The principal goal of this project is the correct characterisation of the thermophysical properties of phase change materials (PCMs) in order to have reliable

Also, if the residual off time distribution converges in time then the optimal policy converges to the constant policy and in fact becomes constant after finite time (under

This method enables shape description with a controlled ac- curacy, and the generation of new sets of grains, that are morphologically equivalent to real ones, as regards

To address these issues, we explore the seismic properties of granulometric end-member-type clastic sedimentary seabed models consisting of sand, silt, and clay as well

Electrons passing through the target are deflected back towards the target by the surrounding electric and magnetic fields, increasing the electron density and

In the following, changes in void ratio and pore size under compression were examined in order to better understand soil suction and threshold stress variations in relation
