  • Central configurations in the five-body problem: rhombus plus one 

    Lino Cornelio, J.; Alvarez Ramírez, Martha; Cors Iglesias, Josep Maria (2021-05-20)
    Article

    We show the existence of central configurations in the planar five-body problem where four bodies are located at the vertices of a rhombus, called rhombus plus one central configurations. Concretely we prove analytically ...
  • On anonymous and weighted voting systems 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer Nature, 2021-04-27)
    Article

    Many bodies around the world make their decisions through voting systems in which voters have several options and the collective result also has several options. Many of these voting systems are anonymous, i.e., all voters ...
  • Convolutional neural network for wind turbine failure classification based on SCADA data 

    Puruncajas Maza, Bryan; Alava, Winter; Encalada-Dávila, Ángel; Tutivén Gálvez, Christian; Vidal Seguí, Yolanda (2021-09)
    Article
    Open Access
    As a renewable energy source and an alternative to fossil fuels, the wind power industry is growing rapidly. However, due to harsh weather conditions, wind turbines (WT) still face many failures that raise the price of ...
  • Wind turbine multi-fault detection based on SCADA data via an AutoEncoder 

    Encalada-Dávila, Ángel; Tutivén Gálvez, Christian; Puruncajas Maza, Bryan; Vidal Seguí, Yolanda (2021-09)
    Article
    Open Access
    Nowadays, wind turbine fault detection strategies are settled as a meaningful pipeline to achieve required levels of efficiency, availability, and reliability, considering there is an increasing installation of this kind ...
  • Weak null, necessary defender and necessary detractor players: characterizations of the Banzhaf and the Shapley bisemivalues 

    Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (Springer, 2021-06-16)
    Article
    Restricted access - publisher's policy
    We focus on bicooperative games, a variation of the classic cooperative games and, in particular, on the Banzhaf and the Shapley bisemivalues defined on these games. We consider three special classes of players: weak null, ...
  • On the axiomatic characterization of the coalitional multinomial probabilistic values 

    Carreras Escobar, Francisco; Puente del Campo, María Albina (Springer Nature, 2021-05-13)
    Article
    Restricted access - publisher's policy
    The coalitional multinomial probabilistic values extend the notion of multinomial probabilistic value to games with a coalition structure, in such a way that they generalize the symmetric coalitional binomial semivalues ...
  • Triangular Gross-Pitaevskii breathers and Damski-Chandrasekhar shock waves 

    Olshanii, Maxim; Deshommes, Dumesle; Gonchenko, Marina; Dunjko, Vedran; Astrakharchik, Grigori (2021-01-01)
    Article
    Open Access
    The recently proposed map [arXiv:2011.01415] between the hydrodynamic equations governing the two-dimensional triangular cold-bosonic breathers [Phys. Rev. X 9, 021035 (2019)] and the high-density zero-temperature triangular ...
  • Ageing of an oscillator due to frequency switching 

    Bonet Revés, Carles; Jeffrey, Mike R.; Martín de la Torre, Pablo; Olm Miras, Josep Maria (2021-11-01)
    Article
    Restricted access - publisher's policy
    If an oscillator is driven by a force that switches between two frequencies, the dynamics it exhibits depends on the precise manner of switching. Here we take a one-dimensional oscillator and consider scenarios in which ...
  • The dilating method to obtain dense cayley digraphs on finite abelian groups 

    Aguiló Gost, Francisco de Asis L.; Fiol Mora, Miquel Àngel; Pérez Mansilla, Sonia (2021-01-01)
    Article
    Open Access
    A geometric method for obtaining an infinite family of Cayley digraphs of constant density on finite abelian groups is presented. The method works for any given degree d ≥ 2, and it is based on consecutive dilates of a ...
  • Data-flow driven optimal tasks distribution for global heterogeneous systems 

    García Almiñana, Jordi; Aguiló Gost, Francisco de Asis L.; Asensio Garcia, Adrian; Simó Mezquita, Ester; Zaragoza Monroig, M. Luisa; Masip Bruin, Xavier (Elsevier, 2021-07)
    Article
    Open Access
    As a result of advances in technology and highly demanding users expectations, more and more applications require intensive computing resources and, most importantly, high consumption of data distributed throughout the ...
  • Mathematics training in engineering degrees: an intervention from teaching staff to students 

    López-Díaz, María Teresa; Peña Carrera, Marta (Multidisciplinary Digital Publishing Institute (MDPI), 2021-06-23)
    Article
    Open Access
    There has always been a great concern about the teaching of mathematics in engineering degrees. This concern has increased because students have less interest in these studies, which is mainly due to the low motivation of ...
  • SARS-CoV-2 transmission in students of public schools of Catalonia (Spain) after a month of reopening 

    Llupià, Anna; Borràs Santos, Alícia; Utzet Sadurní, Mireia; Guinovart Florensa, Caterina; Moriña, David; Puig Sadurní, Joaquim (Public Library of Science (PLOS), 2021-05-12)
    Article
    Open Access
    SARS-CoV-2 transmission within schools and its contribution to community transmission are still a matter of debate. Methods A retrospective cohort study in all public schools in Catalonia was conducted using publicly ...
