  • Perceptual maps to aggregate assessments from different rating profiles: A hesitant fuzzy linguistic approach 

    Abuasaker, Walaa; Nguyen, Jennifer; Ruiz Vegas, Francisco Javier; Sánchez Soler, Monica; Agell, Núria (Elsevier, 2023-11)
    Article
    Open Access
    In decision making environments under uncertainty, assessments are frequently expressed in linguistic terms. When people express their opinions using linguistic terms, the meanings ascribed to these terms may not always ...
  • Microbiome compositional data analysis for survival studies 

    Pujolassos, Meritxell; Susín Sánchez, Antonio; Calle Rosingana, M. Luz (Oxford University Press, 2024-04-25)
    Article
    Open Access
    The growing interest in studying the relationship between the human microbiome and our health has also extended to time-to-event studies where researchers explore the connection between the microbiome and the occurrence ...
  • Dual-dataset deep learning for improved forest fire detection: A novel hierarchical domain-adaptive dearning approach 

    El Madafri, Ismail; Peña Carrera, Marta; Olmedo Torre, Noelia (Multidisciplinary Digital Publishing Institute (MDPI), 2024-02-08)
    Article
    Open Access
    This study introduces a novel hierarchical domain-adaptive learning framework designed to enhance wildfire detection capabilities, addressing the limitations inherent in traditional convolutional neural networks across ...
  • An a priori error analysis of a problem involving mixtures of continua with gradient enrichment 

    Bazarra, Noelia; Fernández García, José Ramón; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón; Magaña Centelles, Marc (2024-04-01)
    Article
    Restricted access - publisher's policy
    In this work, we study a strain gradient problem involving mixtures. The variational formulation is written as a first-order in time coupled system of parabolic variational equations. An existence and uniqueness result is ...
  • Research and numerical assessment of design and construction errors in the swimming pool facility structures 

    Skotnicka-Siepsiak, Aldona; Pawlowicz, Joanna A.; Szelag, Romuald; Krentowski, Janusz; Serrat Piè, Carles (Elsevier, 2024-05-01)
    Article
    Open Access
    Swimming pools are characterized by high humidity, high temperature, an aggressive environment caused by disinfection processes, high energy consumption, and extensive technical infrastructure. As a result, these facilities ...
  • Non-locality as a regularization mechanism in elastodynamics 

    Fernández García, José Ramón; Quintanilla de Latorre, Ramón (Elsevier, 2024-04-29)
    Article
    Open Access
    It is well known that the solutions to the elastodynamic problem do not satisfy continuous dependence properties on the initial values, and/or supply terms, when the elastic tensor fails to be positive. In fact, the behavior ...
  • Kahan-Hirota-Kimura maps preserving original cubic hamiltonians 

    Mañosa Fernández, Víctor; Pantazi, Chara (2024-05-02)
    Research report
    Open Access
    In this work we investigate the set of cubic Hamiltonian vector fields for which their associated Kahan-Hirota-Kimura maps preserve the original Hamiltonian function. We analyze these fields in R2 and R4. We also study a ...
  • Phase space analysis of sign-shifting interacting dark energy models 

    Halder, Sudip; Haro Cases, Jaume; Saha, Tapan; Pan, Supriya (American Physical Society, 2024-04-15)
    Article
    Open Access
    The theory of nongravitational interaction between a pressureless dark matter (DM) and dark energy (DE) is a phenomenologically rich cosmological domain which has received magnificent attention in the community. In the ...
  • An application to measure consensus on customers’ ratings using Hesitant Fuzzy Linguistic Term Sets 

    Abuasaker, Walaa; Nguyen, Jeniffer; Agell, Núria; Ruiz Vegas, Francisco Javier; Sánchez Soler, Monica (IOS Press, 2023)
    Conference lecture
    Open Access
    In this study, we propose a methodology using hesitant fuzzy linguistic term sets to aggregate rating values. The main idea is to define an integrated methodology for collaborative platforms involving individuals that use ...
  • Functional shift-induced degenerate transcritical neimark–sacker bifurcation in a discrete hypercycle 

    Fontich Julia, Ernest; Guillamon Grabolosa, Antoni; Perona García, Júlia; Sardanyes, Josep (World Scientific, 2024-03-20)
    Article
    Open Access
    In this paper, we investigate the impact of functional shifts in a time-discrete cross-catalytic system. We use the hypercycle model considering that one of the species shifts from a cooperator to a degrader. At the ...
  • Reverse engineering as a non-invasive examining method of the water tower brick structure condition 

    Pawlowicz, Joanna A.; Knyziak, Piotr; Krentowski, Janusz; Mackiewicz, Monika; Skotnicka-Siepsiak, Aldona; Serrat Piè, Carles (Elsevier, 2024-04-02)
    Article
    Open Access
    Reverse engineering is a method of obtaining information about the geometry of an existing object. To obtain such information, among others: 3D laser scanning is used. The result of measurements using this method is a point ...
  • Wind turbine gearbox condition monitoring using vibration data and Mel-Frequency Cepstral Coefficients 

    Velandia Cardenas, Cristian; Vidal Seguí, Yolanda; Pozo Montero, Francesc (Scipedia, 2023)
    Conference report
    Open Access
    A new methodology for wind turbine condition monitoring that utilizes vibration data and Mel-frequency cepstral coefficients (MFCCs) is being developed to accurately assess the condition of the wind turbine gearbox. ...
