Contribution to the development of optical fibre sensors based on microstructured optical fibres to detect gases and volatile organic compounds
(2019)
info:eu-repo/semantics/doctoralThesis,
Desde la primera publicación relacionada con las fibras micro estructuradas (MOFs), el desarrollo de sensores basados en fibra óptica (OFSs), que utilizan este tipo de fibras, se ha visto incrementado atrayendo el interés ...
Far-field and near-field physics of extraordinary THz transmitting hole-array antennas
(IEEE, 2019)
Artículo / Artikulua,
Despite three decades of effort, predicting accurately
extraordinary transmission through subwavelength hole
arrays has proven challenging. The lack of quantitative design
and modeling capability to take into account ...
A water content continuous monitoring of grapevine xylem tissue using a portable low-power cost-effective FMCW radar
(IEEE, 2019)
Artículo / Artikulua,
This paper presents the real-time monitoring of a grapevine’s water content that flows up through the xylem tissue by means of a frequency-modulated continuous-wave (FMCW) radar. The application of an optimization process, ...
Robust and accurate 2D-tracking-based 3D positioning method: application to head pose estimation
(Elsevier, 2019)
info:eu-repo/semantics/article,
Head pose estimation (HPE) is currently a growing research field, mainly because of the proliferation of human–computer interfaces (HCI) in the last decade. It offers a wide variety of applications, including human behavior ...
Compensation of nonlocal effects induced by the extinction ratio of pump pulses in Brillouin optical time-domain analysis sensors
(Optical Society of America, 2019)
Artículo / Artikulua,
We demonstrate a technique to compensate the nonlocal effects that appear in Brillouin optical time-domain analysis sensors when pump pulses with limited extinction ratio are deployed. These recently discovered nonlocal ...
FDTD and empirical exploration of human body and UWB radiation interaction on TOF ranging
(IEEE, 2019)
Artículo / Artikulua,
In time-of-flight (TOF)-based human ranging systems, target sensors are often mounted on or close to the human
body, which may raise non-line-of-sight (NLOS) cases and lead
to significant ranging errors depending on the ...
Lossy mode resonance optical sensors based on indium-gallium-zinc oxide thin film
(Elsevier, 2019)
Artículo / Artikulua,
This work discusses an application of electrically conductive and optically transparent indium-gallium-zinc oxide (IGZO) thin films for fabrication of lossy mode resonance (LMR) based optical fiber refractometers. The films ...
Spatial characterization of personal RF-EMF exposure in public transportation buses
(IEEE, 2019)
Artículo / Artikulua,
New services and applications within vehicular environments employ multiple wireless communication systems,
within a Heterogeneous Network framework. In this context, evaluation of electromagnetic field impact is compulsory, ...
Control of a photovoltaic array interfacing current-mode-controlled boost converter based on virtual impedance emulation
(IEEE, 2019)
info:eu-repo/semantics/article,
Due to the nonlinear characteristics of a photovoltaic (PV) array, its regulation is highly dependent on the operating point. Focusing on a dc-dc boost converter, this paper first shows how the PV voltage and inductor ...
Modeling ground-shielded integrated inductors incorporating frequency-dependent effects and considering multiple resonances
(IEEE, 2019)
Artículo / Artikulua,
A model for integrated spiral inductors which incorporates the physically expected frequency-dependent effects modifying the device's impedance is proposed. Moreover, it is demonstrated that the effect of resonances occurring ...
