Power-efficient current-mode analog circuits for highly integrated ultra low power wireless transceivers
(2014)
Tesis doctoral / Doktoretza tesia,
In this thesis, current-mode low-voltage and low-power techniques have been applied to implement novel analog circuits for zero-IF receiver backend design, focusing on amplification, filtering and detection stages. The ...
Dosimetric study of the radiolectric influence of humans into complex environments through determistic simulations and the implementation of a simplified model
(2014)
Tesis doctoral / Doktoretza tesia,
The research presented in this thesis falls under the framework of dosimetry and deterministic estimations. A dosimetric study is carried out with the aid of a 3D Ray Launching simulation technique, by means of an in-house ...
Optical fiber sensors based on nanostructured materials for environmental applications
(2014)
Tesis doctoral / Doktoretza tesia,
La contaminación ambiental es la presencia de agentes físicos, químicos o biológicos presentes en el agua, suelo y aire; siendo perjudiciales para la salud de las personas, así como para la vida vegetal y animal. Las ...
Contribution to the development of functional nanostructured coatings based on silver nanoparticles
(2014)
Tesis doctoral / Doktoretza tesia,
Esta tesis se centra en la síntesis de nanopartículas de plata (AgNPs) y su posterior incorporación en recubrimientos delgados usando dos métodos alternativos: el proceso de síntesis in situ (ISS) de AgNPs y la técnica de ...
The potential integration of distributed generation in medium & low voltage grids: the applicability of power flow and hardware-in-the-loop tools for simulation and validation
(2014)
Tesis doctoral / Doktoretza tesia,
The current thesis is dedicated to the penetration of DG technology into a MV/LV distribution
network that may loosely represent an Island or autonomous power system since MV/LV levels are
of high interest as most of ...
New developments in the THz field for imaging applications
(2014)
