Diagnosis and methods against rising damp in industrial heritage buildings: a case study in Italy

The presence of water and rising damp in particular is the most relevant cause of decay in historic buildings. Damage processes such as biodeterioration, frost and salt crystallization arise or are intensified in the presence of rising damp and its relevance is expected to increase in the future, due to climate changes. Treatment against rising damp is therefore generally advised for protection and durable conservation of historic buildings. The JPICH Project "Effectiveness of methods against rising damp in buildings: European practice and perspective – EMERISDA" aimed at a scientifically based evaluation of the effectiveness of different methods against rising damp and decision support tool definition for a conscious choice use of these methods in the practice of conservation. During the present contribution, the main results obtained for the case study in Ferrara (Italia) will be discussed. Specifically, the treatments applied and the methodological approach for their effectiveness assessment will be presented.

Mobile app for promoting cultural heritage: geostatistic and textual analysis

This study presents an innovative technological solution, applied to the promotion of both tangible and intangible cultural heritage of the Salento territory (an Italian sub-peninsula). For the itinerant folk music festival called "La Notte della Taranta", in 2015 an official mobile application called FolkTure, was been used by tourist and citizens during the entire period of the itinerant event (August). Through the application of gamification strategy, augmented reality solutions and multimedia contents, FolkTure app facilitated and stimulated the enjoyment of the event itself and encouraged tourists and citizens to visit the Salento cultural heritage mapped inside the app. The data extracted from the mobile FolkTure app was analyses and interprets through an innovative approach. Text analytics techniques, like semantic and sentiment analysis, integrated with spatial analysis techniques, allowed to identify sentiment score spatial variation and locate geographical area characterized by negative or positive average sentiment score, in order to understand the impact of a cultural event on the local territory.

Hazard and Risk Assessment and Perception in the Analysis of Cultural Heritage

The concept of "risk" and how its meaning is related to that of other concepts such as "danger", "hazard", "safety" and "uncertainty" has been studied for almost a century. When risk is involved, human decisions are conditioned by the different perception and elaboration of the relevant information connected to the choice process. For example, positive and negative feedback about past risk taking can affect future risk taking. People who are led to believe they are very competent at decision making see more opportunities in a risky choice and take more risks, while those led to believe they are not very competent see more threats and take fewer risks. During the preparation of an experiment on samples of cultural relevance, a deeper awareness of these concepts should be taken into consideration, as well as an informed knowledge of the mechanisms of decision making in presence of a possible damage.

Business Process Management and Building Information Modeling for the innovation of cultural heritage restoration process

Cultural heritage is a complex ecosystem requiring innovative methods and techniques to facilitate its management and valorization. In detail, restoration processes have to preserve the original characteristics of historical buildings or sites, by involving different professional figures, each one with different roles, responsibilities and skills. In this light, a system that facilitates the information management, supported by new technologies, could allow more precise, efficient and traceable information exchange and could optimize the construction and management operative phase. Starting from these assumptions, this research proposes the application of a new integrated approach to a restoration process of a historical building. It consists in applying BPM technique and BIM methodology to provide valuable insights to optimize the data flow, to gather information and to share knowledge during the restoration process through the lifecycle management, by facilitating the ordinary and extraordinary maintenance, really essential for the Italian heritage.

ICV and fine-registration algorithms for an efficient merging of point clouds

One of most important and frequents needs that arise when we have to handle the point clouds is to merging them in an efficient and precise manner so that we can obtain more complex and bigger 3D models by chunks, seamlessly. ICV, Intelligent Cloud Viewer, is a software developed in-house by AESEI (spin-off of Polytechnic of Bari) that contains many tools and filters for point cloud processing. In this paper we illustrate the fine-registration algorithm implemented in ICV, one of the countless variants of ICP methods (Iterative Closets Points). The fine-registration method can be usefully adopted to estimate the differences between point clouds of the same subject executed in different times or for a comparison of point clouds of same subject obtained with different acquisition techniques, for example a laser-scanner and a photogrammetric technique. Furthermore, ICV integrates the M3C2 module for a robust error analysis, where by error is intended the differences or distances between similar point clouds.

WebGIS, 3D modeling and virtual tours to map, record and visualize the cultural, archaeological and landscape heritage: the VisualVersilia project

This article describes the methodologies and technologies developed during the realization of the WebGIS (Geographic Information System) visualversilia.com, namely a multimedia guide able to map, survey, visualize the rich cultural, archaeological and landscape heritage of Versilia (northwestern Tuscany). It enables users to delve into different temporal settings and to contextualize the local cultural sites within the geographic space of their specific historical periods. The immersive experience is also achieved thanks to the realization of virtual tours and navigable 3D models of archaeological complexes concerning the past and current appearance. This WebGIS is a digital platform, soon available online, for viewing and managing data relative to the cultural sites of Versilia, through their localization on an interactive map with several thematic layers, divided into chronological sub-layers. The aim of the research project is to provide useful information for knowledge, protection and enhancement of the cultural heritage of the area.

Multi-wavelengths3D laser scanner for investigation and reconstruction of 19th century charcoal inscriptions

Digital reconstruction is nowadays a widespread practise and, at the same time, a useful tool in CH field, starting from the study of works of art up to the delineation of conservation actions. The present work describes the use of the ENEA 3D laser scanner prototype, called RGB-ITR, for a deepen investigation of 19th century charcoal inscriptions on wall drawings, placed in the Saint Sebastian Door of the monumental Aurelian Walls (Rome), with the aim of understanding the historical value. The results of post-processing analysis of the high detailed 3D models with properly-developed algorithms allowed the preliminary reconstruction of the contents, demonstrating the value of the adopted technique for 3D digitalization of the room thanks to its features, such as independence from variable lighting conditions, acquisitions at great distances and no need of area interdiction or scaffolds.

Experimental methodology for measuring the structural dynamic transmission damping of a cultural heritage tower

This paper presents the dynamic experimental campaign carried out on simple model related to a stocky masonry clock tower situated in the Swabian Castle of Trani (Italy). The main objective of this paper is, after estimating the main frequencies and vibration modes of the considered structure, defining the influence on the structural damping dynamic transmission of the frequency of excitement. At this aim, firstly, an accelerations' record has been acquired simultaneously in 23 points of the tower at different levels, both due to environmental vibrations and to a series of sinusoidal forced vibrations applied at the base by using a pneumatic shaker device specify designed for the tests.

Ancient Monuments Analysis by Motion Magnification

A new methodology for digital image processing, namely the Motion Magnification, allows to magnify small displacements of large structures. Motion magnification acts like a microscope for motion in video sequences, but affecting only some groups of pixels. The processed videos unveil motions hardly visible with the naked eye. We apply the motion magnification to a scale mockup of the Hagia Irene church stressed by a shaking table, to the socalled Temple of Minerva Medica in Rome and to the Ponte delle Torri of Spoleto. Results are surprising, offering a low-cost, viable support to the standard equipment such as contact accelerometers, laser vibrometers, linear variable differential transformers.
