    Nowadays almost everyone has a mobile phone and even the most basic smartphones often come embedded with a variety of sensors. These sensors, in combination with a large user base, offer huge potential in the realization of crowdsourcing applications. The crowdsourcing aspect is of interest especially in situations where users’ everyday actions can generate data usable in more complex scenarios. The research goal in this paper is to introduce a combination of models for data gathering and analysis of the gathered data, enabling effective data processing of large data sets. Both models are applied and tested in the developed prototype system. In addition, the paper presents the test setup and results of the study, including a description of the web user interface used to illustrate road condition data. The data were collected by a group of users driving on roads in western Finland. Finally, it provides a discussion on the challenges faced in the implementation of the prototype system and a look at the problems related to the analysis of the collected data. In general, the collected data were discovered to be more useful in the assessment of the overall condition of roads, and less useful for finding specific problematic spots on roads, such as potholes.acceptedVersionPeer reviewe

    A multi-agent system (MAS) is a system composed of multiple interacting intelligent agents. Multi-agent systems can be used to solve problems which are difficult or impossible for an individual agent or monolithic system to solve. Agent systems are open and extensible systems that allow for the deployment of autonomous and proactive software components. Multi-agent systems have been brought up and used in several application domains

    European governance challenges in bio-engineering : making perfect life : bio-engineering (in) the 21st century : final report

    Get PDF
    In the STOA project Making Perfect Life four fields were studied of 21st century bio-engineering: engineering of living artefacts, engineering of the body, engineering of the brain, and engineering of intelligent artefacts. This report describes the main results of the project. It shows how developments in the four fields of bio-engineering are shaped by two megatrends: "biology becoming technology" and "technology becoming biology". These developments result in a broadening of the bio-engineering debate in our society. The report addresses the long term views that are inspiring this debate and discusses a multitude of ethical, legal and social issues that arise from bio-engineering developments in the fields described. Against this background four specific developments are studied in more detail: the rise of human genome sequencing, the market introduction of neurodevices, the capturing by information technology of the psychological and physiological states of users, and the pursuit of standardisation in synthetic biology. These developments are taken in this report as a starting point for an analysis of some of the main European governance challenges in 21st century bio-engineering

    Magneto-inductive wireless underground sensor networks: novel longevity model, communication concepts and workarounds to key theoretical issues using analogical thinking

    Get PDF
    This research has attempted to devise novel workarounds to key theoretical issues in magneto-inductive wireless underground sensor networks (WUSNs), founded on analogical thinking (Gassmann & Zeschky 2008). The problem statement for this research can be summarized as follows. There has been a substantial output of research publications in the past 5 years, devoted to theoretically analysing and resolving the issues pertaining to deployment of MI based WUSNs. However, no alternate solution approaches to such theoretical analyses have been considered. The goal of this research was to explore such alternate solution approaches. This research has used the principle of analogical thinking in devising such alternate solution approaches. This research has made several key contributions to the existing body of work. First, this research is the first of its kind to demonstrate by means of review of state-of-the-art research on MI based WUSNs, the largely theoretical genus of the research to the exclusion of alternate solution approaches to circumvent key theoretical issues. Second, this research is the first of its kind to introduce the notion of analogical thinking as a solution approach in finding viable workarounds to theoretical impediments in MI based WUSNs, and validate such solution approach by means of simulations. Third, this research is the first of its kind to explore novel communication concepts in the realm of MI based WUSNs, based on analogical thinking. Fourth, this research is the first of its kind to explore a novel longevity model in the realm of MI based WUSNs, based on analogical thinking. Fifth, this research is also the first to extend the notion of analogical thinking to futuristic directions in MI based WUSNs research, by means of providing possible indicators drawn from various other areas of contemporary research. In essence, the author believes that the findings of this research mark a paradigm shift in the research on MI based WUSNs

    A mobile applications innovation ecosystem framework for Botswana

    Get PDF
    Text in EnglishThe role that locally relevant services and content can play in the development of societies cannot be underestimated. The proliferation of mobile phones in Africa’s developing countries is a significant enabler, which provides access to such locally relevant services and content. Mobile applications have the potential to support the development of the African continent through bolstering the main mechanisms of innovation, inclusion and efficiency. This has been demonstrated by instances of increased literacy, improved access to health care, banking, crowd sourcing and provision of farming and/or agricultural assistance. Successful cases of such mobile-based services include Kenya’s M-Pesa, which has allowed millions of rural people, who do not have access to traditional banking facilities, to send and receive money as well as pay utility bills and school fees. The development of similar innovative and locally relevant mobile-based solutions, which is currently considered to be in its infancy, is key to improving the lives of people in developing countries. This study identifies the essential components of an innovation ecosystem, for the development and presentation of a Mobile Applications Innovation Ecosystem Framework for Botswana. An innovation ecosystem enables effective interaction amongst entrepreneurs, companies, universities, research organisations, investors and government agencies towards maximising economic impact and potential. To gain a practical understanding of the context in which locally relevant mobile-based services can be developed, the study adopted a pragmatic research approach. Through combining the 4Cs Framework for ICT and the systems theory’s Triple Helix Model of Innovation, the study proceeded to develop the framework using a Design Science Research (DSR) methodology. DSR guided the identification of the components, which make up the mobile applications innovation ecosystem within government, industry and higher education sectors, as extracted from the literature review. This process facilitated initial framework designs, which were demonstrated to and evaluated by conveniently sampled stakeholders from relevant helices. Thereafter a synthesised framework was presented for evaluation by knowledgeable professionals from the mobile applications innovation ecosystem. The study contributes to the theoretical knowledgebase by presenting a theoretical framework for understanding ICT4D innovation frameworks and mobile applicationsSchool of ComputingPh. D.

    Cyber-Physical Threat Intelligence for Critical Infrastructures Security

    Get PDF
    Modern critical infrastructures comprise of many interconnected cyber and physical assets, and as such are large scale cyber-physical systems. Hence, the conventional approach of securing these infrastructures by addressing cyber security and physical security separately is no longer effective. Rather more integrated approaches that address the security of cyber and physical assets at the same time are required. This book presents integrated (i.e. cyber and physical) security approaches and technologies for the critical infrastructures that underpin our societies. Specifically, it introduces advanced techniques for threat detection, risk assessment and security information sharing, based on leading edge technologies like machine learning, security knowledge modelling, IoT security and distributed ledger infrastructures. Likewise, it presets how established security technologies like Security Information and Event Management (SIEM), pen-testing, vulnerability assessment and security data analytics can be used in the context of integrated Critical Infrastructure Protection. The novel methods and techniques of the book are exemplified in case studies involving critical infrastructures in four industrial sectors, namely finance, healthcare, energy and communications. The peculiarities of critical infrastructure protection in each one of these sectors is discussed and addressed based on sector-specific solutions. The advent of the fourth industrial revolution (Industry 4.0) is expected to increase the cyber-physical nature of critical infrastructures as well as their interconnection in the scope of sectorial and cross-sector value chains. Therefore, the demand for solutions that foster the interplay between cyber and physical security, and enable Cyber-Physical Threat Intelligence is likely to explode. In this book, we have shed light on the structure of such integrated security systems, as well as on the technologies that will underpin their operation. We hope that Security and Critical Infrastructure Protection stakeholders will find the book useful when planning their future security strategies
