    Verification of a method for measuring Parkinson’s disease related temporal irregularity in spiral drawings2017In: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 17, no 10, article id 2341Article in journal (Refereed)
    Abstract [en]

    Parkinson's disease (PD) is a progressive movement disorder caused by the death of dopamine-producing cells in the midbrain. There is a need for frequent symptom assessment, since the treatment needs to be individualized as the disease progresses. The aim of this paper was to verify and further investigate the clinimetric properties of an entropy-based method for measuring PD-related upper limb temporal irregularities during spiral drawing tasks. More specifically, properties of a temporal irregularity score (TIS) for patients at different stages of PD, and medication time points were investigated. Nineteen PD patients and 22 healthy controls performed repeated spiral drawing tasks on a smartphone. Patients performed the tests before a single levodopa dose and at specific time intervals after the dose was given. Three movement disorder specialists rated videos of the patients based on the unified PD rating scale (UPDRS) and the Dyskinesia scale. Differences in mean TIS between the groups of patients and healthy subjects were assessed. Test-retest reliability of the TIS was measured. The ability of TIS to detect changes from baseline (before medication) to later time points was investigated. Correlations between TIS and clinical rating scores were assessed. The mean TIS was significantly different between healthy subjects and patients in advanced groups (p-value = 0.02). Test-retest reliability of TIS was good with Intra-class Correlation Coefficient of 0.81. When assessing changes in relation to treatment, TIS contained some information to capture changes from Off to On and wearing off effects. However, the correlations between TIS and clinical scores (UPDRS and Dyskinesia) were weak. TIS was able to differentiate spiral drawings drawn by patients in an advanced stage from those drawn by healthy subjects, and TIS had good test-retest reliability. TIS was somewhat responsive to single-dose levodopa treatment. Since TIS is an upper limb high-frequency-based measure, it cannot be detected during clinical assessment.

    Redigeringsprogrammens påverkan på bilden: En jämförelse mellan Avid Media Composer och Adobe Premiere Pro2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen söker att svara på frågeställningen: Uppstår det skillnad i bildkvaliteten på material som komprimerats med redigeringsprogrammet Avid Media Composer till H.264, i jämförelse med material som har komprimerats till H.264 med Adobe Premiere Pro. Baserat på resultat från tidigare jämförelser och personlig erfarenhet är förförståelsen att det kommer finnas en märkbar skillnad men ingen av programmen kommer att överskugga den andra.Metoden som använts är att en undersökning i form av enkät har fyllts i av mediastudenter baserad på deras upplevelser av sex stycken bildexempel från varje redigeringsprogram utifrån fem faktorer som rör bildkvalitet: Kontrast, skärpa, brus, färg och rörelseåtergivning. Djupgående intervjuer har sedan utförts med fem av informanterna. Resultatet på undersökningen visar överlag små skillnader mellan Avid Media Composer och Adobe Premiere Pro. Informanterna upplevde i majoritet att materialet från Avid hade högre bildkvalitet.

    Identify the driving behaviour in a parking lot in terms of distance.2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Parking a vehicle can often lead to frustration, air pollution and congestion due to limited availability of parking spaces. With increasing population density this problem can certainly increase unless addressed. Parking lots occupy large areas of scarce land resource therefore it is necessary to identify the driving behaviour in a parking lot to improve it further. This Paper tries study the driving behaviour in the parking lot and for this endeavours it conducted direct observation in three parking lots and used GPS data that was collected prior to this study by the University of Dalarna.

    To evaluate the driving behaviour in the parking lot direct observation was conducted to obtain overall indices of the parking lot vehicles movement. The parking route taken by the driver was compared with the optimal path to identify the driving behaviour in parking lot in terms of distance. The collected data was evaluated, filtered and analysed to identify the route, the distance and the time the vehicle takes to find a parking space.

    The outcome of the study shows that driving behaviour in the parking lots varies significantly among the parking user where most of the observed vehicles took unnecessary long time to complete their parking. The study shows that 56% of the 430 observed vehicles demonstrated inefficient driving behaviour as they took long driving path rather the than the optimal path. The study trace this behaviour to two factors, first, the absent of parking guidance in the parking lots and the second is the selectivity of the drivers when choosing the parking space.

    The study also shows that the ability of GPS data to identify the driving behaviour in the parking lots varies based on the time interval and the type of the device that is being used. The small the time interval the more accurate the GPS data in detecting the driving behaviour in the parking lots.

    Problemlösning i matematik: En litteraturstudie om svårigheter i problemlösning i matematik för elever i grundskolans tidiga åldrar2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Elevers problemlösningsförmåga uppmärksammas i PISA undersökningar som visar att svenska elever

    inte uppnår goda resultat inom området. Problemlösning är en viktig färdighet som elever behöver i

    och utanför skolan. Problemlösning har förekommit sedan flera decennier tillbaka i skolans kursplan i

    matematik.

    Syftet med den här studien är att få kunskap om svårigheter elever kan ha när de arbetar med

    problemlösning i matematik i grundskolans tidiga skolår och, om så möjligt, vilka orsaker som kan

    påverka dessa svårigheter. Resultaten visar att språkfärdigheter som läsförmåga, förståelseförmåga,

    läsflyt samt det matematiska tänkandet påverkar elevers förmåga att förstå och lösa matematiska

    problem. Likaså är färdigheter i matematiska ord och begrepp samt matematisk text- och talförståelse

    väsentliga. Språk- och problemlösningsfärdigheter främjas av färdigheterna i tänkandet som har sin

    grund i språket. Resultaten visar även att kognitiva faktorer och föräldrars utbildningsnivå är orsaker

    som kan ha en inverkan på elevers förmågor i förståelsen och lösningen av problemlösningsuppgifter.

    Slutsatserna som dras i den här studien är att språkfärdigheter och kognitiva faktorer är de mest

    dominerande i de svårigheter elever kan ha i arbetet med problemlösning. Förståelsen av det

    matematiska problemet utgör den viktigaste delen i problemlösningsprocessen som beskrivs av

    matematikern George Polya och består av en fyra stegs process. Ytterligare en slutsats som dras i

    studien är lärarens roll och undervisningens upplägg som utgör en viktig del i elevers förståelse av

    matematiska problem samt förmågan att lösa dem. Metoden som har använts till den här studien är en

    systematisk litteraturstudie där sökningar på svenska och engelska efter vetenskaplig forskning har

    genomförts i olika databaser.

    An efficient algorithm for the pseudo likelihood estimation of the generalized linear mixed models (GLMM) with correlated random effects2009Report (Other academic)
    Abstract [en]

    This paper presents a two-step pseudo likelihood estimation technique for generalized linear mixed models with correlated random effects. The proposed estimation technique does not require reparametarisation of the model. Multivariate Taylor's approximation has been used to approximate the intractable integrals in the likelihood function of the GLMM. Based on the analytical expression for the estimator of the covariance matrix of the random effects, a condition has been presented as to when such a covariance matrix can be estimated through the estimates of the random effects. An application of the model with a binary response variable has been presented using a real data set on credit defaults from two Swedish banks. Due to the use of two-step estimation technique, proposed algorithm outperforms the conventional pseudo likelihood algorithms in terms of computational time.

    Feasible computation of the generalized linear mixed models with application to credit risk modelling2010Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This thesis deals with developing and testing feasible computational procedures to facilitate the estimation of and carry out the prediction with the generalized linear mixed model (GLMM) with a scope of applying them to large data sets. The work of this thesis is motivated from an issue arising in credit risk modelling. We have access to a huge data set, consisting of about one million observations, on credit history obtained from two major Swedish banks. The principal research interest involved with the data analysis is to model the probability of credit defaults by incorporating the systematic dependencies among the default events. In order to model the dependent credit defaults we adopt the framework of GLMM which is a popular approach to model correlated binary data. However, existing computational procedures for GLMM did not offer us the flexibility to incorporate the desired correlation structure of defaults events. For the feasible estimation of the GLMM we propose two estimation techniques being the fixed effects (FE) approach and the two-step pseudo likelihood approach (2PL). The preciseness of the estimation techniques and their computational advantages are studied by Monte-Carlo simulations and by applying them to the credit risk modelling. Regarding the prediction issue, we show how to apply the likelihood principle to carry out prediction with GLMM. We also provide an R add-in package to facilitate the predictive inference for GLMM.

    Feasible estimation of generalized linear mixed models (GLMM) with weak dependency between groups2010Manuscript (preprint) (Other academic)
    Abstract [en]

    This paper presents a two-step pseudo likelihood estimation technique for generalized linear mixed models with the random effects being correlated between groups. The core idea is to deal with the intractable integrals in the likelihood function by multivariate Taylor's approximation. The accuracy of the estimation technique is assessed in a Monte-Carlo study. An application of it with a binary response variable is presented using a real data set on credit defaults from two Swedish banks. Thanks to the use of two-step estimation technique, the proposed algorithm outperforms conventional pseudo likelihood algorithms in terms of computational time.

    Industry shocks and empirical evidences on defaults comovement2009Report (Other academic)
    Abstract [en]

    It is commonly agreed that the credit defaults are correlated. However, the mechanism of such dependence is not yet fully understood. This paper contributes to the current understanding about the defaults comovement in the following way. Assuming that the industries provides the basis of defaults comovement it provides empirical evidence as to how such comovements can be modeled using correlated industry shocks. Generalized linear mixed model (GLMM) with correlated random effects is used to model the defaults comovement. Empirical evidences are drawn through analyzing individual borrower level credit history data obtained from two major Swedish banks between the period 1994-2000. The results show that the defaults are correlated both within and between industries but not over time (quarters). A discussion has also been presented as to how a GLMM for defaults correlation can be explained.

    Likelihood prediction for generalized linear mixed models under covariate uncertainty2014In: Communications in Statistics - Theory and Methods, ISSN 0361-0926, E-ISSN 1532-415X, Vol. 43, no 2, p. 219-234Article in journal (Refereed)
    Abstract [en]

    This paper presents the techniques of likelihood prediction for the generalized linear mixed models. Methods of likelihood prediction is explained through a series of examples; from a classical one to more complicated ones. The examples show, in simple cases, that the likelihood prediction (LP) coincides with already known best frequentist practice such as the best linear unbiased predictor. The paper outlines a way to deal with the covariate uncertainty while producing predictive inference. Using a Poisson error-in-variable generalized linear model, it has been shown that in complicated cases LP produces better results than already know methods.

    Computionally feasible estimation of the covariance structure in generalized linear mixed models2008In: Journal of Statistical Computation and Simulation, ISSN 0094-9655, E-ISSN 1563-5163, Vol. 78, no 12, p. 1229-1239Article in journal (Refereed)
    Abstract [en]

    In this paper, we discuss how a regression model, with a non-continuous response variable, which allows for dependency between observations, should be estimated when observations are clustered and measurements on the subjects are repeated. The cluster sizes are assumed to be large. We find that the conventional estimation technique suggested by the literature on generalized linear mixed models (GLMM) is slow and sometimes fails due to non-convergence and lack of memory on standard PCs. We suggest to estimate the random effects as fixed effects by generalized linear model and to derive the covariance matrix from these estimates. A simulation study shows that our proposal is feasible in terms of mean-square error and computation time. We recommend that our proposal be implemented in the software of GLMM techniques so that the estimation procedure can switch between the conventional technique and our proposal, depending on the size of the clusters.

    Utvärdering av det arbetsmarknadspolitiska projektet "Volvo Cars och dess underleverantörer"2012Report (Other academic)
    Abstract [sv]

    Denna rapport är en utvärdering av det arbetsmarknadspolitiska projektet "Volvo Cars och dess underleverantörer", som har genomförts av Arbetsförmedlingen i samarbete med Skolverket och Svenska ESF-rådet. Den 5 juni 2009 ansökte Sveriges regering om medel hos den Europeiska globaliseringsfonen (EGF)2 för att kunna erbjuda åtgärder för personer som blivit uppsagda från Volvo Cars AB och dess underleverantörer. Syftet med projektet var att kunna erbjuda de som blivit uppsagda kompetensutveckling, nya yrkeskunskaper och möjlighet att etablera egna företag.

    På operativ nivå drevs projektet i samverkan mellan Arbetsförmedlingen och den kom-munala yrkesvuxenutbildningen ("Yrkesvux"). Yrkesvux i Göteborgs kommun fick i upp-drag av Skolverket att samordna den del av verksamheten som berörde kommunal yr-kesvuxenutbildning. Projektet startade 1 januari 2010 och avslutades 31 maj 2011. Enligt kommissionens beslut fick medel även användas retroaktivt för insatser som hade givits till de uppsagda i form av olika arbetsmarknadsutbildningar, det s.k. snabbspåret, under 2009 innan projektet hade startat.

    Av nästan 5 000 individer i målgruppen som registrerade sig vid Arbetsförmedlingen del-tog knappt en fjärdedel i projektets insatser (exkl. vägledning). Av dessa gick 55 procent i aktiviteter enbart genom Arbetsförmedlingen, 37 procent enbart genom Yrkesvux och åtta procent genom både Arbetsförmedlingen och Yrkesvux. De vanligaste förekommande utbildningsinriktningarna var industri och bygg, fordonsindustri, transport och magasine-ring, omvårdnad och handel.

    Review of the literature on credit risk modeling: development of the past 10 years2010In: Banks and Bank Systems, ISSN 1816-7403, Vol. 5, no 3, p. 43-60Article in journal (Refereed)
    Abstract [en]

    This paper traces the developments of credit risk modeling in the past 10 years. Our work can be divided into two parts: selecting articles and summarizing results. On the one hand, by constructing an ordered logit model on historical Journal of Economic Literature (JEL) codes of articles about credit risk modeling, we sort out articles which are the most related to our topic. The result indicates that the JEL codes have become the standard to classify researches in credit risk modeling. On the other hand, comparing with the classical review Altman and Saunders(1998), we observe some important changes of research methods of credit risk. The main finding is that current focuses on credit risk modeling have moved from static individual-level models to dynamic portfolio models.

    Likelihood estimate of treatment effects under selection bias2013In: Statistics and its Interface, ISSN 1938-7989, E-ISSN 1938-7997, Vol. 6, no 3, p. 349-359Article in journal (Refereed)
    Abstract [en]

    We consider methods for estimating the causal effects of treatment in the situation where the individuals in the treatment and the control group are self selected, i.e., the selection mechanism is not randomized. In this case, a simple comparison of treated and control outcomes will not generally yield valid estimates of casual effect. The propensity score method is frequently used for the evaluation of treatment effect. However, this method is based on some strong assumptions, which are not directly testable. In this paper, we present an alternative modelling approach to draw causal inferences by using a shared random-effect model and the computational algorithm to draw likelihood based inference with such a model. With small numerical studies and a real data analysis, we show that our approach gives not only more efficient estimates but also is less sensitive to model misspecifications, which we consider, than existing methods.

    Fitting conditional and simultaneous autoregressive spatial models in hglm2015In: The R Journal, ISSN 2073-4859, Vol. 7, no 2, p. 5-18Article in journal (Refereed)
    Abstract [en]

    We present a new version (> 2.0) of the hglm package for fitting hierarchical generalized linear models (HGLMs) with spatially correlated random effects. CAR() and SAR() families for conditional and simultaneous autoregressive random effects were implemented. Eigen decomposition of the matrix describing the spatial structure (e.g., the neighborhood matrix) was used to transform the CAR/SAR random effects into an independent, but eteroscedastic, Gaussian random effect. A linear predictor is fitted for the random effect variance to estimate the parameters in the CAR and SAR models. This gives a computationally efficient algorithm for moderately sized problems.

    Abstract [en]

    The rapid development of digital technology together with new business models has

    reached new levels in recent years, which has resulted in the processing of personal data

    both increasing and changing. The problem with this development involves the violation

    of personal integrity to a greater extent. In order to harmonize the processing of personal

    data and to strengthen the protection of personal privacy, the EU has introduced a new

    data protection regulation. The regulation will enter into force on May 25, 2018 and will

    apply in national legislation, which will replace the Swedish Personal Data Act.

    The purpose of the study was to identify what measures a number of organizations have

    taken to comply with the rules of data protection regulations and the challenges that may

    arise in the conversion. The study is limited to consent texts and processing of personal

    data. The study is qualitative and we have, through interviews, taken note of a number of

    organizations' views on challenges and measures regarding formulas of consent texts and

    their personal data processing.

    The conclusion in this study shows that all organizations have problems formulating

    consent texts in an informative way, which is required for adequate data protection.

    Musikens påverkan på film: En studie i musikens påverkan på tittarens tolkning av en karaktär.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med den här uppsatsen är att bidra med en djupare förståelse för hur musik påverkar

    uppfattningen av en karaktär i en film. Uppsatsen jämför resultaten från de som studerar inom

    ämnet musikproduktion med de som studerar inom ämnet bildproduktion på Högskolan

    Dalarna. Den undersökning som har bedrivits var av både kvantitativ och kvalitativ karaktär.

    Deltagarna i undersökningen har fått se en filmsekvens i tre olika versioner. Först utan musik,

    sedan med skräckmusik och avslutningsvis med spänningsmusik. Undersökningen är baserad

    på Johnny Wingstedts teorier om hur vi påverkas av musiken i vår vardag. Beroende på vilken

    musik de fick höra i samband med klippen så påverkades deras uppfattning av både

    karaktären samt handlingen i filmen.

    Användning av IKT i matematikundervisning: En intervjustudie med matematiklärare 7-92017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens syfte är att undersöka de IKT med fokus på digitala verktyg som lärare använder i matematikundervisning idag och vilka mål de har med att integrera digitala verktyg. I studien presenteras olika digitala verktyg som används i matematikundervisning, följt av en kort analys.

    Studiens genomfördes genom intervjuer med åtta lärare som undervisar matematik för elever (7-9) och gymnasiet (kurser i grundnivå (7-9)/introduktionsprogrammet). Intervjuerna skedde genom träff (muntliga intervjuer) eller genom mejl(datorstödda intervjuer).

    Studien lyfter fram lärarens roll i elevens lärande med och utan digitala verktyg. Lärarna som har deltagit i studien har olika erfarenheter, arbetssätt och olika syn på användning av digitala verktyg i matematikundervisning. Vissa lärare tycker att det är värdefullt att integrera digitala verktyg i matematikundervisning och att det kan motivera eleverna samt komplettera det som görs i klassrummet. Matematiklärare som väljer att integrera digitala verktyg i undervisningen gör det för att t.ex. att öka elevernas motivation, skapa ökad måluppfyllelse och underlätta lärarens arbete. Andra visar inte samma intresse för användning av digitala verktyg. De senare anser att matematikundervisning med digitala verktyg inte kan säkerställa elevernas förståelse av ämnets innehåll. Enligt dessa mattelärare är digitala verktyg endast ett komplement till den traditionella undervisningen.

    Kriterier och utvärdering av verktyg för datamigration2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Data migration in migration projects have a big chance of failure caused by underestimating the weight and importance of planning for the migration of data between systems. The most common cause of failure is by having inadequate validation. Therefore, knowing what one should be aware of to minimize the risk of data migration will be of help.

    This includes steps from David Barkaway for data migration projects about how to gather and retain generated knowledge for future projects. This also includes steps of how to perform data migration and avoid common causes of failure.

    Based on the collected theory, interview questions will be written that enables me to create criteria a list of criteria for evaluating tools for data migration.

    In this study I have chosen two different tools to evaluate. I will interview four IT-consultants with experience of data migration to best answer which criteria these tools should fulfill to be of interest for these four IT-consultants.

    These tools are:

    1. SQL-Server Integrated Services: A service from Microsoft within the .Net-environment for datamigration och Business Intelligence.

    2. Talend Open Studio for Data Integration: A product from Talend made in java and is open-source, used for data migration.

    The result shows that Talend fulfills more of the criteria than SSIS does.

    Estimation and interpretation of genetic effects with epistasis using the NOIA model2012In: Quantitative trait loci (QTL): Methods and Protocols / [ed] Scott A. Rifkin, Humana Press, 2012, p. 191-204Chapter in book (Other academic)
    Abstract [en]

    We introduce this communication with a brief outline of the historical landmarks in genetic modeling, especially concerning epistasis. Then, we present methods for the use of genetic modeling in QTL analyses. In particular, we summarize the essential expressions of the natural and orthogonal interactions (NOIA) model of genetic effects. Our motivation for reviewing that theory here is twofold. First, this review presents a digest of the expressions for the application of the NOIA model, which are often mixed with intermediate and additional formulae in the original articles. Second, we make the required theory handy for the reader to relate the genetic concepts to the particular mathematical expressions underlying them. We illustrate those relations by providing graphical interpretations and a diagram summarizing the key features for applying genetic modeling with epistasis in comprehensive QTL analyses. Finally, we briefly review some examples of the application of NOIA to real data and the way it improves the interpretability of the results.

    När kapitalet färgar radiovågorna: Hur reklamfinansieringen avspeglar sig i programinnehållet i kommersiell radio2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den kommersiella radion är beroende av reklamfinansiering för sin överlevnad och det enda sättet att locka till sig annonsörer är att kunna visa att man nåt ut till den breda massan och för att nå ut till den breda massan behövs ett intressant redaktionellt innehåll. Det redaktionella innehållet är en produkt av den branschlogik som råder och ingår i det branschformat som genom kloning och franchising sprider sig inom det rådande radioklimatet. Branschformatet för den kommersiella radion avspeglar sig i bland annat rollbesättning, musiken och sändningstempot, vilka i sin tur bildar det redaktionella innehållet. Det som präglar det redaktionella innehållet är dock alltid det allmänna intresset. Branschformatet sägs även sudda ut den gräns som länge funnits och som upprätthållits av branschen där det redaktionella innehållet ska separeras från reklam. Denna gräns blir mer och mer otydlig då man har börjat hitta vägar runt i form av bland annat sponsring av inslag och tävlingar.

    Att uttrycka matematik: En observationsstudie av vilka uttrycksformer och matematiska aktiviteter som uppmuntras och används i förskolan2013Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att fördjupa kunskaperna om vilka matematiska aktiviteter ochuttrycksformer pedagogerna i förskolan använder sig av i planerade matematikaktiviteter.Utgångspunkt för undersökningen var uttrycksformerna som finns beskrivna i förskolansläroplan samt sex historiskt och kulturellt grundade matematiska aktiviteter.Syftet konkretiseras i följande frågeställningar: Vilka matematiska aktiviteter och vilka uttrycksformer uppmuntras och stöds avpedagogerna i planerade matematikaktiviteter? Vilka likheter och skillnader finns beroende på barnens ålder?För att få svar på dessa frågor genomfördes strukturerade observationer av planeradematematikaktiviteter på tre olika förskoleavdelningar. Barnens åldrar var 1-5 år och varjeavdelning observerades vid ett tillfälle under 45 minuter. Tekniker som användes vidgenomförandet av observationerna var papper, penna, kamera och videokamera.Studiens resultat visar att samtal och rörelse är de vanligast förekommande uttrycksformerna iplanerade matematikaktiviteter. Ingen pedagog använde sig av uttrycksformerna lek/drama ellerdans. Av de matematiska aktiviteterna var lokalisera och mäta de mest förekommande, följt avkonstruera hos de äldsta barnen.En slutsats som kan dras av studien är att det behövs en ökad medvetenhet och kunskap hospedagogerna om hur förskolan kan använda alla de uttrycksformer som beskrivs i Lpfö 98/2010för att stimulera och utveckla barnens matematiklärande.

    Säkerhet i molntjänster: Starka autentiseringsmetoder, federeringslösningar & säkerhetshot mot autentisering i moln2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    "Moln" är ett känt ord använt för att beskriva molntjänster. Begreppet moln uppstod för längesen, och användes bland annat på 70-talet för att representera delar som ingen riktigt förstod sig på. Det är inte bara ordet moln som fortfarande orsakar förvirring, utan även dess flertaliga beskrivningar. Dessa gör det svårt att få grepp om vad molntjänster egentligen innebär. Kraven för molntjänster är flera, men man talar oftast om bred tillgänglighet, konsolidering av resurser, snabb elasticitet och mätbara, självbetjäningstjänster. Implementering av säkerhet är viktig för molntjänster för att kunna skydda dem från säkerhetshot. En vanlig men också viktig säkerhetskontroll är autentisering. Autentisering tillsammans med federationslösningar möjliggör för integration mellan molntjänster som vill dela autentisering.

    Rapporten är strukturerad i olika sektioner, innehållande bakgrund till problem, syften som leder fram till frågeställningar och vald metodik. Den teoretiska biten består av en litteraturstudie om bland annat; säkerhetshot mot autentisering i molnet; skydd mot dessa; autentiseringsmetoder passande för molnet; federationslösningar. I analysen jämför rapporten skillnader och likheter mellan resultat från litteraturstudien och från flera intervjuer. I slutsatsen presenteras svar på frågeställningar och resultat från analysdelen. Integration mellan molntjänsters autentiseringslösning kan lösas av federerade identiteter, som även medför fördelarna användarvänlighet och enklare administration. Att alla identiteter samlas på en och samma plats kan dock bli ett attraktivt mål för attacker. Säkerhetshot mot molntjänster existerar i all högsta grad, dock skiljer de sig inte mycket mot traditionella tjänster. Slutsatsen påvisar att kausalitet fortfarande råder för säkerhet i molntjänster, men att förtroende har blivit ytterligare en förklaringsvariabel.

    Den rörliga bildens komponenter som förstärkning av narrativet i spelfilm: En jämförande studie av en svensk och en amerikansk långfilm2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    En spelfilm berättas med hjälp av ljud och bild. Bilden är en form av kommunikation som likt ett

    vanligt språk är uppbyggt med regler. Dessa regler används för att hjälpa publiken att tolka bilden

    och kallas för berättarkomponenter. Denna uppsats bidrar till en djupare förståelse för tre av dessa

    berättarkomponenter: bildkomposition, bildutsnitt och kamerarörelser. Med hjälp av teorin

    analyseras och jämförs bildspråket i två filmer baserade på samma roman av Stig Larsson. Dessa

    två filmer är producerade i två olika filmkulturer.

    Syftet med denna uppsats var att undersöka hur bilden används för att förstärka narrativet i

    långfilm. Filmerna som har analyserats är The girl with the dragon tattoo som har producerats av

    den amerikanska filmkulturen. Den andra filmen är Män som hatar kvinnor som är producerad av

    den svenska filmkulturen. Resultaten av analyserna har sedan jämförts för att ta reda på om det

    finns någon skillnad i bildspråket mellan kulturerna. Uppsatsen visar att båda filmerna tillämpar

    reglerna på ett liknande sätt men att bildspråket anpassas till hur historien berättas.

    Abstract [en]

    This paper describes how distance educations in developing countries can enhance interactivityby means of information and communication technologies. It is argued that e-learning involvesa shift in the educational structure from traditional transmission of knowledge to interactivecreation of knowledge. Our case studies are two distance educations in Bangladesh and SriLanka that use different technologies for implementing interactivity; Internet and computersin one case and video and mobile phones in the other. The findings are analyzed based onStructuration Theory and we compare the two approaches based on emerging norms andbeliefs. Findings from both cases show the concurrent enactment of both the transmissionand the interactive structure. Whereas peer collaboration and the use of self-assessment toolsmake students take more ownership of their learning, we also found the idea of a classroomwith an instructive teacher to be deeply rooted in the students’ minds.

    Reclaiming the students: coping with social media in 1: 1 schools2014In: Learning, Media & Technology, ISSN 1743-9884, E-ISSN 1743-9892, Vol. 39, p. 37-52Article in journal (Refereed)
    Abstract [en]

    There is a debate about the advantages and disadvantages of using social media in education. Drawing on interviews and surveys with students and teachers in three Swedish schools, this study finds that studentsas well as teachers find much of the students' social media use distractive to learning. We investigate this by means of an interpretative study of students' and teachers' experiences. We find that concerns relate to how social media use makes students less social, how weaker students are more likely to get distracted, how teachers lack strategies for tackling the problem and how the responsibility of the use is delegated to the students. We discuss how the distractive use of social media is made possible as a result of education policies requiring a higher degree of individual work, individual responsibility, and educational choices forstudents. Teachers and school leaders need to jointly reclaim the students and coping strategies for the distractive use are urgently needed.

    Identitetsskapande och lärande via visuella intryck och uttryck i och utanför bildundervisningen2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med den här litteraturstudien är att undersöka vad tidigare forskning säger om ungdomars konstruktion av identitet i samband med de visuella intryck och uttryck som används och tar form i och utanför bildundervisningen. I studien synliggörs visuella intryck och uttryck utanför skolan med fokus på sociala medier och gatukonst och deras inverkan på ungdomars representation och konstruktion av identitet; dessutom synliggörs sambandet mellan bildskapande och identitetsutveckling i bildundervisningen: Vad kommunicerar elever och ungdomar själva via sitt bildskapande? Vilka kopplingar finns det mellan visuella uttryck och identitetsskapande i och utanför bildämnet? Hur kan visuella intryck och uttryck i elevers vardag föras in och användas i bildundervisningen för att främja elevers identitetsutveckling och lärande? Resultatet av studien visar bland annat att visuella uttryck är ett sätt för elever och ungdomar att kommunicera avvikande åsikter och perspektiv gentemot samhälle och sociala mönster, skapandet blir med andra ord ett sätt för elever och ungdomar att ifrågasätta och göra sin röst hörd, vilket i sin tur bidrar till att stärka, konstruera eller utveckla en identitet. Identitetsskapande via visuella uttryck bidrar även till lärande då barn och ungdomar i samband med bildskapande utvecklar sin kommunikativa kompetens, vilket framträder i analysen av tidigare forskning som valts ut i studien. I mångt och mycket visar studien på bildens roll vad gäller att experimentera och pröva olika identiteter, samt varför och vilka typer av visuella intryck och uttryck utanför skolan bör och kan föras in och användas i bildundervisningen för att främja elevers lärande.

    Effektivisering av mjukvaruinstallationer: Genom automatiserad mjukvarudistribution2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Software deployment can be seen as the process where all activities are included to make a software available to users without a manual installation on the user’s computer or other machine. There are several software deployment tools that manage automated installations available to enterprises on the market today.

    The department HVDC at ABB in Ludvika has needs of starting to use a tool for automated installations of software which currently is installed manually and is time consuming. As Microsoft partners ABB wants to see how Microsoft’s tool for software deployment could help for this need. 

    Our study aimed to investigate how the department´s work with installations of software looks like today and to find opportunities for improvement for installations that can’t be automated at this time. The study also includes to develop a general framework for how businesses can proceed when they want to start using a software deployment tool. The framework also includes a designed requirement specification that will be evaluated against Microsoft´s tool.

    To create an idea of how the work in the business looks like today, we have performed surveys and interviews with staff in HVDC. In order to develop a framework, we have used the data collected from the interviews, questionnaires and group interviews conducted to identify requirements and wishes from the staff of a software deployment tool. Literature studies were also conducted to create a theoretical framework to use when developing the framework and the requirement specification. 

    Our studies have resulted in a description of software deployment, opportunities for improvement in the work of software installations and a general framework that describes how businesses can proceed when they are about to start using a software deployment tool. The framework also provides a set of requirements that have used to evaluate Microsoft's tool for software distribution. In our study we have not seen that anyone before have developed a general framework and requirements specification that businesses can use as a basis when to start using a software deployment tool. Our results of the study can cover up this knowledge gap.

    Musikbranschen underifrån: En kvalitativ studie om hur oetablerade artister upplever sin omvärld2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Under 2000-talet har nya tekniska innovationer både förändrat hur musik spelas in,

    distribueras och konsumeras. Därmed har nya möjligheter skapats för Sveriges

    oetablerade artister, samtidigt som utbudet blivit större och svårare att tränga igenom.

    Uppsatsen undersöker vad oetablerade artister har för åsikter om läget idag och

    fokuserar kring tre huvudområden; musikutgivning, artistens egen karriär samt

    musikbranschen i stort. Med djupintervjuer som metod syftar studien till att undersöka

    vilka problem som står i vägen för en artist som försöker etablera sig och nå ut med sin

    musik till en större publik. Studien har visat på att artister nuförtiden mycket enkelt kan

    spela in och ge ut sin musik vilket skapat en direkt länk till allmänheten. Det är dock

    mycket svårt att få den uppmärksammad, varför branschkontakter fortfarande värderas

    högt i artisters ögon. Det finns samtidigt en viss misstro mot den etablerade branschens

    kommersialism men varierar stort beroende på vilken typ av aktör det rör. Genom mer

    kunskap om fler musikrelaterade uppgifter har artisterna däremot självsäkerheten att

    själva kunna välja samarbetspartners utifrån var den egna kompetensen brister.

    Kamerors tekniska specifikationer och dess relevans för en publik2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This BA-thesis investigates if the aspects dynamic range, color reproduction and resolution have any effects on how an audience experiences the quality of video/moving images. Today, with fast evolving technology, camera manufacturers have to keep producing new cameras to keep up with their competitors. This saturates the market and makes it harder for filmmakers not knowledgeable about how a camera works and what’s important. In our experience, filmmakers and camera manufacturers focus more on the technical specifications of cameras than what the production actually needs. To answer our question about the three camera aspects, we have conducted two different kinds of studies. The first one is objective, free of opinions and contains only data on how four different cameras compare with one another. After that, we compare the data from this study with a public survey where we show an audience four movies that might appear exactly the same but are filmed with different cameras, the same cameras as in the objective tests.

    What we discovered is that dynamic range, color reproduction and resolution have little to no effect on how the audience experiences the video/moving images. The aspect that had the most effect on the audience was color, but reproduction accuracy was not the important factor and fell out of the scope of our study.

    A study visit to a vitual company2012In: NGL 2012  Next Generation Learning Conference: Conference proceedings, Falun: Högskolan Dalarna , 2012, p. 69-74Conference paper (Other academic)
    Abstract [en]

    To integrate study visits to different workplaces in higher education implies important benefits for the course quality. The study visit gives the students a better understanding for the real situations they will meet in working life. However for practical and economical reasons is that not always possible. The purpose of this project is to create a virtual company that shall replace the real one for study visits. The goal is to create a realistic picture and that intended use of it can come as close as possible to a real study visit. It is also important to facilitate linking theory and practice. The virtual company is built up by pictures, videos and text. All material is made available on a web page and when entering the students will meet a layout of the company. From that position is it possible to walk around and look at videos from different workstations. Besides that can they also listen to interviews with managers and representatives of staff as well as reading reports concerning productivity and the work environment. The focus of the study visit is work sciences, therefore the material also include some visualized information about work hazards. On the web page there are also a number of tasks for the students to carry out. Until the autumn 2011, 132 students at Dalarna University have visited and produced reports from the virtual company. They were studying in programs for mechanical engineering, production technicians and human resource management. An evaluation among some ten students showed that the study visit to the virtual company is flexible in time and effective, but that students wish to have even more detailed information about the company. Experiences from four years of use in a number of classes show that the concept is worth further development. Furthermore with production of new material the concept is likely to be applicable for other purposes.

    Abstract [en]

    Role-based Access Control is a standardized and well established model in terms of handling access rights. However, the accepted ANSI standard 359-2004 lacks the support of geographically delimiting role authorizations. Information systems handling geographical data together with the increasing use of mobile devices call for a need to discuss such spatial aspects within the context of Role-Based Access Control. This thesis seeks to shed light on the current state of knowledge within the subject area as well as to identify aspects of it that are in need of further development. The theoretical framework conceived by the initial literature review has made the conduction of a systematic literature review possible, and the synthesis and analysis of the data together with the theoretical framework have led to the work’s contributions of knowledge: an overview of the subject where the state-of-the art in the area is presented and a structured list of desirous needs of research and development within the area of study.

    Abstract [en]

    This work is a survey about CGI’s self-developed invoice system called CDI. This invoice system is used by Trafikverket and the foundation of this work is based on a survey that maps out what problems there is with the current user interface in CDI. The work focuses only on the view where the user is performing accounts of invoices.

    The user interface that is used today was developed around 2007 and according to CGI, needs a modernization. The idea over sight is to replace the user interface with a new, updated one that helps the user more than the current user interface.

    The purpose of the report is to investigate what problems that users is experiencing with the current user interface and with the help of two self-developed design-proposals evaluate how to fix these problems.

    This is being performed with the help of a zero-state analysis, that maps the current problems and another analysis that evaluates the design-proposals. Both analysis is made from interviews and is performed with three persons from Trafikverket that work with the invoice system on a daily basis.

    When the evaluation is done there will be a revised version of the earlier design-proposals, this will be the final product of this report. The final product will later be used as a foundation in the work around developing the new user interface for CDI.

    besökare. Jag har använt mig av Lars Svedbergs organisatoriska grundteman (2007) för

    att kunna ta reda på hur Vox Publicums verksamhet är organiserad. Vox Publicum

    arbetar för att skapa en säker miljö utan fördomar för ungdomar med intresse för konst

    och kultur, att ungdomar i en trygg miljö ska kunna utveckla sin konstnärliga sida

    samtidigt att utforska sin egna identitet. Som en av informanterna utrycker sig ”Vox

    Publicum gav hen möjligheten att existera utan krav, att kunna utveckla sina intressen

    såsom musik, att ha en plats där hen också hade möjlighet att utveckla sin egna

    person.”.

    Att engagera personal i digitalisering.: En kvalitativ studie om personalengagemang i digitalisering i ett småföretag.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Digitalization is a hot topic in today’s world. It’s almost a must for businesses to engage in digitalization if they want to keep thriving one the market. A study conducted by Tillväxtanalys, a Swedish management authority, shows that businesses within the Swedish construction sector are less likely to have a high degree of digital maturity and a digitalized business. The study also shows that small businesses in general are falling behind big businesses in regard to digitalization. In a small business in the Swedish construction sector, the management have tried for years to digitalize their analogue business. The problem however, is the fear and resistance to change within the organization.

    The purpose of this thesis report was to identify and describe the factors needed to engage the employees of a small business in a digitalization. Identify which types of change resistance that existed within the organization and to determine the degree of digital maturity.

    This case study was conducted with the use of interviews and a questionnaire which have been answered by the employees at this company. The collected data was then analyzed and compared to previous research. The result of this study shows that there are two types of change resistance within the organization and that there are five important factors to engage employees in digitalization within small business; competence, trust, communication, organization-wide need and vision for the change and finally participation.

    A study of Centralized Network Intrusion Detection System using low end single board computers2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of Intrusion Detection Systems is a normal thing today in bigger companies, butthe solutions that are to be found in market is often too expensive for the smallercompany. Therefore, we saw the need in investigating if there is a more affordablesolution. In this report, we will show that it is possible to use low cost single boardcomputers as part of a bigger centralized Intrusion Detection System. To investigate this,we set up a test system including 2 Raspberry Pi 3 Model B, a cloud server and the use oftwo home networks, one with port mirroring implemented in firmware and the other withdedicated span port. The report will show how we set up the environment and the testingwe have done to prove that this is a working solution.

    För- och nackdelar med mobprogrammering: En fallstudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    I have in this case study evaluated advantages and disadvantages with mob programming, at a IT-company called CGM (CompuGroup Medical LAB AB), in Borlänge, Sweden.

    Mob programming is new way to work with computer code creation or system maintenance. A group of developers works together to solve problems, like computer bugs. Only one person sits at the keyboard at one time. Like an evolution of pair programming.

    I have interviewed a selected number of staffs at CGM.

    What are the pros and cons with mob programming for information systems engineers?

    I have also conducted a test, with university students that study information systems science at Dalarna University. The students tested to solve a problem with mob programming, and then evaluated the test in a questionnaire.
