Structure-reversibility of a two dimensional reflecting random walk and its application to queueing network
Masahiro Kobayashi, Masakiyo Miyazawa, Hiroshi Shimizu
We consider a two dimensional reflecting random walk on the nonnegative integer quadrant. It is assumed that this reflecting random walk has skip free transitions. We are concerned…
Driving Disk Winds and Heating up Hot Coronae by MRI Turbulence
Yuki Io, Takeru K. Suzuki
We investigate the formation of hot coronae and vertical outflows in accretion disks by magneto-rotational turbulence. We perform local three-dimensional (3D) MHD simulations with…
Solving -Nearest Neighbor Problem on Multiple Graphics Processors
Kimikazu Kato, Tikara Hosino
The recommendation system is a software system to predict customers' unknown preferences from known preferences. In the recommendation system, customers' preferences are encoded in…
Degeneracy of Angular Voronoi Diagram
Hidetoshi Muta, Kimikazu Kato
Angular Voronoi diagram was introduced by Asano et al. as fundamental research for a mesh generation. In an angular Voronoi diagram, the edges are curves of degree three. From view…
