  • ICIW - Free Information Usage System on the Network Introducing DACS Scheme
    Second International Conference on Internet and Web Applications and Services (ICIW'07), 2007
    Co-Authors: Kazuya Odagiri, Rihito Yaegashi, Masaharu Tadauchi, Naohiro Ishii
    Abstract:

    As a Communication Mean, personal portal, which is an entrance where each user can acquire his/her interested information on the network, is often used. We have problems to realize the personal portal described as follows. First, the program to realize the personal portal, which is located on a specific Web server, becomes large-scaled and complicated. Moreover, because Web pages as personal portal depend on that program, those pages can't always be useful for each user equally. To solve these problem, we develop two kinds of new Web service which are realized on the network introducing DACS Scheme, which is the network management scheme by Communication control of client computers. By use of these Web Services, regardless of information starage form, each user can create the customized personal portal to use information on the network easily and freely for oneself. That is, a free information usage system is realized.

  • SNPD (1) - Information Usage System by Static Portal Page
    Eighth ACIS International Conference on Software Engineering Artificial Intelligence Networking and Parallel Distributed Computing (SNPD 2007), 2007
    Co-Authors: Kazuya Odagiri, Rihito Yaegashi, Masaharu Tadauchi, Naohiro Ishii
    Abstract:

    As a Communication Mean, Personal Portal which is an entrance where each user can acquire his/her interested information on the network, is often used. We have problems on the existing Personal Portal described as follows. First, the program to realize the Personal Portal which is located on a specific Web Server, becomes large-scaled and complicated. Because Web pages as Personal Portal depend on that program, those Web pages can't always be useful for each user equally. Therefore, to solve these problems, we developed two kinds of new Web Service which are realized on the network with DACS(Destination Addressing Control System) Scheme, which is the network management scheme by Communication control of client computers. By use of these Web Services, each user can create the customized Personal Portal, which displays the information by a user unit, for using in actual network easily and freely for oneself. That is, a free information usage system is realized.

DACS Web Service is realized by extending two kinds of functions of Web Service respectively and integrating these functions. As the result, each user can create the customized Web page as Personal Portal, which will be often useful in actual network.

  • New Web Service Based on Extended DACS Scheme
    2006
    Co-Authors: Kazuya Odagiri, Rihito Yaegashi, Masaharu Tadauchi, Naohiro Ishii
    Abstract:

    Summary Web pages are often used as a Communication Mean other than E-mail and telephone in the organization. It will be useful to send the related information to respective users by using Web pages. The related information is gathered by the search and extraction of user’s information in databases. Then, it will be notified to user by the program such as CGI on the server. To realize these processings, a large-scaled mechanism will be needed to gather the distributed data on the network and to create Web pages, dynamically. Therefore, a new Web Services based on the extended DACS Scheme is proposed and examined. The DACS Scheme is developed by authors. In the new Web Service, it is possible to display the information related to user only by inputting an URL on Web Browser. As the result, it is possible to display the information on the window divided by the frames on Web Browser. Then, the information is extracted from each server. If the static Web page can be created in HTML, user can create the useful Web page efficiently and freely. The new application form of the information usage is developed by using the proposed extended DACS Scheme.

  • Spelling with non-invasive Brain-Computer Interfaces - Current and future trends.
    Journal of Physiology - Paris, 2017
    Co-Authors: Hubert Cecotti
    Abstract:

    Brain-Computer Interfaces (BCIs) have become a large research field that include challenges mainly in neuroscience, signal processing, machine learning and user interface. A non-invasive BCI can allow the direct Communication between humans and computers by analyzing electrical brain activity, recorded at the surface of the scalp with electroencephalography. The main purpose for BCIs is to enable Communication for people with severe disabilities. Spelling is one of the first BCI application, it corresponds to the main Communication Mean for people who are unable to speak. While spelling can be the most basic application it remains a benchmark for Communication applications and one challenge in the BCI community for some patients. This paper proposes a review of the current main strategies, and their limitations, for spelling words. It includes recent BCIs based on P300, steady-state visual evoked potentials and motor imagery.

  • A Molecular Optical Channel Model based on Phonon-Assisted Energy Transfer Phenomenon
    IEEE Transactions on Communications, 2018
    Co-Authors: Valeria Loscrí, Bige D. Unluturk, Anna Maria Vegni
    Abstract:

    —Recent progress in the field of nanotechnology is enabling Communication between nanodevices to be considered also for in-vivo applications. In particular, nanodevices enabling light-controlled process have started to attract a lot of interest in the research community, due to potential applications like health-care wearable devices, intra-body applications and optogenetics, whose main objective is to stimulate neurons by the Means of the light signals. Leveraging on these premises, we consider upconversion phenomenon , namely the ability of specific nanoparticles to convert low energy radiations (e.g., near-infrared radiations) into higher energy radiation (e.g., visible light) via a non-linear process. Energy transfer as viable Communication Mean has been already considered based on Förster-Resonance-Energy Transfer. In this paper, we focus on Phonon-Assisted Energy Transfer, and we analyze the requirements and conditions for generating optical signals from a genuine signal processing point of view. More specifically, based on information theory approach, we derive the conditions to minimize the error probability. We show that the dopant concentration (i.e., concentration of elements drugging a pure material in order to change its features) mostly influences the correct generation of the light signal. The performed analysis is based on experimental results taken from [1], [2].

  • An Acoustic Communication Technique of Nanorobot Swarms for Nanomedicine Applications
    IEEE Transactions on NanoBioscience, 2015
    Co-Authors: Valeria Loscrí, Anna Maria Vegni
    Abstract:

    In this contribution, we present a Communication paradigm among nanodevices, based on acoustic vibrations for medical applications. We consider a swarm of nanorobots able to communicate in a distributed and decentralized fashion, propelled in a biological environment (i.e., the human brain). Each nanorobot is intended to i) recognize a cancer cell, ii) destroy it, and then iii) forward information about the presence of cancer formation to other nanorobots, through acoustic signals. The choice of acoustic waves as Communication Mean is related to the application context, where it is not advisable either to use indiscriminate chemical substances or electromagnetic waves. The effectiveness of the proposed approach is assessed in terms of achievement of the objective (i.e., to destroy the majority of tumor cells), and the velocity of detection and destruction of cancer cells, through a comparison with other related techniques.
