    Lack of practical development platforms and specific methods of application programming delays extensive real-life deployment of smart spaces. Virtual shared workspace is a reasonable scenario for evaluation of the smart spaces paradigm maturity. In this paper we consider SmartRoom system, which is Smart-M3 based open source implementation of virtual shared workspaces. Such collaboration activity as conference or meeting is performed in a room equipped with computing and presentational devices as well as accessing Internet services. Personal mobile devices are primary tools for users. Although the Smart-M3 platform is still a research prototype we show that its existing capability is sufficient for developing certain services for practical use. Functionality of SmartRoom services is not finely tuned and not strictly limited by activity domain. Advanced service construction with context awareness, personalization, and augmentation is possible. We illustrate these properties by introducing e-Tourism services for use in SmartRoom collaborative activity

    Get PDF
    The paper presents an intelligent mobile tourist guide architecture that allows tourists to get information about attractions around the current geographic location based on tourist context and estimations of other tourists. Information about attractions (images and description blocks) is extracted from different internet services (like Wikipedia, Wikivoyage, Wikitravel, Panoramio, Flickr) “on the fly” that allows to use mobile tourist guide in any region of the world and get actual at the moment information. The mobile tourist guide provides information about public transport and car sharing possibilities for the tourist with drivers nearby for comfortable reaching preferred attractions. It is based on the smart space technology that provides possibilities of personal devices and different services seamless integration. The paper also discusses services interaction in smart space that allows to implement majority of mobile tourist guide tasks in computational power devices and use personal mobile devices only for results visualization

    Get PDF
    A smart space enhances a networked computing environment by enabling information sharing for a multitude of local digital devices and global resources from the Internet. We consider the M3 architecture (multi-device, multi-vendor, multi-domain) for creating smart spaces, which integrates technologies from two innovative concepts: the Semantic Web and the Internet of Things. Our research focus is on analyses of the capabilities of Smart-M3 platform, which provides software implementations for such a central element of an M3 smart space as Semantic Information Broker (SIB). The paper presents a state-of-the-art and contributes our systematized vision on the SIB design and implementation. The analyzed open source SIB implementations include the original Smart-M3 piglet-based SIB, its optimized descendant RedSIB, OSGi SIB for Java devices, pySIB for Python devices, and CuteSIB for Qt devices. We also analyze the design of proprietary or incomplete SIB implementations: RIBS for embedded devices and ADK SIB built upon the OSGi framework with integration in the Eclipse Integrated Development Environment. The theoretical study is augmented with experimental evaluation of available SIB implementations

    Get PDF
    The paper proposes a description of information decision support system in the tourism domain and a set of methods and algorithms for generating recommendations for a user that allow significant increase of the system usability. The system generates for the user recommendations which attractions at the moment are better to attend based on the user preferences and the current situation in the location area. The system also allows showing the user information about interesting attraction in more detail, which is based on analyzing information evaluations made by other users

    Active control by a mobile client of subscription notifications in smart space

    Get PDF
    Smart space supports interaction of multiple participants though information sharing. This kind of interaction is indirect and networked. For detection of changes, which come in parallel from other participants, a participant applies the subscription operation. It allows receiving notifications passively on a regular basis. Absolutely dependable delivery of notifications cannot be guaranteed in modern computing environments. In particular, wireless networks are subject of frequent faults, making the subscription operation less reliable for mobile clients in smart spaces. In this paper, we study the problem of active control by a client in receiving subscription notifications. We introduce a simple mathematical model for control the check interval for subscription notifications, which ensures client adaptation to the notification loss rate

    Towards Mobility-as-a-Service: a cross-case analysis of public authorities' roles in the development of ICT-supported integrated mobility schemes

    Get PDF
    Automobiles have become counter-productive. Negative externalities resulting from car use have overcome the social benefits automobiles brought when initially introduced. Having shaped most contemporary transportation systems, the automobility regime is known to be hard to revert from. However, as all path-dependent systems, automobility can be subject to tipping points. Among other elements, the Information and Communication Technologies (ICTs) have enabled the development of new solutions having the potential to support a paradigm shift. At the forefront of ICT-enabled developments, so-called ICT-supported integrated mobility schemes have emerged, encompassing smart transportation cards, Integrated Mobility Platforms and Mobility-as-a-Service, that bundle different transport offers together and aim at providing users with a mobility solution of a level of service competitive with the one provided by private cars, ultimately holding the promise of supporting a shift from vehicle ownership to mobility usership and potentially help unlatching transportation systems from the current automobility lock-in. However, most of those solutions are being proposed by the private sector, which often has different interests than the public sector. While the organization of transport usually falls under the responsibility of public actors, new governance structures are needed in order to make the most out of ICT-supported integrated mobility schemes. Hence, this thesis aims at shedding light on the role that public bodies are playing into the birth of smart cards, integrated mobility platforms and MaaS, and more specifically on the way they are governing their development. A case study strategy was employed in this thesis, where, building on grey literature and semi-structured interviews, the cases of smart cards development in London, integrated mobility platform unfolding in Vienna and Mobility-as-a-Service expansion in Helsinki served as empirical material. Based on a cross-case analysis conducted using governance and socio-technical transition literature, the main findings of this thesis are that (i) public transport authorities and state-owned railway undertakings are usually quite reluctant to ICT-supported integrated mobility schemes brought by external actors and prefer developing those by themselves and stay in control or avoid collaborating; (ii) central governments can act as true enablers by developing visions including strong quantitative targets, showing political support for those solutions, acting as matchmakers between public and private bodies, developing legislation, providing funding and steering, and using network governance to make incumbent regime actors change behaviors; (iii) city governments have a greater role to play by setting stronger quantitative-based visions and stop governing by laissez-faire; (iv) ICT-supported integrated mobility schemes should not be understood as magic bullets and must be combined with demand management policies to be truly effective. By providing thick-descriptions of the nuts and bolts of smart cards, IMP and MaaS development, this thesis contributes to the literature on transport integration, transport governance and socio-technical transitions, and contributes to practice by suggesting fourteen recommendations for public authorities interested in a sustainable and impactful development of ICT-supported integrated mobility schemes

    Negoitation in Modernity : The BAZNAS (National Zakat Collection Agency) and the Philosophy of Zakat (Alms) Socialization in Indonesia

    Get PDF
    To pay Zakat (alms) is an obligation for a Muslim. However, this religious obligation cannot encourage Muslims in Indonesia to pay Zakat. In fact, in several cities, some Zakat organizations are established to collect the zakat. Some of them is the BAZNAS which is spread in most cities in Indonesia. In fact, this organization is a semi-government because there are some collaborations between the BAZNAS and local government in most regions. This collaboration indicates also that it tries to get benefit from the modern and established government structure. This article aims to know the BAZNAS negoitation with modernity, specifically it wants to deal with the BAZNAS zakat socialization. Using a case study, this article finds that the zakat organization like the BAZNAS Kepulauan Meranti Indonesia deals with a complicated negoitation with modernity through its zakat socialization. In fact, there is a religious understanding among Muslims there that to pay zakat is an obligation but it cannot deal with their religious awareness to pay zakat. This article identifies that disseminating the zakat payment obligation is a never ending project. The BAZNAS improves Muslim understanding about Zakat through socialization. Some socialization activities done are using modern instruments but some are not. Keywords : Zakat, BAZNAS (National Zakat Collection Agency), Socialization

    The 5th international PLATE conference (Product Lifetimes and the Environment) addressed product lifetimes in the context of sustainability. The PLATE conference, which has been running since 2015, has successfully been able to establish a solid network of researchers around its core theme. The topic has come to the forefront of current (political, scientific & societal) debates due to its interconnectedness with a number of recent prominent movements, such as the circular economy, eco-design and collaborative consumption. For the 2023 edition of the conference, we encouraged researchers to propose how to extend, widen or critically re-construct thematic sessions for the PLATE conference, and the paper call was constructed based on these proposals. In this 5th PLATE conference, we had 171 paper presentations and 238 participants from 14 different countries. Beside of paper sessions we organized workshops and REPAIR exhibitions

    Social media is revolutionizing the way firms manage their brands. A broad variety of platforms provide businesses an opportunity to engage in bidirectional dialogue with their customers, the effect of which is to enhance the brand/consumer relationship. This paper contends that virtual brand communities of the type that form through social media have an important role to play in the development of a brand’s personality. Using a case study approach we demonstrate how one firm has adopted Facebook to provide their brand community with a voice which contributes to the development of the brand narrative. We find that by using well-crafted content the firm elicits the support of their community and that this interaction contributes to the development of the brand ethos
