    Artilleriplattform Amfibie - Tekniska sensorer för självskydd ur ett användarperspektiv: En kvalitativ intervjustudie om användares behov2022Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Materiel acquisition for The Swedish Armed Forces (Försvarsmakten) is made by The Swedish Defence Materiel Administration (Försvarets materielverk) and is a rigorous and expensive process. The incentives to produce adequate material for the users are high, but how is the process of producing adequate material for the users best achieved? Theoutcome of these processes is to some extent judged by the satisfaction of the users. So wouldn't it be advantageous toinclude them in the process? By using theories of USCE (User centred systems engineering) and PD (Participatory Design) the purpose of this thesis is to examine future users expressed needs of technical sensors, for a high-speed artillery vessel with an integrated grenade launcher. The thesis also examines how theories and methods of USCEand PD can be applied to find out user needs in specific defined contexts. The study does so by using a series of scenarios presented in text and graphically. The interviewed users were asked to express their needs in relation to specific situations and threats in the scenario. The users’ expressed needs are later translated into a set of possible technical sensors for self-defence of the high-speed artillery vessel. The core idea of USCE is designing with the user in consideration. The core idea of PD is to design with the user, enabling for more valid information to be extractedand put into design. In this case it was done by presenting nine scenarios, where the respondents were asked what they wanted to know and what they wanted to do. In addition to answering questions, they were also encouragedto draw graphic information on the illustrations of the scenario material. This was done to enable transfer of additional knowledge and information from the respondents. The analysis suggests a combination of technical sensors that was found to correspond to the expressed user needs. It was also found that USCE and PD can be used to better identify user needs. However, the methods and activities for doing so can benefit from further studies. The presented combination of technical sensors for self-defence might reflect the expressed needs of users, it is however not necessarily the best solution for this high-speed artillery vessel. The best solution also needs to account for factors like budget and the role of the high-speed artillery vessel in a larger context. The presented sensor solution could be further validated if tested together with potential users. The result of this study might however contribute to more substantiated decisions for the final design of the artillery platform, as well as showing the importance of involving users and carefully chosen activities for doing so.

    Gamification - Den roliga inlärningsvägen till digitala internutbildningar: Är digitala internutbildningar med gamification roligare?2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Digital training education exists to help businesses educate their employees to improve their performance as well as to protect the business from being exploited. Gamification is the application of game mechanisms in a non-game context and is used within companies as its perceived potential makes learning more engaging and fun. There is not yet much research that actually proves whether gamification can help companies for educational purposes or not. The study investigated whether gamification makes digital training education more fun or not by comparing two companies where one used gamification and the other did not. The data collected came from questionnaires that provided both qualitative and quantitative data. The data has been analyzed with a T-test and a thematic analysis to provide an empirical contribution to the research regarding gamification. The results show that gamification has a significant impact on making digital internal training more fun from both the T-test and the thematic analysis.

    Gymnasielärares upplevelser av digitaliserad distansundervisning: En kvalitativ intervjustudie2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Som följd av pandemin covid-19 och rekommendationer från Folkhälsomyndigheten tvingadesgymnasieskolor i Sverige att anpassa sin undervisning till distansundervisning. Digitalaverktyg blev därför en viktig del för gymnasielärare för att kunna fortsätta undervisningen.Tidigare forskning visar varierande resultat på distansarbetets effekter och utgår främst frånfrivilliga verktyg som möjliggör distansarbete. Utifrån faktorer kopplade tillanvändaracceptans är studiens syfte att undersöka gymnasielärares upplevelser avdistansundervisning och hur den har påverkat deras arbete. För att besvara studiensfrågeställning genomfördes semistrukturerade intervjuer med gymnasielärare från Uppsala.Resultatet visar att distansundervisning även under obligatoriska förhållanden till stor delupplevs negativt, baserat på de tre teman som producerats utifrån gymnasielärares intryck ocherfarenheter av distansundervisning. De tre centrala teman som undersökts är: kommunikationmellan lärare och elever, arbetsbörda samt digitala verktyg.

    Optimisation of Ad-hoc analysis of an OLAP cube using SparkSQL2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    An Online Analytical Processing (OLAP) cube is a way to represent a multidimensional database. The multidimensional database often uses a star schema and populates it with the data from a relational database. The purpose of using an OLAP cube is usually to find valuable insights in the data like trends or unexpected data and is therefore often used within Business intelligence (BI). Mondrian is a tool that handles OLAP cubes that uses the query language MultiDimensional eXpressions (MDX) and translates it to SQL queries. Apache Kylin is an engine that can be used with Apache Hadoop to create and query OLAP cubes with an SQL interface. This thesis investigates whether the engine Apache Spark running on a Hadoop cluster is suitable for analysing OLAP cubes and what performance that can be expected. The Star Schema Benchmark (SSB) has been used to provide Ad-Hoc queries and to create a large database containing over 1.2 billion rows. This database was created in a cluster in the Omicron office consisting of five worker nodes and one master node. Queries were then sent to the database using Mondrian integrated into the BI platform Pentaho. Amazon Web Services (AWS) has also been used to create clusters with 3, 6 and 15 slaves to see how the performance scales. Creating a cube in Apache Kylin on the Omicron cluster was also tried, but was not possible due to the cluster running out of memory. The results show that it took between 8.2 to 11.9 minutes to run the MDX queries on the Omicron cluster. On both the Omicron cluster and the AWS cluster, the SQL queries ran faster than the MDX queries. The AWS cluster ran the queries faster than the Omicron cluster, even though fewer nodes were used. It was also noted that the AWS cluster did not scale linearly, neither for the MDX nor the SQL queries.

    Investigation of a method to extend the use of output data from Scania's Hardware-In-the-Loop simulations: Development of database and search algorithm2014Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In the automotive industry, Hardware-In-the-Loop (HIL) laboratories are used for testing vehicle functions and systems. Swedish heavy truck manufacturer Scania recently upgraded its HIL lab resulting in an opportunity to save all data generated by simulations in the HIL lab for post analysis. Thus, Scania wished to investigate the possibility to extend the use of output data by examining a new test method. The new test method was intended to be used for disclosing a type of error that had not been possible to detect prior to the upgraded HIL lab. The proposed test method was to store tests in a database and to run the tests upon output data generated in the HIL lab. The tests which were to be stored in the database existed as scripts written in the programming language Python. In order to insert tests into the database the data had to be extracted from the Python test scripts. The investigation showed the database test method to be feasible in small scale for some test scripts but the results also indicated weaknesses with the method’s setup. Insertion of data, extracted from test scripts, into a relational database showed to be problematic as the data was highly heterogeneous and did not fit easily into relational tables. For future implementations it is suggested that the method incorporates other information sources complementing the test scripts.

    Decision-making AI in digital games2022Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The field of artificial intelligence has gained much knowledge through the implementation of decision-making systems in video games. One of these systems was the Goal Oriented Action Planning system (GOAP) which directs the behavior of an AI-agent through multiple digital artifacts categorized as goals, actions, and plans. The aim of the thesis is to aid in the understanding and creation of GOAP driven AI-agents in a video game setting to promote research on this topic. The research question of this thesis was about finding out how the GOAP architecture compares to other video game decision-making systems. The theoretical framework introduces the concept of the illusion of intelligence in video games and presents a discussion focused on the different components which make up a GOAP system and other components that support it. Additionally, the theoretical framework explains the need for a comparison between different decision-making systems and explains the social impact of game AI research. The methods section introduces the criteria for the comparison between GOAP and other decision-making systems and presents a comparison process that was driven by a literature review. A GOAP system was designed for this thesis using the unified modeling language and concept maps. It was then implemented using C# code in a free-of-charge game engine called Unity. We present the pseudocode for the implementation of the GOAP system and show that this framework is a modular, customizable, and reusable system that enables AI-agents to create plans from a varied set of actions. Finally, the paper suggests further research within game decision-making AI and emphasizes the importance of game AI research for communities of game developers, hobbyists, and others who could benefit from game AI in their projects.

    The Digital Transformation of the Swedish Banking Industry: A study on the digitalisation of Swedish banks and how it affects their perspective on customer experience2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The Swedish banking industry has long been at the forefront when it comes to digital leadership. Currently, this industry is starting to fall behind other industries, and a closer look at the industry reveals that niche banks are having less trouble with adapting new technologies than bigger banks. There are a lot of studies on specific digitalisation areas within banking but nothing comprehensive about the strategies required for digital transformation within the banking industry. As the research area is new, there is little previous research on digital transformation by today’s standards. Therefore, the centralquestion in this thesis is “What do respondents in the Swedish banking industry think that the most important factors of digitalisation for customer experience are and what the consequences of digitalisation might be?” to find out what affects the digital strategies of a sample of Swedish banks. To answer the research question, semi-structured interviews with relevant profiles in the banking industry dealing with digitalisation and strategy at a management level were conducted.

    The interviews were conducted with five respondents from four different banks. In combination of this research method, the research strategy Case Study was implemented. The results revealed that digitalisation is in high focus amongst all the responding banks, for various reasons. The reasons can be seen as roughly divided into two categories, internal reasons and external reasons. The internal reasons have to do with streamlining current internal processes and creating more available resources for other projects. The external reasons were all towards improving customer experience. To improve customer experience, personalisation of the digital products and services is a key factor. However, personalisation is not without risk, as it may fail to be personalised enough for the banks’ customers if the personalisation is attempted towards a too wide customer segment.

    Some of the banks are operating 100% digitally, meaning that they do not have any physical bank offices for customers to visit, and thus all their work then becomes in one way or another digital work. The banking and finance industry is continually changing, and legal factors play a significant role. Not only do these legal factors affect how banks work internally, they also affect the competitiveness of the various actors and with it, how much digitalisation can affect. The thesis concludes that digital transformation is heavily influencing the strategies of banks in the Swedish banking industry through customer needs, competition and legal factors.

    Att köra eller att inte köra: ett steg mot en acceptansmodell för självkörande fordon2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Självkörande fordon har tillskrivits fördelar såsom reducering av trafikolyckor samt bränsleutsläpp. Samtidigt återfinns en påtaglig upplevd osäkerhet för tekniken hos potentiella användare. Syftet med denna studie var att vidareutveckla och testa en acceptansmodell för självkörande fordon. De undersökta variablerna baserades på Technology Acceptance Model (TAM), utökad med tillägg för förtroende och risk samt kompatibilitet. Variablerna bildade studiens modell tillsammans med tolv formulerade hypoteser för sambanden mellan dessa. Med enkät som datainsamlingsmetod analyserades svar från 125 respondenter med partial least squares structural equation modelling (PLS-SEM). Resultatet som erhölls visade på att studiens modell har en betydande förklarande förmåga på 78 procent. Vidare kunde åtta av studiens tolv hypoteser accepteras, samtliga med en signifikansnivå på 0,1 procent (p < 0,001). De statistiskt signifikanta resultaten för upplevd säkerhetsrisk och initialt förtroende samt kompatibilitet motiverar dessa tillägg till TAM. För urvalet fann studien att attityd och kompatibilitet har en direkt positiv påverkan på avsikt att använda fullt självkörande bilar. Attityd i sin tur påverkas positivt av kompatibilitet och initialt förtroende. En reducerad upplevd säkerhetsrisk och ökad upplevd nytta samt upplevd användarvänlighet medför ett ökat initialt förtroende. Tre av de fyra icke-signifikanta hypoteserna som erhölls är samband som postuleras i den ursprungliga versionen av TAM, varvid fortsatt forskning och vidare bearbetning av studiens modell kan behövas. Studiens resultat kan praktiskt fungera vägledande för utvecklare och tillverkare av autonoma fordon, samt för politiska beslutsfattare i ett led att försöka uppnå målsättningar såsom nollvisionen.

    Användarnas uppfattning av persuasive design på en social plattform: En fallstudie om hur persuasive design utspelar sig ien social plattform och om hur användare uppfattar tekniken2024Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Persuasive design är den teknik som används för att ändra eller vägleda användarens handlingar och beteenden genom IT-system. En bra källa att implementera detta på är sociala plattformar då det med enkelhet når användarna. Denna fallstudie syftar till att undersöka hur persuasive design i den sociala plattformen Instagram utspelas genom Fogg behavior Model (FBM). FBM är en modell framtagen för att undersöka vilka komponenter i ett digitalt system som bidrar till mänskligt beteende. fallstudien utförs genom en förstudie som identifierar persuasive design på Instagram. Därefter följs en enkätundersökning som undersöker vilken uppfattning och inställning användare har om tekniken persuasive design. Vidare utförs även en intervju för att få mer djupgående information om användarnas uppfattning och kunskap om tekniken persuasive designs i den sociala plattformen. Resultatet visar att användarna inte har en större uppfattning om tekniken persuasive design, en majoritet hade en negativ inställning till tekniken, användarna har dock uppmärksammat att det framkommer beteende förändrande algoritmer på Instagram.

    Artificiell Intelligens framtidsutsikter inom sjukvården: En studie om studerande sjuksköterskors attityder gällande Artificiell Intelligens inom sjukvården2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Artificial Intelligence is an area that has developed radically in recent years and is constantly evolving in several industries. In this thesis, a qualitative case study is conducted which addresses student nurses' attitudes regarding Artificial Intelligence in Swedish healthcare and its use in the future. Through interviews conducted with Uppsala University student nurses, the empirical material is analyzed using the Technology Acceptance Model (TAM) theory to finally produce a result regarding the future use of Artificial Intelligence in healthcare. The analysis resulted in two evident areas regarding AI usage: decision-making AI and non-decision-making AI where the participants’ attitudes differed between the two divisions. The attitudes towards decision-making AI were rather negative partly because of the lack of responsibility and accountability together with the reduced patient contact it would entail. The attitudes towards non-decision-making AI were, in contrast, considered positive, partly because of the efficiency it would imply using AI technology as an appliance and the areas of improvement it would entail in the profession. For example by creating time for more care and attention, something that nursing students imply is the main focus in health and social care. Finally, the results of the analysis are discussed based on various aspects such as ethics and morals, the profession itself and further research.

    A Single-Minded Market for Digital Assets?: Copyright clearance of orphan works in the digitisation ecosystem2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This dissertation assesses the Swedish and the United Kingdom (UK) legislative frameworks for cross-border copyright clearance of orphan works in mass-digitisation schemes. By reviewing relevant copyright frameworks and practices around the world, interviewing Swedish and British experts in the field of libraries and copyright, and discussing the national solutions applied in Sweden and the UK, conclusions are drawn to form a roadmap for future policy work in the area.

    The findings are that even though copyright clearance systems for orphan works work well in their national context, they wouldn’t be transferable to a cross-border context due to the different legal and societal traditions in the EU Member States. Solutions for cross-border access could be a general copyright law exception (which is a time-consuming process and therefore less usable in practice in the next 5-10 years), create and build on rightsholder registers with increased collaboration with CMOs, changed management of digital collections (e.g. only digitising orphan works that are in the public domain), or work towards soft legislative solutions (such as an MoU).

    Abstract [en]

    This thesis is a case study of the search function on the University of Uppsala’s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical. Without a common strategy how to handle information is it very difficult to make good searches on the web site.

    Harness mobility: Managing the off-task property2010In: DESRIST 2010: The 5th International Conference on Design Science Research in Information Systems and Technology 2010, in St Gallen, Switzerland / [ed] Stephan Aier, Springer , 2010Conference paper (Refereed)
    Abstract [en]

    Technological advancements in mobile computing and wireless networks open up to new applications and new user-groups in the mobile workforce. However, a considerable part of the mobile workforce, such as e.g. drivers or healthcare staff, is chiefly performing other tasks than interacting with their computers. As a result, they are not able to pay attention to computer interaction, making them mainly off computer tasks. The aim of the paper is to develop a design theory to manage off-task situations in mobile computing. Interviews were performed with developers of an information system comprising mobile devices for drivers. From the interviews, a design of an artifact and a design theory based on a strategy to automate routine administration task using place awareness is presented. The eight components of IS design theory by Gregor and Jones is applied as a theoretical framework.

    Världsbäst i digitalisering?: En explorativ fallstudie om den pågående digitaliseringsprocessen av den svenska skolan2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Swedish society is constantly evolving and growing into higher levels of digitalisation. The school system plays an important part in creating a nationwide competence regarding the proper use of digital tools, by growing alongside the society as a whole. In the spring of 2017 the Swedish government issued a public document called the national strategy of digitalization, which defines certain goals for the school system to achieve. The Swedish Association of Local Authorities and Regions (SKL) is in the process of developing a plan of action, which is to be a document used for guiding people working within the school system towards reaching the goals within the national strategy of digitalization. A few initial changes have now been made to the general curriculum and it has raised several questions, regarding the good, bad or even unmanageable consequences that such changes will lead to. This study aims to look into the ongoing discussion and define specific areas of future research. A number of key actors with different roles within and in relation to the school system have been interviewed. Among the results is a model depicting several major actors within the digitalization process and how they relate to each other. The theoretical framework TPACK is used to analyze and discuss the complexity of a general level of competence that is required of teachers working within a digitalized school system. Two areas of future research have been defined: (1) Continuous study and evaluation of the action plan; (2) Proper use and integration of digital study material.

    Utmaningar vid CRM-implementering: En tvärvetenskaplig fallstudie om implementering av CRM-system hos en tidningskoncern2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study is about Customer Relationship Management (CRM) and implementation of CRM systems. The study aims to identify and investigate which challenges are experienced during CRM implementation at a newspaper group and how those challenges have been handled. Through a case study at the newspaper group, the investigation has had an inductive and exploratory approach where the focus has been to achieve a deeper understanding of the implementation as well as the challenges experienced and managed. The data collection was carried out in the form of semi-structured interviews with managers, support staff and salespeople at the group. Through a thematization of the empirical findings, five different themes have been identified. These consist of resistance to change, the changed sales role, training and support, system limitations and the user perspective. These themes have then been analyzed and the challenges that have been experienced and how these have been handled emerge. The study found that various types of challenges emerged based on the identified themes, which further impacted different roles within the group. The results of the study indicate that some challenges were successfully addressed, while others were not.

    Cloud Computing: Lärplattform i molnet2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The growth of cloud computing has enabled the provision of computer resources online and offers two essential characteristics, illusion of infinite supply and pay-per-use. Learning management systems are currently used extensively by the Swedish universities as learning tools. This brings better opportunities for distance courses and e-learning. To combine cloud computing with a learning management system is now possible and should therefore give the schools benefits. If the Learning management system is hosted as a cloud service by an external provider, so should the requirements be different.

    The purpose of this paper is to investigate whether there are any incentives for rent a learning management system as a cloud service and also investigate if the requirements are different in a rented cloud service. A case study was conducted at Uppsala University and Dalarnas University, in order to compare a learning management system installed on their own server with a learning management system rented as a cloud service. 

    The result of the study proves that there are advantages to rent a learning management system as a cloud services. In terms to the requirements, there are no great differences. An important requirement when the learning management system is hosted by a supplier is that there is a good dialogue and that the organization relies on the supplier.

    Low-Code Development Life Cycle: En beskrivning hur systemutvecklings-verksamheter hanterar Software Development Life Cycle-processer i low-code plattformar2022Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study examines how systems development operations manage the Software Development Life Cycle (SDLC) in a Low-Code Platform (LCP) and how these descriptions relate to today's SDLC standards. To investigate this, a case study for a specific LCP has been made. Semi-structured interviews have been carried out with the aim of investigating theSDLC managed in the investigated LCP. An analysis model based on ISO/IEC/IEEE12207:2017 has been used for a deductive thematic analysis. The analysis shows a great breadth regarding how system development operations can integrate an LCP into their IT infrastructure and work with it. The choice of strategy will control how the system development operation works with the SDLC for IT artifacts that are developed in theplatform. In order for the organization to be able to enjoy the benefits of the LCP, business processes need to be possible to model in the platform. Complex and extensive business rulesaffect the possibilities to model business logic through low-code in the platform. Addressing this through traditional code can increase the complexity of certain elements of the SDLC and the need for expertise, which can significantly increase resource requirements and the time required for the system development process.

    Learning Whole-Slide Segmentation from Inexact and Incomplete Labels Using Tissue Graphs2021In: Medical Image Computing and Computer Assisted Intervention: MICCAI 2021, Cham: Springer Nature, 2021, p. 636-646Conference paper (Refereed)
    Abstract [en]

    Segmenting histology images into diagnostically relevant regions is imperative to support timely and reliable decisions by pathologists. To this end, computer-aided techniques have been proposed to delineate relevant regions in scanned histology slides. However, the techniques necessitate task-specific large datasets of annotated pixels, which is tedious, time-consuming, expensive, and infeasible to acquire for many histology tasks. Thus, weakly-supervised semantic segmentation techniques are proposed to leverage weak supervision which is cheaper and quicker to acquire. In this paper, we propose SEGGINI, a weakly-supervised segmentation method using graphs, that can utilize weak multiplex annotations, i.e., inexact and incomplete annotations, to segment arbitrary and large images, scaling from tissue microarray (TMA) to whole slide image (WSI). Formally, SEGGINI constructs a tissue-graph representation for an input image, where the graph nodes depict tissue regions. Then, it performs weakly-supervised segmentation via node classification by using inexact image-level labels, incomplete scribbles, or both. We evaluated SEGGINI on two public prostate cancer datasets containing TMAs and WSIs. Our method achieved state-of-the-art segmentation performance on both datasets for various annotation settings while being comparable to a pathologist baseline.

    Abstract [en]

    Mobilitet hos människor har ökat inom många områden i och med utvecklingen och framväxten av den mobila teknologin. Ett av de områden som har blivit påverkat av denna tekniska utveckling är lärande och utbildning både inom arbetslivet och inom skolvärlden. Idag beräknas många yrkeskategorier tillbringa mer än halva sin arbetstid utanför arbetsplatsen. Antalet abonnenter som har tillgång till trådlöst Internet förväntas öka lavinartat under det närmaste decenniet. Digital information och inlärningsmaterial ryms redan nu i våra fickor och vi har möjlighet att koppla upp oss mot varandra och kommunicera oavsett plats och tidpunkt.

    Syftet med rapporten är att presentera de olika formerna av lärande, dvs. distanslärande, elektroniskt lärande och mobilt lärande. Betoningen i detta arbete är på den sistnämnda lärandeformen, mobilt lärande. En jämförelse mellan mobilt lärande och livslångt lärande genomförs och likheterna mellan dessa diskuteras. Syftet är också att diskutera användningen av mobilteknik och mobilt lärande inom utbildningsväsendet och vården i syfte att effektivisera lärandet, kommunikation, kunskapshantering och arbete. Detta för att kunna införa och uppnå en optimal form av livslångt mobilt lärande och mobilt arbete i våra skolor och inom arbetsplatser med hjälp av den nya tekniken.

    Spelifiering inom rekryteringsprocesser: En kvalitativ fallstudie av det spelifierade rekryteringsverktyget Skyrise City2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Effektiv rekrytering är en viktig faktor för att ett företag ska bli framgångsrikt. För att hamna i framkant inom rekrytering har företag börjat använda alternativa tillvägagångssätt. En metod som blir allt mer vanligt förekommande inom rekrytering är spelifiering. Spelifiering definieras som användandet av spelbaserade element, estetik och speltänkande för att engagera människor, motivera handlingar, främja lärande och problemlösning, i en icke spelrelaterad kontext. Syftet med denna studie är att undersöka hur spelifiering används inom rekrytering samt vad för konsekvenser det medför. En kvalitativ fallstudie har genomförts och undersökt game-based assessmentverktyget Skyrise City, utvecklat av Arctic Shores. Fallstudien har realiserats på ITföretaget EVRYs rekryteringsprocess och deras användning av Skyrise City. Studien bygger på ett antal semistrukturerade intervjuer, där sakkunniga personer inom rekrytering och spelifiering vid företagen har intervjuats. Resultatet analyserades utifrån ett teoretiskt ramverk sammansatt av fem traditionella rekryteringsmoment. De slutsatser som kan dras av studien är att spelifiering i rekryteringsprocessen används inom games, gamified assessments och gamebased assessments. De konsekvenser som spelifiering medför till en rekryteringsprocess är bland annat: game-based assessments mäter vad du gör snarare än vad du säger, det kan stärka ett företags arbetsgivarvarumärke, det kan leda till ökade kandidatansökningar, det kan vara mer tidseffektivt, det är svårare att fuska till sig bra resultat, samt ger bättre möjligheter för kundanpassning.

    Enterprise systems Configuration as an Information Logistics Process - A Case Study2007In: Proceedings of 9th International Conference on Enterprise Information Systems: ICEIS-2007, 2007, p. 10-Conference paper (Refereed)
    Abstract [en]

    In this paper, we suggest using rule-based descriptions of customer’s requirements for Enterprise Systems implementing Information Logistics. The rules are developed from the users’ requirements and inserted as schedules to the Enterprise System. The output, from testing these rules, is a list of modules and parameter setting to configure the system. By using rules, we can, at least partly, automate the configuration process for traverse the several modules and thousands parameters there are in an Enterprise System. From the list, we can select the modules and the parameters that meet the customer’s requirements. Then these selected modules and parameters are visually presented through a kind of Unified Modeling Language diagrams, to support the user investigation and then to configure the system either manually or automatically. Every attempt to match a customer’s requirement to the contents of the knowledge base within the Enterprise system can be thought of as an Information Logistics Process. The output from such a process must be examined by the user, which can give rise to a new call to the Information Logistics process. In other words the configuration work is done through a dialogue between the customer and the knowledge base of the Enterprise system.

    Information coordination using Meta-Agents in Information Logistics Processes2008In: Proceedings of Knowledge-Based and Intelligent Information & Engineering Systems: KES2008, Berlin, Heidelberg: LNCS/LNAI, Springer-Verlag , 2008, p. 788-798Conference paper (Refereed)
    Abstract [en]

    In order to coordinate and deliver information in the right time and to the right place, theories from multi-agent systems and information logistics are combined. We use agents to support supply chain by searching for company specific information. Hence, there are a vast number of agents working at the Internet, simultaneously, which requires supervising agents. In this paper, we suggest using meta-agents to control the behaviour of a number of intelligent agents, where the meta-agents are working with coordination of the communication that takes place in a supply chain system. As an example, we look at a manufacturing company receiving orders on items from customers, which need to be produced. The handling of this distributed information flow can be thought of as an Information Logistics Processes and the similarities of the functioning of processes and intelligent agents’ behaviour are illuminated.

    Abstract [en]

    Purpose – The purpose of this paper was to identify factors that give rise to resistance behaviours when implementing ERP-systems. The purpose was also to find ways to prevent these resistance behaviours.Methodology – This paper was conducted through examination and use of a methodology called documents. The paper was built upon existing secondary data. The secondary data was made up of articles and books from world leading academic journals in the area of ERP-implementation.Findings and results – The findings of this paper suggests that all ERP-implementations will face human resistance of some kind and that the treatment of these resistance behaviours is crucial for a successful implementation project. The paper identified important resistance factors that need to be handled: Low commitment from top management, inadequate training and education, a project group with little influence, experience and skills, poor change management and passive management styles, system quality, system reliability, poor business vision and poor strategy plans. The paper also identified the planning phase of an ERP-implementation to be the most crucial phase in the whole project. The paper presents ways to prevent the resistance threat through some important factors: A clear business plan and vision of the project is needed and this vision must be visible to people using the system, strong support from top management and the board is needed for funding and influence on lower levels of organizations, good anticipation of changes in processes connected to the implementation, support and communication with relevant stakeholders, a strong and influential project group, training and education to overcome knowledge barriers and developed change management strategies.Originality – This paper provides an examination and summary of the most critical factors that influence resistance behaviours when implementing an ERP-system and also provides a model that can be used in organizations when facing an implementation project.Keywords – ERP, ERP-implementation, resistance behaviours, ERP-implementation phases.

    Suggesting Points-of-Interest via Content-Based, Collaborative, and Hybrid Fusion Methods in Mobile Devices2018In: ACM Transactions on Information Systems, ISSN 1046-8188, E-ISSN 1558-2868, Vol. 36, no 3Article in journal (Refereed)
    Abstract [en]

    Recommending venues or points-of-interest (POIs) is a hot topic in recent years, especially for tourism applications and mobile users. We propose and evaluate several suggestion methods, taking an effectiveness, feasibility, efficiency and privacy perspective. The task is addressed by two content-based methods (a Weighted kNN classifier and a Rated Rocchio personalized query), Collaborative Filtering methods, as well as several (rank-based or rating-based) methods of merging results of different systems. Effectiveness is evaluated on two standard benchmark datasets, provided and used by TREC’s Contextual Suggestion Tracks in 2015 and 2016. First, we enrich these datasets with more information on venues, collected from web services like Foursquare and Yelp; we make this extra data available for future experimentation. Then, we find that the content-based methods provide state-of-the-art effectiveness, the collaborative filtering variants mostly suffer from data sparsity problems in the current datasets, and the merging methods further improve results by mainly promoting the first relevant suggestion. Concerning mobile feasibility, efficiency, and user privacy, the content-based methods, especially Rated Rocchio, are the best. Collaborative filtering has the worst efficiency and privacy leaks. Our findings can be very useful for developing effective and efficient operational systems, respecting user privacy. Last, our experiments indicate that better benchmark datasets would be welcome, and the use of additional evaluation measures-more sensitive in recall-is recommended.

    Exploring User Trust in Natural Language Processing Systems: A Survey Study on ChatGPT Users2024Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    ChatGPT has become a popular technology among people and gained a considerable user base, because of its power to effectively generate responses to users requests. However, as ChatGPT’s popularity has grown and as other natural language processing systems (NLPs) are being developed and adopted, several concerns have been raised about the technology that could have implications on user trust. Because trust plays a central role in user willingness to adopt artificial intelligence (AI) systems and there is no consensus in research on what facilitates trust, it is important to conduct more research to identify the factors that affect user trust in artificial intelligence systems, especially modern technologies such as NLPs. The aim of the study was therefore to identify the factors that affect user trust in NLPs. The findings from the literature within trust and artificial intelligence indicated that there may exist a relationship between trust and transparency, explainability, accuracy, reliability, automation, augmentation, anthropomorphism and data privacy. These factors were quantitatively studied together in order to uncover what affects user trust in NLPs. The result from the study indicated that transparency, accuracy, reliability, automation, augmentation, anthropomorphism and data privacy all have a positive impact on user trust in NLPs, which both supported and opposed previous findings from literature.

    Potentiella säkerhetsrisker med växelriktare för solceller2024Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis investigates the risks associated with connected inverters in solar power installations, focusing on properties owned by Vasakronan, a real estate company with 166 properties, that has invested in solar panel installations on a majority of its buildings. The thesis explores the potential security measures related to both energy and information. Energy security encompasses multiple aspects of ensuring a reliable supply of energy within an infrastructure, necessitating tools for balancing energy production and usage and minimizing dependence on single resources. Robust information security requires the preservation of confidentiality, integrity and availability, which is considered given the organization, cloud and communication security. Interviews were conducted with representatives from Vasakronan’s suppliers of inverters, IT service provider, employees and external field experts. One property served as a case study to understand the internal real estate network structure and data on energy consumption, production and prices was collected. The risk of security breaches was assessed as the sum of factors influencing the likelihood of intrusion, as well as the consequences of such breach. Interviews with employees and IT service providers revealed Vasakronan’s awareness of information security and continuous efforts to enhance it. Interviews with inverter suppliers show varying levels of commitment to information security, with a general recognition of its importance but inconsistent knowledge of mitigation strategies. Many suppliers are cautious about production location, expressing skepticism about Chinese intelligence activities. However, the current risk for Vasakronan and the Swedish power grid is considered low, though the increasing use of solar panels may heighten this risk in the future. Specific threats such as extortion attempts, are identified as more probable, potentially resulting in production interruptions and increased energy costs. The importance of risk diversification through security measures and supplier diversification is concluded from the interviews with field experts. Data analysis indicates that security breaches primarily entail economic losses for Vasakronan, while the societal consequences are seen as potentially serious but unlikely in the short term. The thesis contributes to understanding the risks and the necessity of security measures in solar power installations through an analysis of potential energy and economic consequences of data breaches.

    The impact and power of Business Intelligence (BI) on the Decision making process in Uppsala University: A case study2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Information Systems (IS) is the use of Information Technology (IT). Business Intelligence (BI) is a specific type of IS. A BI system is an information system that uses tools to produce and deliver information. BI has become very important in the recent era as the organizational environments are getting more complex and changing faster than ever before.

    Research on BI uses in academia has been somewhat limited so far. Most decisions in a university are made based on large amounts of data from internal and external sources. So, a BI tool is necessary there in operational and strategic decision making, and also to compete well in the global environment which is very important for an international university like Uppsala. We made a case study on the large BI tool at Uppsala University. The tool has been used for more than ten years with around five hundred regular users currently. The system is called GLIS (in Swedish: Generellt Lednings Informations System) for Generalized Management Information System. It would be very interesting to investigate how the adoption of this BI system may influence the decision making process in Uppsala University, and thus it becomes the main purpose of this thesis.

    An inductive approach using a qualitative method was used in this thesis. The data collection was carried out by interviewing seven experts at Uppsala University and from some documents provided by them. Techniques from the grounded theory approach were applied for analyzing data. Our analysis shows positive effects of GLIS in Uppsala University with big improvements in decision making. The thesis draws a conclusion that the BI tool does affect the decision making process in UU as decision making activities take less time, provide better quality decisions, and are much easier using the tool. The thesis also suggests some possible improvements of GLIS for a better functionality and more user involvement. For IS practitioners, the thesis shows the power of IS tool in decision making and university management. For the IS research community, the thesis contributes with the extension of existing theory on BI uses in academia.

    Users’ intention to systematically integrate healthcare information technology in a mandated context: A continuance perspective2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aimed to investigate the determinants of system satisfaction and the intention to systematically integrate a system from a continuous use perspective, where system use is mandatory. For this purpose, two identical questionnaires were distributed to collect data, 15 months apart. Respondents taking part in this study are healthcare multi-professionals who pertain to a work-group at an intensive care unit, at a large Swedish hospital. To evaluate the questionnaire data a research model was conceptualized, grounded in prior information system continuance research. It is also significantly influenced by the UMISC metamodel, conceptualized and suggested by Hadji & Degoulet (2016). The collected data was then analyzed using a two-stage analysis where one aspect was comparative, i.e., a comparison of the data between the two questionnaires, and the other was explorative, wherein research model constructs and their relations were evaluated. This analysis provided significant insight into the determinants of system satisfaction. However, regarding the determinants of the intention to systematically integrate as well as the research model itself, neither could be validated in this study. Nevertheless, these results allowed for a modified model to be conceptualized, with potentially promising results.

    Business Intelligence in Uppsala Univeristy - Do academic institutions practice what they preach?2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Business Intelligence (BI) is not a new concept. However, it is still complicated to work with it due to the different views and ways of implementation. This study has adopted an organisational oriented approach of BI: getting the right information, to the right people, at the right time. It was found in this study that poorly implemented BI features and inadequate information infrastructure may lead to workarounds in order to compensate for missing or lacking features and systems.

    This case study has been conducted at the faculty of Social Sciences of Uppsala University (UU) where a set of interviews were conducted to individuals on one of the key positions at the university; the Director of Studies (DoS). The aim was to map out the key processes and head activities of the DoS’s and evaluate them through the BI view of this thesis. Being the conclusion a concrete mapping of the DoS head activities as well as BI assessment of the current situation of the studied departments. Some improvements have been proposed in order to remedy the lacking of valuable and critical features and systems. However, it was found that the current system infrastructure and problem area is too immature in order to implement any form of integration. Several studies on key positions and influential systems need to be conducted in order to exhaustively map out and discover the problem area.

    The perceived image of multi-asset tourist destinations: investigating congruence across different content types2021In: Service Business: An International Journal, ISSN 1862-8516, E-ISSN 1862-8508, Vol. 16, no 1, p. 57-75Article in journal (Refereed)
    Abstract [en]

    Destination image has become a crucial topic in tourism studies. However, research has scarcely considered multiple online content sources when studying the image of destinations. This paper examines different types of user-generated content in order to evaluate whether and how this content reflects the evolution of a destination’s image, and its congruence therein. The research focuses on a multi-asset tourist destination, i.e., one which draws different market segments. The results show a relatively high degree in congruence and evolution of the destination’s attractions, but also questions bits of theories on communication congruence as well as attractions’ evolution theories.

    Developer usability testing: A real world example2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The iPhone has thanks to its multitouch interface, size and connectivity change the way we communicate. To fully utilize this technology we can involve users in the development process to help make highly usable software applications. One way to do this we somehow need to get the users to use our systems. What techniques are there to do this? And will they fit our product? Are there any way we can involve the users in the development process of an iPhone application, in this thesis I investigate if this can be accomplished by conducting usability tests with users on an iPhone application. The usability testing gives an insight into how the users work with and adapts to the users interface. The questionnaires given to the participants gave insight into how the users considered the usability and usefulness of the application. This data gave the development much needed data on the application to make it better and more usable. Since earlier research into user involvement have shown a strong connection to usable software and usability testing could be integrated successfully into the development by the single programmer, the conclusion can be drawn that single developer that incorporates usability testing into the development process as a form of user involvement makes more usable software. The usability was tested on an iPhone application built for an American online classified ads website.

    Hur påverkas förtroende av webbdesign?: En kvalitativ intervjustudie om hur en hemsidas design kan påverka det förtroende som en person känner för myndigheten bakom den.2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Användningen av internet har ökat exponentiellt sedan skapandet av The World Wide Web vilket har gjort att användare alltmer använder internet för att utföra sina vardagliga ärenden. Detta har då också börjat ställa krav på funktionell och estetisk design av hemsidor för att användare ska känna sig trygga och ska vilja fortsätta använda hemsidorna. I denna studie undersöks kopplingen mellan webbdesign och känslor av förtroende. Vi delar upp förtroende i 3 underkategorier- kompetens, ärlighet, och välvilja. Även design delas upp i tre kategorier - visuell design, innehållsdesign, och strukturell design. För att identifiera kopplingarna mellan dessa 6 underkategorier så utfördes kvalitativa intervjuer med 4 olika användbarhetsexperter där dessa fick undersöka 4 olika myndigheters hemsidor. Den data som har samlats in har analyserats och jämförts för att hitta samband och likheter i vad som ger en känsla av förtroende men även vad som kan förstöra förtroende och dessa resultat används till slut för att besvara hur designkategorierna påverkar förtroende samt vad som gör vissa hemsidor mer förtroendeingivande. Utifrån denna undersökning kan vi se vissa tydliga samband för dessa frågor. Resultatet visar att alla tre designkategorier är mycket viktiga för att ge användare en känsla av förtroende men av olika anledningar. Alla tre designkategorier är dock viktiga för att göra en myndighetshemsida mer förtroendeingivande. Det visar sig också att avsaknaden av bra kvalité hos en av designkategorier kan medföra mycket försämrad förtroende överlag även om om man gör ett bra jobb med de andra designkategorierna.

    The AI Revolution: A study on the present and future application and value of AI in the context of ERP systems2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Business leaders around the world are expressing equal amounts of excitement and urgency for implementing artificial intelligence (AI) technologies. Yet the upcoming AI revolution is clouded with uncertainties and misconceptions. In this thesis, the business value and application potential of AI were studied in a context of enterprise resource planning (ERP) systems through a case study at a consultancy firm with small- to midsize clients. Three research questions were posed and answered: how can, or do, organizational processes covered by ERP systems benefit from AI, what AI features do customers typically request when ordering ERP systems, and is AI adopted with the purpose of reducing costs or increasing revenue?

    Using a framework for data analysis, multiple organizational processes covered by ERP systems were explored through interviews with ERP experts. The results indicated that small- and midsize companies were still primarily requesting and working to implement basic, incremental AI with the purpose of reducing costs through automations. Future leaders may instead need to implement AI that fundamentally reinvents their business processes, with the purpose of increasing revenue through augmentations. Overall, while some organizational processes have already been improved with AI solutions, many processes have yet to be AI-powered in the ERP solutions sold by the consultancy firm examined in this study. However, the consultants of the firm express great positivity for the untapped potential of AI, and many further AI solutions are being developed.

    Big data: En studie om dess affärsnytta samt dess utmaningar och möjligheter, med fokus på detaljhandeln2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Enormous amounts of data is created and stored today, all the while only a small amount of data is being analysed and used. Big data is a term that has circulated for years, however in recent years its meaning have been increased. More enterprises are starting to open their eyes for big data, while few understand how to actually use it. Some even ask themselves: is there a business benefit? With a focus on the retail industry, we examine whether there is a business benefit with using big data, and above all what challenges and opportunities are connected to it. Terms such as business intelligence and analytics are discussed in the relationship to big data. In this qualitative study, three experts from different enterprises; IBM, Knowit and Exor, have been interviewed. The results from the interviews has been connected to the theory from the literature around the subject, and has been compared in the analysis. All identified challenges and opportunities have been listed, and among the conclusions can the ethical and human factors be seen to have a major importance, and that the business benefits can be dependent of an enterprises’ size and market. The essay is written in Swedish.

    Vägen till DevOps: Implementation i praktiken - en fallstudie hos Centrala Studiestödsnämnden2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    IT-utveckling är ett område präglat av ständig förändring, i form av tekniska medel, innovationer och arbetssätt. Precis som all annan form av produktutveckling varierar det tillvägagångssättet vida mellan organisationer, företag och myndigheter. Inom mjukvaruutveckling har förändringen varit lika snabb som uppkomsten och den har gått från sekventiell traditionella utvecklingsmetoder till flexibla agila. Nu sker det återigen ett nytt skifte till ett mer dynamiskt utvecklingssätt, ämnat att sammanföra och i grunden förändra sättet som teams skapar IT-produkter. I det närmaste en ny filosofi - DevOps. DevOps bygger på principen att utvecklingssidan, “Development”, och drift- och förvaltningssidan, “Operations”, går samman för att skapa ett enhetligt team som är gemensamt ansvariga för hela utvecklings- och förvaltningscykeln. Underlaget som möjliggör detta är en kombination av en stark samarbetskultur, god kommunikation och nyskapande tekniska verktyg. Tillvägagångssätten för att implementera ett sådant brett koncept är många, och implementation av nya arbetssätt är en utmaning för alla organisationer som vågar ligga i framkant. Centrala Studiestödsnämnden, CSN, är en sådan organisation, och en myndighet på väg mot DevOps. Det är inte ett okomplicerat arbete för en myndighet som olikt ett privat företag inte arbetar i vinstsyfte och behöver följa andra lagar och förordningar. Denna studie har genom semi-strukturerade intervjuer och en kompletterande litteraturgenomgång utrett hur en organisation kan implementera DevOps och vilka förutsättningar som finns i nuläget. Resultatet pekar på att CSN som organisation har en god utgångspunkt för en lyckad DevOps-miljö, med några nyckelsteg för att fullfölja en fulländad implementation. Dessa inkluderar faktorer som att minska avståndet mellan Development och Operations, möjliggörandet av nödvändiga tekniska verktyg för automatisering, och en förändring i sin utvecklingsstruktur.

    Towards a Socio-Institutional Ontology for Conceptual Modelling of Information Systems2015In: Advances in Conceptual Modeling: ER 2015 Workshops AHA, CMS, EMoV, MoBID, MORE-BI, MReBA, QMMQ, and SCME, Stockholm, Sweden, October 19-22, 2015, Proceedings / [ed] Jeusfeld, Manfred A., Karlapalem, Kamalakar, Springer International Publishing , 2015, p. 225-235Conference paper (Refereed)
    Abstract [en]

    Most work on ontologies for conceptual modelling is based on the assumption that conceptual models represent a pre-existing reality, which they should faithfully reflect. This paper suggests an ontology for conceptual modelling of institutional domains taking into account also the prescriptive role of conceptual models, thereby supporting the design of information systems. The paper draws on the current ontological discourse in information systems engineering; descriptive vs prescriptive conceptual modelling; socio-materiality in terms of clarifying the relationships be-tween physical and social domains; and ontological differences between (physical) properties and rights. The results of the paper can be used to support conceptual mod-elling in business analysis, in particular requirements elicitation of regulative aspects.

    Using search based methods for beamforming2024Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In accommodating the growing global demand for wireless, Multi-User Multiple-Input and Multiple-Output (MU-MIMO) systems have been identified as the key technology. In such systems, a transmitting basestation serves several users simultaneously, increasing the network capacity. However, sharing the same time-frequency physical resources can cause interference for the simultaneously scheduled users if not moderated properly. One way to mitigate this interference is by directing radio power through the radio channel in specific directions, a method which is called beamforming.

    Following the successful implementation of the AlphaZero algorithm in another radio resource management technique, scheduling, this thesis explores the potential of using a similar search-based method for the beamforming problem, striving towards the ultimate objective of making decisions for scheduling and beamforming jointly. However, as AlphaZero only supports discrete action spaces and the action space of the beamforming problem is continuous, a modification of the algorithm is required. The proposed course of action is to extend AlphaZero into Sampled AlphaZero, using sample-based policy improvement to create an algorithm that is both more scalable for large discrete action spaces and able to handle high dimensional continuous action spaces. To evaluate the performance of the models, test environments were simulated and solved using increasingly larger so-called codebooks, containing predefined beamforming solutions. The results of the Sampled AlphaZero model demonstrated promising performance even for very large codebook sizes, indicating the model's suitability for addressing the beamforming problem in a non-codebook-based context. Furthermore, this thesis explores how states in the search can be represented and preprocessed for the neural network to learn efficiently, demonstrating clear benefits of using a singular value decomposition-based state preprocessing over raw states as input to the neural network.

    Blockchain Technology and Smart Contracts: Privacy-preserving Tools2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this Master's thesis is to explore blockchain technology and smart contracts as a way of building privacy-sensitive applications. The main focus is on a medication plan containing prescriptions, built on a blockchain system of smart contracts. This is an example use case, but the results can be transferred to other ones where sensitive data is being shared and a proof of validity or authentication is needed. First the problem is presented, why medication plans are in need of digitalisation and why blockchain technology is a fitting technology for implementing such an application. Then blockchain technology is explained, since it is a very new and relatively unfamiliar IT construct. Thereafter, a design is proposed for solving the problem. A system of smart contracts was built to prove how such an application can be built, and suggested guidelines for how a blockchain system should be designed to fulfil the requirements that were defined. Finally, a discussion is held regarding the applicability of different blockchain designs to the problem of privacy-handling applications.

    Dark patterns och privacy paradox: En studie om dark patterns i form av FoMO-centrisk designs påverkan på användares datadelning på Instagram2024Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I takt med den ökade användningen av internet och sociala medieplattformar har även dataflödena ökat, och därmed även behovet av att förstå integritetsbeteenden i den digitala miljön. Trots att användare i sådana sammanhang uttrycker oro för den egna integriteten fortsätter de ofta att agera på ett sätt som strider mot deras personliga preferenser, ett fenomen som kallas privacy paradox. FoMO-centrisk design, det vill säga gränssnittsdesign med inslag av dark patterns som manipulerar användaren utifrån känslan av FoMO, har identifierats som en potentiellt bidragande faktor till detta fenomen. Däremot finns det bristande forskning inom detta, och därför är syftet med studien att ta reda på om, och isåfall hur, FoMO-centrisk design på sociala medier kan få användare att motvilligt bete sig på ett mindre integritetsbevarande sätt än vad deras attityder speglar. Detta med Instagram som verktyg genom en kvalitativ forskningsstrategi i form av semistrukturerade intervjuer med användare, samt en förstudie i form av en innehållsanalys av plattformen i syfte att identifiera konkret FoMO-centrisk design. Resultatet visar på att det finns en korrelation mellan FoMO-centrisk design och privacy paradox, där användare agerar på ett sätt som bortser från deras personliga preferenser på grund av designmönstrens påverkan. Studiens resultat bidrar till förståelsen för hur designmönster på sociala medieplattformar kan påverka användares integritetsbeteende och understryker vikten av att ta hänsyn till användares integritetspreferenser i gränssnittsdesign.

    Design of Stand Alone Renewable Power Supply Systems on Futuna Island, Vanuatu2011Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This Master’s Degree project has been performed on behalf of Vanuatu Renewable Energy and Power Association. The purpose of the project was to suggest the design of stand-alone renewable power supply systems on Futuna Island in the Republic of Vanuatu. Futuna is the easternmost island in Vanuatu with a population of about 400 people. The island covers an area of just 13 km2. The proposed sites for power production were the villages of Mission Bay, Matangi, Herald Bay and Iahsoa. In Mission Bay and Matangi the power should be produced by wind turbines and in Herald Bay and Iahsoa, solar modules are proposed.

    The results of the study showed that some parts of Futuna Island can be suitable for wind power production and wind speeds in the order of 5-7 m/s are suggested. However, wind monitoring on the sites are required to estimate the exact potential. Furthermore, the study showed that there is less uncertainty involved with estimating the power output from the solar modules. In addition, solar power proved to be more reliable and less vulnerable to local variations in weather and topography. Solar modules are therefore considered more appropriate for small scale power production on the island, at least until the wind climate is better known.

    The results of the study also showed that proper sizing of battery banks and cables are essential to increase the efficiency and lifetime of the systems. If there are insufficient financial resources in the project, it is therefore recommended in the report to use all resources available to properly size the systems in 1-2 villages rather than to inadequately size the systems in all the villages.
