    Article
    Open Access
    Conditional Restricted Boltzmann Machine (CRBM) is a promising candidate for a multidimensional system modeling that can learn a probability distribution over a set of data. It is a specific type of an artificial neural ...

  • Efficiency analysis of modern vector architectures: vector ALU sizes, core counts and clock frequencies 

    Barredo Ferreira, Adrián; Cebrián González, Juan Manuel; Valero Cortés, Mateo; Casas Guix, Marc; Moreto Planas, Miquel (2020-03)
    Article
    Open Access
    Moore’s Law predicted that the number of transistors on a chip would double approximately every 2 years. However, this trend is arriving at an impasse. Optimizing the usage of the available transistors within the thermal ...

  • Essentiality of managing the resource information in the coordinated fog-to-cloud paradigm 

    Sengupta, Souvik; García Almiñana, Jordi; Masip Bruin, Xavier (2019-12-26)
    Article
    Restricted access - publisher's policy
    Fog-to-cloud (F2C) computing is an emerging computational platform. By combing the cloud, fog, and IoT, it provides an excellent framework for managing and coordinating the resources in any smart computing domain. Efficient ...

    Article
    Restricted access - publisher's policy
    Measurement-Based Probabilistic Timing Analysis (MBPTA) facilitates the analysis of complex software running on hardware comprising high-performance features. MBPTA also aims at preventing additional analysis costs for ...

  • Reversible fingerprinting for genomic information 

    Naro, Daniel; Delgado Mercè, Jaime; Llorente Viejo, Silvia (2020-01-03)
    Article
    Restricted access - publisher's policy
    New genome sequencing technologies have simplified the generation of genomic data, making them more common but in turn a likely target of attack. Security strategies have been devised such as restricting the amount of ...

  • A comparative study of calibration methods for low-cost ozone sensors in IoT platforms 

    Ferrer Cid, Pau; Barceló Ordinas, José María; García Vidal, Jorge; Ripoll, Anna; Viana, Mar (2019-12-01)
    Article
    Open Access
    This paper shows the result of the calibration process of an Internet of Things platform for the measurement of tropospheric ozone (O 3 ). This platform, formed by 60 nodes, deployed in Italy, Spain, and Austria, consisted ...

  • A GRASP meta-heuristic for evaluating the latency and lifetime impact of critical nodes in large wireless sensor networks 

    Sembroiz Ausejo, David; Ojaghi Kahjogh, Behnam; Careglio, Davide; Ricciardi, Sergio (Multidisciplinary Digital Publishing Institute, 2019-11-01)
    Article
    Open Access
    Wireless Sensor Networks (WSN) have lately been gaining momentum thanks to the hardware improvements and standardization software efforts. Moreover, the appearance of Internet of Things (IoT) and its reliance on sensors ...

  • CGPA: Coarse-Grained Pruning of Activations for Energy-Efficient RNN Inference 

    Riera Villanueva, Marc; Arnau Montañés, José María; González Colás, Antonio María (2019-09-01)
    Article
    Open Access
    Recurrent neural networks (RNNs) perform element-wise multiplications across the activations of gates. We show that a significant percentage of activations are saturated and propose coarse-grained pruning of activations ...

  • Adding security and privacy to genomic information representation 

    Delgado Mercè, Jaime; Llorente Viejo, Silvia; Naro, Daniel (2019)
    Article
    Open Access
    Provision of security and privacy to genomic data is a key issue in current genomic information representation. Existing formats do not give a solution to these issues (or they provide a partial one), so new solutions are ...

  • A survey on mobility-induced service migration in the fog, edge, and related computing paradigms 

    Rejiba, Zeineb; Masip Bruin, Xavier; Marín Tordera, Eva (2019-09-01)
