Tracking Infiltration Front Depth Using Time-lapse Multi-offset Gathers Collected with Array Antenna Ground Penetrating Radar Hirotaka Saito1, Seiichiro Kuroda2, Toshiki Iwasaki1, Haruyuki Fujimaki3, Nobuhito Nagai4, Jacopo Sala5 1Graduate School of Agriculture, Tokyo University of Agriculture and Technology, 2National Institute for Rural Engineering, National Agriculture and Food Research Organization, 3Arid Land Research Center, Tottori University, 4GeoFive Co. Ltd, 53D-Radar Here we present a Ground Penetrating Radar (GPR) system based on a ground-coupled, densely populated antenna array for monitoring the dynamic process of subsurface water infiltration. A time-lapse radar image of the infiltration process allowed estimating the depth of the wetting front during the course of the infiltration process.
Simultaneous Evaluation of Cerebral Hemodynamics and Light Scattering Properties of the In Vivo Rat Brain Using Multispectral Diffuse Reflectance Imaging Izumi Nishidate1, Afrina Mustari1, Satoko Kawauchi2, Shunichi Sato2, Manabu Sato3 1Graduate School of Bio-application & Systems Engineering, Tokyo University of Agriculture & Technology, 2Division of Biomedical Information Sciences, National Defense Medical College Research Institute, 3Graduate School of Science and Engineering, Yamagata University The simultaneous evaluation of cerebral hemodynamics and the light scattering properties of in vivo rat brain tissue is demonstrated using a conventional multispectral diffuse reflectance imaging system.
Construction of Models for Nondestructive Prediction of Ingredient Contents in Blueberries by Near-infrared Spectroscopy Based on HPLC Measurements Wenming Bai1, Norio Yoshimura1, Masao Takayanagi1, Jingai Che2, Naomi Horiuchi2, Isao Ogiwara3 1United Graduate School of Agricultural Science, Tokyo University of Agriculture and Technology, 2Faculty of Agriculture, Tokyo University of Agriculture and Technology, 3Institute of Agriculture, Tokyo University of Agriculture and Technology We present here a protocol to construct and validate models for nondestructive prediction of total sugar, total organic acid, and total anthocyanin content in individual blueberries by near-infrared spectroscopy.
