  • Hoogendoorn, Corné; Sukno, Federico M.; Ordás, Sebastián; Frangi Caregnato, Alejandro (Springer, 2009)
    In this work we describe the usage of bilinear statistical models as a means of factoring the shape variability into two components attributed to inter-subject variation and to the intrinsic dynamics of the human heart. ...
  • Costalat, V.; Sánchez, M.; Ambard, D.; Thines, L.; Lonjon, N.; Nicoud, F.; Brunel, H.; Lejeune, J. P.; Dufour, H.; Bouillot, P.; Lhaldky, J. P.; Kouri, K.; Segnarbieux, F.; Mourage, C. A.; Lobostein, K.; Villa-Uriol, Maria-Cruz; Zhang, Chong; Frangi Caregnato, Alejandro; Mercier, G.; Bonafé, A.; Sarry, L.; Jourdan, F. (Elsevier, 2011)
    Background and purpose: Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength ...
  • Tulino, Antonia M.; Lozano Solsona, Àngel; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    We characterize the capacity-achieving input covariance for multi-antenna channels known instantaneously at the receiver and in distribution at the transmitter. Our characterization, valid for arbitrary numbers of antennas, ...
  • Lozano Solsona, Àngel (Institute of Electrical and Electronics Engineers (IEEE), 2003)
    The simultaneous use of multiple transmit and receive antennas can unleash very large capacity increases in rich multipath environments. Although such capacities can be approached by layered multi-antenna architectures ...
  • Huguet, Marina; Tobón Gómez, Catalina; Bijnens, Bart; Frangi Caregnato, Alejandro; Petit i Guinovart, Màrius (BioMed Central, 2009)
    Blunt chest traumas are a clinical challenge, both for diagnosis and treatment. The use of Cardiovascular Magnetic Resonance can play a major role in this setting. We present two cases: a 12-year-old boy and 45-year-old ...
  • Oubel, E.; De Craene, Mathieu; Hero, A.O.; Pourmorteza, A.; Huguet, Marina; Avegliano, G.; Bijnens B.H.; Frangi Caregnato, Alejandro (Elsevier, 2011)
    Image registration has been proposed as an automatic method for recovering cardiac displacement fields from Tagged Magnetic Resonance Imaging (tMRI) sequences. Initially performed as a set of pairwise registrations, these ...
  • Piella Fenoy, Gemma; De Craene, Mathieu; Bijnens B.H.; Tobón Gómez, Catalina, 1981-; Huguet, Marina; Avegliano, G.; Frangi Caregnato, Alejandro (Elsevier, 2010)
    Introducción y objetivos. Se ha señalado que, en la miocardiopatía hipertrófica (MCH), la desorganización de las fibras regionales da lugar a segmentos en los que la deformación es nula o está gravemente reducida, y que ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia; Herrera Boyer, Perfecto; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We present a new technique for audio signal comparison based on tonal subsequence alignment and its application to detect cover versions (i.e., different performances of the same underlying musical piece). Cover song ...
  • Jorrín-Abellán, Iván M.; Ruiz-Requies, Inés; Hernández Leo, Davinia; Villasclaras-Fernández, Eloy D.; Dimitriadis, Yannis; Rubia-Avi, Bartolomé; Asensio-Pérez, Juan I. (International Forum of Educational Technology & Society, 2006)
    This paper introduces Collage, a high-level IMS-LD compliant authoring tool that is specialized for CSCL (Computer-Supported Collaborative Learning). Nowadays CSCL is a key trend in elearning since it highlights the ...
  • Faridi, Azadeh; Palattella, Maria Rita; Lozano Solsona, Àngel; Dohler, Mischa; Boggia, Gennaro; Grieco, Luigi Alfredo; Camarda, Pietro (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Supported by IEEE 802.15.4 standardization activities, embedded networks have been gaining popularity in recent years. The focus of this paper is to quantify the behavior of key networking metrics of IEEE 802.15.4 ...
  • Hernández Leo, Davinia; Asensio-Pérez, Juan I.; Dimitriadis, Yannis (International Forum of Educational Technology & Society, 2005)
    The identification and integration of reusable and customizable CSCL (Computer Supported Collaborative Learning) may benefit from the capture of best practices in collaborative learning structuring. The authors have proposed ...
  • Hernández Leo, Davinia; Moreno, Verónica (2010)
    La Unidad de Apoyo a la Calidad y a la Innovación Docente de la Escuela Superior Politécnica (Universidad Pompeu Fabra) crea una Web para potenciar las experiencias innovadoras que responden a las necesidades y demandas ...
  • Serrà Julià, Joan; Serra, Xavier; Andrzejak, Ralph Gregor (Institute of Physics (IOP), 2009)
    There is growing evidence that nonlinear time series analysis techniques can be used to successfully characterize, classify, or process signals derived from realworld dynamics even though these are not necessarily deterministic ...
  • Bernardini, A.; Larrabide, Ignacio; Petrini, L.; Pennati, G.; Flore, E.; Kim, Minsuok; Frangi Caregnato, Alejandro (Taylor & Francis (Routledge), 2011)
    In the last few years, there has been a growing focus on faster computational methods to support clinicians in planning stenting procedures. This study investigates the possibility of introducing computational approximations ...
  • Pérez Sanagustín, Maria del Mar; Hernández Leo, Davinia; Santos Rodríguez, Patrícia; Sayago Barrantes, Sergio; Blat, Josep; Griffiths, Dai (International Association of Online Engineering (IAOE), 2008)
    Dialogic learning and interactive groups have proved to be a useful methodological approach applied in educational situations for lifelong adult learners. The principles of this approach stress the importance of dialogue ...
  • Pérez Sanagustín, Maria del Mar; Ramírez González, G.; Hernández Leo, Davinia; Muñoz Organero, Mario; Santos Rodríguez, Patrícia; Blat, Josep; Delgado Kloos, Carlos (Elsevier, 2011)
    One of the most relevant difficulties faced by first-year undergraduate students is to settle into the educational environment of universities. This paper presents a case study that proposes a computer-assisted collaborative ...
  • Faridi, Azadeh; Ephremides, Anthony (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We investigate the problem of finding minimum-distortion policies for streaming delay-sensitive but distortion-tolerant data. We consider cross-layer approaches which exploit the coupling between presentation and transport ...
  • Zhang, Chong; Villa-Uriol, Maria-Cruz; De Craene, Mathieu; Pozo Soler, José Ma. (José María); Macho, Juan M.; Frangi Caregnato, Alejandro; Universitat Pompeu Fabra (American Association of Physicists in Medicine (AAPM), 2011)
    Purpose: The objective of this study is to investigate the feasibility of detecting and quantifying 3D cerebrovascular wall motion from a single 3D rotational x-ray angiography (3DRA) acquisition within a clinically ...
  • Balocco, Simone; Basset, Olivier; Courbebaisse, Guy; Boni, Enrico; Frangi Caregnato, Alejandro; Tortoli, Piero; Cachard, Christian (Institute of Physics (IOP), 2010)
    Human arteries affected by atherosclerosis are characterized by altered wall viscoelastic properties. The possibility of noninvasively assessing arterial viscoelasticity in vivo would significantly contribute to the early ...
