  • Paun, Bruno; Bijnens, Bart; Iles, Tinen; Iaizzo, Paul A.; Butakoff, Constantine (Elsevier, 2017)
    Reparameterization of surfaces is a widely used tool in computer graphics known mostly from the remeshing algorithms. Recently, the surface reparameterization techniques started to gain popularity in the field of medical ...
  • Geers, Arjan; Larrabide, Ignacio, 1978-; Radaelli, Alessandro Guido; Bogunovic, Hrvoje; Kim, Minsuok; Gratama van Andel, Hugo A. F.; Majoie, Charles B. L. M.; VanBavel, E; Frangi Caregnato, Alejandro (American Society of Neuroradiology, 2011)
    Patient-specific simulations of the hemodynamics in intracranial aneurysms can be constructed by using image-based vascular models and CFD techniques. This work evaluates the impact of the choice of imaging technique on ...
  • Bijnens, Bart; García Cañadilla, Patricia, 1985-; Crispi Brillas, Fàtima; Cruz-Lemini, Mónica; Triunfo, Stefania; Nadal, Alfons; Valenzuela Alcaraz, Brenda; Rudenick, Paula A.; Gratacós Solsona, Eduard (Elsevier, 2015)
    Introduction: Intrauterine growth restriction (IUGR) due to placental insufficiency is associated with blood-flow redistribution in order to maintain perfusion to the brain. However, some hemodynamic parameters that might ...
  • Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    In a MIMO layered architecture, several codewords/nare transmitted from a multiplicity of antennas. Although the/nspectral efficiency is maximized if the rates of these codewords/nare separately controlled, the feedback ...
  • Friston, Karl; Breakspear, Michael; Deco, Gustavo (Frontiers Media, 2012)
    This paper considers state-dependent dynamics that mediate perception in the brain. In particular, it considers the formal basis of self-organized instabilities that enable perceptual transitions during Bayes-optimal ...
  • Overvliet, Krista E.; Karana, Elvin; Soto-Faraco, Salvador, 1970- (Elsevier, 2016)
    In many daily contexts, we prefer natural ‘materials’ over un-natural ones. Textiles embodied in garments that are worn on the body all day, or in bed sheets slept under every night touch us literally, on a daily basis. ...
  • Vazquez-Corral, Javier; Connah, David; Bertalmío, Marcelo (MDPI, 2014)
    Color camera characterization, mapping outputs from the camera sensors to an/nindependent color space, such as XY Z, is an important step in the camera processing/npipeline. Until now, this procedure has been primarily ...
  • Canadas Quesada, Francisco Jesus; Vera Candeas, Pedro; Ruiz Reyes, Nicolas; Carabias Orti, Julio J.; Cabanas Molero, Pablo (SpringerOpen, 2014)
    In this paper, unsupervised learning is used to separate percussive and harmonic sounds from monaural non-vocal polyphonic signals. Our algorithm is based on a modified non-negative matrix factorization (NMF) procedure ...
  • Liao, Ruizhi; Bellalta, Boris; Barceló Vicens, Jaume; Valls, Victor; Oliver Riera, Miquel (Springer, 2013)
    According to the ongoing IEEE 802.11ac amendment, the wireless network is about to embrace the gigabit-per-second raw data rate. Compared with previous IEEE standards, this significant performance improvement can be ...
  • Ramírez, Rafael,1966-; Maestre Gómez, Esteban; Pertusa, Antonio; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    We propose a novel approach to the task of identifying performers from their playing styles. We investigate how skilled musicians (Jazz saxophone players in particular) express and communicate their view of the musical and ...
  • Torre, Iratxe; González-Tendero, Anna; García Cañadilla, Patricia, 1985-; Crispi Brillas, Fàtima; García-García, Francisco; Bijnens, Bart; Iruretagoyena, Igor; Dopazo, Joaquín; Amat-Roldán, Iván; Gratacós Solsona, Eduard (Public Library of Science, 2014)
    Background: Intrauterine growth restriction (IUGR) induces fetal cardiac remodelling and dysfunction, which persists postnatally and may explain the link between low birth weight and increased cardiovascular mortality in ...
  • Imre Sarvari, Sebastian; Rodriguez López, Mérida; Nuñez-Garcia, Marta; Sitges, Marta; Sepulveda-Martinez, Alvaro; Camara, Oscar; Butakoff, Constantine; Gratacós Solsona, Eduard; Bijnens, Bart; Crispi Brillas, Fàtima (American Hearth Association, 2017)
    Fetal growth restriction (FGR) affects 5% to 10% of newborns and is associated with increased cardiovascular mortality in adulthood. We evaluated whether prenatal cardiovascular changes previously demonstrated in FGR persist ...
  • Bouayad-Agha, Nadjet; Casamayor, Gerard; Mille, Simon; Wanner, Leo (ACM Association for Computer Machinery, 2012)
    Team sports commentaries call for techniques that are able to select content and generate wordings to reflect the affinity of the targeted reader for one of the teams. The existing works tend to have in common that ...
  • Bailey, Delbert D.; Dalmau, Víctor; Kolaitis, Phokion G. (Elsevier, 2007)
    The complexity class PP consists of all decision problems solvable by polynomial-time probabilistic Turing machines. It is well known that PP is a highly intractable complexity class and that PP-complete problems are in ...
  • Mealla Cincuegrani, Sebastián; Jordà Puig, Sergi; Väljamäe, Aleksander (ACM Association for Computer Machinery, 2016)
    In this article, we evaluate b-Reactable, a digital music instrument that combines implicit physiology-based interaction through EEG and ECG, and explicit gestural interaction for sound generation and control. This ...
  • Bonet, Blai; Geffner, Héctor (Elsevier, 2001)
    In the AIPS98 Planning Contest, the hsp planner showed that heuristic search planners can be competitive with state-of-the-art Graphplan and sat planners. Heuristic search planners like hsp transform planning problems into ...
  • Wilhelmi Roca, Francesc; Barrachina Muñoz, Sergio; Bellalta, Boris; Cano Bastidas, Cristina; Jonsson, Anders, 1973-; Neu, Gergely (Elsevier, 2019)
    Spatial Reuse (SR) has recently gained attention to maximize the performance of IEEE 802.11 Wireless Local Area Networks (WLANs). Decentralized mechanisms are expected to be key in the development of SR solutions for ...
  • Serrà Julià, Joan; Kantz, Holger; Serra, Xavier; Andrzejak, Ralph Gregor (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Intuitively, music has both predictable and unpredictable components. In this work we assess this qualitative statement in a quantitative way using common time series models fitted to state-of-the-art music descriptors. ...
  • Rolls, Edmund T; Deco, Gustavo (Frontiers Media, 2011)
    Can decisions be predicted from brain activity? It is frequently difficult in neuroimaging studies to determine this, because it is not easy to establish when the decision has been taken. In a rigorous approach to this ...
  • Liu, Dan; Hu, Kai; Stork, Stefan; Herrmann, Sebastian; Kramer, Bastian; Cikes, Maja; Gaudron, Daniel; Knop, Stefan; Ertl, George; Bijnens, Bart; Weidemann, Frank (Public Library of Science, 2014)
    Objectives: Since diastolic abnormalities are typical findings of cardiac amyloidosis (CA), we hypothesized that speckle-tracking-imaging (STI) derived longitudinal early diastolic strain rate (LSRdias) could predict outcome ...
