In tunnel excavation with boring machines, the face is supported to avoid collapse and minimise settlement. This article proposes use of reinforcement learning, specifically deep Q-network algorithm, predict support pressure. The algorithm uses a neural network make decisions based on expected rewards each action. approach tested both analytically numerically. By using soil properties ahead ove...

End-expiratory pressure remains one of the few parameters mechanical respiratory support whose values have not been strictly regulated using evidence-based approach. The absence «gold standard» for end-expiratory optimization together with its obvious significant contribution to efficiency and safety has driven search optimal method choosing several decades. Aim review : identify methods determ...
