HaptStarter: Designing Haptic Stimulus Start System for Deaf and Hard of Hearing Sprinters
Akihisa Shitara, Miki Namatame, Sayan Sarcar +2
In this study, we design and develop HaptStarter -- a haptic stimulus start system -- to improve the starting performance of the deaf and hard of hearing (DHH) sprinters. A DHH per…
Single Transition Layer in Mass-Conserving Reaction-Diffusion Systems with Bistable Nonlinearity
Masataka Kuwamura, Takashi Teramoto, Hideo Ikeda
Mass-conserving reaction-diffusion systems with bistable nonlinearity are useful models for studying cell polarity formation, which is a key process in cell division and differenti…
Coherent Stellar Motion in Galactic Spiral Arms by Swing Amplification
Shugo Michikoshi, Eiichiro Kokubo
We perform local -body simulations of disk galaxies and investigate the evolution of spiral arms. We calculate the time autocorrelation of the surface density of spiral arms and…
Dynamics of Porous Dust Aggregates and Gravitational Instability of Their Disk
Shugo Michikoshi, Eiichiro Kokubo
We consider the dynamics of porous icy dust aggregates in a turbulent gas disk and investigate the stability of the disk. We evaluate the random velocity of porous dust aggregates…
Scaling Relations in Coronal Mass Ejections and Energetic Proton Events associated with Solar Superflares
Takuya Takahashi, Yoshiyuki Mizuno, Kazunari Shibata
In order to discuss the potential impact of solar 'superflares' on space weather, we investigated statistical relations among energetic proton peak flux with energy higher than $ 1…
