Realizations of perturbations of an observable pair with prescribed indices
(Elsevier, 2011)
Article
Accés restringit per política de l'editorialIt is well known that, when a full rank observable pair (C,A) is slightly perturbed, the new observability indices k′ are majorized by the initial ones k, k≻k′. Conversely, any indices k′ majorized by k can be obtained by ... -
Segregació de l’estudiantat en els graus d’enginyeria
(OmniaScience, 2023-03)
Comunicació de congrés
Accés obertL’estudiantat dels graus d’enginyeria és majoritàriament blanc i masculí, mentre que altres grups com les dones o els estudiants de diferents ètnies i orígens continuen estant infrarepresentats. Aquestes desigualtats sovint ... -
Should teaching guides be used as indicators of gender dimension in a university degree?
(Technological University Dublin (TU Dublin), 2023)
Comunicació de congrés
Accés obertIn order to achieve a truly equality society, universities are making significant efforts towards gender mainstreaming. One of the main pillars of this approach is the implementation of a gender dimension in teaching. To ... -
Simultaneous versal deformations of endomorphisms and invariant subspaces
(2004)
Article
Accés obertWe study the set M of pairs (f; V ), defined by an endomorphism f of Fn and a d- dimensional f–invariant subspace V . It is shown that this set is a smooth manifold that defines a vector bundle on the Grassmann manifold. ... -
Stability of (A,B)-invariant subspaces
(2005)
Article
Accés obertGiven a pair of matrices (A;B) we study the stability of their invariant subspaces from the geometry of the manifold of quadruples (A;B; S; F) where S is an (A;B)-invariant subspace and F is such that (A + BF)S ½ S. In ... -
State canonical form for a class of uncontrollable linear systems
(Taylor & Francis, 2019-10-16)
Article
Accés obertWe tackle the obtaining of canonical forms for classifying linear control systems with regard to changes in the state variables. Although it was solved in the 1980s for controllable systems, it is still an open problem for ... -
STEM students’ perception of gender mainstreaming in teaching: the development of a measuring tool
(2019)
Comunicació de congrés
Accés obertThis study assesses the development process of a tool to measure students’ perceptions of gender mainstreaming in STEM (Science, Technology, Engineering and Mathematics) studies. Within the framework of a pilot project ... -
Structural stability of (C,A)-marked and observable subspaces
(2005)
Article
Accés obertGiven an observable pair of matrices (C;A) we consider the manifold of (C;A)-invariant and observable subspaces having a fixed Brunovsky- Kronecker structure. Using Arnold’s techniques we obtain the explicit form of a ... -
Structural stability of planar bimodal linear systems
(2014-01-01)
Article
Accés obertStructural stability ensures that the qualitative behavior of a system is preserved under small perturbations. We study it for planar bimodal linear dynamical systems, that is, systems consisting of two linear dynamics ... -
Structural stability of planar bimodal linear systems
(American Institute of Physics (AIP), 2013)
Text en actes de congrés
Accés obertWe consider bimodal linear dynamical systems consisting of two linear dynamics acting on each side of a given hyperplane, assuming continuity along the separating hyperplane. Focusing in the planar case, we describe which ... -
The intersection of sex and field: an examination of career choice factors and dropout intentions in STEM and non-STEM degrees
(Taylor & Francis Group, 2024-02-15)
Article
Accés restringit per política de l'editorialThe under-representation of women in male-dominated STEM fields is a worldwide concern. However, there are other academic fields, like some non-STEM degrees, where female students are over-represented. Previous research ... -
The wildfire dataset: enhancing deep learning-based forest fire detection with a diverse evolving open-source dataset focused on data representativeness and a novel multi-task learning approach
(2023-08-22)
Article
Accés obertThis study explores the potential of RGB image data for forest fire detection using deep learning models, evaluating their advantages and limitations, and discussing potential integration within a multi-modal data context. ... -
t’STEAM: acompañar la vocación tecnológica en mujeres de secundaria
(2018)
Text en actes de congrés
Accés obertEl proyecto piloto t'STEAM coordinado por el l'Institut de Ciències de l'Educació (ICE) de la Universitat Politècnica de Catalunya. UPC·BarcelonaTech (UPC) propone utilizar la mentoría entre mujeres como herramienta para ... -
Un enfoque innovador basado en inteligencia artificial para la detección automática de incendios forestales
(OmniaScience, 2024-01)
Comunicació de congrés
Accés obertEn una era donde el cambio climático exacerba la frecuencia y severidad de los incendios forestales, avanzar en los métodos de detección temprana es crítico para la preservación de los ecosistemas y la seguridad de las ... -
Use of reduced forms in the disturbance decoupling problem
(Elsevier, 2009-03)
Article
Accés restringit per política de l'editorialSpecific algorithms, such as those involving the supremal of the invariant subspaces contained in a suitable subspace, are known to be able to test whether a disturbance decoupling problem (DDP) is solvable. Here, by ...
