    "Då menar jag inte att man ska få en käftsmäll när man får en käftsmäll": En kvalitativ analys om spelares uppfattning av inlevelse med Head Mounted Displays2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis will study if Head Mounted Displays affect the immersion experienced by gamers while playing video-games, how they expect it to affect the experience and what gamers feel is missing from the technology today to be able to experience total immersion.

    The research is conducted by using a survey and interviews. The main purpose of the survey is to identify which aspects affect the immersion while playing with classic videogame consoles. The in-depth interview show the responses from four different gamer respondents about their experiences and expectations for using Head Mounted Displays today.

    Our study show that Head Mounted Displays do make the user experience higher levels of immersion compared to classic consoles, but if there is a break in presence the reaction is much stronger, since the amount of sensory data that needs to be dealt with is increased. The study also identifies new possible design issues for more seamless experiences with the Head Mounted Displays. For example, using better hand representations, to be able to see and use your own hand in the game, applying wireless technology and solutions for better support for users travel over large areas in game. Summing up, the gamers are optimistic about how Virtual Reality and Head Mounted Displays will affect the gaming industry, they believe it is the future of videogames.

    Prestandajämförelse mellan Amazon EC2 och privat datacenter2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Publika moln har sedan några år tillbaka blivit ett alternativ för olika företag att använda istället för lokala datacenter. Vad publika moln erbjuder är en tjänst som gör det möjligt för företag och privatpersoner att hyra datorkapacitet. Vilket gör att de inte längre behöver spendera pengar på resurser som inte används. Istället för att köpa en stor andel hårdvara och uppskatta hur stor kapacitet som man behöver kan man nu istället så smått börja utöka efter behov eller minska ifall det önskas. Därmed behöver företag inte spendera pengar på hårdvara som inte används eller har för lite datorkapacitet, vilket skulle kunna resultera i att stora batcharbeten inte blir färdiga i tid och i och med det kan företaget förlora potentiella kunder. Potentiella problem  kan dock uppstå när man i ett moln virtualiserar och försöker fördela datorkapacitet mellan flera tusen instanser. Där även skalbarhet inte ska ha några begränsningar, enligt moln-leverantörerna.

    I denna rapport har vi med hjälp av olika benchmarks analyserat prestandan hos den största publika moln-leverantören på marknaden, Amazon, och deras EC2- och S3-tjänster. Vi har genomfört prestandatester på systemminne, MPI och hårddisk I/O. Då dessa är några av de faktorer som hindrar publika moln från att ta över marknaden, enligt artikeln Above The Clouds -  A Berkely View of Cloud Computing [3].  Sedan har vi jämfört resultaten med prestandan på ett privat moln i ett datacenter. Våra resultat indikerar att prestandan på det publika molnet inte är förutsägbar och måste få en ordentlig skjuts för att stora företag ska ha en anledning till att börja använda det.

    Resource analysis of PXE based deployment solutions from Microsoft, Acronis and the FOG project2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In a PXE based deployment an operating system is sent or installed over an IP based net-work, creating a centralised point of control for the management of multiple clients to effectively minimise the workload of the administrator and the total time needed to install operating systems. This project examines the processor, memory and network utilisation of four selected PXE based operating system deployment solutions - Acronis Snap Deploy 5, FOG and two variants of Windows Deployment Services (WDS) - in a part virtualised and part physical environment to determine their differences, scalability and appropriate role.

    The experimental setup consisted of five client computers, a traffic log server, and a server hosting virtual machines onto which the solutions were installed. Measurements were done using Windows Performance Monitor on the main server to poll data from its virtual machines. The time frame of each deployment was determined by the time stamp of the first DHCPDiscover packet sent from a client to the point of time where the network communication between the server and client(s) was complete.

    Acronis and FOG were determined to be much faster than WDS in regards of time, where Acronis adds less time per added client in multicast environments than FOG. The processor utilisation is increased for all systems in multicast scenarios compared to unicast deployments, and Acronis had the highest average and peak processor utilisation throughout the processor measurements. Memory utilisation is a non-issue, and no significant increase was detected between unicast and multicast deployments, or when adding clients to a multicast scenario. The FOG machine running CentOS 6.7 and Linux Integration Services displayed excessive amounts of memory utilisation, a symptom not displayed with LIS inactive. This is determined to be the fault of LIS, and not FOG. Acronis and FOG forward multicast data about four times faster than WDS, which leaves little reason to choose WDS over the other two. Acronis includes some useful proprietary features not found in FOG, and utilises more processor time. The main reason to choose FOG over Acronis is the fact that it is open source and free to download.

    This study is based on problematic in an earlier system in which requests have been made to improve the system to a new one. The new system has become to a dynamic web-based system and implemented with the new development tool Microsoft WebMatrix. Microsoft says that developing websites with WebMatrix has never been easier, a statement which is considered as vague.The purpose of the study is to analyze this tool and its new technologies, then result if the statement according to Microsoft is partially true or not, if WebMatrix and its new technologies perceived simple to use. The study also describes the underlying problem and which techniques that have been implemented in the new system using WebMatrix. The purpose of the previously and the new system is service planning of the staff within the organization University West in Trollhättan. The goal is to simplify and improve the service planning.The study and implementation of the system has resulted in that WebMatrix perceived as simple and has a content of useful techniques that contribute to an effective development. The new system which has been created has resulted in being a positive solution which is simplifying service planning. The system contains only functionality that is relevant, have a better overview and a structure that makes it easier to administer. Unlike the previous system data is stored in a database, which has contributed to a very positive impression of the system's users, given the common availability.

    Abstract [en]

    This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.

    Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters. The measurement done to the GPS speed calculating application showed that the application was more accurate than the speedometer in the test car.

    The result of this thesis was that if all the parts were to be put together to a single application the maximum speed that it could be used with some functionality was 13,8 kilometers/hour assuming that the car ahead is at a standstill and the camera on the mobile phone is in a straight line from the license plate.

    The dynamics of interaction: exploring a living lab innovation process from a community of practice perspective2011In: Proceedings of Pacific Asia Conference on Information Systems (PACIS) 2011, Association for Information Systems, 2011, article id 85Conference paper (Refereed)
    Abstract [en]

    This paper is based on a living lab project, which is an open, user-centric, innovation approach, where several actors from industry, user groups and academia are involved. The research question is: How can interaction dynamics be understood in a living lab innovation process? We applied an action-oriented research approach, where the empirical results are from The Find Project (TFP), which aim is to customize an ICT product based on the needs of a user group. The findings are analyzed from a community of practice perspective where three different communities, i) researchers from Halmstad Living Lab (HLL), ii) ICT developers (ICTD) and iii) next of kin of demented elderly persons (NOKD), represented the unit of analysis. We identified situations and activities that played a vital role for the innovation process in terms of boundary interaction dynamics. The contribution of our research to innovation theory is a combination and further exploration of the boundary spanning and communities of practice theories. We have developed a conceptual model describing the dynamics in boundary interactions of an ICT innovation process with regard to boundary objects-inuse and brokering. The conceptual model highlights two different levels of brokering: i) inner-level brokering and ii) outer-level brokering.

    Abstract [en]

    This paper is based on studies of a living lab process, which is an open, user-centric, innovation approach, where several actors from industry, user groups and academia are involved. We aim to describe and analyze the dynamics in an innovation boundary context based on a living lab process. An action-oriented research approach was applied and the empirical results are from The Find Project (TFP), with the aim of customizing an ICT product based on the needs of a user group. The findings are analyzed from a community of practice perspective where the three different communities i) researchers from Halmstad Living Lab (HLL), ii) ICT developers (ICTD), and iii) next of kin's to demented elderly persons (NOKD) represented the units of analysis. The analysis identified several boundary situations that played a vital role for the innovation process. The contribution of our research to innovation theory is a process model describing the dynamics in an innovation boundary context with regard to boundary objects-in-use as well as to brokering. The research highlights two different levels of brokering: i) product/service brokering; and ii) process brokering.

    Boundary dialogues in user-centric innovation2012In: 18th Americas Conference on Information Systems 2012, AMCIS 2012, Seattle, WA, 2012, Vol. 4, p. 2910-2919Conference paper (Refereed)
    Abstract [en]

    This paper is based on a user-centric innovation project, Free2Ride, which is seen as an example of community interaction that overcomes boundaries. Free2Ride aimed at developing a piece of ICT safety equipment consisting of a sender (on the horse) and a receiver (application in a smartphone) to be used by equestrian club members during their everyday riding activities. We will answer the research question of what the characteristics of a boundary dialogue in user-centric innovation activities are. The aim of the paper is to propose a model describing the characteristics of boundary dialogue in user-centric innovation that involve different communities of practices such as ICT developers, users and researchers. We applied a combination of research approaches consisting of action research and engaged scholarship approach. The theoretical framework for analyzing our findings is communities of practices with a specific interest in boundary spanning and learning dialogues. Our contribution is a model describing the characteristics of boundary dialogues in user-centric innovation. An important element of that model is the mental wandering, inwards and outwards, by core members in a community. We discuss the temporal as well as the symbolic nature of the mental wandering during the boundary dialogue in user-centric innovation activities. © (2012) by the AIS/ICIS Administrative Office All rights reserved.

    “Men det står ju rekommenderat, då tar jag väl det”: En kvalitativ studie om nudging i e-handelns kassa2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years, consumption in e-commerce has increased with more purchases being made in down payment. The consequences of that being more citizens in Sweden, and especially young adults, applying for debt restructuring. To overcome the problem, the government made new legislation that has been integrated into the digital cash register, where paying methods that involve credit are no longer to be promoted as a default. The legislation is based on Nudging technology, where the aim is to push consumers towards making more well-thought-out decisions, without limiting the free will, in hope that more consumers will make better choices for their economy. The purpose of this study is to examine how consumers act in digital cash registers, to see if nudging can be applied and influence the choice of payment method. The study was implemented by using qualitative research methods where two semi-structured focus group interviews were implemented. Consumers were invited to talk about their own experience and discuss the visual examples of digital cash registers that were presented before them. The result of the study shows that consumption in e-commerce is carried through mostly due to flexibility, that a payment method that is default is not as effective at check-out at the digital cash register, but that personal preferences, experiences, and trust play a great role in choosing payment methods. The result also implies that the consumers were unfamiliar with nudging, were positive about the new legislation but thought that if nudging is to be used, they should be simple and transparent. Finally, the conclusion that is drawn: nudging the digital cash registers would have had a greater effect if the information was clear about why the choice was the default or recommended, in order to increase motivation and reduce the risk of manipulation among those who were exposed to nudging.

    Data and Information Handling in Assembly Information Systems: A Current State Analysis2017In: Procedia Manufacturing, E-ISSN 2351-9789, Vol. 11, p. 2099-2106Article in journal (Refereed)
    Abstract [en]

    Products become more complex as the general technology development reaches new levels. These new technologies enable manufacturing companies to offer better products with new functionalities to their customers. Complex products require adequate manufacturing systems to cope with changing product requirements. In general, manufacturing of this type of products entails complex structured and rigid IT systems. Due to the system’s complexity and comprehensive structure, it becomes challenging to optimize the information flow. There are improvement potentials in how such systems could be better structured to meet the demands in complex manufacturing situations. This is particularly true for the vehicle manufacturing industry where growth in many cases have occurred through acquisitions, resulting in increased levels of legacy IT systems. Additionally, this industry is characterized by high levels of product variety which contribute to the complexity of the manufacturing processes. In manual assembly of these products, operations are dependent on high quality assembly work instructions to cope with the complex assembly situations. This paper presents a current state analysis of data and information handling in assembly information systems at multiple production sites at a case company manufacturing heavy vehicles. On basis of a certain set of characterizing manual assembly tasks for truck, engine and transmission assembly, this work focuses on identifying what data and information that is made available to operators in terms of assembly work instructions and the importance of such data and information. This work aims to identify gaps in the information flow between manufacturing engineering and shop floor operations. © 2017 The Authors

    Lärarledarskap på distans: utmaningar och möjligheter i teknikmedierad undervisning2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Covid-19 pandemic caused a series of consequences for the educational environment. Teachers who normally taught in traditional physical classrooms now had to move to digital online classrooms thus they had to change their ways of teaching to fit the new environment. The purpose of this thesis is to identify how the distance education form affected the teacher leadership. In order to identify and research the possibilities and challenges that the digitally mediated education brought to teacher leadership, eleven university teachers who had taught in classrooms before and during the pandemic were interviewed. Two main dimensions were identified from the empirical data and were analysed using athematic analysis. The first theme is being the teachers leadership duties, the second being the effects of forced distance education. The teachers leadership duties consisted of five sub-themes: individualisation, planning, control, motivation and grouping. The effects of forced distance education consists of three sub-themes: student contact, technology and psychosocial wellbeing. Conclusively all dimensions were affected negatively by the enforced distance education whereas the challenges far outweigh the possibilities. The primary factors that affected teacher leadership negatively were the loss of control and student contact. These factors are the base of all of the other themes and they are all affected negatively when the aforementioned two are lost.

    Vill ni betala för min film?: En kvalitativ fallstudie kring framgångsfaktorer i crowdfundingkampanjer2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Crowdfunding is a concept that is growing among entrepreneurs. Crowdfunding involves using small donations from many people able to finance their product or project. Kickstarter is a crowdfundingplattform where you can create campaigns to raise money. If the campaign should be seen as successful need a financial target that met. Our investigation involves identifying factors that are important for the success of their campaign. We also want to investigate how these factors are interrelated and how the description of the project affects people to donate.

    The survey found that personal and targeted languages to different types of genres is important to motivate people to want to donate. Use of images to enhance text is a factor that proved to be effective. Moreover, it is important to work creatively with rewards given to people who donate. These factors motivate a person to both donate money to the campaign, but also spread it to other social media, which is crucial for the success of the campaign.

    Behov av dokumentation inom agila projekt vid systemförvaltning: En fallstudie2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study focuses on the documentation in the management of ERP- (Enterprise Resource Planning) systems and the challenges that exist around documentation in agile methods. The study provides knowledge about the needs for documentation in agile projects for system maintenance and the risks associated with a lack of documentation in the administration. A qualitative approach has been used by a case study. The study's conclusions are based on ob-servations, interviews and document analysis. Agile methods do not require as much docu-mentation of tasks and are based on personal collaborations between operators in the system. The study's final results show that the documentation cannot be excluded, but it should be used where it fits. If documentation support human interaction, rather than to replace it, can it still can be in line with agile development principles. There is a general consensus that that a major drawback of Agile methodologies is a loss of undocumented knowledge. Because doc-umentation is compromised when applying agile methods, important knowledge is lost during and after system development. Many companies are embracing Agile projects are told that they should not be document anything, without relying on open communication going on. People often misunderstand agile methods. Policies and practices for Agile methodologies introduced in organizations but not implemented fully.

    Abstract [en]

    The fact that actors with the aim of generating targeted ads track internet users via cookies on the web can be considered problematic when it comes to privacy. In some contexts, the use of cookies can also make IT security measures more important to take. With the introduction of new software technologies, today's useful anti-tracking measures may become redundant, and internet users privacy is thus exposed to new risks. In this work, internet users opinions, awareness and tendency to take four measures against tracking were investigated. What security measures are usually taken were also studied, as well as internet users perceived concern and apprehension about their privacy online. A quantitatively oriented survey was carried out, which included 17 questions with predetermined answer options. The survey was designed via Google Forms, and a digitally generated link was sent out via Facebook Messenger and several other digital platforms. The response data was analyzed using Google Forms and Excel. In total, 43 survey responses were collected, and the results showed a reasonably high level of concern regarding privacy among surveyed internet users. An even greater concern could also be demonstrated among the internet users who took any of the four anti-tracking measures specified in this study. These respondents were also found to be more aware of the functionality and purpose that cookies serve than other participants in the study. Similar to another study, it could also be demonstrated that internet users who used software to block ads to a greater extent took other measures against tracking online. Almost all surveyed internet users took one or more security measures on their devices, and no problem regarding a lack of security awareness could be demonstrated. In the relatively near future, third-party cookies, and thus also cookie notices on webpages on the internet, may be phased out in favor of browser-integrated software technologies. Almost half of the participants in the study were found to be positively or cautiously positive about this, despite the fact that it will likely lead to reduced opportunities for them to avoid tracking and targeted advertising on the internet. Similar to a previous study, it is emphasized that the EU statutory principle of informed consent via cookie notices has shortcomings, and it is assessed that these shortcomings have not been fully overcome. It is concluded that some internet users are likely not satisfied with its practical implementation.

    Abstract [en]

    That the knowledge which is required for a web developer is shifting with time is absolute. The development of both internet services and hardware is rapidly advancing, and with that theprerequisites of web pages and web apps increases. Qualities such as functionality, performance, safety, production time and simplicity are sought after. Through the use of frameworks and content management systems these qualities are acquired. In this work, we conduct an empirical study to find out what knowledge in addition to the most basic ones that employers are looking for when hiring a web developer, by collecting data from active job advertisements and also by interviewing web developers. The result from our data collection shows that the most requested programming language is C#, the framework is React, the content management system is WordPress and the database knowledge is SQL. PHP is also in high demand. Our analysis shows that traditional web development, that is, using only HTML, CSS and JavaScript is no longer sufficient. Nowadays, broader knowledge is needed.

    Study of the most important opportunities and obstacles for the development of smart homes in Kurdistan2021Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Kurdistan region of Iraq has special problems and circumstances, which could use an improvement by new smart home technologies. The region also has a unique situation when it comes to the economy, investing opportunities, the government´s engagement, and attitudes towards new technologies. One of the main issues in the region is that the electricity is unreliable and the national electricity grids cannot provide enough electricity. Because of this, there are privately owned diesel generators in each neighborhood that are unsafe, bad for the environment, and expensive for people to use. Thus, the main focus of this study has come to be about how smart home technologies can be a part of the solution to the electricity consumption and distribution problems, and what the government can do to urge this development. In order to examine this, the earlier research on the subject is studied, looked into what the government is doing related to smart home technologies, and conducted interviews with experts within construction and energy, active in Kurdistan, to find out what the main opportunities and obstacles for smart home technology development in the region are. The result shows that smart home technology could be beneficial, especially when it comes to energy efficiency since the current problems with electricity in the region. The interview respondents meant that an expansion of the technology should be done by the government. They also saw that maybe they need more knowledge about the technology to understand the benefits and be willing to enforce the development at a larger scale, even though they have made some accomplishments already. Most of the interviewees also mentioned the combination of the technology with solar energy, pointed out as a good opportunity in Kurdistan due to the geographical situation. When it comes to other features of smart home technology, it seems that most people see it as an unnecessary luxury and therefore do not consider it very useful.

    he purpose of the thesis is to find out the differences between photorealistic computer-generated image and photographed images for marketing purposes, and to find out the advantages and disadvantages of using photorealistic computer-generated image in the field of product visualization for marketing purposes. We also investigate whether there are any moral issues with using photorealistic computer-generated images for marketing purposes. The survey was conducted through a qualitative method through interviews of companies and individuals who use or have used photorealistic computer-generated still images for marketing purposes, where the focus was on the participants' experiences and opinions. The essay highlights six methods for achieving a photorealistic computer-generated image, which relates to the interpretation of Lee and Shim (2012) which deals with the factors that make a computer-generated image photorealistic. The theoretical part of the essay aims to create a greater understanding of the field of photorealistic image, and presents differences between photographs and computer-generated images. The results of the study show that there are several advantages for companies to use photorealistic computer-generated images for marketing purposes, while there are areas where photography with a camera can be a better method.

    Molntjänsters implikationer för hållbar transformation: En studie med fokus på sociala, ekologiska och tekniska dimensioner för hållbarhet hos organisationer2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Nowadays sustainable development and sustainability related problems have a central role in the modern world. Actors around the world are trying to do their part - this also includes organizations. The transformation from today's way of work to more sustainable work practices is called a sustainable transformation. One of the biggest information technologies of today is cloud services. The technology has many benefits towards the environment. Implementing a Sustainable transformation is a challenging task, but cloud services can be used to facilitate the transformation for organizations.

    Aim: The aim of the study is to investigate cloud services and its social, environmental and technical implications towards sustainable transformations of organizations. In other words, how cloud services affect organizations in their journey to become more sustainable. 

    Method: The study takes a qualitative research approach to gain knowledge of people's interpretations, opinions, and experiences about cloud services and sustainability. The method consists of an initial literature study and individual semi-structured interviews. The selection consisted of seven respondents, four from Microsoft and three from one of their customer organizations.

    Result: The result shows that there are several factors that affect sustainability in organizations. Organizations that use Azure as a platform are affected by technical, social, and ecological implications. There are two different aspects of the result. The first one is the implications that come when you use Azure and its services. The other one is the data centres and their implications on the cloud services and organizations. There are four themes that emerge from the result, data centres meaning for technical sustainability, the importance of cloud services for ecological sustainability, visualization of data and the importance of cloud services for social sustainability.

    Animerad TV-vinjett: utsmyckning eller genre? En studie i animerad TV-vinjett2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today, the TV vignette is considered an embellishment to a TV program, despite its broad audiences and unique appearance. We wanted to find out if the television vignette has some common features and conventions but also find out how it relates to genre.We used a case study where we analyzed ten vignettes that we chose from certain criteria. We used a model based on image analysis that we modified to fit our needs. The main parts of each model consisted semiotics, imagery, dramaturgy and sound.We also made a couple of interviews with people who are active or used to work with vignettes. As a result we discovered that the television vignettes consist of certain conventions and that the vignette will not be considered as an independent genre, until the public has accepted it. However, we found that the vignette has common features and conventions that could fit into the established art form Motion Graphics. We see, however, that the vignette has the potential, thanks to digitization, to evolve and become a kind of its own.Today, the TV vignette is considered an embellishment to a TV program, despite its broad audiences and unique appearance.

    Yttre faktorers påverkan på utvecklingen av aktiva säkerhetssystem i bilar: En kvalitativ undersökning2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Active vehicle safety systems are becoming a standard in new cars and these systems are expected to protect us and make our driving experience easier but more importantly safer. To develop and test these safety systems external factors needs to be considered in the development process. These external factors are affecting more than just the development, they determine how the systems will affect the traffic as a whole.

    The purpose of this thesis is primarily to study how Transportstyrelsen may reach its "Zero vision" goal with the help of active safety systems in cars. At the same time, we will examine how these systems function as well as identifying and examining some external factors that affect the development and functionality of these systems. The thesis is a qualitative study on how Transportstyrelsen may reach the "Zero vision" goal with the help of active vehicle safety systems and how external factors affect these. To answer the thesis´ two research questions six semi-structured interviews were carried out as well as reviewing previous literature and their research results.

    The result proved how external factors are a major part of the development of the active traffic safety systems and as such a major factor when it comes to how Transportstyrelsen will reach its "Zero vision" goal.

    Use-centred design of medical and healthcare technology: a pilot study of field tests as a development tool2011In: International Journal of Biomedical Engineering and Technology, ISSN 1752-6418, Vol. 5, no 1, p. 11-28Article in journal (Refereed)
    Abstract [en]

    The purpose of the project has been to develop a process through which users, staff as well as patients, can be involved in field evaluations of medical and healthcare technology. Interviews with different stakeholders and the experiences from four case studies have led to the following conclusions. Users have the potential to act as active evaluators rather than passive subjects or participants only. However, user involvement in field evaluations must be supported by a formation of facilitators or 'door openers' to the healthcare organisation, moderators enhancing the dialogue between developers and users, and mentors for the users acting as evaluators

    Lösenord och lösenordshantering på internet2022Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    Passwords are something that’s being used daily which results in a lot more passwords that’s being used on many different platforms. Secure passwords and management these are of the utmost importance. One innovation that’s getting more and more attention is password managers and could possibly be an easier way of managing passwords for all different platforms.

    In this degree project there will be a survey where the purpose is to find out what the participants think of passwords and how they handle and store them.

    The survey is investigating people within different generations and if they have a background in IT /Cybersecurity. Our thought would be that older people would have worse habits when it comes to passwords and management, and that people with a background in IT/Cybersecurity would have better habits than people without experience. How long passwords do they have? How many different passwords do they have? How does people store all these passwords that are in use? These are a few of the questions asked to the around 100 participants.

    After consolidation all the answers, we analysed all the answers and put together a presentation. We found out that there is not much of a difference through the generations of age, as well as participants with a background in IT/Cybersecurity turned out to be not much better than a person that doesn’t have a background within the field. It all comes down to personal preference.

    Känslor som verktyg i reklam: En kvalitativ studie om hur individers känslor och beteenden påverkas av digital storytelling i ideella organisationer2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Digital Storytelling is a concept described as a communication process where people can convey their message in the form of narrative stories. In conjunction with the modernization, these stories have been used in new ways. Digital storytelling enables companies to shape their ideas by giving recipients an experience that can evoke both emotions and new thoughts. The purpose of this study is to create an understanding of how digital storytelling can be used as a marketing tool in non-profit organizations. The purpose will be achieved by identifying the main factors that affect the recipients emotionally in one of “Cancerfonden” commercials. This was done with the help of semi-structured interviews, where seven respondents were selected with variation in age and gender.

    Selected theoretical frameworks contain theories about digital storytelling, the structure of advertising and how it affects the recipient. Significant parts of storytelling are capturing attention, providing experiences, evoking emotions and creating pattern recognition with the help of a chosen narrative structure. By using these parts, successful advertising can give rise to a more favorable and deeper relationship between recipients and companies. This study concludes that three factors are significant for how affected the recipient is by digital storytelling in commercials; personal recognition, feeling of self wellbeing and trust. This study concludes that digital storytelling is more effective when non-profit organizations gets to know its target group more deeply and can identify these factors above.

    Införande av distansmöte via video: Vid samordnad vård- och omsorgspanering i Västra Götalandsregionen2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Region Västra Götaland has introduced a video implementation meeting on health and long-term care planning for released patients. This is a tripartite cooperation in which the municipality, hospital and primary care are supposed to participate. In this study, we delimit ourselves to primary care and the implications of this technology at their part. The initial thought is that you should make use of distance meetings via video on every occasion where the opportunity to do so exists, but we can see that the utilization rate today is at a low level. This raises questions. We have therefore asked ourselves how the change process had an impact on usage. We have also asked ourselves what the flaws were and what kind of resistance arose against the change. In order to answer the questions, we have been using the interview method and because we want to examine the change process, we focused on interviewing management lines and managers that have been involved in the change. In our theoretical framework, we have been using Kurt Lewin’s recognized model of change, Arnfalk’s theory of distance meetings and how it should be introduced, the “caught in the middle” role of middle managers in the public sector, and theories relevant to resistance. Theories in relation with the empirical results made it possible for us to answer the questions.

    Since this was qualitative study, the results are presented in the form of the summary of respondents' quotes. Secondary data were taken from the public documents that had been published by the region Västra Götaland. Finally, we tested our empiricism against, in particular, Lewin's change theory and concluded that the implementation has not gone past the first, so-called unfreezing phase. Consequently, the change affected the use negatively as they have not succeeded in destabilizing everyday activities and change attitudes. Information and communication have not communicated properly down the management line and middle managers have, because of this, failed to involve their staff. Distance meetings is a new process for primary care where the situation is already strained, which means that middle managers end up "caught in the middle” and not showing enough commitment and desire for change. One should always in a process of change, regardless size, ensuring that everyone involved understands the importance of the change before starting working on it, otherwise the resistance will occur.

    A Proof-of-concept for Bot based DeFi trading2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Decentralized financial (DeFi) is the new financial trend that launched a few years ago. This market attracts a lot of Investors' capital to it. Crypto currencies and blockchain is the core of DeFi market where the investors and traders try to get opportunities of Crypto currencies price volatility in order to make profits. However, this volatility in the prices can lead to economic risk for the traders.

    The purpose of this thesis is to design and implement a proof-of-concept for a bot-based trading system that works on the decentralized finance (DeFi) ecosystem on Binance Smart Chain, in order to gather the token pairs prices and take advantage from the trading strategies to place, sell and buy orders automatically. This system aims to give permission for the bot to be able to access the owner’stokens in Metamask digital wallet. Furthermore, it aims to make the bot able to run and interact with the users' wallet 24/7 regardless if the users are online or not.

    The results of designing and implementing this proof-of-concept shows that the system meets the requirements. It is possible to build an automated trading system on the decentralized finance market. However, there are some financial and trust issues to be solved before it would be feasible launched on the market.

    Abstract [en]

    In this thesis we are researching the development of storytelling in games, in particular independent game productions. By looking at the already established development in the American cinema we compare the mainstream and independent productions to modern societies' producer patterns in games.We explore differences and similarities of storytelling in mainstream-and independent games by making a comparative analysis of two games: the mainstream production L.ANoire, 2011, and the independent production Journey,2012. By using theories such as Aristotle's three act structure, mise-en-scen and character development we are able to get an overall impression of the aspects storytelling has in these games. To further strengthen our analysis we conducted two interviews with established game developers. One of them has an extensive history of working with mainstream productions and the other is an independent game developer with a successful production history.We manage to argue for the impact independent game development has on the mainstream productions in regard to storytelling. Both the interviews and analysis show that independent game productions are using storytelling in a much more experimental manner, adapting it from the American cinema to the medium of games. However, wefailed to give a clear representation to how storytelling, as a new language, is developing in games.

    Abstract [en]

    This study explores learning when professionals return to education and use their professional work experience to fulfil their study objectives. The research question is: How do students learn from experiences in two contexts-a master’s course at a university and their organisations of employment-by attending a blended learning course? The study builds on Engeström’s (2001) expansive learning model of two interacting activity systems, namely, the students’ master’s degree programme and their professional workplaces. As the study context is an online learning environment it follows a "netnographic" approach. The findings show that the students integrated requirements from their university studies with interventions in their professional work situations. The online learning environment enabled reification of reflections which the students could use later in their study and supported them to become more skilled professionals and influencers in their organisations of employment. © Universitetsforlaget.

    Rethinking expansive learning: Experience from an educational design supporting authors in practice2015Conference paper (Other academic)
    Abstract [en]

    This paper analyses an online community of master's students taking a course in ICT and organisational learning. The students initiated and facilitated an educational design for organisational learning called Proactive Review in the organisation where they are employed. By using an online discussion forum on Google groups, they created new ways of reflecting and learning. We used netnography to select qualitative postings from the online community and expansive learning concepts for data analysis. The findings show how students changed practices of organisational learning in their professional organisation and how they developed their identity to become more skilled practitioners. We discuss the effects of the written discussions and reflections on the students' endeavour to become authors in practice. Our contribution to the research consists of considerations of changing the spoken word to the written word, which lacks spontaneity but supports equality among students.

    VR-designers arbete med tillgänglighet inom virtuella upplevelser2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Virtual Reality (VR) is an extensive field where significant development has been made. A critical aspect of the user experiences is still relatively unexplored, the accessibility. How VR designers can work to make their experiences more accessible becomes an important part regarding the development of the technology and the inclusion of users with disabilities. Today, there is no known, structured study about how VR designers in Sweden work practically with accessibility within virtual experiences. The purpose of this study is therefore to create knowledge about how designers within the VR industry work with accessibility in the design of virtual experiences. In this study we conducted a survey, which focused on factors that influence the work with accessibility in VR, and six deepening interviews. The result of the survey showed differences within occupational groups, where visual VR designers work more with accessibility than other occupational groups. The result of the interviews revealed tendencies that VR designers’ point of view and definition considering accessibility, affected which people with disabilities that were included in their design process. Establishing generic guidelines or tools can support VR designers' work with accessibility, but these do not make the virtual experiences accessible. Some kind of collaborative work between designers and users with disabilities is needed to ensure accessible VR experiences.

    Hi, I am the new digital co-worker: A qualitative study on employees within the public sector’s expectations and experiences of implementing AI chatbots2021Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Chatbots are becoming increasingly common within both private and public sectors as they are implemented for organizations to provide service at any time. Within related research on the topic, the focus lies on the private sector and chatbot users, while the research on how chatbot implementation may affect the employees within the public sector is lacking. The focus of this thesis is therefore to provide more information about chatbot implementation within the public sector. More specifically, to understand how the employees expect and experience that the implementation of chatbots can affect them in their work and ways to communicate information. 

    In this study, eight semi-structured interviews with a duration of one hour each were conducted, where the interviewees were employees in municipalities and universities who are working with chatbot implementation. The results show that the interviewees expect that there will be a decreased workload and increased time to work on more complex tasks. However, the time that is liberated because of the chatbot needs to be reinvested into its upkeep, and the interviewees experience that new tasks are added to fill that time, indicating that their expectations are unfulfilled. 

    The results also show that the interviewees expect the chatbot to increase their availability and that it will be a new, less formal way to communicate information. It is experienced that people can contact them any time through the chatbot. They experience that the chatbot uses a simple language to communicate information and that it presents information like it would be presented by a human.

    Usability Evaluation of CityAirSim: An Educational Virtual Reality Application2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The CityAirSim VR application presents a promising platform for urban air quality visualisation, but its UI/UX design can significantly impact user experience and usability. This usability evaluation study employed a mixed-methods approach, utilising usability tests, semi-structured interviews, and the User Experience Questionnaire (UEQ) to evaluate the application. As part of the evaluation, a new 3D menu with a direct manipulation interaction method was developed and compared to the existing 2D menuwith point-and-click interaction as part of the evaluation. Thirteen participants participated in the evaluation, highlighting effective aspects suchas ease of use, visibility, interactiveness, and feedback for both menus. However, issuessuch as visibility and visual design improvements were identified for both menus. Suggestions include improving menu state indicators and providing tutorials for better learnability. As for the preference between the menus, a majority of participants (n=11,85%) preferred the 3D menu. The UEQ and interview results indicate that the hedonic factors significantly influenced the preference between the 3D and 2D menus

    Co-Creators of Scope of Action: An exploration of the dynamic relationship between people, IT, and work in a nursing context2006Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Information Technology (IT) is today widespread in our work places, in our spare time and in our society overall. Implementations of IT in organizations come with high expectations on effectiveness, revenue, smoother work processes and so on. However, this simplified view on IT ignores the fact that it is the IT usage rather than the IT artifact per se that in the end decides the effect of an implementation of IT. Although the IT artifact certainly has been designed to support certain tasks and processes, the success or failure of the Information System (IS) in the end depends on the individuals' actions, which ultimately depend on their perceptions and interpretations of the IS. Thus, when technology is being implemented and becomes an IS in use, it becomes a part of work, and as such more of a social system than a technological one.

    The actual result of a design process does not solely consist of things or artifacts, but above all changed action patterns for the users. From this follows that we must consider design of artifacts as something more than merely the constructing of actual objects with functions and properties that are easily measured. Rather, a large part of all design activities has to do with design of conceivable social milieus, not artifacts. Thus, design may be defined as the suggesting and establishing of scope of action. The concept scope of action aims at describing the fact that the design of, and consequently the implementation of, a specific IT artifact always aims at creating a certain scope of action; some actions are made easier, others are made more difficult or even impossible. This scope of action has to some extent been deliberately designed, but these changes may on the other hand also be undesired and not predicted in advance. The complexity of this phenomenon is great and hard to grasp in advance. However, this does not mean that we can allow ourselves to ignore exploring this phenomenon more deeply. On the contrary, with a usage perspective on IS success or failure, scope of action becomes very important.

    Although the term scope of action may seem a rather intuitive concept, we need more concrete knowledge about its character in order to be able to understand IT usage, both when designing a new IT artifact and when studying or evaluating IT. Thus, our intuitive understanding of the concept needs to be complemented with theory on the ‘constituents’ and effects of this phenomenon. For this purpose, in this thesis nurses’ use of the Electronic Patient record (EPR) is being explored in order to gain an empirically derived understanding of the character of scope of action.

    The research findings highlight the emergent character of scope of action. It is obvious that an individual’s scope of action is not being created on one occasion, and above all not only by the IT artifact. Various co- creators such as the IT artifact, the usage and the social context create and re-create scope of action. Also, how the individual interprets and understands the IT artifact in IT usage will influence her scope of action. This since sensemaking and learning processes on both a personal and organizational level take place that are co-creators of the individual’s scope of action, at the same time as the individual’s knowledge and previous sensemaking and learning influences her use of the IT artifact.

    Thus, reasoning, thinking, learning, and the IT artifact co-evolve over time in adaptation and appropriation processes. This means that IT as a mediational means constitutes an important co-creator of scope of action. From this also follows that work integrated learning is an important co- creator of scope of action when using IT in a work setting, at the same time as work integrated learning is being influenced by the individual’s scope of action.

    Finally, in order to understand how scope of action emerges in use, merely focusing on structures is insufficient. Scope of action emerges as a product of interplay between complex processes involving artifacts, usage and context. This means that the user’s scope of action is co-created by both static structures as well as dynamic processes relating to the IT artifact, the organization, and the work practice. Thus, the IT artifact, and subsequently scope of action, must be must be understood in relation to the multi-aspectual context of which it is a part instead of merely in relation to the properties of the IT artifact per se.

    Cybersäkerhet under en pandemi –påverkad av distansarbete och trenden BYOD2022Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [sv]

    Efter att pandemin slagit hårt i vårt samhälle, skede en del av förnedringar gällande levnadsvanor, både i privatliv och i arbetsliv. Många företag har, där tjänsterna hade tillåtit detta, gått över till distansarbete vilket ställde höga krav utifrån cybersäkerhets perspektiv.

    Denna uppsats undersöker pandemins inverkan på cybersäkerhet och hur cyberkriminella aktörer respektive organisationer hare agerat. Studien tar upp även dem risker som tillkommer med distansarbeten samt fenomenet ”Bring your own device” (BYOD).

    En kvalitativ datainsamling tillsammans med bred litteraturforskning ställs som grund för denna studie. Intervju respondenter som har IT tjänster inom kommunen har besvarat på en del frågor kring hur de upplever och anser att pandemin hade påverkat cybersäkerhet, samt deras upplevelse av tillkommande cyberhot och själva distansarbeten. Det har diskuterats även dem åtgärderna som har tagits in för att förhindra nya kommande cyberhot och förstärka cybersäkerheten.

    Resultaten av studie visar att cyberhot har ökat på vissa ställen och att detta har präglats mest kring Covid-19 relaterade webtjänster och e-post. Trots detta resultat av intervju ger en positiv återkoppling gällande cybersäkerhet där riktlinjer från diverse myndigheter har använts som grund för utformning av säkerhetspolicy som tillsammans med olika säkerhetsverktyghar bidragit till en ökad cybersäkerhet.

    Linux vs Windows: Spelprestanda2021Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    This project is examining the differences in gaming performance in Linux and Proton compared to Windows. The goal is to get a better view of differences in performance between the different operating systems. Performance is measured in average FPS (an average of how many frames is shown per second) and 1% lows (the worst performance one can expect). In addition the hardware usage on graphics card, processor and RAM ismonitored and documented during the tests. The tests were conducted on fresh installed versions of each operating system, on the same computer and with the same graphics settings on each game. The results show that generally Windows has a higher average FPS(3 out of 4 titles) while Linux has higher 1% lows (3 out of 4 titles). On the hardware results an even usage can be seen but with each title there were components that stuck out from the rest. The tests show that a good Linux port can perform as good as and even better than Windows.

    Point of View: The Impact of Background Conditions on Distinguishability of Visualised Data in Detailed Virtual Environments2021Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Data visualisation in a virtual environment (VE) opens up new ways of presenting data and makes it possible for the observer to explore data in an immersive way. However, it also comes with a number of challenges. One of these challenges is data distinguishability. The data needs to be distinguishable against the background, but in a VE where the user can move around and observe the data from different perspectives, the backdrop will be constantly changing. This thesis studies this challenge and contributes knowledge to current research about data visualisation in VEs. The research question When in a detailed virtual environment, what impact does the varying background have on distinguishability of visualised data? is answered using a digital self -completion questionnaire and four hypotheses. 

    The data were not able to clearly determine if one of the colourmap used (YellowRed, Rainbow) was overall more effective than the other one. However, the rainbow colourmap did have marginally better results and was chosen by more participants as their preferred colourmap. The results did show that a larger number of participants disagreed that the light background made the data easier to distinguish in comparison to a dark backdrop. The results showed that more participants found it easier to see the data when seen from above than when from below. The two colourmaps were not equally effective regarding how well they could show both the VE and the data: The results indicating that the YellowRed colourmap was better at showing the details of the VE but not as good at distinguishing the data, whilst the Rainbow colourmap had the reverse results being better at distinguishing the data but less effective at showing the background. 

    The thesis concludes that it has fulfilled its goal of establishing a starting point for further studies, further studies that, according to the author, is woefully needed.

    Modernization of the legacy application simSUNDTv22021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The number of systems that are placed in the category of legacy applications steadily increases. These are systems that are either too costly or complex to maintain for usage in their current state. With this comes the need to modernize these systems. One of the systems that are in this situation is the ultrasonic testing simulation software simSUNDTv2. 

    This thesis describes the project of modernizing the simSUNDTv2 software and delivering a foundation to the customer, which can be used for further modernization work of the system. By using an iterative reengineering process, a modernized software that accommodates the customer needs is developed. From this case study, lessons learned throughout the process are compiled and presented.

    These lessons learned are meant to be considered to further improve the modernization process used, to meet the customer needs more effectively. The compiled list contains observations related to the benefits of the methodology used. It also contains modifications that should be made to the modernization process to adapt it to some ofLehman’s Laws of Software Evolution

    Funktionalitet och upplevelse för de med synnedsättning: En litteraturstudie inom UX-design2020Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    In this study, the reader will gain an insight into how to create user-friendly websites to improve the experience for people with different types of visual impairments. The purpose is to convey the methods and guidelines that exist in this area with the help of prototypes that have been developed to clearly show what potential differences arise. No tests or interviews have been conducted in the study, however the work has been based on previous research literature, for example, what definitions of visual impairments that exist. The reader also gets a good idea of what UX-design is and what significance this can have for the development on websites. The result shows how color, typography and navigation should look on a user-friendly website for the visually impaired.

    Jag ska bara ta en selfie: en kvalitativ fallstudie kring varför unga kvinnor använder sociala medier och tar selfies2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Together with the rapid technological development of the internet and smartphones, social media has quickly become a part of many people's everyday lives, especially among young women. Social media is used daily to receive news, entertainment, and keep in touch with friends, but also used as a platform to present themselves in pictures and text. Many young women choose to take pictures of themselves with their mobile that is, so-called selfies, which many then choose to add on such as Facebook, Instagram and Snapchat. The purpose of this study is to examine why young women choose to take selfies and post them on social media and how it affects the individual. A study was conducted where twelve young women aged 16-17 years were interviewed using semi-structured focus groups where discussions were held about the use of social media and taking selfies. The results showed that the interviewees felt pressure from friends and the community that they must be part of the social media to be accepted. Many of the interviewees chose to take selfies because it was an easy way to get quick confirmation from others. Pressure from friends and the community around the use of social media together with selfies create according to interviewees performance anxiety and social stress in one's everyday life that is difficult to get rid of.

    De osynliga visuella effekterna: Filmeffekterna som ska verka utan att synas2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of effects in filmmaking is not a new innovation. But today more film productions choose to use visual effects to achieve other things than spectacular explosions, space ships that invade earth or resurrected dinosaurs. Today effects are also used to create everything from natural elements like fog and snow to city scenes and buildings.

    These effects reinforce a filmed scene rather than standing out and drawing attention in them selves, hence the term "invisible effects".

    In an analysis of three different films, this essay examines the concept of "Visual Effects" and how these are used to create and reinforce the realism of the natural and urban environments. The essay and the analysis covers a variety of concepts and theories of, among other things, semiotics, perceptual realism, digital imaging and visual communication.

    The result shows that the visual impact is the sum of the different tools that form a realistic result.

    Among other things, you should customize the created visual effects for the filmed material and its attributes, such as lighting, motion and structure.

    Analysis of industrial X-ray computed tomography data with deep neural networks2021In: Proceedings Volume 11840, Developments in X-Ray Tomography XIII, SPIE , 2021, Vol. 11840Conference paper (Refereed)
    Abstract [en]

    X-ray computed tomography (XCT) is increasingly utilized industrially at material- and process development as well as in non-destructive quality control; XCT is important to many emerging manufacturing technologies, for example metal additive manufacturing. These trends lead to increased needs of safe automatic or semi-automatic data interpretation, considered an open research question for many critical high value industrial products such as within the aerospace industry. By safe, we mean that the interpretation is not allowed to unawarely or unexpectedly fail; specifically the algorithms must react sensibly to inputs dissimilar to the training data, so called out-of-distribution (OOD) inputs. In this work we explore data interpretation with deep neural networks to address: robust safe data interpretation which includes a confidence estimate with respect to OOD data, an OOD detector; generation of realistic synthetic material aw indications for the material science and nondestructive evaluation community. We have focused on industrial XCT related challenges, addressing difficulties with spatially correlated X-ray quantum noise. Results are reported on training auto-encoders (AE) and generative adversarial networks (GAN), on a publicly available XCT dataset of additively manufactured metal. We demonstrate that adding modeled X-ray noise during training reduces artefacts in the generated imperfection indications as well as improves the OOD detector performance. In addition, we show that the OOD detector can detect real and synthetic OOD data and still model the accepted in-distribution data down to the X-ray noise levels.

    Automatisering av serversäkerhetsvalidering2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis evaluates whether there exists a tool that the corporation Zetup can use seeing that they search for a concept to validate standardized and secured installs of various servers. The validation of these installs should be able to be automated, verified continuously during a systems lifetime and should also be able to be modified for specific conditions.

    The tool that was chosen for this evaluation was the security organization Center for Internet Security’s CIS-CAT Benchmark Assessment Tool which uses XML-files, so called benchmarks, consisting of a number of verifications which checks whether a target system is configured in conformity with security configurations that the Center for Internet Security has produced for maximal information security. A run of CIS-CAT results in a HTML-document which explicitly presents the result of each verification specified and grades the configuration of the target system. For this purpose, Zetup has chosen 22 requirements that their standard server should live up to. Most of these verifications were already configured, others had to be created.

    Initially, it was verified that the server was configured in accordance with the recommendations. Then, 10 misconfigurations were introduced to verify that the tool actually could find all misconfigurations.

    The evaluation showed that the tool is very useful. CIS-CAT was easily configured according to the organizations specific conditions and all introduced misconfigurations were found. CIS-CAT complies with the requirements Zetup has set although disadvantages also emerged. A great advantage is that with a tool such as this, you can start working proactively and discover misconfigurations before they affect a system negatively. Disadvantages worth mentioning are for example that the tool is not very helpful when it comes to error messages when misconfiguring the benchmark file. Another disadvantage is that a lot of resources are required when working with a tool like this; Benchmarks must be maintained and modified as new requirements emerge and old ones vanish. Also, someone must review the result of every run of CIS-CAT and fix each encountered misconfiguration

    Log4shell: Vad är det och hur har det påverkat oss?2022Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    This degree project focus on what the exploit Log4shell is, and how it has affected different organizations. Log4j is a logging-tool that is used wide within the company-world and when the exploit of the tool was discovered many people were affected.

    The purpose with this project is to figure out how organizations has been affected and how they have handled the exploit using a survey. A recreation of an attack has been done to get a deeper knowledge of how the exploit works and how hard it is to execute.

    The survey shows that the companies has handled the exploit quite similar to each other and the answers are analysed in this project. The recreation of the attack shows that it is not impossible for an unexperienced malicious person to utilize the exploit. This is shown with a step by step-list and a discussion on the subject.

    Laptopers in an educational practice: Promoting the personal learning situation2010In: Computers and education, ISSN 0360-1315, E-ISSN 1873-782X, Vol. 54, no 2, p. 311-320Article in journal (Refereed)
    Abstract [en]

    In this article an ethnographical study of laptopers' activities during lectures in a university milieu is analyzed as different kinds of involvements. Through interviews and observations we have focused on how these involvements influence the laptopers' alignment towards the educational practice. The analysis shows the importance of separating the educational practice and the personal learning situation. Studying students' learning intentions, rather than certain laptop related activities, we get a deeper understanding of the role the laptop can take during learning activities. Five general characteristics of laptoping are found. Negotiating the laptops' different roles in the educational practice opens up for an understanding of the students personal learning situation as being more than just listening to a lecturer. Additionally, competent integration of digital tools into the learning situation extends the dimensions of the lecture beyond the lecturing hours and personal note taking. Such knowledge is vital for creating foundations for digital competency in a digitized society. © 2009 Elsevier Ltd. All rights reserved.

    Abstract [en]

    This article presents preliminary findings on how the introduction of patient-generated health data (PGHD) triggers changes during patient-nurse consultations. This article builds on a two-year case study, examining the work practice at a cancer rehabilitation clinic at a Swedish Hospital using PGHD. The study focuses on how nurses’ use data, gathered by patients with a mobile phone app, during consultations. The use of PGHD introduce a change in the translation work, the work of turning rich patient descriptions and transform them into data, during the consultation for documentation and clinical decision-making. This change affects precision, questions asked and the use of visualizations as well as the patient-nurse decision making. © 2018 European Federation for Medical Informatics (EFMI) and IOS Press.

    Lastbalanseringstekniker över trådade samt trådlösa länkar2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today’s computer networks are designed to deliver high throughput and reliable delivery, a big part of designing high-performing networks is to load-balance in order to achieve high data-rates. This work compares the two different load-balancing methods Per-packet and Per-destination load-balancing and their behaviours in a wired and in a wireless environ-ment. This paper focuses on the throughput of Transmission Control Protocol (TCP) and File Transfer Protocol (FTP) in such scenarios and also measures unwanted traffic such as retransmissions and duplicate ACKs to analyse TCP’s behaviour in a wireless load-balanced environment.

    Per-packet and Per-destination load-balancing was tested in two scenarios, in scenario one both load-balancing methods was used to load-balance between two networks connected with dual wired links. In scenario two the same test was repeated between two networks connected together with dual wireless bridged links. Additionally retransmissions, duplicate Acknowledgement (ACK) packets and amount of packets out of order was also measured during scenario two. In average Per-packet load-balancing achieved higher data-rates in a wired environment while per-destination achieved higher data-rates in a wireless environment. The amount of unwanted traffic was increased while using per-packet load-balancing over wireless links
