    Malignant Melanoma Classification with Deep Learning2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Malignant melanoma is the deadliest form of skin cancer. If correctly diagnosed in time, the expected five-year survival rate can increase up to 97 %. Therefore, exploring various methods for early detection can contribute with tools which can be used to improve detection of disease and finally to make sure that help is given in time.

    The purpose of this work was to investigate the performance and behavior of different convolutional neural network (CNN) architectures and to explore whether presegmenting clinical images would improve the prediction results on a binary classifier system.

    For the purposes of this paper, the two selected CNNs were Inception v3 and DenseNet201. The networks were pretrained on ImageNet and transfer learning techniques such as feature extraction and fine-tuning were used to extract the features of the training set. Batch size was varied and five-fold cross-validation was applied during training to find the optimal number of epochs for training. Evaluation was done on the ISIC test set, the PH2 dataset and a combined set of images from Karolinska University Hospital and FirstDerm, where the latter was also cropped to evaluate presegmentation.

    The achieved results for the ISIC test set were AUCs of 0.66 for Inception v3 and 0.71 for DenseNet201. For the PH2 test set, the AUCs were 0.82 and 0.73. The results for the Karolinska and FirstDerm set were 0.49 and 0.42. Presegmenting the latter test set resulted in AUCs of 0.58 and 0.51.

    In conclusion, quality of images could have a big impact on the classification performance. Batch size seems to affect the performance and could thus be an important hyperparameter to tune. Ultimately, the Inception v3 architecture seems to be less affected by different variability why selecting this architecture for a real-world clinical image application could be more suitable. However, the networks performed much worse than state of the art results in previous papers and the conclusions are based on rather inconclusive results. Therefore more research has to be done to verify the conclusions.

    Adaptable Semi-Automated 3D Segmentation Using Deep Learning with Spatial Slice Propagation2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Even with the recent advances of deep learning pushing the field of medical image analysis further than ever before, progress is still slow due to limited availability of annotated data. There are multiple reasons for this, but perhaps the most prominent one is the amount of time manual annotation of medical images takes. In this project a semi-automated algorithm is proposed, approaching the segmentation problem in a slice by slice manner utilising the prediction of a previous slice as a prior for the next. This both allows the algorithm to segment entirely new cases and gives the user the ability to correct faulty slices, propagating the correction throughout. Results on par with current state of the art is achieved within the domain of the training data. In addition to this, cases outside of the training domain can also be segmented with some accuracy, paving the way for further improvement. The strategy for training the network to utilise auxiliary input lies in the heavy online data augmentation, forcing the network to rely on the provided prior.

    A System of Systems of Mental Health in Cities: Digging Deep into the Origins of Complexity2019In: Article in journal (Refereed)
    Abstract [en]

    Mental health in urban environments is often treated from a healthcare provision perspective. Research in recent decades showed that mental illness in cities is a result of dysfunctional coordination between different city systems and structures. Given the nature of the city as a system of systems, this work builds participatorily a general system dynamic model of factors that affect mental health in urban and regional environments. Through this method, we investigated the challenges of the application of such methodology to identify important factors, feedback loops, and dependencies between systems to move forward in planning for mental health in cities. The outcome is a general model that showed the importance of factors that vary from individuals, families to communities and feedback loops that span multiple systems such as the city physical infrastructures, social environments, schools, labor market, and healthcare provision.

    In Search of Lost Deterrence – Two essays on deterrence and the models employed to study the phenomenon2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    To deter is central for strategic thinking. Some of the more astute observations regarding the dynamics of deterrence were made during the Cold War by game theorists. This set the stage for how deterrence has come to be studied. A strong methodological element like the research on deterrence’s reliance on game theory requires examination in order to understand what sort of knowledge it actually yields. What sort of knowledge does one acquire when deterrence is viewed through game theoretic models? How do they inform us about the phenomenon of deterrence? To understand the nature of a phenomenon through models requires idealization, which in turn presupposes assumptions. This licentiate thesis investigates the type of knowledge we attain when approaching deterrence from a game theoretic perspective. The two articles presented address two separate but related issues. The first article reviews a debate regarding which deterrence model best capture the phenomena of deterrence, i.e. how models can be compared to one and other. The article presents a framework for comparing models and then appraises how these different deterrence models inform us about deterrence. The second article uses one of the more central deterrence models in order to evaluate how and to what extent the naval operation Atalanta managed to deter the Somali piracy.

    Gaming Simulation Validation: Matching Participants’ Worldviews with Their Decisions2019In: ISAGA 2018, 2019Conference paper (Refereed)
    Abstract [en]

    Gaming simulation is a successful approach to many issues where a holistic view is important. However, to use results from gaming simulations, the game has to be validated. This paper proposes a two-step approach for process validation of behavior for the gaming simulation by comparing decisions that players make in a game with the perceptions that affect their real-life decisions. Two case studies, where this approach was applied, are presented and the results are analyzed and discussed. A strong correlation between behavior during the games and in the real world was observed. This correlation indicates that gaming simulations in these cases are validated and represent the real system in an accu-rate manner. Thus, these cases show that the proposed approach works and can be used for validation of gaming simulations.

    Gamifying Project Procurement to Incorporate Better Goals of Organizations in the Public Sector: A participatory simulation approach on a Swedish road construction use case2019In: Operations Research PerspectivesArticle in journal (Refereed)
    Abstract [en]

    Governmental institutions need to ensure work of infrastructures, and in most cases, it is done using project procurement process. Such processes have highly complex and dynamic interaction. It leads to issues, such as information asymmetry, over-specified tenders, not efficient feedback loops, etc. As result, projects can rarely match objectives of organizations. This paper explores the use of participatory simulation to help holistically investigate a project procurement process. Based on case studies from the Swedish road construction field, it can be concluded, that a participatory simulation is an effective approach to experiment with the effects of project procurement.

    Energi som fysikbegrepp och samhällsfråga: En jämförande innehållsanalys av gymnasieläroböcker2019Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    According to the Swedish curriculum for the senior secondary school from 2011, it is part of the physics subject that students should be able to participate in debates about social issues and to discuss ethical issues from a scientific perspective. Sustainable development can contribute to an understanding of the importance of physics in the society, with the energy concept, energy resources and energy usage for a sustainable society included in the course Physics 1. How this is manifested can be analyzed in terms of scientific literacy, emphases, socio-scientific issues, etc. The study compares four textbooks for Physics 1 using a quantitative, but interpreting, text analysis based on a method and coding scheme developed by Engström for investigating how sustainable energy systems is dealt with in education and textbooks for Physics A according to the Swedish curriculum for the upper secondary school from 1994. A comparison is also made between textbooks for Physics 1 and Science studies 1b concerning the energy area in order to compare differences in emphasis between different visions of scientific literacy for the two subjects. Furthermore a qualitative text analysis is made between different editions of the same textbook series about to what extent the divergence can be explained by the difference in curricula. Finally a qualitative text analysis is included about how concepts related to the second law of thermodynamics is dealt with in the textbooks and to what extent this corresponds with other differences. The content analysis indicates that the difference between the textbooks in physics concerning visions of scientific literacy is comparatively small, but larger when it comes to contents related to technical applications. On the other hand, the difference is obvious between the subjects, with the textbooks in physics being dominated by vision I, which is dominated by science as such and its methods, while the textbooks in science studies have a decidedly larger element of vision II, thus including more attempts to set science in its social and political context. The difference in how the textbooks in Physics describe the second law of thermodynamics is in accordance with the quantitative text analysis. To what extent the debate between different views of scientific literacy in Sweden is handled by having separate subjects with partly overlapping contents is discussed. Likewise whether there is a tendency that the formulation in the curriculum conserves the choice of which socio-scientific issue is brought up in the teaching. This would, however, be in conflict with the principle that these should be current and of interest to the students.

    A Light Booster metro car for the commuting work force: Human Centric Lighting in underground transportation2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    People at northern latitudes lack an effective portion of daylight, especially in winter time, to entrain their circadian rhythm. If one belongs to the group of employees who have no time for daylight exposure and are not supplied by Human Centric Lighting (HCL) in their office, the only chance to get circadian light may be the daily commute. The mega trend of urbanisation increases time of commute, with on average 20-60 minutes spent daily in public transportation in European cities. By introducing HCL to public transport, especially metro vehicles, this time frame can be used to provide the commuting work force with circadian lighting. A LIGHT BOOSTER metro car is proposed to provide the right intensity, spectral distribution, directionality and timing of light to regulate the human inner clock and support health. The LIGHT BOOSTER metro car is very efficient as light is best used due to a high person per square meter ratio. This ratio is higher than in any office building. The energy consumption equals that of an conventional single household. Besides expected health benefits, the LIGHT BOOSTER metro car works as an educative tool, raising awareness for the beneficial effects of light on human health and well-being.

    Development of Risk Oriented Accident Analysis Methodology for Assessment of Effectiveness of Severe Accident Management Strategy in Nordic BWR2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Nordic Boiling Water Reactor (BWR) design employs ex-vessel debris coolability as a severe accident management strategy (SAM). In case of a severe accident, the debris ejected from the vessel are expected to fragment, quench and form a debris bed, which is coolable by a natural circulation of water. Success of the existing SAM strategy depends on melt release conditions from the vessel which determine (i) properties of ejected debris and, thus, ex-vessel debris bed coolability, and (ii) potential for energetic melt-coolant interactions (steam explosion). The strategy involves complex interactions between physical phenomena (deterministic) and transient accident scenarios (probabilistic).The aim of this work is further extension, implementation and application of the Risk-Oriented Accident Analysis Methodology (ROAAM) to assessment of the severe accident management strategy effectiveness. ROAAM was originally developed for rare, high-consequence hazards, where both aleatory (stochastic) and epistemic (modeling) uncertainties play a significant role in the risk assessment. The main purpose of ROAAM is to provide the input material to an underlying decision making regarding current safety design acceptance, procedures and possible design modifications.This work reports results of (i) development and implementation of probabilistic framework (ROAAM+) for streamlining sensitivity analysis, uncertainty quantification and risk analysis; (ii) analysis of in-vessel phase of accident progression and melt release conditions in Nordic BWR reactor design with MELCOR code; (iii) analysis of the effect of melt release conditions predicted by MELCOR code on the risk of ex-vessel steam explosion.In ROAAM+, “full models”, such as MELCOR code, are used to develop computationally efficient “surrogate models” to enable extensive uncertainty quantification and failure domain analysis. ROAAM+ analysis identified specific assumptions in MELCOR models, which are currently the major contributors to the uncertainty in the assessment of the SAM effectiveness.

    Energioptimering av destillationsprocess med ejektorteknik2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a report that aims to map qualified suppliers to Aqua‐Nova. The company's organization is small and consists of five employees. It is therefore a challenge to sell new projects, monitor production and care for customer relations and at the same time conduct development projects. The work is based on a technical report obtained by Aqua‐Nova. The report investigates a possible optimization of the distillation process using ejector technology.

    The purpose of this thesis was to investigate the most suitable subcontractor of ejectors for Aqua‐Nova. The purpose was to also answer the four detailed objectives.

    • What advantages and disadvantages are created by introducing an ejector into the system?
    • What customer benefits does an ejector provide?
    • What requirements are placed on the technology to work together with Aqua‐Nova's current system?
    • What requirements are placed on suppliers in terms of competence, delivery ability and price?

    Through Google searches, examination of Achema industrial fair and through interviews, eleven suppliers were found who met the requirements specification. With Pugh and Kesselring matrices, a two‐step screening process was performed. The British company Transvac Systems Ltd. got the highest score in both screenings and is thus considered the most suitable supplier. 

    The screening process was supplemented by a competition analysis, a risk analysis and an interview to answer the detailed objectives. The competition analysis aims to investigate the pros and cons of the development project and shows that Aqua‐Nova can increase its market share by differentiating the product. The focus should be on the markets where cooling water is a scarce commodity and the companies that suffer from space shortages. The customer benefits become a more environmentally friendly and profitable product. The risk analysis shows whether there is a risk of implementing new technology in Aqua‐Nova's system. Based on the result, the risk of the ejector causing a downtime is minimal. The interview shows that a supplier must be able to deliver tailor‐made ejectors and how the ejector should be designed to work in the Aqua‐Nova system.

    The result can be considered credible since the screening process was performed in two steps. The risk and competition analysis give a representation of the challenges the company can face with the development project.

    The result ought to be supplemented by a cost analysis and developing of a test facility to ensure profitability and a functional product.

    Geometric Control of Thrust Propelled Systems2019Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This thesis was motivated and inspired by the AEROWORKS project, a European research project, whose main goal was to deploy multiple heterogeneous unmanned aerial vehicles in environments where human intervention is restricted.In particular, this thesis focuses on control of aerial vehicles for the purposes of cargo transportation, an application of interest, for example, in inspection and maintenance of aging infrastructures.

    This thesis also focuses on control of multi-agent systems, where agents are required to accomplish some common goal, such as collaborating on transporting a common cargo. In the first part of this thesis, we focus on control of thrust-propelled systems.A thrust-propelled system is similar to a multi-rotor system, where a thrust input is available along some direction, which we can rotate by means of a torque input.In a first step, we develop controllers for the thrust-propelled system, by application of nonlinear control techniques.In a second and final step, we convert a physical system, by means of an appropriate change of coordinates, into the thrust-propelled system form, at which point we are able to leverage the controllers designed in the first step.Among the physical systems considered in this thesis, we highlight slung-load transportation, where a point-mass cargo is tethered to a single aerial vehicle, and slung-bar transportation, where a bar cargo is tethered to two aerial vehicles.Another key idea, exploited throughout this thesis, is that of geometric control, where one attempts to design controllers that are independent of the user choices.For example, when performing an experiment, a user picks a reference frame, and the application of a geometric controller is insensitive to that choice.On the contrary, a non-geometric controller yields different results depending on which frame is chosen.Experiments and simulations illustrate the performance of the proposed control strategies.

    In the second part of this thesis, we focus on global stabilization of mechanical systems, in contrast with the first part, where almost global and/or local stabilization sufficed.However, for non-contractible sets, which are pervasive throughout this thesis, a globally asymptotically stable equilibrium point does not exist under a continuous control law.In particular, we consider a rigid-body pendulum, which we wish to globally stabilize at some desired configuration.To accomplish the latter, we create a graph between several stabilizing continuous control laws, and switch among them so as to provide the desired equilibrium with a global region of attraction, which we validate in simulations.

    In the final part of this thesis, we consider a multi-agent system composed of rotation matrices, and we design controllers that guarantee asymptotic incomplete synchronization.In particular, we develop decentralized torque controllers for the agents, and when the directions to be synchronized are principal axes, we are able to propose torque control laws that do not require torque input in all bodies directions, but rather only in the body directions orthogonal to the respective principal axis.Simulations are then presented which illustrate the performance of the proposed control strategy.

    Macroeconomic factors in Probability of Default: A study applied to a Swedish credit portfolio2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Macroeconomic conditions can impact the payment capacity of individual mortgage holders' household loans. If the clients of a bank's retail credit portfolio experience deteriorating paymentcapacity it will reflect on the probability of default of the overall portfolio. With IFRS 9, banks are expected to sophisticate their calculations of expected credit loss, demanding forward-looking estimates of probability of default by incorporation of macroeconomic forecasts. Finding what macroeconomic factors have a statistical significant relationship to the actual default frequency of a portfolio can aid banks in estimating probability of default with reference to current and forecasted macroeconomic conditions.

    This study aims to explore the relationship between macroeconomic factors and the default frequency in a Swedish retail credit portfolio. The research is based on quantitative data analysis of historical default data, complemented by implications of the macroeconomic condition on the payment capacity of households from a theoretical perspective.

    Macroeconomic factors studied are the Swedish gross domestic product, house price index, reporate and unemployment rate. The supporting data consists of default data from Nordea's Swedishretail credit portfolio. The time period covers 2008-2015 and provides basis for analysis of a timeperiod with different conditions in the macroeconomy, including effects of the 2008 financial crisis. A multiple linear regression model is used as a method to suggest the relationship between themacroeconomic factors and the default frequency. The model coefficients are estimated with calculations of Ordinary Least Squares and the significance supported by statistical test.

    Results show that gross domestic product and repo rate are statistically significant macroeconomic variables in explaining changes in the default frequency and thus probability of default of a Swedish retail credit portfolio.

    Opportunities to Optimize the Palm Oil Supply Chain in Sumatra, Indonesia2019In: Energies, ISSN 1996-1073, E-ISSN 1996-1073, Vol. 12, no 420Article in journal (Refereed)
    Abstract [en]

    Significant amounts of biomass residues were generated in Indonesia. While untreated, residues emit greenhouse gases during the decomposition process. On the other hand, if efficiently utilized, these residues could be used to produce value-added products. This study investigates opportunities for harnessing the full potential of palm oil residues (i.e., empty fruit bunches, kernel shells, fiber, and mill effluent). As far as we are aware, the study is the first attempt to model the palm oil supply chain in a geographically explicit way while considering regional infrastructures in Sumatra Island, Indonesia. The BeWhere model, a mixed integer linear programming model for energy system optimization, was used to assess the costs and benefits of optimizing the regional palm oil supply chain. Different scenarios were investigated, considering current policies and new practices leading to improved yields in small-scale plantations and power grid connectivity. The study shows that a more efficient palm oil supply chain can pave the way for the country to meet up to 50% of its national bioenergy targets by 2025, and emission reductions of up to 40 MtCO2eq/year. As much as 50% of the electricity demand in Sumatra could be met if residues are efficiently used and grid connections are available. We recommend that system improvements be done in stages. In the short to medium term, improving the smallholder plantation yield is the most optimal way to maximize regional economic gains from the palm oil industry. In the medium to long term, improving electricity grid connection to palm oil mills could bring higher economic value as excess electricity is commercialized.

    Development of novel molecular and microfluidics tools for identification and characterization of latent HIV-1 reservoir2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The existence of latent HIV-1 reservoir (LR) in all HIV-1 infected patients serves as a major obstacle to completely cure HIV-1 infection. However, up to now there is still no available assay that provides an accurate measurement of the reservoir size. This thesis aims to address this challenge from different aspects with several novel technologies, using both molecular and microfluidics-based tools. To find a proper tool to identify the latent HIV-1 reservoir, in Paper I and II, LIPS assay, RNAflow, and RNAscope assay were optimized and evaluated for indirect and direct detection of latent HIV-1 reservoir. The results indicated the LIPS method might not be sufficient for latent HIV-1 reservoir detection, although it has been proposed to quantify the latent HIV-1 reservoir indirectly. Furthermore, the optimized RNAscope technique performed better than RNAflow for transcription and translation competent latent HIV-1 reservoir identification. The RNAscope was also found to be independent of the HIV-1 subtype and can be applied to patient samples at single cell level. As there are currently no available surface biomarkers for latent HIV-1 reservoir, in Paper III, transcriptomics and proteomics-based analysis method for high-throughput selection of potential biomarker were established and applied to different patient groups. Twelve membrane protein-coding genes were identified as downregulated in the patient group who were hypothesized to have lower latent reservoir. These proteins might have the potential to be used as surface biomarkers for latent HIV-1 reservoir. CD4+ T cells, monocyte/macrophages, and natural killer cells are believed to be the primary source for HIV-1 reservoirs in peripheral blood. In paper IV, a microfluidic chip was developed to simultaneously isolate these three mononuclear leukocyte cell types directly from whole blood. The microfluidic method reduces the sample volume requirement and is a promising tool for latent HIV-1 reservoir study. Together, though further improvement and clinical verification are necessary, the work in this thesis has contributed to the advancement of latent HIV-1 reservoir characterization and may facilitate future development of the latent HIV-1 reservoir targeting and clearance methods with the ultimate goal – to cure HIV-1 infection.

    Livsberättelser åskådliggör minnen om erfarenheter av och uppfattningar om matematik2019Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to find out how students´ memories about their experiences of mathematics teaching influence their perception of mathematics as subject and mathematics teaching, and if these perceptions can be connected to the chosen learning theories: a socio-cultural, a cognitive and a behavioral learning theory. Another aim of this report is to describe positive and negative positions in relation to the mathematics as subject and mathematics teaching based on students' stories about mathematics teaching.

    The research issues for this study are:

    - How have students´ memories of their experiences contributed to their current perceptions of mathematics as subject?

    - How can students´ memories of their experiences in mathematics be explained according to selected learning theories?

    To obtain empirical data within the study, five individual interviews were conducted with students in 8th grade in a school outside Stockholm. The result is presented in different profiles for the students projected as life stories. The result shows that negative perceptions about the subject were often based on the fact that they did not understand how a task would be solved, and they therefore got stuck. Those who experienced the subject of mathematics negatively experienced that it was That it is easier to compare results and knowledge within mathematics than other subjects, as there often are only one correct answer. The result also shows that the main reason why the students developed a positive opinion in relation to the subject is that they have lived with the feeling that they are able to solve tasks without problems.

    The result also shows that the themes that could be distinguished life stories told by the students were relatable and able to interpret through more than one learning theory. Which may indicate that different theories can explain a good learning and how positive emotions develop to a topic and explain when there is not enough learning which can create knowledge gaps and the development of negative emotions on the subject.

    Social cohesion in Gilbert Hill: What can be done to better integrate the informalitywithin the formal planning process2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The government in Maharashtra are trying to rehabilitate the informal settlements in Mumbai

    through the slum rehabilitation authority and its rehabilitation scheme and we wanted to learn

    more about how it worked and how it affects living conditions for former residents of an

    informal settlement and how it can differ from those still living there.

    This study has a focus on a specific informal settlement in Mumbai, called Gilbert Hill.

    Through observations and interviews with people living in the area, the research investigates

    resident’s opinions and experiences. Interviews with officials, involved in the planning of

    Mumbai were conducted, in order to learn how the interaction between formal and informal

    structures looks like. The results will be presented in this report and will give an insight of the

    life in an informal settlement in Mumbai as well as the thoughts and efforts with the

    rehabilitation of said settings.

    Our findings have been analysed and discussed in the light of David Harvey’s The right to

    city, displacement theories, theories about the public private partnership and what it is that

    makes informal settlements to persist.

    We have discovered that it is not as easy as to just redevelop an informal settlement according

    to a uniform plan. Residents have special bonds to the neighbourhood, both between each

    other and to the place itself. Even though the residents might be viewed as impoverished and

    underprivileged they still should have a right to form their future as well as their

    surroundings. They certainly have a will to do so.

    OPEN DATA AND INNOVATION ADOPTION: Lessons From Sweden2018Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The Internet has significantly reduced the cost of producing, accessing, and using data, with governments, companies, open data advocates, and researchers observing open data’s potential for promoting democratic and innovative solutions and with open data’s global market size estimated at billions of dollars in the European Union alone (Carrara, Chan, Fischer, & Steenbergen, 2015). This thesis explores the concept of open data, describing and analyzing how open data adoption occurs to better identify and understand key challenges in this process and thus contribute to better use of the available data resources and valuable services for citizens.This research explores the overarching research problem: How does the process of open data adoption occur? Specific research questions include: RQ1: What is the state of open data in terms of political, social, and economic perspectives? RQ2: Who are the main stakeholders utilizing open data; what is their position in the ecosystem, and how do they collaborate? RQ3: Which issues influence open data adoption for open data projects and how? RQ4: What are the potential determinants of open data adoption for open data-driven innovation, and how do these factors influence adoption? To answer these questions, this research has followed an inductive research approach followed by a deductive approach, using both quantitative and qualitative methods.First, this thesis involves macro-level analysis of an open data platform. Second, the thesis maps the open data ecosystem and identifies the ecosystem’s key actors. Third, it determines organizations’ issues and challenges while working with open data and, finally, empirically verifies the factors influencing open data adoption at the organizational level. This research has successfully identified three factors influencing open data adoption—organizational readiness, perceived effort, and perceived benefits—and three that do not (perceived usefulness, perceived risk, and external pressure). Organizational readiness was found to have the greatest influence on open data adoption.The thesis is organized in a hybrid format, meaning it is a monograph with a compilation of studies. The dissertation is structured as follows: First, the introduction defines the open data concept and innovation adoption and explains the reason for this dissertation. Second, the thesis provides an analysis of relevant previous studies, theories, concepts, models, frameworks, and methods. Third, a detailed explanation is given on the methodologies used. Fourth, the empiricalivportion of this thesis comprises four individual studies that constitute the empirical foundations of the research problem. Each study analyzes one research question using its own methodological approach. Fifth, answers to research questions and limitations of this thesis, as well as future research implications, are presented. The conclusion section summarizes this dissertation and its contributions to the areas of open data and innovation adoption.

    On Gas Contaminants, and Bipolar Plates in Proton Exchange Membrane Fuel Cells2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The proton exchange membrane (PEM) fuel cell is an electrochemical device that converts chemical energy into electrical energy through two electrocatalytic reactions. The most common catalyst used is platinum on carbon (Pt/C), which has shown the best performance in the fuel cell until now. However, the drawback of this catalyst is that it does not tolerate impurities, and both hydrogen and oxygen may carry small amounts of impurities depending on the production sources. The purpose of this thesis is to understand the effect of two impurities that are less investigated, i.e., ammonia, which may accompany the hydrogen rich reformates from renewable sources, and nitrogen dioxide, which may come from air pollution. The mechanism of contamination and an adequate recovery method for the respective contaminant are studied. Additionally, electroplated bipolar plates with Ni-Mo and Ni-Mo-P coatings were tested as alternatives to stainless steel and carbon materials.

    The results show that ammonia not only provokes changes in the polymer membrane but also in the oxygen reduction reaction (ORR), hydrogen oxidation reaction (HOR) and catalyst ionomer in both electrodes. The extent of performance recovery after the contamination depends on the concentration used and the exposure time. In contrast, nitrogen dioxide affects the catalyst in the electrode directly; the contamination is related to side reactions that are produced on the catalyst’s surface. However, NO2 is not attached strongly to the catalyst and it is possible to restore the performance by using clean air. The time the recovery process takes depends on the potential applied and the air flow.

    Finally, the evaluation of electroplated Ni-Mo and Ni-Mo-P on stainless steel by ex situ and in situ studies shows that these coatings reduce the internal contact resistance (ICR) and the corrosion rate of the stainless steel considerably. However, the in situ experiments show that phosphorus addition to the coating does not improve the fuel cell performance; thus, the Ni-Mo alloy is found to be a promising choice for electroplating stainless steel bipolar plates.

    Abstract [en]

    Between Bredäng, Fruängen and Mälarhöjden is a small woodland situated. It is mountainous and full of thicket. The distant noise from the E20 interacts with the sounds of birds and the leaves rustling in the wind. It is a midpoint between different types of residential buildings built over decades, a breakpoint between city and nature.

    In the woodland there is a small site that will accommodate a new school that gather the different areas. With a grid and simple geometric shapes, both internal and external spaces are created with different character and function. Long and bright corridors are given a clear movement in the building with entrances from several directions. One part of the grid is disengaged from the school building and consists of six yards. These yards are characterized by different natural elements, such as water, greenery and stone coatings. An atrium yard has a pond that reflects the sky and makes it present even in the middle of the school. The remaining yards have different functions that can be used both in the education and in the breaks. Outside the library, for example, there is a book yard and outside the woodwork there is a stone carved carpentry yard.

    The school’s design is based on the square, the triangle and the circle. These are forms that children get to know early in life and that return throughout the schooling. The idea is to use familiar but abstract forms to create conditions for children’s continued understanding, but also to give them opportunity to develop their own creativity and push their learning forward.

    A study on Friction Boundary Conditions with Unicorn/FEniCS-HPC2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to present and validate a boundary condition formulation for CFD problems that includes a friction parameter. In the first part of the thesis the incompressible Navier-Stokes system of equations and the friction boundary conditions are presented. Then the Finite Element methodology that is used to discretize the problem is given, with particular emphasis to the a-posteriori error estimate, the adaptive algorithm and the numerical tripping included in the flow. Moreover, since FEniCS-HPC is the software on which this thesis leans on, its framework is explained, together with its powerful parallelization strategy. Then the weak formulation of the Navier Stokes system of equation coupled with friction boundary conditions is presented, together with an initial theoretical derivation of the friction coefficient optimal values. Furthermore, in the last chapter, the preliminary results of a validation study for the lift coefficient of the NACA0012 airfoil benchmark model are included and commented in detail. Even if there still are some aspects to be elucidated, we believe that our preliminary results are very promising and that they open a new pathway for simulation development in aerodynamics-related models.

    Combinatorics of Macdonald polynomials and cyclic sieving2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis, we study the non-symmetric Macdonald polynomials E_λ (x;q,t) at t=0 from a combinatorial point of view, using the combinatorial formula found by J. Haglund, M. Haiman, and N. Loehr. Our primary focus is when λ is a partition. We summarize the known theory about this specialization and prove some new results related to this combinatorial formula. We also define the cyclic sieving phenomenon (CSP). For rectangular λ, we present an instance of cyclic sieving with E_λ (1,q,q^2,...,q^(k-1);1,0) as CSP-polynomial. We also conjecture another instance of CSP with E_λ (1,1,...,1;q,0) as CSP-polynomial. This conjecture generalizes a previously known CSP-triple. Furthermore, we prove this conjecture in the case when is λ an m×2 diagram.

    A Column Generation Method for Minimization of Shift Costs at an Airport2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis addresses the problem with minimizing the cost of labor shifts for the workforce at an airport. The cost of idle time is specifically a difficulty for the employer. With idle time means time that it is not a break at the same time as there is no work task to be performed. This originates from big variations in the traffic flow which lead to the workload to be characterized by peaks and valleys. This situation has increased the demand among airport service companies for efficient staff schedules. Even small reductions of the idle time mean considerable savings for the employer. This thesis uses authentic data from an international airport in Europe. The method used to solve the task is an algorithm based on column generation. The mathematical model used has a high flexibility and handles breaks, multi-activity, such as boarding, and non-splittable tasks, in other words tasks that has to be performed by one employee in one shift. The subproblem is a binary integer program that generates feasible shifts following certain rules and is solved using a commercial solver. The results have shown possible improvements. In the best test scenario, the idle time is reduced to 4.7 percent of the total worktime. There is room for improvement of the model and the results. One possible improvement is to reduce the running time of the program which also could lead to improved results.

    Proposal networks in object detection2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Locating and extracting useful data from images is a task that has been revolutionized in the last decade as computing power has risen to such a level to use deep neural networks with success. A type of neural network that uses the convolutional operation called convolutional neural network (CNN) is suited for image related tasks. Using the convolution operation creates opportunities for the network to learn their own filters, that previously had to be hand engineered. For locating objects in an image the state-of-the-art Faster R-CNN model predicts objects in two parts. Firstly, the region proposal network (RPN) extracts regions from the picture where it is likely to find an object. Secondly, a detector verifies the likelihood of an object being in that region.For this thesis, we review the current literature on artificial neural networks, object detection methods, proposal methods and present our new way of generating proposals. By replacing the RPN with our network, the multiscale proposal network (MPN), we increase the average precision (AP) with 12% and reduce the computation time per image by 10%.

    Design strategies for exploring and bridging: Intersections of everyday life and decisionmaking for sustainability2017In: Conference proceedings of the Design Management Academy: Research perspectives on creative intersections / [ed] Erik Bohemia ; Cees de Bont ; Lisbeth Svengren Holm, Glasgow, 2017, Vol. 1, p. 189-205Conference paper (Refereed)
    Abstract [en]

    Transitions of unsustainable everyday practices into more sustainable ones require new approaches to explore possible futures and encourage change. Trying new practices and experiencing alternative configurations of sociomaterial assemblages can increase reflexivity as well as assist in exploring potential futures. Design can assist in co-creating possible futures and bridging discussions about the preferred strategies to reach them. If sustainability is defined as an on-going process calling for dialogue, there could be potentials for using practice-based design research, and in particular co-design approaches, at the intersections of these dialogues. By analysing methods for reflexivity and collaboration in two design research projects within sustainable mobility, we here suggest design strategies for prototyping change at an individual level and communicating the experiences of such change to people with power to trigger and direct change. This may be particularly useful for addressing sustainability which both requires dealing with complex problems and extensive collaboration.

    Exploring Lost and Found in Future Images of Energy Transitions: Towards a Bridging practice of Provoking and Affirming Design2018In: DRS2018: Catalyst, 2018Conference paper (Refereed)
    Abstract [en]

    We need to transition our society in a more sustainable direction, for example through enormous cuts in carbon emissions. Yet this future is hard to envision and work towards. In this project, with a transition design posture, we have designed tools that we believe can be useful to initiate dialogues and reflections for the future. In particular we are interested in using the bridging between provocative and affirmative design as a way to explore and articulate what people see as the lost and found of such a transition. In this paper, we present a study where we used a practice lens to address one possible low carbon future through a provocation workshop. We present our methodology, the tentative tools we used during the workshop and the experiences as expressed by the workshop participants.

    Södertälje, a gateway to degrowth: A prospective design scenario to visualise the transition2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The project is an attempt to explore the concept of degrowth and its implications on the municipality of Södertälje, Sweden. Degrowth is brought as a critique of the dominant ideology of taken-for-granted economic growth and its inherent over-exploitation of resources. It is advanced as the new agenda for a different society and seeks to reduce its metabolism. A voluntary degrowth starts at the political level with a series of policies and regulations that eventually lead to a radical transformation of the urban fabric, structures, programmes and lifestyles. Therefore the project aims at visualising the transition from a growth-based society to one that favours environmental and social well-being over economic growth. Food production is brought in as the first agent of change, but other types of production come in thereafter. Three preferred areas have been chosen to illustrate the changes: an improved waterfront catalyzed by a food hub, a reconfigured city centre and a motor-oriented industrial area metamorphosed into a complex mix of housing and productive spaces.
