Tar archive format does not support file deduplication scheme, therefore it has drawbacks for utilizing disk storage system efficiently. In this paper, we propose an extended TAR file format called DTAR (Deduplication Tape Archive) which provides file-level deduplication. Key idea of our work is to provide block aligned compressed file that can speed up file insertion and deletion for archiving. Furthermore,...
Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 (PIMNT) thick films with nano-sized grains and a dense film structure were deposited by an aerosol-deposition (AD) method. Unlike bulk PIMNT crystals, the AD films showed a relatively narrow polarization–electric field hysteresis loop due to the nano-grain size effect. The post-annealed AD films had a large energy density resulting from the increasing dielectric...
We present an optimal cutter location (CL) data computation for face-milling of large marine propellers composed of CL point optimization and CL path optimization on a given tool path. The CL point optimization at a single cutter contact (CC) point is conducted by maximizing the effective radius of the face milling cutter, while the CL path optimization on a series of CC points is performed by conforming...
