Quantum analogs of classical codes
(English) The main focus of this thesis are stabilizer codes, a type of error-correcting code used to correct quantum information that has been corrupted by noise. We introduce several new general constructions of stabilizer ...
A proposal for a new method to assess road traffic noise in the United Kingdom
(English) This thesis proposes a novel approach for assessing road traffic noise in the United Kingdom, aiming to partially revise the existing methodology outlined in the Design Manual for Roads and Bridges (DMRB). This ...
Advances towards a robust AI-based glioma grading system
(English) Gliomas represent the most common and aggressive form of primary brain tumors in adults, posing significant diagnostic challenges due to their heterogeneous molecular, histological, and radiological characteristics. ...
Precision agriculture in fruit orchards: development and evaluation of a smart sprayer for variable rate pesticide application in 3D crops
(English) European agriculture is currently experiencing an intense debate about the production model, linked to a growing social awareness regarding the use of agrochemicals in general, and plant protection products in ...
Photonic-assisted wireless millimeter-wave and terahertz imaging and communications
(English) This thesis investigates the design, development, and characterization of optical-enabled wireless systems operating in the millimeter wave (mmWave) and Terahertz (THz) frequency ranges, addressing the need for ...
El disco de Aragó: análisis electrodinámico de rotores discoidales conductores
(English) In this thesis, important ideas like electricity, magnetism, electric motors, special relativity, and history are explained. This is because, on the one hand, the historical memory of Francesc Aragó, a 19th-century ...
Desarrollo de un sistema de apoyo a la toma de decisión para la evaluación cuantitativa de los equipos de aplicación de productos fitosanitarios en función del riesgo medioambiental
(English) Since the adoption of the Machinery Directive 2009/127/EC and the implementation of the new Machinery Regulation (EU) 2023/1230, which will be mandatory from 2027, manufacturers of agricultural sprayers have ...
Neuromuscular function assessment through EMG in using hybrid learning in real-time
(English) Understanding and accurately analyzing electromyography (EMG) signals is paramount for a multitude of applications ranging from muscular function assessment to neural decoding and interfacing. The general objective ...
Evaluación de la resistencia residual. Efecto de la velocidad de corte, temperatura e interacción termo-hidro-mecánica (THM)
(English) The study of residual soil strength and its dependence on intrinsic, external, and coupled effects has gained significant scientific interest due to its relevance in geotechnical field. This doctoral thesis ...
An unconditionally stable mimetic finite volume method on collocated grids
(English) An unconditionally stable mimetic Finite Volume Method for unstructured collocated grids is presented in this thesis. The theoretical requirements for the mimetic framework rely on differential geometry and ...
Clinical comparison of two specialty soft lenses for Keratoconus
(English) Due to advanced diagnostic instruments for detection of early-stage keratoconus (KC), and procedures that halt its progression such as corneal collagen cross-linking (CXL), optometry clinics are now seeing less ...
Towards shock absorbing hyperelastic metamaterial design
(English) This thesis explores the possibilities and benefits of computational tools to be used in the analysis and design of shock absorbing metamaterials for industrial applications. The research is organized into two ...
Integración de la relación salud humana y cambio climático en el marco de la resiliencia urbana: propuesta metodológica de evaluación y operacionalización en un contexto latinoamericano
(English) This study addresses the relationship between climate change and human health in the framework of urban resilience in a Latin American context. It sought to strengthen the climate and health components through ...
Access mechanisms for massive Internet of Things in 5G and beyond networks
(English) The Massive Internet of Things (MIoT) characterizes a communication scenario where a massive number of battery-operated devices perform infrequent, primarily uplink-oriented small data transmissions to a network. ...
Applications of the OCATA optical layer digital twin
(English) Optical transport networks (OTNs) are a core infrastructure and key-enabler of today’s hyper-connected society as most of the Internet data traffic is transferred over optical fibers. Traffic demand is experiencing ...
Control design for converters in modern power system
(English) Dynamic behavior of modern power system is increasingly influenced by the dynamics of power converters. At the generation level, a high volume of wind and solar energy with their large-scale power converters are ...
A face-centred finite volume solver for viscous laminar incompressible flows using OpenFOAM
(English) Incompressible flow simulations are crucial for numerous scientific and engineering applications, from automotive aerodynamics to biomedical device design. Traditional finite volume (FV) methods, such as the ...
Aerodynamic shape optimization under uncertainties using embedded methods and adjoint techniques
(English) This thesis develops a framework to perform shape optimization under uncertainties for a body under the action of aerodynamic forces. The solution of the flow is performed with finite elements using the full ...
Power control and voltage quality enhancement on inverter-based AC microgrids
