  • Siriaraya, Panote; Wang, Yuanyuan; Zhang, Yihong; Wakamiya, Shoko; Jeszens, Péter; Jatowt, Adam; Kawai, Yukiko (IEEE, 2020-07-27)
    Navigation systems often aid users when traveling in unfamiliar locations. Current navigation systems tend to focus on identifying the shortest or fastest routes between two points. However, path cost expressed in terms ...
  • 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 ...
  • Hara, Takanori; Sasabe, Masahiro; Matsuda, Taiki; Kasahara, Shoji (MDPI, 2020-07-16)
    When a large-scale disaster occurs, each evacuee should move to an appropriate refuge in a speedy and safe manner. Most of the existing studies on the refuge assignment consider the speediness of evacuation and refuge ...

    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 ...
  • Renzo Roel, P. Tan; Kawahara, Jun; Ikeda, Kazushi; Agnes D., Garciano; Kyle Stephen, S. See (International Association of Engineers, 2020-05-29)
    Decision-diagram-based solutions for discrete optimization have been persistently studied. Among these is the use of the zero-suppressed binary decision diagram, a compact graph-based representation for a specified family ...
  • Ding, Ming; Nagashima, Mikihisa; Cho, Sung-Gwi; Takamatsu, Jun; Ogasawara, Tsukasa (IEEE, 2020-07-20)
    Many kinds of lower-limb exoskeletons were developed for walking assistance. However, when controlling these exoskeletons, time-delay due to the computation time and the communication delays is still a general problem. In ...
  • Takatani, Tsuyoshi; Fujita, Koki; Tanaka, Kenichiro; Funatomi, Takuya; Mukaigawa, Yasuhiro (Springer Nature, 2018-06-08)
    UV printer, a digital fabrication tool, can print 2D patterns on 3D objects consisting of various materials by using UV inks which immediately dry through being exposed to ultraviolet light. In general use, the translucency ...

  • Ahmed, Foisal; Shintani, Michihiro; Inoue, Michiko (一般社団法人電子情報通信学会, 2020-09-01)
    Analyzing aging-induced delay degradations of ring oscillators (ROs) is an effective way to detect recycled field-programmable gate arrays (FPGAs). However, it requires a large number of RO measurements for all FPGAs before ...
  • Takatani, Tsuyoshi; Mukaigawa, Yasuhiro; Matsushita, Yasuyuki; Yagi, Yasushi (Springer Nature, 2018-10-23)
    An observed image is composed of multiple components based on optical phenomena, such as light reflection and scattering. Decomposing the observed image into individual components is an important process for various computer ...
  • Muraji, Takeshi; Tanaka, Kenichiro; Funatomi, Takuya; Mukaigawa, Yasuhiro (The Optical Society, 2019-06-20)
    This paper presents a time-of-flight (ToF) measurement method for use in foggy weather. The depth measured by a ToF camera is greatly distorted in fog because the light scattered in the fog reaches the camera much faster ...
  • Gogami, Masaki; Matsuda, Yuki; Arakawa, Yutaka; Yasumoto, Keiichi (IEEE, 2021-03-26)
    Some respondents make careless responses due to the “satisficing,” which is an attempt to complete a questionnaire as quickly and easily as possible. To obtain results that reflect a fact, detecting satisficing and excluding ...
  • 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 ...
  • Higa, Yuki; Kim, Young-Soo; Altaf-Ul-Amin, Md.; Huang, Ming; Ono, Naoaki; Kanaya, Shigehiko (BMC, 2020-10-01)
    Results We examined the diversity of secondary metabolite production in three Monascus species (M. pilosus, M. purpureus, and M. ruber) at both the metabolome level by LCMS analysis and at the genome level. Specifically, ...
  • Pham, Hoai Luan; Tran, Thi Hong; Phan, Tri Dung; Le, Vu Trung Duong; Lam, Duc Khai; Nakashima, Yasuhiko (IEEE, 2020-07-28)
    In the Bitcoin network, computing double SHA-256 values consumes most of the network energy. Therefore, reducing the power consumption and increasing the processing rate for the double SHA-256 algorithm is currently an ...
  • Koge, Daiki; Ono, Naoaki; Huang, Ming; Altaf‐Ul‐Amin, Md.; Kanaya, Shigehiko (Wiley-VCH Verlag, 2020-11-08)
    Deep learning approaches are widely used to search molecular structures for a candidate drug/material. The basic approach in drug/material candidate structure discovery is to embed a relationship that holds between a ...
  • Effendi, Johanes; Sakti, Sakriani; Nakamura, Satoshi (IEEE, 2021-04-07)
    Describing orally what we are seeing is a simple task we do in our daily life. However, in the natural language processing field, this simple task needs to be bridged by a textual modality that helps the system to generalize ...
  • 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 ...
