Optimal modalities for radiative transfer-neural network estimation of canopy biophysical characteristics: Evaluation over an agricultural area with …
2011
International audience; Neural networks trained over radiative transfer simulations constitute the basis of several operational algorithms to estimate canopy biophysical variables from satellite reflectance measurements. However, only little attention was paid to the training process which has a major impact on retrieval performances. This study focused on the several modalities of the training process within neural network estimation of LAI, FCOVER and FAPAR biophysical variables. Performances were evaluated over both actual experimental observations and model simulations. The SAIL and PROSPECT radiative transfer models were used here to simulate the training and the synthetic test dataset…
What is the optimal environment for the long-term physical development of the young elite rugby player? : Study of the physical characteristics and c…

To ensure long-term sporting success, a governing body such as French Rugby Union (FFR) must implement a physical development plan from youth to senior player. In this way, federal academies have been created for players from 15 years old (category under 16 (U16)), to 17 years old and then the development continues in clubs. Throughout their youth career, players might experience U18 or U20 teams, selection which are the two only national youth French team. The aim of this thesis was to describe the physical development of young French rugby players from their entry into national pathway (U16) to U20. To achieve this, we first described the anthropometric and physical characteristics of pla…
