  • Wind profile prediction using linear Markov chains: A linear algebra approach 

    García Planas, María Isabel; Gongadze, Tornike (2018-02)
    Article
    Open Access
    To predict the future wind speed and wind direction is of relevance to the wind industry to maximize the power generation. In this regards, this article describes a methodology for the construction of predictive models ...

  • Bounding the distance from a reachable/controllable equisingular switched linear system to the set of non-reachable/uncontrollable ones 

    Magret Planas, Maria dels Dolors (2016)
    Article
    Open Access
    No necessary and sufficient condition for reachability of switched linear singular systems has been found in general, but only in the case of the so-called “equisingular systems”. In this case, it is possible to obtain an ...

  • Concatenated linear systems over rings and their application to construction of concatenated families of convolutional codes 

    deCastro Garcia, Noemi; García Planas, María Isabel (Elsevier, 2017-01-01)
    Article
    Restricted access - publisher's policy
    © 2017 Elsevier Inc. We present a generalization of the theory of concatenated linear systems to commutative rings with identity. Moreover, we highlight sufficient conditions to obtain reachable and observable concatenated ...

  • Analizing exact controllability of l-order linear systems 

    García Planas, María Isabel (WSEAS Press, 2017-01-01)
    Article
    Open Access
    In recent years there has been growing interest in the descriptive analysis of l-order time invariant linear dynamical system xl = Al-1xl-1 ++ A0x0 where Ai are square complex matrices and xi denotes the i-th derivative ...

  • Monomial codes seen as invariant subspaces 

    García Planas, María Isabel; Magret Planas, Maria dels Dolors; Um, Laurence Emilie (2017)
    Article
    Open Access
    It is well known that cyclic codes are very useful because of their applications, since they are not computationally expensive and encoding can be easily implemented. The relationship between cyclic codes and invariant ...

  • La competencia de sostenibilidad y compromiso social en la asignatura de álgebra lineal en los grados de ingeniería 

    García Planas, María Isabel; Taberna Torres, Judit (2017)
    Article
    Open Access
    Los estudios de grado de ingeniería deben preparar al futuro profesional de manera que sepa abstraer y modelar la realidad de una situación determinada, de manera que sea capaz de encontrar la mejor solución tanto desde ...

  • Uso de blogs en la asignatura de dibujo en los estudios dUe grado de arquitectura 

    García Planas, María Isabel; Taberna Torres, Judit; Domínguez García, Santiago (2017-07-10)
    Article
    Open Access
    Con el fin de contribuir al incremento de la eficiencia del proceso enseñanza-aprendizaje en la educación superior, hemos realizado una experiencia de innovación docente consistente en el uso de blogs educativos como ...

  • Cyclic-union operation to obtain latin squares 

    García Planas, María Isabel; Roca Borrego, Didac (2017)
    Article
    Open Access
    With the power that has taken the information technologies, one has developed the study and research about cryptography, and cryptanalysis, in which Latin squares are ideal candidates for being used in cryptographic systems ...

    García Planas, María Isabel (WSEAS Press, 2017-05)
    Article
    Open Access
    In recent years there has been growing interest in the descriptive analysis of l -order time invariant linear dynamical system x l = A l system x l = A l where A i are square complex matrices and x i denotes the i-th ...

  • Bifurcation diagram of Saddle/Spiral bimodal linear systems 

    Ferrer Llop, Josep; Peña Carrera, Marta; Susín Sánchez, Antonio (2017-01-01)
    Article
    Open Access
    We complete the study of the bifurcations of saddle/spiral bimodal linear systems, depending on the respective traces T and t: one 2-codimensional bifurcation; four kinds of 1-codimensional bifurcations. We stratify the ...

  • On stability and controllability of multi-agent linear systems 

    García Planas, María Isabel; Tarragona, Sonia (2016-11)
    Article
    Open Access
    Recent advances in communication and computing have made the control and coordination of dynamic network agents to become an area of multidisciplinary research at the intersection of the theory of control systems, communication ...

  • Consensus stabilizability and exact consensus controllability of multi-agent linear systems 

    García Planas, María Isabel (2016-11)
    Article
    Open Access
    A goal in engineering systems is to try to control them. Control theory offers mathematical tools for steering engineered systems towards a desired state. Stabilizability and controllability can be studied under different ...
