20GHz-TDR装置を使った比誘電率測定の特徴

Nondestructive measurements of water content in porous media, e.g., bricks, stones, and compacted soil, are required to assess the deterioration of historical buildings/structures. Unlike conventional methods, time domain reflectometry (TDR) can nondestructively and continuously measure water content by monitoring changes in dielectric constant. The popularly-used TDR instrument, e.g., 1502C of Tektronix Inc., has an effective frequency range of 1GHz while a higher-end TDR instrument, e.g., 86100B+54754A of Agilent Technologies, has that of 20GHz. The 20GHz TDR instrument provided clearer waveforms with a 4cm-long probe than did the 1GHz TDR instrument when a TDR probe was placed in conditions with less water content. Further research is needed for an appropriate design of a TDR probe and for improving a waveform analysis algorithm

Study of passive walker with upper limb

能動的に制御する歩行運動と比較して効率のよい受動歩行をヒューマノイド等へ応用するには，上肢を有する二足歩行モデルでの議論が必要である．つまり，上体の姿勢および腕の動作等の上肢の状態が受動歩行に与える影響を解明しなければならない．しかし，現在までの受動歩行研究の多くは脚部のみを対象としたモデルが多く，胴と腕を有する二足歩行モデルの研究例は少ない．そこで，本研究では腕，胴，脚を有した二足歩行モデルを用い，上体姿勢，腕振り動作の諸条件を変化させることでシミュレーション実験を行った．シミュレーション実験の結果に基づいて上肢を持つ受動歩行の安定性について解析し，報告する

Fracture of the penis: a report of four cases

Four cases of fracture of the penis were treated surgically at our department between 1978 and 1982. No functional disorder has been observed in any case after the treatment. One hundred and ninety cases diagnosed as fracture of the penis reported in the Japanese literature were reviewed and their pathogenesis, diagnosis and therapy were discussed

Present State of UAV and Applications for Civil Engineering

UAV (Unmanned Aerial Vehicle) is effective for remote sensing and obtains high-resolution data at low cost rather than satellite images and aerial photos. However, there is a lot of remote sensing with satellite information, while there is a little remote sensing with UAV photogrammetry. Then the authors researched a present state of UAV and applications for civil engineering. The objectives of this study was to construct a 3D model, to make orthogonal photos, and to calculate NDVI, NDWI, chlorophyll-a, and turbidity distributions and water catchment areas from UAV photogrammetry. In this paper, the authors introduced 3 examples for remote sensing with UAV and discussed possibility of the future on UAV
