Recent Submissions

  • Inducing braces and Hopf Galois structures 

    Crespo, Teresa; Gil Muñoz, Daniel; Río Doval, Ana; Vela del Olmo, Maria Montserrat (2023-09-01)
    Article
    Open Access
    Let p be a prime number and let n be an integer not divisible by p and such that every group of order np has a normal subgroup of order p. (This holds in particular for � > � .) Under these hypotheses, we obtain a one-to-one ...

  • Square-free OM computation of global integral bases 

    Guàrdia Rubies, Jordi; Nart Vinyals, Enric (2022-09-27)
    Article
    Open Access
    For a prime p, the OM algorithm finds the p-adic factorization of an irreducible polynomial f¿Z[x]¿¿Z[¿] in polynomial time. This may be applied to construct p-integral bases in the number field K defined by f. In this ...

  • Incorporating a study and research path into a statistics course for engineering students 

    Freixanet de la Iglesia, Maria Josep; Alsina Aubach, Montserrat; Bosch Casabò, Marianna (2022)
    Conference lecture
    Restricted access - publisher's policy
    This paper describes a teaching proposal in engineering education based on the introduction of a study and research path (SRP) in the subject of Statistics of a Bachelor’s Degree in ICT Systems Engineering. The conditions ...

  • How does noise affect our health? Analysing a project-based activity in statistics at secondary level 

    Freixanet de la Iglesia, Maria Josep; Alsina Aubach, Montserrat; Bosch Casabò, Marianna (2022)
    Conference lecture
    Open Access
    Teaching statistics through projects brings to life in the classroom aspects of working with data that are not usually part of traditional paper-and-pencil activities. There exists a generalized agreement about the positive ...

  • Left braces of size 8 p 

    Crespo Vicente, Teresa; Gil Muñoz, Daniel; Río Doval, Ana; Vela del Olmo, Maria Montserrat (2023)
    Article
    Open Access
    We describe all left braces aof size 8 p for an odd p diferent from 3 and 7.

  • A practical approach to statistics through SRP 

    Freixanet de la Iglesia, Maria Josep; Alsina Aubach, Montserrat; Bosch Casabò, Marianna (2022)
    Conference lecture
    Open Access
    The paper explains the design and the first part of the implementation of a project within the subject of Statistics with first year students in a Bachelor’s degree in ICT Systems Engineering in Manresa School of Engineering, ...

  • Service-learning in engineering: analysis of students experiences in development cooperation 

    Alsina Aubach, Montserrat; Alfonso Abella, María Pura; Sidki Rius, Nor; Bel Roset, Guillem; Gaona Boixader, Roger (2022)
    Conference lecture

  • ATD as an engine for evolution 

    Freixanet de la Iglesia, Maria Josep; Alsina Aubach, Montserrat; Bosch Casabò, Marianna (2022)
    Conference lecture
    Restricted access - publisher's policy
    This article explains the first steps of a teacher’s evolution from working with projects without following any theoretical frame to working with projects following the proposal of study and research paths from the ...

  • Valuative trees over valued fields 

    Alberich Carramiñana, Maria; Guàrdia Rubies, Jordi; Nart Vinyals, Enric; Roé Vallvé, Joaquim (Elsevier, 2023-01-15)
    Article
    Open Access
    For an arbitrary valued field (K, v) and a given extension v(K*) ¿¿ ¿ of ordered groups, we analyze the structure of the tree formed by all ¿-valued extensions of v to the polynomial ring K[x]. As an application, we find ...
