○International Award
Mr. Tomohiko NAKAMURA (Student Member)
He was born in Hiroshima, Japan in 1989. He received the B.Sc in Information physics from university of Tokyo in 2011. He is a student of Department of Information Physics and Computing, Graduation School of Information Science and Computation in the University of Tokyo. He is a SICE student member.
受賞論文「Local Stability Analysis for a class of Quorum-Sensing Networks with Cyclic Gene Regulatory Networks」
Quorum-Sensing (QS) is one of cell-to-cell communication mechanisms of bacteria. The dynamics of QS network essentially involves reaction dynamics of gene expression. In this paper, we analytically derive local stability/instability conditions for a class of QS networks with cyclic gene regulatory networks. These conditions shed light on two important biological facts on local stability of the QS network. We clarify three essential parameters, and show a relationship between gene networks and QS networks for local instability.
Dr. Kenji KASHIMA (Member)
He was born in 1977 in Oita, Japan. He received his M.Sc. and Ph.D. degrees in Informatics from Kyoto University in 2002 and 2005, respectively. From 2005 to 2011, he served as an Assistant Professor of the the Graduate School of Information Science and Engineering, Tokyo Institute of Technology. From April 2010 to March 2011, he was at Stuttgart University as an Experienced Researcher of the Alexander von Humboldt Foundation, Germany. Since October 2011, he has been with the Graduate School of Engineering Science of Osaka University, where he is currently an Associate Professor. His research interests include mathematical theory for distributed and stochastic phenomena in large scale (possibly infinite-dimensional) dynamical systems, as well as its applications .
受賞論文「Connection Profile Robustness in a Heterogeneous Network of Piecewise Affine FitzHugh-Nagumo Models」
FitzHugh-Nagumo is one of the best known nonlinear neuronal models in mathematical physiology. In this paper, we investigate the stability of diffusively coupled large-scale networks of piecewisely affine approximated FitzHugh-Nagumo models. Scalable criteria for ultimate boundedness are given taking connection profile robustness (coupling strength, delay length, subsystem heterogeneity) into account. The efficiency is demonstrated by a simple cardiac action potential model.
○Young Author's Award
Mr. Akihiro CHIBA (Student Member)
He received the bachelor degree in engineering from the University of Electro-Communications, Tokyo, Japan, in 2011. He is currently a graduate student for master's degree at Department of Mechanical Engineering and Intelligent Systems, the University of Electro-Communications, Tokyo, Japan. His current research interests include localization of an RFID tag and tabletop interfaces.
受賞論文「Two-dimensional Localization of an RFID Tag by Using a Weighted Integral Sensor on a Square Boundary」
This paper presents a novel method for localization of a passive Radio Frequency Identification (RFID) tag in two-dimensional (2D) space. First, we show that a line on which the RFID tag exists in a 2D square domain can be estimated from the weighted integrals of the magnetic field created by the tag along the boundary of the domain. Then, for measuring them, we develop a square-shaped magnetic sensor composed of three coils only: two pairs of oppositely-wound rectangle coils connected in series on the parallel sides of the square domain, and four bow-tie-shaped coils connected in series on all sides.
Using the developed sensor with the side length of 200 mm, a low frequency (135 kHz) RFID tag was localized in the square area 160 mm on a side with the average error 5.9 mm at 80 points. |
