    Myopia control with new designs of spectacle lenses is a flourishing area of research. The present work reviews the effectiveness of new designs (DIMSs, defocus-incorporated multiple segments; CARE, cylindrical annular ...
  • A novel three-dimensional sigma–delta modulation for high-switching-frequency three-phase four-wire active power filters 

    Lumbreras Carrasco, David; Zaragoza Bertomeu, Jordi; Lamich Arocas, Manuel; Berbel Artal, Néstor; Romero Cadaval, Enrique (2024-02-01)
    Article
    Open Access
    This article presents a new modulation technique called three-dimensional sigma–delta (3D-S¿ ) modulation for high-frequency three-leg four-wire voltage source converters (VSCs) that use wide-bandgap (WBG) semiconductors. ...

    Conference report
    Open Access
    The MELOA H2020 project proposes to develop a low-cost, easy-to-handle, wave resilient, multipurpose , multi-sensor, extra light surface drifter for use in all water environments: The WAVY drifters. The data products ...
  • Data acquisition differences between two AIS receiving antennas. 

    Mujal Colilles, Anna; Fonollosa Magrinyà, Jordi (2023)
    Conference report
    Restricted access - publisher's policy
    Raw AIS messages are key to interpret the validity of AIS messages used in science for maritime spatial planning purposes. The Barcelona School of Nautical Studies has hosted two AIS antennas, storing raw messages ...
  • Correlation study between the performance in different engineering courses and project-based courses 

    Bermejo Broto, Sandra; Bragós Bardia, Ramon; Rey Micolau, Francesc; Pegueroles Vallés, Josep R. (NTNU SEED, 2023)
    Conference lecture
    Open Access
    In a previous study, already published (Bragós, 2022), we analyzed the correlation between the University access mark to the engineering studies with the grades obtained in projectbased courses and in non-project-based ...
  • Data alternatives for marine efficiency monitoring 

    van der Meer, Ruurd; Phylip Jones, Geraint; Castells Sanabra, Marcel·la; Borén Altés, Clara; Torralbo Gavilán, Jordi; Ordás Jiménez, Santiago; Kiplimo, Robert (International Association of Maritime Universities, 2017)
    Book

    The implementation of measures to increase the energy efficiency of ships is not so successful as expected. A benchmark is needed to gain insight in the present state of the energy efficiency of ships. That can be used to ...
  • One-degree aerial device: control and experimental development 

    Acho Zuppa, Leonardo; Buenestado Caballero, Pablo; Pujol Vázquez, Gisela (Hindawi, 2024-02-10)
    Article
    Open Access
    The ball and beam experimental platform is an unstable nonlinear system widely used as a benchmark control setup for testing different controller approaches, especially for beginners on automatic control to improve their ...
  • Bisymmetric non-negative Jacobi matrix realizations 

    Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José; Marijuan López, Carlos; Mitjana Riera, Margarida; Pisonero Pérez, Miriam (Taylor & Francis Group, 2023-12-21)
    Article
    Restricted access - publisher's policy
    Within the symmetric inverse eigenvalue problem, the case of bisymmetric Jacobi matrices occupies a central place, since for any strictly monotone list of n real numbers there exists a unique bisymmetric Jacobi matrix ...
  • High frequency of antimicrobial drug resistance of diarrheagenic Escherichia coli in infants in Peru 

    Ochoa, Theresa J.; Ruiz Blazquez, Joaquim; Molina, Margarita; Valle Mendoza, Luis Javier del; Vargas Orihuela, Martha; Gil, Ana I.; Ecker, Lucie; Barletta, Francesca; Hall, Eric; Clearcy, Thomas; Lanata, Claudio F. (2009)
    Article
    Open Access
    In a prospective passive diarrhea surveillance cohort study of 1,034 infants of low socioeconomic communi- ties in Lima, Peru, we determined the prevalence and antimicrobial drug susceptibility of the diarrheagenic Escherichia ...
  • Reheating formulas in quintessential inflation via gravitational particle production 

    Haro Cases, Jaume (American Physical Society, 2024-01-15)
    Article
    Open Access
    We calculate the reheating temperature in scenarios where heavy particles are gravitationally produced during a phase transition. We explore two distinct situations: the decay of these particles both during and after the ...
  • Asymptotic spatial behavior for the heat equation on noncompact regions 

    Knops, Robin J.; Quintanilla de Latorre, Ramón (John Wiley & sons, 2024-01-16)
    Article
    Open Access
    We consider the isotropic initial boundary value problem for the heat equation on open regions with noncompact boundary and construct differential inequalities for a generalized heat flow measure defined over a spherical ...
  • LCL filter design for VSC-HVDC systems supplying passive grids 

    Albernaz Lacerda Freitas, Vinícius; Coury, Denis V.; Machado Monaro, Renato (Elsevier, 2017-11)
    Article
