title: Quantitative evaluation of proficiency in rowing with non-contact sensor and assistance of coarching.
abstract: Rowing is a sport using oars to propel a boat on water by one athlete or a crew. High level skills and techniques are required to enable an effective transfer of power through the rowing sequence. However, it is still difficult to coach the crew in real time. Feedback of the rowing is traditionally presented as paper reports or video overlaid with data after the race. In this study, a method is proposed to evaluate the proficiency of rowing quantitatively by measuring the movement of the athlete by setting the ultrasonic and IMU sensors on the boat and oars. An on-board rowing coaching system is also designed to provide auditory or visual feedback to the athlete. In this presentation, the measurement and coaching systems will be introduced. The measurement accuracy is confirmed by testing the measuring system on a rowing machine. language of the presentation: Japanese | |||

title: Estimating Whole Body Motion from Partially Observed Body Motion During Walking
abstract: Measurement of whole body motion using motion capture is useful in various fields. However, it is necessary to mount a large number of markers and sensors, and there are many restrictions on measurement environments. In this research, we propose a method to estimate whole body motion by part of the body motion. Learn a depth neural network that estimates the joint angle of the whole body from some body movements using a database. In the experiment, we compared the estimated joint angle with the motion data and verify the usefulness of the proposed method. language of the presentation: japanese 発表題目: 歩行時における一部の身体動作を用いた全身動作の推定 発表概要: モーションキャプチャを用いた全身動作の計測は様々な分野で役立てられている．しかし，多数のマーカやセンサの装着が必要であり，計測環境の制限も多い．本研究では，歩行動作のデータベースを利用し，身体一部の動作を計測するだけで，全身動作を推定する手法を提案する．一部の身体動作から全身の関節角度を推定する深層ニューラルネットワークを，データベースを用いて学習する．実験では推定された関節角度とモーションデータを比較し，提案手法の有用性を検証する． | |||

title: Study on the influence of torque value of connector on high frequency characteristics of contact boundary surface
abstract: Conventional studies have shown that parasitic inductance increases due to contact failure and increases radiated electromagnetic noise. However, there is not enough discussion between the effect of the change in the torque value of the connector on the surrounding electromagnetic environment has not been sufficient.To investigate the effect, we measure current distributions and electrical responses under varying the torque value of the connector. From the results, we estimate an equivalent circuit in the contact boundary and clear the relationship between torque values and electromagnetic environments. Moreover, we give design guideline of connectors based on the above knowledge. | |||

title: Study on Detection of Electromagnetic Analysis Attack Using Electromagnetic Field inside the Cryptographic Device abstract: Electromagnetic field measurement is difficult to measure without invasion of the electromagnetic field distributed in the space, and in the fields of environmental electromagnetic engineering and measurement engineering measurement investigation is being carried out to minimize invasion of places. On the other hand, at side-channel attacks on a cryptographic module, which have become a new security issue in recent years, an attacker analyzes a secret key by measuring leakage electromagnetic information from a cryptographic module. Countermeasures against such attacks are widely implemented from the algorithm level to the circuit implementation level, but they are individualized for each encryption algorithm, and as for the countermeasure method for fundamentally deterring attacks there is not enough discussion. In this study, focusing on the measurement difficulty of the electromagnetic field, the author develops a system using digital circuit to detect the sign of attack by sampling the electromagnetic field distributed around the cryptographic module from inside the IC, and observing the fluctuation. The author proposes a fundamental countermeasure technique independent of the algorithm developed and implemented. Language of the presentation: Japanese | |||
