(Universitat Politècnica de Catalunya, 2019-04-24)
Doctoral thesis
Open AccessThe recent technological advances in the satellite domain such as the use of High Throughput Satellites (HTS) with throughput rates that are magnitudes higher than with previous ones, or the use of large non- Geostationary ... -
Programmable DSP-enabled multi-adaptive optical transceivers based on OFDM technology for software defined networks
(Universitat Politècnica de Catalunya, 2019-04-30)
Doctoral thesis
Open AccessThe dynamic behavior of the traffic demand, due to the advent of technologies such as cloud services or Internet of Things (IoT), is increasing. In fact, heterogeneous connections with different characteristics (bandwidth ... -
Direct lookup and hash-based metadata placement : impact on architecture, performance and scalability of local and distributed file systems
(Universitat Politècnica de Catalunya, 2019-04-29)
Doctoral thesis
Open AccessNew challenges to file systems’ metadata performance are imposed by the continuously growing average number of files existing in file systems. The traditional component based lookup approach can become a performance ... -
Development of a finite volume method for elastic materials and fluid-solid coupled applications
(Universitat Politècnica de Catalunya, 2019-04-12)
Doctoral thesis
Open AccessThis thesis presents the development of a parallel finite volume numerical method to analyse thermoelastic and hyperelastic materials and applied problems with mutual interaction between a fluid and a structure. The ... -

(Universitat Politècnica de Catalunya, 2019-04-29)
Doctoral thesis
Open AccessThe increasing parallelism levels in modern computing systems has extolled the need for a holistic vision when designing multiprocessor architectures taking in account the needs of the programming models and applications. ... -
Conceptual modelling for integrated decision-making in process systems
(Universitat Politècnica de Catalunya, 2019-05-27)
Doctoral thesis
Open AccessThis Thesis addresses the systematic construction of Decision Making Models (DMMs) from the conceptualization stage to its application in specific situations, with special emphasis on !he treatment of scenarios where there ... -
Development of new methodologies for the clinical, objective and automated evaluation of visual function based on the analysis of ocular movements : application in visual health
(Universitat Politècnica de Catalunya, 2019-05-24)
Doctoral thesis
Open AccessHealthy visual function not only relies on good visual acuity. Other systems such as accommodation or binocular vision need to be effective. Binocular vision is the ability of the visual system to coordinate and integrate ... -
Laboratory experiments to evaluate the joint effect between heterogeneity and head fluctuation on mixing, effective porosity and tailing
(Universitat Politècnica de Catalunya, 2019-05-30)
Doctoral thesis
Open AccessTracer visualization in the laboratory at high spatial and temporal resolution can help advance the study of mixing processes. However, grain borders, fluctuations in lighting and non-uniform brightness contribute to produce ... -
Biological interactions between fish and jellyfish in the northwester Mediterranean
(Universitat Politècnica de Catalunya, 2019-05-16)
Doctoral thesis
Open AccessJellyfish are important components of marine ecosystems, being a key link between lower and higher trophic levels. Jellyfish blooms occur sporadically and unpredictably in coastal areas and often have important socio-economic ... -
Spatial, temporal and behavioral patterns of marine protists = Patrons espaials, temporals i de comportament dels protistes marins
(Universitat Politècnica de Catalunya, 2017-09-27)
Doctoral thesis
Open AccessThe oceans are microbial-dominated ecosystems, where protists (single-celled eukaryotes) play fundamental roles performing multiple functions as primary producers, consumers, decomposers as well as trophic linkers in aquatic ... -
Support tools for groundwater management in the proximity of a mine site
(Universitat Politècnica de Catalunya, 2017-06-09)
Doctoral thesis
Open AccessThe natural environment in which we live, is subjected, to a greater or lesser extent, to the pressure of human activity, with water being one of the most sensitive elements. For this reason, aware of this situation, from ...
