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…
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,…
The Averinga’s Edicola and the Cult of Water in Palermo. From Knowledge to Valorisation
2018
Si descrive un approccio multidisciplinare allo studio di un singolare monumento storico, l’Edicola dell’Averinga, che versa attualmente in gravi condizioni di degrado; questa costruzione fu realizzata nel 1587 dal Senato Palermitano a protezione delle acque della sorgente Ayn Rutah (nome arabo di Averinga) che sgorgavano proprio al suo interno e che da qui venivano raccolte e incanalate verso i fertili giardini, le abitazioni che si trovavano in prossimità delle mura cittadine e alcune delle più importanti fontane della città storica. La più antica descrizione a noi pervenuta della zona in cui è sita l'Edicola, la cosiddetta depressione Danisinni, appartiene al geografo iracheno Al-Qaim Mu…
Vincenzo Vincenzi, “Geometer and Engineer to Cardinal Borja”
2017
This paper analyses the figure of Vincenzo Vincenzi on the basis of documents that place him in Valencia in 1635 as engineer and geometer to Cardinal Gaspar de Borja y Velasco. Vincenzi, who was born in the Urbino region, worked as a hydraulic engineer at the Villa d’Este in Tivoli. In Rome he made his name as the inventor of the wind gun and the mobile fountain, inventions that were disseminated through the works of Benedetto Castelli and, above all, those of Giovanni Faber who also served as an intermediary, recommending Vincenzi’s services to cardinals such as Emmanuele Pio di Savoia and taking it upon himself to find buyers for the wind gun. Vincenzi worked for the Bentivoglios on the b…
Towards reactive navigation and attention skills for 3D intelligent characters
2003
This paper presents a neural design which is able to provide the necessary reactive navigation and attention skills for 3D embodied agents (virtual humanoids or characters). Based on Grossberg's neural model of conditioning [6], as recently implemented by Chang and Gaudiando [7], and according to the Adaptative Resonance Theory (ART) and the neuroscientific concepts associated, the neural design introduced has been divided in two main phases. Firstly, an environmentcategorization phase, where an on-line pattern recognition and categorization of the current agent sensory input data is carried out by a self organizing neural network, which will finally provide the agent's short term memory la…
¿Prudencia o Sabiduría? Sinonimia e interacción visual
2020
Tanto la Sabiduría como la Prudencia han sido tratadas como términos sinónimos desde la Antigüedad. Ambos conceptos se personificaban mediante la diosa Atenea/Minerva. Estas correspondencias han dado lugar a un intercambio de papeles, siendo considerada la Sabiduría como una de las Virtudes Cardinales. Asimismo, en las alegorías de la Prudencia y la Sabiduría encontramos atributos idénticos que responden al mismo significado y función, concretamente: el aspecto armado, el libro, la lechuza, la criba o cedazo y la presencia de algún objeto lumínico.
Pedro Sánchez Ciruelo. A Commentary on Sacrobosco’s Tractatus de sphaera with a Defense of Astrology
2020
AbstractThis paper focuses on the figure of the Spanish scholar Pedro Sánchez Ciruelo (ca. 1470–1548), who published a commentary on Johannes de Sacrobosco’s Sphaera in 1498. The aim of this study is to analyze the defense of astrology that Ciruelo prepared for the preface of his commentary in order to show that this praise of astrology represents a significant part of the scholar’s intellectual interests, which remained constant throughout his career. It is possible to get a richer understanding of Ciruelo’s defenses of astrology in several of his works by placing them in their own specific context: the first one in the context of the prohibition of Simon de Phares’s activities in Paris in…
The frontiers of the virtual photons program at MAMI
2012
The most recent results and the future physics program of the high precision electron-scattering experiment at MAMI are briefly outlined. The A1 high-resolution spectrometers facility allows for a unique quality of virtual photon experiments. High precision form factor measurements, few-baryon systems highresolution structure studies and the innovative way in the search of dark photons illustrate the interplay between such diverse fields as precision atomic physics, nuclear astrophysics and astroparticle physics, where hadron physics plays a central and connecting role.
