The Community for Technology Leaders

State of the Journal


Pages: pp. 1-5

Welcome to the first issue of 2009 as we begin the 58th year of publication of the IEEE Transactions on Computers(TC); I am delighted and honored to take this opportunity to review with you the activities and endeavors that were undertaken in 2008 as well as the ones planned for 2009.

Last year, TC further consolidated its standing among our community-at-large. For the calendar year 2008, the total number of manuscript submissions (inclusive of Special Sections) stood in the 600 to 650 range, very near its historical peak (with an acceptance rate just above the 25% mark); as a measure of overall timely review, the delay encountered from submission to first notification has been decreased to just 93 days. I congratulate all constituencies for these remarkable accomplishments; the ingredients of this success can be found in the dedication and the unabated and continued quest for excellence as delivered to the readership by the authors, the reviewers, the Associate Editors, and the Computer Society staff.

TC continues to be published on a monthly basis and, for 2008, the number of published pages saw only a modest increase as a reflection of a rigorous review process; nevertheless, coverage of the 2008 issues encompassed different Special Sections (the names of the Guest Editors are provided in parentheses) on disparate topics such as Networks-on-Chip (September 2008, R. Marculescu), Programming Architectures for Embedded Systems (October 2008, S.K. Shukla and J.-P. Talpin), and Special-Purpose Hardware for Cryptography and Cryptanalysis (November 2008, R Steinwandt, W. Geiselmann, and K.C. Koc).

2009 promises to be yet another resounding year. The number of manuscripts currently under review suggests that TC will continue to meet its mandate to the readership by accommodating, in a monthly issue, regular papers as well as a variety of Special Sections over the whole year. I expect the publication delay to be further reduced as electronic delivery is aggressively pursued once all material for each accepted manuscript is received by the Computer Society. The following Special Sections are currently being processed for publications in the year ahead: Computer Arithmetic (P. Kornerup, P. Montuschi, J.-M. Muller, and E. Schwarz), Emerging Technologies (Y. Makris, P. Mazumder, and A. Benso), Autonomic Network Computing (D. Avresky, D.C. Verma, and H. Prokop), and System Level Design of Reliable Architectures (C. Bolchini and D. Sciuto).

I invite you to visit the TC web site at to ensure that you will be able to contribute to the in-depth coverage offered by Special Sections. Special Sections offer an unique opportunity to publish state-of-the-art manuscripts within a focused presentation edited by leaders from industry and academia.

During 2008, the Editorial Board of TC has seen the retirement of the following Associate Editors at completion of their appointments: J.C. Bajard, T. Brun, F. Dehne, M. Dubois, A. Schuster, and A.M. Gonzalez. I would like to take this opportunity to commend them for a superb job and I look forward to their continued involvement and participation in all aspects of TC, as great AEs are also eminent scholars.

The new members of the Editorial Board have been carefully selected through an extensive selection process; the appointments of the following colleagues have been approved by the Computer Society: C.A. Gunter, R. Marculescu, P. McDaniel, P. Montuschi, N. Ranganathan, E. Schwarz, H. Shen, and S. Shukla.

I am excited to work with them and to further provide you with the best service and share the expectation to meet the challenges in our future endeavors. Do not hesitate to contact me for any enquire related to TC; your comments and suggestions are always welcome. I look forward to yet another successful year and, as in the past, we heartily solicit your contributions.

He is currently serving on the President’s National Security Telecommunications Advisory Panel, counseling on public policy for security and best practices in evolving cellular networks. He has worked directly with the FCC and the FBI in understanding the nature of vulnerabilities and their effects in telecommunication networks. He has also worked with the Department of Homeland Security and industry as a participant in the SPRI program and within the EMIST/DETER project to understand and develop practical solutions for securing global network routing. He was named the principal investigator of the EVEREST project analyzing the security of voting systems used in Ohio. Working directly with the Ohio Secretary of State and leading teams from Penn State, the University of Pennsylvania, and the University of California-Santa Barbara, he directed source code and red-teaming efforts used to illuminate security issues in voting systems and to assess the effectiveness of technical and procedural countermeasures addressing flaws.
