International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In recent years, learning robot manipulator dynamics with deep networks has been extensively studied, as it avoids deriving the analytical expression of the robot dynamics equations. In particular, deep Lagrangian networks that incorporate the prior knowledge of Lagrangian mechanics into the deep networks have shown prominent advantages in ...

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Understanding solute transport in heterogeneous porous media under variable loading is essential for effective pollution mitigation. However, most existing studies rely on one‐ or two‐dimensional simplifications, limiting their capacity to capture three‐dimensional stress–transport interactions.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The paper presents the modelling of unsaturated soils with the material point method (MPM), including the effect of wetting leading to the loss of strength and the volumetric collapse. The elastoplastic Clay and Sand Model (CASM) extended to unsaturated conditions, formulated in terms of Bishop's stress and suction, has been implemented in an ...

Networks, EarlyView.ABSTRACT We introduce the nested p$$ p $$‐center problem, a multi‐period variant of the well‐known p$$ p $$‐center problem. Using the nesting concept allows us to obtain solutions consistent over the considered time horizon, that is, facilities that are opened in a given time period stay open for subsequent periods.

Underground Freight Transportation for Package Delivery in Urban Environments
Networks, EarlyView.ABSTRACT The use of underground freight transportation (UFT) is gaining attention because of its ability to quickly move freight to locations in urban areas while reducing road traffic and the need for delivery drivers. Since packages are transported through the tunnels by electric motors, the use of tunnels is also environmentally friendly. We examine
