Zachowanie dziedzictwa kulturowego i popularyzacja na podstawie badań archeologicznych na cmentarzyskach wczesnośredniowiecznych
2015
Archeologia zajmuje szczególne miejsce wśród nauk o przeszłości społecznej. To nauka zajmująca się źródłami, które sama "odkrywa i tworzy", a badacz owych źródeł to ktoś, kto w swojej pracy powinien być i historykiem i psychologiem. Jeśli zajmuje się cmentarzyskami - etykiem i detektywem zarazem, ponieważ to z czym ma do czynienia jest ukryte w gąszczu źródeł, kontekstów czy ludzkich emocji. Jako nauka humanistyczna związana z naukami przyrodniczymi i technicznymi, archeologia wykorzystuje i przenosi zdobycze technologii nowoczesnej na podłoże służące poznaniu przeszłości pradziejowej i średniowiecznej. Badania te polegają między innymi na odkrywaniu, ale też na obserwacji pozostałości po k…

Experimental BIM applications in Archaeology: a work-flow
2014
In the last few decades various conceptual models, methods and techniques have been studied to allow 3D digital access to Cultural Heritage (CH). Among these is BIM (Building Information Modeling): originally built up for construction projects, it has been already experimented in the CH domain, but not enough in the archaeological field. This paper illustrates a framework to create 3D archaeological models integrated with databases using BIM. The models implemented are queryable by the connection with a Relational Database Management System and sharable on the web. Parametric solid and semantic models are integrated with 3D standardized database models that are finally manageable in the pub…
Affine Illumination Compensation on Hyperspectral/Multiangular Remote Sensing Images
2011
The huge amount of information some of the new optical satellites developed nowadays will create demands to quickly and reliably compensate for changes in the atmospheric transmittance and varying solar illumination conditions. In this paper three different forms of affine transformation models (general, particular and diagonal) are considered as candidates for rapid compensation of illumination variations. They are tested on a group of three pairs of CHRISPROBA radiance images obtained in a test field in Barrax (Spain), and where there is a difference in the atmospheric as well as in the geometrical acquisition conditions. Results indicate that the proposed methodology is satisfactory for …
Spectro-temporal reflectance surfaces: a new conceptual framework for the integration of remote-sensing data from multiple different sensors
2012
The conflict between spatial and temporal resolution of satellite systems, as well as the frequent presence of clouds in the images, has been a traditional limitation of remote sensing in the optical domain. Nevertheless, most of the conceptual tools and algorithms developed classically in remote sensing are based on the input of a series of cloud-free images from identical sensors. In this study, we propose a conceptual framework that is able to ingest data from several different sensors, make them homogeneous, eliminate clouds virtually, and make them usable in a flexible, efficient, and transparent way. The methodology is based on previous developments such as spatial ‘downscaling’, temp…
Remote Sensing Geometric Corrections
2016
This article reviews the different aspects of geometrical processing of remote sensing data, discussing error sources and methods to determine the transformation from the image acquisition geometry to the output cartographic product. Resampling methods are discussed to transform the input image to the output geometry. Several practical examples of remote sensing platforms are discussed, including satellite cases and airborne sensors. Validation of the resulting geometrical processed products is also discussed. Spatial mosaicking techniques and multitemporal composites used to produce multisource integrated products and advanced applications are finally considered, keeping a perspective on t…
The history of human-induced soil erosion: Geomorphic legacies, early descriptions and research, and the development of soil conservation—A global sy…
2013
Abstract This paper presents a global synopsis about the geomorphic evidence of soil erosion in humid and semihumid areas since the beginning of agriculture. Historical documents, starting from ancient records to data from the mid-twentieth century and numerous literature reviews form an extensive assortment of examples that show how soil erosion has been perceived previously by scholars, land surveyors, farmers, land owners, researchers, and policy makers. Examples have been selected from ancient Greek and Roman Times and from central Europe, southern Africa, North America, the Chinese Loess Plateau, Australia, New Zealand, and Easter Island. Furthermore, a comprehensive collection on the …
La distribution des tuiles estampillées de la VIIIe légion Augusta autour de Mirebeau-sur-Bèze (Côte-d'Or, France)
2011
The 8th Augustan Legion was installed at Mirebeau-sur-Bèze (Côte-d'Or) after 70 AD following the troubles that arose with the Lingons. It remained there until the time of Domitian, a period of roughly twenty years, during which time the soldiers produced tiles stamped with the name of the legion. Analysis of the dispersion of the tiles in the region around Mirebeau shows that they followed the communication routes. Consideration of the contexts in which these tiles were used, their number on each site and the resources necessary to manufacture them reveals that the 8th Legion may have played a significant role in the diffusion and adoption of tiled roofs, a construction technique that was t…
CAPITAL FLOW BONANZAS AS A FUNDAMENTAL INGREDIENT IN SPAIN'S FINANCIAL CRISES, 1850-2015
2020
El trabajo analiza los mecanismos a través de los cuales los flujos de capital produjeron inestabilidad financiera en España durante un período de 165 años. Se estudia por qué y cómo las bonanzas de capital hacen que las crisis sean más probables y severas, y si su incidencia varía en función de los tipos de crisis (crisis cambiaria, bancaria y de deuda). Concluimos que la mayoría de ellas se produjeron en diferentes regímenes de política monetaria pero que se asociaron a bonanzas de capital en un marco regulatorio liberal, lo que contribuyó a una mayor probabilidad y a una mayor gravedad de las crisis. El análisis de los diferentes regímenes de política monetaria, las estructuras financier…
