      ＜Your impression & future plan＞
      We, the co-authors of Flower Jelly Printer, are all very proud of this award. Considering a better way to demonstrate our work for CHI that took place online due to the COVID-19 pandemic led to the award. We believe our research will enhance the freedom of food and help achieve an inclusive society where diverse people can join cultural and economic activities. We will keep on working on proof-of-concept experiments for improvement and commercialization of our technology.

    • Kentaro Matsuura, D1, Department of Electrical Engineering and Information Systems, Graduate School of Engineering, received IEICE Technical Committee on Wireless Power Transfer: Young Researcher Award.

      ＜Name of award and short explanation about the award＞
      IEICE Technical Committee on Wireless Power Transfer: Young Researcher Award

      Young Researcher Award is given to presenters under the age of 33 who present excellent papers in the regular workshops of IEICE Technical Committee on WPT.

      ＜About awarded research(activity)＞
      Kentaro Matsuura, Daisuke Kobuchi, Yoshiaki Narusue, and Hiroyuki Morikawa, "Communication-Less Receiver-Side Resonant Frequency Tuning for Wireless Power Transfer Using Magnetic Resonant Coupling, " IEICE Technical Report, WPT2020-26, Dec. 2020.

      Magnetic resonant coupling wireless power transfer is expected to be applied to recharge electric vehicles and mobile devices since it can provide highly efficient power over a transmission distance of up to approximately 1 meter. However, the presence of metal, water, etc. in the vicinity of the power receiver causes the resonance frequency of the power receiver to change, resulting in a decrease in the efficiency of wireless power transfer. In this study, we have developed a communication-less receiver-side resonant frequency tuning mechanism that cancels out the effects of resonant frequency fluctuations using a variable reactor composed of purely electronic components. We have realized a wireless power transfer system that enables highly efficient and stable power transfer even under less than ideal operating conditions.

      ＜Your impression & future plan＞
      I am very pleased to receive this honorable award. For the widespread use of wireless power transfer systems, I believe that it is necessary to enable stable power transfer in any environment. In the future, I would like to demonstrate the effectiveness of our proposed method in applications that are more in line with actual settings.

    • Ryoma Kondo (D3), Takashi Ubukata (D2), Kentaro Matsuura (D1), and Hirofumi Ohzeki (M2) received Best Performance Award at ITU AI/ML in 5G Challenge Global Round in Japan.

      ITU AI/ML in 5G Challenge, conducted by ITU, the International Telecommunications Union, is an international competition to solve 5G network problems with machine learning. In the Japan round the Best Performance Awards were presented to the top three teams that qualified as finalists.

      ＜About awarded research＞
      Autonomous detection of faults within the Internet core network, which is interoperable between internet service providers, is required for high-quality 5G networks. It is difficult to find effective features in a wide range of time-series data and to manage routing path logs in machine learning. We therefore developed a failure detection method based on an effective selection of features using entropy and semantic interpretation of routing information using natural language models.
