Conference Overview
  • 45th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference

  • 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 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!)
latest planning schedule

review process
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

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
