「天気をこうかんするキカイ」
鬼塚 充暉 くん(当時8 歳)
雨のところと晴れのところをこうかん
するキカイ。雨がふらなくてこまって
いるさばくと、雨ばかりで外であそぶ
ことができない子どもたちのいるとこ
ろの天気をこうかんする。どっちもう
れしくなるゆめのキカイ。

Prospect and Recent Research & Development for Civil Use Autonomous Unmanned Aircraft as UAV and MAV

Kenzo NONAMI

Journal of System Design and Dynamics (2007) DOI:10.1299/jsdd.1.120

This paper describes the present state of research and development for civil use autonomous unmanned aircraft. In particular,the history of civil use UAVs, the research and development in the world and in Japan, and the subjects and prospects for control and operation systems of civil use autonomous UAVs are described.

Large eddy simulation with modeled wall-stress: recent progress
and future directions

Johan LARSSON, Soshi KAWAI, Julien BODART, Ivan BERMEJO-MORENO
Mechanical Engineering Reviews (2016) DOI:10.1299/mer.15-00418

The paper provides a brief introduction to the near-wall problem of LES and how it can be solved through modeling of the near-wall turbulence. The distinctions and key differences between different approaches are emphasized, both in terms of fidelity (LES, wall-modeled LES, and DES) and in terms of different wall-modeled LES approaches (hybrid LES/RANS and wall-stress-models). The focus is on approaches that model the wall-stress directly, i.e., methods for which the LES equations are formally solved all the way down to the wall. Progress over the last decade is reviewed, and the most important and promising directions for future research are discussed.

How is residual stress/strain detected in bone tissue ?

Shigeru TADANO, Satoshi YAMADA
Mechanical Engineering Reviews (2016) DOI:10.1299/mer.15-00291

Recent experimental approaches were reviewed to the residual stress/strain in bone tissue using X-ray diffraction (XRD) techniques.After a brief introduction of the experimental methods and obtained results, we discussed the generation mechanisms and biomechanical implications of the residual stress/strain in bone tissue. Strain gauge approaches provided the existence of residual stresses in the bone at the whole bone level. XRD approaches have also provided the existence of residual stresses at the tissue and mineral phase levels. The residual strains at the mineral phase related to the degree of orientation of the HAp crystals. The distributions of residual stress wereobtained around the surface and along the radial depth of the diaphysis of quadrupedal extremities. The correlation between the residual stress and the osteon structures was indicated and the difference of residual stress with growth was revealed. It would appear that the residual stress state might be generated by the indeterminate structure in the hierarchical structures of the bone tissue relating to bone adaptation with the bone formation and reconstruction process. A long-term study is needed to better understand the generation and biomechanical implications of residual stress in bone tissue throughout the hierarchical structure during maturation and aging.
