The purpose of this research is to study the place of the “Séré de Rivières” type fortification in the geomorphological dimension of the war landscape. A multiscalar approach is proposed to analyze the geomorphological context of this defensive system. It appears that the rationalization of the relief is effective at all scales: the defensive syste...
Quantitative structural models (QSMs) are frequently used to simplify single tree point clouds obtained by terrestrial laser scanning (TLS). QSMs use geometric primitives to derive topological and volumetric information about trees. Previous studies have shown a high agreement between TLS and QSM total volume estimates alongside field measured data...
De alltmer påtagliga klimatförändringar som sker runt om i världen ställer allt större krav på varje enskilt land att minska utsläppen av fossila bränslen. Därav jobbar både Sverige och många andra länder för de globala målen, som bland annat innebär att lösa klimatkrisen innan år 2030. För att uppnå detta mål krävs en stor omställning i samhället,...
In this report, remote sensing with Light Detection and Ranging (LIDAR) was demonstrated. In particular, a Frequency Modulated Continuous Wave (FMCW) LIDAR was used to reconstruct the motion of a moving target. Measurements were performed at the single photon level using a Superconducting Nanowire Single Photon Detector (SNSPD) and velocity and dis...
Light Detection and Ranging (Lidar) is a kind of active sensor that emits a laser pulse and primarily measures the time of flight of the returning pulse and uses it to construct a 3D point cloud of the scene around the lidar sensor. The constructed point cloud is an essential asset for the control of autonomous vehicles, and especially today, an es...
With the recent development of the joint classification of hyperspectral image (HSI) and light detection and ranging (LiDAR) data, deep learning methods have achieved promising performance owing to their locally sematic feature extracting ability. Nonetheless, the limited receptive field restricted the convolutional neural networks (CNNs) to repres...
Between August and November 2016, three major earthquake events occurred in Central Italy. The first event, with M6.1, took place on 24 August 2016, the second (M5.9) on 26 October, and the third (M6.5) on 30 October 2016. As part of the Italy-US GEER team investigation, we recorded the amplitude and character of offset on the Mount Vettore Fault Z...

Human intervention is still required nowadays for most operations conducted during the Dismantling & Decommissioning (D&D) steps, which cover a wide range of radiological conditions: from the harsh initial conditions, nearly identical to when operating, to the final decommissioning steps where radioactivity has been removed. The goal of the three y...
En parallèle de ses monuments antiques et de ses édifices religieux, le patrimoine bâti de Reims, « Cité des Sacres et du Champagne », est également militaire. La ville est notamment dotée d’une ceinture de 13 ouvrages fortifiés portant de l’artillerie et détachés de la ville (c. 6km), construits après la défaite de 1870, entre 1875 et 1885 (7 fort...
Le 2 octobre 2020, la tempête Alex a provoqué un événement méditerranéen exceptionnel dans les vallées alpines côtières du Var, de la Tinée et de la Roya. Dans la vallée de la Roya, les précipitations ont atteint jusqu'à 665 mm au lac des Mesches, entraînant d'importants changements morphologiques du fleuve Roya et de ses affluents. Après la tempêt...
