Environmentally friendly phosphorus flame retardant systems for acrylonitrilebutadiene-styrene (ABS): strategies to enhance mechanical properties and development of novel phosphorus/cork powder hybid solutions
(English) Acrylonitrile-butadiene-styrene (ABS) is one of the most widely used and versatile thermoplastic due to its toughness, chemical resistance and processability. These characteristics make it suitable for various ...
Habitat évolutif
(English) Often, studying the multiple variations that a building undergoes is like taking a trip back in time. Discovering what is behind this transformation is like an open book for those who know how to read it, where ...
Capacidad de respuesta de la cadena de suministro: definición del concepto y marco para mejorar la gestión
(English) Research on supply chain responsiveness (SCR) is a topic of interest to academics and professionals because it facilitates the fulfillment of customer expectations in an adequate time and contributes to achieving ...
Bell nonlocality and causal networks
(English) Understanding the cause and effect relationships behind observed correlations is central to how we reason and interact with the world. Causal relationships help us make sense of the patterns we observe and predict ...
Analysis of ICRF heating schemes for tokamaks using predictive integrated plasma modelling
(English) Heating plasmas to fusion-relevant temperatures stands as a pivotal factor in magnetically confined fusion plasmas. The application of radio frequency (RF) heating through electromagnetic waves in the ion cyclotron ...
Design and analysis of battery chargers for electric vehicles based on multilevel neutral-point-clamped technology
(English) This thesis presents an exploration into the field of advanced battery charger design and control, addressing critical needs across a spectrum of modern applications. It first outlines the increasing importance ...
Classical and quantum simulation of quantum matter beyond symmetry breaking
(English) When matter is cooled to temperatures near absolute zero, its quantum nature begins to emerge. The interactions between its microscopic constituents can then lead to the emergence of fascinating physical properties. ...
Evaluación de la calidad óptica de lentes intraoculares en presencia de aberraciones
(English) An intraocular lens (IOL) is an implant that is used in cataract surgery to replace the clouded natural lens (cataract) and restore the loss of transparency. Currently, there is a wide variety of designs, brands, ...
Development of antibacterial, antiresorptive and osteogenic gallium and silver doped titanium implants
(English) The augment in life expectancy has motivated the increase or degenerative disorders, especially in our bones. The skeleton provides us protection and support; however, with aging, bones can undergo an imbalance ...
Wall-bounded high-pressure transcritical turbulence at low Reynolds regimes
(English) The supercritical miniaturization of wall-bounded turbulence has the potential to overcome the microfluidics energy frontier - small rates of mixing and transfer due to the laminar flow regimes induced, resulting ...
Liquid-Liquid membrane contactors for sustainable ammonia recovery and valorization: experimental insights, novel approaches and applications
(English) This comprehensive research represents a significant stride in the exploration of innovative strategies aimed at enhancing ammonia recovery within diverse wastewater streams. The study is structured into distinct ...
Analysis of Q factor degradation mechanisms in BAW resonators
(English) The emergence of smartphones not only changed the way people uses its phone for, but it also changed the traffic amount that networks need to carry, increasing the demand of higher data rates. The overall result ...
High-performance low-dissipation algorithms for simulation of turbulent compressible flows
(English) Motivated by recent advances in computational technology aiming at exascale capabilities, which implies a need for applications capable of taking advantage of these new supercomputing archit ectures, this work ...
Interoperable dynamics-based structural health monitoring framework for civil engineering structures
(English) The methods used nowadays for maintenance and control of infrastructures require modernisation due to the fact that these are based in processes such as visual inspections, which are carried out sporadically in ...
Cognitive robot control strategies for complex surgical environments
(English) This thesis aims to contribute to the development of robotics autonomy in complex tasks based on the cognitive control paradigm. Cognition is a multidisciplinary approach aimed to provide robotic systems with ...
Bringing self-awareness to the extreme edge: a distributed approach for adaptive energy management in WSNs applied to structural health monitoring
(English) In today's landscape, data are increasingly becoming an invaluable resource to enhance decision-making, enable predictive insights, improving operational efficiency, among numerous other applications. Within the ...
Estudio de matrices de pectina modificada y bis-glicinato ferroso, para su aplicación en la fortificación de alimentos
(English) Colloidal matrices of native and oxidized pectin were developed to improve iron bioa-vailability through the digestive tract. Ferrous bisglycinate (Gly-Fe ), obtained by precipitation of glycine chelation to ...
Unraveling hydrological dynamics: climate and human implications in the Magdalena River streamflow and its interaction with Ciénaga Grande de Santa Marta Wetland
(English) This study offers a comprehensive understanding of the hydrological dynamics of the Magdalena River (MR) basin, located in Colombia. Multiple elements that affect streamflow were analyzed, such as climate-forcing ...
Towards a better water resources management and control using bioelectrochemical systems
(English) Freshwater is an extremely scarce yet essential resource for all life forms on planet Earth. Its quality directly impacts the development of human societies as well as the ecosystems balance and health. However, ...
Contribution to the optimisation of natural disasters monitoring: an on-demand execution strategy approach
(English) Natural disasters suppose a risk to life and assets, and can benefit from better early detection and monitoring systems. Current monitoring systems include in-situ instruments located along the Earth's land, such ...
