A video is composed of rendered elements such as text, audio, and visual elements. It may convey messages that emotionally engage viewers via embedded elements that demand visual attention, referred to as Visual Markers (VM). However, little attention has been paid to VM, particularly in terms of determining which VM influences viewers’ emotional experience. Lack of understanding of VM and its impact on viewers’ emotional experience may result in negative impact and hamper efficient video classification and filtering. This is crucial when, for instance, a YouTube video is used for malicious agenda. To fill this gap, this research was conducted to identify VM in Extremist YouTube Videos (EYV). It is helpful in determining significant viewers’ emotional responses upon watching EYV, and to develop an affective classification model based on emotional User Experience (UX) and VM in YouTube videos. The research conducted in Kansei evaluation using 20 YouTube video specimens with 80 respondents. Multivariate analysis was performed to determine the structure of emotions, the relationship between a VM and emotional responses, and classify the emotional responses and influential VM. The result has enabled this research to develop an affective classification model comprising three emotional dimensions; offensive, intrigue and awkward. The model contributes a new understanding of the body of knowledge of emotional evocative video elements and provides insights to authorities, policy makers, and other stakeholders to manage the classification of emotional evocative video. It could be used as a basis for formulating an algorithm to filter video content. Although the model was based on work under certain limitations, they lend some novelty by linking affect to VM in video classification. Future work could explore enhancing its applicability using wider scope and population of subjects and instruments. Additionally, video producers could extend the model in producing videos capable of invoking a targeted emotion to the viewers.

Remotely monitored and operated unmanned vessels are effective for the working environment improvement of vessel crew, the solution of crew shortage, and the efficiency of marine survey. However, the development of unmanned vessels is delayed. One of factors is the communication problem. A bit rate of the current maritime communication using the satellite communication is about several hundred kbps from vessels. Therefore, this bit rate is insufficient for remote monitoring and operation. To solve this problem, a use of a long-range Wi-Fi communication is proposed. In this paper, the unmanned system capable of remote monitoring and operation with long-range Wi-Fi is developed and examined at Tokyo bay.

Long time behavior of one-dimensional self-gravitating system is numerically investigated. Itinerant behavior among quasiequilibria is discovered, and its origin is clarified. The macroscopic distributions of the quasiquilibria are different from the isothermal distribution, but the transient states, which appears between two successive quasiequilibria, resemble the isothermal distribution. Averaging over the is itinerancy gives approximately the thermal equilibrium.

Dynamical evolution of galactic disks driven by interaction with satellite galaxies, particularly the problem of the disk warping and thickening is studied numerically. One of the main purpose of the study is to resolve the long standing problem of the origin of the disk warping. A possible cause of the warp is interaction with a satellite galaxy. In the case of the Milky Way, the LMC has been considered as the candidate. Some linear analysis have already given a positive result, but one had to wait for a fully self-consistent simulation as a proof. I have accomplished the numerical simulations with a million particles, by introducing a hybrid algorithm, SCF-TREE. Those simulations give us quantitative estimates for the Milky Way system. We have found an example in which large warp amplitudes are developed. We also found that the warp amplitudes depend on the halo distribution. Among our three models, the most massive and spherical halo is preferable for the observable warp excitation.

Kansei Engineering is advanced method for analyzing the relationship between design elements and human images at the designing production design. Nonlinear relationships among evaluation data used by Kansei Engineering system are discussed in this paper for the purpose to consider the distribution of Kansei data. The analysis of real products extract the nonlinearity in the data of SD scaled questionnaire. In especially, treating combination effects among design elements are very difficult problem to solve in kansei analysis. Then we discuss the analysis the combination effects at kansei evaluation data.

In this study, Lnx(SiO4)6O(1.5x−12) (Ln: Nd, La) materials as electrolytes for solid oxide fuel cells (SOFC) were prepared by the sol-gel process. It has been reported that the apatite structure of Lnx(SiO4)6O(1.5x−12) shows higher ionic conductivity than yttrium-stabilized zirconium oxide at the working temperature of the SOFC. Ln10(SiO4)6O3 is a major component of the Lnx(SiO4)6O(1.5x−12) system. Ln10(SiO4)6O3 consists of Ln9.33(SiO4)6O2 and a small amount of Ln2SiO5. It has been proposed that the ionic conductivity of Lnx(SiO4)6O(1.5x−12) decreases with increasing Ln2SiO5 with non-apatite structure. The object of the present study was to bring about this decrease by generating Ln2SiO5 in the system.Precursor solutions for synthesis of the powder were prepared using tetraethoxysilane (Si(OC2H5)4) and neodymium acetate monohydrate (Nd(CH3COO)3·H2O) or lanthanum acetate monohydrate (La (CH3COO)3·H2O) as raw materials and acetic acid (CH3COOH), 2-methoxyethanol (C2H5OCH2CH2OH), and triethanolamine (N(CH2CH2OH)3) as solvents. To obtain the powder, the solution was dried and heat-treated at 600 °C for 2 h. Disks made from the powder were heat-treated at temperatures between 1100 and 1500 °C for 10 h. The results of an XRD investigation indicate that almost all diffraction peaks of these samples could be assigned to Ln9.33(SiO4)6O2. The sample with x = 10.00 included a small amount of Ln2SiO5. The ionic conductivity of this latter sample was higher than that of other samples with similar values of x (x = 9.33 and 10.67).

Organic-inorganic hybrid lithium ion conductors were prepared by the sol-gel process. The hybrid ion conductor will be used as the electrolyte for Li based high-energy density batteries. The hybrid ion conductor was prepared from a mixture of tetramethyl orthosilicate (TMOS), polyethylene glycol 200 (PEG200), lithium perchlorate (LiClO4) and water. A wet gel was prepared at room temperature. The gels dried at 80°C under vacuum did not contain water. The dried hybrid ion conductor gel had homogeneity and high transparency. Ionic conductivity of the hybrid sample was measured by the complex impedance method and it increased with increasing PEG200 content. The dried hybrid gel that contained no LiClO4 did not show ion conduction. Conductivity on the order of 10−5 S·cm−1 at room temperature was obtained. Structural characterization was done by Fourier Transform Infrared Spectra (FTIR) and NMR measurement of 13C and 1H, and the thermal stability and glass transition properties were studied by DSC. Glass transition temperature decreased with increasing PEG200 content and increased with increasing [Li]/[O] ratio (the oxygen considered is from the polyethylene glycol). Existence of the Si–O–(C2H4O)n–bond and the C–OH bond in the framework of the organic and inorganic phases was confirmed. TMOS and PEG200 were hydrolyzed and condensed. The organic and inorganic phases were chemically bonded and the microstructure of the hybrid matrix was shaped as comb. The comb shape leads to high ionic conduction.

In this study, we prepared SrxBa1 − xNb2O6 (x = 0.3, 0.5 and 0.7) thin film on 0.75 wt% La doped SrTiO3 (100) and (110) single crystal substrates. A homogeneous coating solution was prepared with Sr and Ba acetates and Nb(OEt)5 as raw materials, and acetic acid and diethlene glycol monomethyl ether as solvents. The substrates were coated with the solution by spin coating method. As-coated thin films were heated from 973 to 1273 K in air. The grains of the thin film on La doped SrTiO3 (100) were pillar shaped and arranged in right angle to each other. On the other hand, the grains of these thin films on La doped SrTiO3 were pillar shape and arranged in one direction. The crystallographic relationship of the thin film between SrxBa1 − xNb2O6 and substrate that the 〈130〉 and 〈310〉 direction of the thin film on the substrate were oriented with c-axis in parallel to the substrate surface. On the other hand, (hk0) phase diffractions of SrxBa1 − xNb2O6 thin film on the substrate (110) were investigated in the XRD theta-2theta measurement. It is expected that the SrxBa1 − xNb2O6 (x = 0.3, 0.5 and 0.7) were highly oriented or epitaxial growing on La doped SrTiO3 (110) single crystal substrate.
