Mathematical modelling and advanced control design applied to high-pressure electrolyzers for hydrogen production
This thesis is mainly dedicated to the study of high-pressure alkaline electrolysis. Alkaline electrolysis is a well established technology and is commercially available. However, the operation at high pressure for dispensing ...
Mathematical modelling and molecular analysis of a nitrifying packed bed biofilm reactor
MELiSSA (Micro Ecological Life Support System Alternative) és el sistema desenvolupat per l'Agència Espacial Europea (ESA) i el consorci MELiSSA en el camp del suport de vida durant missions de llarga durada a l'espai. ...
Mathematical modelling of angiogenesis as an integrated multicellular process
L’angiogènesi, la formació de nous vasos sanguinis a partir dels preexistents, és essencial per al desenvolupament normal i juga un paper crucial en patologies com el càncer, la diabetis i l’aterosclerosi. Tot i una extensa ...
Mathematical modelling of bioreactors in the MELiSSA regenerative life support system
El projecte MELiSSA (Micro-Ecological Life Support System Alternative) es va concebre per a desenvolupar un sistema tancat de suport vital regeneratiu basat en la integració de sis compartiments biològics en un circuit ...
Mathematical modelling of diffusion processes at the nanoscale
In this thesis we study diffusion processes of nanoparticle evolution and develop appropriate models with the aim of being able to optimise their functions according to the needs of industry. Two distinct diffusion processes ...
Mathematical modelling of pathogen specialisation
L’aparició de nous virus causants de malalties està estretament lligada a l’especialització de subpoblacions virals cap a nous tipus d’amfitrions. La modelització matemàtica proporciona un marc quantitatiu que pot ajudar ...

Mathematical modelling to study infectious diseases: from understanding to prediction
Each year 10 million people die from communicable diseases. They are infectious diseases caused by agents transmitted between individuals. Nowadays, the two infectious diseases that have the greatest impact are tuberculosis ...
Mathematical models and multiscale simulations of cellular secretion processes
Exocytosis is the cellular process whereby a product such as a hormone or a neurotransmitter is released as a response to stimulation. There are a lot of exocytotic cells in mammals, and each cell type has their specific ...
Mathematical models for energy and landscape integrated analysis in agroecosystems
Els models matemàtics s'utilitzen per explicar fenòmens naturals. Com que els fenòmens naturals són molt complexes, per tal d'aprofundir en el seu comportament i ser capaç de fer prediccions sobre ells, es necessita passar ...
Mathematical models of physiologically structured cell populations
En aquesta tesi es té en compte un model no lineal de creixement de població de cèl·lules que s'estructuren pel seu contingut de ciclina i cinases depenents de ciclina (CDK). Aquest model condueix a un sistema no lineal ...
Mathematical programming based approaches for classes of complex network problems : economical and sociological applications
The thesis deals with the theoretical and practical study of mathematical programming methodologies to the analysis complex networks and their application in economic and social problems. More specifically, it applies ...
Mathematical programming for energetic, economic and environmental optimization of building design
L’objectiu d’aquesta tesis és desenvolupar eines sistemàtiques de suport per la presa de decisions basades en mètodes matemàtics pel disseny òptim d’edificis amb mínim cost i mínim impacte ambiental. Avui en dia la societat ...
Mathematical programming models to design and analyse efficient and robust raiway freight transport networks
(English) Searching to achieve an ambitious reduction in greenhouse gas emissions, the European Union has set as a goal a modal shift in freight transport of 30\% by rail or waterborne for the near future. The increasing ...
Mathematical programming-based models for the distribution networks' decarbonization
(English) Climate change is pushing to decarbonize worldwide economies and forcing fossil fuel-based power systems to evolve into power systems based mainly on renewable energies sources (RES). Thus, increasing the energy ...
Mathematical work on the foundation of Jones-Mueller formalism and its application to nano optics
Jones matrix and nondepolarizing Mueller matrix are the basic elements of the calculus of polarization optics. In this thesis we discus other forms that can be used to represent optical properties of deterministic systems. ...
Matrices biológicas y biomarcadores de exposición fetal a drogas de abuso durante el tercer trimestre de la gestación
Introducción El abuso de sustancias en los países occidentales ha acontecido un problema de salud pública. Estas sustancias también son consumidas por embarazadas, afectando al feto y recién nacido, especialmente vulnerables. ...
