    災害地の建物で救助活動を行う際,アドホックネットワークは有効な通信手段であると見込まれている.本稿では,無線ネットワークノードを風船に取り付けて建物周囲の空間に設置し,建物内部をカバーする無線ネットワークの構築手法を提案する.その際,設置コストを下げ,かつ,短時間でネットワークを構築するためには,用いるノード数をできるだけ少なくすることは重要である.しかし,対象問題はNP困難な三次元配置問題であり,最適解を求めることは実際上困難である. ...

    A bisanthra-thianthrene has been synthesized and the oxidation property was studied to show that the bis(tetracene radical cation) linked by a dithiin ring is more stable than the π-expanded dithianonacene dication.
  • Hiroshi Saruwatari; Hiroaki Yamajo; Tomoya Takatani; Tsuyoki Nishikawa; Kiyohiro Shikano (電子情報通信学会, 2005-09)
    We propose a new two-stage blind separation and deconvolution strategy for multiple-input multiple-output (MIMO)-FIR systems driven by colored sound sources, in which single-input multiple-output (SIMO)-model-based ICA ...

    A new two-stage blind source separation (BSS) method for convolutive mixtures of speech is proposed, in which a single-input multiple-output (SIMO)-model-based independent component analysis (ICA) and a new SIMO-model-based ...
  • Prasad, Rajkishore; Saruwatari, Hiroshi; Shikano, Kiyohiro (電子情報通信学会, 2005-07)
    This paper presents a study on the blind separation of a convoluted mixture of speech signals using Frequency Domain Independent Component Analysis (FDICA) algorithm based on the negentropy maximization of Time Frequency ...
  • Hiroshi Saruwatari; Satoshi Kurita; Kazuya Takeda; Fumitada Itakura; Tsuyoki Nishikawa; Kiyohiro Shikano (Hindawi Publishing Corporation, 2003-11)
    We describe a new method of blind source separation (BSS) on a microphone array combining subband independent component analysis (ICA) and beamforming. The proposed array system consists of the following three sections: ...
  • Tsuyoki Nishikawa; Hiroshi Saruwatari; Kiyohiro Shikano (電子情報通信学会, 2003-04)
    We propose a new algorithm for blind source separation (BSS), in which frequency-domain independent component analysis (FDICA) and time-domain ICA (TDICA) are combined to achieve a superior source-separation performance ...
  • 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 ...
  • Jun Kohyama; Tsukasa Sanosaka; Akinori Tokunaga; Eriko Takatsuka; Keita Tsujimura; Hideyuki Okano; Kinichi Nakashima (Rockefeller University Press, 2010-04)
    Once they have differentiated, cells retain their individual character and repress genes that are specifically expressed in other cell lineages, but how alternative fate choice is restricted during and/or after differentiation ...
  • Goshu Nagino; Makoto Shozakai; Tomoki Toda; Hiroshi Saruwatari; Kiyohiro Shikano (電子情報通信学会, 2008-03)
    This paper proposes a technique for building an effective speech corpus with lower cost by utilizing a statistical multidimensional scaling method. The statistical multidimensional scaling method visualizes multiple HMM ...
  • Kume, Hideyuki; Sato, Tomokazu; Yokoya, Naokazu (Elsevier, 2015-05-19)
    In this paper, a new pipeline of structure-from-motion for ground-view images is proposed that uses feature points on an aerial image as references for removing accumulative errors. The challenge here is to design a method ...

    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 ...
  • Zhang, Shu; Iida, Katsuyoshi; Yamaguchi, Suguru (Institute of Electronics, Information and Communication Engineers, 2003-12-01)
    Because most link-state routing protocols, such as OSPF arid IS-IS, calculate routes using the Dijkstra algorithm which poses scalability problems implementors often introduce an artificial delay to reduce the number of ...
