Thermal Infrared Imaging Experiments of C-Type Asteroid 162173 Ryugu on Hayabusa2

The thermal infrared imager TIR onboard Hayabusa2 has been developed to investigate thermo-physical properties of C-type, near-Earth asteroid 162173 Ryugu. TIR is one of the remote science instruments on Hayabusa2 designed to understand the nature of a volatile-rich solar system small body, but it also has significant mission objectives to provide information on surface physical properties and conditions for sampling site selection as well as the assessment of safe landing operations. TIR is based on a two-dimensional uncooled micro-bolometer array inherited from the Longwave Infrared Camera LIR on Akatsuki (Fukuhara et al., 2011). TIR takes images of thermal infrared emission in 8 to 12 μm with a field of view of 16×12∘ and a spatial resolution of 0.05∘ per pixel. TIR covers the temperature range from 150 to 460 K, including the well calibrated range from 230 to 420 K. Temperature accuracy is within 2 K or better for summed images, and the relative accuracy or noise equivalent temperature difference (NETD) at each of pixels is 0.4 K or lower for the well-calibrated temperature range. TIR takes a couple of images with shutter open and closed, the corresponding dark frame, and provides a true thermal image by dark frame subtraction. Data processing involves summation of multiple images, image processing including the StarPixel compression (Hihara et al., 2014), and transfer to the data recorder in the spacecraft digital electronics (DE). We report the scientific and mission objectives of TIR, the requirements and constraints for the instrument specifications, the designed instrumentation and the pre-flight and in-flight performances of TIR, as well as its observation plan during the Hayabusa2 mission

Welsh Nationalism and Cultural Identity

本論考は政治学と比較文化論の立場からウェールズのナショナリズムについて考察したものである。ナショナリズムを一般的に定義するのではなく、むしろナショナリズムがどのように形成されるのか、そのメカニズムを、ウェールズをケース・スタディーの対象に選んで分析したが、とりわけ冷戦後のヨーロッパの政治的状況の激変、今日のグローバリズムの先駆けであるイギリス帝国主義政策ノイデオロギー的支柱となった「英国化」の本質、さらに言語と文化的アイデンティティーの関係の3つをウェールズという文化的磁場に集約させる形で議論を展開させている。This article aims at elucidating the nature of Welsh nationalism in terms of politics and cultural discourse. Rather than defining nationalism in abstract terms, the article concentrates on clarifying the mechanism of how it is formed, taking Wales as an example. It also takes into consideration: 1) the dramatic changes of European political situation in the post-cold-war era, 2) the concept of Anglicization as the ideological support to the management of the British Empire which can be regarded as the model of today's globalization, and 3) the relationship between language and cultural identity.研究論文application/pdfdepartmental bulletin pape
