Global Estimation of Biophysical Variables from Google Earth Engine Platform
2018
This paper proposes a processing chain for the derivation of global Leaf Area Index (LAI), Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), Fraction Vegetation Cover (FVC), and Canopy water content (CWC) maps from 15-years of MODIS data exploiting the capabilities of the Google Earth Engine (GEE) cloud platform. The retrieval chain is based on a hybrid method inverting the PROSAIL radiative transfer model (RTM) with Random forests (RF) regression. A major feature of this work is the implementation of a retrieval chain exploiting the GEE capabilities using global and climate data records (CDR) of both MODIS surface reflectance and LAI/FAPAR datasets allowing the global estim…
TISSBERT: A benchmark for the validation and comparison of NDVI time series reconstruction methods
2018
[EN] This paper introduces the Time Series Simulation for Benchmarking of Reconstruction Techniques (TISSBERT) dataset, intended to provide a benchmark for the validation and comparison of time series reconstruction methods. Such methods are routinely used to estimate vegetation characteristics from optical remotely sensed data, where the presence of clouds decreases the usefulness of the data. As for their validation, these methods have been compared with previously published ones, although with different approaches, which sometimes lead to contradictory results. We designed the TISSBERT dataset to be generic so that it could simulate realistic reference and cloud-contaminated time series …
On the degree of binder activity of reclaimed asphalt and degree of blending with recycling agents
2020
It is common practice to assume full blending of the aged binder of reclaimed asphalt (RA) within the design of new asphalt mixtures. Although being practical, this assumption has often led designers to asphalt mixtures lacking binder. Hence, going towards recycled asphalt mixtures (RAM) there is a need to have a better understanding of the blending phenomena, to have a general agreement on terminology and finally adapting RA classification and mix design procedures accordingly. This manuscript aims at being both a reference and stimulus for the scientific community to work in this direction and on this basis provides a nomenclature and a theoretical framework of the blending phenomena. The…
Increasing the flexural capacity of RC beams using steel angles and pre-tensioned stainless steel ribbons
2016
This article presents an experimental programme on reinforced concrete beams retrofitted with steel angles and pre-stressed stainless steel ribbons to increase their flexural strength and ductility. Two different configurations of the steel ribbon were designed, and two companion specimens for each type considered were subjected to a four-point bending test to facilitate a direct comparison in the analysis of the effectiveness of the retrofitting technique. The influence of longitudinal steel angles and transverse stainless steel ribbons is analysed, and the concrete confinement due to stainless steel ribbons examined. The strengthened beams show remarkable increments in flexural strength a…
The Village of the Year Competition Constructing an Ideal Model of a Rural Community in Finland
2016
The Village Action Association of Finland (SYTY) organizes the Village of the Year competition annually to award active rural communities. The competition has taken place since 1985, but after the village action movement was integrated into Finnish rural policy networks in the 1990s, it also became a part of rural policy instruments. The competition can be considered a governing technique that constructs norms and an ideal model for rural communities to pursue. In this article, I study the representation of an ideal rural community by analysing the criteria of the competition. I also look for changes to see whether the integration of the village action movement into rural policy is reflecte…
Political community resilience in declining rural areas in Finland
2021
Abstract In this article, we study how declining rural communities build political resilience in Finland. Community resilience is an adaptive process through which rural communities try to maintain their viability in changed circumstances. This process does not entail a submissive attitude, but rather active agency and an effort to influence matters concerning the community’s well-being. We focus on the political dimension of resilience by identifying different local tactics that rural communities adopt to promote their own development following municipal mergers. We classify these tactics into three categories: cooperation, conflict and community-led development. The significant difference…
Educate to coexist with the flood risk
2020
In the Mediterranean region, floods are the main natural risk. This hazard has been aggravated in recent decades by the increase in exposure of the human being and is expected to increase the danger according to the forecast of climate change scenarios. For this reason, dealing with these issues in the classroom and the training of teachers on this subject should be a priority, as established in the curriculum of Primary Education (Social Sciences). The objectives of this research are: 1) To analyze the knowledge that future teachers have about the risk of flooding to develop these contents in the classroom; 2) Check the relevance that they give to this social-environmental problem; and 3) …
Innovazione sociale e creatività. Nuovi scenari di sviluppo per il territorio sicano
2018
Innovazione sociale e creatività. Nuovi scenari di sviluppo per il territorio sicano, attraverso il paradigma emergente della Circular Land e alcune esperienze d'innovazione locale in Sicilia, traccia un nuovo scenario di sviluppo in Sicilia, evidenziando le relazioni tra l'innovazione sociale, quale processo territorialmente radicato e il contesto spaziale in cui agisce, e identificando nella dimensione relazionale della connettività il principale campo d'azione per le politiche territoriali regionali. In the contribution Innovation and creativity. New development scenarios for the Sicani area, starting from the emerging concept of Circular Land and from some experiences of local innovatio…
Catholicisme, patriotisme et sport en Alsace (1898-1939)
2002
L’Elsässischer Turnerbund, devenue en 1918 l’Avant-garde du Rhin, avait pour principe de faire des sportifs de bons catholiques et de bons patriotes. Cet objectif rejoignait en théorie celui de la Fédération gymnastique et sportive des patronages de France à laquelle elle était affiliée depuis la fin de la Première Guerre mondiale. Très vite cependant elle se distingua par sa volonté farouche de préserver son identité régionale et sa conception fédéraliste de la nation.
Méthodologie de modélisation et de caractérisation des réseaux spatiaux. Application au réseau viaire de Paris
2016
International audience; Les graphes spatialisés soulèvent différentes questions qui intéressent plusieurs disciplines, depuis la biologie (veinures de feuilles, réseaux neuronaux) ou la géomorphologie (réseaux fluviaux) jusqu’aux études urbaines (réseaux de transports), sans oublier celle des réseaux d’énergie (réseaux électriques, de gaz ou de pétrole) et de télécommunication. Nous nous concentrerons ici sur les exemples apportés par les réseaux viaires. C’est à travers ceux-ci que nous définirons dans cet article d’abord un objet d’étude multi-échelle, la voie, puis cinq indicateurs liés qui permettront une lecture enrichie de la spatialité urbaine. Nous expliciterons ainsi les particular…
