Tomographic imaging allows to access the internal structures of objects and tissues by means ofmeasurements on different types of penetrating waves.In the first part of the talk, I will present an application of microwave tomography in the context ofmedical imaging, concerning the detection and monitoring of brain strokes.In the second part of...

La fouille du site de La Teuleria (Saint-Génis-des-Fontaines, Pyrénées-Orientales) en 2018 par la société ACTER a mis en évidence une occupation domestique du Néolithique moyen datée de la fin du 5e millénaire. L'assemblage céramique associé à ces vestiges présente les caractéristiques des faciès dits « post-cardiaux » renvoyant à la notion de...

Does fragment size influence significantly archaeological charcoal spectra? Does the floristic content of charcoal concentrations provide a representative image of the anthracological record? These taphonomy-related questions are as old as the first methodological groundwork in anthracology and therefore, they could be considered as solved. The...

Whether one is interested in paleoeconomic or technical aspects related to the use of fire, or in taphonomy, the concept of temperature is central in charcoal analysis. Based on experimental results, we will provide an overview of the concept of temperature in anthracology, covering both its theoretical and epistemological aspects.What does the...

Archaeological studies involve more and more numerical data analyses. In this work, we are interested in the analysis and classification of ceramic sherds tomographic images in order to help archaeologists in learning about the fabrication processes of ancient pottery. More specifically, a particular manufacturing process (spiral patchwork) has...

Céramiques imprimées de Méditerranée occidentale: apports de la micro-tomographie à la restitution des traditions céramiques en contexte archéologique

International audience

International audience

Identifying the making of prehistoric pottery is one of the valuable means of tracing technical traditions and human mobility. We are interested here in the settlement in the Western Mediterranean through the sorting of pottery samples. The aim is to discriminate between two building techniques, looking for the features formed by the air...

Micro-computed tomography is a valuable tool for studying ancient ceramics technology. Analysing pottery 3-D images is a challenging issue, the data being extremely noisy and heterogeneous. Quantitative criteria are introduced for the characterisation of a previously unrecognised pottery building method, the Spiralled Patchwork Technology...

Brain stroke is a major cause of disability and death worldwide. There are two types of stroke, ischemic or cerebral infarction (85% of cases) and hemorrhagic (15%). The diagnosis must be made quickly (within 3 to 4 hours after the onset of symptoms) to determine the nature of the stroke and proceed to treatment. Recent works have shown the...

Brain strokes are one of the leading causes of disability and mortality in adults in developed countries. The ischemic stroke (85% of total cases) and hemorrhagic stroke (15%) must be treated with opposing therapies, thus the nature of the stroke must be determined quickly in order to apply the appropriate treatment. Recent studies in...

The macro- and mesoscopic analysis of the Impresso-Cardial pottery assemblage from the Pendimoun rock shelter located in Castellar (Alpes-Maritimes, France) revealed a range of previously unrecognised macrotraces and mesostructures on all pottery vessels, independently of their shape or size. These traces suggested a forming sequence involving...
