    A Simulation Framework for Efficient Search in P2P Networks with 8-Point HyperCircles2008Självständigt arbete på avancerad nivå (magisterexamen), 20 poäng / 30 hpStudentuppsats
    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 country2023Ingår i: Current Psychology, ISSN 1046-1310, E-ISSN 1936-4733, Vol. 42, s. 19386-19400Artikel i tidskrift (Refereegranskat)
    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 design2022Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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 Gap2022Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Software-Defined Networking (SDN) är en framväxande teknik inom nätverksdomänen. Konceptet är baserat på att frikoppla och abstrahera kontrollplan och dataplan för de traditionella nätverksenheterna. Separationen underlättar nätverksdrift och ger många fördelar såsom, snabbare leverans, bättre segmentering, skalbarhet, förbättrade kvalitet på tjänsten och kvalitet på upplevelsen. Trots många fördelar har SDN också utmaningar.

    Syftet med denna studie är att utforska de största utmaningarna med att implementera SDN-arkitektur i svenska organisationer. Fokus ligger på kunskapsklyftan som är en av de tidigare identifierade huvudutmaningarna, och hur svenska organisationer har hanterat dessa.

    En kvalitativ metod har valts för att genomföra denna studie med hjälp av semistrukturerade intervjuer för att samla in data från sju olika organisationer, med hjälp av en blandning av målinriktat och snöbollsurval. En tematisk metod användes sedan för att generera kategorier och teman från den insamlade datan.

    Resultaten överensstämmer med tidigare studier när det gäller tekniska, ekonomiska och säkerhetsmässiga utmaningar. De tekniska utmaningarna var dock färre jämfört med tidigare studier. Ett nytt arbetssätt presenterades som en ny utmaning vid implementering av en SDN-lösning. Dessutom, nämndes kunskapsklyftan som en central utmaning inom svenska organisationer vid implementering och drift av SDN. Slutligen presenterades tydliga rekommendationer för att övervinna utmaningen med kunskapsgapet, från att konsultera en tredje part, att ha en tydlig plan, använda en flerfasprocess för SDN-implementering samt att ha en digital utbildningsplattform tillgänglig för IT-teamet.

    The impact of a real-time IT-Logistics solution: Implementation effects and consequences2005Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats
    Abstract [sv]

    Konkurrensen är stor inom dagens affärsmarknad vilket medför att företag ständigt måste vara uppdaterade och förändra deras affärsverksamhet för att kunna överleva och vara konkurrenskraftiga på marknaden. Dagens marknadssituation erfodrar att företag snabbt kan reagera på marknadsförändringar och nya kundkrav vid allt kortare produktlivscyklar. För att företag skall kunna hantera denna nya marknadssituation måste företagen bli integrerade med varandra inom deras affärsområde. Denna integrering underlättar företagens förmåga att snabbt kunna anpassa sig till nya marknadssituationer och överleva på en snabbt föränderlig marknad. Ett utav de största grundläggande koncepten för denna integrering är flödeshantering (Supply Chain Management). Flödeshanteringen integrerar och koordinerar företagets processer både internt som externt. Informationsteknologi (IT) kan förbättra effektiviteten av flödeshanteringen. IT-lösningar skapar effektivare affärsprocesser och förbättrar integrationen med andra aktörer inom företagets försörjningskedja. Syftet med uppsatsen är att beskriva och förklara effekter för affärsverksamheten samt konsekvenser för dess affärsprocesser, vid en implementering av en realtidslogistiklösning. Uppsatsen syftar vidare till att identifiera framgångsfaktorer vid en sådan implementering. Uppsatsarbetet har genomförts genom en litteraturstudie där teori om flödeshantering, affärsförändring och implementationseffekter har behandlats. En fallstudie i uppsatsen har använts där tre aktörer har blivit intervjuade; en tillverkare (Volvo Powertrain), en underleverantör (Metallfabriken Ljunghäll) och en systemutvecklare (PipeChain). Analysen av litteraturstudien och den empiriska undersökningen har bidragit till en identifiering av huvudeffekter samt konsekvenser vid en implementering av en IT-logistiklösning. Några av dessa effekter är: lagerreducering, högre leveranssäkerhet, förbättrade relationer samt ökad flexibilitet. Exempel på konsekvenser dessa effekter har orsakat är: precisare planering och produktion, effektivare produktionsprocesser samt förbättrad leveransprocess. Vidare så har framgångsfaktorer för lyckad implementering identifierats så som ömsesidig tillit, förståelse för förändring samt utvärdering.

    Higher order mining for monitoring district heating substations2019Ingår 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, artikel-id 8964173Konferensbidrag (Refereegranskat)
    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 Mining2018Ingår i: ACM SIGKDD Workshop On Outlier Detection De-constructed, 2018Konferensbidrag (Refereegranskat)
    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 Sequences2018Ingår i: The 17th IEEE International Conference on Machine Learning and Applications Special Session on Machine Learning Algorithms, Systems and Applications, IEEE, 2018Konferensbidrag (Refereegranskat)
    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.

    Strong L1 convergence to equilibrium without entropy conditions for the Boltzmann equation1999Ingår i: Communications in Partial Differential Equations, ISSN 0360-5302, E-ISSN 1532-4133, Vol. 24, nr 7-8, s. 1501-1535Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The main result of this paper is that for the har dsphere kernel, the solution of the spatially homogenous Boltzmann equation converges strongly in L1 to equilibrium given that the initial data f0 belongs to L1(R3,(1+v^2)dv). This was previously known to be true with the additional assumption that f0logf0 belonged to L1(R3), which corresponds to bounded initial entropy.

    Abstract [en]

    This study examines how students without formal statistics draw conclusions based on statistical data. The study refers to how pupil draw conclusions based on existing data, reason within the subject statistics and which aspects pupil may have difficulty in perceiving. To investigate this, the following research question were used: How do Swedish students without formal statistical training express informal statistical inferences? 

      

    This study is based on informal statistical inference which means that how to draw conclusions based on already existing data about what will happen in the next step. To collect data for this study, the data collection method focusgroup interviews with students in year 5 was used. The collected data were compiled, analyzed and compared with previous research. The results showed that students have difficulty drawing conclusions based on the existing data because they do not see it in a larger context.

    Håller utvecklingen: En studie om hur hållbar utveckling undervisas i årskurserna 4-6.2016Självständigt arbete på grundnivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Undervisningen i hållbar utveckling har sedan mitten av 1990-talet använts som en av tre dominerande miljöundervisningstraditioner i skolan. Hållbar utveckling är idag inget eget ämne, men kursplanen för årskurserna 4-6 lyfter fram begreppet i flertalet ämnen samt att området ska ses ur ett ämnesövergripande perspektiv. Då hållbar utveckling ska undervisas under hela grundskolan har litteraturstudien inriktats på hur undervisningen bedrivs i årskurserna 4-6 och vilken betydelse läraren har för elevernas förståelse. Genom en översikt av aktuell forskning har likheter och skillnader funnits mellan en rad olika arbetssätt. Studien har främst ett fokus på miljöperspektivet inom hållbar utveckling. Studien visar att det finns flera sätt att arbeta med hållbar utveckling som eventuellt kan ha både för och nackdelar. Simulering via datorspel samt utomhuspedagogik är områden forskarna lyfter fram. Studien tar även upp vilka handlingar som är vanligt förekommande i miljöundervisningen. Slutligen presenterar studien en diskussion där resultatet kopplas till våra tidigare erfarenheter och framtida yrkesroll. Något vi finner intressant i studien är avsaknaden av forskning som vänder sig till årskurserna 4-6.

    Elevers förståelse av likhetstecknet: En studie i årskurs 32016Självständigt arbete på avancerad nivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Studiens syfte är att bilda kunskap om elevers förståelse av likhetstecknet och hur undervisning om likhetstecknet i årskurs 3 kan varieras för att bli så effektiv som möjligt. Syftet ska besvaras genom frågeställningarna: vilka variationsmönster som de studerade eleverna kan möta och vilka kritiska aspekter som elever kan identifiera. Kritiska aspekter är det som elever behöver identifiera för att förstå det som ska läras. Variationsmönster innebär att det som är kritiskt i undervisningen ska varieras för att synliggöras. Studien har sin ansats i variationsteorin, där variationsmönster och kritiska aspekter är centrala begrepp.

    En lektion observerades i årskurs 3 och sex elever valdes ut och intervjuades om likhetstecknet. Resultatet av studien visar att eleverna mötte sex kritiska aspekter i undervisningen. I varje kritisk aspekt mötte eleverna ett eller flera variationsmönster. Studien visar också att alla de intervjuade eleverna har en relationell och instrumentell förståelse av likhetstecknet. Eleverna har förståelse av en kritisk aspekt, som den observerade lektionen inte hade berört, nämligen att alla tal måste ingå i en uppgift för att lösningen ska vara korrekt. Fyra av sex elever har förståelse av den kritiska aspekten att det ska vara ekvivalens i en kedja av likheter. Resultatet visar också att elevernas förståelse av likhetstecknet inte är beroende av att de möter variationsmönster i undervisningen, men att de möter de kritiska aspekterna på något sätt.

    Development of Web-based Health Care Services in Swedish County Councils: Strategies, Usage and Challenges2010Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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 review2015Ingår i: Health Systems, ISSN 2047-6965, E-ISSN 2047-6973, Vol. 4, nr 3, s. 189-203Artikel i tidskrift (Refereegranskat)
    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 Study2013Ingår 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. 316-334Kapitel i bok, del av antologi (Refereegranskat)
    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 enterprises2015Självständigt arbete på avancerad nivå (masterexamen), 30 poäng / 45 hpStudentuppsats (Examensarbete)
    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.

    A FRAMEWORK FOR A SUSTAINABILITY TRANSITION OF TWO ENGINEERING MASTER’S COURSES2023Ingår i: Proceedings of the International CDIO Conference, Norges teknisk-naturvitenskapelige universitet , 2023, s. 67-83Konferensbidrag (Refereegranskat)
    Abstract [en]

    Sustainability, as a concept, is permeating most of today’s human activities, including higher education. The increased importance put on sustainability depends largely on the increased awareness of the huge environmental, social, and economic challenges that humanity is currently facing. As is the case with most complex themes, the route towards the application of appropriate actions starts with enlightenment developed within education, where different engineering programs form important subareas. To address this, CDIO Syllabus 3.0 in general, but optional standard 1 in specific, does now to an even greater extent handle sustainability issues. This paper presents a framework that is built upon several key concepts that are strongly related to education for sustainable development (ESD) at the university level, such as key sustainability concepts (as defined by UNESCO), sustainability development goals (as defined by the United Nations) and constructive alignment (as defined by Biggs and Tang). The framework is applied to two engineering master’s courses where sustainability concepts and development goals are integrated and constructively aligned in the learning outcomes, teaching and learning activities, and assessments. Through the analysis of the two courses concerning sustainability, the framework is shown to provide a means for the analysis of how sustainability is currently incorporated in a course, highlight what possible teaching/learning shortcomings exist, and help identify actions that can be taken to overcome these shortcomings. The objective of the framework is thus to support course managers in the development of appropriate actions related to sustainability.

    Balancing walled garden and open platform approaches for the Internet of Things: A case study of Husqvarna Group2016Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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.

    Prevalence of hookworm infection evaluated with Willis flotation and Formal Ethyl Acetate concentration: A field study in Da Nang, Vietnam2016Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Hookworm infection can cause nausea, stomach pain and anemia, with the most harmful effect being found among women of reproductive age and children. The infection rates is high in poor parts of the world with a high number of infected in Asia. The infection is many times neglected since it rarely causes mortality, however the morbidity can be destructive. In Vietnam the prevalence of hookworm is largely unknown, but there is believed to be a 29-80 % infection rate in the country. Through a field study in Da Nang, Vietnam, the prevalence of hookworm was identified using two methods, Willis flotation and formal ethyl acetate concentration. Any correlation between hookworm infection and individuals’ gender, age and geographic area was evaluated. A total of 101 consecutive selected samples from hospitals and communities in rural and urban parts of the city were obtained from both gender ranging between 1-72 years in age. No quantitative differences were found between the two methods nor any correlation between genders (p-value 0,143). The overall prevalence was 16,8%. The rural part of the city showed a higher infection rate in contrast to the urban districts (p-value 0,001). Individuals in the age group 25-48 showed a higher infection rate in contrast to the other age groups (p-value 0,035).

    Customer Maturity Analysis Tool: A case study in designing a Customer MaturityAnalysis Tool2010Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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)2022Ingår i: 2022 IEEE Wireless Communications and Networking Conference (WCNC), IEEE, 2022, s. 2160-2165Konferensbidrag (Refereegranskat)
    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 transportation2023Ingår i: Journal of Revenue and Pricing Management, ISSN 1476-6930, E-ISSN 1477-657X, Vol. 22, nr 4, s. 266-275Artikel i tidskrift (Refereegranskat)
    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 discovery2017Ingår 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. 174-184Konferensbidrag (Refereegranskat)
    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.

    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) (Övrigt vetenskapligt)
    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 Ontologies2020Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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 Instagram2023Självständigt arbete på grundnivå (kandidatexamen), 180 hpStudentuppsats (Examensarbete)
    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’ needs2014Ingår i: Procedia Technology, E-ISSN 2212-0173, Vol. 16, s. 1256-1264Artikel i tidskrift (Refereegranskat)
    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 Småland2012Självständigt arbete på avancerad nivå (magisterexamen), 40 poäng / 60 hpStudentuppsats (Examensarbete)
    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 Chian2011Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    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 Websites2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    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.

    A new biased estimator for the gamma regression model: Some applications in medical sciences2023Ingår i: Communications in Statistics - Theory and Methods, ISSN 0361-0926, E-ISSN 1532-415X, Vol. 52, nr 11, s. 3612-3632Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Gamma Regression Model (GRM) has a variety of applications in medical sciences and other disciplines. The results of the GRM may be misleading in the presence of multicollinearity. In this article, a new biased estimator called James-Stein estimator is proposed to reduce the impact of correlated regressors for the GRM. The mean squared error (MSE) properties of the proposed estimator are derived and compared with the existing estimators. We conducted a simulation study and employed the MSE and bias evaluation criterion to judge the proposed estimator’s performance. Finally, two medical dataset are considered to show the benefit of the proposed estimator over existing estimators.

    A new Liu-type estimator for the Inverse Gaussian Regression Model2020Ingår i: Journal of Statistical Computation and Simulation, ISSN 0094-9655, E-ISSN 1563-5163, Vol. 90, nr 7, s. 1153-1172Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Inverse Gaussian Regression Model (IGRM) is used when the response variable is positively skewed and follows the inverse Gaussian distribution. In this article, we propose a Liu-type estimator to combat multicollinearity in the IGRM. The variance of the Maximum Likelihood Estimator (MLE) is overstated due to the presence of severe multicollinearity. Moreover, some estimation methods are suggested to estimate the optimal value of the shrinkage parameter. The performance of the proposed estimator is compared with the MLE and some other existing estimators in the sense of mean squared error through Monte Carlo simulation and different real-life applications. Under certain conditions, it is concluded that the proposed estimator is superior to the MLE, ridge, and Liu estimator.

    INTERNET OCH PERSONER MED FUNKTIONSHINDER2009Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    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.

    Patienter med pacemaker och implanterbar defibrillator inom magnetresonanstomografi: En litteraturstudie om risker och säkerhetsaspekter2023Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Antalet undersökningar av magnetresonanstomografi har fördubblats de senaste åren. Detta delvis på grund av att tekniken inte använder joniserande strålning men även för att detaljrika bilder kan framställas. Magnetresonanstomografi betraktades i många år som en kontraindicerad undersökning för patienter med pacemaker eller implanterbar defibrillator. Syftet med detta examensarbete var att studera risker hos patienter med pacemaker och implanterbar defibrillator i samband med MR-undersökningar, samt identifiera säkerhetsaspekter. Studiedesign var en systematisk litteraturöversikt. Det innebär att arbetet utfördes i strukturerade och tydliga steg som innefattade sökning, granskning och sammanställning av litteratur. Litteratur som bedömdes att vara relevant för syftet granskades enligt kvalitetsgranskningsmall. Nio vetenskapliga artiklar inkluderade i resultatet. Olika metoder tillämpades i dessa artiklar för att undersöka och utvärdera uppkomst av möjliga risker men även tillämpning av säkerhetsaspekter för att minimera dessa risker. Resultatet visade att patienter med pacemaker eller implanterbar defibrillator kan genomgå en MR-undersökning med låg risk om säkerhetsaspekter följas.

    Impact of Intrinsic Factors and COVID-19 Pandemic on the Use of Technology2021Konferensbidrag (Refereegranskat)
    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.

    Responses of lichen communities to 18 years of natural and experimental warming2017Ingår i: Annals of Botany, ISSN 0305-7364, E-ISSN 1095-8290, Vol. 120, nr 1, s. 159-170Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and Aims 

    Climate change is expected to have major impacts on high alpine and arctic ecosystems in the future, but empirical data on the impact of long-term warming on lichen diversity and richness are sparse. This study report the effects of 18 years of ambient and experimental warming on lichens and vascular plant cover in two alpine plant communities, a dry heath with sparse canopy cover (54 %) and a mesic meadow with a more developed (67 %) canopy cover, in sub-arctic Sweden.

    Methods 

    The effects of long-term passive experimental warming using open top chambers (OTCs) on lichens and total vascular plant cover, and the impact of plant cover on lichen community parameters, were analysed.

    Key Results 

    Between 1993 and 2013, mean annual temperature increased about 2 °C. Both site and experimental warming had a significant effect on cover, species richness, effective number of species evenness of lichens, and total plant canopy cover. Lichen cover increased in the heath under ambient conditions, and remained more stable under experimental warming. The negative effect on species richness and effective number of species was driven by a decrease in lichens under experimental warming in the meadow. Lichen cover, species richness, effective number of species evenness were negatively correlated with plant canopy cover. There was a significant negative impact on one species and a non-significant tendency of lower abundance of the most common species in response to experimental warming.

    Conclusions 

    The results from the long-term warming study imply that arctic and high alpine lichen communities are likely to be negatively affected by climate change and an increase in plant canopy cover. Both biotic and abiotic factors are thus important for future impacts of climate change on lichens.
