Advanced energy management/control strategies for smart manufacturing systems
This thesis is devoted to the study of the optimisation-based control techniques for the design of control strategies that contribute to improve the energy efficiency of smart manufacturing systems. Currently, manufacturing ...
Valorization of low concentration sugar side-stream from dissolving pulp production
Among the platform chemicals that can be produced from lignocellulosic biomass, furfural (FUR) constitutes a promising intermediate that can be processed into a variety of advanced end products. In this thesis, the ...
Redistribución del uso del espacio viario como gestor eficiente de movilidad
The efficient and equitable use of urban road space considered as a public good and a scarce resource, leads to giving priority to sustainable transport modes (walking, cycling and public transport). Private vehicle sees ...
Sports broadcasting and multiple object tracking with deep learning methods
Since less than a decade ago, deep learning techniques started to dominate many different fields, revolutionizing the possibilities of artificial intelligence. Seeing their potential, industrial sectors started to invest ...
Special values of the triple product p-adic L-function
Let E be an elliptic curve defined over the field of rational numbers and let f be the corresponding newform of weight 2. Let g,h be two weight one newforms whose nebentype characters are mutually inverse. Let V be the ...
Nonlinear analysis of electro-acoustic frequency-selective devices for communications
Nowadays, mobile devices have become a key technology in our lives, making us become part of a connected world, in which millions of mobile handsets are sold every year. In order to satisfy the user demands, many mobile ...
Mathematical and computational modeling of flexoelectricity at mesoscopic and atomistic scales
This PhD thesis focuses on the development of mathematical and computational models for flexoelectricity, a relatively new electromechanical coupling that is present in any dielectric at the micron and sub-micron scales. ...
Análisis de ciclo de vida de sistemas innovadores de almacenamiento eléctrico en litio-azufre (Li-S) para vehículos
The continuous and expected increase of electrification in the transport sector, the so-called "electromobility" revolution, is one of the main drivers of progress in energy storage for vehicle propulsion. Today's electric ...
Image and video object segmentation in low supervision scenarios
Computer vision plays a key role in Artificial Intelligence because of the rich semantic information contained in pixels and the ubiquity of cameras nowadays. Multimedia content is on a rise since social networks have such ...
Low-power read-out ICs for smart electrochemical sensors
Electrochemical sensors are expanding rapidly over other chemical sensoring technologies because of their potential to generate precise, selective, miniaturized and cost-effective analytical devices. These features satisfy ...
Island-based polygeneration systems : feasibility of bBiomass-driven distributed concepts
The colossal risks and challenges posed by climate change require innovative solutions that must fulfil energy service demands sustainably. The concept of small-scale, biomass-based polygeneration (SBP) is one such ...
Low and high-order hybridised methods for compressible flows
The aerospace community is challenged as of today for being able to manage accurate overnight computational fluid dynamics (CFD) simulations of compressible flow problems. Well-established CFD solvers based on second-order ...
Development of metallic functionalized biomaterials with low elastic modulus for orthopedic applications
Titanium (Ti) and Ti alloys have been used for decades for bone implants and prostheses due to its mechanical reliability and good biocompatibility. However, implant-related infections, lack of osseointegration with the ...
Contribución al modelado e implementación de un control avanzado para un proceso de cloración de una estación de tratamiento de agua potable
The effective disinfection in chlorination tanks of drinking water treatment plants depends on many factors that must be taken into account when designing a suitable control system. The chemical characteristics of the water ...
Granular flow characterisation towards an enhanced bulk feeder selection
In the packaging industry, a wide range of powders and bulk solids are handled in bagging equipment using different bulk feeding techniques. Quality of the packaging is critically affected by feeder performance, which is ...
Outcomes of Work-Life Balance (WLB) across two different nations: Iran and Spain
The nature of work has changed in the last decades; rapidly expanding globalization has led to increased competition in the workplace. Moreover, the growth in female labor force participation has led to the forced shifting ...
La memòria d'un paisatge gravat : les pedreres de marès, empremta territorial del paisatge identitari de Mallorca
This research aims to be the manifesto of one of the most widespread landscapes on the island of Mallorca: the marès quarries, and proposes to understand these spaces as part of its landscape, as an essential part of its ...
Arithmetic applications of the Euler systems of Beilinson-Flach elements and diagonal cycles
The main objective of this dissertation is the exploration of certain arithmetic applications of the Euler systems of Beilinson--Flach elements and diagonal cycles. Euler systems have been proved to be a very powerful tool ...
