    • A cotangent bundle Hamiltonian tube theorem and its applications in reduction theory 

      Teixidó Román, Miguel (Universitat Politècnica de Catalunya, 2015-03-27)
      Tesi
      Accés obert
      The Marle-Guillemin-Sternberg (MGS) model is an extremely important tool for the theory of Hamiltonian actions on symplectic manifolds. It has been extensively used to prove many local results both in symplectic geometry ...

    • A Hamiltonian study of the stability and bifurcations for the satellite problem 

      Muñoz Lecanda, Miguel Carlos; Rodríguez Olmos, Miguel Andrés; Teixidó Román, Miguel (2015-10-01)
      Article
      Accés obert
      We study the dynamics of a rigid body in a central gravitational field modeled as a Hamiltonian system with continuous rotational symmetries following the geometric framework of Wang et al. Novelties of our work are the ...

    • Adaptive discontinuous zero sequence signal for modular multilevel converter applications 

      Antonio Ferreira, Abel; Gomis Bellmunt, Oriol; Teixidó Román, Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work proposes a technique to inject a discontinuous zero sequence signal (D-ZSS) into voltage modulation of the modular multilevel converter arms. The core of the technique is the clamping of the arm voltages to a ...

    • Grid power flow impact on the on-state losses of the modular multilevel converter 

      Ferreira, A. A.; Gomis Bellmunt, Oriol; Teixidó Román, Miguel (2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The efficiency of the Modular Multilevel Converters (MMC) makes it the preferable VSC solution for the HVdc field. The knowledge of its modus operandi and their devices it is extremely important to improve the MMC performance. ...

    • Hamiltonian methods in stability and bifurcations problems for artificial satellite dynamics 

      Teixidó Román, Miguel (Universitat Politècnica de Catalunya, 2011-03)
      Projecte Final de Màster Oficial
      Accés obert
      The dynamics of a rigid body in a central gravitational eld can be modelled by a Hamiltonian system with continuous symmetries implemented by an action of the group SO(3). Depending on the particular geometry of the body ...

    • HVDC-based modular multilevel converter in the STATCOM operation mode 

      Antonio Ferreira, Abel; Gomis Bellmunt, Oriol; Teixidó Román, Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In a futuristic vision, deeply interconnected ac and dc networks are expected, which would be restructured over the time in order to maximize the power transmission efficiency. In some grid configurations, grid-tied inverters ...

    • Role of Innate and Adaptive Cytokines in the Survival of COVID-19 Patients 

      Monserrat Sanz, Jorge; Gómez Lahoz, Ana; Ortega, Miguel A.; Sanz, José; Muñoz, Benjamin; Arévalo Serrano, Juan; Rodríguez, Jose Miguel; Gasalla, Jose María; Gasulla, Òscar; Arranz, Alberto; Fortuny Profitós, Jordi; Mazaira Font, Ferran; Teixidó Román, Miguel; Martínez Alonso, Carlos; Balomenos, Dimitri (2022-09-07)
      Article
      Accés obert
      SARS-CoV-2 is a new coronavirus characterized by a high infection and transmission capacity. A significant number of patients develop inadequate immune responses that produce massive releases of cytokines that compromise ...

    • The Hamiltonian tube of a cotangent-lifted action 

      Rodríguez Olmos, Miguel Andrés; Teixidó Román, Miguel (2017)
      Article
      Accés obert
      The Marle-Guillemin-Sternberg (MGS) form is local model for a neighborhood of an orbit of a Hamiltonian Lie group action on a symplectic manifold. One of the main features of the MGS form is that it puts simultaneously in ...
