Today the production time is shortened when components are made with additive manufac- turing and the finished products typically have very few defects. If the components quality is to be validated, it’s done with a Non-destructive testing method. In this thesis a test piece made of Inconel 939, that is used in high temperature application was examined with a non- destructive testing technique (NDT), computed tomography (CT) and with destructive test- ing (DT) by grinding the test piece down to a given position and taking images of the ex- posed surface. The purpose was to validate computed tomography images by doing a two- dimensional correlation between images from CT and DT using MATLAB. Due to tech- nical problems the resulting images were however not showing the same par of the test piece. Therefore the correlation method was instead validated. Modifying a 2D image from CT and running it in the code written in MATLAB could quantify the distortions in the images. Results are presented in figures and in tables. The table shows more detailed in- formation with exact coordinates and what correlation each area has. The figure shows the movements and direction of the changes. The result shows that the method can detect changes and does what was intended. / Idag tillverkas komponenter med additive manufacturing (AM) vilket gör att produktionsti- den blivit kortare och de färdiga produkterna har vanligtvis mycket få fel. Om komponen- ternas kvalitet ska valideras, görs det med en icke-förstörande provningsmetod. I denna avhandling har en provbit av Inconel 939, ett material som lämpar sig för höga temperaturer undersökts med en oförstörande provning teknik (NDT), datortomografi (CT) och förstö- rande provning (DT) genom att slipa sig ner i provbiten till en given position och ta bilder på ytan. Syftet var att validera datortomografibilder genom att göra en tvådimensionell kor- relation mellan bilder från CT och DT med hjälp av MATLAB. På grund av tekniska pro- blem så visar de resulterande bilderna inte samma område. Därför ska korrelationsmetoden valideras. Genom att ändra en 2D-bild från CT och köra den i koden skriven i MATLAB så att den distorderade bilden kan kvantifieras. Resultatet presenteras i figurerna och i tabeller. Tabellen visar mer detaljerat med exakta koordinater och vad varje delområde har för kor- relation. Figuren visar rörelser och riktning av förändringarna. Resultatet visar att metoden kan upptäcka förändringar och göra det som var tänkt.

This thesis explores the perceived enjoyability of Deep Reinforcement learning AI agents (DeepRL agent) that strives towards optimality within the First Person Shooter game Unreal Tournament 2004 (UT2004). The DeepRL agent used in the experiments was created and then trained within this game against the AI agent which comes with the UT2004 game (known here as a trivial UT2004 agent). Through testing the opinions of participants who have played UT2004 deathmatches against both the DeepRL agent and the trivial UT2004agent, the data collected in two participant surveys shows that the DeepRL agent is more enjoyable to face than a trivial UT2004 agent. By striving towards optimality the DeepRL agent developed a behaviour which despite making the DeepRL agent a great deal worse atUT2004 than the trivial UT2004 agent was more enjoyable to face than the trivial UT2004agent. Considering this outcome the data suggests that DeepRL agents in UT2004 which are encouraged to strive towards optimality during training are “enjoyable enough” in order to be considered by game developers to be “good enough” when developing non-trivial opponents for games similar to UT2004. If the development time of a DeepRL agent is reduced or equal in comparison with the development time of a trivial agent then the DeepRL agent could hypothetically be preferable.

This thesis is only available in Swedish, but a translated abstract has been provided to describe how and why it was written, together with a simplification of its results and conclusion. The web has evolved many times over since its inception in the late 80's, and there are now many consortiums and institutions that create and maintain guidelines for how websites should be developed and maintained, which are also represented in international standards, as well as in laws and regulation.  These guidelines are often based on best practices for accessibility on the web, which was also the focal point of this thesis, where institutions for higher education in Sweden were identified as being subject to a lot of the available regulation and also seen as an interesting area to study, as they and their websites are used by visitors of many different backgrounds.  The study for this thesis was built on four different methods of evaluation for accessibility. This combination of methods was also identified as a interesting subject to include in the overall study, with regards to how it could be better than just one or two methods. These methods resulted in four individual results which were analysed and compared between. Regarding the usage of multiple methods it was identified as having a positive impact on the study, as well as what kind and how the results were achieved, but may be unsuitable for larger evaluation projects.  Further, the results and analysis of the accessibility aspects shows that while something is usable, it may still be inaccessible, and vice versa, which was the case for all websites included in the study. The most obvious problems found during the evaluations were regarding document structure and layout, both of which heavily influence how a website is interacted with using either a mouse and keyboard or a screen reader, as well as how its content is perceived.

On the 29th of July 2018, all natural resources that the planet are able to generate that year was used up. This is because of the increasing consumption every year by mankind, which continually move this date forward. If the whole world consumed at the same rate as Sweden does per inhabitant, this date would instead be 4th of April, indicating that our country has major problems that must be solved. In modern times, IT is used everywhere. It can be used in many other sectors than just the IT sector, which means it has a big area of influence and potential to streamline and solve many problems. But the big use of IT also creates problems. Computers affect the environment negatively throughout their whole life cycle from production and use to elimination. According to previous research, the definition of the concept green IT varies among companies which creates uncertainty about how it should be used. Also, it has been noted that several companies have not yet managed to implement their green agendas.  This study aims to find out what concepts Swedish IT companies use to make their business environmentally friendly and sustainable. The purpose of this study is also to find out how these concepts are used, why they are used and what problems and obstacles there is. The question that the study is based on is to understand how Swedish IT companies in reality work with their sustainability initiatives and what advice and guidelines can be drawn from their working methods. To fulfill this, a qualitative survey has been conducted at four IT companies. The interview template was based on four sub-questions into which the research question was divided. Among the people we got in touch with, one of them were an environmental manager and a sustainability coordinator. Finally, an empirical analysis was based on existing theory to answer the research question. The advice and guidelines were placed under the following headings: Internal organization, Techniques and models and Collaboration.

Automated Decision Making is an increasingly growing field in the IT area. Society is leaving more and more decisions to the computers to make. The purpose of this study is to examine what automated decision making is, how and why the swedish authority Försäkringskassan have implemented automated decision making and what the results of their implementation are. For this data was gathered using interviews with people inside Försäkringskassan and the study performed a qualitative approach. To limit the scope of this study it is focused on a branch inside of Försäkringskassan called Barn och Familj. The study gave a deeper understanding of how the systems of automated decision making were used, why an implementation of the systems was necessary and what the future may hold for the branch regarding the development of automated decision making. Further research in this field may be necessary to provide a full-fledged view of Försäkringskassans work with automated decision making. However, this research will significantly shorten the distance to a fully developed understanding. The result of this report is that the branch Barn och Familj uses automated decision-making systems in three different areas. Child allowances, housing allowances and parental insurance are the areas that are fully or partially automated. The conclusion is that the department's systems have been introduced to save time. This is so that administrators can take care of applications that for various reasons require extra resources. The language of this document is swedish.

The purpose of this study was to investigate what opinions people have regarding microchip implant in humans. The report is limited and focused on the risks concerning the microchip implant. To answer the purpose a research question was formulated: “What is the opinion about microchip implants in humans for 18-30-year-old people in Borås, when it comes to risks in their daily life and the society?”. This study is constructed through two studies, a qualitative and a quantitative. The first step in the study was qualitative interviews with six different individuals. These interviews were the basis for the upcoming step, which was the quantitative survey. The quantitative survey was a questionnaire where 100 people were asked. The result showed that the people were not knowledgeable about microchip implants in humans and had a lot of different opinions about the technology. Some saw the risks as a big threat and others saw them as a less of a threat. In the end, the results showed that most of the participants were against microchip implants in humans and would not get chipped. The conclusion showed that the people between ages 18-30, in general, had the same opinions regarding risks that scientific articles and theories mention.

he need for software continues to grow exponentially within every aspect of our society and the demand for intricate software solutions have led to many attempts at improving the development of software. In this overwhelming wave of the positive impact of software on the world, it is easy to dismiss the negative effects software has on the environment. The effects of climate change are becoming more evident day by day and it is crucial to learn the impact of software, and particularly the development of software, on the environment and through which means it can be mitigated.  This research paper aims at identifying methods and practices that can be used to improve existing software development methodologies with regards to sustainability. The software development processes in question are Scrum and Kanban.   The research is done over two phases, the first of which is a literature review that is aimed at identifying existing solutions and guidelines for ensuring sustainability within software development. The second is a set of interviews with developers and managers that work with Scrum and Kanban on daily bases in order to collect information regarding how sustainable their ways of software development are and how they can be improved.  The analysis of the literature review resulted in a taxonomy or a classification of a set of attributes that are recommended to be taken into account during the various phases of software development. These attributes, and in combination with the results of the interviews, yielded a recommended set of best practices that can be used to improve the planning and development phases of software both in Scrum and Kanban with regards to sustainability.

Today, autonomous systems are rapidly being implemented in the daily life. Automation occurs when a task previously performed by a human is replaced by a machine. One of many new techniques is vehicle autonomy. The most contributing factor to incidents in the traffic environment are the human factor, and one predicts that vehicle autonomy can create a safer traffic environment, such as reducing fatal car crashes and severe injuries. However, the advantage of such novel technology can only be created if it is used and the biggest threat is said to be the human resistance of system implementation. The purpose of our study is to get a deeper understanding of users’ perceptions about vehicle autonomy, particularly future travellers. Additionally, we are interested in investigating if their perceptions are based on different aspects, such as gender and/or age. Two separate methods of empirical evidence are used in this study, a literature study and a survey study, which are analysed quantitatively. The study is mainly based on Unified Theory of Acceptance and Use of Technology (UTAUT) and partly the Car Technology Acceptance Model (CTAM) and a proposal of extending the models is submitted. A survey study is implemented with 125 respondents. The result of our study showed an overall positive attitude and that characteristics play an important role in order to accept vehicle autonomy. The result of this study can contribute to a deeper insight into technology acceptance and vehicle autonomy which can be helpful for different actors in the vehicle industry.
