Factores de éxito para la implantación y sostenibilidad del Total Productive Maintenance (TPM)
(English) This doctoral thesis aims to broaden the knowledge around the key factors in the implementation and sustainability of Total Productive Maintenance (TPM) with the study of 3 case studies of companies located in ...
Optimizing edge cloud deployments for video analytics
(English) As our digital world and physical realities blend together, we, as users, are growing to expect real-time interaction wherever and whenever we want. Newer internet services require lower latency than a data center ...
Structure-function relationships in sensory G protein-coupled receptors
(English) Perception of the world by an organism is not possible unless decoding the received information through its sensory systems. In vertebrates, G-protein-coupled receptors (GPCRs) and ion channels are principal ...
Nanoscale manipulation of optical fields
(English) Besides its relevant fundamental interest, the in-depth understanding of light-matter interactions at the nanoscale has a profound impact on modern technological applications in diverse areas including ...
Contributions to the characterization and design optimization of power converters based on switching-cell arrays
(English) The search for standardization in power converter design is motivated by the potential of a significant decrease in design time, a significant decrease in converter cost, and an increase in converter performance ...
Hardware knob coordination in multi-threaded systems
(English) Every new generation of high performance computing (HPC) processors brings higher complexity to boost performance: the increasing number of cores within the processor itself, cores with the ability to run multiple ...
Afino microestructural de chapa de acero calidad DDQ mediante procesos de doblado - enderezado
(English) In this thesis, the ability to refine the grain size of a low carbon steel (deep drawing quality, DDQ) was studied by means of two different techniques of Severe Plastic Deformation (SPD). Firstly, the Repetitive ...
Leak supervision in water distribution networks based on model-based and data-driven approaches
(English) This dissertation intends to provide a methodology for leak supervision in the water distribution network (WDN), focusing on detecting, estimating, and locating leaks in the system. Additionally, sensor placement ...
Modelling and vibration control for a submerged piezoelectric cantilever beam
(English) In this thesis, the dynamic model for the piezoelectric cantilever beam is build by using partial differential equation (PDE). To facilitate the parameter estimation procedure and the controller design, a simplified ...
Modelling and control of high-temperature proton exchange membrane fuel cells for combined heat and power comfort applications
(English) In this thesis, a model predictive control-based energy management system for a specific house powered by a high temperature proton exchange membrane fuel cell is presented. Fuel cells and combined heat and power ...
Poisson structures on moduli spaces and group actions
(English) In this thesis, we study Poisson Structures on Moduli Spaces and Group actions. In particular, we focus on b^m-symplectic structures that can be seen both as symplectic structures with singularities and a particular ...
Comportamiento eléctrico de los compuestos de carbono (CFRP): implicaciones para el modelado y fabricación de palas de aerogenerador con elementos estructurales que incorporan compuestos de CFRP
(English) Carbon fiber reinforced composites (CFRP) have been introduced in a very significant way in all areas of industry and the wind energy sector has been no exception. Due to the size of today's wind turbines and the ...
Obtaining and ennobling of cottonised hemp fibres for textile substrates
(English) The main objective of this work has been to obtain fibres and subsequently yarns and fabrics that are suitable for textile applications, through the cottonisation of an agricultural by-product of hemp (Cannabis ...
Novel quantum interactions between light and dense atomic media
(English) The interface between light and cold atomic ensembles is a fundamental platform to unravel the quantum world and develop quantum technological applications. Its success relies on the simple idea that the efficiency ...
Diseño de un sistema de realidad mixta para la puesta en valor de sitios arqueológicos : caso de estudio: complejo piramidal de Cochasquí Ecuador
(English) This research work shows the design of a Mixed Reality (MR) system and its application in a case study. It aims to contribute to the solution of interpretation problems that frequently affect visitors to archeological ...
Few-shot 3D reconstruction of body parts with deep neural networks
(English) In this thesis, we study the problem of reconstructing objects from a concrete category in 3D when few images are available as input, i.e. less than 10. We apply our findings to digitalizing human body parts such ...
Photonic circuits for wireless applications in the microwave, millimeter wave and terahertz bands
(English) This thesis focuses on the emission, processing and detection of electromagnetic radiation in applications where the use of established technologies may limit the achievable frequency or bandwidth. Leveraging ...
Optimization of the bioplastics production from cyanobacteria
(English) Polyhydroxybutyrate (PHB) is one of the most interesting alternatives to conventional plastics, because it has similar properties to polypropylene, it is more biodegradable than other bioplastics, it has really ...
Multifunctional optical surfaces for optoelectronic devices
(English) Highly transparent optical surfaces with anti-reflection (AR) and self-cleaning properties have the potential to increase performance in a wide range of applications, such as display screens, photovoltaic cells ...
Integration of advanced wastewater treatment and reclamation technologies for organic micropollutants removal and promote water reuse
(English) Climate change and overpopulation are responsible for more frequent droughts, and the imbalance in the water resources management leads to a greater competition in the exploitation of freshwater sources. The ...
