A reference architecture for archival systems with application to product models

2013

Nowadays, a major part of the information is in digital form. Digital preservation is essential to allowpeople to access information over time. From a computer science perspective, two major objectiveshave to be met to enable digital preservation: developing archival systems to manage the preserveddigital information, and select information representations that will facilitate the preservation. For complexinformation such as product models, these two objective are particularly hard to meet. Archivalsystems have to operate in a complex environment, interact with many different systems, and supportmay different business functions. Product model representations do not use all the possibilities…

Système sémantique pour la customisation dynamique des modèles d'information de la PLM

2013

We live in the information age. Data has become an essential asset for most everyday situations and business interactions. The need to share data, to generate information, and create new knowledge from that data is common to all fields of research and all economic activity. Managing data is a critical, and sometimes costly, process. When not properly defined, data might become incomplete, inconsistent or, even worse, unusable. Requirements for data evolve and we must define new data or update existing data over the entire data lifecycle. Evolving data requirements is an important issue and a technological challenge as it is not possible to define, in advance, information structures that mee…

Noise characterization of analog to digital converters for amplitude and phase noise measurements

2017

International audience; Improvements on electronic technology in recent years have allowed the application of digital techniques in phase noise metrology where low noise and high accuracy are required, yielding flexibility in systems implementation and setup. This results in measurement systems with extended capabilities, additional functionalities and ease of use. In most digital schemes the Analog to Digital Converters (ADCs) set the ultimate performance of the system, therefore the proper selection of this component is a critical issue. Currently, the information available in literature describes in depth the ADC features only at frequency offsets far from the carrier. However, the perfo…

This thesis defines a new approach in urban and building facility management. A production and information management process of the building, its immediate environment and urban objects has been defined. It allows to manage these objects throughout their life cycle, in a concept called Urban Facility Management. This technology relies on an Urban Information Model to model all the information of cities and buildings in a dynamic and evolutive ontology. A mechanism for geometric and semantic levels of detail has also been defined to support the scalability of such a system. Indeed, the number of objects to be managed in a scene, compared to a building modeling system, is much higher, as the…

Le absidi nelle prime chiese normanne e nella Cappella Palatina di Palermo

2015

Nei primi decenni del XII secolo si realizzano in Sicilia numerosi edifici religiosi, le cui absidi seguono in genere i modelli bizantini, ma non mancano soluzioni originali. Tra le chiese basiliane del Val Demone si distingue quella dei Santi Pietro e Paolo a Casalvecchio Siculo (1117-1172), la cui abside centrale assume esternamente la forma di una torretta a pianta rettangolare, che include due nicchie pentagonali negli spazi di raccordo con la curva interna. Tutte e tre le absidi della chiesa di Sant’Andrea a Piazza Armerina (ante 1148) presentano esternamente un profilo rettilineo e la massiccia struttura muraria ingloba la torre campanaria. Nella cappella palatina di Palermo, consacra…
