SPARS2015 > Program
Program (final)
The
finalized program of the workshop can be found below. The presenting author and title of each oral paper are listed.
TBD = 'to be determined'.
(s) = a paper shortlisted for the 'Best Student Paper Award'. The quality of presentation will be taken into account when the committee are selecting the award-winning paper, which will be announced at the Banquet on 7th July.
All talks will be held in the
Auditorium lecture theatre at Robinson College.
There will be three poster sessions of 2 hours each, during the afternoons of 6th, 8th and 9th July. Approximately 30 posters will be presented at each session according to broad subject groupings, as shown on the
Poster Sessions webpage .
