    This paper proposes a method to extract and visualize a library update history in a project. The method identifies reused library versions by comparing source code in a product with existing versions of the library so that ...
  • Tsuchida, Masashi; Ooshita, Fukuhito; Inoue, Michiko (The Institute of Electronics, Information and Communication Engineers, 2018-03-01)
    We propose an algorithm for the gathering problem of mobile agents in arbitrary networks (graphs) with Byzantine agents. Our algorithm can make all correct agents meet at a single node in O(fm) time (f is the upper bound ...
  • Ojetunde, Babatunde; Shibata, Naoki; Gao, Juntao (Information Processing Society of Japan, 2018-02-15)
    Secure communications is essential in many areas such as disaster management and battlefield communications. To detect and prevent attacks in such applications, most existing protocols adopt a cryptography-based approach, ...
  • Krichenbauer, Max; Yamamoto, Goshiro; Taketomi, Takafumi; Sandor, Christian; Kato, Hirokazu (IEEE, 2018-02-01)
    Virtual Reality (VR) Head-Mounted Displays (HMDs) are on the verge of becoming commodity hardware available to the average user and feasible to use as a tool for 3D work. Some HMDs include front-facing cameras, enabling ...
  • Paderna, Ryan; Hou, Yafei; Thang, Duong Quang; Higashino, Takeshi; Okada, Minoru (一般社団法人 映像情報メディア学会, 2018-01-01)
    In order to realize next generation digital terrestrial television broadcasting (DTTB) systems, the currently deployed Integrated Services Digital Broadcasting Terrestrial (ISDB-T) is still essential due to the spectrum-scarcity. ...
  • Nakamura, Ko; Hayashi, Yu-ichi; Mizuki, Takaaki; Sone, Hideki (IEEE, 2017-11-28)
    In this paper, we present a new information leakage threat combining intentional electromagnetic interference (IEMI) and observations of EM leakage. In previous studies, the analysis of secret key information in cryptographic ...
  • Soriano, Jaymar; Kubo, Takatomi; Inoue, Takao; Kida, Hiroyuki; Yamakawa, Toshitaka; Suzuki, Michiyasu; Ikeda, Kazushi (Public Library of Science, 2017-10-05)
    Experiments with drug-induced epilepsy in rat brains and epileptic human brain region reveal that focal cooling can suppress epileptic discharges without affecting the brain’s normal neurological function. Findings suggest ...
  • Kawai, Norihiko; Sato, Tomokazu; Nakashima, Yuta; Yokoya, Naokazu (IEEE, 2017-10-01)
    Augmented reality (AR) marker hiding is a technique to visually remove AR markers in a real-time video stream. A conventional approach transforms a background image with a homography matrix calculated on the basis of a ...
  • Damien Constantine, Rompapas; Aitor, Rovira; Alexander, Plopski; Christian, Sandor; 武富, 貴史; 山本, 豪志朗; 加藤, 博一; Ikeda, Sei (2017-09-18)
    Augmented Reality (AR) superimposes computer graphics (CG) onto a user’s view of the real world. A key quality problem in this field is to achieve coherence between reality and CG when the user’s eyes refocus or change ...
  • Zeeshan, Asghar; Niina, Keranen; 山本, 豪志朗; 武富, 貴史; Christian, Sandor; 加藤, 博一; Petri, Pulli (EAI Endorsed Transactions, 2017-09-07)
    We present a design and preliminary evaluation of novel visual guidance of a remote assistive system for the elderly to find hidden objects in a kitchen. Our system has two essential functions; 1) to update a list and ...
