    On Logics and Semantics for Interpretability 

    Mikec, Luka (Date of defense: 2021-04-30)

    In the central part of this thesis we study for different interpretability logics the following aspects: completeness for modal semantics, decidability and algorithmic complexity. In particular, we will study two basic ...

    On low degree curves in C(2) 

    Sáez Cornellana, Meritxell (Date of defense: 2014-07-16)

    This thesis studies curves in the symmetric square of a curve, C(2). We characterize them, study their immersion in C(2) and deduce properties of the curve C from the existence of curves in C(2) of specific type. In addition, ...

    On modal expansions of t-norm based logics with rational constants 

    Vidal Wandelmer, Amanda (Date of defense: 2015-09-29)

    According to Zadeh, the term “fuzzy logic” has two different meanings: wide and narrow. In a narrow sense it is a logical system which aims a formalization of approximate reasoning, and so it can be considered an extension ...

    On model predictive control for economic and robust operation of generalised flow-based networks 

    Grosso Pérez, Juan Manuel (Date of defense: 2015-03-26)

    This thesis is devoted to design Model Predictive Control (MPC) strategies aiming to enhance the management of constrained generalised flow-based networks, with special attention to the economic optimisation and robust ...

    On multicomponent reactive transports in porous media: from the natural complexity to analitycal solutions 

    Donado Garzón, Leonardo David (Date of defense: 2009-10-05)

    El transporte de solutos no conservativos en medios porosos o fracturados es altamente influenciado por su heterogeneidad. Complejidad adicional se agrega al proceso de transporte, debido a la presencia de diferentes tipos ...

    On nonconvex special relativistic hydrodynamics 

    Berbel Palomeque, Marina (Date of defense: 2023-10-18)

    Aquesta tesi està dedicada a l'estructura d'ones complexes que apareixen en la hidrodinàmica de situacions relativistes quan es consideren fluids realistes amb una termodinàmica sofisticada. L'equació d'estat és una relació ...

    On Normal Forms and Splitting of Separatrices in Reversible Systems 

    Lázaro Ochoa, José Tomás (Date of defense: 2003-10-23)

    És difícil dibuixar una frontera, dins la Teoria de Sistemas Dinàmics, entre lleis de conservació i simetries doncs, sovint, les seves característiques es confonen. Un clar exemple d'aquest fenómen el constitueixen els ...
