Enhancing char formation of flame retardant epoxy composites: Onigiri-like ZIF-67 modification with carboxymethyl ß-cyclodextrin crosslinking
(Elsevier, 2024-06-01)
Article
Accés restringit per política de l'editorialTo enhance char formation of flame retardant epoxy (EP) composites, carboxymethyl ß-cyclodextrin (CM-ß-CD) is employed as an etchant for or ZIF-67 derivatives. In the early stage, etching plays a dominant role. The mismatch ... -
Neural network. Game theory coupled approach for predicting flexural performance of fibre-reinforced concrete
(Elsevier, 2024-06-01)
Article
Accés restringit per política de l'editorialThe addition of fibres to concrete is an effective solution for enhancing its post-cracking tensile strength (fctR). Currently, this property is characterized through high-cost and time-consuming experimental tests since ... -
Nonlinear observer for online concentration estimation in vanadium flow batteries based on half-cell voltage measurements
(Elsevier, 2024-06)
Article
Accés obertThis paper presents a nonlinear observer to estimate the active species concentrations in vanadium flow batteries. To conduct the estimation, the observer relies only on current, flow rate and two half-cell voltage ... -
Validation of the Spanish version of the IVI_C VRQoL in children from 8 to 18 years old
(Elsevier, 2024-06)
Article
Accés obertPurpose: To validate the Spanish version of the Impact of Vision Impairment for Children (IVI_C), a vision-related quality of life (VRQoL) questionnaire, using Rasch Analysis. Methods: A translation and adaptation of the ... -
Enhancing performance evaluation of low-cost inclinometers for the long-term monitoring of buildings
(Elsevier, 2024-06)
Article
Accés restringit per política de l'editorialThe development of low-cost structural and environmental sensors has revolutionized monitoring practices across numerous fields, enabling cost-effective solutions for infrastructure and building health assessment. However, ... -
Flow regime analysis of high-pressure transcritical fluids in microducts
(2024-06)
Article
Accés obertMicroduct flows are known for their inherent laminar regimes resulting from the characteristic small dimensions and low velocities. In this regard, direct numerical simulations are employed to investigate an innovative ... -
A novel dual-parameter proximity and touch sensor using SiO2 nanoparticles and NaCl with commercial acrylic-based encapsulation
(Elsevier, 2024-06)
Article
Accés obertThis study shows the development and analysis of a novel capacity proximity sensor (CPS) based on a sensing layer made up of a mixture of silicon dioxide nanoparticles (SiO2) and sodium chloride (NaCl), and an encapsulation ... -
New characterizations and a concept of potential for each multinomial (probabilistic) value
(Elsevier, 2024-05-15)
Article
Accés obertIn this paper we focus on multinomial probabilistic values and we consider two special classes of players: necessary and nullifying players. By introducing new properties related to this kind of players, we provide new ... -
MEMS miniaturized low-noise magnetic field sensor for the observation of sub-millihertz magnetic fluctuations in space exploration
(Elsevier, 2024-05-15)
Article
Accés obertThe objective of this paper is to show that, using magnetic field modulation with a MEMS resonator, it is possible to reduce the noise floor of a commercial Tunneling Magnetic Resistance by one order of magnitude, in the ... -
