Survey and critical analysis of the church of S. Pietro a Coppito in L’Aquila

Starting from an integrated architectural survey, which uses synergistically multiple integrated digital technologies, the study proposes a reading of the church of S. Pietro a Coppito in the city center of L’Aquila. The image offered by the church nowadays is the result of a heavy restoration of the 20th century, that uncritically destroyed the pre-existing Baroque church, in an attempt to rediscover the medieval one largely destroyed by earthquakes and transformations in historical cont...

Il Building Information Modeling per la documentazione e gestione del patrimonio costruito: il caso studio del polo universitario di Coppito

information modelling in the management of building processes, the University of L’Aquila decided to digitize its real estate assets by producing BIM models of its buildings. The objective of this process, which is currently under development, is the possibility to maintain and manage its heritage more efficiently, thanks to the support of digital models in which to store, manage and share the different information regarding the buildings. The paper presents a first result of a research ...

Using the Reflectometric technique for monitoring the boiling flow dynamics in a once through steam generator

In control systems design for nuclear facilities, the correct choice for sensors, transducers and actuators is not an easy task when different options must be evaluated. In particular, for a Once Through Steam Generator (OTSG), the control of its boiling flow dynamics is usually performed with sensors that may be slow in response, must be placed all through the zone of interest (or need heavy mechanical modifications) and may not distinguish correctly when the liquid/steam interface is not so...

Real-time state identification of boiling water reactors using relevance vector machines

Automated state identification systems facilitate reactor monitoring and control of nuclear systems by consolidating information collected by deployed sensors. In the current paper, we present the use of relevance vector machines (RVM) for real-time state identification of boiling water reactors (BWR). In particular, RVM models utilize the incoming signals of interest and identify in real time the state of the BWR either as normal or as one of the transition states. Each of the RVM models is ...

IN-service inspection and on-line monitoring of inaccessible components in nuclear power plants using guided wave technology

One of the most challenging problems in the on-line monitoring of critical parameters of nuclear plants is the inspection of components that result inaccessible or difficult to reach. In this context, there is an increasing interest of the scientific community and industry for the use of Ultrasonic Guided Waves (UGW) for addressing this issue. In this work, the problem of the applicability of the UGW technique with magnetostrictive sensors to NPP structures is described, together with the out...
