  • Fostering sustainability and critical thinking through debate: a case study 

    Rodríguez Dono, Alfonso; Hernández Fernández, Antonio (2021-06)
    Article
    Open Access
    Transversal competences such as sustainability or critical thinking have become more important in the last decades in University teaching. The objective of this article is to assess the effectiveness of debate as a teaching ...
  • Qualitative and quantitative examples of natural and artificial phenomena 

    Hernández Fernández, Antonio (2021-05-24)
    Article
    Restricted access - publisher's policy
    The dichotomy between the qualitative and the quantitative has been a classic throughout the history of science. As will be seen, this dichotomy permeates all ontological levels of reality. In this work, phenomenological ...
  • Knowledge-based segmentation to improve accuracy and explainability in non-technical losses detection 

    Calvo Ibáñez, Albert; Coma Puig, Bernat; Carmona Vargas, Josep; Arias Vicente, Marta (2020-10-30)
    Article
    Open Access
    Utility companies have a great interest in identifying energy losses. Here, we focus on Non-Technical Losses (NTL), which refer to losses caused by utility theft or meter errors. Typically, utility companies resort to ...
  • Bounds of the sum of edge lengths in linear arrangements of trees 

    Ferrer Cancho, Ramon; Gómez Rodríguez, Carlos; Esteban Ángeles, Juan Luis (Institute of Physics (IOP), 2021-02-11)
    Article
    Restricted access - publisher's policy
    A fundamental problem in network science is the normalization of the topological or physical distance between vertices, which requires understanding the range of variation of the unnormalized distances. Here we investigate ...
  • Distinct flavors of Zipf's law and its maximum likelihood fitting: Rank-size and size-distribution representations 

    Corral Cano, Álvaro; Serra Mochales, Isabel; Ferrer Cancho, Ramon (American Institute of Physics (AIP), 2020-11-10)
    Article
    Open Access
    In recent years, researchers have realized the difficulties of fitting power-law distributions properly. These difficulties are higher in Zipfian systems, due to the discreteness of the variables and to the existence of ...
  • Reappraising the distribution of the number of edge crossings of graphs on a sphere 

    Alemany Puig, Lluís; Mora Giné, Mercè; Ferrer Cancho, Ramon (Institute of Physics (IOP), 2020-08-01)
    Article

    Many real transportation and mobility networks have their vertices placed on the surface of the Earth. In such embeddings, the edges laid on that surface may cross. In his pioneering research, Moon analyzed the distribution ...
  • Weak-type and end-point norm estimates for Hardy operators 

    Boza Rocho, Santiago; Soria de Diego, Francisco Javier (2020-11)
    Article
    Restricted access - publisher's policy
    We explicitly calculate the best constants for weak-type and other end-point estimates for the Hardy operator and its adjoint. In particular, we find the right value for decreasing power weights, fixing some previously ...
  • Refining indeterministic choice: Imprecise probabilities and strategic thinking 

    Castro Rabal, Jorge; Gabarró Vallès, Joaquim; Serna Iglesias, María José (2020-11)
    Article
    Open Access
    Often, uncertainty is present in processes that are part of our routines. Having tools to understand the consequences of unpredictability is convenient. We introduce a general framework to deal with uncertainty in the realm ...
  • Is classroom gamification opposed to performance? 

    Hernández Fernández, Antonio; Olmedo Torre, Noelia; Peña Carrera, Marta (2020-11-28)
    Article
    Open Access
    Learning through digital media is currently considered as a mixture of methodologies that aim to approach the reality of students to motivate them. Gamification emerges as one of the pedagogical methodologies on the rise ...
  • Optimal coding and the origins of Zipfian laws 

    Ferrer Cancho, Ramon; Bentz, Christian; Seguin, Caio (Informa UK (Taylor & Francis), 2020-07-24)
    Article
    Restricted access - publisher's policy
    The problem of compression in standard information theory consists of assigning codes as short as possible to numbers. Here we consider the problem of optimal coding – under an arbitrary coding scheme – and show that it ...
  • Edge crossings in random linear arrangements 

    Alemany Puig, Lluís; Ferrer Cancho, Ramon (Institute of Physics (IOP), 2020-02-19)
    Article
    Open Access
    In spatial networks vertices are arranged in some space and edges may cross. When arranging vertices in a 1D lattice edges may cross when drawn above the vertex sequence as it happens in linguistic and biological networks. ...
  • Cap a l'educació tecnològica 

    Hernández Fernández, Antonio (Institut d'Estudis Catalans (IEC), 2020-11)
    Article
    Open Access
    En aquest article s’apunta la necessitat d’una educació tecnològica que inclogui la filosofia de la tecnologia i la reflexió tecnoètica a l’educació secundària obligatòria, en la línia del pensament bungeà, i que vagi més ...
