    A Simulation Framework for Efficient Search in P2P Networks with 8-Point HyperCircles2008Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [en]

    This report concerns the implementation of a simulation framework to evaluate an emerging peer-to-peer network topology scheme using 8-point hypercircles, entitled HyperCircle. This topology was proposed in order to alleviate some of the drawbacks of current P2P systems evolving in an uncontrolled manner, such as scalability issues, network overload and long search times. The framework is supposed to be used to evaluate the advantages of this new topology. The framework has been built on top of an existing simulator software solution, the selection of which was an important part of the development. Weighing different variables such as scalability and API usability, the selection fell on OverSim, an open-source discreet-event simulator based on OMNET++.

    After formalizing the protocol for easier implementation, as well as extending it for better performance, implementation followed using C++ with OverSim’s API and simulation library. Implemented as a module (alongside other stock modules providing their own protocols such as Chord and Kademlia), it can be used in OverSim to simulate a user-defined network using one of the simulation routine applications provided (or using a custom application written by the user). For the purposes of this thesis, the standard application KBRTestApp was used; an application sending test messages between randomly selected nodes, while adding and removing nodes at specific time intervals. The adding and removing of nodes can be configured with probability parameters.

    Tentative testing shows that this implementation of the HyperCircle protocol has a certain performance gain over the OverSim implementations of the Chord and Kademlia protocols, measurable in the time it takes a message to get from sender to recipient. Further testing is outside the scope of this thesis.

    Engagement in educational games and quality of life in early and middle childhood: evidence from a developing country2023Inngår i: Current Psychology, ISSN 1046-1310, E-ISSN 1936-4733, Vol. 42, s. 19386-19400Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Serious games (SGs), are gaining prominence as a tool for early education at home as well as in school settings. Given the mixed effects of gamification on various aspects of users' lives, it is pertinent to study its broader effects on a child's pre-school and school years. Given the lack of consensus on a comprehensive measure that encapsulates these effects on an individual's routine functioning, the present study examined whether various engagement states in SGs use influence a relatively broader measure of users' functioning across significant life domains such as Quality of Life (QoL). It is argued that it would serve scholars, teachers, and parents better to understand the broader implications of SGs on children's overall QoL rather than isolated physiological and behavioral effects. Consequently, utilizing structural equation modeling, results from 335 parents of 2-10-year-olds in a developing country showed that cognitive and behavioral engagement in gamified applications appear to influence the child's QoL, but not affective engagement. Results are discussed in terms of the consequences of using game-based technology for a child's development, with far-reaching academic, personal, physical, and social implications not only for the school-going ages, but also for early teenage years. The results are promising in relation to QoL. The findings indicate the role modern technology plays in improving individuals' lives. The findings provide scholars, parents, and creators of SGs important information for their plan of action regarding children's exposure to SGs and making SGs a frequent aspect of the learning experience early in life.

    Playing mind gamification: Theoretical evidence of addictive nature of gamification and identification of addictive game elements used in mobile application design2022Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Gamification is a modern concept that makes physical and digital activities engaging and enjoyable just like games. Game elements are added to mobile applications for user retention and engagement. One of the dark sides of gamification i.e., addiction is explored in this novel study in the context of mobile application design. It uses a mixed-method approach to lay the foundation of the relation between gamification and Smartphone Addiction, which is critically explained in a limited literature review using existing theories and studies on gamification. Interviews with behavioral experts confirm the psychological aspects of the research. The study also identifies game elements that contribute to smartphone addiction by a survey analysis of 269 participants. Results reveal Scrolling and Tapping as most addictive game elements. Some elements also show a statistically significant relationship with daily smartphone usage in hours. There are many effective applications of gamification, and in the context of mobile application design, it indeed helps to increase user engagement, however, there is an ethical need to reflect on what the exaggerated form of this engagement can lead to. As future research, a longitudinal study and experiments are suggested to find out this relationship with the use of empirical data.

    Exploring Software-Defined Networking Challenges in Sweden: IT Team Knowledge and Skills Gap2022Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Software-Defined Networking (SDN) is a new evolving approach within the networking domain. The concept is based on decoupling and abstracting the control and data plane of the traditional network devices. This separation facilitates the network operations with many benefits such as faster delivery, better segmentation, scalability, programmability, enhancing the quality of service and the quality of experience. Despite all the benefits, SDN has its own set of challenges. 

    The purpose of this study is to explore the main challenges in adopting SDN architecture in Swedish organizations. The focus is on the skills gap as one of the main challenges and how Swedish organizations were able to manage it.

    A qualitative approach has been chosen to conduct this research using semi-structured interviews to collect the data from seven different organizations, using a mixture of a purposive and snowball sampling selection. A thematic approach was then used to generate categories and themes from the collected data.

    The results are consistent with previous studies when it comes to technical, financial and security challenges. The technical challenges, however, were fewer in comparison with previous studies. A new way of working was presented as a new challenge when implementing SDN solutions. Furthermore, the knowledge gap was mentioned as a key challenge within Swedish organizations when implementing/operating SDN. 

    Finally, clear recommendations were made to overcome the knowledge gap challenge, from consulting a third-party expert, having a detailed plan, employing a multiphase process for SDN implementation, to having an online learning platform available to the IT team.

    The impact of a real-time IT-Logistics solution: Implementation effects and consequences2005Independent thesis Advanced level (degree of Magister), 10 poäng / 15 hpOppgave
    Abstract [en]

    Today’s business market is highly competitive, therefore companies need to be constantly updated and change the way they operate their business, in order to survive and remain competitive. The situation on today’s market requires that companies have the ability to quickly respond to market changes and new customer demands within short product lifecycles. In order to deal with this new market situation, companies need to improve the integration with other companies within their business. This integration facilitates the companies’ ability to quickly adapt to new market situations and survive on a fast changing market. One of the main underlying concepts of this collaborative commerce is Supply Chain Management (SCM) which integrates and coordinates a company’s processes both internally and externally. Information Technology (IT) could improve the effectiveness of SCM. IT-solutions make the business processes more effective and improves the integration with other actors within the supply chain. The purpose with this thesis is to describe and explain the effects for businesses and the consequences for its processes when implementing a real-time IT-Logistics solution together with identifying the critical success factors. The thesis has been conducted by studying theory regarding supply chain management, business renewal and implementation effects. Further, a case study has been conducted where three actors have been interviewed; a manufacturer (Volvo Powertrain), a subcontractor (Metallfabriken Ljunghäll AB) and a system developer (PipeChain). The analysis of the theoretical framework and the empirical research has contributed with an identification of major effects and consequences when implementing a real-time IT-Logistics solution. Some of the effects are: inventory reduction, higher delivery accuracy, improved relations and increased flexibility. Examples of consequences these effects have caused are: more accurate planning and production, effective production processes as well as an improved delivery process. Additionally, success factors for an implementation have been identified such as mutual trust, understanding of change and evaluation.

    Higher order mining for monitoring district heating substations2019Inngår i: Proceedings - 2019 IEEE International Conference on Data Science and Advanced Analytics, DSAA 2019, Institute of Electrical and Electronics Engineers (IEEE), 2019, s. 382-391, artikkel-id 8964173Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We propose a higher order mining (HOM) approach for modelling, monitoring and analyzing district heating (DH) substations' operational behaviour and performance. HOM is concerned with mining over patterns rather than primary or raw data. The proposed approach uses a combination of different data analysis techniques such as sequential pattern mining, clustering analysis, consensus clustering and minimum spanning tree (MST). Initially, a substation's operational behaviour is modeled by extracting weekly patterns and performing clustering analysis. The substation's performance is monitored by assessing its modeled behaviour for every two consecutive weeks. In case some significant difference is observed, further analysis is performed by integrating the built models into a consensus clustering and applying an MST for identifying deviating behaviours. The results of the study show that our method is robust for detecting deviating and sub-optimal behaviours of DH substations. In addition, the proposed method can facilitate domain experts in the interpretation and understanding of the substations' behaviour and performance by providing different data analysis and visualization techniques.

    Outlier Detection for Video Session Data Using Sequential Pattern Mining2018Inngår i: ACM SIGKDD Workshop On Outlier Detection De-constructed, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The growth of Internet video and over-the-top transmission techniqueshas enabled online video service providers to deliver highquality video content to viewers. To maintain and improve thequality of experience, video providers need to detect unexpectedissues that can highly affect the viewers’ experience. This requiresanalyzing massive amounts of video session data in order to findunexpected sequences of events. In this paper we combine sequentialpattern mining and clustering to discover such event sequences.The proposed approach applies sequential pattern mining to findfrequent patterns by considering contextual and collective outliers.In order to distinguish between the normal and abnormal behaviorof the system, we initially identify the most frequent patterns. Thena clustering algorithm is applied on the most frequent patterns.The generated clustering model together with Silhouette Index areused for further analysis of less frequent patterns and detectionof potential outliers. Our results show that the proposed approachcan detect outliers at the system level.

    A Minimum Spanning Tree Clustering Approach for Outlier Detection in Event Sequences2018Inngår i: The 17th IEEE International Conference on Machine Learning and Applications Special Session on Machine Learning Algorithms, Systems and Applications, IEEE, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Outlier detection has been studied in many domains. Outliers arise due to different reasons such as mechanical issues, fraudulent behavior, and human error. In this paper, we propose an unsupervised approach for outlier detection in a sequence dataset. The proposed approach combines sequential pattern mining, cluster analysis, and a minimum spanning tree algorithm in order to identify clusters of outliers. Initially, the sequential pattern mining is used to extract frequent sequential patterns. Next, the extracted patterns are clustered into groups of similar patterns. Finally, the minimum spanning tree algorithm is used to find groups of outliers. The proposed approach has been evaluated on two different real datasets, i.e., smart meter data and video session data. The obtained results have shown that our approach can be applied to narrow down the space of events to a set of potential outliers and facilitate domain experts in further analysis and identification of system level issues.

    Development of Web-based Health Care Services in Swedish County Councils: Strategies, Usage and Challenges2010Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    eHealth has been adopted by many countries across the globe in response to cut down cost and improve the quality of life. Sweden has been engaged in providing web-based health care services for its citizens for the past decade and county councils have the responsibility to develop them. The main aim of this thesis is to present answers to the following research questions:What strategies (formal and informal) guide the development of web-based health care services provided by the Swedish county councils?What barriers exist in relation to the development and usage of web-based health care services provided by the county councils from the viewpoint of their IT leaders?From the perspective of IT leaders in the county councils and in their capacity to develop, manage and monitor their organizations‘ website content, which web-based health care services are mostly accessed by users and what age group utilize the services most?The thesis is an exploratory research conducted through a survey based on a mail questionnaire that was posted to all 21 county councils in Sweden with 18 councils responding. The results show that all county councils have formally adopted the National eHealth Strategy to guide the development of web-based health care services and some have other informal strategies as well. Technological barriers, resistance to use the web-based services and changing business process to integrate ICTs have been identified by IT leaders as major challenges that impede the development of web-based health care services in Swedish county councils. Swedish citizens more frequently access prescription renewal and booking and cancellation of appointments than other available web-based health care services which depicts a trend towards the use of advanced interactive services than basic information seeking, and people in the ages of 46 to 55 have been identified as the frequent users of web-based health care services according to IT leaders from the county councils.

    Business models for telemedicine services: A literature review2015Inngår i: Health Systems, ISSN 2047-6965, E-ISSN 2047-6973, Vol. 4, nr 3, s. 189-203Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Telemedicine has been acknowledged to improve the quality of healthcare. However, many telemedicine services fail beyond the pilot phase. A literature review on business model components for telemedicine services was conducted. Based on specified inclusion criteria, 22 publications were included in the review. To facilitate the analysis of literature, a business model framework with value as its central focus was proposed. Improvement in quality, efficiency and accessibility of care were identified to be the outcomes of telemedicine, with patients and healthcare personnel being the main users of the services, which are delivered through home, institutional and community-based care. Patients, health providers, vendors, payers and government agencies are actors involved in the delivery of telemedicine services, which require investments in resources like videoconferencing technologies, home monitoring devices and other IT infrastructure. Subscriptions, reimbursements and pay-per-use revenue streams were identified as feasible for commercializing telemedicine services.

    Effects of a Home-based Monitoring Device on Innovation in Healthcare Delivery: A Pilot Study2013Inngår i: Information Systems and Technology for Organizations in a Networked Society / [ed] Tomayess Issa, Pedro Isaias and Piet Kommers, Hershey, PA, USA: IGI Global, 2013, s. 316-334Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    Information technology has been suggested to improve patient health outcomes and reduce the burden of care. In this study, we explored the effects of collaborative innovation between caregivers and patients on healthcare delivery as a consequence of the use of an IT-based device by patients with atrial fibrillation. Two cardiologists and two nurses were interviewed while questionnaires were mailed to 75 patients querying them about the use of a home-based ECG for remote monitoring. Findings indicated that the caregivers considered the device to enhance the quality of clinical decision-making. Patients found the device to be useful and felt more involved in their own care. However, the introduction of the device presented work overload for the caregivers. Thus, the facilitation of timely diagnostics and decision-making were not realized. IT is an enabler through which innovation in healthcare delivery can be realized, but it must be integrated into work practices to realize potential benefits.

    Knowledge management cloud-based solutions in small enterprises2015Independent thesis Advanced level (degree of Master (Two Years)), 30 poäng / 45 hpOppgave
    Abstract [en]

    Purpose – The aim of this study is to determine if adopting cloud-based knowledge management is a viable way forward for small enterprises and to investigate what are the main factors that might facilitate or inhibit these companies to adopt such solutions.Design/Methodology/Approach - In order to understand the main factors that could influence the adoption of a cloud-based knowledge management solution in small enterprises, I used a qualitative research approach, based on four semi-structured interviews with four small companies from Romania.Findings – The results of the study suggest that implementing knowledge management in the cloud is particularly beneficial for small enterprises, as a lower investment in IT infra-structure can create a competitive advantage and help them implement knowledge man-agement activities as a strategic resource. Moreover, the study suggests that relative ad-vantage, compatibility and technology readiness will influence companies in moving their knowledge to the cloud. Also, the study reveals that companies which did not adopt such a solution had already established systems for managing knowledge and failed to realize its benefits, it was not perceived as needed, they had a low level of awareness or cited security and uncertainty reasons.

    Balancing walled garden and open platform approaches for the Internet of Things: A case study of Husqvarna Group2016Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The term “Internet of Things” (IoT) was first introduced by a technology pioneer Kevin Ashton in 1999.Although the term is relatively new, the idea of making networks and computers communicate in order totrack and manage devices has been around for many years. As of now IoT is a rising topic in technicalcommunity. Some specialists are anticipating that by 2025 there will be around 100 billion connected IoTdevices with a worldwide economic impact of more than $11 trillion. On the other hand, Internet of Thingsemerges significant challenges. Currently the organization around world use two main approaches whenentering the IoT market. First one is an open platform and is represented by interoperability andcollaboration with devices from different vendors. Second one is a closed platform, or a “walled garden”approach. A “walled garden” approach is characterized by building “fences” around the user. In other words,the service provider has control over applications, content and media and also restricts the non-approvedcontent to reach the customer. Therefore, the research set out to explore these approaches and show thebenefits and limits they can have on an organization. The research was conducted in collaboration with aSwedish manufacturer of outdoor power products called Husqvarna Group. In order to fully acknowledgethe organization’s approach, 4 interviews were conducted with managers, back end developers andconsultants hired by Husqvarna Group. From the findings, some things should be taken in consideration.First, IoT involves big data being collected, therefore security and privacy are crucial when developingdevices and systems. Second, it is essential for an organization to have the same views when taking a newdirection. Third, when discussing Internet of Things, it means that things connect, devices to sensors,sensor to gateways and gateways to system. And there shouldn’t be a delimitation from a vendor to another.Therefore, open platform approach is seen as the way to diversity and innovation.

    Customer Maturity Analysis Tool: A case study in designing a Customer MaturityAnalysis Tool2010Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The IT consultancy industry is characterized by knowledge intensive implementationprojects related to varying levels of standardized information system software. When faced with a large implementation project at a previously unknown customer various assessmentsis usually conducted to identify the level of fit between the software and organizationin order to plan and structure the implementation process. However, there are several aspects of the customer organization that potentially can affect the end result as well as the implementation process that is unrelated to the fit between the software and the implementation organization as well as the potency of the implementation method. By conducting measurements of these maturity factors within the customer organization the implementing procedure can be modified based on the customer maturity level in order to become more aligned with the capabilities present in the customer organization.

    Research question: Which aspects need to be covered by a Customer Maturity Analysis Tool (CMAT) in order to evaluate the pre implementation maturity for potential customersof our case company and how should these aspects be organized and measured? The first task of the research process was to create an underlying model of maturity perspectives and aspects to structure the literature review as well as the empirical data collection. It was decided to adhere to a deductive approach where the theoretical model would be validated and if necessary modified in accordance to feedback from potential users of the CMAT within the case company. This procedure was repeated in the creation of measurements and maturity levels for the aspects to be used in the tool. The research process would therefore transition from a general model based on literature review, through a iterative feedback loop to a final model tailored to the specific requirementsof the case company. The final CMAT ended up containing four main perspectives of customer maturity; ITi nfrastructure, Culture, Process and Business Governance. These four perspectives were in turn divided into subgroups in order to be able to aggregate and compare differentaspects of the perspectives with each other.

    Not-Too-Deep Channel Charting (N2D-CC)2022Inngår i: 2022 IEEE Wireless Communications and Networking Conference (WCNC), IEEE, 2022, s. 2160-2165Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Channel charting (CC) is an emerging machine learning method for learning a lower-dimensional representation of channel state information (CSI) in multi-antenna systems while simultaneously preserving spatial relations between CSI samples. The driving objective of CC is to learn these representations or channel charts in a fully unsupervised manner, i.e., without the need for having access to explicit geographical information. Based on recent findings in deep manifold learning, this paper addresses the problem of CC via the "not-too-deep" (N2D) approach for deep manifold learning. According to the proposed approach, an embedding of the global channel chart is first learned using a deep neural network (DNN)-based autoencoder (AE), and this embedding is subsequently searched for the underlying manifold using shallow clustering methods. In this way we are able to counter the problem of collapsing extremities - a well known deficiency of channel charting methods, which in previous research efforts could only be mitigated by introducing side-information in form of distance constraints. To further exploit the ever-increasing spatio-temporal CSI resolution in modern multi-antenna systems, we propose to augment the employed AE with convolutional neural network (CNN) input layers. The resulting convolutional autoencoder (CAE) architecture is able to automatically extract sparsely distributed spatio-temporal features from beamspace domain CSI, yielding a reduced computational complexity of the resulting model.

    On the selection of relevant historical demand data for revenue management applied to transportation2023Inngår i: Journal of Revenue and Pricing Management, ISSN 1476-6930, E-ISSN 1477-657X, Vol. 22, nr 4, s. 266-275Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The success of revenue management models depends to a large extent on the quality of historical data used to forecast future bookings. Several theoretical models and best practices of handing historical data have been developed over the years, that all rely on assumptions about underlying distribution and seasonality in the historical data. In this paper, we describe a novel method that compares the fingerprints of the departure to optimise and selects historical departures without making assumptions on data distribution or seasonality. By evaluating the method at the departure level and using the Nemenyi rank test, we show the method’s application in the ferry transportation business and discuss its advantages.

    Using conformal prediction to prioritize compound synthesis in drug discovery2017Inngår i: Proceedings of Machine Learning Research: Volume 60: Conformal and Probabilistic Prediction and Applications, 13-16 June 2017, Stockholm, Sweden / [ed] Alex Gammerman, Vladimir Vovk, Zhiyuan Luo, and Harris Papadopoulos, Machine Learning Research , 2017, s. 174-184Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The choice of how much money and resources to spend to understand certain problems is of high interest in many areas. This work illustrates how computational models can be more tightly coupled with experiments to generate decision data at lower cost without reducing the quality of the decision. Several different strategies are explored to illustrate the trade off between lowering costs and quality in decisions.

    AUC is used as a performance metric and the number of objects that can be learnt from is constrained. Some of the strategies described reach AUC values over 0.9 and outperforms strategies that are more random. The strategies that use conformal predictor p-values show varying results, although some are top performing.

    The application studied is taken from the drug discovery process. In the early stages of this process compounds, that potentially could become marketed drugs, are being routinely tested in experimental assays to understand the distribution and interactions in humans.

    IoT for Health and Well-being: A case study and call for action2023Inngår i: PETRA '23: Proceedings of the 16th International Conference on PErvasive Technologies Related to Assistive Environments, Association for Computing Machinery (ACM), 2023, Vol. 16, s. 465-467Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this short paper we describe the implementation of an IoT test-bed in an elementary school. We argue that by adding additional IoT senors to an existing IoT system it is possible to evolve an indoor climate control system into a indoor milieu control system aimed at improving the health and well-being for both pupils and staff who spend their days working in the school environment. Lastly, we call for multidisciplinary action as the domain IoT for health and well-being spans across several different knowledge domains.

    The Perfect Match: RIS-enabled MIMO Channel Estimation Using Tensor Decomposition2023Manuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    The deployment of reconfigurable intelligent surfaces (RISs) in a communication system provides control over the propagation environment, which facilitates the augmentation of a multitude of communication objectives. As these performance gains are highly dependent on the applied phase shifts at the RIS, accurate channel state information at the transceivers is imperative. However, not only do RISs traditionally lack signal processing capabilities, but their end-to-end channels also consist of multiple components. Hence, conventional channel estimation (CE) algorithms become incompatible with RIS-aided communication systems as they fail to provide the necessary information about the channel components, which are essential for a beneficial RIS configuration. To enable the full potential of RISs, we propose to use tensor-decomposition-based CE, which facilitates smart configuration of the RIS by providing the required channel components. We use canonical polyadic (CP) decomposition, that exploits a structured time domain pilot sequence. Compared to other state-of-the-art decomposition methods, the proposed Semi-Algebraic CP decomposition via Simultaneous Matrix Diagonalization (SECSI) algorithm is more time efficient as it does not require an iterative process. The benefits of SECSI for RIS-aided networks are validated with numerical results, which show the improved individual and end-to-end CE accuracy of SECSI.

    Transforming Requirements to Ontologies2020Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Capturing client’s needs and expectations for a product or service is an important problem in software development. Software requirements are normally captured in natural language and mostly they are unstructured which makes it difficult to automate the process of going from software requirements to the executable code. A big hurdle in this process is the lack of consistency and standardization in software requirements representation. Thus, the aim of the thesis is to present a method for transforming natural language requirement text into ontology. It is easy to store and retrieve information from ontology as it is a semantic model, and it is also easy to infer new knowledge from it.

    As it is clear from the aim of this work, the main component of our research was software requirements, so there was a need to investigate and decide the types of requirements to define the scope of this research. We selected INCOSE guidelines as a benchmark to scrutinize the properties which we desired in the Natural Language Requirements. These natural language requirements were used in the form of user stories as the input of the transformation process. We selected a combination of two methods for our research i.e. Literature Review and Design Science Research. The reason for selecting these methods was to obtain a good grip on existing work going on in this field and then to combine the knowledge to propose new rules for the requirements to ontology transformation. We studied different domains during literature review such as Requirements Engineering, Ontologies, Natural Language Processing, and Information Extraction. The gathered knowledge was then used to propose the rules and the flow of their implementation. This proposed system was named as “Reqtology”. Reqtology defines the process, from taking the requirements in form of user stories, to extracting the useful information based on the rules and then classifying that information so that it can be used to form ontologies. The workflow consists of a 6-step process which starts from input text in form of user stories and at the end provides us entities which can be used for ontologies formation.

    Exploring Young Male Perspectives on Gender-Stereotyped Instagram Ads: A qualitative study on Swedish men's engagement towards gender-stereotyped advertisements in the digital context of Instagram2023Independent thesis Basic level (degree of Bachelor), 180 hpOppgave
    Abstract [en]

    This paper examined male engagement towards gender stereotypes online. We specifically sought to address how men engage with gender-stereotyped advertisements on Instagram, and which interactions they utilize to do so. We aimed to understand how men engage with gender stereotypes in Instagram advertisements by answering the following research question:

    [RQ1] How do men engage with gender-stereotyped advertisements on Instagram?

    Data were collected from 10 male participants through semi-structured interviews using photo elicitation. The data was further obtained through thematic analysis using the Theory of Planned Behaviour. The findings resulted in 26 codes and 6 themes. The results demonstrated that exposure to masculine content receives more attention and recognition than feminine, non-sexualized content. The findings argued that men are hesitant to engage with sexualized and provocative content due to societal norms and fear of being judged by others. In contradiction, men believe that other men are more likely to engage with sexualised, gender-stereotyped content that idealizes masculinity. The study identified the most common engagement interactions utilized when engaging with gender-stereotyped content: liking, visiting the account or website, and sharing content with a friend.

    The findings supported previous research claims that accepting a feminine image puts men at risk of violating gender roles, resulting in men preserving a masculine persona by distancing themselves from this type of material (Elliot & Elliot, 2005). Additionally, we concluded that fear of judgement from peers and society results in social pressure to conform to masculine gender norms, which may influence men’s online behaviour.

    The results may be delimited by social desirability and sampling bias due to the designated scope. Nevertheless, we have implemented measures to ensure the trustworthiness of this study.

    Challenges for heart failure patients’ self-care systems – analysis of patients’ needs2014Inngår i: Procedia Technology, E-ISSN 2212-0173, Vol. 16, s. 1256-1264Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Self-care is important for heart failure patients. However, what are the views of patients on their situation when it comes to realizing self-care? The aim of the paper is to investigate the self-care needs of HF patients, by understanding the issues they embrace in their self-care processes. In this paper we make a review of 17 interviews and make a classification of what the needs are for possible information technology support systems. Based on the analysis of these interviews, we identify the diversity of needs in support of activities related to different background conditions and the dynamics of change of learning and changes in the heart failure condition. The contribution of the paper is a framework for understanding the diversity of needs and the specific situations of this group of patients.

    Exploring the governance of IT in SMEs in Småland2012Independent thesis Advanced level (degree of Master (One Year)), 40 poäng / 60 hpOppgave
    Abstract [en]

    With many research available on IT governance, this research differs from most of them due to its delimitation. The focus of this research lies in the two domains of value creation and performance measurement. Furthermore, the area of research has been small and medium Enterprises located in the area of Småland, Sweden.

    Brisebois, Boyd & Shadid (2001) gave us the following definition of IT governance: “How those persons entrusted with governance of an entity will consider IT in their supervision, monitoring, control, and direction of the entity. How IT is applied will have an immense impact on whether the entity will attain its vision, mission, or strategic goal.”

    An objective of IT governance is to align the IT resources of an enterprise in a way that it fast-tracks the business priorities of the enterprise and assures that the investments in IT generates business value and that the IT is performing to its expectations.

    The research questions and the outcome of this research paper sheds light on the challenges of both value creation and performance measurement within the SMEs, but it also showcases what the driving forces of IT value creation are and which benefits arise from measuring the IT performance within the SMEs.

    Through semi-structured interviews with four SMEs, based in the region of Småland, numerous amounts of challenges and driving forces for IT value creation and challenges and benefits to measuring IT performance have been extracted.

    Based on the extracted information from the interviews, an analysis and a conclusion have been formed by the authors. In the end, the authors provide their thoughts for suggestions for further work and how all of this contributes to the field of Informatics.

    Exploring the Integration of Enterprise Systems Solutions Within A Supply Chian2011Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Over the decades, as organizations begin to move globally there has been a sporadic flow of information in their supply chain. Competition today is forcing companies to integrate tightly with their suppliers and customers, in order to reduce the time available to flex the supply chain (SC) (Koh S.C, Saad S, Arunachalam S, 2006). The integration of firms and departments and information is getting more and more complicated. Regardless of enterprise system solutions being introduced as “integrated suites” they have failed to accomplish application and supply chain integration (Themistocleous, M. Irani, Z. O‟Keefe, and R. 2001). Therefore, this thesis aims to explore, gain better understanding and to explain the balance that may occur between the challenges and benefits gained from integrating enterprise resource planning and supply chain management.Our topic of interest could be view from both developers and user perspective. Developer/consultant‟s perspective is based on the viewpoint of those involved in and responsible for developing enterprise solutions. User‟s perspective, this perspective gives insight to how the integration process is perceived by organisations actually using the solutions. We chose the User perspective because we consider the user to be the direct beneficiary of whatever outcome is gotten from both the business solutions and its integration.In order to achieve a purposeful thesis. We decided to use an interpretive perspective which focus on exploring and gaining insight into issues of integrating enterprise system solution. We used both the inductive and the deductive approaches in our research. This would be advantageous due to the nature of our research topic, as there is little existing knowledge about the integration of enterprise systems solution within supply chain and there are lots of literatures related to the enterprise system solutions (ERP and SCM) been observed. The inductive approach would guide us to choose one or a few specific interactions to explore in-depth, while the deductive approach would aid us when making an hypothesis, since we would be collecting ideas about previous research and theories in order to guide us and make comparison.Conclusively, we found that the balance between challenges and benefits of ERP and SCM are unequivocal, as the benefits surpass the challenges and the effect of challenges on organisation‟s benefit is that it prolongs the short term benefit.

    Improving Researcher-Patient Collaboration through Social Network Websites2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Purpose: The main purpose of this study/thesis is to, through an interview with researchers in medical field in Jönköping,  provide an empirical analysis of the link or relationship between medical researcher and patient through social networking sites specifically for collaboration in order to improve relationships, dissemination of information and knowledge sharing.

    Background: The importance of social networking websites as a means of interaction between groups of individuals cannot be underestimated. Their impact on daily life activities and activities cannot be underestimated. Because  millions of individuals are making use of Social Network Sites (SNSs) to build or reinforce relationships, connect, disseminate and share information as well as sharing of knowledge whether personal or non-personal experiences with people they already know offline or new people online. Therefore, the authors are interested basically in how social networking web sites are being utilized in terms of collaborations, information and knowledge sharing and particularly in what benefits and challenge are connected to improving inter-groups collaboration in research study between researchers and ordinary citizens.

    Method: A review of literature gives us insight about the subject terms, critical and sensitive issues in regards to collaboration through social networking sites designed for research purpose. We apply in general networking theories such as social capital and two of its components couple with Putman´s theory of bonding and bridging social capital as a theoretical framework to synthesize the concept of  ties (strong or weak) . Our analysis based on the empirical data gathered through surveys, interviews and observation provide us with interesting preliminary results and with blueprints to guide the analysis of the thesis.

    Conclusion: Social networking platforms are valuable and useful in our generation being part of daily life and activity to keep up with people within our networks. However, the authors discovered that the advantages of involving ordinary citizens to participate in improving researcher-patient collaboration through dynamic social networking actually outweigh the disadvantages despite all odds and sensitive issues such as trust, privacy issues and sceptics of some researchers. In others words, some of the researchers were enthusiastic to collaborate in terms of disseminating useful information and sharing valuable knowledge with ordinary citizens. Overall, the study revealed positive result that despite weak ties relationships, the willingness to collaborate is far more than the obstacles perceived in the course of establishing such collaboration.

    INTERNET OCH PERSONER MED FUNKTIONSHINDER2009Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    People with disabilities constitute a big group of Internet users. Due to great advances in adaptive technology for people with disabilities more and more disabled will have access to Internet. For that reason it is extremely important for a web developer to be aware of different disabilities that complicate or prevent using Internet, different adaptive technologies that facilitate using Internet and different methods, both in design and programming, that make Internet accessible for people with disabilities.

    In this report we have dealt with three problems:

    • Which types of disabilities that complicate or prevent using Internet?

    • Which types of adaptive technologies are available concerning using Internet?

    • How can a web developer or programmer increase the accessibility to Internet for people with disabilities?To investigate how disabled people use adaptive technologies and which difficulties they experience when using Internet we have interviewed people with various types of disabilities.

    Impact of Intrinsic Factors and COVID-19 Pandemic on the Use of Technology2021Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The unprecedented pandemic of the infectious coronavirus disease (COVID-19) is still ongoing. Considering the limitations and restrictions imposed by COVID-19, we explored the role of technology and the extent of usage by end-users. In our online survey, we investigated users’ perspectives on their use of technologies in different contexts (e.g., work, entertainment), taking into consideration intrinsic factors such as health consciousness, perceived social isolation, and pandemic-related concerns. Results from 218 respondents show a significant increase in technology use in all investigated contexts after the pandemic occurred. Moreover, the results suggest that different factors may contribute to such increases, depending on the context. It appears that perceived social isolation, concerns about the pandemic, and tracking have the most prominent influence on different use of technology. Furthermore, open-ended responses include beneficial opportunities, concerns & consequences, and behavioral transformations & adaptations due to COVID-19. Our findings provide insights for designing and developing new technologies, especially for communication and entertainment, to support users’ needs during a pandemic.

    Software patterns have been proven as a valuable way to storing a repeatable solution to a commonly occurring problem in software design. A pattern is not a finished design that can be directly formed into program code; instead it is a description how to solve a problem that may occur in many situations.

    In the ontology community very little research have been made in producing high-level patterns where the solution shows how an architecture of an ontology based software might look like.

    In this thesis the results of examining how high-level patterns of this type relates to other types of patterns are given and how these patterns would be described are formulated.

    Describing Ontology Applications2007Inngår i: Proceedings of the 4th Annual European Semantic Web Conference (ESWC 2007), 2007Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Semantic Web technologies are finally, after a few years of infancy, truly entering the business world to support the growing needs of computer aided information selection and processing. There are already quite well-defined development processes and methods in the software engineering field to handle the construction of large scale and complex enterprise systems, and to reuse knowledge in different software domains patterns are considered to be common practise. Patterns can be described on different levels of abstraction, but the patterns in the focus of this paper are on the software architecture level. In this paper we present a definition of the notion ”ontology application pattern”, as a special form of software architecture patterns describing an ontology-based system. We also show how such patterns, as well as the description of the pattern instantiations, can be described using a modified architecture description language.

    Abstract [en]

    A clear understanding of the organizational competences of anenterprise and the underlying individual competences and the competencedevelopment needs has become more and more important for many industrialareas as a foundation for competence supply processes and adjustment tochanging market conditions. Competence modelling, i.e. the use of enterprisemodelling techniques for capturing existing and describing desiredorganisational and individual competences in enterprises, offers importantcontributions to this. In the last years, the authors of the paper have performed anumber of competence modelling cases, which revealed different characteristicsand resulted in lessons learned. This paper presents an examination of differentcharacteristics of competence modelling cases, and recommendations andlessons learned from these cases for the practice of competence modelling.

    Att arbeta aktivt med språkutveckling i förskolan för att främja barn med annat modersmål.: En kvalitativ intervjustudie om hur förskollärare  beskriver arbetet med språkutveckling2023Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Studiens ämne är språkutveckling med fokus på barn med annat modersmål. Där syftet med studien är att undersöka hur förskollärare beskriver sitt arbete med att främja språkutvecklingen hos de barn som har svenska som andraspråk. Studiens forskningsfrågor är: hur beskriver förskollärarna att de arbetar med barns språkutveckling? vilka metoder kan användas för att främja svenska som andraspråk enligt förskollärarna? Den teoretiska utgångspunkten för studien har varit det sociokulturella perspektivet. För att besvara syftet och frågeställningarna har sex förskollärare intervjuats med hjälp av kvalitativa metoder.   Resultatet visar att förskollärarna arbetar aktivt för att främja barn med ett annat modersmål, där olika arbetssätt och metoder framkom. Arbetssätten var främst TAKK och bildstöd. Polyglutt är ett annat verktyg som nämns av flera förskollärare, som används för att främja både modersmålet, samt andraspråket. I resultatet framkommer att förskollärarna uppmanar vårdnadshavare att tala modersmålet med barnen för att deras språkutveckling ska föras framåt, då modersmålet är en viktig tillgång i förskolans verksamhet. Modersmålet är en bidragande faktor vid inlärningen av ett andraspråk där ingen förskollärare anser inlärningen som negativ. Vikten av att vårdnadshavarna visar intresse och nyfikenhet i arbetet framkommer tydligt i både litteratur och i intervjuerna.

    Kravfylld design.: En studie i hur Requirements Engineering, sociala relationer och kommunikation kan samverka för en förbättrad hantering av kundkrav inom grafisk kommunikation.2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syfte – Idag saknas det ett standardiserat arbetssätt för att hantera kundkrav samtidigt som det finns stora utmaningar i hanteringen av dem. Därmed är syftet med denna studie:

     Att definiera ett ramverk för hantering av kundkrav inom Grafisk kommunikation.

    För att kunna besvara syftet i studien har en frågeställning tagits fram som utgångspunkt för studien.

    Hur kan Requirements Engineering, sociala relationer och kommunikation tillsammans bidra till att förbättra hantering av kundkrav inom arbetet med Grafisk kommunikation?

    Metod – För att besvara frågeställningen har studien arbetat med datainsamlingsmetoden, semistrukturerade djupintervjuer. Intervjuerna har genomförts  för att få fram primärdata. Metoden har valts ut för att säkerställa en kvalitativ ansats i studien. I studien har även litteraturstudier genomförts som en viktig del med syfte att ge en bakgrund kring befintliga teorier, metoder och verktyg.

    Resultat – Studien är av tvärvetenskaplig art och dess resultat behandlar områden så som Requirements Engineering, Grafisk kommunikation, sociala relationer och kommunikation. Områdena har studerats för att se hur de kan samverka för att säkerställa en högre och jämnare nivå av de projektresultat som reklambyråer och konsulter inom reklam- och kommunikationsbranschen levererar. Studien resulterade i ett ramverk för hantering av kundkrav inom Grafisk kommunikation. Ett ramverk beståendes av två olika kategorier som berör både den praktiska processen samt den social kommunikativ dimensionen kopplat till hantering av krav. Studiens resultat beskriver också vilka element som bör finnas i en iterativ designprocess samt hur ramverket kan användas tillsammans med en sådan typ av utvecklingsprocess.

    Implikationer – Studien anses kunna bidra till forskningsvärlden då dess resultat har öppnat upp nya dörrar för ytterligare områden att applicera Requirements Engineering på. För näringslivet och det vardagliga arbetet inom reklam- och kommunikationsbranschen har resultatet visat att ramverk för hantering av kundkrav inom Grafisk kommunikation bör kunna medverka till att stödja verksamheters arbetsprocesser och säkerställande av en mer jämn kvalitetsnivå. Utvecklingsprocesser och dess slutresultat skulle ha större möjlighet att bli framgångsrika, samtidigt som användningen av projektets resurser med stor sannolikhet skulle kunna effektiviseras genom den struktur som ramverket för med sig.

    Web Accessibility and Search Engine Optimization: an investigation on the implementation and its effect within e-commerce websites in Sweden2021Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    With the digital world we live in today, inclusion on the web is crucial. Ensuring all who want to access the web can do so is a responsibility that can be vague. As prior research has shown that making a website accessible is a low prioritized matter because of time and money, but also lack of knowledge, the purpose with this thesis was to find out if factors used for search engine optimization could cater to web accessibility. There is a general understanding that there are overlapping factors between the two concepts. Since search engine optimization is a desired and successful part of providing a website with traffic, an overlap should improve accessibility. To understand in what way the search engine optimization factors could affect the accessibility of a webpage as a whole, with this thesis we go into the context of implementation by interviewing web professionals. As this thesis will show, there are multiple aspects needed to be taken into consideration when measuring to what extent the overlapping factors affect website performance in regards to accessibility. Factors like the clients, thoughts about responsibility, experience and even personal interest come into play. The method used was qualitative where we analysed the data with a thematic analysis and descriptive statistics. The data collection had three parts: a survey, an in-depth interview with a few of the participants from the survey, and finally a web performance test. The latter was performed by Siteimprove crawl, which administers one of the top accessibility ranking tools online. The general indication was that we cannot draw a conclusion to the benefit of it being enough to just implement the SEO factors that overlap. Although, this investigation provides an insight into to what extent web professionals are implementing the overlapping factors between search engine optimization and web accessibility, and what other aspects may influence web performance.

    Riktlinjer för grafiska användargränssnitt för lagersystem2016Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syftet med denna rapport är att undersöka och sammanställa riktlinjer för att utveckla ett grafiskt användargränssnitt för ett lagersystem. För att uppnå syftet med rapporten litteraturstudier, intervjuer, observationer och en prototyputveckling utfördes. Utifrån litteraturstudier visade det sig att det inte fanns specifika designriktlinjer för utveckling av lagersystem fast det fanns allmänna riktlinjer som kan användas för design av olika system. Intervjuer med utvecklare och en utvecklingschef på företaget Qsys hjälpte till att hitta befintliga riktlinjer som företaget använder. Det visade sig att de använder allmänna riktlinjer som inte är specifika för lagersystem. För att hitta mer specifika riktlinjer observerade vi några lagerarbetare för att bättre förstå hur de integrerar med det befintliga systemet som de använder. Utifrån analysen av observationerna, upptäcktes det nya riktlinjer. Med hjälp av de allmänna riktlinjer som hittades i litteraturen och riktlinjer som upptäckes efter analysen av observationer, utvecklade vi en prototyp som sedan testades. Resultatet vi fick utifrån analysen av intervjuerna med lagerarbetarna efter prototyptestning, hjälpte med att hitta ytterligare specifika riktlinjer.För att utveckla ett användarvänligt lagersystem, behöver man ett användarvänligt gränssnitt. I denna rapport presenterar vi några riktlinjer som man kan använda sig av för att utveckla ett användarvänligt gränssnitt för lagersystem.

    Locating faults in boundary wires for autonomous lawn mowers: An investigative study on methods used to locate faults in underground, low-voltage cables with focus on implementing Time Domain Reflectometer (TDR)2021Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Purpose:The purpose of this thesis was to identify a useful solution to find the location of a broken boundary wire. By useful we mean that the solution should be inexpensive, user friendly and accurate. However, this thesis will only investigate the accuracy of the method where the hypothesis is that an investigated method is applicable for all underground wires.

    Method:This study conducted a literature research in order to investigate what methods that are used in other industries to locate faults in underground, low-voltage electrical wires. After the research, the most commonly used fault locating methods were described and the one that seemed most useful was chosen as a possible solution.For the solution to be useful the accuracy was investigated. The method used to conduct an experiment and gather data to validate the solution was Design Science Research.

    Result:Three methods were investigated as possible solutions:Time Domain Reflectometry (TDR), Frequency Domain Reflectometry (FDR) and Murray bridge where experiments were conducted using TDR.TDR proved to be unapplicable in locating faults in boundary wires, although it was confirmed to be a valid solution to locate faults in coaxial cables with <1% error margin.What makes TDR and other reflectometry methods unsuitable methods within the autonomous lawn mower industry is the lack of characteristic impedance in the used boundary wires. The hypothesis that an investigated method is applicable for all underground wires is thereby refuted.

    Limitations:Experiments were conducted in laboratory environment with a signal generator and an oscilloscope. One experiment was conducted on a boundary wire in the ground which provided no reflected signal.
