    IoT-based information system for healthcare application: Design methodology approach2017In: Applied Sciences, ISSN 2076-3417, Vol. - 7, no - 6, 596Article in journal (Refereed)
    Abstract [en]

    - Over the last few decades, life expectancy has increased significantly. However, elderly people who live on their own often need assistance due to mobility difficulties, symptoms of dementia or other health problems. In such cases, an autonomous supporting system may be helpful. This paper proposes the Internet of Things (IoT)-based information system for indoor and outdoor use. Since the conducted survey of related works indicated a lack of methodological approaches to the design process, therefore a Design Methodology (DM), which approaches the design target from the perspective of the stakeholders, contracting authorities and potential users, is introduced. The implemented solution applies the three-axial accelerometer and magnetometer, Pedestrian Dead Reckoning (PDR), thresholding and the decision trees algorithm. Such an architecture enables the localization of a monitored person within four room-zones with accuracy; furthermore, it identifies falls and the activities of lying, standing, sitting and walking. Based on the identified activities, the system classifies current activities as normal, suspicious or dangerous, which is used to notify the healthcare staff about possible problems. The real-life scenarios validated the high robustness of the proposed solution. Moreover, the test results satisfied both stakeholders and future users and ensured further cooperation with the project. © 2017 by the authors.

    Data Mining in Product Service Systems Design: Literature Review and Research Questions2017In: Procedia CIRP. / [ed] Tim C. McAloone, Daniela C.A. Pigosso, Niels Henrik Mortensen and Yoshiki Shimomura, Elsevier, 2017, Vol. 64, 306-311 p.Conference paper (Refereed)
    Abstract [en]

    The paper presents a literature review about data mining applications in Product/Service-Systems (PSS) design. A systematic literature review, combined with snowballing techniques, has been run to identify relevant contributions in the area. The analysis has focused on the categorization of the contributions according to their impact on the PSS design process and according to their theoretical or empirical nature. A picture of the different research achievements for each stage of the PSS design process have been drawn, identifying the research gaps in respect to the challenges of PSS design. Based on the analysis the paper proposes a set of research questions for each PSS design stage with the intent of facilitating the application of data mining techniques in PSS design, and ultimately push forward the state of the art.

    Abstract [en]

    Global society is encountering many challenges such as climate change, resource depletion, etc., which comes with a set of challenges and opportunities for businesses. Applied research in operational tools and methods that support sustainable product- and service systems innovation, aims to strengthen businesses to overcome these challenges. In recent years, several tools and methods have been developed in the sustainable product development field with focus on modelling and digitalization. This paper explores how sustainability has been integrated in modelling and simulation, and presents results from a literature review with the purpose of highlighting opportunities and challenges in the field. Furthermore, an initial model-based engineering support toolbox (MBE) is presented, with focus on support tools for socio-ecological sustainability integration in the early product development stages.

    Measuring Docker Performance: What a Mess!!!2017In: ICPE 2017 - Companion of the 2017 ACM/SPEC International Conference on Performance Engineering, ACM , 2017, 11-16 p.Conference paper (Refereed)
    Abstract [en]

    Today, a new technology is going to change the way platforms for the internet of services are designed and managed. This technology is called container (e.g. Docker and LXC). The internet of service industry is adopting the container technology both for internal usage and as commercial offering. The use of container as base technology for large-scale systems opens many challenges in the area of resource management at run-time, for example: autoscaling, optimal deployment and monitoring. Specifically, monitoring of container based systems is at the ground of any resource management solution, and it is the focus of this work. This paper explores the tools available to measure the performance of Docker from the perspective of the host operating system and of the virtualization environment, and it provides a characterization of the CPU and disk I/O overhead introduced by containers.

    Introducing Sustainability in Value Models to Support Design Decision Making: A Systematic Review2017In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 9, no 6, 994Article in journal (Refereed)
    Abstract [en]

    Manufacturing organizations shall recognize sustainability as a business occasion to capitalize on, rather than an undesirable pressing situation. Still, empirical evidence shows that this opportunity is hard to capture and communicate in global strategic decisions, through planning by tactical management, to daily operational activities. This paper systematically reviews the modeling challenges at the crossroad of value and sustainability decisions making, spotlighting methods and tools proposed in literature to link sustainability to customer value creation at strategic, tactical and operational level. While statistical results show that the topic of sustainability and value modeling is trending in literature, findings from content analysis reveal that recent attempts to promote a value-based view in the sustainability discussion remain at a strategic level, with most of the proposed indicators being suited for managerial decision-making. The lack of support at operational level points to the opportunity of cross-pollinating sustainability research with value-centered methodologies originating from the aerospace sector. The Value Driven Design framework is proposed as main hub from which to derive models supporting engineers and technology developers in the identification of win-win-win situations, where sustainable improvements are aligned with business advantages.

    Simulation-driven design for assessing strategic decisions in the conceptual design of circular PSS business models2017In: Procedia CIRP: The 9th CIRP IPSS Conference: Circular Perspectives on Product/Service-Systems, Elsevier, 2017, Vol. 64, 25-30 p.Conference paper (Refereed)
    Abstract [en]

    Due to ever increasing challenges faced by our global society, circular design and the idea of product-service systems (PSS) isgaining traction within businesses. However, ‘predicting’ the value of a future PSS solution in the early design phases is difficult,since it requires the ability to balance long term potential with short term decisions. Modelling and simulation is believed to beable to support this challenging task. A simulation framework for circular design of PSS is presented. The simulation processenables the comparison between functional and non-functional performances and their life cycle contributions depending on adefined PSS-like business model strategy. Such integrated simulation framework is intended to exploit engineering modelsoutside their specific discipline, enabling cross-functional collaboration and help decision makers understand how a design cancontribute in satisfying customer and stakeholders needs during the lifecycle of a PSS.

    Product-Service Systems for Functional Offering of Automotive Fixtures: Using Design Automation as Enabler2017In: Procedia CIRP: 9th CIRP Conference on Industrial Product/Service-Systems (IPSS), Copenhagen, Elsevier, 2017, Vol. 64, 411-416 p.Conference paper (Refereed)
    Abstract [en]

    In production of automotive components, control-measuring is an important activity to assure that geometries meet expected tolerances. This is done via randomly taking parts out of production for control-measuring in a fixture. This fixture is both a tedious and repetitive product to design and configure. The aim of this paper is therefore to present an approach to adopt a design automation strategy towards supporting the configuration of fixtures and to discuss opportunities for moving towards a Product-Service System-paradigm in this domain. This paper reports on a development of a design automation demonstrator to configure fixtures for control-measuring. The demonstrator has been developed in a commercial CAD-environment and will be deployed through a web-based interface. The paper concludes with a discussion on PSS-opportunities and how to drive this with a Knowledge-Based Engineering-modelling approach.

    Barn och ungdomar med rörelsehinder: deras uppfattningar om roller, relationer och aktiviteter2002Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The general aim of this thesis was to describe how children and adolescents with restricted mobility perceived their roles, relations and activities in relation to peers and adults in different settings. The thesis includes six sub-studies, which are based on interviews, observations and field notes with children and adolescents with restricted mobility aged from 6 to 19 years. Using Bronfenbrenner’s theory “the Ecology of Human Development” as the main theoretical framework, the ambition was to understand the children and adolescents’ social world from their perspective. The principal finding was the lack of peers in the children and adolescents’ social network. Furthermore, this tendency of isolation from peers was found to increase during the transition from childhood to adolescence. Their relationships to peers were strained and activities and surroundings in which social contacts could develop were limited. The relationships with peers were also characterised by social barriers in the form of attitudes that resulted in social isolation from the group of persons the disabled children and adolescents most wished to be with. When relations to peers were limited, the disabled children’s social life was restricted to adults. The results further showed that the children and adolescents’ roles and relations often were significantly different from their peers. The children and adolescents’ arrived at a concept of themselves that differed from the way others conceptually saw them. Furthermore, the children and adolescents saw themselves as regular members of their peer group, but the other members of the peer group saw them as different from themselves. Relationships to friends of the same age either were confined or were nonexistent. Relationships to adults were often characterised as ambivalent or asymmetric, i.e. the adults were helpful and supportive while over protective and dominant at the same time. The thesis revealed that, despite the many obstacles facing them, the children and adolescents with restricted mobility had a positive view of their future.

    Men's experiences of giving and taking social support after their wife's spinal cord injury2008In: Scandinavian Journal of Occupational Therapy, ISSN 1103-8128, E-ISSN 1651-2014, Vol. 15, no 4, 236-246 p.Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to gain an understanding of how men living with women with spinal cord injury (SCI) experienced and acted when they were giving and taking social support to and from their wives and other persons in their social network. Another aim was to give some possible explanations of the complex process of change that they went through. Data were collected through in-depth interviews with four men and field notes. To describe the men's subjective experiences and the process of change, a narrative approach inspired by Polkinghorne was used. The analyses resulted in one story that included the four men's experiences and action. The story showed that when the men went through a process of change, they used and needed both emotional and practical support to handle their new life situation. Furthermore, the men's experiences and action against social support changed over time. This indicated that, through narratives from spouses, professionals within rehabilitation could understand the process of change they went through after their partner's sudden injury, and support them to find strategies to handle their changed life situation. To give some possible explanations for the men's experiences and action during the process of change, the findings are discussed in relation to theories concerning adaptation and coping

    Living with a double burden: Meanings of pain for women with fibromyalgia2011In: International Journal of Qualitative Studies on Health and Well-being, ISSN 1748-2623, E-ISSN 1748-2631, Vol. 6, no 3Article in journal (Refereed)
    Abstract [en]

    Living with fibromyalgia (FM) means living with a chronic pain condition that greatly influences daily life. The majority of people with FM are middle-aged women. The aim of this study was to elucidate meanings of pain for women with FM. Fifteen women with FM were interviewed about their pain experiences and a phenomenological hermeneutic interpretation was used to analyse the interview texts. The findings show that meanings of pain for women with FM can be understood as living with a double burden; living with an aggressive, unpredictable pain and being doubted by others in relation to the invisible pain. The ever-present pain was described as unbearable, overwhelming, and dominated the women’s whole existence. Nevertheless, all the women tried to normalize life by doing daily chores in an attempt to alleviate the pain. In order to support the women’s needs and help them to feel well despite their pain, it is important that nurses and health care personnel acknowledge and understand women with FM and their pain experiences.

    Swedish district nurses' attitudes to implement information and communication technology in home nursing2008In: Open Nursing Journal, ISSN 1874-4346, E-ISSN 1874-4346, Vol. 2, 68-72 p.Article in journal (Refereed)
    Abstract [en]

    The use of information and communication technology has increased in the society, and can be useful in nursing care. The aim of this study was to describe district nurses' attitudes regarding the implementation of information and communication technology in home nursing. The first and third authors performed five focus group discussions with 19 district nurses' from five primary healthcare centres in northern Sweden. During the focus group discussions, the following topics were discussed: the current and future use of information and communication technology in home nursing; expectations, advantages, disadvantages and hindrances in the use of information and communication technology in home nursing; and the use of information and communication technology from an ethical perspective. The transcribed focus group discussions were analysed using qualitative content analysis. The results showed that district nurses' attitudes were positive regarding the use of information and communication technology in their work. They also asked for possibilities to influence the design and its introduction. However, the use of information and communication technology in home nursing can be described as a complement to communication that could not replace human physical encounters. Improvements and risks, as well as the importance of physical presence in home nursing were considered vital. The results revealed that the use of information and communication technology requires changes in the district nurses' work situation.
