Health and economic convergence in the European Union (1990-2010): an econometric approach
The main aim of this thesis is to evaluate the reduction of economic and health disparities in the European Union from 1990-2010. Through different dynamic panel models, we show that in simple economics terms there has ...
Control and modeling techniques in biomedical engineering: the artificial pancreas for patients with type 1 diabetes
This thesis presents different control strategies, for the closed-loop artificial pancreas, which are based on Model Predictive Control (MPC) and Sliding Mode Control (SMC). Multiple MPC with linear models and gain scheduling, ...
El suburbium de Gerunda. Evolució històrica del pla de Girona en època romana
This doctoral thesis aims to go deep on the knowledge of the city of Gerunda in the Roman period using as a main source of information the data about its suburbium, especially thanks to several archaeological projects ...
Case-based diagnosis of batch processes based on latent structures
The aim of this thesis is to present a methodological approach for the automatic monitoring of batch processes based on a combination of statistical models and machine learning methods. The former is used to model the ...
Valoración de materiales compuestos de HDPE reforzados con fibras de Agave sisalana. Aproximación a un paradigma de geometría fractal para las fibras
Natural fibers have been used recently as reinforcement of polymer-matrix based composites. The present thesis examines the mechanical properties of high density polyethylene (HDPE) composite reinforced with sisal fiber, ...
Caracterização mecânica e biológica de scaffolds produzidos por BioCell Printing
This research work proposes a novel automated and integrated system for the production and in vitro culture of scaffolds, called BioCell Printing. The main goal of the present research work, besides the development of the ...
Caracterització de determinants estructurals de propietats especials de la ribonucleasa pancreàtica humana
Ribonucleases are promising candidates for use in anticancer therapy. There are different ways to endow an RNase with antitumor properties. Targeting the enzyme to the cell nucleus is a potential approach. PE5 is a variant ...
Pollution assessment of arsenic in groundwater: geochemistry and analytical aspects
Apart from the geological controls that can cause As mobilization in groundwater in the Bengal Delta Plain, local anthropogenic factors may also contribute to some extent. Investigations showed that As(III) get enriched ...
Arsenic and its speciation analysis in biological and environmental samples using ICP techniques
Arsenic (As) is one of the common cancers causing contaminant in groundwater of West Bengal, India along with other regions of the world. Scientists believe that As contamination in groundwater of these region are because ...
Design and implementation of a closed-loop blood glucose control system in patients with type 1 diabetes

On the use of energy decomposition analyses to unravel the origin of the relative stabilities of isomers
Structural isomers are molecules that have the same number and type of atoms but arranged in different manner. The isomerization energy is the energy difference between two isomers, i.e. the energy cost corresponding to ...
Nitrate groundwater pollution and aquifer vulnerability: the case of the Osona region
Nitrate groundwater pollution in the Osona region is a persistent and widespread problem. Nitrate concentrations are commonly above the drinking water threshold of 50 mg/L in wells and springs. ANOVA and logistic regression ...
