Gas detection using LMR-based optical fiber sensors
(MDPI, 2018)
Artículo / Artikulua,
This work presents a first approach to the utilization of Lossy Mode Resonance (LMR)
based optical fiber sensors for gas detection. The optical sensor is based on a SnO2 thin-film
fabricated onto the core of cladding ...
A highly efficient composite class-AB–AB Miller op-amp with high gain and stable from 15 pF up to very large capacitive loads
(IEEE, 2018)
Artículo / Artikulua,
In this paper, a highly power-efficient class-AB–AB Miller op-amp is discussed. The structure uses gm enhancement based on local common-mode feedback to provide class-AB operation with enhanced effective gm , open-loop ...
Labyrinth metasurface absorber for ultra-high-sensitivity terahertz thin film sensing
(Wiley, 2018)
Artículo / Artikulua,
In this work, a labyrinth metasurface sensor operating at the low‐frequency edge of the THz band is presented. Its intricate shape leads to a high electric field confinement on the surface of the structure, resulting in ...
THz sensing with anomalous extraordinary optical transmission hole arrays
(MDPI, 2018)
Artículo / Artikulua,
Subwavelength hole array (HA) metasurfaces support the so-called extraordinary optical transmission (EOT) resonance that has already been exploited for sensing. In this work, we demonstrate the superior performance of a ...
Combined dynamic programming and region-elimination technique algorithm for optimal sizing and management of lithium-ion batteries for photovoltaic plants
(Elsevier, 2018)
info:eu-repo/semantics/article,
The unpredictable nature of renewable energies is drawing attention to lithium-ion batteries. In order to make full utilization of these batteries, some research works are focused on the management of existing systems, ...
Design procedure for new compact waffle-iron ilters with transmission zeros
(IEEE, 2018)
Artículo / Artikulua,
In this paper, a novel waffle-iron filter with
transmission zeros at multiple frequencies, along with its design
procedure, is presented. The proposed filter features a high-power
behavior and a wide rejected band in a ...
On the design and performance evaluation of automatic traffic report generation systems with huge data volumes
(Wiley, 2018)
Artículo / Artikulua,
In this paper we analyze the performance issues involved in the generation of automated
traffic reports for large IT infrastructures. Such reports allow the IT manager
to proactively detect possible abnormal situations ...
Interaction between closely packed array antenna elements using meta-surface for applications such as MIMO systems and synthetic aperture radars
(Wiley, 2018)
info:eu-repo/semantics/article,
The paper presents a technique to enhance the isolation between adjacent radiating elements that is common in densely packed antenna arrays. Such antennas provide frequency beam-scanning capability needed in multiple-input ...
Antenna mutual coupling suppression over wideband using embedded periphery slot for antenna arrays
(MDPI, 2018)
info:eu-repo/semantics/article,
This paper presents a new approach to suppress interference between neighbouring radiating elements resulting from surface wave currents. The proposed technique will enable the realization of low-profile implementation of ...
Computation of traffic time series for large populations of IoT devices
(MDPI, 2018)
Artículo / Artikulua,
En este artículo se estudian las tecnicas para clasificar paquetes de tráfico de red en múltiples clases orientadas a la realización de series temporales de tráfico en escenarios de un elevado numero de clases como pueden ...
