Arquitectura radical al dominio público. Juan O’Gorman, programa escolar, 1932
(English) This dissertation focuses on architect Juan O'Gorman's 1932 program for the construction of elementary schools in Mexico City. The main subject of this thesis is the group of 26 new schools designed by O'Gorman ...
Learning particle dynamics: from diffusion to interactions
(English) Understanding how a complex system works from its components, such as a virus invading a cell or particles aggregating in a liquid, is a fundamental question in the study of nature that provides great biological ...
Study of neutron-rich β-delayed emitters relevant for understanding the formation of the r-process rare earth-peak around mass A~160
(English) The r-process is responsible for the formation of nearly half of all nuclei heavier than iron. New elements are synthesized via the r-process, involving neutron-rich nuclei characterized by the emission of neutrons ...
Heating and decoherence due to light scattering in atomic media
(English) Cold atom platforms have become central to quantum technologies such as information processing, simulation, and metrology. Their versatility and high degree of control make them especially powerful. A key ...
Nanoindentation mapping of multiphase materials: statistical analysis and machine learning approaches

Thermo-mechanical performance of steel slag asphalt mixtures and their potential for urban heat mitigation
(English) This doctoral thesis focuses on the study of steel slag from electric arc furnaces as a technically and environmentally viable substitute for natural aggregates in asphalt mixtures. While the primary objective ...
Novel strategies to reduce persistent, mobile, and toxic substances in groundwater and wastewater: impact on agriculture and human health
(English) Water scarcity is one of the most pressing global challenges, particularly in arid and semi-arid regions such as the Mediterranean basin. In countries like Spain, where agriculture is a major consumer of water ...
Analysis of helio-geo-ionospheric proxies for short-term earthquake forecasting
(English) Earthquakes are among the most destructive natural disasters, causing significant infrastructure damage and casualties. Between 1998 and 2018, seismic events resulted in approximately 846000 fatalities and caused ...
Cooperative planning and negotiation in human-robot teams
(English) As robots become increasingly integrated into everyday environments, rigid role paradigms and unilateral control models fall short of enabling meaningful collaboration. Preserving human autonomy while allowing ...
Advanced finite element methods for metal forming and manufacturing process simulation: an application to friction stir welding analysis
(English) This work explores the benefits and challenges of advanced Finite Element Methods for metal forming and manufacturing processes. As these processes become increasingly complex, FEM has emerged as a crucial tool. ...
Hydromechanical simulation of argillaceous rocks for radioactive waste disposal applications
(English) Argillaceous claystones are primarily composed of clay particles of sedimentary origin and contain a substantial amount of chemically precipitated cement, often calcium carbonate, which acts as a bonding agent. ...
Decision support system for coastal area management in response to flooding and coastal erosion: a case study of Tumaco-Nariño
(English) Flood and erosion risk management in coastal areas affected by these processes requires integrated and, when conditions allow, coupled approaches that combine physical, socioeconomic, and cultural factors. This ...
Comportamiento hidráulico de aliviaderos de perfil estricto en zonas de gran altitud
(English) This research explores the influence of altitude on the shape of strict profile spillways and their discharge coefficients, pressure field, and cavitation risk. An experimental campaign has been carried out next ...
