  • Pérez Mayos, Laura; Farrús, Mireia; Adell, Jordi (Springer, 2019)
    Humanoid robots are already among us and they are beginning to assume more social and personal roles, like guiding and assisting people. Thus, they should interact in a human-friendly manner, using not only verbal cues but ...
  • 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 ...
  • Pal, Sougata; Oechsner, Simon; Bellalta, Boris; Oliver Riera, Miquel (IOS Press, 2013)
    Interconnecting multiple sensor networks is a relatively new research field which has emerged in the Wireless Sensor Network domain. Wireless Sensor Networks (WSNs) have typically been seen as logically separate, and few ...
  • 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 they ...
  • 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 ...
  • Ortega, Fabio J. M.; Giraldo, Sergio; Pérez Carrillo, Alfonso Antonio, 1977-; Ramírez, Rafael,1966- (Frontiers, 2019)
    Background: Expression is a key skill in music performance, and one that is difficult to address in music lessons. Computational models that learn from expert performances can help providing suggestions and feedback to ...
  • Vazquez-Corral, Javier; Finlayson, Graham D.; Bertalmío, Marcelo (Optical Society of America (OSA), 2020)
    Images captured under hazy conditions (e.g. fog, air pollution) usually present faded colors and loss of contrast. To improve their visibility, a process called image dehazing can be applied. Some of the most successful ...
  • 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 ...
