2. TCTF activities since last meeting in Pattaya

At the last TCTF meeting, it was determined to perform a questionnaire to ask (1) opinions on the proposal to change peer reviewer appointment procedure (2) to register potential reviewers if the proposed change is agreed (3) what is required by the institutes in the Developing Economies (4) what can be provided from the supporting side The questionnaire was circulated to the TCTF member institutes in Dec. 2010. 12 NMIs have returned the filled questionnaire. (1) Proposal to change peer reviewer appointment procedure Before : Proposal : Each NMI proposes a peer reviewer to the TCTF chair for approval. Each NMI proposes the name of NMI to the TCTF chair for peer review and TCTF chair appoints a peer reviewer from the registered candidates who belong to the proposed NMI. Agree : 11, Disagree : 0, Abstention : 1

5. Other Activities 1) Special Issue of MAPAN • A special issue of MAPAN (International Journal of Metrology Society of India) on Advanced Frequency Metrology has been planned to be published as a March issue of 2012. • Guest Editors : Y. Koyama (NICT) and A. Sen Gupta (NPLI) • A call for paper has been circulated to the community (APMP TCTF members and URSI GASS 2011 Session Conveners) and two papers have been submitted. 6 more papers are expected. 2) Maintenance of member list on the APMP website • New APMP website has a function to update member list by the TCTF chair (not by APMP secretariat like before). Please send removal, correction, and modification request to TCTF chair. • A new member application can be sent to the TCTF chair from the website. The new member is added to the list upon approval by TCTF chair. It is safer to notify the TCTF chair by e-mail, too.

Matters to be discussed

• Promotion of R&D Activities in the TCTF Community • Possible Technical Supports for Developing Economies • Actions for Future Meetings • New Structure of the TCTF • Guidelines for Uncertainty Evaluations in CMC Tables
