Editorial: A message from the new editor-in-chief


It is both a great honour and a huge responsibility to serve as the Editor-in-Chief of ECTI Transactions on Electrical Engineering, Electronics, and Communications (ECTI-EEC). Over the past decade, the ECTI-EEC transaction has attained significant accomplishment to be indexed by SCOPUS, Asean Citation Index (ACI) and Thai journal Citation Index (TCI). This is evidently due to the great efforts of former editors, contributing authors, reviewers, and the supporting staff. The new team of editorial committee aim to continue in the same positive direction. We are strongly committed to further improve the quality and service the transactions. We aim to provide an overall professional, timely and helpful engagement with authors and improve the publication turnaround time.

Finally, I warmly welcome any comments or suggestions from authors, reviewers, and all of ECTI members about ways to improve the quality and value of the ECTI-EEC transaction. I am looking forward to working with you all.
