Abstract: E-SEASON is the acronym for Europe-South East Asia Science Oriented Network which is an informal network enrolling a number of European and Asian universities and having as kernel of all of its activities: mathematics. We want to present the E-SEASON, the academic cooperation developed inside as well as the ongoing projects. In particular we will pay attention to its research goals. 2023-07-13T23:00:00Z http://hdl.handle.net/10174/40347 Title: 2×2 Nonlinear hyperbolic systems of conservation laws Authors: Correia, Joaquim M.C. Abstract: After we review a few discontinuous solution issues intrinsic to first order hyperbolic systems of conservation laws we consider the case of the 2 × 2 systems and their diffusive-dispersive approximations. 2024-02-02T00:00:00Z http://hdl.handle.net/10174/36763 Title: Modelação de eventos extremos -uma introdução: aplicação ao decatlo e ao heptatlo atlético Authors: Silva, Domingos; Caeiro, Frederico; Oliveira, Manuela Abstract: Seminário sobre Modelação de eventos extremos –uma introdução: aplicação ao decatlo e ao heptatlo atlético, apresentado ao Programa de Doutoramento Em Matemática da UÉvora. 2021-01-27T00:00:00Z http://hdl.handle.net/10174/34041 Title: COVID-19: How to estimate the percentages of asymptomatic and immune individuals Authors: Oliveira, Manuela; Mexia, João T.; Garção, Eugénio; Grilo, Luís M. Abstract: Epidemiology focuses on the identification of patterns in disease occurrence in order to provide information that may be useful to help prevent it. The research of how a disease may be transmitted is influential for that identification. In the case of COVID-19 this research should focus on the relations between the disease and the populations of susceptible individuals that might be infected. In this context, we propose an approach based on a stratified sampling scheme to estimate the percentages of asymptomatic and immune persons per region in Portugal. 2020-09-09T23:00:00Z
