Online Model Predictive Control for Trajectory and Beamforming Optimization in UAV-Enabled URLLC
This paper investigates joint trajectory and active beamforming design for unmanned aerial vehicle (UAV)-enabled ultra-reliable low-latency communication (URLLC) systems under finite blocklength (FBL) transmission. Unlike conventional Shannon-capacity formulations, the FBL regime introduces a signal-to-interference-plus-noise ratio (SINR)-dependent dispersion penalty that increases the sensitivity of reliability to mobility-induced channel variations. To address this challenge, we develop a […]
PrivLocAuth: Enabling Location-Aware Cross-Domain UAV Authentication with Zero-Knowledge Location Privacy
Secure cross-domain UAV authentication is challenging because identity verification alone is insufficient to guarantee safe operation. In many UAV applications, it is equally critical to verify that a UAV is currently located within an authorized geographic region. Existing approaches often expose precise GPS coordinates, rely on static identifiers that enable tracking, or fail to guarantee […]

La fabrication additive transforme aussi les métiers de l’industrie
Si l’impression 3D s’impose progressivement dans l’industrie grâce à son fort potentiel, son déploiement repose aussi sur des compétences humaines très spécifiques. Ingénieurs, designers ou techniciens interviennent à chaque étape, de la conception des pièces à leur production. Tour d’horizon de six métiers clés. Au contraire de l’usinage, qui consiste à retirer de la matière, […]
Advanced Manufacturing-Driven Multiscale Nanostructured Metals: A Review
The rapid evolution of next-generation advanced manufacturing technologies, exemplified by additive manufacturing, has drastically expanded the accessible compositional and processing windows for metallic materials. These advances actively drive the formation of far-from-equilibrium structures and open unprecedented opportunities to design multiscale nanostructured metals with exceptional structural and functional properties. In this mini-review, we examine how multiscale […]
JEC World : les polymères techniques et les composites thermoplastiques montent en gamme grâce aux revêtements toujours innovants
Décoratifs ou fonctionnels, les revêtements sont souvent ou presque invisibles pour les non avertis. Pourtant, ils font partie d’une démarche stratégique d’une entreprise quel que soit le marché adressé. Quand Demgy associe la fabrication additive et la métallisation sélective, le produit est incontournable. Un constat traduit par Alexandre Saubot, président de France Industrie : « […]
AI-optimized design of hybrid functionally graded metal matrix composites for additive manufacturing and multifunctional engineering applications
The optimization of functionally graded metal matrix composites (FGMMCs) has long been hindered by the complex interplay between reinforcement distribution, process constraints, and multifunctional performance objectives. Current data-driven and empirical frameworks like ANN-GA hybrids, CNN-DQN models and XGBoost regressors cannot guarantee physical validity, as well as generalizability, and, as a result, provide non-manufacturable or unstable […]

Energies, Vol. 19, Pages 1475: Battery Module Thermal Management of CubeSats and Small Satellites Using Micro-/Nano-Enhanced Phase-Change Material Heat Sinks
Phase-change materials (PCMs) are capable of storing or releasing a substantial amount of thermal energy within a small volume through the latent heat of fusion during phase transitions of melting and solidification, i.e., from solid to liquid or vice versa, in a near isothermal process. However, commonly used organic PCMs, such as paraffin wax, exhibit […]

Near-unity broadband photonic metamaterial absorber for thermoelectric energy harvesting in Space
Spaceborne power systems must operate reliably for decades with minimal maintenance. Thermoelectric generators (TEGs) are intrinsically suited to long-lived missions, but their output remains constrained by available thermal gradients and the limitations of bulk thermoelectric materials. Here, we introduce a photonic metamaterial (PtMM) coating concept that amplifies the thermal gradient available to a TEG by […]
