Lidar-based individual tree species classification using convolutional neural network

Autor: Tsuyoshi Inoue, Akira Ishii, Hisashi Takamatsu, Tomohiro Mizoguchi, Hiroyuki Nakamura

Publikováno v: Videometrics, Range Imaging, and Applications XIV.

Terrestrial lidar is commonly used for detailed documentation in the field of forest inventory investigation. Recent improvements of point cloud processing techniques enabled efficient and precise computation of an individual tree shape parameters, s

Valence Fluctuation and Domain-Wall Dynamics in Pressure-Induced Neutral-to-Ionic Phase Transition of Organic Charge-Transfer Crystal

Autor: Hisashi Takamatsu, Hiroshi Okamoto, Hideo Kishida, Hiroyuki Matsuzaki

Publikováno v: Journal of the Physical Society of Japan. 74:2925-2928

A pressure-induced neutral-to-ionic ( N – I ) transition in tetrathiafulvalene- p -chroranil was studied by infrared vibration spectra. With increasing pressure, two CO stretching bands probing coe...

Electric field effect on charge and lattice dynamics in TTF-QCl4 and TTF-QBrCl3

Autor: K. Fujinuma, Yasuhiro Tokura, Hideo Kishida, Sachio Horiuchi, Hisashi Takamatsu, Hiroshi Okamoto

Publikováno v: Synthetic Metals. :633-635

Electroreflectance (ER) spectra are measured on the mixed-stack charge transfer (CT) complexes, tetrathiafulvalane (TTF)-2-bromo-3,5,6-trichloro-p-benzoquinone (QBrCl3) and TTF-p-chloranil (QCl4), showing the neutral–ionic (N–I) phase transition.

Ferroelectric nature and real-space observations of domain motions in the organic charge-transfer compound tetrathiafulvalene-p-chloranil

Autor: Hisashi Takamatsu, Ken Fujinuma, Hideo Kishida, Hiroshi Okamoto

Publikováno v: Physical Review B. 80

Ferroelectricity in an organic charge-transfer compound, tetrathiafulvalene-$p$-chloranil (TTF-CA), originating from the one-dimensional valence and lattice instabilities, has been investigated by an electroreflectance (ER) method. Microscopic ER spe
