The EMPATHIC Project: Mid-term Achievements
(ACM Digital Library, 2019-08-18)
The goal of active aging is to promote changes in the elderly community so as to maintain an active, independent and socially-engaged lifestyle. Technological advancements currently provide the necessary tools to foster ...
Bi-modal annoyance level detection from speech and text
(Sociedad Española para el Procesamiento del Lenguaje Natural, 2018-09)
The main goal of this work is the identification of emotional hints from speech. Machine learning researchers have analysed sets of acoustic parameters as potential cues for the identification of discrete emotional categories ...
Stability and Limit Oscillations of a Control Event-Based Sampling Criterion
(Hindawi Publishing Corporation, 2012)
This paper investigates the presence of limit oscillations in an adaptive sampling system. The basic sampling criterion operates in the sense that each next sampling occurs when the absolute difference of the signal amplitude ...
Suboptimal regulation of a class of bilinear interconnected systems with finite-time sliding planning horizons
(Hindawi Publishing Corporation, 2008)
This paper focuses on the suboptimization of a class of multivariable discrete-time bilinear systems consisting of interconnected bilinear subsystems with respect to a linear quadratic optimal regulation criterion which ...
Improved Determination of Q Quality Factor and Resonance Frequency in Sensors Based on the Magnetoelastic Resonance Through the Fitting to Analytical Expressions
(MDPI, 2020-10-22)
The resonance quality factor Q
is a key parameter that describes the performance of magnetoelastic sensors. Its value can be easily quantified from the width and the peak position of the resonance curve but, when the ...
Some New Generalizations of Integral Inequalities for Harmonical cr-(h1,h2)-Godunova–Levin Functions and Applications
(MDPI, 2022-12-01)
The interval analysis is famous for its ability to deal with uncertain data. This method is useful for addressing models with data that contain inaccuracies. Different concepts are used to handle data uncertainty in an ...
Controllability and Observability Results of an Implicit Type Fractional Order Delay Dynamical System
(MDPI, 2022-11-26)
Recently, several research articles have investigated the existence of solutions for dynamical systems with fractional order and their controllability. Nevertheless, very little attention has been given to the observability ...
Audio Embedding-Aware Dialogue Policy Learning
(IEEE, 2022-11-30)
Following the success of Natural Language Processing (NLP) transformers pretrained via self-supervised learning, similar models have been proposed recently for speech processing such as Wav2Vec2, HuBERT and UniSpeech-SAT. ...
Some Novel Estimates of Hermite–Hadamard and Jensen Type Inequalities for (h1,h2)-Convex Functions Pertaining to Total Order Relation
(MDPI, 2022-12-15)
There are different types of order relations that are associated with interval analysis for determining integral inequalities. The purpose of this paper is to connect the inequalities terms to total order relations, often ...
Stability and Existence of Solutions for a Tripled Problem of Fractional Hybrid Delay Differential Equations
(MDPI, 2022-12-06)
The purpose of this paper is to determine the existence of tripled fixed point results for the tripled symmetry system of fractional hybrid delay differential equations. We obtain results which support the existence of at ...
