A comparative study between Pléiades and UAV images has been conducted for precision viticulture applications in the Aquitaine region over Buzet vineyard and two Bordeaux domains. This study has shown a good agreement between the results obtained from the different sensors, both for the characterisation of the vine plots and for the vineyard vigour assessment. Especially local vineyard heterogeneities and variabilities can be demonstrated on Pléiades imagery, which is consequently of interest for the characterisation of vineyards at regional scale. However detection of small structures is limited by Pléiades spatial resolution especially where the vine row distance is narrow (less than 2 metres). Use of alternate technologies with better spatial resolution such as Unmanned Aerial Vehicles (UAV) is relevant for more accurate plot parameter characterisations.

Microelectronics Reliability | Year: 2015

The industries of transportation as the space industry are faced with a strong global economic competition which sets economic constraints on the cost of the functions. The use of COTS (Commercial Off-The-Shelf) components in embedded systems is more and more necessary to shorten the development cycles and reduce manufacturing costs. The application of electronic components comes overwhelmingly from public sectors whose requirement is to provide, in short development cycles, technological innovations including risk and cost mitigation. These development cycles must incorporate the specific constraints of embedded systems in terms of reliability, dependability, and availability, held in harsh environment and life.Due to the low volume of components supplying the market of embedded systems, component manufacturers are unlikely to provide information necessary to supporting folders for certification or qualification. It is therefore necessary for the Space, Aeronautics and Automotive industries to characterize the performance and robustness of these COTS components in the operational and environmental conditions of their applications.This paper presents the objectives and main challenges of a sponsored project dedicated to characterize and model COTS reliability. © 2015.

We propose a simplified but efficient scenario for a manned Mars mission. The idea is to select a crew of only 2 astronauts and to bring in situ resource utilization systems in the same vehicle. For security reasons, we suggest duplicating the mission as it was proposed by Von Braun. At very moment of the journey, the two vehicles would stay close so that each crew could provide help to the other. We show that this scenario is much simpler than the last design reference architecture proposed by NASA. The initial mass in low Earth orbit is minimized and the risks are also reduced. The total cost could be in the order of 40 billion dollars. © 2011 Elsevier Ltd.

Molecularly imprinted polymers (MIPs) are tailor-made receptors that possess the most important feature of biological antibodies and receptors - specific molecular recognition. They can thus be used in applications where selective binding events are of importance, such as chemical sensors, biosensors and biochips. For the development of microsensors, sensor arrays and microchips based on molecularly imprinted polymers, micro and nanofabrication methods are of great importance since they allow the patterning and structuring of MIPs on transducer surfaces. It has been shown that because of their stability, MIPs can be easily integrated in a number of standard microfabrication processes. Thereby, the possibility of photopolymerizing MIPs is a particular advantage. In addition to specific molecular recognition properties, nanostructured MIPs and MIP nanocomposites allow for additional interesting properties in such sensing materials, for example, amplification of electromagnetic waves by metal nanoparticles, magnetic susceptibility, structural colors in photonic crystals, or others. These materials will therefore find applications in particular for chemical and biochemical detection, monitoring and screening. © 2011 Springer-Verlag Berlin Heidelberg.
