Overview of rocket engine control [PDF]
AIP Conference Proceedings, 1992 This paper broadly covers the issues of Chemical Rocket Engine Control. The basic feedback information and control variables used in expendable and reusable rocket engines, such as the Space Shuttle Main Engine are discussed. The deficiencies of current approaches are considered and a brief introduction to Intelligent Control systems for rocket engines

Iron‐Based Catalysts for the Removal of Microplastics
Advanced Energy and Sustainability Research, EarlyView.Microplastics (MPs) are some of the newer environmental dangers and are still in need of optimal treatment. Iron‐based compounds can be used as catalysts for the removal of MPs due to the iron abundance, sustainability, and catalytic versatility. This review presents the current status of iron‐based materials for the photocatalytic, Fenton process, and

Real‐Time and Rapid Dynamic Missile Identification Utilizing a TiOx Memristor Array
Advanced Intelligent Systems, EarlyView.Real‐time missile target identification is demonstrated using an artificial intelligence model based on step‐weighted long–short‐term memory networks and a TiOx memristor array. The approach classifies five projectile types with enhanced early‐stage prediction through data augmentation and custom training strategies. Achieving 94.4% accuracy, the model
