State of the Art and Trends Review of Smart Metering in Electricity Grids
(MDPI, 2016-03)
Climate change, awareness of energy efficiency, new trends in electricity markets, the obsolescence of the actual electricity model, and the gradual conversion of consumers to prosumer profiles are the main agents of ...
A comprehensive review of the impact of transmission technologies on the electrical grid
(Imprenta Universidad de Antioquia, 2019-05-17)
The electrical infrastructure needs the integration of communication technologies, and in recent decades the progress has been significant. Therefore, this work presents the latest advances in this subject, as well as new ...
Aspects of quality control of wind profiler measurements in complex topography
(Copernicus Gesellschaft, 2014)
It is well known in the scientific community that some remote sensing instruments assume that sample volumes present homogeneous conditions within a defined meteorological profile. At complex topographic sites and under ...
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 ...
Harnessing Deep-Hole Drilling to Fabricate Air-Structured Polymer Optical Fibres
(MDPI, 2019-10-24)
The performance of a precisely controlled drilling technique is critical in the fabrication process of microstructured polymer optical fibres. For the creation of a holey preform, adequate drilling bits with large ...
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 ...
