Natural band alignment of alloys
Yuichi Ota, Kentaro Kaneko, Takeyoshi Onuma +1
We have calculated formation enthalpies, band gaps, and natural band alignment for alloys by first principles calculation based on density functional theory. T…
Bitstream-Based JPEG Image Encryption with File-Size Preserving
Hiroyuki Kobayashi, Hitoshi Kiya
An encryption scheme of JPEG images in the bitstream domain is proposed. The proposed scheme preserves the JPEG format even after encrypting the images, and the file size of encryp…
A constant-ratio approximation algorithm for a class of hub-and-spoke network design problems and metric labeling problems: star metric case
Yuko Kuroki, Tomomi Matsui
Transportation networks frequently employ hub-and-spoke network architectures to route flows between many origin and destination pairs. Hub facilities work as switching points for…
Development of a Diehard GEM using PTFE insulator substrate
M. Wakabayashi, K. Komiya, T. Tamagawa +4
We have developed the gas electron multiplier (GEM) using polytetrafluoroethylene (PTFE) insulator substrate (PTFE-GEM). Carbonization on insulator layer by discharges shorts the G…
