1.These metallic enclosures attempt to defend the vulnerable electronics inside by forming Faraday cages—sealed conductive boxes that exclude external electromagnetic fields.
2.Sheet-pile quay is adopted in the back of the dock to avoid the bad effect of landside area of high fill soil. The foundation of sheet pile is affected largely by negative friction.
3.Starting from the Kubo-Greenwood formula modified to include ion vibrations under the adiabatic approximation and considering that the low-lying excited normal modes of lattice vibrations are long-wave-length elastic waves, we propose a simple model for phonon-induced electrical resistivity at low temperatures in highly resistive metallic alloys.
