Derivation of near-optimal pump schedules for water distribution by simulated annealing [PDF]

open access: yes, 2004
The scheduling of pumps for clean water distribution is a partially discrete non-linear problem with many variables. The scheduling method described in this paper typically produces costs within 1% of a linear program-based solution, and can incorporate ...

Thermal annealing of fission tracks in synthetic apatites [PDF]

open access: yes, 2010
Synthetic analogues of poor-silicated natural apatites have been doped with uranium. These minerals have been irradiated with a thermal neutron dose in the aim to induce the 235U fission and to obtain a fission track population.

Modelling the growth of ZnO thin films by PVD methods and the effects of post-annealing [PDF]

open access: yes, 2013
Results are presented for modelling of the evaporation and magnetron sputter deposition of Zn onto an O-terminated ZnO () wurtzite surface. Growth was simulated through a combination of molecular dynamics (MD) and an on-the-fly kinetic Monte Carlo (otf ...

Deposition and Characterization of Antimony Tin Sulphide using Spray Pyrolysis [PDF]

open access: yesPhysics Access
Spray pyrolysis is a method commonly used in aerosol processes for atomizing chemical precursors into aerosol droplets ready for dispersion in gas mediums to form thin films on passing through a hot reactor and getting evaporated.
