HBIM in a semantic 3D GIS database

This work describes the different attempts and the consequent results derived from the integration of an HBIM model into an already structured spatial database (DB) and its 3D visualisation in a GIS project. This study is connected to the European ResCult (Increasing Resilience of Cultural Heritage) project where a DB for multiscale analyses was defined. To test the methodology proposed, the case study of Santa Maria dei Miracoli church in Venice was chosen since it represents a complex architectural heritage piece in a risk zone, it has been subject to a vast restoration intervention in the recent past but a digital documentation and model concerning it was missing. The 3D model of the church was structured in Revit as a HBIM, with the association of different kind of information and data related to the architectural elements by means of ‘shared parameters’ and ‘system families’. This procedure allows to reach an even higher Level of Detail (LOD4), but lead to some issues related to the semantic and software interoperability. To solve these problems the existing DB for the resilience of cultural heritage was extended adding a new entity representing the architectural elements designed in the BIM project. The aim of the test is to understand how the data and attributes inserted in the HBIM are converted and handled when dealing with a GIS DB, stepping from the IFC to the CityGML standard, through the FME software

HBIM in un database GIS 3D semantico

Questo lavoro descrive i diversi tentativi e i conseguenti risultati derivati dall’integrazione di un modello HBIM (Historical Building Information Modeling) in un database (DB) spaziale strutturato e la sua visualizzazione 3D in ambiente GIS. Si tratta di uno studio collegato al progetto europeo ResCult (“Increasing Resilience of Cultural Heritage”), nel cui ambito è stata definita la struttura di un DB per analisi multiscala finalizzate a supportare il patrimonio soggetto a rischio. Per testare la metodologia proposta, è stato scelto il caso studio della Chiesa di Santa Maria dei Miracoli a Venezia, situata sulle sponde di un canale, e dunque in una zona a rischio di inondazione. L’edificio presenta elevati valori storico-artistici, anche per il singolare rivestimento di marmi policromi. Il modello digitale 3D della Chiesa è stato generato con strategia HBIM in Revit, associando diversi tipi di informazioni in relazione agli elementi architettonici mediante “parametri condivisi” e “famiglie di sistema”. Questa procedura consente di raggiungere un alto livello di dettaglio (LOD4), ma presenta alcuni problemi dovuti all’interoperabilità semantica e geometrica nell’integrazione in ambiente GIS. Per risolvere questi problemi il DB ResCult è stato esteso aggiungendo una nuova entità che mira a rappresentare gli elementi architettonici modellati nel progetto BIM. Lo scopo dello studio è quello di investigare la conversione e la gestione di dati creati come HBIM all’interno di un ambiente GIS, sfruttando gli standards IFC e CityGML mediante l’utilizzo del software FME di Safe Software

HBIM-GIS Integration: From IFC to CityGML Standard for Damaged Cultural Heritage in a Multiscale 3D GIS

This study describes the technical-systemic and conceptual-informative interoperability tests for the integration of a Historic Building Information Modeling (HBIM) model in a 3D Geographic Information System (GIS) environment aimed to provide complete and useful documentation for multiscale analyses on cultural heritage particularly exposed to risks. The case study of the San Lorenzo Church in Norcia (Italy) has been chosen given the urgent need to update the existing documentation for its protection and conservation issues, due to the extensive damage suffered after the series of earthquakes that occurred in central Italy starting from summer 2016. Different tests to evaluate two levels of conceptual interoperability (technical and semantic) when importing the HBIM model into a GIS environment were performed, whether with commercial software or with open source ones (ArcGIS Pro and QGIS, respectively). A data integration platform (Feature Manipulation Engine, FME) has been used for converting the IFC (Industry Foundation Classes) data format into the GML (Geography Markup Language) format, in order to obtain a unique and unified model and vocabulary for the 3D GIS project, structured with different levels of detail, according to CityGML standard. Finally, as HBIM-GIS integration is considered, the loss of geometric and informative data has been taken into account and evaluated

DEVELOPMENT OF AN INTEGRATED BIM-GIS MANAGEMENT TOOL FOR MAINTENANCE PLAN OF HISTORICAL HERITAGE

The planned maintenance of cultural heritage (CH), in recent years, has been strongly supported by innovations in the digital field and, in particular, by digital models. In this framework, Main10ance, an INTERREG project, aims to implement a plan of maintenance and conservation of the historical cultural heritage. The case study is the system of the Sacri Monti of northern Italy and Switzerland, groups of chapels and other architectural artefacts. The design phases are divided into: survey of the historical architectural heritage present; data processing and realisation of three-dimensional models with the help of BIM software; integration of the same in the geographical context through GIS support; creation of a database (DB) which creates interoperability between the various domains and which collects information on the characteristics of the heritage for maintenance and conservation purposes; possibility to make the information associated with 3D models accessible through demonstrators that allow interrogation of the DB and the models themselves. The data have been entered (planned maintenance records, history of activities, etc.), convey them into the DB structured according to the INSPIRE Directive (2007/2/EC, Infrastructure for spatial information in Europe) and CityGML standard with its Level of Detail – LODs) for the GIS representation and IFC for the BIM. The Italian National Unification (UNI) norms have also been considered for the DB design

Taste and smell disorders in COVID-19 patients: role of Interleukin-6

The rapid recovery of smell and/or taste functions in COVID-19 patients could be attributed to a decrease in Interleukin-6 levels rather than central nervous system ischemic injury or viral damage to neuronal cells. To correlate Interleukin-6 levels in COVID-19 patients with olfactory and/or gustatory dysfunctions and to investigate the role of IL-6 in the onset of these disorders. This observational study investigated 67 COVID-19 patients with taste and/or smell disorders, who did not require intensive care admission, admitted at COVID Hospital of Policlinico of Bari from March to May 2020. Interleukin-6 was assayed to COVID-19 patients with taste and/or smell disturbances at the time of admission and at the time of swab negativization. At the same time, patients have been given a specific survey to evaluate the severity of taste and/or smell disturbances. Of 125 patients with smell and/or taste dysfunctions at onset of disease, 67 fulfilled the inclusion criteria, while 58 were excluded because 35 of them required intensive care admission, 5 were unable to answer, 5 deceased, 7 had finished chemotherapy recently and 5 refused. The evaluation of taste and/or smell disorders was carried out using a survey performed at the time of admission and at the time of swab negativization. Sino-nasal outcome test 22 (SNOT-22) was used as a reference for olfactory function assessment and Taste and Smell Questionnaire Section of the US NHANES 2011–2014 protocol (CDC 2013b) was used as reference for gustatory function assessment. A venous blood sample was taken for each patient to measure IL-6 levels upon entry and at swab negativization. Interleukin-6 levels in COVID-19 patients in relation with olfactory and/or gustatory disorders from the time of their admission to the time of swab negativization. Statistically significant correlations were obtained between the decrease of Interleukin-6 levels and the improvement of smell (p value<0,05) and taste (p=0,047) functions at swab negativization. The acquired results demonstrate the key role of Interleukin-6 in the pathogenesis of chemosensitive disorders in COVID-19 patients

Electrocardiographic characteristics of right-bundle-branch-block premature ventricular complexes predicting absence of left ventricular scar in athletes with apparently structural normal heart

Background and aims: Left ventricular scar is an arrhythmic substrate that may be missed by echocardiography and diagnosed only by cardiac magnetic resonance (CMR), which is a time-consuming and expensive imaging modality. Premature ventricular complexes (PVCs) with a right-bundle-branch-block (RBBB) pattern are independent predictors of late gadolinium enhancement (LGE) but their positive predictive value is low. We studied which electrocardiographic features of PVBs with a RBBB pattern are associated with a higher probability of absence of an underlying LGE. Methods and results: The study included 121 athletes (36±16 years; 48.8% men) with monomorphic PVCs with a RBBB configuration and normal standard clinical investigations who underwent CMR. LGE was identified in 35 patients (29%), predominantly in those with PVCs with a superior/intermediate axis (SA-IntA) compared to inferior axis (IA) (38% vs 10%, p=0.002). Among patients with SA-IntA morphology, the contemporary presence of qR pattern in lead aVR and V1 was exclusively found in patient without LGE at CMR (51.0% vs 0%, p< 0.0001). Among patients with IA, the absence of LGE correlated to a narrow ectopic QRS (145±16 vs 184±27 msec, p< 0.001). Conclusions: Among athletes with apparently idiopathic PVCs with a RBBB configuration, the presence of a concealed LGE at CMR was documented in 29% of cases, mostly in those with a SA-IntA. In our experience, the contemporary presence of qR pattern in lead aVR and V1 in PVCs with RBBB/SA-IntA morphology or, on the other hand, a relatively narrow QRS in PVCs with an IA, predicted absence of LGE

The SPES High Power ISOL production target

SPES (Selective Production of Exotic Species) is a facility under construction at INFN-LNL (Istituto Nazionale di Fisica Nucleare - Laboratori Nazionali di Legnaro), aimed to produce intense neutron-rich radioactive ion beams (RIBs). These will be obtained using the ISOL (Isotope Separation On-Line) method, bombarding a uranium carbide target with a proton beam of 40MeV energy and currents up to 200 μA. The target configuration was designed to obtain a high number of fissions, up to 1013 per second, low power deposition and fast release of the produced isotopes. The exotic isotopes generated in the target are ionized, mass separated and re-accelerated by the ALPI superconducting LINAC at energies of 10AMeV and higher, for masses in the region of A = 130amu, with an expected rate on the secondary target up to 109 particles per second. In this work, recent results on the R&D activities regarding the SPES RIB production target-ion source system are reported
