Dynamic Licensed Shared Access - a New Architecture and Spectrum Allocation Techniques
This paper proposes a new system architecture for Licensed Shared Access (LSA) wireless networks, as well as novel band management techniques for fair and ranking-based spectrum allocation. The proposed architecture builds upon recently standardized and regulatory-accepted LSA systems and stems from the work done in the EU-funded project ADEL. Two new resource allocation algorithms are introduced and their behaviour is validated via system-level simulations
Water safety in healthcare facilities. The Vieste Charter
The Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health (GISIO-SItI) and the Local Health Authority of Foggia, Apulia, Italy, after the National Convention "Safe water in healthcare facilities" held in Vieste-Pugnochiuso on 27-28 May 2016, present the "Vieste Charter", drawn up in collaboration with experts from the National Institute of Health and the Ministry of Health. This paper considers the risk factors that may affect the water safety in healthcare facilities and reports the current regulatory frameworks governing the management of installations and the quality of the water. The Authors promote a careful analysis of the risks that characterize the health facilities, for the control of which specific actions are recommended in various areas, including water safety plans; approval of treatments; healthcare facilities responsibility, installation and maintenance of facilities; multidisciplinary approach; education and research; regional and national coordination; communication
Optimizing C-RAN Backhaul Topologies: A Resilience-Oriented Approach Using Graph Invariants
ABSTRACT: At the verge of the launch of the first commercial fifth generation (5G) system, trends in wireless and optical networks are proceeding toward increasingly dense deployments, supporting resilient interconnection for applications that carry higher and higher capacity and tighter latency requirements. These developments put increasing pressure on network backhaul and drive the need for a re-examination of traditional backhaul topologies. Challenges of impending networks cannot be tackled by star and ring approaches due to their lack of intrinsic survivability and resilience properties, respectively. In support of this re-examination, we propose a backhaul topology design method that formulates the topology optimization as a graph optimization problem by capturing both the objective and constraints of optimization in graph invariants. Our graph theoretic approach leverages well studied mathematical techniques to provide a more systematic alternative to traditional approaches to backhaul design. Specifically, herein, we optimize over some known graph invariants, such as maximum node degree, topology diameter, average distance, and edge betweenness, as well as over a new invariant called node Wiener impact, to achieve baseline backhaul topologies that match the needs for resilient future wireless and optical networks
CARTA DI VIESTE: SICUREZZA DELLâACQUA NELLE STRUTTURE SANITARIE
Il Gruppo Italiano Studio Igiene Ospedaliera della SItI e il Dipartimento di Prevenzione ASL
FG, a conclusione del Convegno Nazionale âAcque sicure nelle strutture sanitarieâ svoltosi
a PugnochiusoâVieste il 27-28 maggio 2016, in collaborazione con gli esperti dellâIstituto
Superiore di SanitĂ e del Ministero della Salute, presentano la âCarta di Viesteâ. Tale
documento, di natura programmatica, intende supportare una cultura di prevenzione e
controllo dei rischi associati ad ogni utilizzo idrico nella pratica sanitaria. Il documento
considera una serie di fattori di rischio che possono inficiare la sicurezza dâuso delle acque,
richiamando gli attuali quadri normativi che regolano la gestione degli impianti e la qualitĂ
delle acque.
La strategia di elezione su cui gli esperti convergono consiste in unâanalisi olistica dei rischi
di origine multifattoriale e di natura dinamica che caratterizzano le strutture sanitarie, per il
controllo dei quali si raccomandano azioni specifiche in diversi ambiti: piani di sicurezza
dellâacqua; approvazione dei trattamenti, materiali e prodotti a contatto con le acque su
certificazione di parte terza; responsabilitĂ di Struttura sanitaria, installatori e manutentori
degli impianti; multidisciplinarietĂ e interazione tra professionalitĂ sanitarie e tecnicoimpiantistiche;
formazione e ricerca; Comitato Infezioni Ospedaliere; coordinamento
regionale e nazionale; comunicazione; sostenibilitĂ delle risorse e risparmio idrico
5G champion:rolling out 5G in 2018
Abstract
The 5G CHAMPION Consortium will provide the first fully integrated and operational 5G prototype in 2018 â this effort is a major leap ahead compared to existing punctual technology trials, such as, e.g., Proof-of-Concept platforms focusing on mmWave communication in specific bands, etc. This paper describes the overall set-up including a synergetic combination of technologies such as beamforming based mmWave & Satellite service provisioning, virtualized infrastructure, software reconfiguration across the entire stack, accurate positioning and high-speed solutions. The key enablers are described in detail and related efforts in standards and regulation organizations are discussed
