mzRepeat --- visualization of repeating structures in mass spectrometry


It is hard to analyze the data obtained by analytical instruments due to very large and complex data. I developed visual analytical system, "mzRepeat", for analyzing chemical compounds that have repeating structures, such as lipids and polymers, obtained by mass spectrometer. A feature of mzRepeat is that it shows observed ions in groups that differ only in number of repeating structures. It is especially effective for the analysis of many peaks from samples that contain several molecular species.

大量かつ複雑なデータである分析機器のデータの解析を容易にするため、視覚化を適用する研究をしています。 脂質やポリマーのような繰り返し構造を持つ物質を測定した質量分析のデータの視覚的解析システム「mzRepeat」を作成しました。 mzRepeat は、繰り返し構造の数のみが異なる分子種をまとめて表示する特長を持ち、複数の分子種が混在する試料を測定したマススペクトルの解析において特に有効です.

IchiLAN --- large area internal network monitorig system


The attacks from internal network to external network is a serious issue in enterprises. In the internal network monitoring, we can obtain geographical information such as location of routers and PCs. I developed security monitoring system, "IchiLAN", for Computer Center at the university. "IchiLAN" visualize three different important information to monitor local area network such as logical, temporal and geographical information.

企業等では内部ネットワークから外部ネットワークへの攻撃が問題となっています。 内部ネットワーク監視ではルーターや PC の位置がわかります。 そこで大規模内部ネットワークの一例として電気通信大学情報基盤センターを対象に監視システム「いちらん (IchiLAN)」を作成しました。 IchiLAN は内部ネットワーク監視に重要な論理情報・時間情報・地図情報を視覚化します。
