    Prototyping for Product-Service Systems innovation: Insights from the construction equipment industry2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    To radically increase the value delivered to the customers in the construction industry a concerted effort is needed to develop solutions beyond incremental adjustments. Simply providing add-on services to existing products does not effectively create solutions with enough gains in core customer values. Designing and developing a product service system (PSS) through the adjustment or reconfiguration of existing elements is a challenge on its own, and adding the design of new elements serves to confound the process even further. By realigning all components of a PSS from inception to a function provides an opportunity to escape current product limitations and explore new solutions with potentially higher value. Designing a new PSS solution from scratch comes with added ambiguity in an expanded solution space.

    The aim of this thesis is to investigate early conceptual phases of PSS innovation within the domain of construction equipment manufacturing. The research included the development and testing of a prototyping method to foster customer co-creation and transdisciplinary design which are considered primary impact factors increasing the value of final PSS solutions.

    The work was performed in collaboration with a construction equipment manufacturer, conducting a demonstrator project on an electric and autonomous production site. The thesis first depicts how the prototyping method can be implemented to enable stakeholder insights that were previously not accessible through current practices. This leads to the testing of the method in a broader perspective to represent tangible and intangible elements in a way that facilitates concept design decisions in multi-disciplinary settings. The thesis concludes by exploring the limitations on current practices in relation to the adoption and potential use of the method.

    Inviting Community into the Development of Globally Sustainable Food Systems2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Food systems and human diets contribute to unsustainable socioecological conditions, which in turn negatively affect human health. These driver-impact relationships span multiple scales, prompting international governance bodies, nations, and communities alike to grapple with solutions for a better food future. Collaborative action across scales and sectors is necessary; however, how communities can align contributions with efforts at broader scales is unclear.

    The aim of this research is to develop theoretical and procedural supports for community engagement in globally sustainable food systems (SFS), and to provide concrete results relevant to one case community.

    The community of nutrition and dietetics professionals was chosen as the case community given its history of engagement with SFS, its integration throughout food system sectors, and because dietary shifts have significant potential to contribute to SFS. Furthermore, the researcher’s position as a member of this community supported the case study work.

    The research uses transdisciplinary methods guided by the Framework for Strategic Sustainable Development (FSSD) and Community Development theory. The FSSD provides a concrete definition of sustainability and includes methodological supports for co-creation of sustainability transitions. Community Development theory supports participatory approaches and welcomes different knowledge cultures in such co-creation. The Delphi Inquiry method was used to facilitate data collection and community engagement. For measurement-specific elements of the research, causal loop diagrams (CLD) informed by the Cultural Adaptation Template (CAT) theory were used, and Critical Dietetics was used as a framework for dietetics-specific analysis.

    High level insights include that: (i) participatory and multidimensional approaches are important to facilitate community engagement in SFS development; (ii) objective parametres for defining sustainability are critical to guide concerted action and can provide an innovation space that invites creative and diverse solutions within; (iii) systems thinking and related tools help simplify the complexity of food systems without disregarding broader context, and support assessment in the absence of all data. Specifically in relation to the case community explored, insights include that, (i) integrating an SFS lens into existing roles and activities is important, because dietitians already work across sectors and scales, making them well positioned to contribute in diverse ways; (ii) a shared language based on transdisciplinary understandings of SFS is required; (iii) engaging in activities that facilitate SFS knowledge development within the profession, prior to integrating it into roles and activities, is an important first step; (iv) collaborative and reflexive approaches to continued knowledge development and practice are important, such that in the end sustainability becomes integrated into a cultural way of thinking about food.  

    Based on these insights, this dissertation outlines a procedure for collaborative community work for globally SFS. The procedure is adaptable to various community settings. The dissertation also provides specific guidance for how dietitians could utilise their strategic positions throughout food systems to contribute to SFS development.

    Sheet metal forming in the era of industry 4.0: using data and simulations to improve understanding, predictability and performance2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    A major issue within automotive Sheet Metal Forming (SMF) concerns ensuring desired output product quality and consistent process performance. This is fueled by complex physical phenomena, process fluctuations and complicated parameter correlations governing the dynamics of the production processes. The aim of the thesis is to provide a deeper understanding of the challenges and opportunities in this regard within automotive SMF. The research is conducted in collaboration with a global automotive manufacturer. 

    The research shows that systematic investigations using process simulation models allow exploration of the product-process parameter interdependencies and their influence on the output product quality. Furthermore, it is shown that incorporating in-line measured data within process simulation models enhance model prediction accuracy. In this regard, automating the data processing and model configuration tasks reduces the overall modelling effort.

    However, utilization of results from process simulations within a production line requires real-time computational performance. The research hence proposes the use of reduced process models derived from process simulations in combination with production data, i.e. a hybrid data- and model-based approach. Such a hybrid approach would benefit process performance by capturing the deviations present in the real process while also incorporating the enhanced process knowledge derived from process simulations. Bringing monitoring and control realms within the production process to interact synergistically would facilitate the realization of such a hybrid approach.

    The thesis presents a procedure for exploring the causal relationship between the product-process parameters and their influence on output product quality in addition to proposing an automated approach to process and configure in-line measured data for incorporation within process simulations. Furthermore, a framework for enhancing output product quality within automotive SMF is proposed. Based on the thesis findings, it can be concluded that in-line measured data combined with process simulations hold the potential to unveil the convoluted interplay of process parameters on the output product quality parameters.

    Bridging Theory and Practice in Media Technology2019Report (Other (popular science, discussion, etc.))
    Abstract [en]

    In a course focusing on visual storytelling, students explore the course content through an inquiry-pro-cess that consists of creating digital productions (such as short movies and animations) and writing a scientific text discussing the process. The balancing act between practice and theory has presented some challenges when designing a course that should both provide an aesthetic & technological founda-tion for further courses as well as encouraging students to explore the course content by undertaking inquiries and writing their own research questions. An issue of the first iteration of the course was also lack of alignment between examination activity (seminar) and course activities (projects & presentations).

    Abstract [en]

    Training engineering graduates in sustainable development literacy is an urgent task for aca-demic institutions. Even though environmental and social considerations are critical dimen-sions to be leveraged when designing quality advanced design-implement (D-I) experiences for students, sustainability is often confined to environmental protection and suffers from the under-development of the social dimemsion.

    “Thinking by doing”: making as a vital part of engineering education2019Report (Other (popular science, discussion, etc.))
    Abstract [en]

    The engineer of the 21st century is expected to possess a broad range of skills and abilities. Besides more traditional technical knowledge and engineering skills, interpersonal skills, critical thinking, creativity and design makes its way into the curriculum of our engineering education. At the department of me-chanical engineering, the underlying pedagogical approach to teaching engineer-ing design is based on constructivism. Research has shown that a very good way for students to “construct” their knowledge is to design, build and publicly share artifacts. Consequently, we are aiming to make design and prototyping an integral part of our engineering education. This align well with the CDIO initiative of which BTH is part since 2013.

    Ett politiskt bygge: - översiktsplaneringens innehållsmässiga utveckling2020Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Debate often describes the evolution of spatial planning as a process of neo-liberalisation. However, this evolution has not been studied from the perspective of planning in general in Sweden. Whether comprehensive planning is also undergoing neo-liberalisation is considered here based on these overarching research questions: 

    -          To what extent has spatial planning undergone neo-liberalisation?

    -          How can the evolution of comprehensive planning be understood as a neo-liberalisation process?

    Answering these questions requires an understanding of the content characterising this planning, and of what a neo-liberalisation process entails. To achieve such an understanding, this dissertation examines how planning in general can be understood as both a political control system and a market-based land use regime.

    The discourse of comprehensive planning was studied by analysing 17 comprehensive plans adopted in five municipalities over the 1989–2014 period.

    Generally, these plans follow a few main evolutionary paths. Municipal comprehensive planning has transitioned from being instrumental, encountering few problems, to becoming increasingly abstract and all-encompassing. Comprehensive planning increasingly concerns how growth is to be achieved locally. This change is occurring in both form and content. Change in form refers to the fact that comprehensive planning has been encompassing more and more subject areas over time, whereas change in content refers to the increasingly market-based content of such planning.

    The research question regarding the extent to which spatial planning is undergoing neo-liberalisation is answered by the obvious trend towards neo-liberalisation. This trend is not pervasive, as countervailing tendencies are also present. Spatial planning is thus becoming internally contradictory, with earlier values persisting, albeit often in interaction with new ones.

    The question of how comprehensive planning can be understood as a neo-liberalisation process has a three-part answer:

    -          As content in comprehensive plans, neo-liberalisation can be understood as a focus on market rationality. 

    -          As form in comprehensive plans, neo-liberalisation can be understood as policy production with content that assumes an ever more neo-liberal orientation. Comprehensive planning during the studied period has come to include more and more municipal areas of activity.

    -          From a neo-liberal perspective, neo-liberalisation is understood as economic utility maximisation.

    Planning is becoming increasingly neo-liberalised, but not neo-liberal. That this has occurred as a result of increasingly comprehensive policy formulations is somewhat surprising. We are faced with the politicisation of planning in general, which is increasingly informed by market-based policy. This trend represents a comprehensive policy shift towards more neo-liberal planning content, accompanied by more policies. More principles are appearing, addressing how planning and development are to proceed compared with the content of pre-existing plans. The neo-liberalisation process is thus occurring via means that are contradictory from a neo-liberal perspective.

    Improvements of students learning through changes in feedback and examinations in introduction to strategic sustainable development 7,5 credits2018In: Lärarlärdom 2018 / [ed] Claes Dahlqvist, Kristianstad, 2018, p. 26-38Conference paper (Refereed)
    Abstract [en]

    Each year at the Blekinge Institute of Technology, in total 15-30 international master students from the Structural Dynamics and the Erasmus program take a 7.5 credit course in strategic sustainable development. In 2016, the course had rather good scoresfrom the students’ course evaluation, but the students also identified a need for improvements regarding feedback from teachers during the course and also regarding the examination of the course. A study was therefore initiated, aimed at finding out if changes in feedback and examinations can increase students’ learning towards the learning outcomes in the course, and if so, how the teaching and examination in the course could be developed in such direction. The study found through literature review, interviews among colleagues, and surveys among students that instead of a final exam, several knowledge tests and reflective questions during the course could increase the students’ learning. The course design was developed and then implemented in 2017. According to the students’ course evaluation the same year, this lead to even better perceived learning. Except from providing further evidence that students’ learning increases with individual feedback, the study showed how that can be implemented.

    A Step Towards the Design of Collaborative Autonomous Machines: A Study on Construction and Mining Equipment2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Fully autonomous construction and mining machines are not science fiction anymore. For special applications, these types of machinery are well known for several years. The construction and mining industries are ripe for innovative product and service offers, including automated and fully autonomous machines at a larger scale. Nevertheless, commercially available autonomous machines for the main markets are still rare. Driven by the advancements in sensor technology, increased connectivity, and on-board computational capabilities, automation of machine functions and subsystems led to the development of advanced operator-assistant functions in certain fields like material handling, predictive maintenance, and operator guidance. Semi-automated machines, supporting the machine operator during normal operation, are well accepted by users and customers and show beneficial effects on the productivity of the machine and the overall work process. The purpose of this thesis is to generate a deeper understanding of the specific requirements needed to support the design decisions during the development of fully autonomous machines. Complementary, deeper insights into the efficient collaboration between autonomous machines and human collaborators are explored.

    The thesis summarizes the research performed by the author, as an industrial Ph.D. student and Specialist for Intelligent Machines at Volvo Construction Equipment. Performed research comprises the investigation of the state-of-the-art approaches in the automation of machines and dedicated functions with special emphasis on the connectivity of the different systems and components up to the site management solution. Further, the work includes the exploration of data-mining through early experience prototyping as a step towards data-driven design of a product-service system. In additional the research covered the support of on-site collaboration between autonomous machines and humans by investigating team behavior and trust development among humans.

    Conclusions from this work are that autonomous machine design requires new sets of requirements to support early decision making during the development process. Dedicated data collection based on different methods such as, data-mining, needfinding, and observations, supported by multiple physical and virtual artifacts can generate useful data to support the decision-making. Trust between humans and machines, and the preconditions of developing this trust need to be captured as specific requirements. To support further development in the area of autonomous machine design, an interaction model had been proposed to map possible interactions of an autonomous machine with objects and collaborators within the same work area. To capture the different nature of the possible interactions, several levels had been introduced to enable the distinction between cognitive, and physical, as well as intended, and unintended interactions.

    Interactive animation of single-layer cumulus clouds using cloudmap2019In: Eurographics Proceedings STAG: Smart Tools and Applications in Graphics (2019) / [ed] M. Agus, M. Corsini and R. Pintus, Eurographics - European Association for Computer Graphics, 2019Conference paper (Refereed)
    Abstract [en]

    In this paper, we present a physics-driven procedural method for the interactive animation of realistic, single-layered cumulus clouds for the landscape-scale size. Our method employs the coarse units called parcels for the physics simulation and achieves procedural micro-level volumetric amplification based on the macro physics parameters. However, contrary to the previous methods which achieve amplification directly inside the parcels, we make use of the two-dimensional texture called cloud mapsto this end. This not only improves the shape and distribution of the cloud cover over the landscape but also boosts the animation efficiency significantly, allowing the overall approach to run at high frame rates, which is verified by the experiments presented in the paper.

    Parents' experiences of a health dialogue in the child health services: a qualitative study2019In: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 19, no 1, p. 774-Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The Child Health Services in Sweden is a well-attended health promoting setting, and thereby has an important role in promoting healthy living habits in families with young children. Due to lack of national recommendations for health dialogues, a Child Centred Health Dialogue (CCHD) model was developed and tested in two Swedish municipalities. The aim of this study was to explore parents' experiences of health dialogues based on the CCHD model focusing on food and eating habits during the scheduled child health visit at four years of age. METHODS: A qualitative design with purposeful sampling was used. Twelve individual interviews with parents were conducted and analysed with qualitative content analysis. RESULTS: The analysis resulted in three categories: The health dialogue provides guidance and understanding; Illustrations promote the health dialogue; and Space for children and parents in the health dialogue. In addition, analysis of the latent content resulted in a single theme reflecting the parents' voice on the importance of having a health dialogue on food and eating habits. The health dialogue, promoted by illustrations, provided guidance and understanding, and gave space for children's and parents' involvement. CONCLUSIONS: The results indicate that health dialogues using the CCHD- model create supportive conditions for family members' active participation in the visits, which may strengthen empowerment and health literacy. The study provides knowledge and guidance for further development, evaluation and implementation of the model.
