High tEmperature therMal Emissivity of Refractory mEtamaterials – HEMERE
Thermal emission is one of the main mechanisms of heat transfer, which will allow a hot object to cool down. The radiation emitted has a spectrum described by Planck's law, and is mainly in the infrared. This radiation can be detected as soon as it occurs in the transparency bands of the atmosphere
Developments to improve performances of axisymmetric MEMS gyroscopes – DEGAS
After many years of continuous improvement at the international level, the precision of MEMS (Micro Electro Mechanical System) type gyros has been capped at a few ° / h for several years. Work has recently been launched in France to study ways of improvements (IMEMS NG project at the DGA, NExt4MEMS
Improving lattice-based signature schemes and applications to advanced cryptographic functionalities – AMIRAL
Cryptography applications inevitably come into play when a communication between several entities must be secured. We see their expressions in everyday financial transactions, military or government communications, or between individuals when consulting medical data or even simple exchanges in a so
REpeated Exposure to Low-level Blasts : Risk Analysis for development of chronIc Neurotrauma – REELBRAIN
The tolerance limits of the human head to impacts have been mainly studied in the field of automotive industry, in connection with road safety. Nonetheless, head impacts are also frequent and need to be further studied in the field of defense. In particular, the effects of head exposure to low-level
Microcrystalline SiC/Si3N4 matrix composites for high temperature applications thought a PIP-CVI hybrid process – MATRIX
To face the energy, environmental and economic challenges of air transportation, significant efforts are devoted to the next generation of aircraft turbojets, particularly in the field of advanced materials and their elaboration processes. The main objective is a decarbonisation of air transportatio
Statistical learning for multi-dimensional SAR imagery – ASTRAL
SAR (Synthetic Aperture Radar) imagery is based on the emission of electromagnetic microwaves that are then backscattered by the elements on the ground surface, thus allowing the measurement of their physical properties. The relative phase shift of the waves received by the radar, measured by combin
3D Dielectric Resonator Antennas for Wideband Array – 3DRAW
The 3DRAW project takes place in the current context of a sharp increase in the integration density of electronic systems for communication, tracking or surveillance equipment.
