  • Kula, Raula Gaikovina; Roover, Coen De; German, Daniel M.; Ishio, Takashi; Inoue, Katsuro (IEEE, 2018)
    The popularity of super repositories such as Maven Central and the CRAN is a testament to software reuse activities in both open-source and commercial projects alike. However, several studies have highlighted the risks and ...
  • Oku, Kenta; Nakajima, Shinsuke; Miyazaki, Jun; Uemura, Shunsuke; Kato, Hirokazu; Hattori, Fumio (CARS-2010, 2010)
    This paper proposes a recommendation system considering users' past / current / future contexts. We define users' contexts as “users' situations and conditions that influence their preference in their information choice. ...
  • Yamamoto, Goshiro; Asghar, Zeeshan; Uranishi, Yuki; Taketomi, Takafumi; Sandor, Christian; Kuroda, Tomohiro; Pulli, Petri; Kato, Hirokazu (ICDVRAT and the University of Reading., 2014)
    We propose a grid-pattern indicating interface to provide instructions remotely from remote site to support independent daily life of senior citizens. Our aim is to realize smooth and easy telecommunication between supported ...
  • Ikeda, Sei; Tanaka, Hiroki; Manabe, Yoshitsugu; Kato, Hirokazu (VTT, 2011)
    This paper reports an evaluation experiment using our prototype system which dynamically projects ruled lines on a sheet of paper to support a user in layout design. The system projects lines at proper positions depending ...
  • Keyaki, Atsushi; Miyazaki, Jun; Hatano, Kenji; Yamamoto, Goshiro; Taketomi, Takafumi; Kato, Hirokazu (National Institute of Informatics, 2013)
    In this paper, we try to apply an approach of XML element retrieval to 1CLICK-2. The aim of XML element retrieval is to identify key points in structured documents, and propose them to system users. We believe that the aim ...
  • Plopski, Alexander; Nitschke, Christian; Kiyokawa, Kiyoshi; Schmalstieg, Dieter; Takemura, Haruo (Eurographics Association, 2015)
    Passive eye-pose estimation methods that recover the eye-pose from natural images generally suffer from low accuracy, the result of a static eye model, and the recovery of the eye model from the estimated iris contour. ...
  • Duong, Quang-Thang; Okada, Minoru (The Institute of Electronics, Information and Communication Engineers, 2018-10-01)
    This paper investigates receive power control for multiuser inductive power transfer (IPT) systems with a single-frequency coil array. The primary task is to optimize the transmit coil currents to minimize the total input ...
  • Todorov, Boris; Kula, Raula Gaikovina; Ishio, Takashi; Inoue, Katsuro (IEEE, 2017)
    In software development, software reuse has become a pivotal factor in creating and providing high-quality software at a reduced cost. The reuse of a code creates dependencies, which as they increase over time become ...
  • Nakamura, Masahide; Monden, Akito; Itoh, Tomoaki; Matsumoto, Ken-ichi; Kanzaki, Yuichiro; Satoh, Hirotsugu (IEEE, 2003)
    We present a method to estimate the cost of mental (hand) simulation of programs. In mental simulation, human short term memory is extensively used to recall and memorize values of variables. When the simulation reaches a ...
  • Kanzaki, Yuichiro; Monden, Akito; Nakamura, Masahide; Matsumoto, Ken-ichi (IEEE, 2003)
    In this paper, we present a new method to protect software against illegal acts of hacking. The key idea is to add a mechanism of self-modifying codes to the original program, so that the original program becomes hard to ...
  • Igaki, Hiroshi; Nakamura, Masahide; Matsumoto, Ken-ichi (IEEE, 2005)
    In the next-generation home network systems (HNS), interoperability among multi-vendor appliances is a challenging issue to implement value-added integrated services. This paper presents a service-oriented framework to ...
  • Monden, Akito; Iida, Hajimu; Matsumoto, Kenichi; Inoue, Katsuro; Torii, Koji (IEEE, 2000)
    Java programs distributed through the Internet are now suffering from program theft. This is because Java programs can be easily decomposed into reusable class files and even decompiled into source code by program users. ...
  • Morisaki, Shuji; Monden, Akito; Matsumura, Tomoko; Tamada, Haruaki; Matsumoto, Ken-ichi (IEEE, 2007)
    This paper describes an empirical study to reveal rules associated with defect correction effort. We defined defect correction effort as a quantitative (ratio scale) variable, and extended conventional (nominal scale based) ...
  • Kamei, Yasutaka; Monden, Akito; Matsumoto, Shinsuke; Kakimoto, Takeshi; Matsumoto, Ken-ichi (IEEE, 2007)
    The goal of this paper is to improve the prediction performance of fault-prone module prediction models (fault-proneness models) by employing over/under sampling methods, which are preprocessing procedures for a fit dataset. ...
  • Shihab, Emad; Ihara, Akinori; Kamei, Yasutaka; Ibrahim, Walid M.; Ohira, Masao; Adams, Bram; Hassan, Ahmed E.; Matsumoto, Ken-ichi (IEEE, 2010)
    Bug fixing accounts for a large amount of the software maintenance resources. Generally, bugs are reported, fixed, verified and closed. However, in some cases bugs have to be re-opened. Re-opened bugs increase maintenance ...
  • Matsumoto, Shinsuke; Kamei, Yasutaka; Monden, Akito; Matsumoto, Ken-ichi (IEEE, 2007)
    In this paper, we experimentally evaluated the effect of outlier detection methods to improve the prediction performance of fault-proneness models. Detected outliers were removed from a fit dataset before building a model. ...
  • Tsunoda, Masateru; Matsumura, Tomoko; Matsumoto, Ken-ichi (IEEE, 2010)
    Recently, software size becomes larger, and consequently, not only a software developer but also a software purchaser suffers considerable losses by software project failure. So avoiding project failure is also important ...
  • Uwano, Hidetake; Monden, Akito; Matsumoto, Ken-ichi (IEEE, 2008)
    To build high-reliability software in software development, software review is essential. Typically, software review requires documents from multiple phases such as requirements specification, design document and source ...
  • Nakamura, Masahide; Tanaka, Akihiro; Igaki, Hiroshi; Tamada, Haruaki; Matsumoto, Ken-ichi (IEEE, 2006)
    This paper presents a framework that adapts the conventional home electric appliances with the infrared remote controls (legacy appliances) to the emerging home network system (HNS). The proposed method extensively uses ...
  • Igaki, Hiroshi; Nakamura, Masahide; Matsumoto, Ken-ichi; Aoyama, Mikio (IEEE, 2006)
    The technology of a home network system (HNS) allows integration of several kinds of home appliances to provide a user with value-added integrated services. Development of the integrated HNS services requires implementation ...
