High sensitivity fiber-optic liquid level sensor using biconical tapered fibers
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A liquid level sensor is presented using a biconical tapered standard single-mode fiber, being its main characteristic an outstanding sensitivity for a low cost transducer. Temperature compensation is enabled with the same ...
Microstructured optical fiber sensor for soil moisture measurements
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A discrete sensor based on a Sn0₂-FP (Fabry-Pérot) cavity is presented and characterized in real soil conditions. Results are compared, for the first time to our knowledge, with a commercial capacitive sensor and gravimetric ...
Cloud tomography applied to sky images: a virtual testbed
(Elsevier, 2018)
info:eu-repo/semantics/article,
Two tomographic techniques are applied to two simulated sets of sky images with different cloud fraction. The Algebraic Reconstruction Technique (ART) is applied to optical depth maps from sky images to reconstruct 3-D ...

Techno-economic assessment of high renewable energy source penetration in the Bolivian interconnected electric system
(University of Minho, 2018)
info:eu-repo/semantics/conferenceObject,
To reduce GHG emissions to reach the 2°C level, the International Energy Agency, projected that electricity generation based in renewable source should increase from 3% today to more than 20% by 2040 [1]. This transition ...
Real time measuring system of multiple chemical parameters using microstructured optical fibers based sensors
(IEEE, 2018)
info:eu-repo/semantics/article,
In this paper, a multiplexing system for simultaneous interrogation of optical fiber sensors which measure different parameters is presented and validated. The whole system has been tested with 6 different sensing heads ...
Watt-level green random laser at 532 nm by SHG of Yb-doped fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/article,
We have developed a Watt-level random laser at 532 nm. The laser is based on a 1064 nm random distributed ytterbium-gain assisted fiber laser seed with a 0.35 nm line-width and 900 mW polarized output power. A study for ...
Introducing I2Head database
(ACM (Association for Computing Machinery), 2018)
info:eu-repo/semantics/conferenceObject,
I2Head database has been created with the aim to become an optimal reference for low cost gaze estimation. It exhibits the following outstanding characteristics: it takes into account key aspects of low resolution eye ...
On the on-site measurement of the degradation rate of crystalline silicon PV modules at plant level
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
This paper proposes a method for measuring the degradation rate of crystalline silicon PV modules at plant level in two different ways as a form of verification. As actual levels of degradation rate have been observed to ...
