    • Particle-cluster aggregation with dipolar interactions 

      Pastor Satorras, Romualdo; Rubí Capaceti, José Miguel (1995-06)
      Article
      Accés obert
      The properties of aggregates generated from an off-lattice, two-dimensional, particle-cluster aggregation model with dipolar interparticle interactions have been investigated. The fractal dimension seems to be a monotonically ...

    • Peachy Parallel Assignments (EduHPC 2018)

(Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés obert
      Peachy Parallel Assignments are a resource for instructors teaching parallel and distributed programming. These are high-quality assignments, previously tested in class, that are readily adoptable. This collection of ...

    • Perturbation of the sierpinski antenna to allocate the operating bands 

      Puente Baliarda, Carles; Romeu Robert, Jordi; Bartolomé, R; Pous Andrés, Rafael (Institution of Electrical Engineers, 1996-11)
      Article
      Accés obert
      A scheme for modifying the spacing between the bands of the Sierpinski antenna is introduced. Experimental results of two novel designs of fractal antennas suggest that the fractal structure can be perturbed to enable the ...

    • Predictability of the monthly North Atlantic Oscillation index based on fractal analyses and dynamic system theory 

      Martínez Santafé, Maria Dolors; Lana Pons, Francisco Javier; Burgueño, August; Serra de Larrocha, Carina (University of Thechnology and Agriculture Nicholas Copernicus University, 2010-03)
      Article
      Accés obert

    • Premio EITP'98 para las Antenas Fractales 

      Prieto, Carlos; Puente Baliarda, Carles; Romeu Robert, Jordi; Cardama Aznar, Ángel (Escola Tècnica Superior d'Enginyers de Telecomunicació de Barcelona, 1999)
      Article

    • Quantum particles in fractal external potential 

      Amorós Trepat, Marc (Universitat Politècnica de Catalunya, 2021-06-28)
      Treball Final de Grau
      Accés obert
      The Schrödinger equation gives us a time evolution of the wave function of a certain quantum system, thus we obtain a mathematical description of this system. This project focuses on solving it numerically, using the exact ...

    • Richmyer-Meshkov and Rayleigh-Taylor turbulent mixing fronts and instabilities 

      Redondo Apraiz, José Manuel; Garzón Bedoya, Germán; Rozanov, V.B.; Gushkov, S. (Universidad Complutense de Madrid (UCM), 2010)
      Comunicació de congrés
      Accés obert
      Plume and Jets are released in an enclosed volume of water and depending on the initial and environmental conditions, the global mixing efficiency of the overall process is measured. The behaviour of individual plumes is ...

    • SAR Analysis of the ocean surface : aplication to the NW mediterranean marine pollution and dynamic features 

      Redondo Apraiz, José Manuel; Platonov, A.; Grau Barceló, Joan (Tempus Publications, 2009)
      Text en actes de congrés
      Accés obert
      The interaction between multiple scales in nature and mainly in turbulent flows produces fractals or multifractal structures. We use multi-fractal analysis to investigate the scales and influence of stratification in ...

    • The ECSEL FRACTAL Project: A cognitive fractal and secure edge based on a unique open-safe-reliable-low power hardware platform 

      Lojo, Aizea; Rubio, Leire; Ruano, Jesus Miguel; Mascio, Tania Di; Pomante, Luigi; Ferrari, Enrico; Garcìa Vega, Ignacio; Gürkaynak, Frank K.; Labayen Esnaola, Mikel; Orani, Vanessa; Abella Ferrer, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Comunicació de congrés
      Accés obert
      The objective of the FRACTAL project is to create a new approach to reliable edge computing. The computing node will be the building block of scalable Internet of Things (from Low Computing to High Computing Edge Nodes). ...

    • The fractal dimension of SAT formulas 

      Ansótegui Gil, Carlos; Bonet Carbonell, M. Luisa; Giráldez Crú, Jesús; Levy Díaz, Jordi (Springer, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Modern SAT solvers have experienced a remarkable progress on solving industrial instances. Most of the techniques have been developed after an intensive experimental process. It is believed that these techniques exploit ...

    • The maximum entropy principle and the nature of fractals 

      Pastor Satorras, Romualdo; Wagensberg Lubinski, Jorge (1998-06-19)
      Article
      Accés obert
      We apply the Principle of Maximum Entropy to the study of a general class of deterministic fractal sets. The scaling laws peculiar to these objects are accounted for by means of a constraint concerning the average content ...

    • Turbulence behind 3D multi-scale sparse grids
