Study of the Influence of Various Stress-Based Mechanisms on Polarization of an SM mPOF for the Development of Useful Devices
(IEEE, 2017-07-15)
In contrast to conventional polymer optical fibres (POFs), single-mode microstructured POFs (SM mPOF) exhibit polarization properties that make them potentially interesting for their use in the design and development of ...
Design, Fabrication and Testing of a High-Sensitive Fibre Sensor for Tip Clearance Measurements
(MDPI, 2018-08)
A highly sensitive fibre bundle-based reflective optical sensor has been designed and fabricated for Tip Clearance measurements in a turbine rig. The sensor offers high spatial and temporal resolution. The sensor probe ...
U-Shaped and Surface Functionalized Polymer Optical Fiber Probe for Glucose Detection
(MDPI, 2017-01)
In this work we show an optical fiber evanescent wave absorption probe for glucose detection in different physiological media. High selectivity is achieved by functionalizing the surface of an only-core poly(methyl ...
Assessment of the Evolution of End-Tidal Carbon Dioxide within Chest Compression Pauses to Detect Restoration of Spontaneous Circulation
(Public Library Of Science, 2021-05-18)
Background
Measurement of end-tidal CO2 (ETCO2) can help to monitor circulation during cardiopulmonary resuscitation (CPR). However, early detection of restoration of spontaneous circulation
(ROSC) during CPR using ...
Fabrication and characterization of active polymer optical fibers with a ring-doped structure
(Elsevier, 2023-01)
This paper employs the solution-doping technique for the fabrication of polymer optical fibers (POFs) doped with two perylene derivatives, Lumogen Yellow 083 and Lumogen Red 305, in different combinations. With the ...
Implementation Issues of Adaptive Energy Detection in Heterogeneous Wireless Networks
(MDPI AG, 2017-04-23)
Abstract
Spectrum sensing (SS) enables the coexistence of non-coordinated heterogeneous wireless systems operating in the same band. Due to its computational simplicity, energy detection (ED) technique has been widespread ...
Temperature effects on the emission of polymer optical fibers doped with Lumogen dyes
(Elsevier, 2022-09)
In this paper, we report the temperature effects on the luminescence of polymer optical fibers doped with Lumogen dyes (red and orange). Specifically, we have analyzed the intensity and the average wavelength of the spectra ...
Sensitivity magnification of an interferometric optical fiber sensor with a length-linked virtual reference
(Elsevier, 2023-12)
Here, it is proposed an alternative to magnify the sensitivity of a single optical fiber interferometric sensor up to two orders of magnitude. The method consists of fabricating the sensing interferometer with a specific ...
Cloud Transmission: System Performance and Application Scenarios
(IEEE, 2014)
[EN] Cloud Transmission (Cloud Txn) System is a
flexible multi-layer system that uses spectrum overlay technology
to simultaneously deliver multiple program streams with
different characteristics and robustness for ...
A new voltage probe with improved performance at the 10 kHz–500 kHz frequency range for field measurements in LV networks
(Elsevier, 2019-06-05)
[EN] Voltage measurements in the frequency range from 10 kHz to 500 kHz are used to quantify the level of the Narrow Band Power Line Communication transmitted signals, the noise and the non-intentional conducted emissions ...
