Abstract
We study the effects of dilute random pins on vortex ordering and flow within a bond-diluted Josephson-junction array in a transverse magnetic field. We find evidence suggesting that the disorder drives Tc→0; nevertheless, the flux-flow resistivity in a dc current is reduced compared to a pure array.
