USO DEI PALMARI GNSS PER L’AGGIORNAMENTO CARTOGRAFICO: IL CASO STUDIO DEL COMUNE DI ROCCAMENA (PA)
2012
This work is an example of survey for the map update and run with handheld GNSS and differential corrections data through the network of permanent stations. This case study is about urban drainage systems and lighting subnets within a limited area of the town of Roccamena, Italy. The survey has the primary target the planning of engineering data needed to implement a GIS, the study was performed as mode NRTK with correction VRS, affected, in particular, the wells of public lighting, the wells of white water and sanitation, in addition to the drains around the town, on a total area of approximately 33 square kilometers. Once homogenized the data was developed a Geographic Information System …
SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study
2021
Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in su…
UN SIT PER IL PPE DEL CENTRO STORICO DI PALERMO: IL CASO STUDIO DEL MANDAMENTO CASTELLAMMARE
2015
In this work a Geographic Information System was realised at the service of municipal administration of Palermo, to integrate, manage and store city plan information regarding the urban district Castellammare whereof detailed executive plan of inner city, correlating basic cartography, current urban instrument, cadastral cartography, current restriction schemes, monumental and historical monuments, street numbers and street network. Quantum GIS vers. 1.8 of Free and Open-Source Software (FOSS) community was exclusively utilized to the fulfilment of GIS. To the experimentation and the fulfilment of WebGIS a free server was used in cloud on the Amazon, where a virtual machine, based on MapSer…
Meridiana Interrogazioni Temporali: Un’applicazione per l’analisi dei messaggi dalle stazioni permanenti
2009
In questo lavoro, si riporta una sperimentazione ancora in corso di approfondimento, inerente la realizzazione di un’applicazione software, Meridiana Interrogazioni Temporali, che possa analizzare con continuità i messaggi inviati attraverso posta elettronica all’Amministratore della Rete di Stazioni Permanenti GNSS. L’archivio sfrutta i messaggi trasmessi da uno dei server della infrastruttura geodetica (che raccoglie i dati per il postprocessamento), nel periodo temporale che va dal 2007 al 2009, con riferimento alle segnalazioni relative alla Rete di Stazioni Permanenti realizzata in Sicilia e gestita dall’Università di Palermo, nell’ambito di programmi di rilevante interesse nazionale. …
The ALMA REBELS Survey: The First Infrared Luminosity Function Measurement at $\mathbf{z \sim 7}
2023
We present the first observational infrared luminosity function (IRLF) measurement in the Epoch of Reionization (EoR) based on a UV-selected galaxy sample with ALMA spectroscopic observations. Our analysis is based on the ALMA large program Reionization Era Bright Emission Line Survey (REBELS), which targets 42 galaxies at $\mathrm{z=6.4-7.7}$ with [CII] 158$\micron$ line scans. 16 sources exhibit a dust detection, 15 of which are also spectroscopically confirmed through the [CII] line. The IR luminosities of the sample range from $\log L_{IR}/L_\odot=11.4$ to 12.2. Using the UVLF as a proxy to derive the effective volume for each of our target sources, we derive IRLF estimates, both for de…
Un WEBGIS Open Source a supporto dei rilievi GPS in Sicilia
2011
Con il rapido sviluppo di Internet, degli ultimi anni, i sistemi informativi geografici basati sull’utilizzo del Web sono diventati un argomento di forte interesse per il settore dei GIS. Il WEBGIS è uno strumento software, basato su sistemi di reti locali o geografiche e su un’interfaccia semplificata operante tramite browser Internet, che permette l’accesso a banche dati geografiche, anche a persone non esperte del settore. Tramite tale strumento è possibile visualizzare contestualmente informazioni geografiche organizzate su livelli informativi tematici, anche caratterizzati da diverso sistema di riferimento geografico ed eseguire, tramite un’interfaccia Web semplificata, parte delle ope…
Il GIS come strumento di fruizione territoriale e valorizzazione turistica
2013
The goal of this work has been to achieve a Geographic Information System, using innovative cartographic representation of the land and landscape, which can provide to the end users an easier and immediate access regarding tourist, cultural and environmental information. This is an ongoing research, carried out in collaboration with the Department of Civil, Engineering, Environmental, Aerospace, Materials (DICAM) of University of Palermo, with the objective to 548 Atti 17a Conferenza Nazionale ASITA - Riva del Garda 5-7 novembre 2013 achieve a complete integration between software used only by qualified specialists in the field and online platforms display. To experience this work, has been…
