Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...

NanoSentry: An Edge‐Deployable Unified Neural Architecture for Multi‐Domain Industrial Prognostics and Health Management

Artificial Intelligence for Engineering, EarlyView.
NanoSentry, a sub‐50 KiB unified architecture for multi‐domain prognostics, matches or outperforms models 4.5× $4.5\times $ larger across turbofan, battery, and bearing benchmarks while reducing end‐of‐life prediction error up to 5.8× $5.8\times $. Physical STM32H7 deployment confirms sub‐3 ms inference and up to 26 KiB peak SRAM without quantisation ...

Bypass Turbojet Engines [PDF]

Proceedings of Higher Educational Institutions. Маchine Building, 2019
Subsonic bypass turbojet engines of the fifth generation have reached technical maturity, with overall efficiency of 35–38%. Without changing the thermodynamic cycle of the engine, any further work in this direction is futile. The researcher proposes a method of increasing the thermodynamic effectiveness of heat engines based on the so called internal ...

Planning and Control for Autonomous Landing of Quadrotor Unmanned Aerial Vehicles With Disturbances

Engineering Reports, Volume 8, Issue 9, September 2026.
This paper proposes a trajectory planning method for autonomous landing and designs a disturbance‐compensated nonlinear model predictive controller (NMPC) for environments under wind disturbances. An efficient trajectory planning method based on MINCO is proposed, which transforms the trajectory planning problem into an optimization problem.

Analyzes regarding aviation fuels parameters use on jet engines [PDF]

INCAS Bulletin
The properties of the fuels determine the quality of the combustion process and implicitly the performance of the turbojet engine. The optimal heterogeneous combustion process of an aviation fuel is ensured by a stoichiometric ratio (fuel/fuel), a ...
