  The paper presents two mechanisms for designing an on-demand, reliable and efficient collection protocol for Wireless Sensor Networks. The former is the Bidirectional Link Quality Estimation, which allows nodes to easily ...
• The Use of interval ratios in consonance perception by rats (Rattus norvegicus) and humans (Homo sapiens)

  Crespo Bojorque, Paola, 1985-; Toro Soto, Juan Manuel, 1976- (American Psychological Association (APA), 2016)

  Traditionally, physical features in musical chords have been proposed to be at the root of consonance perception. Alternatively, recent studies suggest that different types of experience modulate some perceptual foundations ...
• A variational model for P+XS image fusion

  Ballester, Coloma; Caselles, Vicente; Igual, Laura; Verdera, Joan; Rougé, Bernard (Springer, 2006)

  We propose an algorithm to increase the resolution of multispectral satellite images knowing the panchromatic image at high resolution and the spectral channels at lower resolution. Our algorithm is based on the assumption ...
• Level lines selection with variational models for segmentation and encoding

  Ballester, Coloma; Caselles, Vicente; Igual, Laura; Garrido, Luís (Springer, 2007)

  This paper discusses the interest of the Tree of Shapes of an image as a region oriented image representation. The Tree of Shapes offers a compact and structured representation of the family of level lines of an image. ...
• Effects of encouraging the use of gestures on speech

  Cravotta, Alice; Busà, Maria Grazia; Prieto Vives, Pilar, 1965- (American Speech-Language-Hearing Association, 2019)

  Purpose: Previous studies have investigated the effects of the inability to produce hand gestures on speakers' prosodic features of speech; however, the potential effects of encouraging speakers to gesture have received ...
• Multi-feature beat tracking

  Zapata González, José Ricardo; Davies, Matthew E. P.; Gómez Gutiérrez, Emilia, 1975- (Institute of Electrical and Electronics Engineers (IEEE), 2014)

  A recent trend in the field of beat tracking for musical audio signals has been to explore techniques for measuring the level of agreement and disagreement between a committee of beat tracking algorithms. By using beat ...
• On politics and pandemic: how do Chilean media talk about disinformation and fake news in their social networks?

  Cárcamo Ulloa, Luis; Cárdenas Neira, Camila; Scheihing-García, Eliana; Sáez-Trumper, Diego; Vernier, Matthieu; Blaña-Romero, Carlos (MDPI, 2023)

  Citizens get informed, on a daily basis, from social networks in general and from the media in particular. Accordingly, the media are increasingly expressing their concern about phenomena related to disinformation. This ...
• PALANTIR: an NFV-based security-as-a-service approach for automating threat mitigation

  Compastié, Maxime; López Martínez, Antonio; Fernández, Carolina; Gil Pérez, Manuel; Tsarsitalidis, Stylianos; Xylouris, George; Mlakar, Izidor; Kourtis, Michail Alexandros; Šafran, Valentino (MDPI, 2023)

• How to handle health-related small imbalanced data in machine learning?

  Rauschenberger, Maria; Baeza Yates, Ricardo (De Gruyter, 2020)

  When discussing interpretable machine learning results, researchers need to compare them and check for reliability, especially for health-related data. The reason is the negative impact of wrong results on a person, such ...
• The creative drummer: an eeg-based pilot study on the correlates of emotions and creative drum playing

  Ramírez, Rafael,1966-; Reija, Xavier (MDPI, 2023)
