SMOS-IC: An Alternative SMOS Soil Moisture and Vegetation Optical Depth Product
2017
© 2017 by the authors. The main goal of the Soil Moisture and Ocean Salinity (SMOS) mission over land surfaces is the production of global maps of soil moisture (SM) and vegetation optical depth (τ) based on multi-angular brightness temperature (TB) measurements at L-band. The operational SMOS Level 2 and Level 3 soil moisture algorithms account for different surface effects, such as vegetation opacity and soil roughness at 4 km resolution, in order to produce global retrievals of SM and τ. In this study, we present an alternative SMOS product that was developed by INRA (Institut National de la Recherche Agronomique) and CESBIO (Centre d'Etudes Spatiales de la BIOsphère). One of the main go…

A contribution to the inventory of parasitic microfungi on land plants in Champsaur region (French Alps, “Parc National des Ecrins”).
2023
A preliminary investigation of the flora of parasitic microfungi on land plants is reported, focused upon the mountain and the base of the subalpine ranges, in Champsaur region, (south-western French Alps, mainly within the “Parc National des Ecrins”). Sheltered by 128 host-plant species, 182 species of microfungi have been identified. Their respective distributions, among 24 investigated localities (including four located within the Central Zone of the “Parc National des Ecrins”), are specified. Moreover, seven of these 182 microfungi do not match satisfactorily any of the consulted diagnosis in the specialized literature. Accordingly, a detailed description of the main distinctive traits …
Unified Radio and Network Control Across Heterogeneous Hardware Platforms
2016
Experimentation is an important step in the investigation of techniques for handling spectrum scarcity or the development of new waveforms in future wireless networks. However, it is impractical and not cost effective to construct custom platforms for each future network scenario to be investigated. This problem is addressed by defining Unified Programming Interfaces that allow common access to several platforms for experimentation-based prototyping, research, and development purposes. The design of these interfaces is driven by a diverse set of scenarios that capture the functionality relevant to future network implementations while trying to keep them as generic as possible. Herein, the d…
INDUSTRY 4.0 AS SMART ENABLER FOR INNOVATIVE BUSINESS MODELS
2017
Master's thesis Business Administration BE501 - University of Agder 2017 Industry 4.0 is the upcoming 4th revolution within industrial setups across the world, mainly in manufacturing hubs. Industrial internet of Things (IIOT) will alter the dimensions of the way businesses used to be conducted and the way value was assessed and retrieved. IIOT tends to have a critical impact on the business models (BM) within various industrial sectors, either manufacturing or services. This study tries to observe IIOT related effects on the business models in regards to manufacturing industry from a Tech-based consultancy point of view. This study employs exploratory multiple case study approach to the to…
FLUMO: FLexible Underwater MOdem
2019
The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …

Emulating the Effects of Radiation-Induced Soft-Errors for the Reliability Assessment of Neural Networks
2021
International audience; Convolutional Neural Networks (CNNs) are currently one of the most widely used predictive models in machine learning. Recent studies have demonstrated that hardware faults induced by radiation fields, including cosmic rays, may significantly impact the CNN inference leading to wrong predictions. Therefore, ensuring the reliability of CNNs is crucial, especially for safety-critical systems. In the literature, several works propose reliability assessments of CNNs mainly based on statistically injected faults. This work presents a software emulator capable of injecting real faults retrieved from radiation tests. Specifically, from the device characterisation of a DRAM m…
Multi-agent control architecture for RFID cyberphysical robotic systems initial validation of tagged objects detection and identification using Playe…
2016
International audience; The objective of this paper is to describe and validate a multi-agent architecture proposed to control RFID Cyber-Physical Robotic Systems. This environment may contain human operators, robots (mobiles, manipulators, mobile manipulators, etc.), places (workrooms, walls, etc.) and other objects (tables, chairs, etc.). The proposed control architecture is composed of two types of agents dispatched on two levels. We find at the Organization level a Supervisory agent to allow operators to configure, manage and interact with the overall control system. At the Control level, we distinguish the Robots agents, to each robot (mobiles, manipulators or mobile manipulators) is a…
