Ship propeller induced scour of non-cohesive sediment in low bed-clearance conditions
Ships maneuvering in low bed clearance conditions induce sediment scour due to the high speed jet generated by a rotating propeller. Sediment scour is known to cause instability to quay structures, damage to the bed ...
Flexible architecture for the future internet scalability of SDN control plane
Software-Defined Networking (SDN) separates the control plane from the data plane. The initial SDN approach involves a single centralized controller, which may not scale properly as a network grows in size. Distributed ...
Aportaciones al control corriente de convertidores VSC de sistemas eólicos conectados a redes eléctricas perturbadas
With the increasing development of renewable energy sources and their integration into the grid, international standards require next-generation plants to achieve the same levels of reliability and performance as the current ...
Intertwining the city : the in-between spaces of Caracas as scenarios to achieve urban togetherness
This thesis explores the in-between spaces of the contemporary city, and the role they have in promoting urban togetherness through interstitial practice. By looking at different processes that take place in the borderlands ...
Witnessing non-Markovian evolutions
The formulation of quantum physics stands among the most revolutionary theories of the twentieth century. During the first decades of this century, many phenomena concerning the microscopic world were unexplained or had ...
A framework for the analytical and visual interpretation of complex spatiotemporal dynamics in soccer
Sports analytics is an emerging field focused on the application of advanced data analysis for assessing the performance of professional athletes and teams. In soccer, the integration of data analysis is in its initial ...
Design optimization and performance analysis methodology for PMSMs to improve efficiency in hydraulic applications
In the recent years, water pumping and other hydraulic applications are increasingly demanding motors capable to operate under different working conditions, including variable pressure and volumetric flow demands. Moreover, ...
Cellular and Wi-Fi technologies evolution: from complementarity to competition
This PhD thesis has the characteristic to span over a long time because while working on it, I was working as a research engineer at CTTC with highly demanding development duties. This has delayed the deposit more than I ...
Urban vertical garden: ways to improve living conditions by applying green façades in buildings refurbishment at semi-arid climate
This dissertation aims to improve work conditions in office buildings by implementing vertical greenery systems, such as green façades and living walls in semi-arid climates. Since building energy performance is characterized ...
Smart control of light in edge-emitting lasers
The invention of the laser triggered the study of light-matter interactions. In turn, the advent of artificial structured materials on micro- and nanometer scales has become a fruitful playground to tailor the propagation ...
Diagnosis of low-speed bearings via vibration-based entropy indicators and acoustic emissions
Wind energy is one ofthe main renewable energies to replace fossil fuels in the generation of electricityworldwide. To enhance and accelerate its implementation at a large scale, it is vital to reduce the costs associated ...
Bridging the gap between textual and formal business process representations
In the era of digital transformation, an increasing number of organizations are start ing to think in terms of business processes. Processes are at the very heart of each business, and must be understood and carried out ...
Geologically constrained joint inversion of hydraulic, tracer and ERT data for process visualization
Seawater intrusion (SWI) consists in the movement of seawater (SW) into freshwater (FW) aquifers, contaminating drinking water resources. SWI, along with the parallel reduction of Submarine Groundwater Discharge may lead ...
La Casa de veïns del segle XIX a Barcelona : avaluació tipològica, arquitectònica i estructural-constructiva del tipus de casa de residència del s. XIX, a partir de l'anàlisi dels edificis construïts entre 1800 i 1920, a Ciutat Vella i a l'Eixample Central
La tesi que segueix ha estat dedicada a l’estudi del tipus de casa de residència que es desenvolupa a la Ciutat Romana i Medieval, al Raval i a la primera corona de l’Eixample de Barcelona durant el S.XIX, per l’impuls de ...
Albitization of the granitic basement of the Guilleries and Roc de Frausa Massifs (NE Spain) in relationship to the Permian - Triassic palaeosurface
The granitic basement below the Triassic unconformity in the Guilleries and Roc de Frausa massifs (NE Iberia), presents widespread red stained facies characterized by plagioclase albitization, biotite chlhoritization, ...
Developing innovation competences in engineering education through project-based and challenge-based learning
There is a gap between industry needs and engineering graduates’ competences that since the past two decades has been under discussion. Engineering graduates are perceived as “too theoretical” by the industry and face ...
Exploring twisted bilayer graphene with nano-optics
Nano-optics studies the behaviour of light on the nanoscale. In particular, it probes the interaction of light with objects, often of nanometre-size, and reveals fine details of the material's optical properties. Optoelectronics ...
Narrowband photon pairs for atoms: high resolution spectral engineering and characterisation
This thesis describes experimental work to generate and characterise single photons and photon pairs, with frequency content suitable for controlled interaction with cold rubidium atoms. We describe a photon-pair source, ...
Towards stochastic methods in CFD for engineering applications
Recent developments of high performance computing capabilities allow solving modern science problems employing sophisticated computational techniques. However, it is necessary to ensure the efficiency of state of the art ...
Control strategy of grid connected power converter based on virtual flux approach
Distributed Generation (DG) provides an alternative to the Centralized Generation (CG) by means of generating electricity near to the end user of power with the employment of small-scale technologies to produce electricity, ...
