Antibacterial Activity Testing Methods for Hydrophobic Patterned Surfaces
(Nature, 2021-03-23)One strategy to decrease the incidence of hospital-acquired infections is to avoid the survival of pathogens in the environment by the development of surfaces with antimicrobial activity. To study the antibacterial behaviour ... -
Automatic Identification of Emotional Information in Spanish TV Debates and Human-Machine Interactions
De Velasco Vázquez, Mikel; Justo Blanco, Raquel ; Torres Barañano, María Inés (MDPI, 2022-02-11)
Automatic emotion detection is a very attractive field of research that can help build more natural human–machine interaction systems. However, several issues arise when real scenarios are considered, such as the tendency ... -
Can Spontaneous Emotions be Detected from Speech on TV Political Debates?
De Velasco Vázquez, Mikel; Justo Blanco, Raquel ; López Zorrilla, Asier ; Torres Barañano, María Inés (IEEE, 2019)
Decoding emotional states from multimodal signals is an increasingly active domain, within the framework of affective computing, which aims to a better understanding of Human-Human Communication as well as to improve Human- ... -
