Feasibility Assessment of a Fine-Grained Access Control Model on Resource Constrained Sensors
(MDPI, 2018-02-13)
Upcoming smart scenarios enabled by the Internet of Things (IoT) envision smart objects that provide services that can adapt to user behavior or be managed to achieve greater productivity. In such environments, smart things ...
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 ...
Expressive Policy-Based Access Control for Resource-Constrained Devices
(IEEE, 2018-02-01)
Upcoming smart scenarios enabled by the Internet of Things envision smart objects that expose services that can adapt to user behavior or be managed with the goal of achieving higher productivity, often in multi-stakeholder ...
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 ...
Crank-Nicholson method for rate equations in powder random lasers
(IOP Publishing, 2015)
In this work, we show the resolution of the rate equations in powder random lasers by using the Crank-Nicholson finite difference method. Light propagation in our powders is described by the model of light diffusion. The ...
Impact assessment of policy expressivenessof an optimised access control model forsmart sensors
(IET, 2019-05)
In the incoming internet of things (IoT) applications, smart sensors expose services to interact with them, to be parameterised, managed and maintained. Therefore, fine-grained end-to-end access control enforcement is ...
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 ...
Fuzzy and Sample Entropies as Predictors of Patient Survival Using Short Ventricular Fibrillation Recordings during out of Hospital Cardiac Arrest
(MDPI, 2018-08)
Optimal defibrillation timing guided by ventricular fibrillation (VF) waveform analysis would contribute to improved survival of out-of-hospital cardiac arrest (OHCA) patients by minimizing myocardial damage caused by ...
Application of entropy-based features to predict defibrillation outcome in cardiac arrest
(MDPI, 2016-08)
Prediction of defibrillation success is of vital importance to guide therapy and improve the survival of patients suffering out-of-hospital cardiac arrest (OHCA). Currently, the most efficient methods to predict shock ...
