This article contributes to the realization of an immersive role playing manga generating advertising system named \Manga Generator". The project began as a student virtual reality project and had underwent various collaborations with professional manga artists and governmental agencies. It was exhibited at many international exhibitions and is currently a permanent exhibition in a museum. The latest version \MGV" is a new advertising entertainment system that enables up to two players to engage in role playing in- teractive manga while allowing other audiences to see adver- tisement video simultaneously using multiplex hidden image technology "ExPixel". In this research, we combined inter- active comic generating system with full body motion de- tection and real time image processing technologies. It can attract non-audiences who are not interested in the video an- nouncements thanks to players playing Manga Generator. © 2016 ACM.

A scheme is proposed for generating multiphase oscillatory signals in millimeter-wave frequencies based on the dynamics of a traveling pulse developed in a closed transmission line periodically loaded with resonant-tunneling diodes (RTDs) that is coupled with several straight RTD lines. When supplied with an appropriate voltage at the end of an RTD line, a pulse edge is shown to exhibit a spatially extended limit-cycle oscillation on the line. We consider the case where several RTD lines are connected halfway to a closed one at even intervals. In this case, the oscillatory edge developed in each straight RTD line is mutually synchronized such that a pulse-shaped rotary traveling wave develops on the closed RTD line. The oscillating edge on each straight line is also synchronized with the traveling pulse on the closed line, such that the leading edge of the traveling pulse on the closed line and the forward edge on the straight line pass the cross point simultaneously. As a result, when NL straight lines are connected to the closed line, the phase difference between two adjacent oscillatory edges becomes 2π/NL. On the other hand, the trailing edge of the traveling pulse at the cross point breaks the voltage wave on the straight line into two pieces, one of which travels forward to form a solitary wave and the other of which travels backward to reach the input end, where it is reflected and starts to travel forward and this forward moving edge is supposed to be synchronized with the leading edge of the traveling pulse. It means that a back-and-forth edge and a forward-moving solitary wave develop periodically on each straight line. Because the time required for the traveling pulse to go around the closed line must be coincident with the period of the edge oscillation on each straight line, a unique traveling pulse cannot synchronize with each oscillating edge when the cell size of the closed line becomes large, resulting in the development of multiple traveling pulses on the closed line. In this paper, the design criteria are discussed concerning the connecting point between the straight and closed lines, the number of straight lines, and the size of the closed line. In addition, we describe several measurement results that validate the essential properties of the traveling pulse and then show several results of full-wave analysis of a monolithically integrated RTD line. © 2017 Springer Science+Business Media New York

This paper presents the input shaping technique for reducing the vibrations of flexible structures under attitude control inputs applied to the flexible spacecraft. The input shaping profile is investigated for the effective suppression of transient vibrations of modal responses. It is applied to the input commands to minimize the residual vibrations and suppress the overshoot of the modal responses. The results of numerical simulations, using a simple dynamic model of a flexible spacecraft, show that the input shaping technique is useful for suppressing the residual vibrations caused by attitude maneuvers. © Published under licence by IOP Publishing Ltd.

To reduce the risk of injury to an infant in an in-car crib (or in a child safety bed) collision shock during a car crash, it is necessary to maintain a constant force acting on the crib below a certain allowable value. To realize this objective, we propose a semi-active in-car crib system with the joint application of regular and inverted pendulum mechanisms. The arms of the proposed crib system support the crib like a pendulum while the pendulum system itself is supported like an inverted pendulum by the arms. In addition, the friction torque of each arm is controlled using a brake mechanism that enables the proposed in-car crib to decrease the acceleration of the crib gradually and maintain it around the target value. This system not only reduces the impulsive force but also transfers the force to the infant's back using a spin control system, i.e., the impulse force acts is made to act perpendicularly on the crib. The spin control system was developed in our previous work. This work focuses on the acceleration control system. A semi-active control law with acceleration feedback is introduced, and the effectiveness of the system is demonstrated using numerical simulation and model experiment. © Published under licence by IOP Publishing Ltd.

JEDI ACE aims to provide an innovative concept of an integrated ice protection system: an inte-grated approach, consisting of combined passive anti-icing coating, active de-icing devices and ice sensors. The system will be applicable to aircraft wings and will support an important technological milestone: the composite wing concept, which today includes also morphing properties. The JEDI ACE consortium, consisting of European and Japanese partners, determined three technical objectives for the integrated ice protection system: 1. An active de-icing device based on electro-thermal and/or mechanical actuation, combined with supporting passive anti-icing coatings 2. An ice sensor system for real-time measurements of ice accretion on aircraft structures, 3. An integrated ice protection system with complementary components for excellent operation properties. The work in JEDI ACE will result in validated design concepts and lab-scale prototypes for the future generation of integrated ice protection systems. The design will contribute to: prevention of ice buildup on leading edges, improved in-flight ice assessment, improved aircraft safety reduced energy consumption during de-icing procedures, reduced de-icing procedures on ground, compliance with design constraints of composite wings including morphing properties, compliance with bleed-air free engines and all-electric aircrafts, compliance with other surface and coating requirements like resistance against erosion The JEDI ACE consortium will develop evaluation devices for all determined objectives on the basis of newest scientific knowledge, combined with appropriate test sessions to validate the performance of the components and deliver the design concept of an integrated ice protection system. This ambitious goal will be achieved by combining the specific SoA competencies through close multinational collaboration.

To study electron states and magnetism in Gd-doped EuO theoretically, we first calculate the spin-polarized density of states (DOS) by applying the dynamical coherent potential approximation (dynamical CPA) for two simple models: the s-f model of electron-doped EuO and a model of Eu 1-xGd xO. On the basis of the spin-polarized DOS, we calculate the total energy of electrons interacting with f spins through an exchange interaction. Then, we obtain the magnetization as a function of the temperature T, by minimizing the free energy. We discuss the mechanism of the electron-induced increase in the Curie temperature T C, the origin of the anomalous magnetization curve, and the existence of a threshold Gd concentration for increasing T C. We investigate the effect of on-site attractive potential that yields an impurity level when the Gd concentration is low. We also discuss the relationship between the redshift of the optical absorption edge and the increase in the T C of Gd-doped EuO. © 2012 American Physical Society.

Many kinds of lactose derivatives can be obtained using various methods, including epimerization, oxidation and reduction. Investigations of the beneficial functions of lactose derivatives developed have resulted in them being put into practical use in numerous fields. In particular, lactulose, galacto-oligosaccharide and lactitol are used in foodstuffs and pharmaceuticals, and new lactose derivatives such as epilactose and tagatose have also recently received attention. Various physiological effects that lactulose exerts have been studied, including the beneficial promotion of bifidobacteria proliferation in the intestine. © 2011 Elsevier Ltd.

An agent-based modeling and the simulator for evacuation from multistory buildings at the time of outbreak of an earthquake and the fire are presented. The basic theory is that individual agents move in each floor and stair, unless it is filled to capacity per unit area. The simulator can reflect the situation when some destruction occurred in a passage and the stairs in the middle of refuge, because the capacity can be changed dynamically every place. Each agent moves in principle based on local information around oneself. However, as for the cases that the inside of stairs has been clogged up, wide area information equivalent to the broadcast in the hall is conveyed to agents after pre-determined time. Comparative study with the real measurement and simulation was carried out about the refuge time of the fire drill that was performed in a university building of 12 stories. © 2013 Springer-Verlag.

We have previously reported that Aloe vera gel had hypoglycemic activity and anti-obesity effects, although the effect on alcoholic fatty liver was unclear. We examined in this present study the effect of an Aloe vera gel extract (AVGE) on hepatic lipid metabolism by using an ethanol-induced transient fatty liver mouse model. Ethanol (3 g/kg of mouse weight) was orally administered to induce an accumulation of triglyceride (TG) and increase the mRNA expression of such lipogenic genes as sterol regulatory element-binding protein-1 (SREBP-1) and fatty acid synthase (FASN) in the liver. Although ethanol ingestion caused a 5.4-fold increase in liver TG, pre-treating with AVGE (1 mg/kg/d) for 1 week significantly suppressed this elevation of the ethanol-induced liver TG level. The expression of lipogenic genes was also lower in the AVGE pre-treatment group than in the control group. This inhibitory effect on the ethanol-induced accumulation of TG was attributed to a reduction in the expression of lipogenic genes that were increased by ethanol.

In this study, the effect of defocus blur on the avoidance of interocular suppression in half-occluded zones, which are the monocular zones formed by occlusion, was examined. Six human adults observed a pair of colored random-dot stereograms, and the cumulative time of disappearance of the half-occluded zones was measured. There were three defocus blur conditions (blurry-background, blurry-occluder, and nonblur) and two fixation conditions (fixation-front and fixation-back). The author found that the cumulative time of disappearance was shorter under the blurrybackground condition of the fixation-front condition and under the blurry-occluder condition of the fixation-back condition than under the other conditions. These results indicate that ecologically valid defocus blur contributes to the avoidance of interocular suppression in the half-occluded zones. © 2014, The Optical Society of Japan.
