      Autebert, Jean-Michel; Gabarró Vallès, Joaquim (1985)
      Research report
      Open Access
      On se propose d'utiliser la méthode que P. Flajolet a décrit pour prouver l'ambiguité du langage de Goldstine [5], afin de prouver l'ambiguité d'une série de langages du même type. Ces langages sont tous des complémentaires ...
    • Concurrent AVL revisited: self-balancing distributed search trees 

      Bougé, Luc; Gabarró Vallès, Joaquim; Messeguer Peypoch, Xavier (1996-01)
      Research report
      Open Access
      We address the concurrent insertion and deletion of keys in binary almost balanced search trees (AVL trees). We show that this problem can be studied through the self-reorganization of distributed systems of processes ...
    • Concurrent rebalancing of AVL trees: a fine-grained approach 

      Bougé, Luc; Gabarró Vallès, Joaquim; Messeguer Peypoch, Xavier; Schabanel, Nicolas (1997-02)
      Research report
      Open Access
      We address the concurrent rebalancing of almost balanced binary search trees (AVL trees). Such a rebalancing may for instance be necessary after successive insertions and deletions of keys. We show that this ...
    • Concurrent rebalancing on hyperred-black trees 

      Gabarró Vallès, Joaquim; Messeguer Peypoch, Xavier; Daniel, Riu (1997-05)
      Research report
      Open Access
      The HyperRed-Black trees are a relaxed version of Red-Black trees accepting high degree of concurrency. In the Red-Black trees consecutive red nodes are forbidden. This restriction has been withdrawn in the Chromatic ...
    • Connections among non uniform models for problems requiring high amount of resources 

      Balcázar Navarro, José Luis; Gabarró Vallès, Joaquim (1985-11)
      Research report
      Open Access
      We characterize in terms of oracle Turing machines the classes defined by exponential lower bounds on some nonuniform complexity measures. After, we use the same methods to give a new characterization of classes defined ...
    • Continuous assessment in the evolution of a CS1 course: The pass rate/workload ratio

      Part of book or chapter of book
      Open Access
      The first programming course (Programming-1, CS1) in the Informatics Engineering Degree of the Facultat d'Informàtica de Barcelona was completely redesigned in 2006 in order to reinforce the learn-by- doing methodology. ...

      Considerable efforts have been put into making video content on the Web more accessible, searchable, and navigable by research on both textual and visual analysis of the actual video content and the accompanying metadata. ...
    • De menos a distinto: estudio de la implantación de R en las asignaturas del grado de estadística

      Conference lecture
      Open Access
      Los cursos de informática en las titulaciones que no son informáticas siempre pecan de falta de motivación y buenos resultados de los estudiantes. El argumento del estudiante acostumbra a ser: ¿A mí para que me servirá ...
    • De Menos a Distinto: Estudio de la Implantación de R en las asignaturas del grado de estadística 

      Baixeries i Juvillà, Jaume; Fairén González, Marta; Gabarró Vallès, Joaquim; Pasarella Sánchez, Ana Edelmira (2016)
      Conference report
      Open Access
      Teaching computer science in degrees that are not computer science related presents an important challenge: to motivate the students and to achieve good average grades. The student’s complaint is always based ...
    • Deciding bisimilarity is P-complete 

      Balcázar Navarro, José Luis; Gabarró Vallès, Joaquim; Santha, Miklos (1990)
      Research report
      Open Access
      On finite labelled transition systems, the problems of deciding strong bisimilarity, observation equivalence, and observation congruence are P-complete under many-one NC-reducibility. As a consequence, algorithms for ...
    • Design, implementation and evaluation of ParaDict, a data parallel library for dictionaries

      Research report
      Open Access
      ParaDict, a data parallel library for dictionaries having two different interfaces, is presented. The first interface is written in C* for data parallel users and the second interface in C, for users that want to use a ...
