  • Reduction of pulse distortion in travelling wave semiconductor optical amplifiers 

    Soneira Ferrando, M. José; Ruiz Moreno, Sergio (1991)
    Conference report
    Open Access
    The possibility of reducing the gain saturation during the pulse amplification process by means of the compensation of the carrier density variations is investigated. This should be useful in many optical systems and, ...
  • Design of a laser source using a travelling wave optical amplifier with external feedback 

    Ruiz Moreno, Sergio; Soneira Ferrando, M. José (1991)
    Conference report
    Open Access
    An analysis is made of the performance of an optical source which was designed beginning with the external feedback of a traveling wave optical amplifier (TWOA). The proposed structure is analyzed using a computer model ...
  • Increasing multicore system efficiency through intelligent bandwidth shifting 

    Jiménez, Víctor; Buyuktosunoglu, Alper; Bose, Pradip; O'Connell, Francis P.; Cazorla Almeida, Francisco Javier; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report

    Memory bandwidth is a crucial resource in computing systems. Current CMP/SMT processors have a significant number of cores and they can run many threads concurrently. This large thread count adds high pressure to the memory ...
  • Coherence protocol for transparent management of scratchpad memories in shared memory manycore architectures 

    Álvarez, Lluc; Vilanova, Lluís; Moreto Planas, Miquel; Casas, Marc; González Tallada, Marc; Martorell Bofill, Xavier; Navarro, Nacho; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Association for Computing Machinery (ACM), 2015)
    Conference report
    Open Access
    The increasing number of cores in manycore architectures causes important power and scalability problems in the memory subsystem. One solution is to introduce scratchpad memories alongside the cache hierarchy, forming a ...
  • Diseño del módulo emisor-receptor para un prototipo clínico de tomógrafo de microondas 

    Torres Viñals, Jordi; Broquetas Ibars, Antoni; Jofre Roca, Lluís (1991)
    Conference report
    Open Access
    This paper presents the design of an emitter-receiver system for a clinical microwave tomographic scanner prototype. A new design has been considered to reduce the problems of a prior experimental prototype in the department, ...

    Huge amount of algorithmic research is being done in the field of optical networks, including Routing and Spectrum Allocation (RSA), elastic operations, spectrum defragmentation, and other re-optimization algorithms. ...
  • Evaluating link prediction on large graphs 

    Garcia Gasulla, Dario; Cortés García, Claudio Ulises; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (IOS Press, 2015)
    Conference report
    Open Access
    Exploiting network data (i.e., graphs) is a rather particular case of data mining. The size and relevance of network domains justifies research on graph mining, but also brings forth severe complications. Computational ...
  • ALOJA-ML: a framework for automating characterization and knowledge discovery in Hadoop deployments 

    Berral García, Josep Lluís; Poggi, Nicolas; Carrera Pérez, David; Call, Aaaron; Reinauer, Rob; Green, Daron (Association for Computing Machinery (ACM), 2015)
    Conference report
    Open Access
    This article presents ALOJA-Machine Learning (ALOJA-ML) an extension to the ALOJA project that uses machine learning techniques to interpret Hadoop benchmark performance data and performance tuning; here we detail the ...
