Figure 6 shows that a non-uniform particle distribution in the cross-section of the tube may occur, even far from the minimum pressure drop points. At the highest air velocity (23 m/s) and the lowest ...

The corruption of the information stored in floating gate cells due to heavy-ion strikes is a critical issue for the use of Flash memories in space. In this work we examine how feature size scaling ...
