Enhanced semi-explicit particle finite element method via a modified Strang splitting operator for incompressible flows
This work presents an enhanced version of the semi-explicit particle finite element method for incompressible flow problems. This goal is achieved by improving the methodology that results from applying the Strang splitting ...
Análisis geométrico y gráfico de las pirámides de Le Corbusier (1950-1957)
This paper addresses the issue about the geometrical properties and physical measures of the pyramids that Le Corbusier planned throughout his career; while approaching these bodies through his drawings and perspectives. ...
Gas transport and self-sealing in plastic materials within a multi-scale perspective
This paper investigates, within a multi-scale perspective, the gas transport and self-sealing processes in plastic and low-permeability materials, which is crucial for managing deep geological disposal of radioactive waste. ...
Aproximació tecnològica a la projectació sostenible del patrimoni ordinari
This paper presents a teaching experience carried out within the Architectural Technology course in the second year of the Architecture degree programme, focused on the energy and functional retrofitting of the Spirito ...
Blink rate self-regulation, tear volume and ocular symptoms in expert and naïve action video game players
Clinical relevance: Alterations in blink rate and dynamics are common during visually demanding tasks such as video gaming or digital device use, leading to tear film instability and ocular and visual symptoms. Background: ...
Unveiling the impact of Urban Heat Island (UHI) effect on photovoltaic panel efficiency: A case study in Mashhad, Iran
The deployment of photovoltaic (PV) systems in urban environments is a key strategy for achieving sustainable energy goals and reducing carbon emissions. With rapidly growing urban populations, cities face the compounded ...
Two heads are enough: DualU-Net, a fast and efficient architecture for cell classification and segmentation
Accurate detection and classification of cell nuclei in histopathological images are critical for both clinical diagnostics and large-scale digital pathology workflows. In this work, we introduce DualU-Net, a fully ...
Utilizing optical coherence tomography and machine learning to identify vision abnormalities in pediatric neurofibromatosis type 1 patients
Neurofibromatosis type 1 (NF-1) is a genetic disorder associated with a high risk of vision loss in children. Optical coherence tomography (OCT) provides non-invasive, high-resolution imaging of retinal and optic nerve ...
Echoes through time: EcoPorts: past, present and future
Postprint (published version)
Bubble control in cryogenic fluids by means of an acoustic technique
Cryogenic propellants are used for space exploration missions thanks to their high energy density. However, their storage in orbit is a challenge due to localised evaporation as a result of heat fluxes in the tank. Using ...
Análisis experimental de la influencia del ángulo de torsión de los álabes de turbinas hidrocinéticas Darrieus helicoidales
Las turbinas hidrocinéticas se presentan como una alternativa futura para la obtención de energía de las corrientes de agua de manera sostenible. El aumento de eficiencia de dichas turbinas desde distintas aproximaciones ...
A flexibility management system for providing close-to-real-time power services: an experimental case study in PVZEN microgrid lab
This paper presents a novel flexibility management system to handle short-term power deviations generated by intrinsic variability in generation and demand, and behind-the-meter flexibility provision in a close-to-real-time ...
Universality of entanglement in gluon dynamics
Entanglement of fundamental degrees of freedom in particle physics is generated ab initio in scattering processes. We find that in the case of a pure SU(N) gauge theory, two gluons in a product state can become maximally ...
Evaluation of a vertical axis hydrokinetic turbine for water channels
The growing interest on low-carbon energy systems has been essential to develop new electricity devices based on renewable resources. In this context, channel turbines are an excellent alternative to supply demands that ...
Gold-polymer hybrid metasurface for polarization-independent enhanced third harmonic generation in the ultraviolet
We present a combined experimental and theoretical study of nonlinear light-matter interactions in a three-dimensional gold-polymer hybrid metasurface. In contrast to conventional two-dimensional designs, which by symmetry ...
Inventarios municipales de GEI: una base para la acción climática en Cataluña. Primera parte: Sector Transporte y Residuos
El cambio climático representa uno de los principales desafíos globales, pero afrontarlo requiere acciones efectivas adaptadas a las necesidades y capacidades de cada territorio. Los gobiernos locales son actores clave ...
Diseño de una metodología para cálculo de energía hidrocinética en estuarios: ejemplo de aplicación con el software IBER
En el contexto actual de una creciente demanda energética, la energía hidrocinética provocada por la interacción de mareas y caudales de agua en estuarios de los ríos es una de las fuentes con mayor potencial por explotar. ...
Supersurfaces for grasping, scene generation and contact modeling
In this work we study the use of superquadrics and superquartics for grasping and contact detection. We include an overview of the different formulations that have been derived from the superquadrics, and we group all these ...
Simulation of the burning and dripping cables in fire using the particle finite element method
The behavior of the cable jacket in fire characterized by the tendency to melt and drip constitutes a major source of fire hazard. The reason is that the melted material may convey the flame from one point to another, ...
