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,...
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....
Zephyr Drone Simulator Integrates NIST Payload Delivery Test for Public Safety Drone Training
Public safety drone pilots can now train for critical lifesaving missions using a high-fidelity simulation environment featuring new standardized test methods developed by NIST and leading emergency response organizations Zephyr Drone Simulator (ZDS) has integrated a...
MMB VOLUM-e, la fabrication additive au service de l’excellence
À Blangy-sur-Bresle (Seine-Maritime), la PME normande MMB VOLUM-e coconçoit et fabrique des pièces complexes pour l’automobile, l’aérospatiale, le luxe… Héritière d’un savoir-faire industriel centenaire, l’entreprise a fait le pari de la fabrication additive (plus...
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...
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...
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...
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...
EECL Amplifiers Reach In-Orbit Milestone on ESA HydroGNSS Mission
Ultra-low-noise amplifiers developed by European Engineering & Consultancy Ltd. (EECL) are now operating successfully in orbit on the European Space Agency’s HydroGNSS Earth observation mission, marking an early technical milestone for the satellite payloads. The...
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...
