Characterization of the Potential Effects of EMC Filters for Power Converters on Narrowband Power Line Communications
(MDPI, 2021-01-12)
Electromagnetic Compatibility (EMC) filters are one of the main solutions for dealing with the disturbances generated by power inverters. However, they show series/parallel resonances that introduce variations in the ...
Virtual PLC Lab Enabled Physical Layer Improvement Proposals for PRIME and G3-PLC Standards
(MDPI, 2020-03-04)
Narrowband (NB) powerline communication (PLC) is extensively adopted by utilities for the communication in advanced metering infrastructure (AMI) systems. PLC technology needs to overcome channel disturbances present in ...
Refractive-Index Profile Reconstruction in Graded-Index Polymer Optical Fibers Using Raman Spectroscopy
(MDPI, 2020-05-14)
This work reports a novel method to create a 3D map of the refractive index of different graded-index polymer optical fibers (GI-POF), measuring the Raman spectra at different points of their transverse sections. Raman ...
Fabrication Quality Assessment Based on the Coupling of a Dual-Core Microstructured Polymer Optical Fiber
(MDPI, 2021-11-09)
In this paper we report on the theoretical analysis and fabrication of a dual-core microstructured polymer optical fiber (mPOF) and demonstrate how the coupling characteristics of a dual-core mPOF may be a key factor to ...
Sensitivity-optimized strongly coupled multicore fiber-based thermometer
(Elsevier, 2022-01)
[EN] In this paper, we report on a multicore fiber-based (MCF) temperature sensor that operates in a wide thermal range and that is robustly packaged to withstand harsh environments. To develop the sensor, the fundamentals ...
Multi-parameter optical gauge based on mode coupling effect in asymmetric index multi-core fibres
(Elsevier, 2022-07)
An optical gauge based on coupled multi-core fiber is proposed and experimentally demonstrated. By using direct laser writing to selectively break the fiber index profile symmetry, asymmetric mode coupling between cores ...
POF-Based Solar Concentrators Incorporating Dyes and Europium Chelates
(MDPI, 2021-05-19)
In this paper, useful models that enable time-efficient computational analyses of the performance of luminescent solar concentrators (LSCs) are developed and thoroughly described. These LSCs are based on polymer optical ...
Effects of Fabrication Methods on the Performance of Luminescent Solar Concentrators Based on Doped Polymer Optical Fibers
(MDPI, 2021-01-28)
In this work, we detail two types of fabrication processes of four polymer optical fibers doped with lumogen dyes. The fiber preforms have been manufactured with two different methods: extrusion and casting. We have compared ...
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 ...
