Diagnòstic ambiental Municipal de Sort
El Treball de fi de grau que es presenta a continuació desenvolupa un diagnòstic mediambiental de Sort, un municipi situat a la comarca del Pallars Sobirà, a la província de Lleida. L'objectiu principal del treball és ...
Intermodalidad como regeneración del Torrent de la Pastera, Vilanova i la Geltrú
El proyecto plantea la rehabilitación y revitalización de la traza histórica del Torrent de la Pastera en Vilanova i la Geltrú como eje estructurante del municipio, a través de un conjunto de intervenciones urbanas que ...
Disseny d'un sistema d'autoconsum basat en energia fotovoltaica amb injecció d’excedents a la xarxa
Aquest TFG consisteix en el disseny i l'anàlisi de viabilitat d'una instal·lació fotovoltaica d'autoconsum de 131,53 kWp per a un poliesportiu municipal de Barberà del Vallès, s'ha validat la producció teòrica mitjançant ...
Linking the pressure dependence of the structure and thermal stability to a- and ß-relaxations in metallic glasses
Glasses derive their functional properties from complex relaxation dynamics that remain enigmatic under extreme conditions. Although the temperature dependence of these relaxation processes is well established, their ...
Minimalist and nanoparticle-free selenium-based photocathodes for record performance solar-driven hydrogen evolution
This work reports the highest photoelectrochemical (PEC) performance for selenium (Se)-based photocathodes, achieved through a simple, sustainable, and nanoparticle-free design. A half-cell solar-to-hydrogen (HC-STH) ...
Análisis de la matriz interconexión en un convertidor multifase con control en modo deslizante
En este artículo se presenta un convertidor buck síncrono multifase controlado por un control en modo deslizante (Sliding Mode Control, SMC). Las funciones de conmutación propuestas se componen de un lazo de tensi´ on, que ...
Enhanced selective recovery of rare earth elements from treated acidic mine water as oxalates: experimental optimization on the crystallization stage
Treatment of acid mine water (AMW) from mining activities is an environmental challenge due to the large volumes generated. At the same time, rare earth elements (REEs), classified as Critical Raw Materials by the European ...
Assessing flood hazards and evacuation safety in metro stations: insights from Paral·lel station (Barcelona)
The increasing frequency of extreme rainfall events due to climate change has heightened flood risks in underground transport systems. Metro stations, particularly concourses and staircases, are highly vulnerable, posing ...
Self-assembled charge-complementary hydrogel with sustained release of antimicrobial peptides for periodontitis treatment
Periodontitis is a pathogenic microbial-infected disease where immune dysregulation promotes chronic inflammation and excessive osteoclast activity, causing progressive tissue destruction. Current therapeutic approaches ...
The effect of silk fibroin additive on the properties of tannic acid-based bioadhesives
Hydrogel adhesives have attracted significant attention for diverse biomedical applications, including tissue engineering, wound dressings, crack propagation prevention, and hemorrhage control. In this study, a tissue ...
Gas migration in low-permeability clay-based barriers
Gas migration in low-permeability materials has become a critical focus in energy and environmental geotechnics, particularly for managing the deep geological disposal of radioactive waste. Such waste can release radionuclides ...
How and why false denial constraints are discovered
Denial Constraints (DCs) are a flexible formalism to express many types of data rules, making them a widely adopted tool for many applications. This flexibility led to the development of numerous algorithms to automatically ...
Comparison of image-based direct numerical simulations of right ventricle against 4D flow
Postprint (published version)
Informe i dictamen sobre les anomalies apreciades a part de l'estructura de l'edifici d'Av. Meridiana, 614 (Barcelona)
Es tracta d'un extens informe-dictamen sobre les anomalies estructurals en un edifici. S'hi van aplicar diverses tècniques d'auscultació i d'anàlisi.
Meteotsunamis in the Western mediterranean: a regional analysis from high-frequency sea level observations
Ciutadella harbor, in Menorca (Balearic Islands), is a well-known hotspot for the occurrence of meteotsunamis, i.e., tsunami-like sea level oscillations generated by atmospheric disturbances. This phenomenon represents a ...
Ongoing study on a scaled steel framed structure in a shaking table: preliminary results on the relation between fundamental period variations and damage
The feasibility of the use of fundamental period variations in buildings as damage indicators is analysed by means of a scaled steel framed structure mounted on a lab shaking table. The structure is a five-floor rectangular ...
Scaling ground motion records by considering the inelastic response of soils
One of the main shortcomings of several seismic databases is the lack of ground motion records exhibiting high-intensity values. Consequently, when characterizing seismic risk, or in the design process of a civil infrastructure, ...
Machine learning investigation of marangoni convection in hybrid nanofluids with Darcy-Forchheimer
This research utilizes machine learning to investigate Marangoni convection in a hybrid nanofluid (MnZnFe2O4 +NiZnFe2 O4/H2 O) within a Darcy-Forchheimer porous framework. We conduct both qualitative and quantitative ...
An evapotranspiration evolution model as a function of meteorological variables: a CFD model approach
The study of meteorological variables and evapotranspiration in open spaces using the three spatial dimensions represents a technical challenge since the high computational resources required only enable the problem to be ...
La intervención del patrimonio moderno caribeño en la formación arquitectónica universitaria. experiencias docentes en Caracas y Barranquilla
La vigencia de lo moderno y su categoría de antiguo. El movimiento moderno ha legado, además de un enorme patrimonio ediicado, una concepción de la forma que todavía es objeto de debate para su aplicación en la práctica ...
