A note on the subgraphs of the (2×\infty)-grid
(2010-02)
Article
Accés restringit per política de l'editorialWe give a linear-time algorithm checking whether a graph is a subgraph of the (2×k)-grid for some value of k. Our algorithm is based on a detailed characterization of the structure of such graphs. -
A note on the symmetric difference in lattices
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
Article
Accés obertThe paper introduces a definition of symmetric difference in lattices with negation, presents its general properties and studies those that are typical of ortholattices, orthomodular lattices, de Morgan and boolean algebras. -
A note on the symplectic topology of b-manifolds
(2017)
Article
Accés obertPoisson manifold (M2n; ) is b-symplectic if Vn is transverse to the zero section. In this paper we apply techniques native to Symplectic Topology to address questions pertaining to b-symplectic manifolds. We pro- vide ... -

A note on the two temperature theory with dual-phase-lag delay: some exact solutions
(Elsevier, 2009-10)
Article
Accés restringit per política de l'editorialIn this note we present exact solutions of two initial-boundary value problems (IBVP)s in the setting of a recently-introduced theory of heat conduction, wherein the two temperature theory of the late 1960s is merged ... -
A note on the use of supply-use tables in impact analyses
(Institut d'Estadística de Catalunya, 2012)
Article
Accés obertLittle attention has so far been paid to the problems inheren t in interpreting the meaning of results from standard impact analyses using symmetric input-outpu t tables. Impacts as well as drivers of these impacts ... -
A Note on the use of topology extensions for provoking instability in communication networks
(2004-03)
Report de recerca
Accés obertWe study some aspects of the instability of the last-in-first-out (LIFO) scheduling protocol in under-loaded packet-switched networks under the Adversarial Queueing Theory model [Borodin et al., Journal of the ACM, ... -
A note on upper bound formulations in limit analysis
(John Wiley & Sons, 2012-08-24)
Article
Accés restringit per política de l'editorialIn this paper we study some recent formulations for the computation of upper bounds in limit analysis. We show that a previous formulation presented by the authors does not guarantee the strictness of the upper bound, ... -
A note on Weak Stability Boundaries
(2006-12-08)
Article
Accés restringit per política de l'editorialThis paper is devoted to clarify the algorithmic definition of the weak stability boundary in the framework of the planar Restricted Three Body Problem. The role of the invariant hyperbolic manifolds associated to the ... -
A novel AC-AC converter based SiC for domestic induction cooking applications
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents the analysis and design of a new high frequency ac-ac converter applied to domestic induction heating. The proposed topology uses only four switches to control power. Converter operation is same as a ... -
