We examine the dependence of information stability on certain medium parameters, namely mean Curie temperature, grain height, and anisotropy constant ratio in 4 Tbpsi heat-assisted magnetic recording, for 10 years archiving. introduce a minimum normalized readout field H0 after archiving an degradation rate R0 during To interpret results, we investigate whether there is correlation between or e...

MusicAustralia is a national music discovery service, developed by the National Library of Australia and ScreenSound Australia, National Film and Sound Archive. The service aims to provide seamless access to music and music information resources, in multiple formats, from custodians across all cultural sectors. This paper describes the development of the service, including its architecture, and...

To explore the potential fruitfulness of the mathematical theory of communication for information science, we examine the question of how to encode a message at the time it is encountered so that it will come to mind at the time it is needed or can be used. After describing some examples of this problem, we propose a prototype computer program and an experiment, and use these to analyze ways of...

THE notes which follow are intended to form a convenient source of reference for clinicians and o.hers who encounter individuals and families with interesting variations and traits. As specific abnormal traits are usually uncommon and are seldom encountered, the individual clinician may have to spend much time searching for guidance on what information he should collect which may be relevant to...

フジテレビでは日本全国の情報カメラ映像を収録し，地震発生時には即座に地震映像の送出を実現する災害情報カメラ収録システム「TOREZO」を開発した．従来の情報カメラ映像システムはフジテレビへ素材を集約することから中央集約型であり，映像が1ヵ所に集中するため災害耐性が低かったが，ハイブリッドクラウドでの実装により，災害に強いシステムを構築することができた．系列局すべての情報カメラ映像をクラウドにより共有することで，局間の素材伝送などの人的・設備的負担を軽減すると同時に，系列局全体の災害放送能力の増強に成功した．地震映像の切り出しにおいては，従来の地震速報データに加えてリアルタイム震度情報を活用することで，高速かつ高精度での切り出しを実現することができた．本システムにより，日本全国の情報カメラ映像の収録から，地震映像の切り出し，送出システムへのファイル転送までが自動化され，速報性が向上した．
