  • Hoang, Dai Long; Hong, Tran Thi; Nakashima, Yasuhiko (MDPI, 2020-04-19)
    Physical layer encryption (PLE) is a new research trend for securing data in communication systems. However, conventional procedures in works on PLE are of high complexity and degrade the packet error rate (PER) performance ...
  • shinagawa, seitaro; yoshino, koichiro; SEYED HOSSEIN, ALAVI; KALLIRROI, GEORGILA; DAVID, TRAUM; SAKRIANI, SAKTI; Nakamura, Satoshi (IEEE, 2020-03-25)
    We propose an interactive image editing system that has a confirmation dialogue strategy using an entropy-based uncertainty calculation on its generated images with Deep Convolutional Generative Adversarial Networks (DCGAN). ...
  • Nakasai, Keitaro; Hata, Hideaki; Matsumoto, Kenichi (IEEE, 2018-10-22)
    Eclipse, an open source software project, acknowledges its donors by presenting donation badges. However, the effect of this strategy is unknown. We found that donation badges are appealing for donors and organizers because ...

    レガシーなメインフレームシステムには,拡張子が存在せずプログラミング言語が不明なソースコードファイルが多数存在する.レガシーシステムを分析する際には各ソースコードファイルのプログラミング言語を判定する必要があるが,これを手作業で行うと多大な労力が必要となってしまう.本研究ではプログラミング言語の判定作業を支援するために,手作業で判定すべきファイルの代表をクラスタリングによって選出する手法を提案する.正確な判定を支援するため,提案手法はパ ...
  • Arnaud, Delmotte; Tanaka, Kenichiro; Kubo, Hiroyuki; Funatomi, Takuya; Mukaigawa, Yasuhiro (IEEE, 2019-12-25)
    We propose a new blind watermarking algorithm for three-dimensional (3D) printed objects that has applications in metadata embedding, robotic grasping, counterfeit prevention, and crime investigation. Our method can be ...
  • 上村 , 恭平; 中才, 恵太朗; 大神, 勝也; 畑, 秀明; 一ノ瀬, 智浩; 松本, 健一; 飯田, 元 (日本ソフトウェア科学会, 2019-01-25)
    ソフトウェア工学において,ソフトウェア開発データを分析・可視化し,エビデンスに基づく意思決定を支援するソフトウェアアナリティクスが注目されている.分析や可視化の技術は多数提案されているが,独立して開発されているため,実務者や研究者にとって様々な技術を統一的に活用することは容易でない.そこで我々は,オープンなソフトウェア開発データを有用な形式で公開し,複数の可視化を提供するWebサービス,Codosseumを開発した.具体的には,現在,メ ...
  • Kobayashi, Yasumasa; Fujimoto, Yuichiro; Fujita, Kinya (IEEE, 2019-07-15)
    Notifications of e-mail arrivals at inappropriate times disrupt workers engaged in intellectual activities and reduce their productivity. We propose an e-mail delivery mediation system to deal with this issue. The system ...
  • Kano, Takatomo; Sakti Sakriani, Watiasri; Nakamura, Satoshi (IEEE, 2020-04-20)
    Directly translating spoken utterances from a source language to a target language is challenging because it requires a fundamental transformation in both linguistic and para/non-linguistic features. Traditional speech-to-speech ...
  • Kaplan, Oral; Yamamoto, Goshiro; Taketomi, Takafumi; Plopski, Alexander; Sandor, Christian; Kato, Hirokazu (MDPI, 2018-11-07)
    In this work, we compare the exergaming experience of young and old individuals under four difficulty adjustment methods. Physical inactivity is a leading cause of numerous health conditions including heart diseases, ...
  • Nakamura, Yuta; YuanYu, Zhang; Sasabe, Masahiro; Kasahara, Shoji (MDPI, 2020-03-24)
    Due to the rapid penetration of the Internet of Things (IoT) into human life, illegal access to IoT resources (e.g., data and actuators) has greatly threatened our safety. Access control, which specifies who (i.e., subjects) ...
  • Dawar, Khan; Sehat, Ullah; Syed, Nabi (MDPI, 2019-12-17)
    Indoor navigation and localization has gained a key attention of the researchers in the recent decades. Various technologies such as WiFi, Bluetooth, Ultra Wideband (UWB), and Radio-frequency identification (RFID) have ...
  • Polvi, Jarkko; Taketomi, Takafumi; Moteki, Atsunori; Yoshitake, Toshiyuki; Fukuoka, Toshiyuki; Yamamoto, Goshiro; Sandor, Christian; Kato, Hirokazu (IEEE, 2018-07-01)
    Inspection tasks focus on observation of the environment and are required in many industrial domains. Inspectors usually execute these tasks by using a guide such as a paper manual, and directly observing the environment. ...
  • Ogami, Katsuya; Nakasai, Keitaro; Hata, Hideaki; Matsumoto, Kenichi (日本ソフトウェア科学会, 2019-04-26)
    アプリケーションのパフォーマンス改善において,実行時間を解析するプロファイラは有用と思われる.しかし,既存のプロファイラは特定の実行シナリオのもとプロファイリング時間を事前に設定する必要があり,実行シナリオなしでシステムのボトルネックを見つけることは難しい.また,各メソッドごとの実行時間を表示するインタフェースはソフトウェアの階層構造上における実行モジュールの位置などを把握することが難しい.これらの課題に対処するため,リアルタイムでパフ ...
  • UEDA, Yuki; IHARA, Akinori; ISHIO, Takash; HIRAO, Toshiki; MATSUMOTO, ,Kenichi (The Institute of Electronics, Information and Communication Engineers, 2018-11-01)
    Peer code review is key to ensuring the absence of software defects. To reduce review costs, software developers adopt code convention checking tools that automatically identify maintainability issues in source code. ...
  • Tokuda, Tomoki; Yoshimoto, Junichiro; Shimizu, Yu; Okada, Go; Takamura, Masahiro; Okamoto, Yasumasa; Yamawaki, Shigeto; Doya, Kenji (Springer Nature, 2018-09-20)
    It is well known that depressive disorder is heterogeneous, yet little is known about its neurophysiological subtypes. In the present study, we identified neurophysiological subtypes of depression related to specific neural ...
  • Khan, Dawar; Rehman, Inam ur; Ullah, Sehat; Ahmad, Waheed; Cheng, Zhanglin; Jabeen, Gul; Kato, Hirokazu (MDPI AG, 2019-10-16)

  • Andros, Tjandra; Sakriani, Sakti; Satoshi, Nakamura (IEEE, 2020-03-02)
    Despite the close relationship between speech perception and production, research in automatic speech recognition (ASR) and text-to-speech synthesis (TTS) has progressed more or less independently without exerting much ...
  • Funatomi, Takuya; Kubo, Hiroyuki; Mukaigawa, Yasuhiro (Elsevier, 2019-12)
