4. Student Paper Competition
Each year the IEEE International Frequency Control Symposium conducts a student paper competition. The competition was coordinated by the UFFC Frequency Control Standing Committee Academic Chair, Leo Reindl, with student paper finalists in each of the major technical areas of the symposium being selected by the members of the Technical Program Committees (TPC).
Selection criteria are:
• Student is first author.
• Work is of high quality and done by the student.
• Abstract clearly describes the work and includes results.
• Student has not won the student prize previously.
     This year 20 finalists were selected at the Feb 13, 2012 TPC meeting from 74 submissions. The submissions and finalists were distributed across each of the 6 TPC groups (group 3 and group 5 were combined).
