The workshop will include an introductory session, technical sessions devoted to presentations by participants on the topics outlined in the objectives and a final session. The final session will summarise the discussions and compile conclusions and recommendations for possible further actions by the CSNI. All participants are expected to take part in the discussion and in the formulation of conclusions in the final session.
Papers and case studies addressing the issues mentioned in the objectives of the workshop are welcome. Several sessions with ample time for discussion will be allocated to these topics.
