  • Serra, Xavier; Smith, Julius O. (MIT Press, 1990)
    When generating musical sound on a digital computer, it is important to have a good model whose parameters provide a rich source of meaningf ul sound transformations. Three basic model types are used widely today far musical ...
  • Austin, Larry; Boone, Charles; Serra, Xavier (MIT Press, 1991)
    The three authors each explore an aspect of Larry Austin's 1990 extended composition for radio broadcast. Composer-writer Charles Boone examines the work for its musical and dramatic interest and for its significance as ...
  • Serra, Xavier (Palau de la Música Catalana, 1992)
    Els ordinadors han canviat les nostres vides i sabem que aixo és sols el principi de l'impacte que tindran en un futur no gaire llunyà. Intuïm que seran d'un gran ajut en feines repetitives de tot tipus i que, a la vegada, ...
  • Arcos, Josep Lluís; López de Mántaras, Ramon; Serra, Xavier (Taylor & Francis (Routledge), 1998)
    We have studied the problem of generating expressive musical performances in the context of tenor saxophone interpretations. We have done several recordings of a tenor sax playing different Jazz ballads with different ...
  • Resina, Eduard; Serra, Xavier (Associació Musica y Comunicació, 1998)
  • Herrera Boyer, Perfecto; Serra, Xavier (Ajuntament de Lleida, 1999)
  • Wright, Matthew; Beauchamp, James; Fitz, Kelly; Rodet, Xavier; Röbel, Axel; Serra, Xavier; Wakefield, Gregory (Cambridge University Press, 2000)
    We compared six sound analysis/synthesis systems used for computer music. Each system analysed the same collection of twenty-seven varied input sounds, and output the results in Sound Description Interchange Format (SDIF). ...
  • Parés, Narcís, 1966-; Parés, Roc, 1968- (MIT Press, 2001)
    Virtual reality application design is usually guided by a content-driven strategy, which gives priority to the application's content and context. In this paper, we shall describe and study a novel strategy in VR application ...
  • Farrús, Mireia; Cassan, Adán; Cervell, Sergi; Colom, Mireia; González, Ignacio; Marín, Rafael; Trotzig, David (Sociedad Española para el Procesamiento del Lenguaje Natural (SEPLN), 2001)
    Esta presentación muestra cómo funciona la Interfaz Descriptores, una aplicación que permite la sistematización de los descripores humanos en los artículos enciclopédicos del medio editorial
  • Andreu, Fuensanta; Ballester, Coloma; Caselles, Vicent; Mazón, Jose (Elsevier, 2001)
    We introduce a new concept of solution for the Dirichlet problem for the total variational flow named entropy solution. Using Kruzhkov's method of doubling variables both in space and in time we prove uniqueness and a ...
  • 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 ...
  • Andreu, Fuensanta; Caselles, Vicente; Díaz, Jesus Ildefonso; Mazón, Jose (Elsevier, 2002)
    We prove the existence of a finite extinction time for the solutions of the Dirichlet problem for the total variation flow. For the Neumann problem, we prove that the solutions reach the average of its initial datum in ...
  • Andreu, Fuensanta; Caselles, Vicente; Mazón, José (European Mathematical Society (EMS), 2002)
    We prove existence and uniqueness of solutions for the Dirichlet problem for quasilinear parabolic equations in divergent form for which the energy functional has linear growth. A typical example of energy functional we ...
  • Bellettini, Giovanni; Caselles, Vicente; Novaga, Matteo (Elsevier, 2002)
    In this paper, we study the minimizing total variation flow ut=div(Du/∣Du∣) in N for initial data u0 in Lloc1(N), proving an existence and uniqueness result. Then we characterize all bounded sets Ω of finite perimeter in ...
  • Lozano Solsona, Angel (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 ...
  • Serra, Xavier (Taylor & Francis (Routledge), 2003)
  • Ballester, Coloma; Caselles, Vicente; Monasse, Pascal (EDP Sciences, 2003)
    In [CITE], Kronrod proves that the connected components of isolevel sets of a continuous function can be endowed with a tree structure. Obviously, the connected components of upper level sets are an inclusion tree, and the ...
  • Downey, Rodney G. (Elsevier, 2003)
    The Graph k-Cut problem is that of finding a set of edges of minimum total weight, in an edge-weighted graph, such that their removal from the graph results in a graph having at least k connected components. An algorithm ...
  • Bote-Lorenzo, Miguel L.; Hernández Leo, Davinia; Dimitriadis, Yannis; Asensio-Pérez, Juan I.; Gómez-Sánchez, Eduardo; Vega-Gorgojo, Guillermo; Vaquero-Gónzalez, Luis M. (ACTA Press, 2004)
    CSCL applications are complex distributed systems that pose/nspecial requirements towards achieving success in educational/nsettings. Flexible and efficient design of collaborative activities/nby educators is a key ...
  • Zheng, Haitao; Lozano Solsona, Angel; Haleem, Mohamed (Hindawi, 2004)
    We propose a new automatic repeat request (ARQ) scheme for MIMO systems with multiple transmit and receive antennas. The substreams emitted from various transmit antennas encounter distinct propagation channels and thus ...
