    • Actividad al aire libre e intensidad de la luz solar como factor relevante en la prevención y control de la miopía 

      Bernabeu García, Víctor (Universitat Politècnica de Catalunya, 2021-06)
      Bachelor thesis
      Open Access
      Introducció: La miopia és un defecte que impedeix a la persona a veure amb claredat objectes llunyans. En els últims anys l'augment dràstic d'incidència i prevalença de miopia a nivell mundial, han impulsat l'avaluació de ...
    • Anàlisi bibliogràfica de l'ús de lents de contacte amb filtre d'absorbància selectiva 

      Gómez Artigas, Sara (Universitat Politècnica de Catalunya, 2019-01-25)
      Bachelor thesis
      Open Access
      Atès que l’ús i la varietat de dispositius electrònics s’estenen cada cop més i sabent que les pantalles són perjudicials per la visió, hem volgut esbrinar si les lents de contacte amb filtre d’absorbància selectiva poden ...
    • Building autonomic optical whitebox-based networks 

      Velasco Esteban, Luis Domingo; Sgambelluri, Andrea; Casellas Regi, Ramón; Gifre Renom, Lluís; Izquierdo Zaragoza, José Luis; Fresi, Francesco; Paolucci, Francesco; Martínez Rivera, Ricardo Victor; Riccardi, Emilio (Institute of Electrical and Electronics Engineers (IEEE), 2018-08-01)
      Article
      Open Access
      Disaggregation at the optical layer is expected to bring benefits to network operators by enriching the offering of available solutions and enabling the deployment of optical nodes that better fit their needs. In this ...
    • Genetic optimization Invents non-Hermitian potentials for Asymmetric Reflectivity 

      Ahmed Waseem, Waqas Waseem; Herrero Simon, Ramon; Botey Cumella, Muriel; Wu, Ying; Staliunas, Kestutis (2020-08)
      Research report
      Open Access
      We propose a general design strategy based on genetic optimization to realize asymmetric reflectivity in periodic and non-periodic planar structures containing dielectric and gain-loss layers. By means of an optimization ...
    • Inverse-design of non-Hermitian potentials for on-demand asymmetric reflectivity 

      Ahmed Waseem, Waqas Waseem; Herrero Simon, Ramon; Botey Cumella, Muriel; Wu, Ying; Staliunas, Kestutis (2021-05-24)
      Article
      Open Access
      We propose a genetic algorithm-assisted inverse design approach to achieve ‘ondemand’ light transport in periodic and non-periodic planar structures containing dielectric and gain-loss layers. The optimization algorithm ...
    • On the benefits of probabilistic constellation shaping in Flex-Grid/MCF dynamic optical backbone networks 

      Perelló Muntan, Jordi; Gené Bernaus, Joan M.; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      In this paper, we propose a novel methodology for estimating the worst-case spectral efficiency (b/s/Hz) of end-to-end paths across a Multi-Core Fiber (MCF)-enabled Flex-Grid optical network, accounting for physical link ...
    • Reflector design from radiance distributions 

      Patow, Gustavo Ariel; Pueyo Sandez, Francesc Xavier; Vinacua Pla, Álvaro (Institute for Applied Mathematics and Information Technology, 2004-12)
      Article
      Restricted access - publisher's policy
      This paper proposes a technique for the design of reflector shapes from prescribed optical properties (far field radiance distribution) and geometrical constraints, which is of high importance in the field of Lighting ...
