  • InterOSS@IoT - On the Road to Secure and Privacy-Preserving IoT Ecosystems
    Interoperability and Open-Source Solutions for the Internet of Things, 2017
    Co-Authors: Juan Hernández-serrano, Lars Møller Mikkelsen, Oscar Esparza, Wolfgang Schwarzott, Olga León, Jose L. Munoz, Arne Bröring, Jan Zibuschka
    Abstract:

    The Internet of Things (IoT) is on the rise. Today, various IoT platforms are already available, giving access to myriads of things. Initiatives such as BIG IoT are bringing those IoT platforms together in order to form ecosystems. BIG IoT aims to facilitate cross-platform and cross-Domain Application developments and establish centralized marketplaces to allow resource monetization. This combination of multi-platform Applications, heterogeneity of the IoT, as well as enabling marketing and accounting of resources results in crucial challenges for security and privacy. Hence, this article analyses the requirements for security in IoT ecosystems and outlines solutions followed in the BIG IoT project to tackle those challenges. Concrete analysis of an IoT use case covering aspects such as public, private transportation, and smart parking is also presented.Peer ReviewedPostprint (published version

  • InterOSS@IoT - An Architecture for Interoperable IoT Ecosystems
    Interoperability and Open-Source Solutions for the Internet of Things, 2016
    Co-Authors: Stefan Schmid, Sebastian Käbisch, Andreas Rausch, Martin Lorenz, Achille Zappa, Denis Kramer, Arne Bröring, Yong Wang, Luca Gioppo
    Abstract:

    The Internet of Things (IoT) is maturing and more and more IoT platforms that give access to things are emerging. However, the real potential of the IoT lies in growing IoT cross-Domain ecosystems on top of these platforms that will deliver new, unanticipated value added Applications and services. We identified two crucial aspects that are important to grow an IoT ecosystem: (i) interoperability to enable cross-platform and even cross-Domain Application developments on top of IoT platforms as well as (ii) marketplaces to share and monetize IoT resources. Having these two crucial pillars of an IoT ecosystem in mind, we present in this article the BIG IoT architecture as the foundation to establish IoT ecosystems. The architecture fulfills essential requirements that have been assessed among industry and research organizations as part of the BIG IoT project. We demonstrate a first proof-of-concept implementation in the context of an exemplary smart cities scenario.

  • consumer health search on the web study of web page understandability and its integration in ranking algorithms
    Journal of Medical Internet Research, 2019
    Co-Authors: Guido Zuccon, João R. M. Palotti, Allan Hanbury
    Abstract:

    Understandability plays a key role in ensuring that people accessing health information are capable of gaining insights that can assist them with their health concerns and choices. The access to unclear or misleading information has been shown to negatively impact the health decisions of the general public. The aim of this study was to investigate methods to estimate the understandability of health Web pages and use these to improve the retrieval of information for people seeking health advice on the Web. Our investigation considered methods to automatically estimate the understandability of health information in Web pages, and it provided a thorough evaluation of these methods using human assessments as well as an analysis of preprocessing factors affecting understandability estimations and associated pitfalls. Furthermore, lessons learned for estimating Web page understandability were applied to the construction of retrieval methods, with specific attention to retrieving information understandable by the general public. We found that machine learning techniques were more suitable to estimate health Web page understandability than traditional readability formulae, which are often used as guidelines and benchmark by health information providers on the Web (larger difference found for Pearson correlation of .602 using gradient boosting regressor compared with .438 using Simple Measure of Gobbledygook Index with the Conference and Labs of the Evaluation Forum eHealth 2015 collection). The findings reported in this paper are important for specialized search services tailored to support the general public in seeking health advice on the Web, as they document and empirically validate state-of-the-art techniques and settings for this Domain Application.

  • Regularization of fields for self-force problems in curved spacetime: Foundations and a time-Domain Application
    Physical Review D, 2008
    Co-Authors: Ian Vega, Steven Detweiler
    Abstract:

    We propose an approach for the calculation of self-forces, energy fluxes and waveforms arising from moving point charges in curved spacetimes. As opposed to mode-sum schemes that regularize the self-force derived from the singular retarded field, this approach regularizes the retarded field itself. The singular part of the retarded field is first analytically identified and removed, yielding a finite, differentiable remainder from which the self-force is easily calculated. This regular remainder solves a wave equation which enjoys the benefit of having a non-singular source. Solving this wave equation for the remainder completely avoids the calculation of the singular retarded field along with the attendant difficulties associated with numerically modeling a delta function source. From this differentiable remainder one may compute the self-force, the energy flux, and also a waveform which reflects the effects of the self-force. As a test of principle, we implement this method using a 4th-order (1+1) code, and calculate the self-force for the simple case of a scalar charge moving in a circular orbit around a Schwarzschild black hole. We achieve agreement with frequency-Domain results to ~ 0.1% or better.Comment: 15 pages, 12 figures, 1 table. More figures, extended summar
