    GPU Accelerated Light Field Compression2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis presents a GPU accelerated method to compress light field or light field videos. The implementation is based on an earlier work of a full light field compression framework. The large amount of data storage by capturing light fields is a challenge to compress and we seek to accelerate the encoding part. We compress by projecting each data point onto a set of dictionaries and seek a sparse representation with the least error. An optimized greedy algorithm to suit computations on the GPU is presented. We benefit of the algorithm outline by encoding the data segmentally in parallel for faster computation speed while maintaining the quality. The results shows a significantly faster encoding time compared to the results in the same research field. We conclude that there are further improvements to increase the speed, and thus it is not too far from an interactive compression speed.

    GPU Accelerated Sparse Representation of Light Fields2019In: VISIGRAPP - 14th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications, Prague, Czech Republic, February 25-27, 2019., SCITEPRESS , 2019, Vol. 4, p. 177-182Conference paper (Refereed)
    Abstract [en]

    We present a method for GPU accelerated compression of light fields. The approach is by using a dictionary learning framework for compression of light field images. The large amount of data storage by capturing light fields is a challenge to compress and we seek to accelerate the encoding routine by GPGPU computations. We compress the data by projecting each data point onto a set of trained multi-dimensional dictionaries and seek the most sparse representation with the least error. This is done by a parallelization of the tensor-matrix product computed on the GPU. An optimized greedy algorithm to suit computations on the GPU is also presented. The encoding of the data is done segmentally in parallel for a faster computation speed while maintaining the quality. The results shows an order of magnitude faster encoding time compared to the results in the same research field. We conclude that there are further improvements to increase the speed, and thus it is not too far from an interacti ve compression speed.

    GPU Accelerated SL0 for Multidimensional Signals2021In: 50TH INTERNATIONAL CONFERENCE ON PARALLEL PROCESSING WORKSHOP PROCEEDINGS - ICPP WORKSHOPS 21, ASSOC COMPUTING MACHINERY , 2021, article id 28Conference paper (Refereed)
    Abstract [en]

    In this paper, we propose a novel GPU-based method for highly parallel compressed sensing of n-dimensional (nD) signals based on the smoothed l(0) (SL0) algorithm. We demonstrate the efficiency of our approach by showing several examples of nD tensor reconstructions. Moreover, we also consider the traditional 1D compressed sensing, and compare the results. We show that the multidimensional SL0 algorithm is computationally superior compared to the 1D variant due to the small dictionary sizes per dimension. This allows us to fully utilize the GPU and perform massive batch-wise computations, which is not possible for the 1D compressed sensing using SL0. For our evaluations, we use light field and light field video data sets. We show that we gain more than an order of magnitude speedup for both one-dimensional as well as multidimensional data points compared to a parallel CPU implementation. Finally, we present a theoretical analysis of the SL0 algorithm for nD signals, which generalizes previous work for 1D signals.

    Learning via nonlinear conjugate gradients and depth-varying neural ODEsManuscript (preprint) (Other academic)
    Abstract [en]

    The inverse problem of supervised reconstruction of depth-variable (time-dependent) parameters in a neural ordinary differential equation (NODE) is considered, that means finding the weights of a residual network with time continuous layers. The NODE is treated as an isolated entity describing the full network as opposed to earlier research, which embedded it between pre- and post-appended layers trained by conventional methods. The proposed parameter reconstruction is done for a general first order differential equation by minimizing a cost functional covering a variety of loss functions and penalty terms. A nonlinear conjugate gradient method (NCG) is derived for the minimization. Mathematical properties are stated for the differential equation and the cost functional. The adjoint problem needed is derived together with a sensitivity problem. The sensitivity problem can estimate changes in the network output under perturbation of the trained parameters. To preserve smoothness during the iterations the Sobolev gradient is calculated and incorporated. As a proof-of-concept, numerical results are included for a NODE and two synthetic datasets, and compared with standard gradient approaches (not based on NODEs). The results show that the proposed method works well for deep learning with infinite numbers of layers, and has built-in stability and smoothness.

    PDE-SVD Based Audio Denoising2012In: Proceedings of the 5th International Symposium on Communications Control and Signal Processing (ISCCSP), 2012, Piscataway, NJ, USA: IEEE , 2012, p. 1-6Conference paper (Refereed)
    Abstract [en]

    In this paper we present a new method for denoising audio signals. The method is based on the Singular Value Decomposition (SVD) of the frame matrix representing the signal inthe Overlap Add decomposition. Denoising is performed by modifying both the singular values, using a tapering model, and the singular vectors of the representation, using a nonlinear PDE method. The performance of the method is evaluated and compared with denoising obtained by filtering.

    Scientific Integrity Requires Publishing Rebuttals and Retracting Problematic Papers2023In: STEM CELL REVIEWS AND REPORTS, ISSN 2629-3269, Vol. 19, p. 568-572Article in journal (Refereed)
    Abstract [en]

    Recently, an article by Seneff et al. entitled "Innate immunosuppression by SARS-CoV-2 mRNA vaccinations: The role of G-quadruplexes, exosomes, and MicroRNAs" was published in Food and Chemical Toxicology (FCT). Here, we describe why this article, which contains unsubstantiated claims and misunderstandings such as "billions of lives are potentially at risk" with COVID-19 mRNA vaccines, is problematic and should be retracted. We report here our request to the editor of FCT to have our rebuttal published, unfortunately rejected after three rounds of reviewing. Fighting the spread of false information requires enormous effort while receiving little or no credit for this necessary work, which often even ends up being threatened. This need for more scientific integrity is at the heart of our advocacy, and we call for large support, especially from editors and publishers, to fight more effectively against deadly disinformation.

    Visualization of cyber security attacks2020Independent thesis Advanced level (degree of Master (Two Years)), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    The Swedish Defence Research Agency (FOI) simulates cyber attacks for research and education purposes in their cyber range, CRATE, with a system called SVED. This thesis describes the process of creating a visualization of the log files produced by SVED, with the purpose of increasing the users’ comprehension of the log files and thereby increasing their knowledge of the simulated attacks.

    To create an effective visualization a user study was held to know the users’ needs, experiences and requirements. Several designs were created based on the results and one was selected and refined using feedback from workshops. A web-based implementation of the design was created using the D3.js library, which included a directed graph, icicle chart and network graph to visualize the data. Thereafter an evaluation was held to analyze if the implementation was more effective than the log files, by letting the participants solve tasks defined by the user study.

    The results from the evaluation indicates that the visualization has a higher success rate than the log files when solving the tasks. They also indicate that finding the solution requires less time with the visualization. However, since the evaluation tasks were based on the user study, the results only conclude that the visualization is more effective when solving similar tasks.

    For further development the visualization could be improved with features like real time rendering and linkage with FOI’s internal systems. Additionally, with more research and further testing, the visualization could be used as a tool for standardization of graphics in cyber space.

    In conclusion, a visualization of the log files has been implemented and according to the evaluation does the visualization increase the users’ comprehension of the data in SVED’s log files.

    Evolutionary Pathlines for Blood Flow Exploration in Cerebral Aneurysms2019In: Eurographics Workshop on Visual Computing for Biology and Medicine / [ed] Kozlíková, Barbora and Linsen, Lars and Vázquez, Pere-Pau and Lawonn, Kai and Raidou, Renata Georgia, The Eurographics Association , 2019Conference paper (Refereed)
    Abstract [en]

    Blood flow simulations play an important role for the understanding of vascular diseases, such as aneurysms. However, analysis of the resulting flow patterns, especially comparisons across patient groups, are challenging. Typically, the hemodynamic analysis relies on trial and error inspection of the flow data based on pathline visualizations and surface renderings. Visualizing too many pathlines at once may obstruct interesting features, e.g., embedded vortices, whereas with too little pathlines, particularities such as flow characteristics in aneurysm blebs might be missed. While filtering and clustering techniques support this task, they require the pre-computation of pathlines densely sampled in the space-time domain. Not only does this become prohibitively expensive for large patient groups, but the results often suffer from undersampling artifacts. In this work, we propose the usage of evolutionary algorithms to reduce the overhead of computing pathlines that do not contribute to the analysis, while simultaneously reducing the undersampling artifacts. Integrated in an interactive framework, it efficiently supports the evaluation of hemodynamics for clinical research and treatment planning in case of cerebral aneurysms. The specification of general optimization criteria for entire patient groups allows the blood flow data to be batch-processed. We present clinical cases to demonstrate the benefits of our approach especially in presence of aneurysm blebs. Furthermore, we conducted an evaluation with four expert neuroradiologists. As a result, we report advantages of our method for treatment planning to underpin its clinical potential.

    Att sätta ett varumärke i rörelse genom att animera en logotyp2018Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Denna studie syftar att undersöka hur en svensk inkubators statiska logotyp skulle kunna animeras utifrån dess varumärkes värdeord; inspirerande, inkluderande och utvecklande. Dessutom syftar den att identifiera hur en animation av en logotyp påverkar tolkningen av en verksamhets varumärke. Genom att använda sig av metoden forskning genom design har en animerad logotyp tagits fram åt verksamheten East Sweden Game. En förstudie utfördes för att få grepp om verksamheten och därefter följde en designprocess i fem steg. Först identifierades ytterligare information om verksamheten för att sedan skissa koncept i storyboards. Därefter animerades de mest lovande koncepten till utkast som efteråt värderades av East Sweden Game och Fishy Minds. Efter värderingen färdigställdes de två mest lovande animationerna och validerades genom en kvantitativ studie samt en kompletterande kvalitativ studie. Resultaten från studierna visade att ett av förslagen, “Kontrollen” som kan ses nedan, utmärkte sig och ansågs av respondenterna representera värdeorden och verksamheten bättre. Båda animationerna ansågs också av en majoritet tillföra något positivt för East Sweden Games varumärke.

    Even sexier: How visual communication can be designed to encourage testing for STDs2023Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Könssjukdomar är ett ständigt aktuellt ämne, som särskilt drabbar unga vuxna. Det faktum att könssjukdomar kan smitta och ha långsiktiga konsekvenser även när de är asymptomatiska gör det viktigt att som sexuellt aktiv testa sig – ändå är det många unga vuxna som sällan eller aldrig gör det. Det här arbetet syftar till att undersöka hur visuell kommunikation kan utformas för att uppmuntra unga vuxna att testa sig vid varje ny sexuell partner. Genom relevant teori i samband med en förstudie bestående av en enkätundersökning, semistrukturerade intervjuer och en analys av existerande visuell kommunikation kring sexuell hälsa har en möjlig lösning på problemet kunnat formulerats, i form av en grafisk kampanj bestående av tre annonser. Kampanjen visar på hur visuell kommunikation kring könssjukdomar kan se ut, och slutsatserna som dras är att visuell kommunikation kring det här ämnet med fördel kan utformas på ett ungdomligt, avstigmatiserande och fängslande sätt.

    Image enhancement of license plates in images using Super Resolution2015Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Bildgruppen på enheten för dokument och informationsteknik hos SKL har ett behov av att kunna förbättra bilder med extremt låg upplösning. Detta bildmaterial kan komma från diverse övervakningskameror där det intressanta objektet endast utgör en väldigt liten del, i detta fall registreringsskyltar på förbipasserande bilar. Att skapa en högupplöst bild av en registreringsskylt utav ett fåtal lågupplösta bilder är ett välkänt problem med ett flertal förslag på metoder och lösningar. I denna rapport kommer vi att undersöka vilka metoder som passar bäst vid bildförbättring av registreringsskyltar. Vi kommer även att skapa ett användargränssnitt där man kan läsa in en bild och välja mellan att automatiskt hitta registreringsskylten i bilden eller att manuellt klippa ut den. Efter att man erhållit en bild innehållandes endast registreringsskylten ska de olika implementerade bildförbättringsmetoderna kunna användas. Slutligen diskuteras vilka för- och nackdelar de respektive metoderna har. Förslag på eventuella förbättringar och hur man kan utveckla dessa metoder vidare presenteras därtill.

    Implementing an Interactive Simulation Data Pipeline for Space Weather Visualization2018Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis details work carried out by two students working as contractors at the Community Coordinated Modelling Center at Goddard Space Flight Center of the National Aeronautics and Space Administration. The thesis is made possible by and aims to contribute to the OpenSpace project. The first track of the work implemented is the handling of and putting together new data for a visualization of coronal mass ejections in OpenSpace. The new data allows for observation of coronal mass ejections at their origin by the surface of the Sun, whereas previous data visualized them from 30 solar radii out from the Sun and outwards. Previously implemented visualization techniques are used together to visualize different volume data and fieldlines, which together with a synoptic magnetogram of the Sun gives a multi-layered visualization. The second track is an experimental implementation of a generalized and less user involved process for getting new data into OpenSpace, with a priority on volume data as that was a subject of experience. The results show a space weather model visualization, and how one such model can be adapted to fit within the parameters of the OpenSpace project. Additionally, the results show how a GUI connected to a series of background events can form a data pipeline to make complicated space weather models more easily available.

    Use of Thermal Imagery for Robust Moving Object Detection2021Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This work proposes a system that utilizes both infrared and visual imagery to create a more robust object detection and classification system. The system consists of two main parts: a moving object detector and a target classifier. The first stage detects moving objects in visible and infrared spectrum using background subtraction based on Gaussian Mixture Models. Low-level fusion is performed to combine the foreground regions in the respective domain. For the second stage, a Convolutional Neural Network (CNN), pre-trained on the ImageNet dataset is used to classify the detected targets into one of the pre-defined classes; human and vehicle. The performance of the proposed object detector is evaluated using multiple video streams recorded in different areas and under various weather conditions, which form a broad basis for testing the suggested method. The accuracy of the classifier is evaluated from experimentally generated images from the moving object detection stage supplemented with publicly available CIFAR-10 and CIFAR-100 datasets. The low-level fusion method shows to be more effective than using either domain separately in terms of detection results.

    Den lilla butikens användning av Instagram - att skapa tilltalande content2018Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [sv]

    Innehållsmarknadsföring är en metod för att nå ut med sitt varumärke och nå sina kunder med hjälp av innehåll av redaktionell ton. Tidigare studier har gjorts om hur innehållsmarknadsföring kan användas men få har fokuserat på hur små självständiga butiker kan använda sig av detta. Denna studie syftar till att undersöka hur en liten butik kan utforma content som tilltalar sin målgrupp och hur en strategi över skapandet av content i syftet att publicera på Instagram ska utformas. Studien har utgått ifrån caseföretaget No 36. No 36 är en liten självständig butik som är återförsäljare av modevarumärken. Data samlas in via en enkätundersökning och semistrukturerade intervjuer. En designprocess genomförs i syfte att skapa content för publicering på Instagram. En utvärdering av designen sker med hjälp av semistrukturerade intervjuer med representanter med No 36s målgrupp. Studien visar att content som skapas ska vara inspirerande, fotat enligt snapshot-estetik och ska innehålla korta och koncisa bildtexter. En strategi för publicering av content på Instagram ska innehålla en plan för vilket content som ska publiceras, när det ska publiceras och riktlinjer för hur en sammanhängande tonalitet ska skapas.

    Kroppsaktivism i sociala medier: En studie om individers förhållningssätt till ideal i instagramflöden2022Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Posting on social media is a common phenomenon and is something that many young people do on a daily basis. Through this publication, individuals share their daily life as well as their work life and are actively marketing themselves and businesses. Depending on what an individual posts, there are positive or negative consequences, which can also affect how an individual is affected by exposure.This study aims to investigate how the target group's perception of body ideals are influenced by portraying bodies on social media. The materials surveyed are based on how young people comprehend ideals on social media, what they believe to be true, and their opinion on an individual, based on how an individual chose to portray themself on social media. Responsibility for posting on social media is an issue that is gaining more attention after the influx of influencer development. Being able to post freely can be considered a problem and it can affect people exposed to it.Research questions were answered by conducting semi-structured interviews and exploring image analysis, ideology, and cultural theory. This study takes a qualitative approach and was conducted in six semi-structured interviews with young women and men aged 20-34.The first feasibility study was conducted with the help of a questionnaire, which then formed the basis of the work and further influenced the purpose of the study, also helping to shape the interview material.

    Hembo - En mobilapplikation för att underlätta vardagen tillsammans: UI- & UX-design i en mobilapplikation för att underlätta till ett strukturerat och planerat hushåll2021Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    To plan your life and always have a perspective of all its parts can be difficult- not least if you are to do it together with someone you live with. Today there are multiple options available on how to structure and plan your everyday life. Both digital and analog options, like calendars, post-it notes, shopping lists and notes are available. However, a platform bringing all these activities together in a simple way while being shared with the one you are living with is missing. The aim of this research report is therefore to simplify structures and planning around matters such as activities, events, meals, purchases and expenses in everyday life for people who live together by using calendars, reminders, to-do lists, meal planning and a financial overview. This study thus examines how a mobile application can be designed that could simplify matters in everyday life between at least two adults in a household and how it can be designed to be perceived as having a good usability by the target group.  

    The method consisted of four phases: pilot study, concept phase, processing phase and detail phase where the latter three constitute the design process. The methods were theoretically based on the subject. During the process, the mobile application has been developed partly through usability tests that have resulted in an interactive digital prototype. The mobile application is called Hembo. Hembo provides a helping hand for planning and structuring activities in a household. During the design process, the functions of Hembo, its layout and interface, have been tested. It has been concluded that Hembo is perceived to have a good usability and facilitates planning for people living together.

    Terminal Gothenburg North - A posssible dry port?2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Green Cargo driver idag ett antal terminaler i Sverige i syfte att främja transporter på järnväg och ser möjligheter i att utveckla en av sina terminaler i Göteborg, Göteborg Norra, till en så kallad dry port, alltså en intermodal terminal i inlandet. Detta gav upphov till projektet Terminal Göteborg Norra – en möjlig dry port? med målet att undersöka potentialen och omställningarna med att utveckla befintligt kunderbjudande på Göteborg Norra genom att utreda konceptet dry port samt undersöka efterfrågan på marknaden. Syftet med en dry port är att fungera som en förlängning av hamnen och bör enligt forskare erbjuda samma servicetjänster som en hamn, det vill säga förtullning, säker lagring av både lastade och tomma containrar samt underhåll och städning av containrar. En dry port kan ses som ett bra komplement till hamnar som ligger inne i städer och har problem med begränsade utrymmen i hamnområdet och svårt att expandera då ytan inte längre räcker till. Dessutom kan man minska utsläppen av CO2 genom att få mer gods transporterat på järnvägen. Att utveckla Göteborg Norra, som Green Cargo idag driver i egen regi, skulle innebära att befintliga tjänster behöver kompletteras med de tjänster som fullbordar en dry port. Projektet resulterade i en utredning med potentiella intäkter och kostnader som förväntas uppstå vid ett utvecklande av Göteborg Norra till en dry port. Det visade sig att kostnaderna med att utveckla Göteborg Norra till en dry port är fullt möjliga att tjäna in inom den bestämda tidsramen på två år. Trots det så anser projektet att det finns många delar i utvecklandet som talar emot ett fulländat dry port koncept på Göteborg Norra. Då projektet anser att terminalens läge inte är optimalt för en dry port och att det finns begränsade lagringmöjligheter, oklarheter gällande tulltjänster samt att hamnen inte visar något intresse för att utnyttja tjänsten så är det svårt att motivera omställningen till en fulländad dry port. Däremot finns det en del i dry port konceptet som projektet ser positivt till och det skulle innebära att Göteborg Norra tar emot lastade containrar för transport till hamnen. Då projektets marknadsundersökning visade att många speditörer anser att det är problem med långa köer för att hämta och lämna gods i Göteborgs hamn så skulle Green Cargo kunna erbjuda en tjänst där dessa kunder kan åka till Göteborg Norra och lämna eller hämta sitt gods. Detta under förutsättning att Green Cargo kan erbjuda en billigare lösning och att det inte uppstår köer i trafiken runt terminalen. Klarar Green Cargo detta har de ett bra argument som borde locka både speditörer och Göteborgs hamn att nappa på lösningen.

    Creating an Appealing 3D-visualization Tool for Baseboards in the Web Browser2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today a lot of libraries, tools and techniques exist to create visual appealing renders for the web. In this thesis, a prototype for visualizing baseboards in the web browser was developed. The prototype demonstrates how certain libraries and techniques were used in order to achieve a generalized, appealing and realistic visualization of the baseboards in a 3D-visualization. This paper also covers why certain libraries and techniques were used for this prototype. The resulting prototype, use Three.js and takes advantage of PBR, different mapping methods and lighting sources that can be changed during runtime through a GUI. To get results on different aspects, such as the visual appeal, how realistic, and what lighting sources worked best for the prototype, a web-survey was sent out and the results evaluated. The evaluation showed that the usage of PBR, a roughness-metalness workflow, environment mapping, physical correct lighting and a point light solution in Three.js all made a good job in creating an appealing, generalized and realistic visualization tool for the web.

    Gör om, gör rätt: Att designa en användbar app för en befintlig utbildningsplattform2019Independent thesis Basic level (university diploma), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [sv]

    Denna studie undersöker hur en app för en befintlig utbildningsplattform skulle kunna utformas. Utbildningsplattformen i fråga är LiUs egna system, Lisam. Lisam används som ett verktyg för såväl studenter som lärare men har utstått kritik för saker som komplicerad navigation, osammanhängande gränssnitt samt svåråtkomlig och dåligt uppmärksammad information.

    Studien resulterade i en interaktiv prototyp av en Lisam-app. Prototypens användargränssnitt är uppdelat i fyra huvudkategorier: hem, kurser, samarbetsytor och schema. Genom dessa kan användaren läsa universitetsrelaterade nyheter, se viktiga händelser angående sin utbildning, anmäla sig till tentor och seminarier, kommunicera med olika arbetsgrupper, se sitt schema och mycket mer (se bilaga 1. för fullständig prototyp).

    Att skapa musik med videoredigering: En handledning2020Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    There are several ways to create music. Some ways are more unconventional than others, however. One particular method does not require professional audio editing softwares or digital music instruments compatible with computers. Instead, the only thing required, apart from a music instrument, is video recording equipment and video editing software. The purpose of this study is to examine how well people can –using a video tutorial containing speech, graphical elements and real time instructions- learn how to create their own music. A small-scale, initial study was conducted to find people (without any past experience of music creation) willing to take part in a supervised user test. The supposed amount of test subjects was kept at a minimum due to a current covid19-pandemic, as well as the nature of the test itself. Every respondent was enthusiastic about testing the tutorial and its content. Through an iterative design and editing process, a video tutorial was created with the intent to answer the purpose of this study. The video tutorial was shown to every test subject, whereupon they were instructed to edit their own, predetermined, short musical pieces. The results of the quality-based tests show that musical content creation can be taught, given that the tutorial is clear, pedagogical and efficient.

    Minimalistisk läsmagi: Att designa ett minimalistiskt bokomslag till fantasyromanen Harry Potter och De Vises Sten2018Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Syftet med denna studie var att ta fram ett minimalistiskt bokomslag till fantasyromanen HarryPotter och De vises sten av J.K Rowling. Studien riktar sig till målgruppen svenska läsare. Inledningsvis undersöktes teori inom minimalism samt inom framtagning av design till bokomslag, sedan följde en förstudie i form av en trendspaning för att styrka behovet och intresset för studiens syfte. Förstudien tog även fram vilka värdeord som behövde uppfyllas för att omslaget skulle upplevas som tilltalande och unikt av målgruppen. Förstudien följdes av en designprocess som startade med en webbaserad enkät där det togs fram värdeord som behövde uppfyllas för att omslaget skulle upplevas som tilltalande och unikt av målgruppen. Efter detta formgavs fem omslag vilka föreställde motiv tagna från bokens innehåll. De fem bokomslagen togs vidare till en värderingsfas där tre bokomslag valdes ut som mest minimalistiska av en yrkesverksam designer, en expert. Dessa bokomslag värderades sedan av fyra respondenter som ingick i studiens målgrupp. Slutsatsen av studien visar på att de i denna studie använda sätten av minimalistiska designprinciperna upplevdes rikta sig mot en äldre målgrupp vilken respondenterna ansåg vara målgruppen för de senare delarna av de sju böckerna i serien om Harry Potter. Sammanfattningsvis var respondenterna trots detta positivt inställda till minimalistisk design och uttryckte att det kändes kreativt, tilltalande och unikt.

    Humor i marknadsföring2018Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Den här kandidatuppsatsen undersöker vilka effekter humor har i marknadsföring och hur man kan göra för att lyckas med humoristisk marknadsföring samt undvika negativa effekter som “vampyreffekten”​. Den tar även upp vilka utmaningar och möjligheter det medför att använda humor i dagens medielandskap. För att svara på detta har vi använt oss av kvalitativ metod i form av semi-strukturerade intervjuer. Fem intervjuer har gjorts med verksamma personer inom kommunikations- och marknadsföringsbranschen för att samla deras kunskaper och erfarenheter inom området. Våra resultat visar att humor är ett bra verktyg för att väcka uppmärksamhet och bidra till bättre hågkomst av varumärket. För att det ska fungera så behöver humorn ha en anknytning till varumärket samtidigt som humorn ska kunna representera varumärkets värderingar. Det är även viktigt att kommunikationen sker inom målgruppens referensramar. Dagens medielandskap är resultatet av en stor utveckling under de senaste åren, nya möjligheter och utmaningar har dykt upp. Genom delningar och kommentarsfält på sociala medier kan företag få direkt feedback på sin marknadsföring. Risken för att bli ett forum för till exempel diskriminerande marknadsföring har gjort många varumärken försiktigare, samtidigt som de måste vara modigare för att sticka ut ur bruset.

    Automation of a Data Analysis Pipeline for High-content Screening Data2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    High-content screening is a part of the drug discovery pipeline dealing with the identification of substances that affect cells in a desired manner. Biological assays with a large set of compounds are developed and screened and the output is generated with a multidimensional structure. Data analysis is performed manually by an expert with a set of tools and this is considered to be too time consuming and unmanageable when the amount of data grows large. This thesis therefore investigates and proposes a way of automating the data analysis phase through a set of machine learning algorithms. The resulting implementation is a cloud based application that can support the user with the selection of which features that are relevant for further analysis. It also provides techniques for automated processing of the dataset and training of classification models which can be utilised for predicting sample labels. An investigation of the workflow for analysing data was conducted before this thesis. It resulted in a pipeline that maps the different tools and software to what goal they fulfil and which purpose they have for the user. This pipeline was then compared with a similar pipeline but with the implemented application included. This comparison demonstrates clear advantages in contrast to previous methodologies in that the application will provide support to work in a more automated way of performing data analysis.

    Att utforma en kampanj i syfte att attrahera hållbara aktörer2019Independent thesis Basic level (university diploma), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [sv]

    Hållbar kommunikation har blivit ett allt mer vanligt begrepp. Företag tycks dock ha svårt att berätta om sitt hållbarhetsarbete på ett trovärdigt sätt. Alltför många lyfter fram enskilda hållbara handlingar samtidigt som deras övriga arbete lämnar en del att önska. Syftet med detta arbete är därför att undersöka hur företag på ett trovärdigt sätt kan marknadsföra sig som en hållbar aktör och därigenom attrahera kunder med samma syn på hållbarhet. Vidare undersöker vi hur detta kan bidra till att stärka ett företags image.

    Studien har skett genom framtagning och utvärdering av en releasekampanj där en fiktiv kommunikationsbyrå varit avsändare. En förstudie samt kvalitativ metod har används för att besvara studiens syfte. Det slutgilitga konceptet bygger på en flerstegskampanj som återfinns på såväl fysiska som digitala plattformar vid olika tidpunkter i samband med Earth Overshoot Day. Slutligen ska kampanjen generera besök på den landningssida som återfinns på kommunikationbyråns hemsida. Målet är att mottagaren väljer att kontakta byrån vilket leder till sälj.

    Studien visar att avsändaren behöver uppfattas som en trovärdig och kompetent aktör men att kampanjen även behöver engagera mottagaren. Genom att berätta om hållbarhet på ett objektivt sätt stärker avsändaren bilden av sig själv som en trovärdig aktör. För att mottagaren verkligen ska engagera sig behöver kampanjen fortfarande väcka känslor samt leda till en tankeställare. Vidare visar även arbetet att gerillamarknadsföring kan vara ett kostnadseffektivt sätt att uppnå detta på.

    Photometric stereo for eye tracking imagery2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The goal of this work is to examine the possibility of surface reconstruction from the images produced by the Tobii H5 eye tracker. It starts of by examining classic photometric stereo and its limitations under the illuminator configuration of the eye tracker. It then proceeds to investigate two alternative solutions: photometric stereo under the assumption that the albedo is known and a method that uses the images from the eye tracker as a guide to mold a reference model into the users face. In the second method the pose of the reference model is estimated by minimizing a photometric error under the assumption that the face is Lambertian, using particle swarm optimization. The position of the generic 3D model is then used in an attempt to mold its shape into the face of the user using shape-from-shading.

    Rörlig infografik: Ett sätt att sticka ut i flödet2020Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    This study aims to explore how non-profit organizations can use motion infographic in their social media marketing to attract attention and interest to their work. The study has been done in collaboration with the non-profit organization Hand in Hand and practical examples have been developed based on Hand in Hands work. The goal is that the target group of the organization should understand the effect of the work, get to know how they work, feel engaged and/or want to know more. To do so, a concept and design manners have been formed.

    The study began with a preliminary study in three different parts with the aim to get a greater understanding of Hand in Hand as a business and to investigate similar concepts on social media. It also aimed to give an idea of the given target groups view on; Instagram content, non-profit organizations and ways of presenting information. Subsequently, a design process was carried out based on the preliminary studies and previous research. Several concepts were developed and evaluated to find one final concept to continue working on. Thereafter, practical examples of the chosen concept were designed. This included developing a script, a storyboard, design and animation. Evaluation of the final practical examples was done through five semi-structured interviews with a complementary questionnaire.

    The study resulted in a design concept for motion infographic for Hand in Hand. The concept is designed with the target group in mind and to attract attention and arouse interest to the work of non-profit organizations on social media. Through the use of illustrated graphics and motion elements, attention can be captured since its usage is relatively new on social media and makes it stand out in the feed. The concept arouses interest through the use of continuous movement and the creation of a story, which makes the viewer want to know more.

    Anomaly detection on factory lathe using audio analysis and deep learning2019Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper presents a master’s thesis project in which a system for anomaly detection on sound of a factory lathe has been developed and evaluated. The audio has been recorded with a microphone on site and has been analyzed using Fourier transforms and a Gated Recurrent Unit, developed to detect when this machine is running. An autoencoder has been used to determine if the gathered audio contains anomalies and thus indicates an error with the machine.

    The Gated Recurrent Unit has been evaluated using the metrics Precision, Recall and F1 score along with ROC curves and AUC, which has been used for comparison. To test the autoencoder, artificial anomalies has been generated and used to test if the algorithm gives a higher reconstruction error when these are present in the audio. Both neural networks shows promise, and with further development and training, could possibly work well in a real-life environment.

    Abstract [en]

    Miljöbyggnadscertifieringarna har ökat markant sen systemet lanserades och allt fler byggnader uppförs i Sverige idag med stort miljöfokus. Men hur bra är kvalitetskontrollerna som ska säkerställa att byggnaden uppfyller certifieringskraven? Denna rapport syftar att svara på hur noggrant kvalitetskontrollerna för certifiering av Miljöbyggnad utförs samt hur bra dessa kontroller är på att säkerställa certifieringen ur ett kvalitetsperspektiv. För att svara på syftet så undersöks och kartläggs det vilka kvalitetskontroller som gjorts på referensobjektet framtidens US i Linköping. Efter att kvalitetskontrollerna kartlagts så har de utvärderas och fått ett betyg efter utvärderingsparametrar som tagits fram i samarbete med energiexpert, kvalitetssamordnare och miljösamordnare. Alla olika typer av kontrollers betyg har lett till ett samlat indikatorbetyg som återspeglar hur bra kontrollerna kring varje indikatorn är på att säkerställa kvalitén på certifieringen. Resultatet ger en spridd bild över hur bra kontrollerna är på att säkerställa kvalitén på certifieringen. Det förekommer höga felmarginaler i kontrollerna och detta leder till ett sämre betyg. Generellt så har indikatorbetygen varit väldigt bra när det gäller att säkerställa kvalitén på certifieringen.

    The Continued Prevalence of Dichotomous Inferences at CHI2019In: CHI EA 19 EXTENDED ABSTRACTS: EXTENDED ABSTRACTS OF THE 2019 CHI CONFERENCE ON HUMAN FACTORS IN COMPUTING SYSTEMS, ASSOC COMPUTING MACHINERY , 2019Conference paper (Refereed)
    Abstract [en]

    Dichotomous inference is the classification of statistical evidence as either sufficient or insufficient. It is most commonly done through null hypothesis significance testing (NHST). Although predominant, dichotomous inferences have proven to cause countless problems. Thus, an increasing number of methodologists have been urging researchers to recognize the continuous nature of statistical evidence and to ban dichotomous inferences. We wanted to see whether they have had any influence on CHI. Our analysis of CHI proceedings from the past nine years suggests that they have not.

    Open science saves lives: lessons from the COVID-19 pandemic2021In: BMC Medical Research Methodology, E-ISSN 1471-2288, Vol. 21, no 1, article id 117Article in journal (Other academic)
    Abstract [en]

    In the last decade Open Science principles have been successfully advocated for and are being slowly adopted in different research communities. In response to the COVID-19 pandemic many publishers and researchers have sped up their adoption of Open Science practices, sometimes embracing them fully and sometimes partially or in a sub-optimal manner. In this article, we express concerns about the violation of some of the Open Science principles and its potential impact on the quality of research output. We provide evidence of the misuses of these principles at different stages of the scientific process. We call for a wider adoption of Open Science practices in the hope that this work will encourage a broader endorsement of Open Science principles and serve as a reminder that science should always be a rigorous process, reliable and transparent, especially in the context of a pandemic where research findings are being translated into practice even more rapidly.

    Reducing Affective Responses to Surgical Images and Videos Through Stylization2020In: Computer graphics forum (Print), ISSN 0167-7055, E-ISSN 1467-8659, Vol. 39, no 1, p. 462-483Article in journal (Refereed)
    Abstract [en]

    We present the first empirical study on using colour manipulation and stylization to make surgery images/videos more palatable. While aversion to such material is natural, it limits many peoples ability to satisfy their curiosity, educate themselves and make informed decisions. We selected a diverse set of image processing techniques to test them both on surgeons and lay people. While colour manipulation techniques and many artistic methods were found unusable by surgeons, edge-preserving image smoothing yielded good results both for preserving information (as judged by surgeons) and reducing repulsiveness (as judged by lay people). We then conducted a second set of interview with surgeons to assess whether these methods could also be used on videos and derive good default parameters for information preservation. We provide extensive supplemental material at .

    Hybrid Touch/Tangible Spatial 3D Data Selection2019In: Computer graphics forum (Print), ISSN 0167-7055, E-ISSN 1467-8659, Vol. 38, no 3, p. 553-567Article in journal (Refereed)
    Abstract [en]

    We discuss spatial selection techniques for three-dimensional datasets. Such 3D spatial selection is fundamental to exploratory data analysis. While 2D selection is efficient for datasets with explicit shapes and structures, it is less efficient for data without such properties. We first propose a new taxonomy of 3D selection techniques, focusing on the amount of control the user has to define the selection volume. We then describe the 3D spatial selection technique Tangible Brush, which gives manual control over the final selection volume. It combines 2D touch with 6-DOF 3D tangible input to allow users to perform 3D selections in volumetric data. We use touch input to draw a 2D lasso, extruding it to a 3D selection volume based on the motion of a tangible, spatially-aware tablet. We describe our approach and present its quantitative and qualitative comparison to state-of-the-art structure-dependent selection. Our results show that, in addition to being dataset-independent, Tangible Brush is more accurate than existing dataset-dependent techniques, thus providing a trade-off between precision and effort.

    3D Mobile Data Visualization2021In: Mobile Data Visualization / [ed] Bongshin Lee, Raimund Dachselt, Petra Isenberg, Eun Kyoung Choe, New York: Chapman and Hall/CRC , 2021, p. 111-150Chapter in book (Other academic)
    Abstract [en]

    We survey the space of three-dimensional mobile visualizations, that is, 3D abstract or spatial data on mobile 2D displays, or mobile head-mount augmented- and virtual-reality displays. As a playful “case study” we use a scenario from the film “Aliens,” in which a mobile, small-screen visualization device is used to track the movements of enemy aliens around a group of space marines. In this scenario, the marines are overrun by aliens in the ceiling, as their device fails to show them the height dimension of the space around them. We use this example to illustrate how different mobile and 3D interaction techniques could have prevented the misunderstanding in the movie, using both hypothetical descriptions of the improved movie action and a scientific discussion of these scenarios and their implications

    Publishing Visualization Studies as Registered Reports: Expected Benefits and Researchers’ Attitudes2021Conference paper (Other academic)
    Abstract [en]

    Background: Registered Reports are publications in which study proposals are peer reviewed and pre-accepted before the study is ran. Their adoption in other disciplines has been found to promote research quality and save time and resources. Objectives: We offer a brief introduction to Registered Reports and their expected benefits for visualization research. We then report a survey of the visualization community on their attitudes towards Registered Reports. This survey takes the form of a quasi Registered Report, the first one presented at a visualization venue as far as we know. Method: We will run an online survey that will be open from the end of August until the day of the alt.VIS workshop. Results: Most respondents expressed interest in Registered Reports as an additional submission format. Junior researchers as well as researchers with prior experience of preregistration tended to be more inclined to adopt this format. However, qualitative feedback highlights several perceived drawbacks and worries about Registered Reports, such as low suitability for some types of research, and increased workload for reviewers and authors. Conclusion: While many respondents expressed interest in (and sometimes enthusiasm for) Registered Reports, many also voiced concerns that should be considered and discussed in the community. Reproducibility: All the material is available on osf.io/4nrma/.

    Sneaked references: Fabricated reference metadata distort citation counts2024In: Journal of the Association for Information Science and Technology, ISSN 2330-1635, E-ISSN 2330-1643Article in journal (Refereed)
    Abstract [en]

    We report evidence of an undocumented method to manipulate citation counts involving "sneaked" references. Sneaked references are registered as metadata for published scientific articles in which they do not appear. This manipulation exploits trusted relationships between various actors: publishers, the Crossref metadata registration agency, digital libraries, and bibliometric platforms. By collecting metadata from various sources, we show that extra undue references are actually sneaked in at Digital Object Identifier (DOI) registration time, resulting in artificially inflated citation counts. As a case study, focusing on three journals from a given publisher, we identified at least 9% sneaked references (5978/65,836) mainly benefiting two authors. Despite not being present in the published articles, these sneaked references exist in metadata registries and inappropriately propagate to bibliometric dashboards. Furthermore, we discovered "lost" references: the studied bibliometric platform failed to index at least 56% (36,939/65,836) of the references present in the HTML version of the publications. This research led to an investigation by Crossref (confirming our findings) and to subsequent corrective actions. The extent of the distortion-due to sneaked and lost references-in the global literature remains unknown and requires further investigations. Bibliometric platforms producing citation counts should identify, quantify, and correct these flaws to provide accurate data to their patrons and prevent further citation gaming.

    DyStopia:Into a potential future of IEEE VIS under PlanSConference paper (Other academic)
    Abstract [en]

    In this manuscript, we take a look at the dystopian future that could lie ahead of us should we fail to consider the impact of Plan S. It is the year 2030 and researchers from Europe have not been submitted their research to IEEE VIS for a number of years. We quickly retrace what has happened to lead to this unfortunate outcome in the hope to avoid it and start an important conversation that would raise awareness in the VIS community about the importance and immediacy of Plan S.

    Open up: a survey on open and non-anonymized peer reviewing2020In: BMC Research Integrity and Peer Review, ISSN 2058-8615, Vol. 5, no 8, p. 1-11Article in journal (Refereed)
    Abstract [en]

    Background

    Our aim is to highlight the benefits and limitations of open and non-anonymized peer review. Our argument is based on the literature and on responses to a survey on the reviewing process of alt.chi, a more or less open review track within the so-called Computer Human Interaction (CHI) conference, the predominant conference in the field of human-computer interaction. This track currently is the only implementation of an open peer review process in the field of human-computer interaction while, with the recent increase in interest in open scientific practices, open review is now being considered and used in other fields.

    Methods

    We ran an online survey with 30 responses from alt.chi authors and reviewers, collecting quantitative data using multiple-choice questions and Likert scales. Qualitative data were collected using open questions.

    Results

    Our main quantitative result is that respondents are more positive to open and non-anonymous reviewing for alt.chi than for other parts of the CHI conference. The qualitative data specifically highlight the benefits of open and transparent academic discussions. The data and scripts are available on https://osf.io/vuw7h/, and the figures and follow-up work on http://tiny.cc/OpenReviews.

    Conclusion

    While the benefits are quite clear and the system is generally well-liked by alt.chi participants, they remain reluctant to see it used in other venues. This concurs with a number of recent studies that suggest a divergence between support for a more open review process and its practical implementation.

    Exploring and Explaining Climate Change: Exploranation as a Visualization Pedagogy for Societal Action2022Conference paper (Other academic)
    Abstract [en]

    Engaging mass audiences with crucial societal issues, such as cli-mate change, can be provided through interactive exhibits designed around the paradigm of exploranation. We present example inter-active installations in the newly founded Wadstr¨oms Exploranation Laboratory that explain various aspects of climate change while allowing public participants to explore the real scientific data. We describe how effects and causes of climate change can be communi-cated by two of the installations that allow for interactive opportuni-ties to explore the underlying data while gaining insight into climate change sources and effects. We close with implications for future work on exploranation as an emerging visualization pedagogy in public spaces.

    The State of the Art of Spatial Interfaces for 3D Visualization2021In: Computer graphics forum (Print), ISSN 0167-7055, E-ISSN 1467-8659, Vol. 40, no 1, p. 293-326Article in journal (Refereed)
    Abstract [en]

    We survey the state of the art of spatial interfaces for 3D visualization. Interaction techniques are crucial to data visualization processes and the visualization research community has been calling for more research on interaction for years. Yet, research papers focusing on interaction techniques, in particular for 3D visualization purposes, are not always published in visualization venues, sometimes making it challenging to synthesize the latest interaction and visualization results. We therefore introduce a taxonomy of interaction technique for 3D visualization. The taxonomy is organized along two axes: the primary source of input on the one hand and the visualization task they support on the other hand. Surveying the state of the art allows us to highlight specific challenges and missed opportunities for research in 3D visualization. In particular, we call for additional research in: (1) controlling 3D visualization widgets to help scientists better understand their data, (2) 3D interaction techniques for dissemination, which are under-explored yet show great promise for helping museum and science centers in their mission to share recent knowledge, and (3) developing new measures that move beyond traditional time and errors metrics for evaluating visualizations that include spatial interaction.

    Från klassrummet till Madison Square Garden - Hur en logotyp kan utformas för ett band2020Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [sv]

    Musikindustrin är en tuff bransch med hög konkurrens. För att en musiker idag ska kunna bli framgångsrik gäller det att ha ett genomtänkt varumärke som kan representera musikerns image. Författarna av denna studie har kommit i kontakt med indierockbandet Out of Mind som är ett relativt nytt band och som vill lansera sig själva inom musikindustrin och öka sitt igenkännande hos deras målgrupp. För att på bästa sätt identifiera bandet och särskilja dem från konkurrenter bör därför en unik logotyp utformas. Syftet med studien blir därmed att undersöka hur man kan utforma en logotyp för ett band som förmedlar dess genre, värdeord och önskad positionering. En förstudie genomfördes som gav författarna insikt om vilken genre bandet identifierar sig med, hur de önskar positionera sig, och dess värdeord: hoppfullhet, kreativitet, gemenskap och mod. För att besvara studiens syfte utformades tre logotypförslag som värderades med hjälp av en enkätundersökning. Av värderingen framkom det att värdeordet hoppfullhet bäst visades genom cirkulära former som förmedlar en positiv känsla. Kreativitet visades bäst genom en kombination av linjer och mjuka former. Värdeordet gemenskap lyftes fram bäst genom en sammanhängande typografi. Mod lyftes fram bäst genom att använda sig av ett skarpt och hårt uttryck. Bandet tillhör genren indierock, som baserat på resultatet av värderingen, framställs bäst genom att kombinera en rockig och tuff känsla med mjuka och snälla former. Baserat på resultatet av logotypernas positionering framkom det att det är viktigt att inga aspekter i positioneringen motsätter varandra då det gör det svårt att utforma logotypen, så att den förmedlar alla delar av varumärkesidentiteten.

    Astronomy Software Integration with OpenSpace2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aimed to create a messaging protocol for OpenSpace to interoperate with other astronomy software. The goal was to create a messaging standard that was not language-dependent and could be implemented by any astronomy software. To establish an asynchronous communication between OpenSpace and connected software, the Transmission Control Protocol (TCP), threading, and Peer-To-Peer (P2P) were the techniques mainly used. TCP was used to achieve reliable communication between software connected to the network. The enabling of two-way communication was solved by threading. P2P was used as a network communication architecture to share resources between the connected software. By using Unicode characters expressed through UTF-8, the Unicode Standard was used to encode messages sent. The messages are structured by combinations of different sizes of bytes and are sent and received as binary strings. All messages contain a header and the data being sent. Different message types were created to specify which type of data is sent. The protocol works primarily between OpenSpace and Glue but is not limited to these software. The implementation serves as the basis of the messaging protocol for OpenSpace, where Glue represents future software integrations.

    Utformning av en mobilapplikation med syfte att strukturera och ge stöd i vardagen för unga vuxna med ADHD2022Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    This study examines the question of how an app with the aim of providing support for young adults with ADHD in everyday life can be designed. The study sheds light on theories about the diagnosis ADHD and design principles from Bergström (2017). Our chosen methods follow Arvola's (2014) recommendations regarding UX design and Tullis and Albert's (2013) recommendations regarding data collection and usability metrics. The study includes a feasibility study, development of a paper and computer prototype, user tests, interviews and a System Usability Scale survey that formed the basis for the results' final computer prototype. The results showed that an app with this purpose should be clear, customizable and not have too many impressions. Furthermore, it was concluded that the design should feel somewhat inviting, by using soft shapes and colors as well as having the ability to be adaptable.

    Vårt blivande herrsortiment finns i din garderob - Att utforma ett kommunikationskoncept som gör fler unga män villiga att donera kläder till second hand2020Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    The textile industry is a major environmental issue in today’s society and a high demand fornew produced clothing contributes to the environmental impact. The re-use of clothing is aresource efficient way to be more environmental friendly, which can be accomplishedthrough the second hand market. Because of a limited assortment of men’s clothing, youngmen rarely shop at second hand stores. The study therefore aims to research how acommunication concept could be designed to make more young men willing to donateclothes to second hand stores.This study resulted in the communication concept Garderobsrensningsdagarna. The concepttakes the form of a collection campaign that highlights the wardrobe, as the main problemlies within that the target group are not sorting out their wardrobes. The concept wasevaluated by qualitative interviews. These showed that the concept should highlight thewardrobe as an unused resource. An environmental focus should be included in the conceptat the same time as an accessible way of donating should be offered. To motivate the targetgroup to donate clothes to second hand stores, the evaluation showed that the conceptshould create a feeling of fellowship, include a clear goal, a time limit and generate directfeedback. To create a high level of involvement, the concept should attract attention and sogenerate word-of-mouth.

    Extractive Text Summarization of Norwegian News Articles Using BERT2021Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Extractive text summarization has over the years been an important research area in Natural Language Processing. Numerous methods have been proposed for extracting information from text documents. Recent works have shown great success for English summarization tasks by fine-tuning the language model BERT using large summarization datasets. However, less research has been made for low-resource languages. This work contributes by investigating how BERT can be used for Norwegian text summarization. Two models are developed by applying a modified BERT architecture, called BERTSum, on pre-trained Norwegian and Multilingual BERT. The results are models able to predict key sentences from articles to generate bullet-point summaries. These models are evaluated with the automatic metric ROUGE and in this evaluation, the Multilingual BERT model outperforms the Norwegian model. The multilingual model is further evaluated in a human evaluation by journalists, revealing that the generated summaries are not entirely satisfactory in some aspects. With some improvements, the model shows to be a valuable tool for journalists to edit and rewrite generated summaries, saving time and workload.
