Predicting the penetration rate is a complex and challenging task due to the interaction between the tunnel boring machine (TBM) and the rock mass.Many studies highlight the use of empirical and theoretical techniques in predicting TBM performance.However, reliable performance prediction of TBM is of crucial importance to mining and civil projects
ABSTRACTIn the Amazon, river navigation is very important due to the length of navigable rivers and the lack of alternative road networks.Boats usually operate in unfavorable conditions, since there is no hydrodynamic relation Greens among propellers, geometry, and the dimensions of the boat hull.Currently, there is no methodology for propeller hyd
