    Creating Real Imaginary Worlds: Mythopoeic Interaction and Immersion in Digital Games2007Report (Refereed)
    Abstract [en]

    Mythopoeia is a term that refers to the making and renewal of myths. Myth is in itself a complicated concept that delicately balances concepts of truth and fiction. Myth refuses the designations of fact or lie, and instead operates beyond those terms. Rather, myths are metaphors, articulations of that which transcends the human psyche, of a type of knowledge that cannot be explained or contested. Throughout mankind's history, mythmaking, or mythopoeia, has been an important part of the legacy passed on between cultures and civilizations. The creation of narratives that are based on, or within particular mythologies, have the power to affect us and move us, in ways that non-fictional stories cannot, simply because myths are fictional truths. The impact of these kinds of stories can be gauged by examining their longevity and spread. What that tells us is that the way something is told is perhaps even more important than what is told. Currently, mythopoeic digital games not only offer the possibility of reading and hearing about faraway lands and galaxies, but a chance of partaking in the sustaining and making of new myths.



    This dissertation will explore and answer the question: how does the constrained nature of digital games, together with the improvised chaos of make believe, interact with, and benefit from (or become inhibited by) the further constraint of mythology? As new narrative technologies are introduced, they affect how myths are written, sustained and should be interacted with. Furthermore, with new visual media the level of detail has risen exponentially. No longer are myths carried by oral tradition, textual accounts, or even photography. The new myths come superimposed at us with photorealism, 24 photos per second, with full Dolby Digital 5.1 Surround Sound, and with vibrating haptic game controllers for true interactive affect and immersion. Altogether, the combination of mythopoeia and narrative technology becomes a very powerful medium for interactive storytelling of which we are only beginning to grasp the full potential

    The political economy of news value and the commodification of the general intellect2011Conference paper (Other (popular science, discussion, etc.))
    Abstract

    Online, globalized commerce is fundamentally changing the dynamics of physical space and social space, opening up the market outside the enclosed area of focused marketing. Low distribution costs, and the ability to cast off the inherent limitations in stock and selection has become a lesser concern, allowing for digitally virtualized industries to focus on a global audience at a global scale. Today, in 2011, we can see this change transforming the market for online news in the post- industrial society. This transformation constitutes one part of the larger transformation from manual labour to intellectual labour that began in the early 1970s. From the perspective

    of the newspaper industry, many scholars agree that this on- going transformation offers many opportunities that may even enhance the relevance of newspapers. This paper applies Italian neo-Marxist thought, more specifically the concept of immaterial labour, to online news in order to reconceptualise the relationship between news production and consumption. Using these theories, this paper offers a comprehensive way of theorizing the commodification of user-generated content and the role of the consumer in news production and news value. Previous research has emphasized news value from the newspaper organizations perspective as news criteria; this paper instead emphasizes the reader as instrumental in the construction of news value, and furthermore how a social exchange process such as readers attention and user generated content brings about a new kind of immaterial labour. The purpose of this paper is to provide a theoretical framework for critically examining the commodification of online news. Online news commodification is approached as the result of a continuous, emergent reproduction of public discourse where value is determined by the amount of remediation cycles a piece of news is subject to during its lifespan, and how much subsequent public attention is generated. In order to improve understanding how the commodity of attention is constructed and sold, the framework emphasizes the differences between print and online news commodification. The result is a new theoretical framework which outlines a) how the concept of news value has evolved into digital news value; b) what factors dictate online value; c) the role of immaterial labour and user generated content in the production of that value

    Time, perception and altered states of consciousness in "Call of Cthulhu: Dark Corners of the Earth"2007Conference paper (Other (popular science, discussion, etc.))
    Abstract [en]

    Showing transitions between different states of consciousness, using sound and image, is an effective tool for creating a particular kind of narrative immersion. One might argue that conveying the inner state of a protagonist in a novel is purely a matter of skill with words and phrases, whereas with visual, aural and tactile technology at hand, storytelling has become a more intricate process.



    This paper will investigate a game text that illustrates Bergsonian notions of time, movement and affect through the sonic portrayal of altered states of consciousness. The example is Call of Cthulhu: Dark Corners of the Earth (2005), a digital game in the "survival horror" genre that exhibits temporal and spatial anomalies during certain segments of first-person gameplay. What is interesting about this text is that it has a sonic trigger unlocking the transition into the realm of postmodern temporal and spatial flux, and its succeeding connection with the realm of the virtual, or potential. In other words, it shows manifestations of altered states of mind that are brought on by stress. To map out the postmodern and metaphysical conditions under which these transitions occur, the theories regarding time, perception and movement outlined by Henri Bergson in Matter and Memory (1911) are the most useful. His theories have subsequently influenced French theorist Gilles Deleuze is concept of the timeimage. These concepts, together with Brian Massumi's theories on affect in Parables of the Virtual (2002) provide a comprehensive theoretical framework for an expanded Bergsonian philosophy of time, movement and affect

    ERP-system: framgångsfaktorer vid införandet2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    The purpose of this report has been to investigate successfactors when implementing ERP-systems in different companies. The opinion of both the supplier and the customer’s point of view about the successfactors has been explained.

    The empiricalstudy has included five different companies and a total of five persons. I have used a qualitative approach during the different interviews. The material from the interviews was analysed with the qualitative method content analysis.

    The study shows the supplier and the customers both have and have not the same opinion about which successfactors to consider when implementing. There are a few obvious connections between the supplier and the customer’s point of view. They agree about the importance of linking business processes and information to the system in the feasibility study. This will lead to an easier and more rapid implementation phase. They also agree about the importance of educating the personal, both in practical skills of the system and also information of the reactions of change in the organisation. This will lead to a greater engagement from the customer and quicker system acceptance.

    Användarfall ur ett spårbarhetsperspektiv2000Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    I detta arbete har en undersökning genomförts angående hur spårbarhet upprätthålls vid användning av användarfall. Rapporten behandlar spårbarhet och användarfall separat för att belysa viktiga fakta inom båda områdena. Syftet med arbetet var att ta reda på hur olika tillvägagångssätt för att representera användarfall upprätthöll spårbarhet mellan olika krav, och mellan krav och dess ursprung. Informationen inom problemområdet samlades in genom en litteraturstudie. I undersökningen identifierades flera olika typer av spårbarhet, vilka sedan låg till underlag för identifiering av spårbarhet i användarfall. Undersökningen visade också att det finns flera olika sätt att representera användarfall, i allt från naturligt språk till formella diagram. Resultatet av undersökningen visade även att användningen av ett modelleringsspråk som Unified Modeling Language (UML), med inbyggda relationer och namnkonventioner, gjorde att spårbarhet kunde upprätthållas mellan olika krav, och mellan krav och dess ursprung. En begränsad spåbarhet identifierades i samband med att mindre formella representationer av användarfall använts.

    Wrapping XML-Sources to Support Update Awareness2000Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Data warehousing is a generally accepted method of providing corporate decision support. Today, the majority of information in these warehouses originates from sources within a company, although changes often occur from the outside. Companies need to look outside their enterprises for valuable information, increasing their knowledge of customers, suppliers, competitors etc.

    The largest and most frequently accessed information source today is the Web, which holds more and more useful business information. Today, the Web primarily relies on HTML, making mechanical extraction of information a difficult task. In the near future, XML is expected to replace HTML as the language of the Web, bringing more structure and content focus.

    One problem when considering XML-sources in a data warehouse context is their lack of update awareness capabilities, which restricts eligible data warehouse maintenance policies. In this work, we wrap XML-sources in order to provide update awareness capabilities.

    We have implemented a wrapper prototype that provides update awareness capabilities for autonomous XML-sources, especially change awareness, change activeness, and delta awareness. The prototype wrapper complies with recommendations and working drafts proposed by W3C, thereby being compliant with most off-the-shelf XML tools. In particular, change information produced by the wrapper is based on methods defined by the DOM, implying that any DOM-compliant software, including most off-the-shelf XML processing tools, can be used to incorporate identified changes in a source into an older version of it.

    For the delta awareness capability we have investigated the possibility of using change detection algorithms proposed for semi-structured data. We have identified similarities and differences between XML and semi-structured data, which affect delta awareness for XML-sources. As a result of this effort, we propose an algorithm for change detection in XML-sources. We also propose matching criteria for XML-documents, to which the documents have to conform to be subject to change awareness extension.

    Automatic Detection of Hypoperfused Areas in SPECT Brain Scans1998In: IEEE Transactions on Nuclear Science, ISSN 0018-9499, E-ISSN 1558-1578, Vol. 45, no 4, p. 2149-2154Article in journal (Refereed)
    Abstract [en]

    Describes a method for automatic identification of areas with perfusion changes in SPECT brain images. An intersubject registration technique is used to stereotactically register images from a selected control group allowing for reference images to be created by averaging the subjects image data. An individual SPECT brain scan can be brought into registration with the reference image and comparison to the normal reference group can be made by subtracting the two volumes. Furthermore, since the variance in the reference group is known, a z-score image or an image coded in standard deviations, can be computed. The SPECT reference volume is defined in the same coordinate system as a brain atlas, and anatomical labeling of areas of interest is possible. The authors show results from the creation of an average image based on 11 individuals and from its comparison with pathological cases

    Fault Isolation By Manifold Learning1985Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis investigates the possibility of improving black box fault diagnosis by a process called manifold learning, which simply stated is a way of finding patterns in recorded sensor data. The idea is that there is more information in the data than is exploited when using simple classification algorithms such as k-Nearest Neighbor and Support Vector Machines, and that this additional information can be found by using manifold learning methods. To test the idea of using manifold learning, data from two different fault diagnosis scenarios is used: A Scania truck engine and an electrical system called Adapt. Two linear and one non-linear manifold learning methods are used: Principal Component Analysis and Linear Discriminant Analysis (linear) and Laplacian Eigenmaps (non-linear).Some improvements are achieved given certain conditions on the diagnosis scenarios. The improvements for different methods correspond to the systems in which they are achieved in terms of linearity. The positive results for the relatively linear electrical system are achieved mainly by the linear methods Principal Component Analysis and Linear Discriminant Analysis and the positive results for the non-linear Scania system are achieved by the non-linear method Laplacian Eigenmaps.The results for scenarios without these special conditions are not improved however, and it is uncertain wether the improvements in special condition scenarios are due to gained information or to the nature of the cases themselves.

    Supervision of Equipment in O&M Infrastructure2007Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    The COMInf network is the infrastructure part of the operation and management system used for guarding the radio access networks developed by Ericsson. This thesis investigates the Ericsson COMInf network; identifies problems covering both functional as well as security aspects of the network and its current monitoring solution, and also presents a set of requirements and recommendations for a future network surveillance solution. As this thesis shows, the COMInf network today has limited functions regarding both network and security supervision.

    However, implementations of such solutions are possible due to the standardized components used in the network today. To improve the COMInf network, this thesis defines requirements and recommends a network surveillance solution which fulfills these requirements. It is also recommended to update some of the hardware currently in place for the COMInf network.

    Anser kunden att ett WIS kan gör denne vis?: Kundens önskemål om informationsinnehåll i ett webbaserat informationssystem2006Independent thesis Advanced level (degree of Magister), 10 points / 15 hpStudent thesis
    Abstract [en]

    The web has a broad affect on the global economy and can among other things be used for web based information systems (WIS). These systems have grown from being used as a market platform to support all activities in the work of an organisation of today. To survive in a turbulent competitive environment, companies must start to cooperate with their customers instead of just collaborate with them. Can an IT-consultant company use a WIS as a tool for keeping in contact with existing customers to attain this cooperation? A WIS could strengthen the relation between customer and supplier and through that have a possibility to increase the customer use since it can facilitate business processes and imply that services can be offered in a new way. WIS have however been characterized by lack of use and not having the expected effects on the business. The reason for this is that only a technical perspective has been taken when they have been developed and implemented, without consideration to organisational circumstances. When taking these facts into consideration, is it possible that a WIS can increase the customer use in the relation between customer and supplier? How does the customer view a WIS and what requirements would s/he have regarding the information content in such a system?

    The purpose with this thesis is that through a demand analysis during pre-study, congregate possible customer requirements regarding the information content in a potential WIS, with consideration taken to the need of how information is communicated, with the intention of increasing the customer use in the relation between customer and supplier.

    The pre-study took a qualitative form and consisted of deep interviews with ten potential users of a WIS. The system could function as a bridge between them and their ITconsultant company, Sigma. Sigma is the employer of this thesis. The theory that has been set as the base for the thesis can be mirrored against four building stones which can be distinguished in the purpose; information content, information handling, customer relationships and customer use. Except from these, we have also included theory regarding WIS in the aim to clarify this type of system. The study showed that there were customer requirements concerning a WIS, in the primary aim of keeping the contact with Sigma. The most prioritised function was education in the form of manuals to prior systems that Sigma had developed on the behalf of the customers. Project handling was then prioritised, in the form of among other things follow-up on projects and joint handling of documents. The customers also regarded that customer service and reports of defects, together with a vocabulary were good functions to include in a WIS. The customers considered that the handling of information could be more structured if a WIS was implemented, but most of them thought that their relation to Sigma would stay unchanged. The customer use with a WIS was regarded to principally be easier access to information for both customer and Sigma, current information and better support together with better service from Sigma.

    A-type Potassium Channels in Dendritic Integration: Role in Epileptogenesis2009Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    During cognitive tasks, synchronicity of neural activity varies and is correlated with performance. However, there may be an upper limit to normal synchronised activity – specifically, epileptogenic activity is characterized byexcess spiking at high synchronicity. An epileptic seizure has a complicated course of events and I therefore focused on the synchronised activity preceding a seizure (fast ripples). These high frequency oscillations (200–1000 Hz) have been identified as possible signature markers of epileptogenic activity and may be involved in generating seizures. Moreover, a range of ionic currents have been suggested to be involved in distinct aspects of epileptogenesis. Based on pharmacological and genetic studies, potassium currents have been implicated, in particular the transient A–type potassium channel (KA). Our first objective was to investigate if KA could suppress synchronized input while minimally affecting desynchronised input. The second objective was to investigate if KA could suppress fast ripple activity. To study this I use a detailed compartmental model of a hippocampal CA1 pyramidal cell. The ion channels were described by Hodgkin–Huxley dynamics.

    The result showed that KA selectively could suppress highly synchronized input. I further used two models of fast ripple input and both models showed a strong reduction in the cellular spiking activity when KA was present. In an ongoing in vitro brain slice experiment our prediction from the simulations is being tested. Preliminary results show that the cellular response was reduced by 30 % for synchronised input, thus confirming our theoretical predictions. By suppressing fast ripples KA may prevent the highly synchronised spiking activity to spread and thereby preventing the seizure. Many antiepileptic drugs down regulate cell excitability by targeting sodium channels or GABA–receptors. These antiepileptic drugs affect the cell during normal brain activity thereby causing significant side effects. KA mainly suppresses the spiking activity when the cell is exposed to abnormally high synchronised input. An enhancement in the KA current might therefore be beneficial in reducing seizures while not affecting normal brain activity.

    Micropayments through cryptocurrency mining2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The monetary policies of states and systems built upon them do not naturally allow transactions of a very small value, as the transaction costs exceeds the actual value of the transaction. These types of transactions are called micropayments. This is problematic as it removes the possibility to monetize content that has a valuation that is so low that the costs of the transaction exceeds the value of the content.

    In this thesis we aim to create a system that allows micropayments to monetize low value content. We do so by developing a design theory based on Gregor and Jones conceptual model for design theories within Information Systems research. The system that we develop will use the end users computational power to generate a value, by running a cryptocurrency miner.

    We present the background knowledge required to fully understand the presented design theory. Within the design theory, we present a theoretical framework to base systems on that enables micropayments through cryptocurrency mining. We also present a developed proof of work prototype that proves the validity of the theoretical framework.

    Lastly we discuss our design theory. We conclude that the design theory enables transactions of a very low value, such as 0,0001 \$ cents. Transactions of such small value is not possible with systems built upon states monetary policies. We also conclude that the proposed design theory can be further developed to function independently of cryptocurrency mining. Instead the value for the transaction could be generated through solving complicated problems if institutions are willing to pay for computational power to solve them.

    Organisering av informationsflödet i kommunsamordningscentralen (KSC): En studie kring informationsflödet mellan fyra kommuner i Skaraborg och ledningen i kommunsamordningscentralen2016Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Denna studie har undersökt hur informationsflödet ska organiseras vid en samverkan mellan kommunsamordningscentralen (KSC) samt de tekniska förvaltningarna i fyra kommuner i Skaraborg.Undersökningen har tillämpat en kvalitativ metodansats för att kunna besvara frågeställningen. Datainsamlingen skedde via semi-strukturerade intervjuer, en litteratursökning efter relevanta artiklar och böcker, samt en djupgående fallstudie.För att skildra teoretiska perspektiv i studien tillämpas även front-office back-office modellen, som indikerar på hur verksamhetens enheter är organiserade. Detta har varit relevant och återkommande i flera faser under arbetets gång. Vidare har även framgångsfaktorer inom business intelligence (BI) behandlats, för att kunna förtydliga hur organisationer ska ha möjlighet att anpassa sig till omvärldens ständiga krav.Uppsatsen har redogjort för vilka aspekter som bör beaktas i samband med en integrering av olika aktörer. Forskning har visat att informationsflödet i de berörda verksamheterna är ineffektivt i dagsläget. Relevansen av detta baseras på att personalen vill tillämpa tydligare tillvägagångssätt för informationshanteringen i kris samt vardagliga situationer. De prioriterar en hög integrering som syftar i att ha ständig kontakt mellan kommunerna och KSC. Däremot är de negativt inställda till en standardisering i informationsflödet vid de vardagliga situationerna, då deras arbetsuppgifter är varierande. Inom krissituationer krävs däremot standarder att följa för tillämpning av interaktionen.Upplägget för denna studie var att, i samband med business intelligence (BI), belysa behov av informationshantering för verksamheter som har en vision för en samverkan.

    Towards A Method for Developing Reference Enterprise Architectures2017In: Tagungsband Wirtschafts Informatik 2017: 13. Internationale Tagung Wirtschaftsinformatik "Towards Thought Leadership In Digital Transformation" / [ed] Jan Marco Leimeister & Walter Brenner, Universität St.Gallen, 2017Conference paper (Refereed)
    Abstract [en]

    In most economic sectors organizations face rapid environmental changes like regulations. Such changes can force them to adjust both their organizational and operational structure. For instance, in the energy utility sector numerous developments moved German Public Utilities (PUs) towards a liberalized market. Nowadays PUs have to stay competitive while managing a heterogeneous information technology (IT) landscape. We address this demand for aligning business and IT by combining the holistic perspective of Enterprise Architecture Management (EAM) with the characteristic of reference modeling to reuse knowledge in a problem domain. Therefore, we utilize configurative reference modeling within Design Science Research (DSR). The artefact at hand is a method for developing a Reference Enterprise Architecture (R-EA), which is applied in the problem domain of PUs. Our contributions are the (i) adaptation of Configurative Reference Modelling (CRM) to develop a R-EA and (ii) a procedure how to elicit knowledge for R-EA development method.

    Implementing a system of Customer Relationship Management: Recurring issues and necessary perspectives of the implementation phase2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the mid 90’s, systems of customer relationship management (CRM) spread like wildfire across the globe and there have been a continuous discussion of what features that should be included and how much technology that should be involved. This discussion has led to different perspectives of how to utilize the systems full potential in the most efficient way and ultimately, a vast variety of different systems of CRM have been created. The challenge is no longer to create, but to implement the system to the organization with low risks and without resistance from the employees. Through a literature study, this thesis will try to identify the most recurrent issues within the implementation-phase and through a few interviews confirm that the recurring problems still exist. Due to its vast variety and the time limit of this thesis, the main focus will be to identify the most recurrent issues but not solve them.

    En jämförelse mellan två öppna ramverk för objektigenkänning: En undersökning gällande noggrannhet och tidsåtgång vidträning och test2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The research in this thesis is conducted with the partners aim to construct a new train detection system that uses image recognition and artificial intelligence. Detectors like these that exists today are expensive, so the construction is going to be based around the use of consumer electronics to lower the cost and simplify installation and maintenance. Several frameworks for object detection are available, but they use different approaches and methods. This thesis is therefore carried out as a case study that compares two widely used frameworks for image recognition tasks. The purpose is to identify advantages and disadvantages regarding training and testing when using these frameworks. Also highlighted is different challenges encountered in the process. The summary of the results is used to form ideas and a discussion about how to implement a framework in the new detection system. The frameworks compared in this study are OpenCV and Google TensorFlow. These frameworks use different methods for object detection, mainly cascade classifiers and convolutional neural nets. The frameworks were tested using a dataset of 400 images on different trains where the wheel-axles were used as the object of interest. The results were analyzed based on criteria regarding precision, total training time and also complexity regarding configuration and usage. The results showed that OpenCV had a faster training process but had low precision and more complex configuration. TensorFlow had a much longer training process but had better precision and less complex configuration. The conclusion of the study is that TensorFlow overall showed the best result and has a better potential for implementation in the new detection system. This is based on the results from the study, but also that the framework is developed with a more modern approach using convolutional neural nets for bject detection.

    There’s More to Movement than Meets the Eye: perspectives on Physical Interaction2010Licentiate thesis, monograph (Other academic)
    Abstract [en]

    In this monograph the use of physical movements in the human-computer interaction situation is treated historically, theoretically and empirically. Current technology enables use of a broad variety of movements in interaction, which here has been studied in designing activities for and with elderly people. That experience is put into context of theories of bodily movement, and participatory design.

    A theme is to visualize perspectives on physical movements in the human computer interaction situation and to point out possible synergies for the design of interactive system from the domains of HCI (Human-Computer Interaction), Interaction Design and Human Factors/Ergonomics.

    With the thesis I want to add to the motivation to ensure that physical movements, and the way we physically can use our bodies, is incorporated as material in design and as a parameter in evaluation of interactive systems.

    My interest in this field derives from my background as practitioner in physiotherapy and expert in physical ergonomics during eight years and from ten years of design experience from research projects within the HCI domain. This background, with one leg from physiotherapy and ergonomics and the other in the HCI research domain, influences my perspective.

    The motivation for this work is that movements are central for human well-being in many situations and over time. We, as human beings, move. The way we seem to get opportunities to move differs in different stages of age.

    In the two projects described the theme has been to observe, analyse and reflect on the way bodily movements can be involved in and enhance interaction with computers in social situations. I have looked at the reaction and changed situation for elderly at caring institutions when introducing technology that encourages bodily movements. This includes analysis of bodily movements and participatory design with the elderly.

    My main study is about what will happen if elderly living at Special Housing for dementia or outer elderly patients coming for rehabilitation are given access to physical action gaming. The resulting outcome was way over our expectations. They surprised us all! So much of forceful, vivid and focused movements were hidden in the old gamers bodies when motivated to take action and enjoy.

    Hur arbetet med kunder kan standardiseras och förbättras hos ett företag i den medicintekniska branschen2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I dagens samhälle befinner sig alla företag i en mycket konkurrensutsatt miljö, detta har

    medfört att kundfokus ökat i alla företag som vill överleva på marknaden. För att bli mer

    effektiva och få en helhetsbild över det värdeskapande flödet har företag börjat skapa

    processorienterade verksamheter. Med en processorienterad verksamhet ligger fokus på

    slutkunden, dennes krav, behov och önskemål. Med detta fokus aktualiseras behovet av att

    förstå att alla kunder är inte viktiga kunder och behovet av kategorisering skapas för att

    kunna differentiera kundservice av olika slag.

    Många företag idag har problem med sin kundhantering, så även fallföretaget Getinge

    Sverige AB. De har ingen gemensam bild av vad en kund är och inte heller några

    standardiserade processer för hur arbetet med kunder skall se ut.

    Det övergripande syftet med uppsatsen är att visa på hur standardiserade processer kring

    kunderna skall kunna skapas samt hur kriterier för en bra kundkategorisering kan tas fram.

    För att illustrera detta kommer arbetet att utföras på ett fallföretag, Getinge Sverige AB.

    Arbetet skall ge dem ett förslag på en gemensam bild av vad en kund är samt skapa

    standardiserade processer för hur arbetet med kunder skall se ut. Jag skall också ge förslag

    på hur en bra kundkategorisering skulle kunna skapas.

    Genom intervjuer med personer på olika positioner inom Getinge Sverige AB har den

    aktuella empirin samlats in. Den empiriska informationen har sedan analyserats med hjälp

    av litteratur från den teoretiska referensramen.

    Arbetet resulterade i att ett flertal brister identifierades, både i arbetssätt och i synsätt. De

    största bristerna var att de inte har någon gemensam bild av vad en kund är och de inte

    använder sig av affärssystemet Movex i den utsträckning det är tänkt att användas.

    Slutsatserna av arbetet blev att definitionen av vad en kund är borde innefatta både

    nuvarande och framtida kunder. Detta för att visa på att företaget vill utvecklas och växa,

    inte bara vara nöjda med nuläget. Vidare skall en bra kundkategorisering bygga på hur

    lönsam en kund är, inte hur mycket denne omsätter. Orsaken är att även om en kund

    omsätter mycket så kan den i gengäld kräva mycket service och dra andra kostnader, detta

    kan i värsta fall kan leda till att det blir en förlustkund. Med andra ord så är inte alla kunder

    som omsätter mycket pengar viktiga kunder. Till sist så bör alla företag använda sig av sitt

    affärssystem i den utsträckning det är möjligt för att stödja sina processer och skapa ett

    standardiserat sätt att arbeta.

    The effect of constructing versus solving virtual patient cases on transfer of learning: a randomized trial2016In: Perspectives on Medical Education, ISSN 2212-277X, Vol. 5, no 1, p. 33-38Article in journal (Refereed)
    Abstract [en]

    The purpose of this study was to explore the effect of actively constructing virtual patient (VP) cases compared with solving VP cases on knowledge gains, skills transfer and time spent on cases. Forty-five fourth-year medical students were randomized to constructing (VP-construction, n = 23) or solving (VP-solving, n  = 22) four cardiopulmonary VP cases. Whereas the VP-solving group solved the cases, the VP-construction group only received the final diagnosis and had to complete the history, physical findings, and lab results. After a week, participants completed a transfer test involving two standardized patients representing cardiopulmonary cases. Performances on the transfer test were video-recorded and assessed by two blinded raters using the Reporter, Interpreter, Manager, Educator (RIME) framework. Thirty-nine participants completed the transfer test. The VP-construction group spent significantly more time on the VP cases compared with the VP-solving group, p = 0.002. There were no significant differences in RIME scores between the VP-construction group and VP-solving group, p = 0.54.

    In conclusion, engaging novice students in active VP case construction may be more time consuming than solving VP cases, without resulting in superior skills transfer.

    Parallel gaming related algorithms for an embedded media processor2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A new type of computing architecture called ePUMA is under development by the ePUMA Research Team at the Department of Electrical Engineering at Linköping University in Linköping. This contains several single instruction multiple data (SIMD) cores, which are called SIMD Units, where up to 64 computations can be done in parallel. The goal with the architecture is to create a low-power chip with good performance for embedded applications. One possible application is video games. In this work we have studied a selected set of video game related algorithms, including a Pseudo-Random Number Generator, Clipping and Rasterization & Fragment Processing, analyzing how well they fit the ePUMA platform.

    An international approach to creative pedagogy and students’ preferences of interactive media2013In: Proceedings of the 12th European Conference on e-Learning – ECEL 2013 / [ed] Mélanie Ciussi, Marc Augier, Reading, UK: Academic Conferences and Publishing International , 2013, p. 479-487Conference paper (Refereed)
    Abstract [en]

    The world population lives within an information society, depicted as an era of “integrated software applications” where the new technology and information technology paradigms are affecting the global environment and the international trend of education (Tapscott and Caston, 1993; Ottestad, 2010). Within this context e-learning is presented by Ottestad (2010) as an emerging pedagogy where teachers’ creativity, competence and professionalism (Liakopolou, 2011; Davies, 2013) as a quality force come together with the new technologies to meet students’ preferences for optional learning resources, to empower students and increase their confidence as well as helping learning, understanding, reinforcing knowledge, stimulating interest, increasing collaboration and motivation (Craft and Jeffrey, 2008; Inglis et al., 2011). Previous studies demonstrated that the generation of learners called “Net generation”, “Millenians”, “Digital natives” or “Web generation” (Tapscott, 1998; Howe and Strauss, 2000; Prensky, 2006; Hartmann, 2003 in: Van den Beemt et al., 2011) uses the interactive media vigorously (Duimel and DeHaan, 2007; Schulmeister, 2008 in: Van den Beemt et al., 2011). This study is an international approach developed across four countries: Wales, Sweden, Russia and Greece. The research conducted a Focus Group based on e-learning resource presentation and Surveys with Questionnaires. The results demonstrated students’ preferences for dynamic presentations, effective animation, comic effects (Kruger, 2004) and interactive media. In order to find different learning styles and preferences, online and paper form Questionnaires for course evaluation and assessment were conducted and compared with teachers’ observations and notes. The study proposed optional as well as additional e-learning resources in order to reinforce student learning and it was based on learning theories such as: the concept of learning and reinforcement, stimulus, remembering and schema which can activate experiences stored in the mind (Skinner, 1930 in Kintsch, 1977; Bartlett, 1995). The results of this research are supporting the cognitive development theory, the role of visual and the practical knowledge theory – know-how of interiorization and exteriorization, being a contribution to knowledge (Vygotsky, 1978; Piaget, 1970; Wadsworth, 1979).

    Threats, Challenges and Emerging Standards in Web Services Security2004Report (Other academic)
    Abstract [en]

    One of the hottest trends today within distributed computing is Web Services. Basically, a Web Service can be described as an XML-based interface that can be used by a client application to invoke a computing service distributed in a network via standard Internet protocols. In order for Web Services to become a ubiquitous technique for program to program communication, however, there need to be a solid framework in place for how Web Services that utilizes the public Internet for transport can be properly protected and secured. As the situation appears today, most services are not publicly exposed but are often deployed inside a corporate, private network. This hampers the vision of Web Services that can be publicly published in directories which potential consumers can search in order to find a suitable service to satisfy their need. This paper describes what the general threats and challenges are in deploying secure Web Services over publicly available and insecure networks, as they are explained in the literature. It then continues to give an overview of some of the more known security standards that are beginning to emerge on the scene.

    Utredning av integrationsaspekter vid Rule Based Engineering (RBE)2002Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Vid produktutveckling inom industriföretag finns idag luckor vad gäller IT-stöd i arbetets olika faser. Införandet av s.k. RBE-system (Rule Based Engineering) är ett steg på vägen mot att försöka fylla dessa luckor. Meningen med ett RBE-system kan sägas vara att ersätta traditionella konstruktionshandböcker med motsvarande konstruktionsanvisningar i digital form. Detta ger möjligheter till automatisering av processer som är tidskrävande, monotona och ofta förekommande, t.ex. olika former av komponentval, dimensioneringsprocesser etc. En av utgångspunkterna vid utvecklingen av RBE-system är att utgå från existerande programvaror. Detta kan ställa stora krav på utvecklarna. En fördel är om det finns en solid grund i form av fakta om vilka attribut hos ett program som är viktiga att ta hänsyn till för att underlätta valet av programvaror som lämpar sig integrationstekniskt för att koppla ihop med andra. Detta arbete syftar till att utreda dessa integrationstekniska aspekter.

    Abstract [en]

    Internet surveillance has recently become a hot topic in the media. It is reported among other things that companies collect information about individuals. The data collected may include information about the user's behavior on the internet such as pages visited, search history, activity on social media and more. But how much of this does a regular user know? The purpose of this study is to investigate how aware individuals are of internet surveillance conducted by companies and the data collection which it is based on. What do the users really know about what is collected, for what purpose, and how it is collected? A study was conducted consisting of interviews and questionnaires that examined how knowledge and education individuals have within the subject. It is also examined whether users are actively trying to counteract this. Thereafter it is discussed what this level of knowledge may depend on and what they are doing to counter data collection. This is linked and compared to previous research in the area.

    Emulation of IP Core Network for Testing of the Serving GRPS Support Node (SGSN) Routing Application2009Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to investigate a method and tool for emulation of the General Packet Radio Service (GPRS) core network needed as an environment to test the routing functionality. GPRS is the most widely adopted mobile packet data delivery technology in the world. It utilizes an Intranet Protocol (IP)-based core network and involves significant changes to the way the Global System for Mobile communications (GSM) air interface is structured. It also forms the basis of the future structure of mobile network transmission and switching.

    The Serving GPRS Support Node (SGSN) is the most fundamental node in GPRS. Ericsson produces and manages an increasing number of SGSN nodes in the world. One of main functionalities of SGSN node is to forward IP packets according to the destination address in the IP header on IP core network.

    In each new release of SGSN, or when implementation or upgrades have been done on routing application on SGSN, design and test engineers at Ericsson need to emulate the IP core network. This must be done with use of many routers to generate huge amounts of data that can simulate the real world IP core network.

    The major goal of this thesis was to analyze and verifying the use of a suitable and economical solution to emulating IP Core Network of the GPRS system for testing of different functionality of the routing application running in SGSN , instead of building up a physical Core Network with different infrastructure and many routers.

    The method chosen for emulating the IP core network with many routers, and investigated in the thesis, is based on a Cisco simulator called “Dynamips”, which runs many actual Cisco Internetwork Operating Systems (IOS) with many different models of Cisco products in a virtual environment on Windows or Linux platforms. With this simulator, engineers at Ericsson will be able to use this simulator to emulate IP core network easily and efficiently to accomplish system test cases.

    A conclusion of this work is that Dynamips could be used to emulate many complicated IP core network scenarios, with many routers to generate huge amounts of data to simulate the real world IP core network. The emulated system fulfils its purpose for testing of the routing application of SGSN regarding different functionality and characteristics. This is done to ensure and verify that SGSN routing application meets its functional and technical requirements, and also helps to find undiscovered errors as well as helps to ensure that the individual components of routing application on SGSN are working correctly.

    A preliminary empirical test of a culturally-relevant theoretical framework for the study of successful aging2003In: Journal of cross-cultural gerontology, ISSN 0169-3816, Vol. 18, p. 79-100Article in journal (Refereed)
    Abstract [en]

    This article aims to shed preliminary empirical light on the assumptions underpinning a culturally relevant theoretical framework for the study of successful aging. On the basis of the Kluckhohnian theory of cultural variation, this framework suggests that congruence exists between value orientations concerned with man-nature, time, activity, and relationships, and the manner in which the construct of successful aging is understood. Methodologically speaking, the research project upon which this article is based started out by adapting and further developing the vignette-based instrument that Kluckhohn and Strodtbeck designed to test the theory of cultural variation. Vignette-based interviews were then conducted with 30 Iranian immigrants to Sweden as a preliminary test of the hypothesis of congruence. The results presented in this article suggest that, as posed in the framework in question, there is a relationship between the value orientations that people prefer and the various understandings of successful aging that they uphold. The results suggest also that there is a variety of ways in which the construct of successful aging can be understood, and that variety encompasses other ways of thinking about successful aging besides the master nature, future, productivity, and individuality-oriented views that characterize the gerontological debate. Although further research is necessary, these preliminary results do infer that this framework might offer a theoretically interesting approach to the study of individual, generational, and cross-cultural understandings of successful aging

    Intressenters behov av en kravspecifikation från utgångspunkten kommunicerbarhet2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    En kravspecifikation kan benämnas som en bro mellan analysfasen och design- och implementationsfasen, vilket innebär att kravspecifikationen är en viktigt kommunikationslänk för en bra slutprodukt. Detta arbete berör kravspecifikationen och de behov analytiker och implementatörer har på en kravspecifikation. Behoven gäller innehåll och presentation av innehåll för att uppnå egenskapen kommunicerbarhet. Kommunicerbarhet är att kravspecifikationen skall fungera som en kommunikationskanal kring produkten mellan intressenter och att den ska vara förståelig för samtliga intressenter.

    Frågeställningen i arbetet har undersökts genom att genomföra en survey med intervjuer. Målgrupp var analytiker och implementatörer på IT-företag som utvecklar administrativa system. Resultatet tyder på att innehållsmässiga krav skiljer sig mellan olika intressenter. Vid skapande av en kravspecifikation bör det bl.a. strävas efter att ha hög sökbarhet och tydlighet. Vidare ska det finnas en beskrivning av systemets funktionalitet, verksamhetsbeskrivning, gränssnittsbeskrivning, icke-funktionella krav. Analytiker har behov verksamhetsnära information och implementatörer har behov av systemets uppbyggnad.

    Hur implementerar företag säkerheten vid utveckling av mobilapplikationer?2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Ett av de områden där utvecklingen idag går som snabbast är IT och de senaste åren har det varit mobilapplikationsutveckling som dominerat. Allt fler skaffar smarta mobiler och antalet applikationer (appar) till dessa ökar konstant. Med en internetuppkoppling finns det idag ytterst få begränsningar för vad du kan göra med en smartphone. I takt med att antalet internetuppkopplade enheter eskalerar, ökar också antalet illasinnade individer vilka ser Internet som sin främsta inkomstkälla.

    I den här kandidatuppsatsen intervjuades företagsrepresentanter angående hur företagen tänker kring implementationen av säkerhet vid utveckling av mobilapplikationer. Studien bygger på en empirisk såväl som en teoretisk del.

    Det som framkommit under arbetet med uppsatsen är bland annat att företagen är väl medvetna om säkerhetsriskerna. De gör ingen större skillnad på utvecklingen av traditionella skrivbordsapplikationer och mobilapplikationer. Det är heller ingen stor skillnad mellan dessa säkerhetsmässigt.

    Geografiskt Informationssystem Anpassat För Mobiltelefoner2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Denna rapport beskriver framtagande av ett koncept för ett geografiskt informationssystem som är anpassat för att köra på moderna mobila enheter ute i fält. Detta sätter krav på systemet vad gäller beräkningskraft, lagringsutrymme samt möjligheten att klara av intermittent datakommunikation. För att ta fram systemet utfördes först en förstudie med databaser och sökmotorer användes för att hitta relevant information och relevanta artiklar som kunde hjälpa till vid framtagningen av systemet. Denna fakta tillsammans med utförda tester och ”trial-and-error”-programmering ledde i slutändan till ett koncept som klarade av de krav som ställdes på systemet. ,  Det framtagna systemet består av tre huvuddelar, datalagring, server och klient. Systemet bygger på en kombination av redan färdiga lösningar och nyskapade implementationer. Den viktigaste nyheten är att systemet använder sig av en kombination av så kallade tiles samt rå vektordata. De olika sorternas datatyper används beroende på olika parametrar som kan ställas in på och anpassas på serverdelen.

    Användbarhet hos en fakturatjänst på internet: En användbarhetsstudie som inkluderar en jämförelse mellan användartest och supportärenden2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Hög användbarhet är viktigt på alla produkter men speciellt på onlinetjänster där konkurrensen är stor och tålamodet kort hos användarna. Syftet med uppsatsen är att utvärdera användbarheten på en fakturatjänst på internet genom att granska supportärenden och utföra ett användartest. Arbetet bidrar med förbättringsförslag utifrån funna problem och undersöker huruvida arbete med supportärenden hittar liknande användbarhetsproblem som hittas vid användartest. Supportärenden som kommit in under en fyraveckorsperiod har kategoriserats efter innehåll och ett användartest med åtta deltagare har utförts. Resultatet visar att användbarhetsproblem som identifieras med hjälp av användartest täcker fler typer av problem än problem som identifieras genom supportärenden samt att det finns mer bakomliggande förståelse till varför problemet uppstått när det identifieras via användartest. Användbarheten på tjänsten uppfattas som godkänd av testdeltagarna men 32 förbättringsförslag har förmedlats till utvecklarteamet bakom tjänsten. Exempel på förbättringsförslag är att göra det obligatoriskt för användare att fylla i företagsuppgifter, att systemet genomgående ger mer respons till användarna och att skapa en länk för ”nytt konto” bredvid inloggningsfunktionen.

    An IoT based Intelligent Building Management System for Ambient Assisted Living2015In: 2015 IEEE INTERNATIONAL CONFERENCE ON COMMUNICATION WORKSHOP, IEEE , 2015, p. 246-252Conference paper (Refereed)
    Abstract [en]

    Ambient Assisted Living (AAL) describes an ICT based environment that exposes personalized and context-aware intelligent services, thus creating an appropriate experience to the end user to support independent living and improvement of the everyday quality of life of both healthy elderly and disabled people. The social and economic impact of AAL systems have boosted the research activities that combined with the advantages of enabling technologies such as Wireless Sensor Networks (WSNs) and Internet of Things (IoT) can greatly improve the performance and the efficiency of such systems. Sensors and actuators inside buildings can create an intelligent sensing environments that help gather realtime data for the patients, monitor their vital signs and identify abnormal situations that need medical attention. AAL applications might be life critical and therefore have very strict requirements for their performance with respect to the reliability of the devices, the ability of the system to gather data from heterogeneous devices, the timeliness of the data transfer and their trustworthiness. This work presents the functional architecture of SOrBet (Marie Curie IAPP project) that provides a framework for interconnecting efficiently smart devices, equipping them with intelligence that helps automating many of the everyday activities of the inhabitants. SOrBet is a paradigm shift of traditional AAL systems based on a hybrid architecture, including both distributed and centralized functionalities, extensible, self-organising, robust and secure, built on the concept of "reliability by design", thus being capable of meeting the strict Quality of Service (QoS) requirements of demanding applications such as AAL.

    Framgångsfaktorer för att uppnå önskad anpassningsgrad mellan kundens affärsproceser och affärssystem: En fallstudie av en kund-systemleverantörsrelation2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Företag och organisationer använder idag affärssystem för att organisera inom företaget eller organisationen. Fördelar med affärssystem är integrationen med informationsförsörjning som strömmar genom hela företaget via en central databas, på så sätt ökar även företagets eller organisationens effektivitet. Även om många företag och organisationer betraktar affärssystem som en lösning uppstår det konflikter mellan affärssystemet och företagets eller organisationens affärsprocesser. Oftast leder det till att företag och organisationer står inför två olika val; att förändra affärsprocesserna så att de anpassas till systemet med minimal anpassning eller att ändra systemet så att det anpassas till affärsprocesserna. Det finns ett antal framgångsfaktorer för företag och systemleverantörer att ta hänsyn till för att uppnå en önskad anpassningsgrad mellan kundens affärsprocess och affärssystemet.

     

    Uppsatsen syfte är att identifiera och beskriva framgångsfaktorer för att uppnå önskad anpassningsgrad mellan kundens affärsprocess och affärssystem, ur ett kund- systemleverantörsperspektiv. Metoden för denna uppsats har varit fallstudiemetoden som har baserats på både observationer och intervjuer med två respondenter från respektive fallföretag. Observationer har skett under praktikarbete hos ett affärssystemsleverantörsföretag. För att få ett relationsperspektiv har därför två fallföretag valts ut: en affärssystemsleverantör samt ett kundföretag till affärssystemsleverantören.

     

    De tre viktigaste slutsatserna från studien är att: Affärsprocessens struktureringsgrad styr, Tydliga mål är viktigt och att Kommunikationen är A-O i ett kund−systemleverantörssamarbete. Affärsprocessens struktureringsgrad, hos kunden, i denna studie har styrt ifall affärssystemet har fått anpassa sig efter affärsprocessen eller om affärsprocessen har fått anpassa sig efter affärssystemet. I det fallet att affärsprocessen är strukturerad har affärssystemet fått anpassa sig till affärsprocessen. Om affärsprocessen är ostrukturerad har istället affärsprocessen fått anpassa sig efter affärssystemet. Tydliga mål och Kommunikation är två viktiga framgångsfaktorer vilka var bristfälliga under det studerade införandeprojektet. Detta medförde till att affärssystemet blev mer tillkrånglat i det fallet när affärssystemet fick anpassa sig till den ena affärsprocessen. Detta uppfattas idag ha blivit problematiskt och påverkar både kundföretaget och affärssystemsleverantören negativt.

    Blockchain, the future opportunity for trading progression?2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The rapid expansion of computer technology have forced several business sectors to integrate with the continuous development of techniques in order to assist them in various tasks. Many fields have happily embraced the technology implementing it in numerous ways, however the development speed have proven difficult to keep up with. The insurance industry have struggled with ridding themselves of old and monolithic legacy systems with a haphazard construction. These systems are costly, cumbersome and often reliant on a “third party” centered structure creating such flaws as data leaks and monopolisation.

    Blockchain is a distributed ledger operating over a peer-to-peer basis, with the intention to unshackle contemporary system from their dependence towards central authorities. Additionally, the peer-to-peer architecture introduced a new form of transparency which differs from contemporary solutions used in centralised systems, beyond the peer-to-peer architecture, the blockchain also incorporated consensus algorithms, allowing peers to verify one another to achieve consensus regarding the validity of each block. This resulted in a "trustless system" considering no single party in the community is dependent on the credibility of a central authority.

    In order for the blockchain technology to be applicable on the market it must overcome obstacles such as privacy and the new EU data protection regulation “General protection data regulation”. However a vague definition of personal data have caused ambiguity which appears to be irreconcilable with the blockchain technology. Research have therefore shifted its focus to explore opportunities for the technology to collaborate with techniques from centralisation in order to overcome its obstacles.

    Kampen fortsätter: En studie om kompatibilitetsproblem mellan moderna webbläsare2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    During the 1990’s the two leading web browsers, Internet Explorer and Netscape Navigator, fought each other in a battle for market shares, the so-called browser war. This war caused almost complete incompatibility between the web browsers. Since then, there has been a continual development of common standards for the web. Today conditions for compatibility are a lot better compared to ten years ago, but the problem is not completely solved. The modern web browsers Internet Explorer 6, Firefox 1.5, Opera 8.5 and Safari can display the exact same web page differently despite common standards. The aim of this essay is to investigate the technical causes of the problem and to develop suggested solutions for creating a web page that is fully compatible in modern browsers. The essay contains an extensive literature study, considering definitions, history and problems. The theory was completed with three field interviews with professional web designers. The investigations show that compatibility problems depend on several factors and that it is impossible to create one exhaustive solution that encompasses all problems. However, by combining different techniques one can create a method that covers a large part of both general and specific compatibility problems without colliding with recommended standards.
