Rilievi e indagini diagnostiche non distruttive per l’individuazione delle cripte - La Cattedrale di Ragusa

2014

I diversi operatori, che si occupano di Beni Storici e Culturali, si avvalgono sempre più spesso delle soluzioni tecnologiche avanzate offerte dalla moderna Geomatica, facendo ricorso ad integrazioni delle sue discipline, per meglio studiare, indagare e monitorare un bene di interesse storico. Oggi si tentano nuove integrazioni con altre discipline che, tradizionalmente, non riguardano il campo del rilievo propriamente detto. Questo è, ad esempio, il caso dello studio condotto sulla Cattedrale di San Giovanni a Ragusa, nel quale si è partiti dal rilievo laser scanning di una porzione della chiesa e del suo pregiatissimo pavimento, sotto il quale secondo uno schizzo dei primi anni del XIX se…

3D VIRTUAL CH INTERACTIVE INFORMATION SYSTEMS FOR A SMART WEB BROWSING EXPERIENCE FOR DESKTOP PCS AND MOBILE DEVICES

2018

Abstract. Recently, the diffusion of knowledge on Cultural Heritage (CH) has become an element of primary importance for its valorization. At the same time, the diffusion of surveys based on UAV Unmanned Aerial Vehicles (UAV) technologies and new methods of photogrammetric reconstruction have opened new possibilities for 3D CH representation. Furthermore the recent development of faster and more stable internet connections leads people to increase the use of mobile devices. In the light of all this, the importance of the development of Virtual Reality (VR) environments applied to CH is strategic for the diffusion of knowledge in a smart solution. In particular, the present work shows how, s…

Sharing on web 3D models of ancient theatres. A methodological workflow

2016

Abstract. In the last few years, the need to share on the Web the knowledge of Cultural Heritage (CH) through navigable 3D models has increased. This need requires the availability of Web-based virtual reality systems and 3D WEBGIS. In order to make the information available to all stakeholders, these instruments should be powerful and at the same time very user-friendly. However, research and experiments carried out so far show that a standardized methodology doesn’t exist. All this is due both to complexity and dimensions of geometric models to be published, on the one hand, and to excessive costs of hardware and software tools, on the other. In light of this background, the paper describ…

GLOBE BASED 3D GIS SOLUTIONS FOR VIRTUAL HERITAGE

2018

Abstract. During the last years, many solutions have been proposed for 3D Virtual Heritage representations. Recently, also new technologies for online gaming evolved, based on javascript libraries (WebGL), used to create and publish virtual interactive environments. They are based on recent Web browser’s functionalities, surpassing some limitations of VRML technologies. On the side of geospatial information, technology has evolved from desktop GIS to 2D WebGIS and globe applications. The use of globe applications is, today, very diffused due to its immediate and at the same time impressive representation of the earth surface and territories. These technologies have been, also, applied to Vi…

Immunological Markers for PML Prediction in MS Patients Treated with Natalizumab

2015

International audience; Natalizumab (NTZ), a monoclonal antibody recognizing the alpha4 integrin chain, has been approved for the treatment of active multiple sclerosis, but expose to the onset of a rare side effect, progressive multifocal leukoencephalopathy (PML). Estimating the individual risk of PML in NTZ-treated patients is a major challenge, and therapeutic strategies are mainly guided by the overall PML risk assessed by identified risk factors: JC virus (JCV) seropositivity, treatment duration (with peak incidence after 24 months), and the previous use of immunosuppressive therapies. Given that this stratification does not yet allow a precise individual prediction of PML, other pred…

E-maintenance platform: a business process modelling approach

2014

Las tecnologías de la información y la comunicación (TIC) se utilizan cada vez más en la sociedad y en los negocios. Las TIC se han convertido en un elemento clave para el desarrollo empresarial y la mejora de las actividades en todos los departamentos de una organización. Análogamente, la creciente importancia de los Sistemas de Gestión de Mantenimiento asistido por Ordenador (CMMS), Mantenimiento Basado en la Condición (CBM), y la aplicación de dispositivos remotos y funciones como el e-mantenimiento, han abierto grandes posibilidades para la optimización del mantenimiento. Estas técnicas han dado lugar a la aparición de retos tecnológicos, tales como la interoperabilidad entre diferentes…

Gli "scartafacci" di Attilio Bertolucci". Edizione critica

Il lavoro di ricerca condotto da Luciano Longo, su un gruppo di testi inediti di Attilio Bertolucci -stesi tra 1930 e 1940 e conservati presso l’Archivio di Stato di Parma- si è svolto sul doppio fronte della realizzazione di un’edizione critica secondo l’ecdotica tradizionale e, insieme, di un’edizione critica digitale secondo la codifica in XML (eXtensible Markup Language)-TEI (Text Encoding Iniative). Oltre a tali inediti, la tesi esamina pure -con la finalità di creare il corpus poetico degli anni Trenta- tutti i nuovi testimoni delle poesie edite intorno a quegli anni che la Palli Baroni non ha preso in considerazione nella sua edizione critica del 1997. La tesi di Longo, oltre a esser…

Tatouage des bases de données

2010

Database watermarking techniques allow for hiding information in a database, like a copyright mark. While watermarking methods are numerous in the multimedia setting, databases present various specificities. This work addresses some of them: how to watermark a numerical database while preserving the result of interesting aggregate queries, how to watermark a structured stream like a typed XML stream or a symbolic music score, how to watermark geographical data sets.

Removal of molecular contamination in low-energy RIBs by the isolation-dissociation-isolation method

Separation of atomic and molecular ions by ion mobility with an RF carpet

2021

Gas-filled stopping cells are used at accelerator laboratories for the thermalization of high-energy radioactive ion beams. Common challenges of many stopping cells are a high molecular background of extracted ions and limitations of extraction efficiency due to space-charge effects. At the FRS Ion Catcher at GSI, a new technique for removal of ionized molecules prior to their extraction out of the stopping cell has been developed. This technique utilizes the RF carpet for the separation of atomic ions from molecular contaminant ions through their difference in ion mobility. Results from the successful implementation and test during an experiment with a 600~MeV/u $^{124}$Xe primary beam are…
