Numerical Simulations of Projectile Nose Angle Effect in Ballistic Perforation of Double-Layered Steel Plates
Authors: Sun Wei Hai , Ju Gui Ling , Huang Xiao Tian , Pan Jing Wen
Published: May 2019

The purpose of this paper is to study the ballistic perforation resistance of double-layered steel plates subjected to impact by conical projectiles with different nose angles. Based on nonlinear finite element theory, different rigid projectiles vertically penetrating into double-layered Weldox 460E steel plates are simulated with LS-DYNA code. The configurations in the penetration process and failure modes of steel plates are given. The results of monolithic and layered targets are studied and compared for projectiles with different nose angles. It is revealed that compared to the monolithic plate, the double layer configuration is able to improve the ballistic limit for the target under impact by blunt-nose projectiles, and for sharp-nose projectiles the double layer configuration obviously weakens the ballistic resistance.

Colour associated thermal impacts: manifestation and contributing factors with reference to red and blue
Authors: Hettiarachchi A. A. , De Silva T. K. N. P.
Published: May 2019

Theory of colour – a long-established tradition of artists – differentiates between the impacts of warm and cool colours respectfully on human beings. The lack of scientific and statistically substantiated knowledge on aforesaid colour associated thermal perception (CTP) deems to hinder its optimum integration in creating responsive built environments. This investigation seeks scientific explanation on manifestation and contributing factors of CTP with reference to a warm colour (red-RTP) and a cool colour (blue-BTP). The hypothesised potentials of CTP to manifest as a psychological response, a biological response, a factor altering core body temperature or as an actual thermal sensation caused via the human skin (due to heat radiation emitted by coloured surfaces) were tested. A crossover experiment was executed with a sample of healthy male undergraduates (n=111) selected via stratified simple random sampling (age 19 – 30), under controlled laboratory conditions. Substantiating colour theory, subjects demonstrated a propensity to perceive red as warm/hot (64.2%) and blue as cool/cold (59.3%). As revealed by logistic regression, CTP neither manifests due to a fluctuation in core body temperature nor as an actual thermal sensation. It is a psychological response characterised by common as well as colour-specific factors. Accordingly, thermal impacts of colour could be integrated in indoor environments to psychologically manipulate the perceived thermal environment against the real thermal condition to achieve the desirable thermal milieu. This novel knowledge may provide insights for Architects, interior designers, relevant authorities and organisations to develop strategies incorporating thermal impacts of colour to achieve low-energy design.

Hemophagocytic lymphohistiocytosis is a life-threatening hyperinflammation caused by uncontrolled proliferation of activated lymphocytes and histiocytes. Often, Hemophagocytic lymphohistiocytosis is an acquired syndrome. We report a case of a 9 month-old-boy presented with hepatosplenomegaly, severe anemia requiring repeated transfusions, thrombocytopenia, hypertriglyceridemia and very high hyperferritinemia. These clinical features of Hemophagocytic lymphohistiocytosis prompted a wide infectious and auto-immune request to be performed.  After a wide diagnostic workup, he was referred to the immune hematologic unit, for hemophagocytic lymphohistiocytosis  suspicion with unknown cause.
Domestic water meter optimal replacement period to minimize water revenue loss
Authors: Moahloli Aluta , Marnewick Annlizé , Pretorius JHC
Published: May 2019

Water meter under-registration results in apparent losses and lost revenue for municipalities. Municipalities should scientifically determine the optimal replacement periods for the meters in their particular municipality, as this would result

in the formulation and implementation of appropriate meter replacement strategies and a reduction of apparent losses due to water meter inaccuracies. A water meter management database was analysed using the relative meter error method to determine if a relationship exists between domestic water meter age, total registered volume and accuracy, as well as the volume of apparent water losses caused by inaccuracies due to domestic water meter age and total registered volume. The net present value chain (NPVCn) method was used to determine the optimal domestic water meter replacement period. This study found no relation between water meter age and total registered volume. A relation was found between water meter age and accuracy and well as between total registered volume and accuracy. The median relative meter error was found to decrease with increasing water meter age and to increase from under-registration to over-registration as the total registered volume increased. The study also determined the volume of apparent water losses caused by domestic water meter inaccuracies due to age and total registered volume for this particular municipality to be 1.814 kL∙meter−1∙month−1, which translated to 2.81% of the municipality’s total system input volume. The optimal water meter replacement period of the municipality was determined using the NPVCn method to be at water meter ages of 9, 12 and 16 years and total registered volumes of 3 971, 5 162 and 6 750 kL at discount rates of 10%, 8% and 6%, respectively. This means that the municipality can now proactively replace its water meters so as to minimize the impact of meter inaccuracies on non-revenue water.
Determination of isotopic composition of rainwater to generate local meteoric water line in Thohoyandou, Limpopo Province, South Africa
Authors: Durowoju Olatunde S , Odiyo John O , Ekosse Georges-Ivo E
Published: May 2019

Hydrogen (D) and oxygen (18O) isotopic compositions of precipitation are useful tools to delineate the nature of precipitation, groundwater recharge and climatological investigations. This study investigated the isotopic composition of 12 rainfall occurrences at Thohoyandou, with the objective of generating the local meteoric water line (LMWL) and determining the factors controlling the isotopic composition of the rain. The delta (δ) values for D and 18O of the samples were determined using a Thermo Delta V mass spectrometer connected to a Gasbench. Thohoyandou rainwater showed a wide range of stable isotope values; δD values of the rainwater varied from −76.3‰ to +22.7‰ (SMOW) with a weighted mean of −9.8‰ and δ18O values ranged from −10.78‰ to +3.07‰ (SMOW) with a weighted mean of −2.7‰. δ-values of rainwater were more enriched during winter and more depleted during summer, due to the amount of rainfall and seasonal effect. The LMWL in Thohoyandou is defined by δD = 7.56δ18O + 10.64, which shows a similar slope to the global meteoric water line (GMWL) but with a slightly higher intercept, of 10.64‰ instead of 10‰. This implies that the process of rain formation in Thohoyandou occurred under equilibrium conditions which are not significantly affected by evaporation. The slightly higher d-intercept value above the GMWL reflects an additional supply of recycled moisture across the regions. This implies that there is no continental effect but inland moisture from various water bodies and vegetation.
Characterization of the performance of venturi-based aeration devices for use in wastewater treatment in low-resource settings
Authors: Therrien Jean-David , Vanrolleghem Peter A , Dorea Caetano C
Published: May 2019

Low-cost aerators relying on the venturi principle to entrain air into flowing water have the notable advantage of contributing both to water mixing and oxygen transfer, making them attractive for wastewater treatment in low-resource settings. This study aimed to characterize the performance of such aerators by describing the impact of different design characteristics, including water flow rate, the number of nozzles used, and the nozzle depth. The study also explored the effect on aeration performance of temperature, total dissolved solids (TDS) concentration, and addition of the archetypal surfactant sodium dodecyl sulphate (SDS). Tests were conducted in a 200 L reactor with 2, 3 or 4 nozzles, at depths of 20, 40 or 60 cm, while circulating water through the aeration device at a rate of 400, 600 or 800 L/h. The configuration that yielded the highest mass transfer coefficient (KLa20 of 20.8 h-1) had both the highest flow rate (800 L/h) and the smallest number of nozzles (2). Nozzle depth had no detectable effect on performance. The configuration with the highest standard aeration efficiency (SAE) had a low flow rate (400 L/h) and 4 nozzles. The effect of TDS concentration was not detected in the concentration range typical of domestic wastewater (300–1 250 mg/L). The effect of temperature on KLa followed a first-order exponential curve, as reported in the literature (θ = 1.02). Addition of SDS was found to increase the KLa20 of the tested aerator design by up to 60% of its value in tap water, in contrast to results from literature. The performance data obtained herein was compared to other types of aerators. Though venturi nozzles were found to be less efficient than other available technologies, it is proposed that using plunging rather than immersed venturi nozzles could increase performance to an attractive level for low-resource applications.

Authors: Kopij Grzegorz , Paxton Mark
Published: May 2019

There are few African studies on seasonal changes in the waterbird assemblages in river ecosystems. Tropical freshwater ecosystems are regarded as more stable habitats over the year than terrestrial ones. The same could be expected in regard to the bird fauna associated with such ecosystems. In order to test if waterbird asembalges followed the stable ecosystem paradigm a study was undertaken in the Okavango River, in the Mahango Game Reserve, north-eastern Namibia. Counts of all waterbirds were conducted in wet and dry seasons during 2001–2006. In total, 88 waterbird species were recorded. In wet seasons the number was slightly lower (N = 75) than in dry seasons (N = 78) (chi-square test: χ2 = 0.06; p > 0.05). The total number of individuals of all resident species recorded in wet seasons was unexpectedly much lower in wet (N = 9 979) than in dry seasons (N = 15 501) (chi-square test: χ2 = 1 196; p < 0.01). In wet seasons, Collared Pratincole, Blacksmith Lapwing, African Openbill Stork and African Darter dominated (58.8%), while in the dry season: White-faced Duck, Spur-winged Goose, African Skimmer, African Reed Cormorant, African Darter and Squacco Heron contributed 60.8% to the overall abundance. Diversity indices were similar in both seasons.

Diurnal variation and size dependence of the hygroscopicity of organic aerosol at a forest site in Wakayama, Japan: their relationship to CCN concentrations
Authors: Deng Yange , Yai Hikari , Fujinari Hiroaki , Kawana Kaori , Nakayama Tomoki , Mochida Michihiro
Published: May 2019

Abstract. Formation of biogenic secondary organic aerosol (BSOA)
and its subsequent evolution can modify the hygroscopicity of the organic
aerosol component (OA) in the forest atmosphere, and affect the
concentrations of cloud condensation nuclei (CCN) there. In this study,
size-resolved aerosol hygroscopic growth at 85 % relative humidity and
size-resolved aerosol composition were measured using a hygroscopic tandem
differential mobility analyzer and an aerosol mass spectrometer,
respectively, at a forest site in Wakayama, Japan, in August and September
2015. The hygroscopicity parameter of OA (κorg) presented daily
minima in the afternoon hours, and it also showed an increase with the increase in particle dry diameter. The magnitudes of the diurnal variations in
κorg for particles with dry diameters of 100 and 300 nm were on
average 0.091 and 0.096, respectively, and the difference in κorg between particles with dry diameters of 100 and 300 nm was on
average 0.056. The relative contributions of the estimated fresh BSOA and
regional OA to total OA could explain 40 % of the observed diurnal
variations and size dependence of κorg. The hygroscopicity
parameter of fresh BSOA was estimated to range from 0.089 to 0.12 for
particles with dry diameters from 100 to 300 nm. Compared with the use of
time- and size-resolved κorg, the use of time- and
size-averaged κorg leads to under- and over-estimation of the
fractional contribution of OA to CCN number concentrations in the range from
−5.0 % to 26 %. This indicates that the diurnal variations and
size dependence of κorg strongly affect the overall
contribution of OA to CCN concentrations. The fractional contribution of
fresh BSOA to CCN number concentrations could reach 0.28 during the period
of intensive BSOA formation. The aging of the fresh BSOA, if it occurs,
increases the estimated contribution of BSOA to CCN number concentrations by
52 %–84 %.
LESSON LEARNED ON MONITORING CULTURAL HERITAGE AT RISK UNDER CLIMATE CHANGES: STRATEGY, TECHNIQUES AND RESULTS
Authors: Rosina E. , Romoli E. , Pili A. , Suma M.
Published: May 2019

Abstract. Rising damp is a recurrent cause of damage, and the climatic changes are going towards the increase of humidity (quantity and spreading distribution) in the historic masonry: at 40/50° latitudes, at continental/Mediterranean climatic conditions, the alternance of dry seasons and almost monsoon seasons dramatically affects the distribution of rising damp in porous materials, as well as the water content. Monitoring the presence and distribution of the water is useful to support the choice of the most appropriate intervention, reducing the risk to apply not effective and expensive products and preventing an oversize intervention.The evaluation of the increase of rising damp is a critical issue for preventing the damages, because the presence of the water can sharply, naturally decrease in the dry seasons, as well as rapidly increases one month or more after the beginning of heavy and constant rain.The study cases will show the interaction between climate changes and the inadequacy of the present plant for collecting and drain rain in archaeological areas and historic buildings and as well as the nearby infrastructures that should prevent stagnant rain close to the bottom of the masonry.
ARISTOTLE’S MIRROR: COMBINING DIGITAL AND MATERIAL CULTURE
Authors: Rossi C.
Published: May 2019

Abstract. This article focuses on the relationship between digital and material culture, and on the necessity to establish a dialogue between them centred on the needs of the latter, rather than led by the potential of the former. Our understanding of the material culture changes continuously, and the advent of the digital era represents a significant opportunity to improve and increase our knowledge. The application of modern technologies can only be implemented thanks to a strict collaboration between experts of digital and material culture, as the two points of view can offer fresh insights to one another. It is important to stress, however, that the application of modern technologies should be implemented in order to answer specific research questions, inspired by a precise underlying philosophy, and not simply by which technology is currently available and applicable.

Authors: Shults R. , Bilous M. , Kovtun V.
Published: May 2019

Abstract. The Kyiv Pechersk Lavra is a unique monastery complex included in the UNESCO World Heritage List. The first mentions of the caves in the chronicles date back to the year 1051. The idea of creating a 3D model of Lavra’s caves was suggested by the Kiev Pechersk Lavra coenobites with the aim to attract public attention to the problem of preserving the Lavra Caves for future generations. It consists of an above-ground part (a complex of religious buildings) and an underground part (caves). The caves form a system of underground corridors subdivided into several parts – the Near Caves, the Far Caves, and the Varangian Caves. Today the caves are in an emergency state and need urgent restoration. Results presented in the paper comprise all steps of the 3D model of the Kyiv Pechersk Lavra caves creation. At the first step, a spatial underground geodetic network for scans georeferencing was created. Totally over 60 stations with quite short distances from 2 m up to 15 m, with many open traverses were measured. Terrestrial laser scanning for over than 450 m tunnels and entrance structures has been performed. At the last step, data processing and modelling have been done with a result in the form of plans, cross-sections and TIN model of the whole complex. The paper devoted to features of those works and prospective applications of the results.
CHALLENGING THE INVISIBILITY OF MOBILE CULTURES REMOTE SENSING, ENVIRONMENT AND ARCHAEOLOGY IN THE NEAR EAST
Authors: Silver M. , Törmä M. , Silver K. , Nuñez M. , Okkonen J.
Published: May 2019

Abstract. Remote sensing has provided a modern wider perspective to approach the earth with its various environments and impact of humans by prospecting previously unknown frontiers of human life. The traces of mobile groups are archaeologically often more difficult to detect than those of the sedentary ones, but new approaches and methods have changed and enhanced the ways to extract archaeological information of hunter-gatherers and pastoral nomads. Remote sensing, for example, provides alternative views from above and better visibility in a larger scale, especially with high resolution solutions, than on the ground to trace sites. Mobile people have become more visible in archaeology, and therefore their importance in the development of human cultures has received more focus and understanding. This paper will focus on the use of remote sensing in the archaeological study of mobile cultures and their environments in the Near East. Various examples of techniques and site types will be discussed, and the suitability of applications will be considered based on the studies by Finnish and Finnish-Swedish projects in the Near East. We will provide examples of applications and emphasize the importance of empirical approaches in studying archaeological evidence by remote sensing. GPS coordinate points have served as the basis of our field survey and mapping. From the image-based data we shall deal with aerial photographs, CORONA satellite photographs, Landsat, SPOT, QuickBird and GeoEye satellite images. From the range-based data we shall discuss X-SAR Shuttle Mission 2000 and ASTER-DEM data, but LiDAR and geophysical devices will only be briefly considered.

Authors: Stampouloglou M. , Toska O. , Tapinaki S. , Kontogianni G. , Skamantzari M. , Georgopoulos A.
Published: May 2019

Abstract. Archaeology as a science is based on finding and displaying the remains of the past. In recent years, with the progress of technology, the science of archeology has been expanding and evolving. Three-dimensional digitization has become an integral part of the archiving, documentation and restoration effort of cultural heritage, offering important benefits in studies for reconstruction and restoration tasks of architectural creations, archaeological sites, historic monuments and objects of art in general. The three-dimensional models are now available for many applications. In this paper such 3D models of two prominent Macedonian tombs in Northern Greece were exploited for their virtual restoration. Virtual restoration of monuments is of special importance to archaeological research, as it provides the necessary tools to investigate alternative solutions to the serious issue of archaeological restoration. These solutions do not interfere with the real monument, thus respecting its value and the international conventions. Digital 3D models have begun to be more beneficial in a science such as archaeology as they offer easy access to both archaeological and geometric information to a wider audience as well as a high degree of interaction possibilities with the user.
GEOMETRIC PRIMITIVES ASSESSING ITALIAN-CZECH VAULT CONSTRUCTION TECHNIQUES IN BAROQUE PERIOD
Authors: Stanga C. , Hasníková H. , Brumana R. , Grimoldi A. , Banfi F.
Published: May 2019

Abstract. The developments of the latest technology in the field of Digital Cultural Heritage (DCH) are revolutionizing the methods of surveying, representing and managing the built heritage. The integrated use of 3D survey instruments such as laser scanning, digital photogrammetry and the new holistic way to represent the architecture, based on the Building Information Modeling (BIM), allows the collection, analysis and archiving of a large amount of data, by increasing information sharing among a great number of experts involved during the life cycle of the building. The paper focuses on the connection between Italy and Czech in terms of vaults patterns and construction techniques. The two case studies are the frame vault of the chapel of the Italian Cultural Institute and the barrel vault with lunettes of the Klementinum Baroque Library. They are both unique examples of the great expertise of architects and craftsmen that worked in Bohemia across the 17th and 18th centuries. Most of them were from the North of Italy, like the ones that worked in the building sites of the two case studies. The in-depth study of the construction techniques and the complex shapes needs the use of new scan-to-BIM modeling requirements, based on the definition of geometric primitives useful for the generation of intelligent three-dimensional models able to integrate different types of data. Finally, the acquired data are included in a database that collects information coming from both Italian and Czech studies, raising awareness among citizens of the richness of their built heritage.

Published: May 2019

Abstract. This paper presents the survey of the Baptistery of the Collegiata Museum (Castiglione Olona - Italy), painted by Masolino da Panicale in 1435. Surveying activity was carries out throughout the use of combined digital techniques of documentation (topographic measurements, laser scanning, digital photogrammetry, thermal imaging, digital photography). Different data were collected inside and outside the Baptistery following a multi-resolution reconstruction that ranges from the whole Baptistery up to small details. Laser scans were also used to obtain a digital representation of inner volumes of the structure. Registered scans were uploaded into a modelling software, in order to produce a 3D model based on scan data, increasing the correspondence with the existent building; this model can be used to better understand the volume arrangement, also for educational and dissemination purposes. A particular attention was devoted to documentation of graffiti scratched onto the frescos, since their presence is a significative evidence of the history of the building. A digital-based workflow was set out in order to assure high quality outputs in respect of the conservation needs.This multi-resolution approach proved to be a suitable solution when dealing with features, such as ancient architectures, with a high number of complex details to be correctly recorded and joint together as starting point and support of historical researches. Results and scope are here presented.

Abstract. In the last decade, in the field of conservation of historic buildings, several research projects have shown the potential of applying BIM technology to architectural heritage. However, the use of BIM for historic buildings (HBIM) is still evolving. This paper presents an application of Building Information Modelling targeted to the development of a restauration proposal for the ex-church of San Quirico all’Olivo in Lucca, Tuscany. Following a brief review of the state-of-the-art of BIM applied to architectural heritage, the paper shows the results of a study that included 3D architectural survey with Structure-from-Motion methodology, critical analysis of historical archival and bibliographic sources, analysis of the conservation status of the building, proposal for its conservation and enhancement.HBIM methodology has been critically applied to all the phases of the project. This study also explores the possibility of organizing the BIM model into temporal phases, integrating documentation in a structured and easily accessible way. In our study, we also chose to link the 3D point cloud to the model, in order to increase the level of information; the 3D survey, therefore, is both the starting point for modelling, and represents a source of information within the model, to be recalled when required.

Abstract. Relevant cultural heritage buildings have been subject to numerous maintenance interventions over the years. Building Information Modelling (BIM) technology is already part of the construction industry especially in the design phase and is considered as a very useful tool. From a survey with an Unmanned Aerial Vehicles (UAVs), using photogrammetry is possible to determine characteristics such as sizes and shape object, volumes, areas, distances, elevations and furthermore the reconstruction of high-quality model. A whole integration between the two methods will be a “game changer” for the construction sector. Moreover, old buildings have complex architecture, with high and particular details that today's BIM software’s aren’t able to perfectly represent today.In this paper, we present a methodology to integrate into BIM environment a 3D reconstruction as-built drawings of an old church using photogrammetric techniques, in order to find a solution to reproduce the complex details present in ancient buildings.

Published: May 2019

Abstract. In Qajar period, the era of the formation of urban fabric along with a rooted tradition close to the contemporary architectural era of Iran, specific motifs and decorative patterns were formed on the buildings, including flowerpots with scattered flowers that developed on all constructions of this era (the mosques, schools, palaces, and mansions), which were applied with assorted materials especially seven-color tiles.The present study was a descriptive-analytic research conducted referring to reliable library resources, and visual and electronic documents, and, it was intended to answer the following question: What is the origin of scattered flowers with spiral stalks issuing from realistic and abstract flowerpots?Findings show that the origin of scattered flowers with symbolic meanings of life, growth and immortality is the earthenware found in Sialk, Kashan, which were common in ancient era and after Islam, they became widespread with the same content and theme as arabesque forms. Then, they were recreated in Qajar Era and by being originated from realistic and sometimes abstract flowerpots, they were depicted on the buildings with symmetric spiral arabesque forms.
HOLISTIC HERITAGE BUILDING INFORMATION MODELLING (HHBIM): FROM NODES TO HUB NETWORKING, VOCABULARIES AND REPOSITORIES

Published: May 2019

Abstract. HBIM (Heritage Building Information Modelling) can be nowadays considered as part of the digitization process of Cultural Heritage, with the particular characteristics that being born to manage Models and Data within a unique environment they can be inherited to adopt a synergic approach to the cultural Heritage ‘as a whole system’. To this aim they need to overcome gaps and barriers undertaking an holistic approach in many directions. The paper intends to introduce an overview on the meaning of Holistic Heritage Information Building. The attribute holistic is here used with the meaning to empower instruments and methods capable to interconnect single HBIM nodes within networks where to find the information collected in a cross sectorial space: vocabularies, libraries of object and semantics, derived from such ‘Informative Models’ - with the support of Virtual Hub technologies - can boost nodes-networking empowering the capabilities of BIM Informative Modelling together with web accessible Geographic Informative System. Such richness once interconnected can be accessed from space-temporal queries, semantic searches, and harvested with other networks in order to enhance the cross correlation of the information and allowing the sharing of different case studies and HBIM within a space-temporal framework. This will allow the comparison of masonry texture, history of material finishing and skilled workers across space and time. HHBIM HUBS will be a gate toward the eXtended Reality potentials attracting and distributing data coming from different sources.
DIGITAL STORAGE AND THE DATA COLLECTION FOR THE SEISMIC PREVENTION: A COMPARISON FROM THE ITALIAN RECENT EXPERIENCES
Authors: Brusa E.
Published: May 2019

Abstract. Concerning the care of our Built Heritage, one of the most important problem that was observed after an earthquake is the speed in the reaction, aiming to minimize the damages provoked by the shakes. As a matter of fact, the necessary time for the reaction of the rescue teams should be not too long, in order to avoid further damages provoked by the future shakes. Thus, the best way to minimize this type of damage is to design appropriate shoring systems that replace the lack of stiffness provoked by earthquake as soon as possible. In this sense, it’s necessary to know many information of a damaged monument, such as: the geometry, the materials and the structural characteristics, the presence of previous alterations and/or restorations, etc. Unfortunately, the accessibility to this kind of information is not always available after an earthquake, due to the possible damages provoked to the buildings, where the public archives and the documentation are normally stored (L’Aquila 2009, Amatrice 2016).The awareness of this problem started immediately after the serious earthquake that hit the city of L’Aquila in 2009. Then, it became more urgent after 2016, when the extended and continued earthquake in the Centre of Italy provoked increasing damages to buildings and monuments. In particular, an important role in the churches’ collapses that had occurred during this last earthquake was due to the difficulty in finding the necessary information to design proper shoring systems.Nowadays, starting from the experience of L’Aquila, teams composed by functionaries of the Ministry of Culture, engineers from different universities and special members of the Fire Brigade have developed and improved various models for the management of the emergency phases. Using the modern geomatics tools (i.e. Unmanned Aerial Systems (UAS), Terrestrial Laser Scanners (TLS), Remotely Piloted Aircraft Systems (RPAS)), it’s possible to achieve the digital acquisition of many building’s data and characteristics (i.e. through the 3D Object recognition and reconstruction, the point cloud analysis, etc.).This article examines some of the most interesting solutions that were adopted after the recent Italian earthquakes (L’Aquila 2009, Emilia-Lombardia 2012, Centre of Italy 2016) by some of the major public Entities (Superintendences, Italian Fire Brigade). Moreover, it evaluates the possibility to enhance both the competences and the tools that have been until now developed, with the purpose to use them for an effective Built Heritage prevention, without having to wait a new emergency phase to adopt them.
THE “CARA VALLE” ABBEY AND ITS REFECTORY
Authors: Guarisco G. , Oreni D.
Published: May 2019

Abstract. The Refectory of Chiaravalle abbey, still in use today, is a masonry building (with bricks that are not common in size), vaulted and characterized by complex stratifications that required careful cognitive analysis of the documentary sources, structural and physical analysis to be understood. To this aim, an accurate 3D laser scanner and photogrammetric survey was carried out during last years in order to obtain geometric information on the building and its complex elements, in scale 1 : 50. Those data were also fundamental to support the mapping of the different construction phases, the transformations and the dated additions, to be compared to the archive, iconographic and photographic documents. A canal derived from the Vettabbia, which served to move the blades of the mill (now reactivated), flows right under the Refectory causing the usual phenomena of degradation. Saint Bernard had chosen this place because it was rich both in water, and therefore highly productive, and in clayey soil, which allowed the construction of the buildings of the abbey. However, today the strongly compromised irrigation and water regulation system (especially after the construction, in 2003, of the large purifier in Milano Nosedo) represents the main factor of degradation for all the buildings of the monastic complex, in particular for the Refectory.The purpose of this paper is to present the main results of the studies and surveys conducted on the Chiaravalle abbey in the last ten years, focusing in particular on the Refectory.

Abstract. Such innovative meeting dedicated to Cultural Heritage: challenges, new perspectives, and technological innovation are ‘vital’ in order to exchange different experiences, needs, opportunities, and, above all, to find new approaches to preserve, at least, the memory of heritage for further generations. This paper includes some experiences accumulated throughout several topographic projects concerning Christianity during the Late Antiquity and Early Medieval Ages in northern Syria, in Liguria in Italy, and in Provence in France. Geospatial and Geomatics data have been used in these investigations, since 2007, thanks to the Pontifical Institute of Christian Archaeology of Rome, the National Institute for Art History in Paris, Nino Lamboglia Foundation, and Marc de Montalembert Foundation. The Geospatial data highlighted for the first time, after about a century of research, much un- published data about Syrian monasteries. One of our goals was to understand what the exact differences are from all points of view: time, results, and economic costs between Agisoft Photoscan and MicMac. The models of the two applications are well made, but we noticed that the model created by MicMac software is excellent, despite being an open source application. In 2017, due to the positive geomathic results during the last three seasons of our excavations on the site of Capo Don, the first Multimedial Exhibition Space (SEM) of the town Riva Ligure was inaugurated, thanks to Comune of Riva Ligure, and all research team members guided by professor Philippe Pergola. Geomatics is a powerful tool not only for preserving memories, but it is ideal for dissemination heritage on the public levels, exactly like the role of archaeology.
INTERPRETATION OF THE FUNCTION OF THE OBELISK OF AUGUSTUS IN ROME FROM ANTIQUE TEXTS TO PRESENT TIME VIRTUAL RECONSTRUCTION
Authors: Hiermanseder M.
Published: May 2019

Abstract. About the astronomical use of the obelisk of Augustus on Campo Marzio in Rome, which has already been described by Pliny, well known astronomers and mathematicians like Euler, Marinoni or Poleni have given their expert opinion immediately after it's unearthing in 1748. With the prevailing opinion, based on a brief chapter in "Historia naturalis", it would constitute a line of meridian rather than a sundial, the question had been decided for more than 200 years.In 1976, however, the prominent German archeologist Edmund Buchner established once more the assumption, that the obelisk has been part of a gigantic sundial for the apotheosis of the emperor Augustus. Excavations of the German Archeological Institute in 1980/81, which brought to light parts of the inscriptions of the scale, were taken as a proof of his theory by Buchner.Since 1990 works by physicists and experts for chronometry like Schütz, Maes, Auber, et.al., established the interpretation as a line of meridian. Recent measurements and virtual reconstructions of the antique situation in 2013 provide valid evidence for this argument as well.The different approach to the problem mirrors the antagonism between interpretation of antique texts and the assessment of archeological findings in the light of far fledged historical hypotheses.

Published: May 2019

Abstract. This paper discusses the relationship between advanced geomatics and Conservation Management Plan (CMP), by deepening the case of a CMP dedicated to the conservation of the 20th century architectural heritage. A number of issues have already been discussed on how the advanced survey techniques contribute to the conservation field for the last decades (e.g. Laser Scanner, HDR, GIS, intelligence vs. abundance, B.I.M, VT/IM etc.). The authors analyse pros and cons of each technique with respect to the main purposes of a CMP: 1.knowledge, 2.value assessment, 3.data sharing and dissemination of results, 4.support for conservation and restoration activities, 5.support for the planned conservation of buildings / facility management over time. With respect to the research on the CMP for the National Art Schools of Havana, the conclusions focus on the need to share results to non-specialist stakeholders, and on the possibility to combine different scales of analysis and a plurality of buildings with various levels of interest and conservation needs.
BUILDING ASSESSMENT USING SHADOW ANALYSIS FOR THE ARCHITECTURAL DOCUMENTATION
Authors: Kadhim N. , Kadhim N.
Published: May 2019

Abstract. One essential approach in preserving architectural heritage is the documentation of building geometries and their sites are thoroughly photographed of existing buildings. For instance, an automated detection of the locations and the extraction of geometry information of the buildings are intrinsic attributes of the architectural design of building interiors and exteriors in cultural heritage documentation and preservation. In this study, contributions of remotely sensed images to detect the sites and shapes of the buildings based on shadow analysis were evaluated. The aim of this paper is to develop an approach to assist in recording and documenting the external geometry of historic buildings and their real location supplying much ease and time-saving in protection projects of cultural heritage. A distinctive merit of the proposed approach is its ability to document the spatial distribution of the detecting buildings by extracting the graphic coordinates of their corners without any additional data. Our experiments demonstrate the efficiency of the proposed approach on two cases, including the architectural documentation of external edges, shape, size, site, orientation, and coordinates. Thus, our new approach offers a tool to document architectural and cultural heritage which can help in capturing and recording all the relevant data and information, both in visual and written format.
SUSTAINABLE LAND USE EVALUATION BASED ON PRESERVATIVE APPROACH

Abstract. Determining the manner of land-use and the spatial structure of cities on the one hand, and the economic value of each piece of land on the other hand, land-use planning is always considered as the main part of urban planning. In this regard, emphasizing the efficient use of land, the sustainable development approach has presented a new perspective on urban planning and consequently on its most important pillar, i.e. land-use planning. In order to evaluate urban land-use, it has been attempted in this paper to select the most significant indicators affecting urban land-use and matching sustainable development indicators. Due to the significance of preserving ancient monuments and the surroundings as one of the main pillars of achieving sustainability, in this research, sustainability indicators have been selected emphasizing the preservation of ancient monuments and historical observance of the city of Susa as one of the historical cities of Iran. It has also been attempted to integrate these criteria with other land-use sustainability indicators. For this purpose, Kernel Density Estimation (KDE) and the AHP model have been used for providing maps displaying spatial density and combining layers as well as providing final maps respectively. Moreover, the rating of sustainability will be studied in different districts of the city of Shush so as to evaluate the status of land sustainability in different parts of the city. The results of the study show that different neighborhoods of Shush do not have the same sustainability in land-use such that neighborhoods located in the eastern half of the city, i.e. the new neighborhoods, have a higher sustainability than those of the western half. It seems that the allocation of a high percentage of these areas to arid lands and historical areas is one of the main reasons for their sustainability.

Abstract. In September 2018, photogrammetric images and terrestrial laser scans were carried out as part of a measurement campaign for the three-dimensional recording of several historic churches in Tbilisi (Georgia). The aim was the complete spatial reconstruction with a spatial resolution and accuracy of approx. 1cm under partly difficult external conditions, which required the use of different measurement techniques.The local measurement data were collected by two laser scanning campaigns (Leica BLK360 and Faro Focus 3D X330), two UAV flights and two terrestrial image sets. The photogrammetric point clouds were calculated with the SfM programs AgiSoft PhotoScan and RealityCapture taking into account the control points from the Faro laser scan. The mean residual errors from the registrations or photogrammetric evaluations are 4-12mm, depending on the selected software. The best completeness and quality of the resulting 3D model was achieved by using laserscan data and images simultaneously.

Published: May 2019

Abstract. On May 20, 2012, an earthquake of magnitude ML = 5.9 hit a vast area of the Po Valley, in the territory across Lombardia, Veneto and Emilia, with the epicentre close to Finale Emilia. The seismic event, unusually intense for the area, caused extensive damage to the built heritage, so that six years later many buildings are still waiting for the necessary restoration works. One of them is the Villa Galvagnina in Moglia, in the province of Mantua.The damages caused by the earthquake made necessary emergency strengthening works. Alongside these emergency measures, the Local Office of the Ministry of Culture considered suitable to start more detailed studies on this neglected asset.The present study is part of the Superintendence initiatives, concerning the mapping of the building materials, a survey about murals’ decay, as well as the damage and crack patterns. The aim of this data acquisition campaign is to identify the main risk factors for the preservation of the villa and to identify possible strategies for the strengthening and conservation works. The article critically presents the working method adopted for the survey setting up. The data acquisition steps, the difficulties experienced, and the choices made are fully described and some preliminary considerations are also expressed on the main damage suffered by the villa and on the ongoing deterioration.
