Split-Window Coefficients for Land Surface Temperature Retrieval From Low-Resolution Thermal Infrared Sensors
2008
In this letter, we provide a complete set of split-window coefficients that can be used to retrieve land surface temperature (LST) from thermal infrared sensors onboard the most popular remote-sensing satellites: ERS-ATSR2, ENVISAT-AATSR, Terra/Aqua-MODIS, NOAA series-AVHRR, METOP-AVHRR3, GOES series-IMAGER, and MSG1/MSG2-SEVIRI. The coefficients have been obtained by minimization from an extensive simulated database constructed from MODTRAN radiative transfer code calculations, emissivity spectra extracted from spectral libraries, and spectral response functions of the thermal bands considered. This letter also analyzes the magnitude of the error on the LST retrieval and the contribution t…
A parody of action : Politics and pantomime in Agamben's critique of Arendt
2021
Introduction
2022
In the introduction to the volume, the editors explain the overarching aim of the volume and contextualize the main themes of its chapters. Even if the notions of biopolitics and biopower have played a crucial role in philosophy, the humanities, and the social sciences over the last decades, they have been used in various and at times diverging senses, which has also produced different narratives about the history of biopolitics. The main aim of the volume is to clarify whether and to what extent the concept of biopolitics is applicable to antiquity. To answer such questions, the chapters collected in the volume address three main topics, namely the possible presence of biopolitical discour…
The impurity of praxis : Arendt and Agamben
2023
AbstractIf politics is understood as a foundational and open-ended activity, a general problem that arises from such a framing concerns the question of how to sustain the possibility of continuous openings without converting action into permanence and closure. In this article, we approach this problematic by treating Hannah Arendt as an exemplary figure in the current of political thought that emphasizes the indeterminate nature of action. We focus more specifically on how Arendt addressed the question of sustaining action by exploring the role of forgiveness, promises, divided power, and principles of action in her thought. While we show that the task of sustaining the indeterminacy of act…
Les dynamiques du périurbain dijonnais entre 1990 et 1999
2009
Un étalement urbain accompagne désormais la croissance des villes, notamment les plus grandes. Principalement expliqué par un desserrement résidentiel, il est aussi la résultante des dynamiques de centralisation de l’emploi et de spécialisation des zones d’activité à l’intérieur des aires urbaines. L’exemple dijonnais met bien en lumière ce double mouvement qui affecte les communes de sa périphérie et contribue à accroître les mobilités. Urban sprawl arises from the growth of cities, especially of the biggest cities. This urban sprawl is accounted for mainly by residential clearing. It results also from the dynamics of centralization of employment and from specialization of activity zones i…
Selective recovery of phosphorus as AlPO4 from silicon-free CFB-derived fly ash leachate
2018
The prospect of phosphorus (P) recovery from siliceous fly ash was investigated. The phosphorus content in the pristine fly ash was 1.21%. Obtaining pure phosphorus products from fly ash is very challenging because of high concentration of other elements, silicon (Si) at 17.3% being the major contaminant. The fly ash was fractionated with sieve size of 125 μm to concentrate the phosphorus in the small-size fraction, which also facilitated the removal of 78% of silica (Si) in the solid phase. The fractionated fly ash was treated with 8 M HCl in order to remove 98% of Si by aging (5 h) of leachate until precipitation of Si-gel, and a phosphorus-rich solution is obtained. Iron (Fe) is also con…

Kampania wielkopolska i kujawska Chryzostoma Jana Niemiry Gniazdowskiego
2020
W pracy przedstawiony został przebieg kampanii wielkopolsko-kujawskiej, która trwała dziewięć miesięcy, od lutego do października 1716 r. Przyjętym przez tarnogrodzian celem było rozszerzenie związku konfederackiego na Wielkopolskę właściwą, a następnie Kujawy i Pomorze. Poprowadzona została przez regimentarza, pułkownika Chryzostoma Jana Niemirę Gniazdowskiego - jeśli nie najzdolniejszego, to niewątpliwe najbardziej rzutkiego, skorego do podejmowania ryzykownych akcji, a przy tym skutecznego dowódcę konfederackiego. Jego przeciwnikiem były wojska królewskie złożone z oddziałów saski i polskich, dowodzone przez generała porucznika Kaspra von Seidlitz oraz generałów majorów Aleksandra Dietri…
Measurement and correction of atmospheric effects in O<inf>2</inf>-B and O<inf>2</inf>-A absorption bands in the context of s…
2014
Under sun-light illumination, the shape of the atmospheric oxygen bands (O 2 -B, 687 nm and O 2 -A, 760 nm) of the vegetation radiance is modified by chlorophyll fluorescence. However for far-range measurements, atmospheric effects also modify this shape. In this study, measurements in O 2 -A and O 2 -B absorption bands have been performed at different altitudes up to 3123 m over bare soil and wheat fields. It is observed that bands depth increase significantly with altitude. In O 2 -B band, the total magnitude of variation is of the same order of magnitude as the change induced by vegetation fluorescence, while it is much greater in O 2 -A band. We used MODTRAN 4 to correct measurements fr…
Dynamic 2- and 3-connectivity on planar graphs
1992
We study the problem of maintaining the 2-edge-, 2-vertex-, and 3-edge-connected components of a dynamic planar graph subject to edge deletions. The 2-edge-connected components can be maintained in a total of O(n log n) time under any sequence of at most O(n) deletions. This gives O(log n) amortized time per deletion. The 2-vertex- and 3-edge-connected components can be maintained in a total of O(n log2n) time. This gives O(log2n) amortized time per deletion. The space required by all our data structures is O(n).
