In this paper, the variable-modulus elastoplastic strength reduction method (SRM) is used to obtain the stress field, displacement field, and factor of safety of slope. Slope reinforcement using anchor cables is modeled by surface loading, i.e. different distributions of surface loading represent various reinforcement schemes. Optimal reinforcement scheme of anchor cables can be determined based on slope stress and displacement fields. By comparing the factor of safety and stress field before and after slope reinforcement, it is found that better reinforcement results can be achieved if strong reinforcement is applied upon the regions with high stress and large displacement. This method can well optimize the arrangement of anchor cables. In addition, several cases are employed to verify the proposed method.

An important limitation in the past was the lack of technologies and materials that could replicate an object like this in detail. Only a few years ago technology was not yet able to ensure accurate reconstruction characterized by an adequate formal aesthetic level both in terms of materials and finishes. Nowadays, this gap has been filled thanks to the development of Computer Numerical Control machines (CNC) in production processes. In this contribution, we present part of the restoration of Villino Florio in Palermo, built by the architect Ernesto Basile on behalf of the Florio family between 1899 and 1902 and partially destroyed by a fire in 1962: it is one of Italy’s first architectural works in the Art Nouveau style, and is considered a masterwork within the European panorama....

Una piena trasparenza dei metodi, delle tecniche e della documentazione a corredo di un progetto di archeologia virtuale è necessaria al fine di definire standard di qualità che innalzino il valore scientifico di una disciplina che promette di informare, stupire e affascinare con sempre maggiore efficacia e rigore. Spesso però la documentazione di base è insufficiente a garantire un livello di attendibilità che possa escludere alternative. In conseguenza di questo si dovrà necessariamente ricorrere a confronti, deduzioni e metodi che permettano di tracciare il processo ricostruttivo in ogni sua parte. Partendo dai risultati di un caso di studio condotto sul sito di Monte Sannace, vengono qui descritti i diversi metodi utilizzati, con l’obiettivo di denunciare il livello di attendibilità della ricostruzione in rapporto a fattori qualitativi non sempre facili da soppesare, ma importanti ai fini del rispetto del Principio N. 7 della Carta di Siviglia, che riguarda la trasparenza delle informazioni e dei metodi usati nella ricostruzione. Si analizzano sul piano teorico le analogie e le differenze con i metodi dei Restauro moderno e si descrivono i risultati conseguiti in rapporto agli obiettivi di progetto, in gran parte proiettati sul piano comunicativo, didattico ed emozionale. La ricostruzione virtuale del sito di Monte Sannace, all’interno del più ampio progetto di recupero e valorizzazione, rappresenta un contributo importante nei processi di conoscenza e comunicazione di un contesto da tempo misconosciuto. La visita del Parco fornisce oggi un’esperienza di sicuro interesse, perché dà la possibilità di riconoscere ed apprezzare, insieme alla componente archeologica, le rilevanti valenze paesaggistiche presenti in questa parte del territorio pugliese.

Reality) applications have opened up multiple paths of knowledge
and visualization. State-of-the-art applications take advantage of
the availability of real-time 3D models characterized by increasing
complexity. At the same time, non-real-time forms of visualization have
evolved, these are mainly based on pre-calculated images with new
functionalities. The versatility of use of these systems of visualization
and reading information allow the development of applications out of
the ordinary schemes, typically for tourism/information use, especially
in the domain of cultural heritage.
This study therefore proposes a reading of information ‘beyond the
visible’ exploiting VR/AR capabilities to observe in an interactive way the
interior of architectural structures of the Church of Convento do Carmo
in Lisbon.

underground oil-mill in the town of Gallipoli (Puglia, Italy). The limitations of access for people with disabilities and the complete closure
of Italian museums during the emergency have suggested the development of an immersive platform, in the broader perspective of
using the output in accordance to digital twin perspectives. Then a tool to support an innovative visit method has been realized: a virtual
visit assisted by a real remote guide, hereinafter referred to as “Live-Guided Tour” with e-learning functionality. All this has been made
possible starting from a three-dimensional model of an underground oil-mill, from which we extracted the stereoscopic scenes. The
stereoscopy is very important for the overall success of the project, because this aspect influences the level of interest, the immersion
and the ability to generate emotion and wonder. To the best of Author’s knowledge, this is the only system available today for a shared
virtual visit for an inaccessible context, which implements many features of a VR visit in a multi-user and multi-platform environment.

The fortified medieval settlement of Rocca Montis Dragonis (Mondragone, Caserta – Italy) virtually alive

From 2001 until now, archaeological investigations discovered a big part of the entire settlement, known on written sources from 12th century, which is a big size hilltop site, characterized by a complex group of structures hierarchically distributed in three different areas. The main focus of this work is to produce friendly communication tools, aimed to develop storytelling, by Virtual Reality methods, concerning the results of recent archaeological excavations, and in particular those aspects from which generates the phenomenon of incastellamento”. The methodology used in this research runs from detailed observations of the artefacts evidence and from the study of low scale settlement dynamics, to the general interpretations concerning the architecture of the Rocca Montis Dragonis and the social and economic aspects referred to the building opera. On what concerns these aspects we could define this method an “inductive” one, from which originates every scientific result. The main targets of this paper have been the use of the huge archive deriving from the archaeological activities, interesting one of the most important medieval castle of northern Campania (Italy), to reconstruct with new technologies the original shape and the life of this settlement. Moreover the application of 3D virtual technology is aimed to the best promotion, knowledge, protection and conservation of this particular item of cultural medieval heritage.

The navigation platform allows the user to visualise complex scenes and DVR-based knowledge models in “full-screen mode” even on desktop computers. As well as showing the current state of the monuments, the visit includes reconstructions of previous phases in their history and virtual restorations of the Byzantine paintings. All the textures were obtained by processes of photomodelling and were applied to the geometrical forms in accordance with the radiosity algorithm, with lights and shadows of the ‘area’ type. The result is extremely life-like, almost indistinguishable from reality.

From museum to original site: A 3d environment for virtual visits to finds re-contextualized in their original setting

In the case of funerary contexts, a consequence of this is the de-contextualization of grave goods and furnishings, making it impossible to convey the significance of the archaeological monument as a whole. An effective solution to this problem can be achieved by using technology to provide virtual experiences in which the grave goods, for example, are virtually restored to their original contexts. This paper presents the “Marta Racconta. Storie Virtuali di Tesori Nascosti” project, co-financed by the Fondazione Cassa di Risparmio di Puglia, undertaken by CNR-IBAM (Lecce, Italy) in order to install a virtual platform in the National Archaeological Museum of Taranto (MARTA). The project aims to make `accessible' ancient monuments from the Greek Taras (the ancient Taranto), such as the Twin Tombs Monumental Complex, the Tomb of the Festoons, and the Hypogeum of the Gorgons, discovered some years ago in Via Otranto. The first two of the these monuments are closed to the public, while the third was filled in and is currently located below a road. From a technological point of view, a real time 3D platform for immersive stereoscopic visiting was developed, with a navigation system using a `natural interface' and commands executed with simple hand gestures. Using this technology, visitors will be able to follow an integrated knowledge itinerary based on heterogeneous content including historical and archaeological data and the results of archaeometric analyses. This involves spatial navigation within a hyper-realistic environment where it will be possible to interact with the 3D structures, to query the database and to interact with

The presence of a coin bearing the head of the emperor Commodus (180-192 AD) among the materials found has made it possible to date the wreck to the end of the II – beginning of the III century AD. The cargo consisted of 18 sarcophagi and 17 blocks, all of white marble, as well as six alabaster slabs. The marbles were attributed by Ward-Perkins (1965) to the quarries of Aphrodisia and by Parker (1992) to the quarries of Thassos. The salvaged materials were taken to Taranto where currently 15 sarcophagi and 14 blocks, all in white marble remain. Each of these has been catalogued with a view to classifying them in metrological and typological terms, and sorting them into homogeneous groups. The metrological study shows that the Roman foot is the most likely unit of measurement. The typological analysis makes it possible to recognise two types of sarcophagus: 1- rectangular sarcophagi with rectangular cavity (six items), 2- rectangular sarcophagi with apse cavity (nine items). The blocks, of rectangular shape, are semi-worked products; some of them were intended for use in construction or as lids for the sarcophagi.
