Welcome to the international (English-speaking) blog of the Department of Computer Science at the University of Helsinki. Our blog invites views on research, education, student life, and other societal themes connected to our computer science fields. The intention is to build a forum as an open window for readers from inside and outside computer science. If you have any good ideas or articles to share on this blog, please feel free to contact us: cs-blog [ät] cs.helsinki.fi.
NODES Seminar and Two Best Paper Awards
In this month's NODES Pizza Seminar, postdoctoral researcher Suzan Bayhan from HIIT gave a presentation about "Energy Efficiency in Cognitive Radio Networks". In brief, a cognitive radio node is capable of changing its communication frequency in order to better take advantage of underutilized parts of the radio spectrum. These changes should not interfere with the primary licensed user of the frequency, and consider a number of factors such as channel changing overhead, network performance, fairness and energy efficiency.
During the seminar, two best paper awards were also announced, both awarded to the Collaborative and Interoperable Computing (CINCO) group.
Lea Kutvonen, Alex Norta and Sini Ruohomaa received the best paper award of EDOC 2012 (the 16th IEEE International EDOC Conference) for their article "Inter-enterprise business transaction management in open service ecosystems". The article proposes and analyzes a two-level business transaction management framework that allows injecting business-level concerns to the technical control processes of inter-enterprise transactions. It received the highest average ratings from reviewers, and was lauded both for the maturity of the work and its evaluation methods, in addition to "making a difficult but relevant problem and an original idea accessible to the reader".
[The IEEE EDOC Conference is the key annual event in enterprise computing. It is a familiar conference for the CINCO group, who received their second best paper award from the series so far. The conference was organized in Helsinki in 2011. It is sponsored by IEEE, IEEE Communications Society and IEEE Computer Society, and is organized in cooperation with ACM, ACM SigApp and ACM SigSoft.
Earlier this year, Puneet Kaur, Sini Ruohomaa and Lea Kutvonen received a best paper award in ACHI 2012 (the Fifth International Conference on Advances in Computer-Human Interactions) for their article "User interface for trust decision making in inter-enterprise collaborations". This article was based on Puneet Kaur's MSc thesis work in the CINCO group, which set out to tackle the problem of presenting a reasonably complex whole of trust, risk and reputation information to a human user making a trust decision in a situation where automated decision-making is not feasible.
When Sini was asked about the ingredients for success for writing best papers, she noted that the common factor for all three papers was that there was a combination of two people working in different disciplines that have a common problem, and Lea as the group leader who has a vision and the means to bring the different ways of thinking together to advance the field - Alex formulated a formal petri net model for inter-enterprise collaboration, while Sini has worked in reputation-based trust management and cites heritage in computer security and distributed systems, and Puneet brought in expertise from the field of usability in particular. At the basis lies a decade of continuous, determined work on supporting inter-enterprise collaborations, so the success was not created overnight.
"Also, you should have fun writing the papers, because it shows."
The NODES seminar consists of presentations within the field of Networking and Services; the next session is scheduled to be on November 9th.
