Mixed logical dynamical modelling of renewable hydrogen refuelling stations for the design of optimization-based operational schemes
(2025-09-01)
Article
Open AccessThis paper proposes a Mixed Logical Dynamical (MLD) model for a real-world Hydrogen Refuelling Station (HRS) currently under development, incorporating on-site production, multi-pressure hydrogen storage, and discrete ... -
Kahan–Hirota–Kimura maps preserving original cubic Hamiltonians
(Elsevier, 2025-12)
Article
Open AccessWe study the class of cubic Hamiltonian vector fields whose associated Kahan–Hirota–Kimura (KHK) maps preserve the original Hamiltonian function. Our analysis focuses on these fields in R2 and R4, extending to a family of ... -
On the size of immune sets in the k-PULL infection model
(Elsevier, 2025-11-15)
Article
Open AccessThis paper addresses immune sets in graphs, which are subsets of nodes that remain unaffected during the spread of influence, failure, or infection. The specific propagation model examined is the $k$-PULL infection rule, ... -

Integration of spatial and temporal patterns for ecological environment management in river-riparian system
(Universitat Politècnica de Catalunya, 2025-05-14)
Doctoral thesis
Open Access(English) Rivers are important carriers of water resources and important components of ecosystems. In some areas, rivers have been artificially narrowed, riparian areas have been encroached upon, riparian resources have ... -
Meander resonator coupled UHF RFID system for biomechanics sensing applications
(2025-05-15)
Article
Open AccessThis paper presents a biomechanics sensing system based on an ultra-high frequency (UHF) RFID tag coupled with a meander resonator for motion tracking and displacement sensing. The variations in their relative position ... -
Breathable artificial magnetic conductor with ground-grid structure for shielding wearable antenna sensors
(Elsevier, 2025-09-01)
Article
Open AccessThis paper presents a breathable ground-grid based artificial magnetic conductor (GG-AMC) designed to shield wearable antenna sensors while maintaining user comfort. Unlike traditional AMCs with solid ground planes, the ... -
Optimising food baskets in a local food pantry: the case study of El Rebost
(2025-05)
Article
Open AccessFood banks and food pantries play a crucial role in addressing global food insecurity by collecting and distributing food resources to vulnerable populations. However, effectively addressing diverse nutritional needs and ... -
Novel hydrogen emissions intensity index for solid oxide electrolysis using external thermal energy sources, considering thermodynamic performance of the electrolyser
(Elsevier, 2025-07-07)
Article
Open AccessLow-emission electrolytic hydrogen (LEH), produced electrolytically using renewable energy, is essential for decarbonising the global economy, particularly that of the European Union. However, high-temperature electrolysis ... -
