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 ...
Stability analysis of RF power amplifiers through MIMO pole-zero identification techniques.
(2019-01-14)
El amplificador de potencia es un componente clave en la arquitectura de los transmisores de comunicaciones inhalámbricas. La complejidad de las señales de los sistemas de comunicación actuales impone unas especificaciones ...

Quantum-mechanical study of optical excitations in nanoscale systems: first-principles description of plasmons, tunneling-induced light emission and ultrastrong light-matter interaction
(2023-11-08)
This theoretical thesis applies quantum methodologies to nanophotonic systems in order to investigate the properties of optical excitations in metals, as well as the interaction of matter excitations with optical modes in ...
Space-time symmetries in classical and quantum electromagnetic scattering theory
(2023-12-01)
In this thesis we propose a novel approach to study electromagnetic wave dynamics based on thesystematic application of group theory. We show that this alternative approach leads to new insights onwell-studied topics such ...
Analysis and automatic identification of spontaneous emotions in speech from human-human and human-machine communication
(2023-09-13)
This research mainly focuses on improving our understanding of human-human and human-machineinteractions by analysing paricipants¿ emotional status. For this purpose, we have developed andenhanced Speech Emotion Recognition ...
