    Article
    Open Access
    In the last decade, technological advances led to the launch of two satellite missions dedicated to measure the Earth’s surface soil moisture (SSM): the ESA’s Soil Moisture and Ocean Salinity (SMOS) launched in 2009, and ...
  • Machine learning-based in-band OSNR estimation from optical spectra 

    Locatelli, Fabiano; Christodoulopoulos, Konstantinos; Svaluto Moreolo, Michela; Fàbrega, Josep Maria; Spadaro, Salvatore (2019-12-15)
    Article
    Open Access
    Measuring the optical signal to noise ratio (OSNR) at certain network points is essential for failure handling, for single connection but also global network optimization. Estimating OSNR is inherently difficult in dense ...
  • Time-domain speech enhancement using generative adversarial networks 

    Pascual de la Puente, Santiago; Serra, Joan; Bonafonte Cávez, Antonio (2019-11-01)
    Article

    Speech enhancement improves recorded voice utterances to eliminate noise that might be impeding their intelligibility or compromising their quality. Typical speech enhancement systems are based on regression approaches ...
  • A review of RFI mitigation techniques in microwave radiometry 

    Querol, Jorge; Pérez Portero, Adrián; Camps Carmona, Adriano José (Multidisciplinary Digital Publishing Institute (MDPI), 2019-12-17)
    Article
    Open Access
    Radio frequency interference (RFI) is a well-known problem in microwave radiometry (MWR). Any undesired signal overlapping the MWR protected frequency bands introduces a bias in the measurements, which can corrupt the ...
  • Exploring efficient neural architectures for linguistic-acoustic mapping in text-to-speech 

    Pascual de la Puente, Santiago; Serra, Joan; Bonafonte Cávez, Antonio (Multidisciplinary Digital Publishing Institute, 2019-08-17)
    Article
    Open Access
    Conversion from text to speech relies on the accurate mapping from linguistic to acoustic symbol sequences, for which current practice employs recurrent statistical models such as recurrent neural networks. Despite the ...
  • Energy sharing and trading in multi-operator heterogeneous network deployments 

    Oikonomakou, Maria; Antonopoulos, Angelos; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (Institute of Electrical and Electronics Engineers (IEEE), 2019-05-01)
    Article
    Open Access
    With a view to the expected increased data traffic volume and energy consumption of the fifth generation networks, the use of renewable energy (RE) sources and infrastructure sharing have been embraced as energy and ...
  • Analysis of pre- and post-mine closure surface deformations in western xuzhou coalfield from 2006 to 2018 

    Zheng, Meinan; Zhang, Hongzhen; Deng, Kazhong; Du, Sen; Wang, Liuyu (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
    Article
    Open Access
    Economic development and population expansion in mining cities have led to a growing scarcity of land for construction and thus the closed mines land reuse is extremely urgent. Exploration of the law of surface deformation ...
  • Restricted Boltzmann machine vectors for speaker clustering and tracking tasks in TV broadcast shows 

    Khan, Umair; Safari, Pooyan; Hernando Pericás, Francisco Javier (Multidisciplinary Digital Publishing Institute, 2019-07-09)
    Article
    Open Access
    Restricted Boltzmann Machines (RBMs) have shown success in both the front-end and backend of speaker verification systems. In this paper, we propose applying RBMs to the front-end for the tasks of speaker clustering and ...
  • Two-dimensional mineral dust radiative effect calculations from CALIPSO observations over Europe 

    Granados Muñoz, María José; Sicard, Michaël; Papagiannopoulos, Nikolaos; Barragán Cuesta, Rubén; Bravo Aranda, Juan Antonio; Nicolae, D. (European Geosciences Union (EGU), 2019-10-24)
    Article
    Open Access
    A demonstration study to examine the feasibility of retrieving dust radiative effects based on combined satellite data from MODIS (Moderate Resolution Imaging Spectroradiometer), CERES (Clouds and the Earth's Radiant Energy ...
