title:Single-trial ERP Analysis Using Varying Covariance Modeling in the Time-Frequency Domain
abstract: Event-related potentials are usually analyed via synchronous averagingof multiple trials to cancel out background EEG activities which sacrifices information about each single-trial. Hence, we developped a noise removal technique to realize single-trial ERP analysis using covariace matrix varying local Gaussian modelingin in the time frequency domain. We performed simulation study to validate our proposed method using a realistic head and source model and found our method estimate time cources of single-trial ERPs more acculately than compared convenional methods. We also found a method using spatial covariance matrices were better than independent one. language of the presentation: Japanese | |||

title: Common neural representations of anxiety from whole brain functional connectivity abstract: Although we all know anxiety, we do not know whether our anxieties are the same each other, or at least having common elements among them. Here, we investigated the common neural representations of anxiety among the different task conditions and participants’ populations in a unified analytical framework using functional connectivity magnetic resonance imaging (fc-MRI). Through the anxiety provocation task, we found common anxiety related neural networks among participants. Then, using the resting state fc-MRI from the Human Connectome Project, we demonstrated that the task-independent brain also shared networks with the task-dependent anxiety. Furthermore, the overlapped networks among task-dependent and task-independent brain could detect the abnormal neural representations of patients with obsessive-compulsive disorder, which is characterized by the repeated anxiety-driven behaviours. Our findings indicate the common neural representations of anxiety captured by whole brain functional connectivities across individuals, trait/state features and populations. language of the presentation: Japanese | |||

title: Improving the Accessibility of High-Quality Gaming using the technology of Cloud Gaming abstract: The emerging Cloud Gaming Service provides highly accessible video gaming experience. However, compared to traditional gaming, there is still an obvious gap in term of delivered gaming quality because of the network constraints. Furthermore, the versatility of Cloud Gaming system also represents a potential platform to improve the accessibility of some novel gaming that is on trend. Therefore, in this research, from two aspects, we aim at improving the accessibility of high-quality gaming based on the technology of Cloud Gaming. For the first aspect, we propose a hybrid streaming method for improving the graphic quality delivered on cloud gaming. The proposed method utilizes both the rendering power at server side and client side to achieve the desired improvement. The performed quantitive evaluation shows that our proposed method achieve better graphic quality than traditional Cloud Gaming system as well as mitigating the server workload. As for the second aspect, since the novel VR gaming requires expensive local setup to maintain smooth gaming experience, we consider to apply cloud gaming technique to improve the accessibility. The main challenge is to maintain a fast responsiveness throughout the system, as VR gaming needs even more rapid response time than traditional gaming. For this reason, for applying the current Cloud Gaming system to VR gaming, we are planning to apply techniques such as head-motion prediction, eye tracking to efficiently mitigate the response time. language of the presentation: English | |||

title: Inductive Power Transfer System Using Multiple Concatenated Parallel-Line-Feeder Segments
abstract: It has been known that the dimensions of the primary coil of an inductive power transfer (IPT) system need to be smaller than approximately one-tenth of a wavelength to avoid impact of standing wave. Recently, an IPT system of concatenated parallel-line-feeder segments has been proposed to overcome this limitation. Numerical analysis in literatures has showed that the system is capable of providing a stable output profile regardless of the length of the primary coil. In this study, the stability of output power of the system is verified via experiment systems at 13.56MHz. language of the presentation: English | |||

title: sliding motion using a multi-copter with a lightweight manipulator
abstract: Multi-copters are expected to be active in rescue and inspection in the high place. Though aerial manipulation using multi-copters has being done, there are still some problems with stabilization control. Cleaning windows is one of the examples of aerial manipulation. Cleaning the windows needs to be done in high place, and conventional approaches which done by a specific machine and humans are expensive and dangerous. So, this study provides a system that cleans windows using multi-copters with a manipulator. Specifically, a sliding motion for cleaning windows is performed by one DoF manipulator mounted on a multi-copter. The multi-copter keeps the contact force constant by controlling the manipulator, and controls its orientation in order to keep the orientation of the manipulator. By making them each independently, this system becomes simple and could achieve the stable sliding motion. language of the presentation: Japanese 発表題目: 軽量マニピュレータを搭載したマルチコプターによる倣い動作 発表概要: 災害救助や高所での点検などの分野において，マルチコプターの活躍が期待されている． マルチコプターによるマニピュレーションの研究も行われているが，マルチコプター自体の姿勢制御が困難なことが問題としてあげられる． マルチコプターによるマニピュレーションの例としては、窓の掃除がある． 窓の掃除は，高所での作業であり，従来の手法では，コストの大きさや作業者の転落の危険などが問題とされてきた． そこで，本研究ではマニピュレータを搭載したマルチコプターを利用して窓掃除を行うシステムを提案する． 具体的な方法としては，マルチコプターに１自由度のマニピュレータを搭載して窓掃除のための倣い動作を行う． 搭載した直動のマニピュレータを稼働させて窓との押し付け力を一定に保ち，これによって動いたマニピュレータの姿勢を保つためにマルチコプターの姿勢を制御する． 押し付け力と姿勢制御を独立に設計することで各々の制御が簡単になり，安定な倣い動作を生成することを狙う． | |||

title: Analytical Model for Transaction-Confirmation Time of Bitcoin
abstract: When we transmit or receive bitcoin with someone, remittance information is included in a transaction. Transactions are grouped into a block, and the block is confirmed by the confirmation process called Mining. However, the block size is limited, and this causes a large transaction-confirmation time when the transaction-arrival rate increases. We analyze the transaction-confirmation time using a single-server queue with bulk service. Numerical examples show how the bulk size affects the transaction-confirmation time. language of the presentation: Japanese | |||

title: Design of prediction governors for nonlinear systems
abstract: In the conventional tracking control of dynamic system, it is assumed that the target value is known. However, an accurate target value may not be available in some cases. In this case, although it is necessary to predict the target value, but when it includes uncertainty, the control performance is deteriorated. In the previous research, a signal shaping mechanism called prediction governors has been proposed, and it is possible to approximate the ideal output by shaping a poorly predicted value. However, the prediction governors cannot be applied to nonlinear systems. Therefore, in this research, we propose nonlinear prediction governors that nonlinearly extends the class of prediction governors. In this presentation, we explain the design problem and derived solution of the nonlinear prediction governors. Moreover, evaluate performance by simulation. language of the presentation: Japanese 発表題目: 非線形システムに対する予測ガバナの設計 発表概要: 従来の動的システムのトラッキング制御において，目標値が既知であることを前提としているが，正確な目標値が利用できない場合がある．このとき，目標値を予測する必要があるが不確かさを含む場合，制御性能が低下する．先行研究では，予測ガバナと呼ぶ信号整形機構が提案されており，精度の悪い予測値を整形して理想の出力に近づけることができる．しかし，予測ガバナでは非線形システムに適用することが出来ない．そこで，本研究では予測ガバナのクラスを非線形に拡張した非線形予測ガバナを提案する．本発表では，非線形予測ガバナの設計問題および導出解について説明する．また，シミュレーションを通して性能の評価を行う． | |||
