Smart Grid Applications for a Practical Implementation of IP over Narrowband Power Line Communications
(MDPI, 2017-11-06)
Abstract
Currently, Advanced Metering Infrastructure (AMI) systems have equipped the low voltage section with a communication system that is being used mainly for metering purposes, but it can be further employed for ...
Photonic Low Cost Micro-Sensor for in-Line Wear Particle Detection in Flowing Lube Oils
(MDPI, 2017-03)
The presence of microscopic particles in suspension in industrial fluids is often an early warning of latent or imminent failures in the equipment or processes where they are being used. This manuscript describes work ...
Optical Tip Clearance Measurements as a Tool for Rotating Disk Characterization
(MDPI, 2017-01)
An experimental investigation on the vibrational behavior of a rotating disk by means of three optical fiber sensors is presented. The disk, which is a scale model of the real disk of an aircraft engine, was assembled in ...
An Architecture for On-Line Measurement of the Tip Clearance and Time of Arrival of a Bladed Disk of an Aircraft Engine
(MDPI, 2017-10)
Safety and performance of the turbo-engine in an aircraft is directly affected by the health of its blades. In recent years, several improvements to the sensors have taken place to monitor the blades in a non-intrusive ...
A Survey on the Contributions of Software-Defined Networking to Traffic Engineering
(IEEE, 2017-05-31)
Since the appearance of OpenFlow back in 2008, software-defined networking (SDN) has gained momentum. Although there are some discrepancies between the standards developing organizations working with SDN about what SDN is ...
A Robust Optimization Based Energy-Aware Virtual Network Function Placement Proposal for Small Cell 5G Networks with Mobile Edge Computing Capabilities
(Hindawi, 2017)
In the context of cloud-enabled 5G radio access networks with network function virtualization capabilities, we focus on the virtual network function placement problem for a multitenant cluster of small cells that provide ...
QoE-Oriented Mobile Edge Service Management Leveraging SDN and NFV
(Hindawi, 2017)
5G envisages a "hyperconnected society" where trillions of diverse entities could communicate with each other anywhere and at any time, some of which will demand extremely challenging performance requirements such as ...
Fabrication and Characterization of Polymer Optical Fibers Doped with Perylene-Derivatives for Fluorescent Lighting Applications
(MDPI, 2017-08)
Four different dye-doped polymer optical fibers (POFs) have been fabricated following a two-step fabrication process of preform extrusion and fiber drawing, using poly-(methyl methacrylate) (PMMA) as host material and dye ...
Characterization of Chromatic Dispersion and Refractive Index of Polymer Optical Fibers
(MDPI, 2017-12-20)
The chromatic dispersion and the refractive index of poly(methyl methacrylate) polymer optical fibers (POFs) have been characterized in this work by using a tunable femtosecond laser and a Streak Camera. The characterization ...
Optical Characterization of Doped Thermoplastic and Thermosetting Polymer-Optical-Fibers
(MDPI, 2017-03)
The emission properties of a graded-index thermoplastic polymer optical fiber and a step-index thermosetting one, both doped with rhodamine 6G, have been studied. The work includes a detailed analysis of the amplified ...
