  • Meditskos, Georgios; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Springer, 2017)
    We present a framework for semantic situation understand- ing and interpretation of multimodal data using Description Logics (DL) and rules. More precisely, we use DL models to formally describe contex- tualised ...
  • Nadeu Camprubí, Climent; Mariño Acebal, José B.; Farrús, Mireia (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), Universitat Politècnica de Catalunya, 2008)
    In this communication, the authors aim to describe their experience in a couple of optional STS courses taught at the school Telecom BCN (ETSETB) of the Universitat Politècnica de Catalunya (UPC). The first one is about ...
  • Fernandez-Lopez, Adriana; Sukno, Federico M. (SCITEPRESS, 2017)
    Speech is the most common communication method between humans and involves the perception of both auditory and visual channels. Automatic speech recognition focuses on interpreting the audio signals, but it has been ...
  • Hernando, Javier; Farrús, Mireia; Ejarque, Pascual; Garde, Ainara; Luque, Jordi; Comunicació presentada a: SECRYPT 2006, International Conference on Security and Cryptography, celebrada a Setúbal, Portugal, del 7 al 10 d'agost de 2006 (INSTICC Press, 2006)
    Prosodic information can be used successfully for automatic speaker recognition, although most of the speaker recognition systems use only short-term spectral features as voice information. In this work, prosody information ...
  • Andrzejak, Ralph Gregor; Ruzzene, Giulia; Malvestio, Irene (American Institute of Physics (AIP), 2017)
    Networks of coupled oscillators in chimera states are characterized by an intriguing interplay of synchronous and asynchronous motion. While chimera states were initially discovered in mathematical model systems, there ...
  • Albó Pérez, Laia; Gelpí Arroyo, Cristina (2017)
    This paper presents a case study of transforming an existing MOOC into a SPOC for being used in a campus course using a blended learning ap-proach with the aim of providing a reflection of the experience and reporting the ...
  • Albó Pérez, Laia; Hernández Leo, Davinia (2017)
    This paper presents a case study of integrating two external MOOCs in a face-to-face (f2f) summer course for high school students. The aim of the study is to explore the design challenges emerged from this blended learning ...
  • Rauschenberger, Maria; Schrepp, Martin; Cota, Manuel Pérez; Olschner, Siegfried; Thomaschewski, Jörg (Universidad Internacional de La Rioja (UNIR), 2003)
    Developer, manager and user feedback is needed to optimize products. Besides the basic Software qualities – usability and user experience are important properties for improving your product. Usability is well known and ...
  • Dzhambazov, Georgi Bogomilov; Sentürk, Sertan; Serra, Xavier (Computer Engineering Department, Bogaziçi University, 2014)
    We apply a lyrics-to-audio alignment state-of-the-art approach to polyphonic pieces from classical Turkish repertoire. A phonetic recognizer is employed, whereby each phoneme is assigned a hidden Markov model (HMM). Initially ...
  • Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (Computer Engineering Department, Bogaziçi University, 2014)
    Audio-score alignment is a multi-modal task, which facilitates many related tasks such as intonation analysis, structure analysis and automatic accompaniment. In this paper, we present a audio-score alignment methodology ...
  • Michos, Konstantinos; Hernández Leo, Davinia (CEUR Workshop Proceedings, 2016)
    The use of learning analytics in ICT-rich learning environments assists teachers to (re)design their learning scenarios. Teacher inquiry is a process of intentional and systematic research of teachers into their students´ ...
  • Michos, Konstantinos; Manathunga, Kalpani; Hernández Leo, Davinia (2016)
    This paper presents preliminary work aiming to identify learning analytics that can be presented to teachers or learning designers to support (re)use or (re)design of learning scenarios based on the pyramid (a.k.a. snowball) ...
  • Ath, Hasan Sercan; Bozkurt, Baris; Sentürk, Sertan (Association Dirac, 2015)
    Karar is the final tone in the Turkish makam music performances. The karar frequency, hence the concert pitch varies among performances due to the existence of many diapasons in Turkish makam music, instead of a single ...
  • Romani Picas, Oriol; Parra Rodríguez, Hèctor; Dabiri, Dara; Tokuda, Hiroshi; Hariya, Wataru; Oishi, Koji; Serra, Xavier (Audio Engineering Society, 2015)
    This paper presents a system that complements the functionality of a typical tuner by evaluating the sound quality of a music performer in real-time. It consists of a software tool that computes a score of how well single ...
  • Papiotis, Panagiotis, 1985-; Marchini, Marco, 1984-; Maestre Gómez, Esteban (12th International Conference on Music Perception and Cognition (ICMPC) - 8th Triennial Conference of the European Society, 2012)
    Musical ensembles, such as a string quartet, are a clear case of music performance where a joint interpretation of the score as well as joint action during the performance is required by the musicians. Of the several ...
  • Ivorra Cano, Antoni, 1974-; Sánchez Velázquez, Patricia; Castellví, Quim; Villanueva, Alberto; Iglesias Coma, Mar; Quesada Diez, Rita; Pañella-Vilamú, Clara; Cáceres Aguilar, Mario; Dorcaratto, Dimitri; Andaluz, Anna; Moll, Xavier; Burdío, José Miguel; Grande Posa, Luís; Burdío Pinilla, Fernando (Nature Publishing Group, 2017)
    Irreversible electroporation (IRE) has recently gained in popularity as an ablative technique, however little is known about its oncological long-term outcomes. To determine the long-time survival of animals treated with ...
  • Ivorra Cano, Antoni, 1974-; Qasrawi, Radwan Fayez Hasan; Silve, Louis Charles Arthur; Burdío Pinilla, Fernando; Abdeen, Ziad (SAGE Publications, 2017)
    Irreversible electroporation is a novel tissue ablation technique which entails delivering intense electrical pulses to target tissue, hence producing fatal defects in the cell membrane. The present study numerically ...
