Surface reconstruction methods for seafloor modelling
Underwater maps are an important source of information for the scientific community, since mapping the seafloor is the starting point for underwater exploration. The advance of range scanning methodologies (both acoustic ...
Contribution to micro-milling process parameters selection for process planning operations
The development of new products with micro-metric characteristics and complex geometries has been a manufacturing trend in different industrial sectors, particularly for electronic, military, biomedical and aerospace ...
Transition metal-catalysed [2+2+2] cycloaddition reactions. Methodology and mechanism
The transition-metal catalysed [2+2+2] cycloaddition reaction is a highly efficient synthetic tool that allows six-membered polysubstituted carbo- and heterocyclic derivatives to be obtained in an atom economy process. ...
Rice seeds as biofactories of the production of antimicrobial peptides
A series of antimicrobial peptides (AMPs) derived from the BP134 peptide (a member of the CECMEL11 library) exhibited potent bactericidal effect and low cytotoxicity, and were selected for expression in transgenic rice. ...
El "Tractat de les penes particulars d'infern" de Joan Pasqual: estudi i edició crítica
El Tractat de les penes particulars d’infern de Joan Pasqual, mestre en teologia i franciscà de Castelló d’Empúries, forma part d’una obra de divulgació teològica dividida en dos volums: el Llibre de beatitud, dedicat el ...
La proyección macular, un nuevo método para determinar la agudeza visual potencial
The "Macular Projector" MAP, designed by us, is so effective, reliable and predictive as the Guyton-Minkowski PAMÒ and Retinometer Heine Lambda 100 in the assessment of potential visual acuity. The PAM has the advantage, ...
Multi-attribute auctions: application to workflow management systems
Resource and task allocation for workflows poses an allocation problem in which several attributes may be involved (economic cost, delivery time, CO2 emissions...), therefore, it must be treated from a multi-criteria ...
Sonar scan matching for simultaneous localization and mapping in confined underwater environments
This thesis presents the development of a localization and mapping algorithm for an autonomous underwater vehicle (AUV). It is based on probabilistic scan matching of raw sonar scans within a pose-based simultaneous ...
Reproducció i desenvolupament de la mallerenga blava (Cyanistes caeruleus): conseqüències de la invasió de la formiga argentina (Linepithema humile) en la xarxa tròfica del bosc mediterrani
We investigated whether the Argentine ant (Linepithema humile) invasion modifies the trophic web of the sclerophyllous Mediterranean forests to the point that impacts co-occurring bird communities. We studied if the invaded ...
Numerical modeling of anisotropic granular media
Granular materials are multi-particle systems involved in many industrial process and everyday life. The mechanical behavior of granular media such as sand, coffee beans, planetary rings and powders are current challenging ...
Pobresa, privació i rendes mínimes a Catalunya
The current economic crisis has increased severe poverty as well as severe deprivation levels in our society, putting under stress the existing social protection system. In the Spanish system of social protection, the very ...
Coverage path planning for autonomous underwater vehicles
This thesis proposes new methods to find collision-free paths allowing an AUV to cover an area of the ocean floor with its sensors, which is known as coverage path planning. First, we propose a coverage path planning method ...
Development of new tools for local electron distribution analysis
This thesis focuses in the development and application of new tools for the analysis of the electron distribution in molecules, focusing on the concepts of local spins, and oxidation state. The thesis can be divided into ...
Implementació d'eines avançades de control per a l'eliminació de nitrogen i optimització dels costos energètics a l'EDAR de la Vall del Ges
WWTP present two issues: 1) Get adequate depuration performance; 2) Do it with minimal costs. There are many strategies that can be applied to achieve these requirements, but they cannot be applied indiscriminately. In ...
Development of analytical methodologies for the assessment of odorous and fragrance compounds in wastewater treatment plants
Different analytical methodologies have been developed for the determination of odorous compounds and synthetic fragrances in water and air WWTP samples from Girona and Tarragona provinces. With regards to the odorous ...
Automated underwater object classification using optical imagery
This thesis addresses the problem of automated underwater optical image characterization. Remote underwater optical sensing allows the collection and storage of vast amounts of data for which manual classification may take ...
L'estructura de govern de les universitats públiques del Sistema Universitari de Catalunya
La tesi doctoral "L’estructura de govern de les universitats públiques del Sistema Universitari de Catalunya", proposa una configuració del govern intern de les universitats públiques que aglutina els elements requerits ...
Turismo, pobreza y desarrollo sostenible en el Perú. Los casos de Cuzco, Cajamarca y La Libertad
The present research aims to analyze the relationship between tourism and, the social and economic conditions of the population considered socially and culturally poor. The thesis focuses on the ability to develop tourism ...
Beyond trust. Using fuzzy contextual filters for reliability assessment in multi agent systems
Trust modeling is widely recognized as an aspect of essential importance in the construction of agents and multi agent systems (MAS). As a consequence, several trust formalisms have been proposed over the last years. All ...
Unstructured P2P social search query routing algorithms for agentified social networks
The village paradigm presents some benefits compared with the library paradigm; people can adapt the answer content as a function of who is requesting the information, or furthermore, people can perform clarifications of ...
