At the beginning of the early modern period, the west of the Holy Roman Empire was a territorially fragmented landscape: Besides a few larger principalities, a multitude of smaller and smallest largely independent territories existed. But in the regional context, the relationships proved to be even more complex; they were characterised by overlapping feudal rights and high court districts, by joint dominions of two, three or more seigneurs, by disputed territories and many other forms of dependencies. A cartographic recording of these complex and multidimensional spatial structures was not possible by the means of the time. The rise of an increasingly scientific cartography from the mid-15th century onwards allowed the princes of larger territories to use cartographic representations as instruments of power: on the one hand, as a basis for the political and administrative development of their territories, on the other hand, as a medium for the dissemination of territorial claims and for the representation of dominion. The analysis of selected maps shows the various strategies used to construct the fragmentary possessions as closed territories. For this purpose, borders in the form of lines were defined on maps from the middle of the 16th century onwards, although linear frontiers between two territories mostly did not exist at that time.

Improving Long-Term Retention through Personalized Recall Testing and Immediate Feedback

Tests have been shown to improve the long-term retention of students, referred to as the "testing effect". Different question formats, such as multiple choice and recall, have varying properties. While recall questions induce a longer retention than multiple choice ones, they are harder for students since answers must be actively retrieved from memory. Moreover, regular testing inherently increases the teacher's workload, particularly since feedback on each test is paramount for an effective bearing on the student's understanding and learning. This work introduces BEACON Q, a digital quiz application combining different question formats and progressively adapting their difficulty to each student’s level. The level is derived from past answers as well as ratings provided by the students which constitute their perceived understanding of each topic. BEACON Q delivers immediate feedback through detailed explanations, without requiring manual assessment by the teacher. Tests are scheduled for periods of time, thus giving the students the flexibility to choose an appropriate time to take the test. An initial evaluation of BEACON Q has been performed in the context of three different computer science classes at our university. Preliminary results are presented in this paper. [less ▲]

Varier les supports et les ressources pour enseigner le lexique en classe de français

La perspective actionnelle, au centre des cours de langues depuis les années 2000, prend en compte le besoin de communiquer des apprenants. Ces derniers sont habitués à réaliser des tâches en contexte pour communiquer dans la langue cible, alors comment rendre aujourd’hui l’apprentissage du lexique dynamique pour nourrir ces interactions dans le contexte multilingue de l’enseignement secondaire au Luxembourg ? Dans cette communication, nous allons explorer plusieurs ressources (l’art et des applications numériques spécialisées sur le lexique) et les travailler sur différents supports (le téléphone et les tablettes). Ces outils didactisés offrent des stratégies d’enseignement-apprentissage en classe inversée ou en enseignement hybride, tout en permettant -nous le verrons-, de maintenir l’attention des élèves en cours de français. Cette démarche facilite également la mise en place de la pédagogie différenciée auprès d’un public aux niveaux hérétogènes (Français Langue Etrangère, Français Langue Seconde, et Français Langue Maternelle).

Understanding, quantifying and monitoring soil moisture is important for many applications, e.g., agriculture, weather forecasting, occurrence of heatwaves, droughts and floods, and human health. At a large scale, satellite microwave remote sensing has been used to retrieve soil moisture information. Surface water has also been detected and monitored through remote sensing orbital platforms equipped with passive microwave, radar, and optical sensors. The use of reflected L-band Global Navigation Satellite System (GNSS) signals represents an emerging remote sensing concept to retrieve geophysical parameters. In GNSS Reflectometry (GNSS-R) these signals are repurposed to infer properties of the surface from which they reflect as they are sensitive to variations in biogeophysical parameters. NASA's Cyclone GNSS (CYGNSS) is the first mission fully dedicated to spaceborne GNSS-R. The eight-satellite constellation measures Global Positioning System (GPS) reflected L1 (1575.42 MHz) signals. Spire Global, Inc. has also started developing their GNSS-R mission, with four satellites currently in orbit. In this thesis we propose and validate a method to retrieve large-scale near-surface soil moisture and a method to map and monitor inundations using spaceborne GNSS-R. Our soil moisture model is based on the assumption that variations in surface reflectivity are linearly related to variations in soil moisture and uses a new method to normalize the observations with respect to the angle of incidence. The normalization method accounts for the spatially varying effects of coherent and incoherent scattering. We found a median unbiased root-mean-square error (ubRMSE) of 0.042 cm3 cm-3 when comparing our method to two years of Soil Moisture Active Passive (SMAP) data and a median ubRMSE of 0.059 cm3 cm-3 compared to the observations of 207 in-situ stations. Our results also showed an improved temporal resolution compared to sensors traditionally used for this purpose. Assessing Spire and CYGNSS data over a region in south east Australia, we observed a similar behavior in terms of surface reflectivity and sensitivity to soil moisture. As Spire satellites collect data from multiple GNSS constellations, we found that it is important to differentiate the observations when calibrating a soil moisture model. The inundation mapping method that we propose is based on a track-wise approach. When classifying the reflections track by track the influence of the angle of incidence and the GNSS transmitted power are minimized or eliminated. With CYGNSS data we produced more than four years of monthly surface water maps over the Amazon River basin and the Pantanal wetlands complex with a spatial resolution of 4.5 km. With GNSS-R we could overcome some of the limitations of optical and microwave remote sensing methods for inundation mapping. We used a set of metrics commonly used to evaluate classification performance to assess our product and discussed the differences and similarities with other products. [less ▲]

Global warming has increased uncertainty regarding managing traditional water supply systems. Unfortunately, there is a need for the smart management of water supply systems. This work aims to design a solution for renewing and securing critical infrastructure that supplies water and provides water purification inside the range of applications of Industry 4.0 for Smart Cities. Therefore, we analyze the renewal requirements and the applicable use cases and propose a solution based on IoT networks for critical infrastructure in the urban environment. We describe the architecture of the IoT network and the specific hardware for securing a water supply and wastewater treatment chain. In addition, the water level control process for the supply chain and the system that ensures the optimal level of chemicals for wastewater treatment are detailed. Finally, we present the guidelines for infrastructure operators to carry out this operation within Industry 4.0, constituting a development framework for future research on the design of Smart Cities.
