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 ...
Integration of autonomous wireless sensor networks in academic school gardens
(MDPI, 2018)
info:eu-repo/semantics/article,
In this work, the combination of capabilities provided by Wireless Sensor Networks (WSN) with parameter observation in a school garden is employed in order to provide an environment for school garden integration as a ...
An efficient numerical method for singularly perturbed time dependent parabolic 2D convection-diffusion systems
(Elsevier, 2018)
info:eu-repo/semantics/article,
In this paper we deal with solving efficiently 2D linear parabolic singularly perturbed systems of convection–diffusion type. We analyze only the case of a system of two equations where both of them feature the same diffusion ...
Comparison between different structures of suspended-core microstructured optical fibers for volatiles sensing
(MDPI, 2018)
info:eu-repo/semantics/article,
In this paper, different core structures of microstructured optical fibers (MOFs) for low-finesse Fabry-Perot (FP) sensors are experimentally compared to get the highest sensitivity. These devices are designed for volatile ...
Virtual FBGs using saturable absorbers for sensing with fiber lasers
(MDPI, 2018)
info:eu-repo/semantics/article,
The spectral narrowing of Fiber Bragg Gratings (FBGs) introduced by unpumped Er-doped fiber (EDF) was analyzed for fiber lasers (FL). Owing to spatial hole burning (SHB), the spectral response of a virtual FBG can be ...
Strong angular dependence of resonant states in 2D dielectric cylinder rings
(AIP Publishing, 2018)
info:eu-repo/semantics/article,
We investigate collective resonators made of dielectric cylinders assembled as two-dimensional regular octagons and decagons. These structures exhibit collective resonance states that change their intensity with the incident ...
SnO2-MOF-Fabry-Perot optical sensor for relative humidity measurements
(Elsevier, 2018)
Artículo / Artikulua,
In this paper, a new optical fiber sensor for relative humidity measurements is presented and characterized. The sensor is
based on a SnO2 sputtering deposition on a microstructured optical fiber (MOF) low-finesse Fabry-Pérot ...
Managing transportation externalities in the Pyrenees region: measuring the willingness-to-pay for road freight noise reduction using an experimental auction mechanism
(Elsevier, 2018)
info:eu-repo/semantics/article,
The estimation of the noise impact caused by road freight transportation is critical to have acknowledgment of the ambiance pollution caused by road traffic crossing geographical areas containing important natural resources. ...
Real-time imaging with frequency scanning array antenna for industrial inspection applications at W band
(Springer, 2018)
info:eu-repo/semantics/article,
A real-time imaging system based on a frequency scanning antenna for conveyor belt setups is presented in this paper. The frequency scanning antenna together with an inexpensive parabolic reflector operates at the W band ...
Quantum antenna arrays: the role of quantum interference on direction-dependent photon statistics
(American Physical Society, 2018)
info:eu-repo/semantics/article,
We investigate the role of quantum interference phenomena on the characteristics of the fields radiated by an array of quantum emitters. In analogy to, but distinct from, classical outcomes, we demonstrate that the array ...
