Conference Overview
• Theme
– Structures, Structural Dynamics, and
Materials – From Conception to Application
• Speakers
– Industry, Government, Academia,
International?
Conference Overview
• 45th AIAA/ASME/ASCE/AHS/ASC Structures, Structural
Dynamics and Materials Conference
• 12th AIAA/ASME/AHS Adaptive Structures Conference (Greg
Agnes and Lee Peterson )
• There will be two Forums
– Non-Deterministic Approaches (Chris Chamis & Levon
Minnetyan)
– Gossamer Spacecraft (Eric Flint & Rich Pappa)
• TC’s are responsible for:
–
–
–
–
Review of all papers in their area
Preliminary Layout of Sessions
List of names/address/email/phone for Session Chairs & Co-Chairs
Prioritization of each Session (give each session a different priority
number)
– Indicate Plenary Sessions and Student Papers
Abstract Review Procedures & Dates
(Includes SDM, ASC, DSM and Forums)
• Abstract reviews will be handled electronically like
last year
• Abstracts – published due date is 1 Aug 03
• All abstracts get three independent reviews
• Invited vs. encouraged papers – what’s the
difference?
– The only truly invited papers are the Keynote addresses
and the SDM Lecture
– All other papers will go through the standard review
process
• Swapping abstracts with other TC’s or Forums as
appropriate is encouraged (inform the Technical
Chair!)

Structures Review Statistics
Structures Area Abstracts – SDM 45
• Abstracts Processed
– 150 Total Structures Abstracts Submitted
– 0 Accepted (too early to accept/reject)
– 0 Rejected (too early to accept/reject)
– 34 Returned for Revision
– 449 Reviews Assigned
– 162 Completed Reviews
– 37% Total Reviews Completed
• 6 Student Abstracts Placed In Structures Sessions
• 5 Special Sessions in Structures Program
Review Process
• Review Team
– 36 TC Member Reviewers – Average 5 abstracts (will increase)
– 33 Friends of TC Reviewers – Average 5 abstracts
– 33 Volunteer Reviewers – Average 3 abstracts
• 1st Abstract Deadline 8/1/03 - around 90 abstracts
submitted
• 2nd Abstract Deadline 8/15/03 – Shot up to 150 abstracts
• Conducted initial screening and sent 34 abstracts back
for revision
– 19 were revised
– 15 were not revised; (will be rejected)
– If reject 5 more, would give an acceptance rate of 87%
• 430 Now under review
• We are short on reviewers, as I expect some reviewers
not to perform; expect to assign these to other reviewers

End of Presentation
Alternate Abstract Review Process
Based on Materials TC Approach
• Distribute Submitted Abstracts to Small TC Review Team
– Assess Technical Credibility
– Identify Clearly Deficient Abstracts
– Return Deficient Abstracts for Revision With Due Date
• Accept Abstracts That Pass Initial Review
• Reject Deficient Abstracts If Not Revised
• Reject Deficient Abstracts Not Revised Satisfactorily
NOTE
• This Approach Is Fair
– Allows for Revisions to Occur
– Ensures That Authors Who Make An Honest Effort Get
Chance to Present
• This Approach Is More Consistent With the High Acceptance
Rates for Abstracts
