Effect of the deposition conditions of platinum electrodes on their performance as resistive heating elements

open access: yesMaterials Research, 2004
The performance of different platinum electrodes used as resistive heating elements was studied. Pt films having different thickness were deposited by RF magnetron sputtering at room temperature followed by post-deposition annealing at 700 ºC or made in ...

Conditions, constraints and contracts: on the use of annotations for policy modeling. [PDF]

open access: yes, 2015
Organisational policies express constraints on generation and processing of resources. However, application domains rely on transformation processes, which are in principle orthogonal to policy specifications and domain rules and policies may ...
