El campo de la Sociología en España (1976-2013). Análisis sociométrico y de redes de las tesis doctorales y sus tribunales
2016
[EN]: The interest in conducting this thesis is due to two main reasons. On the one hand the strong growth of Sociology in Spain in recent times, on the other hand the lack of research on doctoral theses in the field of sociology. The purpose of this work is to study the actors involved in the developing process of Sociology doctoral theses in Spain between 1976 and 2013. The aim is to identify the structure of the underlying relationships among academics, to create a map of academic positions in the field of Sociology and to identify research trends. The methodology used to achieve the overall objective was social networks analysis, combined with statistical indicators. We selected the the…
Levantamiento del templo G. parque arqueologico de Selinunte, Trapani. Sicilia. Informe general
2006
El trabajo de campo al que se refiere la presente comunicación, se puede considerar como la fase inicial del proyecto de levantamiento del templo G de Selinunte, ya que si bien se han podido tomar muchos datos del mismo durante la campaña de verano del 2005, quedan algunas zonas donde no ha sido posible acceder, por lo que será preciso completar la información conforme se vaya avanzando en el modelo. La dificultad mayor vendrá con la definición del propio modelo 3D, labor de investigación avanzada ya que actualmente no existen técnicas ni metodologías de referencia a nivel mundial en el uso de escaners láser 3d aplicados al campo de la arquitectura. Esta segunda tarea la estamos llevando a …
Reconstrucción virtual y visualización 3d del yacimiento arqueológico Castellet de Bernabé (Lliria, España)
2017
3D virtual reconstruction of cultural heritage is a useful tool to reach many goals: the accurate documentation of our tangible cultural legacy, the determination of mechanical alteration on the assets, or the mere shape acquisition prior to restoration and/or reconstruction works, etc. Among these goals, when planning and managing tourism enhancement of heritage sites, it demands setting up specific instruments and tools to guarantee both, the site conservation and the visitors’ satisfaction. Archaeological sites are physical witnesses of the past and an open window to research works and scientific discoveries, but usually, the major structures do no exist nowadays, and the general public …
Documenting carved stones by 3D modelling – Example of Mongolian deer stones
2018
Rock art studies are facing major technical challenges for extensive documentation. Nowadays, recording is essentially obtained from time-consuming tracing and rubbing, techniques that also require a high level of expertise. Recent advances in 3D modelling of natural objects and computational treatment of the modelled surfaces may provide an alternative, and reduce the current documentation bottleneck. The aim of this study is to examine the extent to which such treatments can be applied. The case study presented here concerns the famous deer stones erected by ancient Mongolian nomad populations. The 3D acquisition workflow is based on structure-from-motion, a versatile photogrammetric tech…
Levantamiento 3D para el estudio arqueológico y la reconstrucción virtual del Santuario de Isis en la antigua Lilybaeum (Italia)
2020
[EN] In recent years, the use of three-dimensional (3D) models in cultural and archaeological heritage for documentation and dissemination purposes has increased. New geomatics technologies have significantly reduced the time spent on fieldwork surveys and data processing. The archaeological remains can be documented and reconstructed in a digital 3D environment thanks to the new 3D survey technologies. Furthermore, the products generated by modern surveying technologies can be reconstructed in a virtual environment on effective archaeological bases and hypotheses coming from a detailed 3D data analysis. However, the choice of technologies that should be used to get the best results for dif…
Documenting carved stones from 3D models. Part II - Ambient occlusion to reveal carved parts.
2021
10 pages; International audience; Revealing carved parts in rock art is of primary importance and remains a major challenge for archaeological documentation. Computational geometry applied to 3D imaging provides a unique opportunity to document rock art. This study evaluates five algorithms and derivatives used to compute ambient occlusion and sky visibility on 3D models of Mongolian stelae, also known as deer stones. By contrast with the previous companion work, models are processed directly in 3D, without preliminary projection. Volumetric obscurance gives the best results for the identification of carved figures. The effects of model resolution and parameters specific to ambient occlusio…
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…
Documentation and Archiving
2014
In this chapter a historical survey on the development of balances is presented, also in tabular form. The documentation of balance constructions in museums and literature is shown. The development of science museums, technical libraries, and societies which include balances is reviewed, and a list of museums which exhibit balances is given.
