Experimental induction of psychogenic illness in the context of a medical event and media exposure
Authors: Broderick, PhD Joan E. , Kaplan-Liss, MD, MPH Evonne , Bass, MPH Elizabeth
Published: January 2019

Objectives: Mass psychogenic illness can be a significant problem for triage and hospital surge in disasters; however, research has been largely limited to posthoc observational reports. Reports on the impact of public media during a disaster have suggested both salutary as well as iatrogenic psychological effects. This study was designed to determine if psychogenic illness can be evoked and if media will exacerbate it in a plausible, controlled experiment among healthy community adults.Methods: A randomized controlled experiment used a simulated biological threat and elements of social contagion—essential precipitants of mass psychogenic illness. Participants were randomly assigned to one of three groups: no-intervention control group, psychogenic illness induction group, or psychogenic illness induction plus media group. Measures included three assessments of symptom intensity, heart rate, blood pressure, as well as questionnaires to measure potential psychogenic illness risk factors.Results: The two psychogenic induction groups experienced 11 times more symptoms than the control group. Psychogenic illness was observed in both men and women at rates that were not significantly different. Higher rates of lifetime history of traumatic events and depression were associated with greater induction of illness. Media was not found to exacerbate symptom onset.Conclusions: Psychogenic illness relevant to public health disasters can be evoked in an experimental setting. This sets the stage for further research on psychogenic illness and strategies for mitigation.

The interagency strategic plan for research and development of blood products and related technologies for trauma care and emergency preparedness 2015-2020
Authors: Pusateri, PhD Anthony E. , Homer, PhD Mary J. , Rasmussen, MD Todd E. , Kupferer, DHSc Kevin R. , Hoots, MD W. Keith
Published: January 2019

Intensive blood use is expected to occur at levels, which will overwhelm blood supplies as they exist with current capabilities and technologies, both in civilian mass casualty events and military battlefield trauma. New technologies are needed for trauma care, and specifically to provide safer, more effective, and more logistically supportable blood products to treat patients with, or at risk of developing, acquired bleeding disorders resulting from trauma, acute radiation exposure, or other causes. Three of the primary agencies with major research and development programs related to blood products, the Biomedical Advanced Research and Development Authority (BARDA), the Department of Defense (DoD), and the National Heart, Lung, and Blood Institute are uniquely positioned to partner in addressing these issues, which have significant implications for each respective agency, as well as for the US population. Providing leadership, coordination, and oversight for the Food and Drug Administration’s national and global health security, counterterrorism, and emerging threats portfolios, the US Food and Drug Administration Office of Counterterrorism and Emerging Threats serves in a critical advisory and facilitative role regarding development and availability of blood products. This plan is informed by the 2012 PHEMCE Strategy (US Department of Health and Human Services, 2012), the 2007 “Shaping the Future of Research” Strategic Plan for the National Heart, Lung, and Blood Institute, the 2011 BARDA Strategic Plan, the DoD Combat Casualty Care Research Program: Policy Review, the 2015 DoD Hemorrhage and Resuscitation Research and Development Strategic Plan, and more than 30 participants from other agencies who participated in planning.

Published: January 2019

Introduction

Familial Mediterranean fever (FMF) is an autosomal recessive disease. It is characterized by recurrent crises of fever and serosal inflammation. Although FMF patients are symptom free in between attacks, subclinical inflammation continues during the attack-free period. Such patients with inflammatory status have an increased risk of atherosclerotic cardiovascular complications. We attempted to elucidate the role of arterial wall thickening as a predictor of early atherosclerosis in children affected by FMF and to clarify the links between carotid intima media thickness and the markers of subclinical inflammation serum amyloid A (SAA), erythrocyte sedimentation rate (ESR), neutrophil-to-lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR).

Material and methods

It is a case control study. The study comprised 45 Egyptian children diagnosed with FMF and 45 healthy children of matched age and sex who served as controls, without family history or clinical manifestations suggestive of FMF. Laboratory investigations included complete blood count, NLR, PLR, ESR, C-reactive protein and lipid profile. Serum amyloid A levels were determined in both groups using enzyme linked immunosorbent assay. Assessment of the common carotid artery intima media thickness (CIMT) in the FMF patients was carried out.

Results

The level of SAA was significantly higher in patients than the control subjects with a mean value of 38.30 ng/ml and 23.43 ng/ml respectively (p < 0.001). Our patients showed significantly higher PLR when compared to controls (p < 0.001). The mean right and left carotid intima media thickness in patient and control groups showed a highly significant difference (p = 0.005 and 0.036 respectively).

Conclusions

The mean carotid intima media thickness is higher in cases than the control group. Hence carotid intima media thickness may be used as a tool in the prediction of any atherosclerotic burden in those children.
Kernpunten van de controle en de transparantie erover in bestuursverslag, verslag van de raad van commissarissen en de jaarrekening
Authors: De Bos Auke , De Jong Martijn , Strating Henk
Published: January 2019

De uitgebreide controleverklaring geeft meer informatie over de controle. Omdat het bestuur en de commissarissen verantwoordelijk zijn voor de verslaggeving van de onderneming mag verwacht worden dat zij in de jaarrekening en in hun verslagen ook ingaan op de onderwerpen die de accountant bespreekt als kernpunten van de controle. In de praktijk blijkt dit in Nederland voor verbetering vatbaar, waarbij geleerd kan worden van de ervaringen in het Verenigd Koninkrijk.

De Corporate Governance Code van het Verenigd Koninkrijk geeft uitvoerige voorschriften voor de rapportage door auditcommissies, welke in de Nederlandse code ontbreken. Hierdoor is de kwaliteit van de audit committee reports in het Verenigd Koninkrijk aanzienlijk hoger dan de kwaliteit van de Nederlandse verslagen van de raad van commissarissen. Daarom pleiten we ervoor in de Nederlandse code soortgelijke bepalingen op te nemen voor raden van commissarissen/auditcommissies als in het Verenigd Koninkrijk, zodat transparantie en daarmee de rollen en verantwoordelijkheden van bestuur, commissarissen en de accountant duidelijk en consistent zijn. Echter ook zonder meer gedetailleerde regelgeving zouden we meer verwachten van de kwaliteit van de verslaggeving door ondernemingen. De controleverklaring bevat in Nederland in een aantal gevallen meer informatie dan de onderneming zelf communiceert.

Om de transparantie van verslaggeving te verbeteren is het nodig dat het bestuur rapporteert over de belangrijkste risico’s met een financiële impact op de jaarrekening. De raad van commissarissen brengt als intern toezichthouder verslag uit over de wijze van toezicht en hoe is omgegaan met en transparantie wordt gegeven over de materiële risico’s en onzekerheden. Vervolgens beschrijft de accountant hoe hij deze risico’s heeft geadresseerd in de controle.
Physiological and biochemical responses of Emiliania huxleyi to ocean acidification and warming are modulated by UV radiation
Authors: Tong Shanying , Hutchins David A. , Gao Kunshan
Published: January 2019

Abstract. Marine phytoplankton such as bloom-forming, calcite-producing
coccolithophores, are naturally exposed to solar ultraviolet radiation (UVR,
280–400 nm) in the ocean's upper mixed layers. Nevertheless, the effects of
increasing carbon dioxide (CO2)-induced ocean acidification and warming have rarely
been investigated in the presence of UVR. We examined calcification and
photosynthetic carbon fixation performance in the most cosmopolitan
coccolithophorid, Emiliania huxleyi, grown under high
(1000 µatm, HC; pHT: 7.70) and low (400 µatm,
LC; pHT: 8.02) CO2 levels, at 15 ∘C,
20 ∘C and 24 ∘C with or without UVR. The HC
treatment did not affect photosynthetic carbon fixation at 15 ∘C,
but significantly enhanced it with increasing temperature. Exposure to UVR
inhibited photosynthesis, with higher inhibition by UVA (320–395 nm) than
UVB (295–320 nm), except in the HC and 24 ∘C-grown cells, in which
UVB caused more inhibition than UVA. A reduced thickness of the coccolith layer
in the HC-grown cells appeared to be responsible for the UV-induced
inhibition, and an increased repair rate of UVA-derived damage in the
HC–high-temperature grown cells could be responsible for lowered UVA-induced inhibition.
While calcification was reduced with elevated CO2 concentration,
exposure to UVB or UVA affected the process differentially, with the former
inhibiting it and the latter enhancing it. UVA-induced stimulation of calcification was
higher in the HC-grown cells at 15 and 20 ∘C, whereas at
24 ∘C observed enhancement was not significant. The calcification
to photosynthesis ratio (Cal ∕ Pho ratio) was lower in the HC treatment,
and increasing temperature also lowered the value. However, at 20 and
24 ∘C, exposure to UVR significantly increased the Cal ∕ Pho
ratio, especially in HC-grown cells, by up to 100 %. This implies that
UVR can counteract the negative effects of the “greenhouse” treatment on
the Cal ∕ Pho ratio; hence, UVR may be a key stressor when considering the
impacts of future greenhouse conditions on E. huxleyi.
Assessing the characteristics and drivers of
compound flooding events around the UK coast
Authors: Hendry Alistair , Haigh Ivan D. , Nicholls Robert J. , Winter Hugo , Neal Robert , Wahl Thomas , Joly-Laugel Amélie , Darby Stephen E.
Published: January 2019

Abstract. In low-lying coastal regions, flooding arises from oceanographic (storm surges plus tides and/or waves), fluvial (increased river discharge) and/or pluvial (direct surface runoff) sources. The adverse consequences of a flood can be disproportionately large when these different sources occur concurrently, or in close succession, a phenomenon that is known as ‘compound flooding’. In this paper, we assess the potential for compound flooding arising from the joint occurrence of high storm surge and high river discharge around the coast of UK, using observed sea level and river discharge data. First, we map the spatial dependence between high skew surges and high river discharge, considering 326 river stations linked to 33 tide gauge sites. We find that the joint occurrence of high skew surges and high river discharge occurs more frequently during the study period (15–50 years) at sites on the south-west and west coasts of the UK (between 3 and 6 joint events per decade), compared to sites along the east coast (between 0 and 1 joint events per decade). Second, we investigate the meteorological conditions that drive compound (i.e. joint occurrence of high skew surge and high river discharge) and non-compound events (i.e. high skew surge or high river discharge only) events across the UK. We show, for the first time, that spatial variability in the dependence and number of joint occurrences of high skew surges and high river discharge is driven by meteorological differences in storm characteristics. On the west coast of the UK, the storms that generate high skew surges and high river discharge are typically similar in characteristics and track across the UK on comparable pathways. In contrast, on the east coast, the storms that typically generate high skew surges are mostly distinct from the types of storms that tend to generate high river discharge. Third, we briefly examine how the phase and strength of dependence between high skew surge and high river discharge is influenced by the characteristics (i.e. flashiness, size, elevation gradient) of the corresponding river catchments. We find that high skew surges tend to occur more frequently with high river discharge at catchments with a lower base flow index, smaller catchment area and steeper elevation gradient. In catchments with a high base flow index, large catchment area and shallow elevation gradient the peak river flow tends to occur several days after the high skew surge. The previous lack of consideration of compound flooding means that flood risk has likely been underestimated around UK coasts, particularly along the southwest and west coasts. It is crucial that this is addressed in future assessments of flood risk and flood management approaches.
RECONSTRUCTION OF URBAN SITES FROM PHOTOS
Authors: Agnello F.
Published: January 2019

Abstract. This paper reports the results of an experiment that aims at the virtual reconstruction of a urban site that has been partially reshaped during the 20th century; the reconstruction process is based on period photos. The chosen case study is the eldest harbour of Palermo, named ‘Cala’; the site was bombed during World War II and new buildings took the place of the ruined ones. Two period photos, taken from an aircraft, document the buildings that were destroyed by bombs. The 3D restitution process used the ‘inverse’ projection from period photos (2D) to the virtual space (3D) ; the first step was therefore addressed to the calculation of the inner parameters (focal length, principal point coordinates) and of the cameras’ pose, i.e. their position and orientation. The data needed for these calculations were extracted from the 3D laser scanning survey of those buildings that appear in photos and that are still on site. The calculation of inner parameters and poses has been computed with a motion tracking commercial package. The second part of the paper focuses a process for the fruition of virtual reconstructions, based on the alignment of real panoramic images, generated by photos taken on site, and of virtual panoramic images, extracted from the 3D reconstruction model; the proposed method uses SfM photogrammetric tools.
3D STRUCTURE ANALYSIS: ARCHITECTURE AS AN EXPRESSION OF THE TIES BETWEEN GEOMETRY AND PHILOSOPHY
Authors: Bellone T. , Mussio L. , Porporato C.
Published: January 2019

Abstract. In recent decades many Geomatics-based methods have been created to reconstruct and visualize objects, and these include digital photogrammetry, Lidar, remote sensing and hybrid techniques. The methods used to process such data are the result of research straddling the fields of Geomatics and Computer Vision, and employ techniques arising from approaches of analytical, geometric and statistical nature. One of the most fascinating fields of application concerns Architecture, which, moreover, has always depended on Mathematics generally and, more specifically, on Geometry. Throughout history the link between Geometry and Architecture has been strong and while architects have used mathematics to construct their buildings, geometry has always been the essential tool allowing them to choose spatial shapes which are aesthetically appropriate. Historically, mathematics and philosophy have been interrelated; many philosophers of the past were also mathematicians. The link between Philosophy and Architecture is twofold: on the one hand, philosophers have discussed what architecture is, on the other, philosophy has contributed to the development of architecture. We will deal with the ties between Architecture, Geometry and Philosophy over the centuries. Although there are artistic suggestions that go beyond time and space, and there are genial precursors, we can identify, in principle, some epochs: the ancient era, the modern era, and finally the contemporary epoch, from the crisis of positivistic sciences to globalisation.
FROM THE INTEGRATED SURVEY OF HISTORIC SETTLEMENTS TO THE PATTERN BOOK WITHIN THE BIM
Authors: Bianconi F. , Filippucci M. , Amoruso G. , Bertinelli M.
Published: January 2019

Abstract. The object of the study is the survey of minor historic settlements through integrated architectural survey techniques, the BIM modelling for the management of information at multiple levels, and the definition of pattern books to describe the qualities of the place. The research on cultural heritage representation made in Umbria, taking as a case study the historic hamlet of Lizori, a settlement located over the hill between Foligno and Spoleto in the town of Campello sul Clitunno (PG). It was selected as a paradigm of minor village and an experimental model to provide useful reference to reconstruct strategies, which is so important in the area recently affected by seismic events. The purpose of the research is therefore focused on finding a modus operandi in the management of multiple and uneven information. The goal is then to create a digital informative model functional to the conservation and restoration process and a knowledge-based reference for further study.

Published: January 2019

Abstract. This abstract illustrates an interdisciplinary research project which focuses on the study, conservation and enhancement, through 3D digitization and virtual fruition, of an asset of great naturalistic, historical and ethnoanthropological value: Grotta dei Pipistrelli of Pantalica Nature Reserve (Sortino, SR). The cave (located in the Calcinara necropolis) is characterized by a great beauty as well as by a high cultural relevance and a remarkable scientific importance. In 2005, it awarded the UNESCO World Heritage title for its high historic, archaeological and speleological profile. Despite the site is being studied by specialists in chiropterofauna, nowadays there is not a comprehensive and reliable documentation of the plano-altimetric morphology of the cave, able to constitute a 3D database of essential information (e.g. morphological, geological, textural and wildlife information) for current and future studies, and to preserve the memory of this fragile ecosystem. The process of 3D digitization aims to create a model of the cave that allows us to enjoy this place, to explore it and to closely understand it in order to limit the anthropic pressure caused by visitors on the real site. Consequently, it is proposed the creation of a virtual environment, as a reproduction of the real one, which can be enjoyed by all categories of users.

Abstract. This paper presents part of the results of a larger research project that focused on the surveying and documenting of Roman theatres and amphitheatres in the Campania region as well as the testing of a virtual fruition system for the digital reconstruction of a case study: the Roman theatre of Benevento. The work was carried out by the research group at the Interdepartmental Urban/Eco Research Centre of the University of Naples Federico II in collaboration with Spinvector, a company specialized in ICT – Information and Communication Technology – which lead to the defining of a fruition system of Cultural Heritage applied to archaeological heritage.The project included 3D digital surveys of the study samples carried out using reality-based techniques, which allowed for the acquisition of metric, morphological, geometric and colorimetric data. This made it possible to elaborate three-dimensional models, based on the current configuration of the places as well as of the possible original reconfigurations.
SCAN-TO-BIM vs 3D IDEAL MODEL HBIM: PARAMETRIC TOOLS TO STUDY DOMES GEOMETRY
Authors: Capone M. , Lanzara E.
Published: January 2019

Abstract. The contribution is part of an interdisciplinary research that aims to address the problems of knowledge, interpretation and documentation of vulnerable structures such as the brick Renaissance domes in Campania (XV-XVI century). The goal is to analyze the relationship between Survey, Historic Building Information Modelling (HBIM) and 3D parametric models based on geometric rules from Treaties to study and to manage Cultural Heritage. HBIM is generally based on scan-to-BIM process that allows to generate 3D model from point cloud. The reverse modeling process, from a point cloud to parametric geometric model, poses a series of issues at the center of cultural debate that currently takes place around HBIM. The experimentation underway is part of this research field with the aim of using the parametric approach as a tool able to introduce an additional methodology for big data interpretation. Currently we can identify two different approaches for the construction of a HBIM system: building a simplified model by identifying the shape grammar or building the geometric components from survey without using pre-compiled objects libraries, following the scan to BIM logic. In our research we are going to identify an "hybrid" methodology. Generally the process is based on the knowledge and critical abilities of individual scholars, the idea is to increase the efficiency of the system through collaborative workflow forms that allow to optimize the processes through effective knowledge management actions. We are going to use procedural modeling techniques to generate HBIM domes library.

Published: January 2019

Abstract. This paper illustrates how BIM integration with GIS is approached as part of the workflow in creating Virtual Historic Dublin. A design for a WEB based interactive 3D model of historic buildings and centres in Dublin City (Virtual Historic Dublin City) paralleling smart city initiates is now under construction and led by the National Monuments at the Office of Public Works in Ireland. The aim is to facilitate the conservation and maintenance of historic infrastructure and fabric and the dissemination of knowledge for education and cultural tourism using an extensive Historic Building Information Model. Remote sensing data is now processed with greater ease to create 3D intelligent models in Historic BIM. While the use of remote sensing, HBIM and game engine platforms are the main applications used at present, 3D GIS has potential to form part of the workflow for developing the Virtual Historic City. 2D GIS is now being replaced by 3D spatial data allowing more complex analysis to be carried out, 3D GIS can define and depict buildings, urban rural centres in relation to their geometry topological, semantic and visualisation properties. The addition of semantic attributes allows complex analysis and 3D spatial queries for modelling city and urban elements. This analysis includes fabric and structural elements of buildings, relief, vegetation, transportation, water bodies, city furniture and land use.

Published: January 2019

Abstract. As the 3D laser scanning and photogrammetry technologies continue to mature, more and more applications founded in numerous areas. The realistic 3D models are mainly adopted for digital display uses, such as the 3D game, web showcases, head-mounted display, etc. While we are enjoying the vivid digital sceneries through different kinds of digital display screens, there are still challenges exist for the 3D printing application, especially for large size objects. In this article, we will present an approach on digitizing and 3D replicating large grottoes. Unlike 3D rendering, 3D printing requires high detailed shape data for the fabrication. Such demands cause many technical difficulties including huge data amount, accurate dense point cloud, high-resolution texture mapping. We chose cascade SfM, grouped MVS, automatic texture mapping to prepare the high definition colored 3D model for printing and painting references. Meanwhile, we optimized 3D printing procedure as well as post-processing, installation, lacquer and painting. Two replicas of 10- meter sized grottoes have been manufactured after four years of efforts, which have earned some appreciations from audiences.
RECREATING CULTURAL HERITAGE ENVIRONMENTS FOR VR USING PHOTOGRAMMETRY

Published: January 2019

Abstract. In this paper, we propose a workflow for recreating places of cultural heritage in Virtual Reality (VR) using structure from motion (SfM) photogrammetry. The unique texture of heritage places makes them ideal for full photogrammetric capture. An optimized model is created from the photogrammetric data so that it is small enough to render in a real-time environment. The optimized model, combined with mesh maps (texture maps, normal maps, etc.) looks like the original high detail model. The capture of a whole space makes it possible to create a VR experience with six degrees of freedom (6DoF) that allows the user to explore the historic place. Creating these experiences can bring people to cultural heritage that is either endangered or too remote for some people to access. The workflow described in this paper will be demonstrated with the case study of Myin-pya-gu, an 11th century temple in Bagan, Myanmar.
THE TOMB OF IPI: 3D DOCUMENTATION IN A MIDDLE KINGDOM THEBAN NECROPOLIS (EGYPT, 2000 BCE)
Authors: Echeverría E. , Celis F. , Morales A. , da Casa F.
Published: January 2019

Abstract. Due to the multiplicity of tombs in the area and the work of early archaeologists in Deir el-Bahari, the necropolis resembles a Swiss cheese. In addition, most of these monuments and their remains (coffin fragments, human remains, subsidiary structures) were left unpublished. A century later, the major purpose of the Middle Kingdom Theban Project of University of Alcala (MKTP-UAH) –led by the moudir (i.e. “director” in Arabic) Antonio Morales– is to document, understand, and publish all these monuments and findings left behind by previous expeditions. Such publications will shed light not only on the necropolis and owners of the monuments, but will also help to understand the beginning of the so-called Middle Kingdom, a golden age of the pharaonic period with a significant and impressive architecture. In fact, most of archaeologists take these tombs as patterns for this golden age, without taking into consideration that we do not know much about them.
INTERACTIVE IMAGE GEOLOCALIZATION IN AN IMMERSIVE WEB APPLICATION

Published: January 2019

Abstract. For a long time people have been interested in the past and history and how we can go back in time using a time machine. And while we cannot invent a time machine, at least not yet, we can create a virtual one. Our “virtual” time machine is an interactive web application that allows users to browse through and navigate within historical images (aerial/terrestrial photographs or postcards) that are projected on a 3D photogrammetric model (point cloud or 3D mesh), thus going back in time and interacting with historical 3D models and images. This was achieved by adopting a semiautomatic approach where the user identifies first 6 to 8 hints on the historical image and the photogrammetric model, then this information is used as an entry data to a photogrammetric software that computes the pose and orientation of the image. The purpose of this work, which is part of the ALEGORIA project, is to preserve cultural heritage, to give the users the opportunity to go back in time and study history of a place or simply discover how their hometown looked some years ago.
INTEGRATION OF SURVEYING TECHNIQUES TO DETECT THE IDEAL SHAPE OF A DOME: THE CASE OF THE ESCUELAS PÍAS CHURCH IN VALENCIA
Authors: Artese S. , Lerma J. L. , Aznar Molla J. , Sánchez R. M. , Zinno R.
Published: January 2019

Abstract. The three-dimensional (3D) documentation and surveying of cultural heritage can be carried out following several geomatics techniques such as laser scanning and thermography in order to detect the original 3D shape after applying reverse engineering solutions. In almost all cases, the integration of data collected by different instruments is needed to achieve a successful and comprehensive 3D model of the as-built architectural shape of the historical building. This paper describes the operations carried out by the authors to determine the as-built 3D model of the Escuelas Pias Church, related namely to the dome and circular nave. After the description of the church and historical notes, attention will be driven to the indirect registration results obtained with three different laser scanning software packages, highlighting similarities and differences, and the consequences while generating meshes. The 3D model carried out will then be described and the results of some investigations with regard to the hypotheses about the design of the dome and the origin of the alterations will be presented.
GENERATIVE ADVERSARIAL NETWORKS FOR SINGLE PHOTO 3D RECONSTRUCTION
Authors: Kniaz V. V. , Remondino F. , Knyaz V. A.
Published: January 2019

Abstract. Fast but precise 3D reconstructions of cultural heritage scenes are becoming very requested in the archaeology and architecture. While modern multi-image 3D reconstruction approaches provide impressive results in terms of textured surface models, it is often the need to create a 3D model for which only a single photo (or few sparse) is available. This paper focuses on the single photo 3D reconstruction problem for lost cultural objects for which only a few images are remaining. We use image-to-voxel translation network (Z-GAN) as a starting point. Z-GAN network utilizes the skip connections in the generator network to transfer 2D features to a 3D voxel model effectively (Figure 1). Therefore, the network can generate voxel models of previously unseen objects using object silhouettes present on the input image and the knowledge obtained during a training stage. In order to train our Z-GAN network, we created a large dataset that includes aligned sets of images and corresponding voxel models of an ancient Greek temple. We evaluated the Z-GAN network for single photo reconstruction on complex structures like temples as well as on lost heritage still available in crowdsourced images. Comparison of the reconstruction results with state-of-the-art methods are also presented and commented.

Published: January 2019

Abstract. The relationship between cultural heritage, digital technologies and visual models involves an increasingly wide area of research, oriented towards the renewal of archives and museums for the preservation and promotion of culture. Recent research activities are the result of the progressive strengthening of digital technologies and the needs of a new generation of “digital” users, which requires museums to update their means of communication using Semantic Web languages and technologies shaped by a social conceptualization of a graph-based representation of information.The growth of several digitized heritage collections increases the necessity of proper methodologies to develop a structured system able to access to these collections and the large amount of data, metadata and paradata related to the digitized objects in a structured and organized way, defining a set of collection information models (CIM), that considers not only the digitizing process but also the data collection process, layered by an Upper Ontology level structure, based on CIDOC-CRM.
3D AND 4D MODELLING IN BUILDING SITE WORKING CONTROL
Authors: Lucarelli M. , Laurini E. , De Berardinis P.
Published: January 2019

Abstract. The purpose of this contribution is to describe the use of the HBIM method for the management of the restoration building site applied to a historic building in the heart of the historic center of L'Aquila. The construction is located in a densely constructed area and it is characterized by a high spatial complexity with various types of limitations including: small external and internal spaces and interferences due to neighboring construction sites. The proposed method involves a particularly detailed organization of the construction site, simultaneously planning both the development of the working and the safety in order to have more transparency and more control of the information shared among stakeholders. This method consists in planning the Gantt diagram from general to detailed level, according to certain parameters that will be cross-examined and checked regurarly. A screening step has been carried out regarding the current situation, the proceedings to be undertaken and the stakeholders to be included. Thank to this, it has been possible to have automated processes to control not only geometrical interferences but also the ones related to the completion of the work in the interest of enhancing the risk management. Due to a 3D and 4D BIM modelling, there are been found advanced layouts and some timeliners that have allowed a rigourus control of the building process, particularly in the case of precise working and potencial changes that are common in building sites of this type.

Published: January 2019

Abstract. Despite photogrammetry has been longly used for 3D model production, the recent development of structure from motion based reconstructions and the spread of unmanned aerial vehicles (UAV) are increasing its usage even further. Actually, the combined use of nadir and oblique UAV photogrammetry allows to cross the bridge between close range and aerial photogrammetry, enabling the quick acquisition of images for detailed 3D model production. This paper assesses the accuracy of UAV photogrammetry in the reconstruction of a cultural heritage building, namely the Girifalco fortress (Cortona, Italy), and it evaluates advantages and issues of this kind of 3D model generation. Furthermore, this work aims also at investigating the possible use of the generated model in order to extract geometric information about the building. First, elementary geometric shapes are extracted from the photogrammetric point cloud: the results of this step can be exploited for enabling the automatic generation of compact models of the building, which can be useful for instance in 3D city modeling applications. Then, a proper analysis of the geometric information included in the extracted shapes can be used in order to extract semantic information (e.g. to classify windows and doors) and to detect damaged areas on the building walls.

Published: January 2019

Abstract. The objective of this article is to analyze the state-of-art regarding the construction process of the Gaussian Vaults of the Uruguayan civil engineer Eladio Dieste and to identify the elements that underlie the relationship between the constructive techniques and procedures within this specific structural typology and its resulting geometry. As complementary objectives, this research aims for the identification of the gaps in the registry of such constructive procedures. The essay focuses on the geometry of the Gaussian Vaults designed and built by Dieste, in a way that these rigid structural surfaces’ geometry had their original construction drawings redrawn and analyzed from the perspective of its construction technique by means of the Parametrical Modelling and Digital Fabrication of case studies.
EXISTING-BIM: INTEGRATED SURVEY PROCEDURES FOR THE MANAGEMENT OF MODERN ARCHITECTURE
Authors: Monaco S. , Siconolfi M. , di Luggo A.
Published: January 2019

Abstract. This paper is aimed at illustrating the operation workflow to create a BIM model of an existing building, by highlighting its process starting from photogrammetric acquisitions and indicating its critical elements as regards data structure and the following modeling. The subject of this study is a reinforced concrete building of the 1960s on six levels. At present, it is undergoing an extensive refurbishment with the purpose of converting its original function, from the US Navy Hospital into offices. Since it was possible to access archive documents concerning the executive design and to carry out even invasive surveys for acquiring specific data about building details, BIM modeling could refer to a significant amount of qualitative and quantitative data. This circumstance characterized the work steps of a BIM modeling which, although referred to an existing building, may also be applied to new constructions. Building technology has implicitly facilitated the identification of the constructive elements and the creation of a list, although the unusual shape of the structure has caused specific problems differently discussed and documented in the text.

Published: January 2019

Abstract. Applications of 3dscanning and digital manufacturing established a new understanding of the architectural space, making it possible to capture it at a specific time. The possibility to get them closer ease the recreation of a physical object. In the present work, different methodologies and post-production techniques are presented, starting from scans, and working computationally to prepare the models for additive manufacturing. To describe this workflow, two architectural examples are used: a historic façade of the XVI Century and the recent archaeological project, from II Century BC. The primary objective has been to get closer the world of 3D scanning and digital manufacturing. It has been focused on its application for the preservation of fragile cultural elements, not only in its conservation from natural disasters or human conflicts but also to study the possibility of replicating the elements and making them accessible in a digital way.

This work is carried out in collaboration with the Nihon University of Tokyo, the Alma Mater Studiorum University of Bologna, the Itabashi municipality and the Topcon industry. The work is preparatory for the development of the redevelopment project of the park, through the reuse of its buildings, the arrangement of the green and urban furniture pursuing the objectives of maintaining the historical memory of the place and its harmonization in the urban context, creating a further pole of attraction for citizens and visitors.
VIRTUAL HERITAGE FOR THE DISSEMINATION OF THE BARATTI IN 3D PROJECT
Authors: Nicastro G. , Puma P.
Published: January 2019

Abstract. The paper describes the final step of the Baratti in 3D project, aimed at the dissemination of the important archaeological heritage of the Etruscan city of Populonia (Tuscany, Italy). The chain of “data metrical surveying – 2D and 3D representation – communication” has been applied on the “Princes's tombs” of the monumental necropolis of San Cerbone and its finds to provide a detailed description of their context, workmanship, morphological characteristics and materials to realize the virtual recreation. The preservation of the finds from the excavations in two different museums far from the archaeological area (the Museo Archeologico Nazionale di Firenze and the Museo Archeologico del Territorio di Populonia, in Piombino) makes the understanding of the original context very difficult for visitors. Thus the “Baratti in 3D Project” has been conceived in order to document the tombs, their finds and produce the “virtual match” showing in its entirety the environmental and architectural provenance and material ritual context and in order to display in innovative visual approach this archaeological heritage. To complement the interactive platform, as a physical fallout of this project has been realized “A museum in every sense”, a permanent exhibition in the Museo Archeologico del Territorio di Populonia.

A FULLY AUTOMATED INCREMENTAL PHOTOGRAMMETRIC PROCESSING DEDICATED FOR COLLABORATIVE REMOTE-COMPUTING WORKFLOW
Authors: Pamart A. , Morlet F. , de Luca L.
Published: January 2019

Abstract. Image based-modeling practices in the field of Cultural Heritage studies are nowadays no longer seen as one-shot applications but as various and complex multimodal scenarios. Current use of SFM and photogrammetric methods implies their extensions to facilitate the management of complex multimodal data sets carried-out by different experts around a single heritage asset. In order to fully benefit of collaborative semantic enrichment of spatially oriented resources, a versatile and robust solution have been developed to enable incremental registration of image-sets within the web-based platform AIOLI. For this purpose, this paper will present an on-going development of a Totally Automated Co-registration and Orientations (TACO) work-flow.

Published: January 2019

Abstract. The Building Information Modeling (BIM) in the Architectural Heritage field is constantly proving to be a fertile ground for the experimentation of innovative systems for the enhancement and management of cultural heritage. Regarding to the management of the entire process, the building field is increasing in efficiency from the construction to the management phase; conversely, the approach to historical buildings opens up interesting and heterogeneous scenarios, according to different levels of complexity. The presented work is the result of a collaboration between the Politecnico di Torino and the Escuela Técnica Superior de Arquitectura of Granada: the main scope was to create an historic building information model (H-BIM) of the building that today hosts the Faculty of Architecture (ETSAG), taking into account its historical past from the sixteenth century up to the present day, as the result of many modifications, extensions and different use classifications over time. According to this, the BIM methodology can be considered as a bridge between the archive documentation and the digital model, proving to be an effective tool as a data repository, semantically oriented, not only constituted by geometry, but also by alpha-numerical attributes, improving in effectiveness if it is directly related to formal language object oriented.
PARAMETRIC SURFACES FOR AUGMENTED ARCHITECTURE REPRESENTATION

Published: January 2019

Abstract. Augmented Reality (AR) represents a growing communication channel, responding to the need to expand reality with additional information, offering easy and engaging access to digital data. AR for architectural representation allows a simple interaction with 3D models, facilitating spatial understanding of complex volumes and topological relationships between parts, overcoming some limitations related to Virtual Reality. In the last decade different developments in the pipeline process have seen a significant advancement in technological and algorithmic aspects, paying less attention to 3D modeling generation. For this, the article explores the construction of basic geometries for 3D model’s generation, highlighting the relationship between geometry and topology, basic for a consistent normal distribution. Moreover, a critical evaluation about corrective paths of existing 3D models is presented, analysing a complex architectural case study, the virtual model of Villa del Verginese, an emblematic example for topological emerged problems. The final aim of the paper is to refocus attention on 3D model construction, suggesting some "good practices" useful for preventing, minimizing or correcting topological problems, extending the accessibility of AR to people engaged in architectural representation.
