boltzmann equation for Maxwell molecules. Our approach is mainly based ...
    • Skeletal stochastic differential equations for superprocesses 
      Fekete, Dorottya; Fontbona Torres, Joaquín; Kyprianou, Andreas (Cambridge Univ., 2020)
      It is well understood that a supercritical superprocess is equal in law to a discrete Markov branching process whose genealogy is dressed in a Poissonian way with immigration which initiates subcritical superprocesses. The ...
