An Overview of Geophysical Techniques and Their Potential Suitability for Archaeological Studies
2023
The need to study, protect, and conserve archaeological heritage has enhanced the application of geophysical techniques as non-invasive and reliable tools to investigate fragile and valuable assets. This review presents the most popular geophysical techniques suitable for archaeogeophysical investigations, namely, magnetometry, ground penetrating radar, and electrical resistivity tomography, together with a series of multiparametric measures taken from aerial platforms (UAS). For each method, we recall the basic physical principles, illustrate the operative procedures for field investigation, and provide indications about data processing and modeling. We propose a flowchart to address relia…
Biological mineral content in Iberian skeletal cremains for control of diagenetic factors employing multivariate statistics
2013
Abstract The aim of this study was to define a strategy for a correct selection of bone samples by employing inductively coupled plasma optical emission spectroscopy (ICP-OES) for reconstructing the biological mineral content in bones through the determination of major elements, trace elements and Rare Earth Elements (REE, lanthanides) in skeletal cremains of ancient Iberians (III–II B.C), discovered in the Necropolis of Corral de Saus (Moixent, Valencia) between 1972 and 1979. The biological mineral content was determined taking into account diagenetic factors. A control method for a better reading of results was applied. To explore large geochemical datasets and to reduce the number of va…
The Purpose and Age of Underwater Walls in the Bay of Elaia of Western Turkey: A Multidisciplinary Approach
2014
Pergamum (modern: Bergama) was operating an important harbour used by military forces and merchants at the city of Elaia during Hellenistic and Roman Imperial times. Harbour-related facilities such as warehouses, breakwaters and wharfs document the importance of this harbour site not only for the Pergamenians. This paper focuses on the purpose and age of six submerged wall structures situated approximately 1 km south of the ancient closed harbour basin of Elaia. Geoelectric cross-sections and semi-aquatic coring near these walls failed to detect any solid basement under the walls which excludes their possible use as breakwaters or wharfs. Instead, the walls were most likely delineating and …
A detailed method for creating digital 3D models of human crania: an example of close‑range photogrammetry based on the use of Structure‑from‑Motion …
2022
AbstractPhotogrammetry is a survey technique that allows for the building of three-dimensional (3D) models from digitized output data. In recent years, it has been confirmed as one of the best techniques to build 3D models widely used in several fields such as life and earth sciences, medicine, architecture, topography, archaeology, crime scene investigation, cinematography, and engineering. Close-range photogrammetry, in particular, has several applications in osteological studies allowing to create databases of 3D bone models available for subsequent qualitative and quantitative studies. This work provides a step-by-step guide of the photo acquisition protocol and the photogrammetric work…
The Vuelo Ruiz de Alda (1929-30): an exceptional cartographic document. Again about Ilici
2015
Se presenta en este artículo una primera valoración de las posibilidades que para la arqueología, y más concretamente para la estratigrafía del paisaje, encierra un soberbio documento como es la serie fotográfica conocida como Vuelo Ruiz de Alda (1929-30), una vez que los fotogramas han sido ampliamente puestos al alcance de la investigación. Para ello se ponen a prueba las imágenes aplicándolas a dos establecimientos de época ibérica antigua (El Oral y El Molar). Igualmente, se ha retomado una línea de investigación a propósito de la red caminera que afecta al enclave de La Alcudia-Ilici, lo que lleva implícitamente a tratar sobre su catastro romano y la trama parcelaria de todo su entorno…
Terrestrial laser scanning and close range photogrammetry for 3D archaeological documentation: the Upper Palaeolithic Cave of Parpalló as a case study
2010
Graphic and metric archaeological documentation is an activity that requires the capture of information from different sources, accurate processing and comprehensive analysis. If monitoring of the state of conservation is required, this task has to be performed before intervention, during and after the completion of the works in a repetitive way. This paper presents the use of terrestrial laser scanning (TLS) in order to effectively produce, prior to intervention, accurate and high-resolution 3D models of a cave with engravings dating back to the Upper Palaeolithic era. The processing of the TLS data is discussed in detail in order to create digital surface models. The complexity of the cav…
From Historical Silk Fabrics to Their Interactive Virtual Representation and 3D Printing
2020
The documentation, dissemination, and enhancement of Cultural Heritage is of great relevance. To that end, technological tools and interactive solutions (e.g., 3D models) have become increasingly popular. Historical silk fabrics are nearly flat objects, very fragile and with complex internal geometries, related to different weaving techniques and types of yarns. These characteristics make it difficult to properly document them, at the yarn level, with current technologies. In this paper, we bring a new methodology to virtually represent such heritage and produce 3D printouts, also making it highly interactive through the tool Virtual Loom. Our work involves sustainability from different per…
The virtual reconstruction of the minaret of Mansourah mosque (Algeria)
2015
This contribution synthetically addresses some of the photogrammetric solutions available today in the field of architectural-archaeological survey and the related applications outcome, evaluated during both the acquisition phase of metric data than in those of effective yield of refunds infographics. Therefore, we have focused on the virtual reconstruction of one of the most emblematic and symbolic building of the Algerian culture, the mosque of Mansourah, returning the minaret as it appeared before its partial collapse, namely correspondent in geometry, textures, and colours. The work is part of a larger research project to promote knowledge and dissemination of Algeria cultural heritage,…
Agent-Oriented Captology for Anthropocentric Systems
2001
Abstract Considering that anthropo centric systems are an adequate domain for captological approaches, and that interface agents are most natural interactants for the humans involved, the paper presents a broad-spectrum generic architectural framework to support developing flexible interfaces for industrial applications, based on synergetic correlation between persuasive technologies and polymorphic agents. The design space for agent-oriented captology is defined and several of its main dimensions are elaborated upon. The main mechanisms used are dynamic priorities, "flexible cloning" and fuzzy temporal windows. Some agent-oriented test-bench applications instantiating the generic architect…
Una committenza nobile in Sicilia tra Cinque e Seicento. Le architetture dei Branciforte di Raccuja (1552-1661)
2014
Oggetto di studio della tesi sono i programmi costruttivi avviati tra il Cinque e il Seicento dal casato dei Branciforte di Raccuja. In particolare la tesi affronta lo studio delle architetture fondate da Nicolò Placido Branciforte nel corso del Seicento: il palazzo di famiglia a Palermo e il castello di Leonforte. I programmi costruttivi sono stati analizzati in relazione al cursus honorum, alla politica economica e culturale del casato e posti a confronto con gli omologhi interventi edificatori intrapresi da pari e sodali, secondo una metodologia conoscitiva auspicata da studi precedenti e non ancora messa in atto in Sicilia. In this thesis we study the architectural programs initiated by…
