title: Automatic detection of dementia by measuring eye movements
abstract: Recently, the population is aging rapidly, and the number of dementia patients has been increasing. Besides, dementia is progressive and irreversible disease. So, early detection is important. But, because of early detection of dementia is difficult, widely, easily, and quantitative screening tool are required. By the way, according to medical knowledge, dementia patients has visual disorder. Then, I will develop a screening tool that is automatic detecting by measuring eye movements using talk videos. language of the presentation: Japanese 発表題目: 眼球運動計測による認知症の自動検出 発表概要: 近年、高齢化が急速に進展しており、認知症有病者数が増え続けている。 また、認知症は進行性で非可逆の疾患であり、早期発見が重要である。 しかし認知症の早期発見は容易ではなく、広域に、簡便に、定量的にスクリーニングできるツールが必要とされている。ところで、医学的な知見により、認知症患者には視覚への異常が見られる。 そこで私は、高齢者の対話動画像から眼球運動計測により認知症の自動検出を行うツールを開発することを目的とし、研究を行う。 | ||

title: Driving Data Gathering Interface for Route Recommendation of Motorcycle based on Preferences
abstract: Recently, a lot of efficient recommendation technique exist so that it is representative by car navigation. These plan improvement of the comfort by efficiency, but there is little course recommendation technique that attached great importance to entertainment characteristics not efficiency. Therefore I aim at the improvement of the comfort by performing the course recommendation that attached great importance to entertainment characteristics not efficiency. I target the motorcycle user.Because it is thought that the run attached great importance to entertainment characteristics is required. In addition, I built interface to collect run data to estimate the user prererence using a smartphone. It is necessary when I performed course recommendation specialized in an individual. It is intended that I estimate the preferences for the cause in the information of a user provided by the interface that I built in this study. language of the presentation: Japanese 発表題目: 嗜好に基づく自動二輪車の経路推薦のための走行データ収集インタフェースの構築 発表概要: 近年カーナビゲーションに代表されるように効率の良い推薦手法は多数存在する。これらは効率化によって快適性の向上を図るが、効率ではなく娯楽性を重視した経路推薦手法は少ない。そこで、効率ではなく娯楽性を重視した経路推薦を行うことによる快適性の向上を目指す。本研究では娯楽性を重視した走行が要求されると考えられる自動二輪車ユーザをターゲットとする。また個人に特化した経路推薦を行う際に必要となる、ユーザの嗜好を推定するための走行データを収集するためのインタフェースをスマートフォンを用いて構築した。本研究では構築したインタフェースによって得られるユーザの情報を元に、嗜好の推定を行うことを目的とする。 | ||

title: Performance Analysis for transmitting MIMO-OFDM radio signals with 10Gbps OOK signal transmission over optical fiber abstract: Radio over Fiber (RoF) is a fiber-optics technology to transmit radio frequency (RF) signal over an optical fiber using optical carrier. The RoF can transfer analog RF signals over long distance rather than coaxial cable because of the low attenuation property of optical fiber. The RoF is expected to constitute mobile backhaul and fronthaul, access network because of the centralized operation of several base stations such as the Femto cell and small cell in 5G cellular system. A novel configuration of RoF link using optical 10Gbps Ethernet has been proposed. The intensity of optical OOK signal is re-modulated by the electrical RF signal, and directly detected at the receiving side after the transmission of the optical fiber link. Previous study does not touch multiple-input-multiple-output (MIMO) RF signal transmission even though MIMO is becoming common air interface in wireless communication to achieve larger communication capacity than single antenna system. To transmit a MIMO radio signal to remote site over signal optical fiber channel without crosstalk, multiplexing method is required. My research target is to propose the multiplexing schemes for radio MIMO-Orthogonal Frequency Division Multiplexing (OFDM) signals over single optical fiber link shared with the 10 Gbps Ethernet link. I propose a frequency division multiplexing (FDM) based method using subcarrier multiplexing. Theoretical analysis and computer simulation evaluate receiving on-off keying (OOK) signal and MIMO-OFDM signal. language of the presentation: Japanese | ||

title: Autonomous Power Distribution for Parallel Line Fed Wireless Power Transfer abstract: In parallel line fed wireless power transfer (WPT), power delivered to each receiver depends on load impedances and Z-parameters of all receivers in the feeding area. Centralized control for power distribution, which adjusts load impedances of all receivers according to their Z-parameters, is able to adjust the power distribution but suffers from a due to heavy control signaling. To reduce the control signaling burden, this paper proposes an autonomous power distribution in which receiver located closer to the source takes the initiative to adjust its load impedance to autonomously control its received power. Numerical analysis is carried out to confirm the capability of the proposed autonomous power distribution. language of the presentation: Japanese | ||

title: A Proposal of Electromagnetic Coupling for Parallel Line Fed Wireless Power Transfer abstract: In this presentation, we propose electromagnetic coupling for stabilizing the power transfer efficiency (PTE) of parallel line fed wireless power transfer (WPT). The conventional WPT system using magnetic coupled parallel line feeder suffers from PTE fluctuation due to magnetic field standing wave along the feeder line. Focusing on the fact that electric and magnetic fields are out of phase by 90 degrees, we propose a combination of electric and magnetic coupling to stabilize the PTE. In addition, load impedance is also optimized to Z-parameters of the system for further PTE enhancement. Numerical analysis confirmed effectiveness of the proposed electromagnetic coupling in stabilizing PTE for the WPT system. language of the presentation: Japanese | ||

title: A Study of Capacity of 4-by-4 MIMO Channel Using Leaky Coaxial Cables for Linear-cells abstract: Leaky coaxial (LCX) cable is widely used in wireless transmission communication systems as antenna for a long and narrow area called as linear-cell. We have proposed that one single LCX cable can be used as two antennas and the method to utilize one composite cable, which consists of a pair of LCXs with different radiation characteristics, to configure a multiple-input and multiple-output (MIMO) system. In this paper, we will study capacity of the proposed 4-by-4 LCX-MIMO system and compare its capacity with conventional MIMO system using omnidirectional antennas over 2.4GHz band. We also investigate the capacity difference if the spacing of two LCX cable is changed over 5GHz band. The results over 2.4GHz band show that the proposed system can reduce the space requirement for MIMO deployment for wireless application over linear-cell environments. The capacity results show that proposed LCX-MIMO channel has larger capacity than that of using monopole antennas at both sides. Over 5GHz band, the proposed LCX-MIMO channel using water-filling (WF) allocation scheme can have the capacity near to that of $i.i.d.$ channel. It has good channel capacity even if the spacing between the pair of LCXs is as small as 2cm. On the other hand, the capacity can be largely improved using the simple equal power (EP) allocation scheme if the system utilize LCX cables to configure MIMO systems for both 2.4GHz and 5GHz bands. language of the presentation: English | ||
