    A Novel Framework of an Expert System by integrating Capability Approach and BRB to Evaluate E-Government Services2015In: Proceedings of eChallenges e-2015 Conference / [ed] Paul Cunningham; Miriam Cunningham, IIMC International Information Management Corporation Ltd , 2015, p. 1-12, article id 68Conference paper (Refereed)
    Abstract [en]

    Capability approach is hard to operationalize and capabilities are sometimes difficult to reduce into the individual level. We describe our approach to solve these problems paired with an adequate ICT infrastructure and believe that the impact of concrete eGovernment services will become more visible and available. Citizens can inspect it, professionals can target their re-engineering on failure cases, learn from best cases, and researchers can compare different types of eGovernment. The solving of operationalisation will also strengthen the capability approach, by extending its scope from macro theory towards more easy application on the institutional and organizational levels.

    Disaster-resilient mobile network architecture2014In: Proceedings of the 2014 IEEE 11th Annual Consumer Communications & Networking Conference, Piscataway, NJ: IEEE Communications Society, 2014, p. 359-364Conference paper (Refereed)
    Abstract [en]

    Conventional cellular networks are likely to get disturbed easily when a natural disaster (earthquake, tsunami, flooding, etc.) hits an area because of their centralized control and high-power requirements. To address this issue, we propose a new mobile network architecture having distributed controls and ad-hoc configurations. This architecture exploits the locally available resources such as frequency spectrum and lively nodes to reconfigure the network and provide emergency services. We present its design and use cases.

    User toolkits for citizen-centric mobild service innovation2012In: eChallenges e-2012 Conference Proceedings / [ed] Paul Cunningham; Miriam Cunningham, IIMC International Information Management Corporation , 2012Conference paper (Refereed)
    Abstract [en]

    Around the world, there is an ongoing shift from en economy focusing on product development to an economy with focus on digital service development. An ongoing initiative in Europe to support this shift is the Internet of Services (IoS) which strives for a situation where everything that is needed to use a software is available as a service. The aim of this paper is to present a toolkit that non-programmers can use develop their own innovative mobile services. This environment strives to put forth a situation where technologies are made available as components that easily can be composed into a mobile services by just about anyone. This has tremendous impact on the feasibility of citizen-centric services where citizens create apps based on their current needs in their contemporary situation.

    Concept design with a living lab approach2009In: 2009 42nd Hawaii International Conference on System Sciences: HICSS ; Waikoloa, Hawaii, 5 - 8 January 20 / [ed] Ralph H Sprague Jr, IEEE Communications Society, 2009, p. 1-10Conference paper (Refereed)
    Abstract [en]

    Living Labs is a rather new research area and phenomena that introduces new ways of managing innovation processes. The underlying idea is that people's ideas, experiences, and knowledge, as well as their daily needs of support from products, services, or applications, should be the starting point in innovation. This paper illuminates experiences and accumulated knowledge to the area of concept design in an innovation process within a Living Lab. FormIT, a methodology developed for innovation processes within Living Labs is introduced through an illustration of how it has been utilised in a case. The experiences and the method are related to characteristics of Living Labs, and the paper closes with some concluding remarks in relation to concept design in a Living Lab.

    Creating a new leverage point for information systems development2008In: Designing information and organisations with a positive lens, Amsterdam: JAI Press Ltd, 2008, p. 75-95Chapter in book (Other academic)
    Abstract [en]

    We present a new approach that shifts the leverage point of information systems development from problem orientation to opportunity development. Our approach, entitled FormIT, employs a careful focus on enhanced user involvement, concentrating on users as human beings, and attention to users’ needs as opposed to system requirements. As theoretical and methodological foundations, we build on the 4-D cycle model of Appreciative Inquiry and current research on needfinding. Our field experience demonstrates that FormIT shifts the systems development process from being reactive to being proactive, and in turn, enables a smoother implementation of inevitable change, particularly radical change. Moreover, FormIT stimulates the generation of rich local knowledge and helps reveal deep insights into the development process and the overall organization.

    Mobile computing application for industrial field service engineering: a case for ABB service engineers2013In: Proceedings of the 38th IEEE Conference on Local Computer Networks Workshops (LCN Workshops): 7th IEEE Workshop On User MObility and VEhicular Networks / [ed] Damla Turgut; Nils Aschenbruck; Jens Tölle, Piscataway, NJ: IEEE Computer Society Press , 2013, p. 188-193Conference paper (Refereed)
    Abstract [en]

    The increasing digitalization of our daily lives is gaining a new momentum recently in what is called the post- desktop era of computing. This wide spread in digitalization is made possible by the introduction of handy devices specifically of mobile phones, laptop computers, smartphones, and tablets. This new trend in shaping up technological advancement presents new opportunities for mobile information presentation, processing, and synthesis in different spheres of application such as providing industrial field services engineering support. Industrial field service engineers execute sets of work orders on daily basis plans. These work order executions demand the availability of digital information anywhere anytime to process them faster. This paper presents a scenario where the newly emerging Smartphone features such as augmented reality, audio/video processing, and near field communication sensing can be used to develop a prototype that supports industrial field service engineers in the contemporary field service engineering taskforces. It employs real world use-cases and carrying out quantitative prototype usability test analysis.

    Elimination of DoS UDP Reflection Amplification Bandwidth Attacks, Protecting TCP Services2015In: Future Network Systems and Security: First International Conference, FNSS 2015, Paris, France, June 11-13, 2015, Proceedings / [ed] Robin Doss; Selwyn Piramuthu; Wei Zhou, Encyclopedia of Global Archaeology/Springer Verlag, 2015, p. 1-15Conference paper (Refereed)
    Abstract [en]

    In this paper, we propose a solution to eliminate a popular type of Denial of Service (DoS) attack, which is a DoS amplification attack. Note that a DoS is a subset of of DDoS. Our solution protects servers running any number of TCP services. This paper is focused on the most popular type of DoS amplification attack, which uses the UDP protocol. Via DoS UDP amplification attacks, an attacker can send a 1 Gbps traffic stream to reflectors. The reflectors will then send up 556 times that amount (amplified traffic) to the victim’s server. So just ten PCs, each sending 10Mbps, can send 55 Gbps indirectly, via reflectors, to a victim’s server. Very few ISP customers have 55 Gpbs provisioned. Expensive and complex solutions exist. However our elimination techniques can be implemented very quickly, easily and at an extremely low cost.

    Network DDoS Layer 3/4/7 Mitigation via Dynamic Web Redirection2016In: Future Network Systems and Security: Second International Conference, FNSS 2016, Paris, France, November 23-25, 2016, Proceedings / [ed] Robin Doss, Selwyn Piramuthu, Wei Zhou, New York: Springer, 2016, p. 111-125Conference paper (Refereed)
    Abstract [en]

    Layer 3, 4 and 7 DDoS attacks are common and very difficult to defend against. The academic community has published hundreds of well thought out algorithms, which require changes in computer networking equipment, to better detect and mitigate these attacks. The problem with these solutions, is that they require computer networking manufacturers to make changes to their hardware and/or software. On the other hand, with our solution, absolutely no hardware or software changes are required. We only require the use of BGP4 Flow-Spec, which has already been widely deployed many years ago. Further the customers’ own ISP does not require Flow-Spec. Our algorithm protects groups of over sixty-five thousand different customers, via the aggregation into one very small Flow-Spec rule. In this paper, we propose our novel, low cost and efficient solution, to both detect and greatly mitigate any and all types of L347 DDoS Web attacks.

    Network Security of Internet Services: Eliminate DDoS Reflection Amplification Attacks2015In: Journal of Internet Services and Information Security (JISIS), ISSN 2182-2069, E-ISSN 2182-2077, Vol. 5, no 3, p. 58-79, article id 5Article in journal (Refereed)
    Abstract [en]

    Our research problem is that there are a large number of successful network reflection DDoS attacks. Via a UDP Reflection Attack, an attacker can send just 1 Gb/s of payload to innocent servers, and it is these servers which then can send over 4,600 times the payload to the victim! There are very expensive and complex solutions in use today, however most all of these on premise solutions can be easily circumvented. The academic community has not adequately addressed this research problem. We have created a new Internet services network security surface attack mitigation methodology. Our novel design patterns will help organizations improve the price/performance of their anti-network reflection solution by 100 times, as compared to common on premise solutions. Our analysis and results confirm that our solution is viable. Our novel solution is based on stateless IP packet header filtering firewalls (which can be implemented mostly in hardware due to their simplicity). We have reduced and in some cases eliminated the need for researchers to even try and find new ways to filter the same traffic via more complex, software driven stateful solutions.

    Enabling crowd-sourcing-based privacy risk assessment in EU: the privacy flag project2017In: PCI 2017: Proceedings of the 21st Pan-Hellenic Conference on Informatics, New York: ACM Digital Library, 2017, Vol. F132523, article id 31Conference paper (Refereed)
    Abstract [en]

    Personal data have become merchandisable asset encouraging stakeholders to collect and trade them without end-user's awareness and acceptance. Although EU is adapting the legal framework, the extent of applications most of which are developed from outside the EU jurisdiction, strongly limit the possibility to effectively impose a privacy-protection framework globally. The Privacy Rag project researches and combines the potential of crowds ourcing, ICT technologies and legal expertise for enabling citizens monitoring and controlling their privacy1.

    A user driven approach to develop a cognitive prosthetic to address the unmet needs of people with mild dementia2009In: Pervasive and Mobile Computing, ISSN 1574-1192, E-ISSN 1873-1589, Vol. 5, no 3, p. 253-267Article in journal (Refereed)
    Abstract [en]

    This paper aims to provide the details of the approach adopted in the development of a cognitive prosthetic aimed to help address the unmet needs of people with mild dementia. The approach adopted is based on a waterfall style approach consisting of a series of three phases each of which contributes to the progression and improvement of a cognitive prosthetic-based solution. Within each phase, distinct stages of design, development and evaluation of the cognitive solution are conducted. The current paper discusses the distinct stages conducted in the first phase of the project which resulted in the design and development of a user driven solution based on the needs of 17 patient/carer dyads across three trial sites.

    Low-loss TCP/IP header compression for wireless networks1996In: Proceedings of the annual international conference on mobile computing and networking ; 2nd: MOBICOM'96, IEEE Communications Society, 1996, p. 1-14Conference paper (Refereed)
    Abstract [en]

    Wireless is becoming a popular way to connect mobile computers to the Internet and other networks. The bandwidth of wireless links will probably always be limited due to properties of the physical medium and regulatory limits on the use of frequencies for radio communication. Therefore, it is necessary for network protocols to utilize the available bandwidth efficiently. Headers of IP packets are growing and the bandwidth required for transmitting headers is increasing. With the coming of IPv6 the address size increases from 4 to 16 bytes and the basic IP header increases from 20 to 40 bytes. Moreover, most mobility schemes tunnel packets addressed to mobile hosts by adding an extra IP header or extra routing information, typically increasing the size of TCP/IPv4 headers to 60 bytes and TCP/IPv6 headers to 100 bytes. In this paper, we provide new header compression schemes for UDP/IP and TCP/IP protocols. We show how to reduce the size of UDP/IP headers by an order of magnitude, down t...

    Issues in the design of a new network protocol1996In: Multimedia Telecommunications and Applications: Third International COST 237 Workshop Barcelona, Spain, November 25-27, 1996 Proceedings / [ed] Giorgio Ventre, Berlin: Encyclopedia of Global Archaeology/Springer Verlag, 1996, p. 169-182Conference paper (Refereed)
    Abstract [en]

    We describe some of the issues in the design of a new packet switched network protocol. Adaptation to various network technologies along the dimensions of speed, error model, robustness, etc., is a goal for this new protocol. We look at the adaption in size of the packet header to the speed and robustness of the underlying network to allow efficient communication on low-speed wireless networks, for example. We also explore issues in resource reservation and multicast for real-time multimedia, the notion of a network "flow", a hybrid of datagrams and virtual circuits, and suggest common solutions for both mobile and multicast routing. The authors are engaged in the design of a network protocol, NP++, whose goal is flexibility over a wide dynamic range of speeds and varying kinds of hardware switching elements.

    A very brief guide to Internet Governance and the emerging organization of multi stakeholder participation2006Report (Other academic)
    Abstract [en]

    One result of the 4 year World Summit on Information Society (WSIS) was the formation of the multistakeholder Internet Governance Forum (IGF). This forum is a radically new form of organization for the UN as it allows for participation by the various stakeholders of the Internet, as opposed to being restricted to government representatives. Internet governance is a relatively new area of discourse that is becoming a hot issue of international dialogue. This paper briefly discusses the origins of the debate and the meaning of Internet Governance as well as outlining some of the ongoing activities in this area. The paper also discusses some ways in which the reader can get involved in the debate and why they may want to.

    Towards a manifesto for living lab co-creation2009In: Human-Computer Interaction - INTERACT 2009: 12th IFIP TC 13 International Conference, Uppsala, Sweden, August 24-28, 2009, Proceedings / [ed] Tom Gross, Berlin: Encyclopedia of Global Archaeology/Springer Verlag, 2009, Vol. 2, p. 979-980Conference paper (Refereed)
    Abstract [en]

    There is a growing interest in Living Labs for innovation and development in the field of information and communication technology. In particular there seem to be a tendency that current Living Labs aim to involve users for co-creative purposes. However, the current literature on Living Lab co-creation is severely limited. Therefore an Interact workshop is arranged as a first step towards a manifesto for Living Lab co-creation.

    Abstract [en]

    In this paper we present a case study of a location-dependent service, aimed for tourists. Two applications are developed, one based on native technologies, the other on HTML5 and related frameworks. We provide implementation details and compare the different solutions in terms of location support, compliance with required features, and cross-platform functionality. Our experiments show that web-based approaches may lead to significant benefits over using native technologies; both versions of the application displayed comparable location support and compliance with required features, while the web version superseded its native counterpart in cross-platform functionality.

    Abstract [sv]

    Från ansökan: "Projektet skall via användarmedverkan, med skolungdomar och lärare på Tunaskolan i Luleå, kombinerat med smart IT och design av nya innovativa sätt för visualisering utveckla nya metoder för att minska energiförbrukningen. Projektet bygger vidare på resultat och samarbeten med både nationella och internationella EU projekt inom området energibesparing med fokus på användarmedverkan.Vi vill tillsammans med skolungdomar, morgondagens beslutsfattare, och via deras "normala" kommunikationsvägar (Internet, Web 2.0, Facebook etc) sprida och engagera om energi och miljö. Genom att bygga demonstratorer vill vi lära oss hur och vad man bör fokusera på för att både spara energi men även bidra till en större medvetenhet för områdena. Vi vet att ungdomar idag mycket snabbare sprider "god" information och huvudfokus för projektet är att tillsammans med ungdomarna förstå vad och på vilket sätt energiutnyttjandet skall visualiseras för att "nå ut" och spridas.Vårt mål är att engagera skolan, elever, lärare och besökare, till att bidra med idéer för hur man kan spara energi och värna om miljön. Tillsammans med projektdeltagarna kommer nya Internet-baserade applikationer attutvecklas för visualisering av i realtid uppmätt energiutnyttjande. Tillvägagångssättet kommer vara baserat på att genom korta och snabba iterationer sätta nya versioner av de utvecklade applikationerna "i händerna" påungdomarna som varit med och designat själva hur applikationerna ska se ut för att presentera energiförbrukning på ett enkelt sätt.Vi avser också att via medverkande företag, baserat på resultat i projektet, utveckla nya affärer och vi kommer kontinuerligt under projektet att sprida information om framsteg via Internet, konferenser samt andra samarbetsprojekt.

    Action research supported implementation of a crisis competence centre2009In: ISCRAM 2009: 6th international conference on information systems for crisis response and management : boundary spanning initiatives and new perspectives : Gothenburg, Sweden 10th - 13th of May / [ed] J. Landgren; U. Nulden; B. Van de Walle, Göteborg, 2009Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to describe the development of a regional crisis competence centre in Sweden. The overall research approach utilizes action research methodology to support the development process. The overall development process is divided into three steps; early need finding, the organizational platform, and business development. This paper is devoted to the first phase - early need finding - which deals with the specific needs and demand of four municipality organizations and how these requirements can be converged into a organizational setting that correspond to national crisis management strategies as well as regional responsibilities in crisis management. The research approach is action based and the theoretical considerations to support progress in development activities are from the Actor Network Theory (ANT). The main conclusion from the research is that the formation of a crisis competence centre revolves around sharing competences, and compromising between internal and external objectives in the progress towards a common goal.

    Abstract [en]

    Smart cities have been recently pointed out by M2M experts as an emerging market with enormous potential, which is expected to drive the digital economy forward in the coming years. However, most of the current city and urban developments are based on vertical ICT solutions leading to an unsustainable sea of systems and market islands. In this work we discuss how the recent vision of the Future Internet (FI), and its particular components, Internet of Things (IoT) and Internet of Services (IoS), can become building blocks to progress towards a unified urban-scale ICT platform transforming a Smart City into an open innovation platform. Moreover, we present some results of generic implementations based on the ITU-T’s Ubiquitous Sensor Network (USN) model. The referenced platform model fulfills basic principles of open, federated and trusted platforms (FOTs) at two different levels: the infrastructure level (IoT to support the complexity of heterogeneous sensors deployed in urban spaces), and at the service level (IoS as a suit of open and standardized enablers to facilitate the composition of interoperable smart city services). We also discuss the need of infrastructures at the European level for a realistic large-scale experimentally-driven research, and present main principles of the unique-in-the-world experimental test facility under development within the SmartSantander EU project.

    Enabling boundary-crossing collaboration for innovation: issues for collaborative working environments2007Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In this thesis, boundary-crossing collaborative knowledge work aiming for innovation and use of ICT is in focus. The starting point for the research was the proposition that we still have much to learn about boundary- crossing collaboration for innovation and the use of ICT before we can design enabling and supporting ICT and collaborative working environments. Thus, the purpose has been to study and understand collaborative boundary- crossing working groups' activities, as a way to extend the possibilities to design enabling and supporting ICT. To meet this purpose, I wanted to answer the question: How can boundary-crossing collaboration aiming for innovation be enabled in collaborative working environments? Three case studies, with somewhat different focuses, methods and also results, have been performed. Different models as frameworks for both analysis and design have been used in the cases. Main conclusions and contributions of the thesis are given as lessons learned, related to four main areas which were identified from analysis of case data. The first set of conclusions is related to processes and factors enabling knowledge work across boundaries. These are: application of energizing factors, use of boundary objects, addressing roles, norms, values and knowledge assets and, finally, creating dedicated places and spaces. The second set of conclusions is related to ICT issues in boundary- crossing knowledge work. These are: choice of technology, shared virtual platform and models for appreciating technology needs. The third set of conclusions is related to the importance of appreciation of user needs, and methods for this, in the process of designing or developing a collaborative working environment. The fourth set of conclusions comes in the form of reflections on the theoretical models that have been used during the research. There is a need for models and methods that enable design of collaborative environments, as well as models and methods that enable this to be done from a user needs perspective. From the lessons learned, some overarching reflections on implications for collaborative working environments are made. Hence, implications for CWEs as a whole, and some ideas on future research, are presented in the form of a tentative model which can be viewed as a model for designing group processes and relevant technology in a CWE. In this model, designing a CWE and its processes imply more that just designing technology. To conclude, the thesis contributes to the understanding of organisational processes for boundary-crossing collaborative knowledge work through lessons learned, which, in turn, give implications for CWEs.

    Abstract [en]

    The main issues addressed by APOLLON are the present lack of Living Lab harmonisation and collaboration, and the serious difficulties of SMEs in engaging in cross-border innovation. APOLLON will demonstrate the positive impacts of cross-border domain-specific Living Lab networks, by setting up an advanced pilot composed of 4 thematically focused European-wide Living Lab experiments. In the experiments, SMEs are enabled to take part in cross-border Living Lab experiments beyond their home markets, and are supported by large industrial companies, academic centres and other stakeholders. The APOLLON pilot aims at the sharing and harmonisation of Living Lab approaches and platforms between networks of exemplary European Living Labs, and the subsequent evaluation results and the set up of sustainable domain-specific networks on a European and global level. APOLLON addresses 4 major domains in which ICT products and services innovation may benefit most from cross-border Living Lab networking. These are: (1) Homecare and Independent Living, (2) Energy Efficiency, (3) eManufacturing and (4) eParticipation.

    Framing multidisciplinary teams: sense making through the POM model2006In: Integrating Visions of Technology: Proceedings of the 12th Annual Working Conference of CPTS / [ed] Andrew Basden; Anita Mirijamdotter; Sytse Strijbos, CPTS , 2006, p. 111-140Conference paper (Refereed)
    Abstract [en]

    In this paper we focus on Living Labs for promoting and developing collaborative working environments (CWEs). The issues we address in this context are related to knowledge-sharing for innovation. More precisely we explore methodologies for appreciative inquiry that stimulate creativity and facilitate the process for co-creative needfinding and innovation. Additionally we contribute to a European state-of-the-art in utilizing Living Labs to user-centric ICT innovation and to establishing a foundation for a European Network of Living Labs. A pan-European Network of Living Labs brings the extreme benefit of leveraging the concept of a Europe of Regions. However, when interactions are conducted at a distance across organisational, geographical and cultural boundaries, placing at risk the overall competiveness of an organisation, the challenge is to develop tools, methods, and work-practices to manage this interaction. This is the aim of this research. The context and content for this paper is transformation processes in higher education in which knowledge from distinct disciplines are integrated into new multidisciplinary education and research. Checkland's and Holwell's model of Process for Organisational Meanings (POM) is used to present and appreciate the efficacy of these set-up processes. The POM-model is found to be useful for making sense of design work across boundaries and for identifying best practices as it visually represents the important processes of making meaning by interactions among participants in various organisational settings and by means of technology. The results of the study point to best practices for creating shared vision across disciplinary boundaries. Shared visions enable knowledge creation and integration, in turn generating common ground for aligned action and design. Important insights for how to cultivate the fragile processes of setting up multidisciplinary teams are currently lacking. Hence, the findings from this study contribute to set up of multidisciplinary teams successfully. Aware of the start up issues, chances of successful implementation will be enhanced.

    This paper explicates the process of expanding and enriching need-finding through narrative inquiry. In this way we are able to identify needs and, thus, facilitate the design process of a knowledge community and its virtual spaces for knowledgesharing and creation across boundaries among young entrepreneurs. The specific situation which the design of a knowledge community constitute is discussed and the usefulness of our approach is thereafter valued in relation to the challenges of creating a viable community constructed from participants' identified needs and interests

    Openness in living labs: facilitating innovation2010In: Proceedings of the 33rd IRIS Seminar, 2010Conference paper (Refereed)
    Abstract [en]

    Innovation has come to replace efficiency and quality as the main source of competitive advantage for firms from the 1990s onwards. Hence, to an increasing extent, organisations need to consider in which ways they can achieve higher levels of innovative thinking and flexibility. Moreover, the creation of today's complex systems of products, services and processes requires a merging of knowledge from diverse perspectives, e.g. disciplinary or skill-based. One common way to meet these challenges is to set up boundary crossing collaborative groups. The idea is that innovative processes can be fertilised by having people with differentiated knowledge collaborating. Knowledge necessary for innovation and product/service development is, therefore, increasingly distributed both within and across organisations or other types of stakeholders, posing new challenges. To manage these challenges one new approach is evolving, called Living Labs. In this paper we present an innovative development process of a mobile service, taking a Living Lab approach. This paper focus on the effects of openness in an innovation process supported by a Living Lab approach for development of mobile services. The study shows that the innovation process was remarkably shortened in the open and multi-perspective process.

    A Belief Rule Based Expert System to Diagnose Measles under Uncertainty2015In: Proceedings of the 2015 International Conference on Health Informatics and Medical Systems (HIMS'15) / [ed] Hamid R. Arabnia; Leonidas Deligiannidis; George Jandieri; Ashu M. G. Solo; Fernando G. Tinetti, CSREA Press, 2015, p. 17-23Conference paper (Refereed)
    Abstract [en]

    Measles is a highly infectious child disease that causes serious complications and death worldwide. Measles is generally diagnosed from its signs and symptoms by a physician, which cannot be measured with 100% certainty during the diagnosis process. Consequently, the traditional way of diagnosing measles from its signs and symptoms lacks the accuracy. Therefore, a belief rule-based inference methodology using evidential reasoning approach (RIMER), which is capable of handling various types of uncertainties has been used to develop an expert system to diagnose measles under uncertainty. The results, generated, from the system have been compared with the expert opinion as well as with a Fuzzy Logic based system. In both the cases, it has been found that the Belief Rule Based Expert (BRBES), presented in this paper, is more reliable and accurate.

    A Two Filter Particle Smoother for Wiener State-Space Systems2015In: 2015 IEEE International Conference on Control Applications (CCA 2015): Sydney, Australia, September 21-23 2015, Piscataway, NJ: IEEE Communications Society, 2015, p. 412-417, article id 7320664Conference paper (Refereed)
    Abstract [en]

    In this article, a two filter particle smoothing algorithm for Wiener state-space systems is proposed. The smoother is obtained by exploiting the model structure. This leads to a suitable proposal density for the backward filter inherent in the problem instead of introducing an artificial one. Numerical examples are provided in order to illustrate the proposed algorithm's performance and to compare it to current state of the art smoothers from the literature. It is found that the proposed method yields comparable results with less computational complexity as backward simulation-based particle smoothing algorithms.

    A Web Based Belief Rule Based Expert System to Predict Flood2015In: Proceedings of the 17th International Conference on Information Integration and Web-based Applications & Services (iiWAS2015) / [ed] Maria Indrawan-Santiago; Matthias Steinbauer; Ismail Khalil; Gabriele Anderst-Kotsis, New York: Association for Computing Machinery (ACM), 2015, p. 19-26, article id 3Conference paper (Refereed)
    Abstract [en]

    Natural calamity disrupts our daily life and brings many sufferings in our life. Among the natural calamities, flood is one of the most catastrophic. Predicting flood helps us to take necessary precautions and save human lives. Several types of data (meteorological condition, topography, river characteristics, and human activities) are used to predict flood water level in an area. In our previous works, we proposed a belief rule based flood prediction system in a desktop environment. In this paper, we propose a web-service based flood prediction expert system by incorporating belief rule base with the capability of reading sensor data such as rainfall, river flow on real time basis. This will facilitate the monitoring of the various flood-intensifying factors, contributing in increasing the flood water level in an area. Eventually, the decision makers would able to take measures to control those factors and to reduce the intensity of flooding in an area.

    Secure and scalable multimedia sharing between smart homes2014In: Journal of Wireless Mobile Networks, Ubiquitous Computing, and Dependable Applications, ISSN 2093-5374, E-ISSN 2093-5382, Vol. 5, no 3, p. 79-93, article id 6Article in journal (Refereed)
    Abstract [en]

    The smartphone revolution together with cost-efficient wireless access technologies have lately changed the landscape for smart home environments to a large extent. Moreover, large flat screens, new capturing devices, and large digital media libraries have also changed the way smart home environments are used. We present and evaluate an architecture for multimedia sharing in such environments. End-users can, by authenticating their terminals with a node in the home or visited environment easily gain access to various types of resources at home while roaming to other people's home networks. This is achieved by using the infrastructure provided by the operator.
