DOI: 10.1016/j.jde.2018.07.048
Abstract: Abstract We identify sub-thresholds for finite time shock formation in a class of non-local conservation law with concavity changing flux. From a class of non-local conservation laws, the Riccati-type ODE system that governs a solution's… read more here.

DOI: 10.1111/gwat.12553
Abstract: Introduction Groundwater-flow models are often calibrated using a limited number of observations relative to the unknown inputs required for the model. This is especially true for models that simulate groundwater–surface water interactions. In this case,… read more here.

DOI: 10.3390/polym13121919
Abstract: Many theoretical analyses of extrusion ignore the effect of the flight clearance when predicting the pumping capability of a screw. This might be reasonable for conventional extruder screws with “normal” clearances but leads to errors… read more here.
