Supervised descent method (SDM) applied to accurate pupil detection in off-the-shelf eye tracking systems
(ACM, 2018)
info:eu-repo/semantics/conferenceObject,
The precise detection of pupil/iris center is key to estimate gaze accurately. This fact becomes specially challenging in low cost frameworks in which the algorithms employed for high performance systems fail. In the last ...
Image feature extraction using OD-monotone functions
(Springer, 2018)
info:eu-repo/semantics/conferenceObject,
Edge detection is a basic technique used as a preliminary step
for, e.g., object extraction and recognition in image processing. Many of
the methods for edge detection can be fit in the breakdown structure by
Bezdek, ...
EEG-based endogenous online co-adaptive brain-computer interfaces: strategy for success?
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A Brain-Computer Interface (BCI) translates patterns
of brain signals such as the electroencephalogram (EEG)
into messages for communication and control. In the case of
endogenous systems the reliable detection of induced ...
T-overlap functions: a generalization of bivariate overlap functions by t-norms
(Springer, 2018)
info:eu-repo/semantics/conferenceObject,
This paper introduces a generalization of overlap functions by extending one of the boundary conditions of its definition. More specifically, instead of requiring that 'the considered function is equal to zero if and only ...
Ultra-long (275 km) random distributed feedback fiber laser for remote sensor monitoring
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
An interferometric sensor located 275 km away from the monitoring station has been interrogated by a double-pumped random distributed feedback fiber laser, reaching the longest distance in fiber optic remote sensing reported ...
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 ...
Gamma radiation measurements using an optical fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A fiber ring laser cavity configuration was used to analyze the effect of gamma-irradiation over the performance of different types of erbium doped fibers. Preliminary results validates this method to monitor gamma-radiation ...
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 ...
Optical fiber immunosensors optimized with cladding etching and ITO nanodeposition
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Etched optical fiber immunosensors, with and without ITO nanodeposition, have been developed. The performance of these immunosensors has been assessed implementing an immunoassay. The sensitivity of the mmnunosensor increased ...
Fuzzy-based energy management of a residential electro-thermal microgrid based on power forecasting
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
In this paper, an energy management strategy based on microgrid power forecasting is applied to a residential grid-connected electro-thermal microgrid with the aim of smoothing the power profile exchanged with the grid. ...
