A Multi-Site NFV Testbed for Experimentation With SUAV-Based 5G Vertical Services
(Institute of Electrical and Electronics Engineers, 2020-06-26)
[EN] With the advent of 5G technologies, vertical markets have been placed at the forefront,
as fundamental drivers and adopters of technical developments and new business models. Small Unmanned
Aerial Vehicles (SUAVs) ...
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 ...
Selective ultrasensitive optical fiber nanosensors based on plasmon resonance energy transfer
(American Chemical Society, 2020-04-03)
The facet of optical fibers coated with nanostructures enable the development of ultraminiature and sensitive (bio)chemical sensors. The reported sensors until now lack of specificity and the fabrication methods offer poor ...
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 ...
Highly Sensitive Multicore Fiber Accelerometer for Low Frequency Vibration Sensing
(Nature, 2020-09-30)
We report on a compact, highly sensitive all-fiber accelerometer suitable for low frequency and low amplitude vibration sensing. The sensing elements in the device are two short segments of strongly coupled asymmetric ...
Composed multicore fiber structure for direction-sensitive curvature monitoring
(2020-07-01)
The present work deals with a curvature sensor that consists of two segments of asymmetric multicore fiber (MCF) fusion spliced with standard single mode fiber (SMF). The MCF comprises three strongly coupled cores; one of ...
Continuous Quantitative Risk Management in Smart Grids Using Attack Defense Trees
(MDPI, 2020-08-07)
Although the risk assessment discipline has been studied from long ago as a means to support security investment decision-making, no holistic approach exists to continuously and quantitatively analyze cyber risks in scenarios ...
Towards the Prediction of Rearrest during Out-of-Hospital Cardiac Arrest
(MDPI, 2020-07-09)
A secondary arrest is frequent in patients that recover spontaneous circulation after an out-of-hospital cardiac arrest (OHCA). Rearrest events are associated to worse patient outcomes, but little is known on the heart ...
High-performance vector bending and orientation distinguishing curvature sensor based on asymmetric coupled multi-core fibre
(Nature, 2020-08-20)
Fibre optic technology is rapidly evolving, driven mainly by telecommunication and sensing applications. Excellent reliability of the manufacturing processes and low cost have drawn ever increasing attention to fibre-based ...
Modeling the impact of ventilations on the capnogram in out-of-hospital cardiac arrest
(Public Library Science, 2020-02-05)
Aim
Current resuscitation guidelines recommend waveform capnography as an indirect indicator of perfusion during cardiopulmonary resuscitation (CPR). Chest compressions (CCs) and ventilations during CPR have opposing ...
