Cardona Rubio, Pol; Valiño Garcia, Luis; Ocampo-Martínez, Carlos; Serra, Maria (2025-09-01)
Article
Open Access

This 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

Mañosa Fernández, Víctor; Pantazi, Chara (Elsevier, 2025-12)
Article
Open Access

We 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

Fàbrega Canudas, José; Marcote Ordax, Francisco Javier; Muñoz López, Francisco Javier (Elsevier, 2025-11-15)
Article
Open Access

This 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, ...

Meander resonator coupled UHF RFID system for biomechanics sensing applications

Hussain, Tauseef; Gil Galí, Ignacio; Fernández García, Raúl (2025-05-15)
Article
Open Access

This 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

Hussain, Tauseef; Fernández García, Raúl; Gil Galí, Ignacio (Elsevier, 2025-09-01)
Article
Open Access

This 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

Food 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

El Mariachet Carreño, Jorge; Husar, Attila Peter; Roda Serrat, Vicente; Prieto Araujo, Eduardo; Montesinos Miracle, Daniel (Elsevier, 2025-07-07)
Article
Open Access

Low-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 ...

A self-learning whale optimization algorithm based on reinforcement learning for a dual-resource flexible job shop scheduling problem

Manafi, Ehsan; Domenech Léga, Bruno; Tavakkoli Moghaddam, Reza; Ranaboldo, Matteo (Elsevier, 2025-08)
Article
Open Access

One of the key areas in which production systems researchers are working these days is to find advanced optimization algorithms to efficiently schedule activities in manufacturing systems, which requires more sophisticated ...
