Multi-modal image fusion for small animal studies in in-line PET /3T MRI
2015
Congrès sous l’égide de la Société Française de Génie Biologique et Médical (SFGBM).; National audience; In the framework of small animal multi-modal imaging, the current progression of the IMAPPI project is illustrated by the design of an in-line PET/MRI prototype, coupled to a dedicated multi-resolution registration method allowing the robust fusion of data coming from both modalities. The first results show a good alignment of the data from tumor imaging at the level of the abdomen.
Approche multi-critère pour la caractérisation des adventices
2022
The objective of this thesis is to develop a way to detect weeds in a field using multispectral images, in order to determine which weeds should be eliminated during the current crop cycle and more particularly at the early stages. The multi-criteria approach focuses on the spatial arrangement, the spec- tral signature, the morphology and the tex- ture of the plants located in the plots. This work proposes a method for selecting the best criteria for optimal discrimination for a given setup. Prior to the extraction of these crite- ria, a set of methods was developed in order to correct the errors of the acquisition de- vice, to precisely detect the vegetation and then to identify within the…

Robotics for weed control: I-Weed Robot for a specific spraying
2012
International audience; To preserve environment for a sustainable agriculture, we explore the development of a new autonomous robot, called I-Weed Robot (Intelligent Weed Robot), which aims at reducing herbicides in crop fields (maize, sunflower...). Using a high precision positioning signal (RTK) to locate the robot in the field, a Kaman filter and a proportional-integral-derivative controller (PID controller) allow adjusting the orientation of the robot depending on a predefined trajectory. As for the spraying system, a camera in front of the mobile platform detects weed plants thanks to an image processing based on a crop/weed discrimination algorithm (Hough Transform). At the back a spr…
Pierres et carrières : réflexions autour de différentes stratégies d’approvisionnement sur les chantiers bourguignons médiévaux
2021
In this paper, we want to discuss the complexity of the mechanisms of medieval building stone supplying based on a diachronically and multidisciplinary inquiry on several Cistercian and ducal study cases. The first results enlighten the constraint caused by land property that limits the builders to a supplying network shaped by domain and law. Thanks to the growing vitality of trade and the arrival of independent stone providers, criteria of selection gradually focus on stone itself. Both global and individual strategies evolve then, reinventing the networks of stone providing and the markets.

La Constitution de 1848 face au risque de césarisme
2001
International audience; La Constitution de 1848 est-elle l'une des causes majeures du coup d'État du 2 décembre 1851 ? L'analyse des débats montre pourtant la volonté d'éviter tout retour au césarisme, et ce, dès la commission de la Constitution qui présente le 19 juin 1848 un projet préliminaire. Les constituants entendent fonder une République démocratique, stable, susceptible de rivaliser avec les puissances étrangères, en établissant des pouvoirs forts qui émanent du peuple Cependant, la confiance absolue donnée à la démocratie occulte le risque d'une République sans républicains. Le régime politique mis en place suit une logique propre répondant à la volonté de concilier la nécessité d…
Impression 3D et propriété intellectuelle: Un aperçu français
2019
Technological developments and the expiry of patents in three-dimensional printing are making this technology less and less expensive and with increased performance. Now widespread in the manufacturing industry, 3D printing is about to cross the threshold of our homes. The dematerialization of objects into exchangeable digital files raises many questions about the enforcement of intellectual property rights in French Law.
