This dissertation contains a Hebrew edition and annotated Catalan translation of Isaac the Blind's (1165-1235) Commentary on the Book of Creation. The introduction introduces the historical context in which the author ...
Appearance-based mapping and localization using feature stability histograms for mobile robot navigation
This work proposes an appearance-based SLAM method whose main contribution is the Feature Stability Histogram (FSH). The FSH is built using a voting schema, if the feature is re-observed, it will be promoted; otherwise it ...
Implicaciones de la adiponectina de alto peso molecular en el eje tiroideo y el metabolismo óseo
Adiponectin is a protein secreted by adipose tissue which possesses insulin-sensitivity and anti-atherosclerotic properties. In this work, we will study if high molecular weight adiponectin is a key molecule in the association ...
Path planning with homotopic constraints for autonomous underwater vehicles
This thesis addresses the path planning problem for Autonomous Underwater Vehicles (AUVs) using homotopy classes to provide topological information on how paths avoid obstacles. Looking for a path within a homotopy class ...
Computational modeling of charge transfer in nucleobase-aromatic amino acid complexes
The present thesis models nucleobase-amino acid charge transfer reactions, which can serve as base for future computational investigations of charge transfer processes in DNA-protein systems. Guanine and adenine charge ...
Nodes relacionals en el model Second Life. Producció i singularitat
The virtual worlds realms constitute a new space for exploration in which new forms of communication, production and consumption are generated. The presence of these platforms, based on social interaction, is becoming a ...
Computer vision techniques for early detection of skin cancer
This thesis investigates the problem of developing new computer vision techniques for early detection of skin cancer. The first part of this work presents a novel methodology to correct color reproduction in dermatological ...
Evaluación de la remoción de semillas por roedores y hormigas en pinares mediterráneos afectados por incendios forestales
This study was conducted in burned and harvested areas of Catalonia. It was evaluated the effect of the granivorous in predispersive fruit removal of Smilax aspera and Quercus coccifera and postdispersive seed removal. ...
L'adequació dels Plans de Transició al Treball (PTT) a les persones amb discapacitat. Aplicació d'un pla d'avaluació
In this thesis we start from the position where it is important to provide a new mainstreamed training opportunity that allows people with disabilities to opt for a non-specific environment. These normalised settings should ...
Reactivity of well-defined organometallic copper(III) complexes in carbon-heteroatom bond forming reactions
This thesis is focused on the unexplored field of organometallic copper(III) chemistry. Arylcopper(III) complexes have been proposed as key intermediates in Ullmann condensation reactions that consist in the coupling of ...
Definición de los conceptos "tradicional" e "innovación" en alimentos desde la perspectiva del consumidor europeo
Traditional food products (TFP) are an important part of European culture, identity, and heritage. The main objective of present research is to obtain a consumer-driven definition for the concept of ‘‘traditional food ...
Estructura poblacional y demografía genética en poblaciones de trucha común (Salmo trutta) del Pirineo catalán
In the present study an amplification and genotyping system for 9 microsatellite loci has been developed and used to genotype brown trout (Salmo trutta) individuals. This system has allowed, on one hand, to efficiently ...
"Per Déu i per la Ciència". L'Església i la ciència a la Catalunya de la Restauració (1874-1923)
The author explores into the relationship between science and Church during a period of history in Catalonia in which the Church carried out a series of top level scientific measures, such as the school of geology of the ...
Metalls de transició en la formació d'enllaços carboni-carboni: cicloaddicions [2+2+2] catalitzades per Rh(I) i acoblaments creuats catalitzats per Pd(0) i Ni(0)
Carbon-carbon bond formation reactions catalyzed by transition metals represent one of the most versatile and efficient strategies in organic synthesis. The catalytic transformations contribute to the development of ...
Automatic diagnosis of voltage disturbances in power distribution networks
This thesis proposes a framework for identifying the root-cause of a voltage disturbance, as well as, its source location (upstream/downstream) from the monitoring place. The framework works with three-phase voltage and ...
Impact of chlorophenols and heavy metals on soil microbiota: their effects on activity and community composition, and resistant strains with potential for bioremediation
Pollution by toxic compounds is one of the most relevant environmental damages to ecosystems produced by human activity and, therefore, it must be considered in environmental protection and restoration of contaminated ...
