Radio emissions from double RHESSI TGFs

2016

Abstract A detailed analysis of Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) terrestrial gamma ray flashes (TGFs) is performed in association with World Wide Lightning Location Network (WWLLN) sources and very low frequency (VLF) sferics recorded at Duke University. RHESSI clock offset is evaluated and found to experience changes on the 5 August 2005 and 21 October 2013, based on the analysis of TGF‐WWLLN matches. The clock offsets were found for all three periods of observations with standard deviations less than 100 μs. This result opens the possibility for the precise comparative analyses of RHESSI TGFs with the other types of data (WWLLN, radio measurements, etc.) In ca…

Gestione sostenibile delle foreste Mediterranee e uso energetico delle biomasse forestali residuali

2014

he book describes the reasons that led the Regional Department of Rural and Territorial Development to take part in the PROFORBIOMED Project. They can be summarized by the need to dispose of a tool for the sustainable management of all the state-owned forests of the Region. As a matter of fact, the Project aims at developing a model of sustainable forest management, through the recovery and reuse of wood scraps from ordinary silvicultural operations, to be used for the production of power and heat inside of a process adopting natural renewable energy sources. The main actions taken and the methodologies adopted are described, as well as the principles and instruments required for the settin…

Using On-Demand File Systems in HPC Environments

2019

In modern HPC systems, parallel (distributed) file systems are used to allow fast access from and to the storage infrastructure. However, I/O performance in large-scale HPC systems has failed to keep up with the increase in computational power. As a result, the I/O subsystem which also has to cope with a large number of demanding metadata operations is often the bottleneck of the entire HPC system. In some cases, even a single bad behaving application can be held responsible for slowing down the entire HPC system, disrupting other applications that use the same I/O subsystem. These kinds of situations are likely to become more frequent in the future with larger and more powerful HPC systems…

Buone pratiche di gestione forestale sostenibile. le azioni dimostrative condotte nell’area pilota in Sicilia

2014

Nell’ambito del progetto Proforbiomed, nel corso dell’implementazione dell’Azione Pilota 4 “Applicazione sul campo di buone pratiche di gestione forestale sostenibile” del Work Package 5 “Energie rinnovabili come opportunità per le economie locali e regionali”, a partire dalla selezione di Buone Pratiche, sono stati praticati interventi forestali dimostrativi su specifiche aree che sono state identificate all'interno delle Aree Pilota selezionate da ciascuno dei partner coinvolti in questa Azione Pilota. Finalità generale di questa Azione Pilota è stata quella di supportare la disseminazione di specifiche informazioni tecniche e dei risultati che derivano dalle differenti attività previste …
