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 ...
Emotion Detection from Speech and Text
(International Speech Communication Association, 2018-11-21)
The main goal of this work is to carry out automatic emo-tion detection from speech by using both acoustic and textualinformation. For doing that a set of audios were extracted froma TV show were different guests discuss ...
Iruzurrezko portaeren detekzioa crowd motako etiketazioan
(Udako Euskal Unibertsitatea, 2019-05)
This work aims at detecting low quality labels in crowdsourcing annotation tasks. We validate our proposal carrying out experiments in a difficult and subjective task: emotion recognition. We have developed several measures ...

Lan honetan sare neuronalen bidez euskaraz hitz egiten ikasten duen elkarrizketa sistema automatikoa aurkezten dugu. Horretarako, Turingen testaren ideia era konputazionalean inplementatzen duten sare neuronal sortzaile ...
A Novel Micro- and Nano-Scale Positioning Sensor Based on Radio Frequency Resonant Cavities
(MDPI, 2014-06)
In many micro- and nano-scale technological applications high sensitivity displacement sensors are needed, especially in ultraprecision metrology and manufacturing. In this work a new way of sensing displacement based on ...
Interface electronics for an RF resonance-based displacement sensor
(IOP Publishing LTD, 2013)
We propose, design, and test an electronic interface for a new standalone, affordable and compact displacement transducer based on resonant cavities. The operation of the interface establishes a self-resonance in the ...
Aportaciones teóricas y prácticas a las tecnologías del habla: Sautrela, un entorno de desarrollo
(2016-01-22)
Las Tecnologías del Habla (TH) abarcan un amplio conjunto de áreas de investigación. Sin embargo, gran parte de estas disciplinas carece de las herramientas software que permitan implementar de una manera sencilla nuevas ...
Experimental characterization and control of stability margins in microwave amplifiers.
(2016-09-29)
Robust design of microwave amplifiers implies the lack of undesired autonomous frequency components for operating conditions that can be very far from nominal. However, microwave amplifiers are prone to exhibit spurious ...
