Arquitectura comparada
(English) —I— Architecture is a way of ordering the pieces of the world according to their reciprocal affinities, and this involves comparing. Because the word “architecture”, as well as referring to how buildings, cities, ...
Innovative bulk and interfaces management on Q-1D Sb2Se3 based solar cells
(English) This thesis investigated antimony Q-1D (Sb)-based solar cells as a promising alternative for sustainable energy generation, addressing critical challenges related to material properties, interfaces, and device ...
Interannual to decadal variability in the Southern Ocean surface CO2 fluxes in relation with the large-scale atmospheric modes
(English) Abstract The Southern Ocean (<35◦S), which encircles Antarctica, plays a disproportionately large role in the global carbon cycle, accounting for nearly half of the ocean’s uptake of anthropogenic CO₂. This ...
Novel polyamides containing bio-based units: thermal properties, polymorphic transitions, chemical modifications and evaluation of processing conditions
(English) Nylons, a class of linear polyamides, are well-known materials used in a huge number of different applications. Since the first production occurred during the last years of the 1940s, these polymers showed their ...
Framework for optimizing the construction process in Saudi Arabia: the integration of lean construction, building information modeling (BIM), and emerging technologies
(English) The construction industry in Saudi Arabia is experiencing rapid growth driven by the ambitious Vision 2030, but challenges related to inefficiencies, cost overruns, and delays persist. This research presents a ...
The geometry of vision: a comparative study of Persian architecture and miniature painting as a unified system (Ilkhanid and Timurid periods)
(English) This doctoral thesis explores the shared geometric foundations of Persian architecture and miniature painting between 1256 and 1550, spanning the Ilkhanid, Timurid, and early Safavid periods. It argues that both ...
Metal-decorated ceria-based reducible oxide catalysts for CO2 transformation
(English) Noble metal clusters and single atoms have been considered as effective co-catalysts for the enhancement of carbon dioxide hydrogenation due to their singular geometric structures, electronic properties and unique ...
Mathematical and computational modeling of the active mechanics of multicellular systems: from cell-cell adhesion to epithelial reshaping
(English) This thesis develops theoretical and computational frameworks to model two fundamental mechanical functions of multicellular tissues: cell-cell adhesion and epithelial reshaping. These processes are controlled ...
A contribution to group decision aiding by means of multi-perceptual unbalanced linguistic assessments
(English) In decision-aiding environments under uncertainty, assessments are often expressed in linguistic terms whose meanings can vary significantly between individuals. In this thesis, this variation is modeled through ...
Development of conducting materials as electrodes for biomedical sensors
(English) The cost of healthcare is an increasing concern worldwide, driven by the emergence of new diseases as well as the progression of lifestyle-related conditions. For this reason, expenditure on healthcare-related ...
Analysis of cantilever construction of concrete cable-stayed bridges with time-dependent phenomena
(English) This work presents a study on the construction analysis of cable-stayed bridges built by the cantilever method, with a particular focus on the effects of time-dependent phenomena such as creep and shrinkage. In ...
Excitons in motion: linking structure and transport in energy materials
(English) The growing global energy demand, coupled with the need to reduce CO2 emissions, highlights the urgency of developing sustainable energy solutions. Despite its vast potential, solar energy remains underutilized ...
Eines emergents en el tractament de l'ambliopia anisometròpica i/o estràbica en infants: videojocs d'acció i pel·lícules 3D
(English) This doctoral thesis investigates novel therapeutic strategies for the treatment of anisometropic and/or strabismic amblyopia in children. The research focuses on the use of emerging digital interventions, including ...
Allosteric modulation of mutant rhodopsins folding and function as a new therapeutic strategy for the treatment of retinitis pigmentosa
(English) G protein-coupled receptors (GPCRs) are the largest family of membrane proteins in mammals and are essential for sensing external signals and regulating intracellular signaling pathways. Among GPCRs, rhodopsin ...
Designing deep learning accelerators in the limits of energy efficiency
(English) Deep Neural Network (DNN) models form the backbone of today’s Artificial Intelligence (AI) systems. Their large size and high computational cost have resulted in specialized hardware accelerators being essential ...
Synergy between ground-based remote-sensing instruments for retrieving microphysical-optical-radiative properties of atmospheric aerosols
(English) The improvements in retrieving microphysical, optical, and radiative properties of aerosols can contribute to more detailed local observations and research, support local or global climate modeling and air quality ...
Generación de modelos de procesos y decisiones a partir de documentos de texto
(English) This thesis addresses the importance of formal models for the efficient management of business processes (BPM) and business decision management (BDM) in a constantly evolving corporate environment. Within the BPM ...
Estrategias para una extracción sostenible en minería de superficie
(English) Mining is a fundamental sector for global economic development; however, it faces significant challenges related to the environmental impacts of its operations and the growing demand from stakeholders for sustainable ...
Magnetohydrodynamics enhanced radio blackout mitigation system for spacecraft during planetary entries
(English) Spacecraft entering planetary atmospheres are enveloped by a plasma layer with high levels of ionization, caused by the extreme temperatures in the shock layer. The charged particles in the plasma interact with ...
Computational constitutive modeling of WC-Co hardmetals: from small to large specimen scale
(English) In this thesis, the mechanical behavior of tungsten carbide-cobalt (WC-Co) hardmetal, a multiphase composite, is thoroughly investigated through computational modeling techniques. First, the thesis focusses on ...
