  • Rullo, Antonino; Serra, Edoardo; Bertino, Elisa; Lobo, Jorge (Springer, 2017)
    We present a method for computing the best provisioning of security resources for Internet of Things (IoT) scenarios characterized by a high degree of mobility. The security infrastructure is specifed by a security ...
  • Özaslan, Tan Hakan; Serra, Xavier; Arcos, Josep Lluís (Universitat Pompeu Fabra, 2012)
    Ney is an end-blown flute which is mainly used for Makam music. Although from the beginning of 20th century a score representation based on extending the Western music/nis used, because of its rich articulation repertoire, ...
  • Biglieri, Ezio; Hong, Yi; Viterbo, Emanuele (European Association for Signal Processing (EURASIP), 2008)
    Silver Code (SilC) was originally discovered in [1–4] for 2×2 multiple-input multiple-output (MIMO) transmission. It has non-vanishing minimum determinant 1/7, slightly lower than Golden code, but is fast-decodable, i.e., ...
  • Herrera Boyer, Perfecto; Bello, Juan; Widmer, Gerhard; Sandler, Mark; Celma Herrada, Òscar; Vignoli, Fabio; Pampalk, Elias; Cano, Pedro; Pauws, Steffen; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2005)
    The SIMAC project addresses the study and development of innovative components for a music information retrieval system. The key feature is the usage and exploitation of semantic descriptors of musical content that are ...
  • de Boer, Marteen; Bonada, Jordi, 1973-; Cano, Pedro; Loscos, Àlex; Serra, Xavier (International Computer Music Conference, 2000)
    This paper presents the implementation aspects of a real-time system for morphing two voices in the context of a karaoke application. It describes the software design and implementation under a PC platform and it discusses ...
  • Bonada, Jordi, 1973-; Celma Herrada, Òscar; Loscos, Àlex; Ortolà, Jaume; Serra, Xavier; Yoshioka, Yasuo; Kayama, Hiraku; Hisaminato, Yuji; Kenmochi, Hideki (International Computer Music Conference, 2001)
    This paper presents an approach to the modeling of the singing voice with a particular emphasis on the naturalness of the resulting synthetic voice. The underlying analysis/synthesis technique is based on the Spectral ...
  • Farrús, Mireia; Anguita, Jan; Anguera Miró, Xavier, 1978-; Crego, Josep Maria; de Gispert, A.; Hernando, Javier; Nadeu Camprubí, Climent (2004)
    La visió actual de la societat de la informació gira fonamentalment al voltant de la llengua escrita. No obstant, és evident que la forma més natural i espontània de comunicació entre els éssers humans és la parla, i no ...
  • Schaper, Marie-Monique; Malinverni, Laura; Parés, Narcís, 1966- (ACM Association for Computer Machinery, 2015)
    The aim of this paper is to explore techniques to design specific gestures with children to improve the interaction design of a Full- Body Interaction Learning Environment. This exploratory case study is part of the ...
  • Lluch Alvarez, Èric; Doste, Rubén; Giffard-Roisin, Sophie; This, Alexandre; Sermesant, Maxime; Camara, Oscar; De Craene, Mathieu; Morales, Hernán G. (Springer, 2017)
    Finite element methods (FEM) are generally used in cardiac 3D-electromechanical modeling. For FEM modeling, a step of a suitable mesh construction is required, which is non-trivial and time-consuming for complex geometries. ...
  • Eakin, Richard Thomas; Serra, Xavier (International Conference on Digital Audio Effects, 2009)
    We present a real-time implementation of SMS synthesis in Pure Data. This instrument focuses on interaction with the ability to continuously synthesize any frame position within an SMS sound representation, in any order, ...
  • Furelos Blanco, Daniel; Jonsson, Anders, 1973- (Association for the Advancement of Artificial Intelligence (AAAI) - Congrés ICAPS17, 2018)
    In this work we present a novel approach to solving concurrent multiagent planning problems in which several agents act in parallel. Our approach relies on a compilation from concurrent multiagent planning to classical ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    This paper aims at illustrating some applications of Finite Random Set (FRS) theory to the design and analysis of wireless communication receivers, and at pointing out similarities and differences between this scenario and ...
  • Serra, Xavier (International Computer Music Conference, 1994)
    Current sound hybridization techniques are ha.sed on the exciter-resonator model, where the spectral characteristics of a sound (resonator) are applied to another one (exciter). The tradi­ tional implementations use Linear ...
  • Janer Mestres, Jordi; Haro Berois, Martín; Roma Trepat, Gerard; Fujishima, Takuya; Kojima, Naoaki ([Sound and Music Computing], 2009)
    Sample-based music composition often involves the task of manually searching appropriate samples from existing audio. Audio mosaicing can be regarded as a way to automatize this process by specifying the desired audio ...
  • Serra, Xavier; Bonada, Jordi, 1973- (International Conference on Digital Audio Effects, 1998)
    The basic Spectral Modeling Synthesis (SMS) technique models sounds as the sum of sinusoids plus a residual. Though this analysis/synthesis system has proved to be successful in transforming sounds, more powerful and ...
  • Pacheco Estefan, Daniel; Wierenga, Sytse; Omedas, Pedro; Wilbricht , Stefan; Knoch, Habbo; Verschure, Paul F. M. J. (ACM Association for Computer Machinery, 2014)
    In this study we present a novel ICT framework for the exploration and visualization of historical information using Augmented Reality (AR) and geolocalization. The framework facilitates the geolocalization of multimedia ...
  • Oliver, Maria; Palomares, Roberto P.; Ballester, Coloma; Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    We propose a new variational method for the completion of moving shapes through binary video inpainting that works by smoothly recovering the objects into an inpainting hole. We solve it by a simple dynamic shape analysis ...
  • Farrús, Mireia; Erro, Daniel; Hernando, Javier (Universidad de Valladolid, 2008)
    Security systems relying on voice identification can be threatened by human voice imitation or synthetic voices. As voice conversion can be seen as a sort of voice imitation, this paper analyses the performance of an ...
