  • Bayesian Analysis of the Heterogeneity of Literary Style 

    Font Valverde, Martí; Puig Oriol, Xavier; Ginebra Molins, Josep (2016-07)
    Article
    Accés obert
    We proposed statistical analysis of the heterogeneity of literary style in a set of texts that simultaneously use different stylometric characteristics, like word length and the frequency of function words. The data set ...
  • Efficient heuristics for the parallel blocking flow shop scheduling problem 

    Ribas Vila, Immaculada; Companys Pascual, Ramon; Tort-Martorell Llabrés, Xavier (2017-05-15)
    Article
    Accés restringit per política de l'editorial
    We consider the NP-hard problem of scheduling n jobs in F identical parallel flow shops, each consisting of a series of m machines, and doing so with a blocking constraint. The applied criterion is to minimize the makespan, ...
  • How can SMEs benefit from big data? Challenges and a path forward 

    Coleman, Shirley; Goeb, Rainer; Manco, Giuseppe; Pievatolo, Antonio; Tort-Martorell Llabrés, Xavier; Reis, Marco Seabra (2016-10-01)
    Article
    Accés restringit per política de l'editorial
    Big data is big news, and large companies in all sectors are making significant advances in their customer relations, product selection and development and consequent profitability through using this valuable commodity. ...
  • Global and local distance-based generalized linear models 

    Boj, Eva; Caballé, Adrià; Delicado Useros, Pedro Francisco; Esteve, Anna; Fortiana, Josep (2016-03)
    Article
    Accés obert
    This paper introduces local distance-based generalized linear models. These models extend (weighted) distance-based linear models first to the generalized linear model framework. Then, a nonparametric version of these ...
  • Herbivores, saprovores and natural enemies respond differently to within-field plant characteristics of wheat fields 

    Caballero López, Berta; Blanco Moreno, José M.; Pujade Villar, Juli; Ventura, Daniel; Sánchez Espigares, Josep Anton; Sans Serra, Francesc Xavier (2016-05-26)
    Article
    Accés restringit per política de l'editorial
    Understanding ecosystem functioning in a farmland context by considering the variety of ecological strategies employed by arthropods is a core challenge in ecology and conservation science. We adopted a functional approach ...
  • A unified approach to authorship attribution and verification 

    Puig Oriol, Xavier; Font Valverde, Martí; Ginebra Molins, Josep (2016)
    Article
    Accés obert
    In authorship attribution, one assigns texts from an unknown author to either one of two or more candidate authors by comparing the disputed texts with texts known to have been written by the candidate authors. In authorship ...
  • Discussion of “Analysis of spatio-temporal mobile phone data: a case study in the metropolitan area of Milan” by Piercesare Secchi, Simone Vantini and Valeria Vitelli 

    Delicado Useros, Pedro Francisco (2015-05-21)
    Article
    Accés obert
    The paper under discussion is a very well-written and interesting piece of work by Secchi et al. (2015) dealing with spatio-temporal data on mobile phone use in the area of Milan. I congratulate the authors for such a ...
  • Optimal level sets for bivariate density representation 

    Delicado Useros, Pedro Francisco; Vieu, Philippe (2015-09-01)
    Article
    Accés restringit per política de l'editorial
    In bivariate density representation there is an extensive literature on level set estimation when the level is fixed, but this is not so much the case when choosing which level is (or which levels are) of most interest. ...
  • Comparison between mathematical models for roughness obtained in test machine and in industrial machine in semifinish honing processes 

    Buj Corral, Irene; Vivancos Calvet, Joan; Rodero de Lamo, Lourdes; Marco Almagro, Lluís (2015-12)
    Article
    Accés obert
    In the present work second order mathematical models for semifinish honing are presented for average roughness Ra as a function of abrasive stone characteristics and honing parameters. Several tests were performed in both ...
  • Explaining the Importance of Variability to Engineering Students 

    Grima Cintas, Pedro; Rodero de Lamo, Lourdes; Tort-Martorell Llabrés, Xavier (2015-07-09)
    Article
    Accés obert
    One of the main challenges of teaching statistics to engineering students is to convey the importance of being conscious of the presence of variability and of taking it into account when making technical and managerial ...
