    Vad är svenska bilisters inställning till självkörande bilars ageranden i etiskt svåra situationer?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to investigate Swedish motorists' attitudes towards self-driving cars. The thesis highlights advanced ethical decisions and ethical problems that exist for self-driving cars.

    To answer the question "What is the attitude of Swedish motorists towards self-driving cars and their actions in ethically difficulty situations?" a qualitative method has been applied. Artificial intelligence is a broad area with many domains, and therefore a delimitation has been made to the automotive industry.

    By using interviews and literature studies, the ethical dilemmas have been established for self-driving cars. The results of this literature study have been analyzed together with interviews for the study.

    Problems that have been identified with self-driving cars is that they are responsible for the event of accidents and decisive in ethical situations. Another problem identified in this study is the question of whom should be given priority in a situation where an accident is inevitable. The result has revealed that the actions of cars do not always comply with the driver's ethical principles, and that society usually lacks knowledge in the area of self-driving cars. People could act on reflexes in sudden incidents, which is different from a system that can make faster calculated decisions.

    Communication and Collaboration Gaps among PhD Students and ICT as a Way Forward: Results from a Study in Sweden2015Conference paper (Refereed)
    Abstract [en]

    The low completion rate and slow progress in PhD education have been highlighted in many studies. However, the interaction problems and communication gaps that PhD students encounter make this attempt even more challenging. The aim of this study is to investigate the peer interaction problems and ICT based solutions from PhD students’ perspectives. The data collection method was an online questionnaire and in-depth interviews were used to follow up. The target group for the survey was the PhD students in Computer Science at Stockholm University. The total number of respondents for the survey was 53 PhD students and eleven randomly selected PhD students for the interviews. The results reflected a lack of peer interaction as an important issue in the perspective of the students. Based on this, the study showed several ICT solutions that have the potential to reduce the interaction problems and thereby improve PhD students’ collaborative learning and research quality.

    Virtual Reality och Augmented Reality inom pedagogiken: Lärares uppfattningar om Virtual Reality och Augmented Reality som ett hjälpmedel iutbildning på grundskole- och gymnasienivå2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att med hjälp av en kvalitativ datainsamling undersöka lärares åsikter samt uppfattningar av att tillämpa Virtual Reality och Augmented Reality i utbildningen. För att besvara studiens frågeställningar har empiri samlats in med hjälp av semistruktureradeintervjuer tillsammans med fem lärare från olika skolor i Sverige. Studiens diskussion har haft sin utgångspunkt i tidigare forskning som undersökt tillämpningen av Virtual Reality och Augmented Reality. Utifrån det resultat av de intervjuer som bedrevs med lärarna gick det att hitta ett antal gemensamma och återkommande teman i lärarnas åsikter och uppfattningar om Virtual Reality och Augmented Reality som ett hjälpmedel inom pedagogiken. Resultat visar att lärarna generellt sett är positivt inställda gentemot en framtid där Virtual Reality och Augmented Reality är ett vanligt inslag i pedagogiken, men de menar ändå på att det finns ett antal hinder som måste övervinnas för att nå denna verklighet.

    Performance of Network Redundancy in SCTP: Introducing effect of different factors on Multi-homing2010Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The main purpose of designing the Stream Control Protocol (SCTP) was tooffer a robust transfer of traffic between the hosts over the networks. For this reasonSCTP multi-homing feature was designed, in which an SCTP sender can access destinationhost with multiple IP addresses in the same session. If the primary path between the sourceand the destination is down, the traffic may still be sent to the destination by utilizingredundant path. And SCTP multi-homing also supports for the concurrent multipathtransfer of traffic. This paper introduces the effect of different network factors likeconcurrent cross traffic, congestion control algorithms and SACK timers on multi -homingfeature of SCTP. Throughput and end-to-end packet delay were used as performancemetrics to introduce the effect of these factors. From the study it was introduced thatconcurrent cross traffic in the network behaves same on multi -homed interfaces and bothinterfaces were affected almost same. It was concluded that congestion control algorithmsalso affects on multi-homing, the RED congestion control algorithm reduced delay andimproved throughput of the SCTP multi-homing. In RFC4960 recommended SACK timeris 200ms, but when 100ms SACK timer was used with concurrent multipath transfer inSCTP (CMT-SCTP) multi-homing, the high throughput and low delay was achieved ascompared with 200ms and 300ms, which indicated that different SACK timers affects onmulti-homing feature of SCTP. All the simulation works have been conducted in NS2network simulator.

    Building complex GUIs in Plan 92009In: Proceedings 4th International Workshop on Plan9, Athens, GA: University of Georgia , 2009, p. 15-21Conference paper (Other academic)
    Abstract [en]

    How can non-trivial graphical user interfaces be designed in Plan 9 without them losing their minimalistic style? Different toolkits are discussed, and a proposal for a tabbed toolbar is suggested as a way to add functionality without cluttering the interface and avoiding the use of pop-up dialog boxes. A hypothetical port to the GUI in LyX is used as an example.

    A light-weigh non-hierarchical file system navigation extension2012In: Proceedings of the 7th International Workshop on Plan 9 / [ed] Eric Jul, Dublin, Ireland, 2012, p. 11-13Conference paper (Other academic)
    Abstract [en]

    Drawbacks in organising and finding files in hierarchies have led researchers to explorenon-hierarchical and search-based filesystems, where file identity and belonging is pred-icated by tagging files to categories. We have implemented a chdir() shell extension en-abling navigation to a directory using a search expression. Our extension is light-weightand avoids modifying the file system to guarantee backwards compatibility for applicationsrelying on normal hierarchical file namespaces.

    Helping Out Refugees: the Way Forward Stakeholders' Activities for Newcomers in Trollhättan2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study used the qualitative research approach to investigate stakeholders' activities, stakeholders' opinions on technology, stakeholders' opinions on newcomers and problems of stakeholders in Trollhättan. Interest was on provided activities of the stakeholders'. With the actor network theory (ANT) framework, the study addressed the problem of newcomers to know about stakeholders' activities in Trollhättan. Semi structured in-depth interviews were conducted on seven stakeholders in Trollhättan municipality. A private company, Trollhättan Municipality Employment Office, the Red Cross, a university and three non-profit organizations. Data were analyzed based on summative content analyses. The study revealed that stakeholders arrange varied types of initiatives but it was hard for refugees that were placed in Trollhättan, especially newly arrived in Trollhättan to get access to the initiatives. The study concluded that reaching out to newly arrived newcomers is a major problem for stakeholders in Trollhättan.

    Behovet av ett mobilt informations- och dokumentationsverktyg i hemtjänsten: Personalens perspektiv2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Although the work in home care businesses most often are mobile, the documentation and information management often occurs in information systems through desktop computers. The need for mobile solutions have become more relevant as they may contribute to increased safety, improved quality and time savings. However, research shows that business knowledge is often overlooked in the development of health systems, which contributes to IT support that are not adapted to the business needs. This study aims to increase understanding on how home care staff believes that mobile IT support the care work and organization routines.

    The study was conducted in a home care business through qualitative interviews of six respondents and a thematic analysis model has been used, containing three theoretical areas: Efficiency, Ease of use and Usability, Satisfaction and Motivation. The results show that a mobile IT support would represent a clear advantage in the business and that the existing information system could either be supplemented or replaced. However, the staff still have fears and negative attitudes towards the obstacles and risks of what new technologies can bring to the table.

    Challenges in designing virtual environments training social skills for children with autism2006In: International Journal on Disability and Human Development, ISSN 1565-012X, Vol. 5, no 2, p. 105-111Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to explore particular challenges faced when designing virtual environments for children with autism, with the purpose of training social skills. Our findings are based on studying autistic behavior during three years (primary and secondary sources), analysis of related system and other computer mediated assistive technology, as well as general game design. From these studies, we have identified eight critical design parameters that must be adjustable in a system suitable for autistic persons. The importance of the parameters, their variation range, as well as the need for independent adjustment of these were estimated and verified by experienced expert pedagogues.

    Organizing in the age of digital product platforms: The work of integrated vehicle control engineers2019In: CEUR Workshop Proceedings, ISSN 1613-0073, E-ISSN 1613-0073, Vol. 2398, p. 17-25Article in journal (Refereed)
    Abstract [en]

    As flexibility and generativity of digitized information continuously afford new possibilities, a significant challenge for organizations becomes pinpointing practices that are befitting from various aspects. Two overarching digitization eras have so far determined the greatness of the challenge for organizations; 'computerization', and 'the Internet'. Today, a third era of digitization is marked by the emergence of digitized products. As increasing numbers of code line and software are being incorporated in previously physical products such as cars, they can be used as complete products on one layer, and simultaneously turn into platforms enabling other firms to develop and integrate new components, content, or services on another layer. As digital product platform's multiple design layers need to be open to various applications and agendas, their development requires new justifications and approaches for organizing work. By applying a Neo Socio-Technical Systems frame of reference on the work of engineers as they engage in developing digitized products, we 1. discuss changes of work and organizing along three eras of digitization, 2. provide a rich empirical instance by identifying what steps engineers take in preparation for developing digital product platforms, and 3. discuss the implications of these steps for the literature on practice and organizing. ©Copyright held by the author(s).

    Abstract [en]

    This report examines a number of free WiFi-hotspots that are offered by various companies in central Gothenburg and how they compare to the mobile networks. Traffic, capacity, channel frequencies, signal strength and acceptable use policies were all analyzed and verified.

    The readings showed that the networks were generally not utilized to their full capacity, a probable cause might be the distribution of mobile networks and that channel distribution was with a few exceptions allocated correctly according to 802.11 standards. Acceptable use policies on the networks were implemented by the larger chains but not by the smaller companies

    Dags att köra agilt!: vilka är de främsta för-­ och nackdelarna med att använda en agil systemutvecklingsmetod?2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det övergripande syftet med studien och rapporten var att bidra till en ökad förståelse kring agila metoder för att kunna fatta beslut om användande av en agil systemutvecklingsmetod är motiverad. Studien var av kvalitativ karaktär och arbetade utifrån frågeställningen "vilkade främsta för- och nackdelarna med att använda en agil systemutvecklingsmetod?". Med hjälp utav djupintervjuer och litteraturstudier samlades empiri och vetenskaplig teori in.Vilken utvecklingsmetod en organisation använder har visats sig vara avgörande för organisationens produktivitet och kvalitet på dess resultat. Den sekventiella metoden har varit normen för IT-utvecklingsprojekt under en lång tid, vilket är orsaken till att vissaorganisationer fortfarande använder den. Allmänna problemen med den sekventiella metoden är att den har svårt att hantera förändringar, svårt att leverera vad kunden efterfrågar samt att modellen skjuter fram riskfulla och utmanande moment till slutet av projektet. Att istället byta till en agil metod kan vara lösningen på dessa problem då metoden är framtagen för att vara flexibel med nära kundsamarbete för att säkerställa att resultatet som levereras stämmer överens med vad kunden efterfrågade. Slutsatsen av studien har visat sig vara att de främsta fördelarna med en agil metod är: Den levererar vad kunden efterfrågar, kan enkelt hantera kravförändringar, är anpassningsbar samt ger enhögre kvalité på slutprodukten. De främsta nackdelarna studien har visat sig vara: Hantering utav dokumentation, svårt att skala upp till stora organisationer samt att metoden är krävande.

    Vegan lifestile on Facebook: An online ethnography study2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years there has been an increase in the number of vegans in the world. The main goal of my research is to understand the vegan struggles in their daily life and study how Facebook might help them solve these difficulties. This master's thesis focuses on the user perspective and how they perceive barriers to follow a vegetarian lifestyle in Spain. The research questions are about finding those barriers and knowing how they could be solved by using Facebook groups. For this purpose, an ethnographic approach has been used.

    The target group of this study are vegans who have gone through the time of change and may have had some problems in making that decision. Fifteen vegans have been interviewed to find challenges that have arisen when they have changed their lifestyles. After that, an online ethnography study has been performed by observing the content of a Facebook group, called "Vegetarianos y Veganos – España", focusing on publications where group members were asking for advice, information or solutions.

    The results indicate that the investigated group of Facebook is essential for the exchange of information, knowledge and experience. The members also contribute to increased knowledge through publications and comments. But most importantly, the members receive solutions to the problems they share with the group.

    Simulated Provocations: A Hypermedia Radio Theatre for Reflection on Classroom Management2018In: Journal Simulation & Gaming, ISSN 1046-8781, E-ISSN 1552-826X, Vol. 49, no 2, p. 98-114Article in journal (Refereed)
    Abstract [en]

    Background. Learning to manage a classroom is a difficult but important part of teacher education. Earlier research on simulations for learning classroom management has highlighted the difficulty of supporting reflection.Purpose. This case study explores and evaluates the design of a simulation for student teachers' reflection on classroom management.Design. The design process resulted in the scenario-based SIMPROV simulation, which was made in the form of a hypermedia radio theatre that students go through in pairs or triads. Authoritarian, authoritative, democratic, and compliant leadership styles were built into the choices student teachers made.Evaluation. The simulation was evaluated in two courses where the participants' level of reflection and perceived knowledge improvement was measured using a questionnaire. Forty-three first-year student teachers, 48 third-year student teachers, and 38 of the student teachers' mentors participated in the evaluation.Results. The results indicate that participants engaged in reflection and understanding to a high degree, and only to a low degree in critical reflection or habitual action.Conclusions. The conclusions are that the scenario-based simulation designed as a hypermedia radio theatre supported knowledge improvement, understanding, and reflection and that social interaction during and after simulation sessions was an important feature.

    Ad Hoc Networks: Performance Evaluation Of Proactive, Reactive And Hybrid Routing Protocols In NS2 2010Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    No infrastructure, no centralized administration and self-configuration are the main characteristics of MANETs. The primary motivation of MANET deployment is to increase portability, mobility and flexibility. However, this mobility causes an unpredictable change in topology and makes routing more difficult. Many routing algorithms have been proposed and tested over the last few years in order to provide an efficient routing in Ad Hoc networks. In this report we will show our conducted study with AODV (reactive), DSDV (proactive) and ZRP (hybrid) routing protocols. The performance of routing protocols have been evaluated carefully by analyzing the affects of changing network parameters such as, number of nodes, velocity, pause time, workload and flows on three performance metrics: packet delivery ratio, routing cost and average end- to- end delay. All the simulation work has been conducted in NS2. Our simulation results show that AODV gives better performance in all designed simulation models in terms of packets delivery ratio. DSDV shows the second best performance. Performance of ZRP is found average.

    Mätning av uppstartstid i multicastprotokollen PIM dense-mode och PIM sparse-mode2014Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    This report studies which multicast protocol that requires the least amount of time to forward a multicast stream from sender to receiver. The protocols measured are IPv4 PIM dense-mode, IPv4 PIM sparse-mode and IPv6 sparse-mode. The measurements are based on the time between the client announcing participation in a multicast group to actually receiving the first multicast stream packet from the router. In a lab environment with Cisco 2901 routers we came to the conclusion that IPv4 PIM dense-mode required the least amount of time compared to IPv4/IPV6 PIM sparse-mode. Every protocol managed to stay below 20 milliseconds median, which is within the limit of what a human sees as instantaneous

    A Concept of an Interactive Controlled Vertical Blind2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    One of the most common devices found worldwide in todays society, is the curtain in

    various designs. Different designs which requires different types of physical efforts to be

    used and adjusted to achieve the intended purpose.

    Due to lack of features in a regular vertical blind and its construction, it makes it hard to

    use and apply with normal behaviours of the human. Where the basic idea is based on a

    static design with a parallel relationship between the individual vertical blinds is the

    prototype based on individual movements of the blinds. A static relationship, which

    requires repeated adjustment through the day and the movement of the sun to achieve the

    desirable functionality. However, when the user gets interrupted and distracted for example

    at work repeatedly during a complete day, his or her performance and creativity at work

    will be reduced.

    In this paper I have chosen to focus on the interaction design of the vertical blind and how

    to improve the interaction relationship between it and the user. Also showing how it is

    possible to create solutions for a simple and common unit like a vertical blind, by means of

    interactive models, use cases, technical predictions and a proposal of a future GUI that

    makes it possible to implement the models in a prototype of an embedded system.

    Evaluating Information Systems by using interpretive evaluation approaches and models2009Book (Other academic)
    Abstract [en]

    As information systems/technologies (IS/IT) become embedded in organizations, these systems cannot be isolated from important issues such as human intellect, culture, philosophy, politics and socio-organizational changes. Limited business resources on one hand and the various concerns and demands from different stakeholders on the other hand have led to an ever-growing need to evaluate IS/IT investments. In other words, due to the heavy rise of IS/IT costs IS/IT investments must be justified. Evaluation of IS/IT investments is generally taken to mean the identification and the measurement of capital expenditures spent on and the initial anticipated revenues gained from the deployments of these systems (IS/IT). One of the main fundamental characteristics of interpretive approach (IA) is to highlight and facilitate evaluation as an interactive learning process. Interpretive approach concentrates on the lifecycle perspective of IS/IT investments argued to be a complex managerial issue. It is crucial to notice that stakeholders, their claims, concerns and issues are at the core of IEA.

    A Systematic Process for Selecting a Typical Case in School Setting2013In: Proceedings IRIS 36: August 11-14 2013 at Gran, Norway / [ed] Bratteteig, Tone, Aanestad, Margunn & Skorve, Espen, Oslo: University of Oslo , 2013, p. 461-472Conference paper (Refereed)
    Abstract [en]

    This paper describes the rationale behind the concrete steps how we systematically have gone through the case selection process as the first phase of a research project named Consequences of the Digitalization of Schools. The project is a single-case longitudinal (5-year long) study and adopts a so called Whole-School Approach. Previous research has criticized case studies for lack of both systematic approach and transparency in the presentation of the case selection process. The purpose of the presentation of this case selection process is to contribute to enhancing understanding of and broadening knowledge on systematic and transparent case selection techniques. The SIRIS database has been used to select a typical Swedish primary school in the chosen municipality where the project will be conducted. The SIRIS database contains annually statistics from all primary schools in Sweden, and is available online for public use. We demonstrate how and why a particular school representing a so called typical school was selected as our case.

    Managing the Digitalization of Schools: an explorative study of school principals’ and IT-managers’ perceptions2014Conference paper (Other academic)
    Abstract [en]

    The deployment of ICT in school setting is in many ways a complex managerial task that involves several stakeholder groups. Firstly, principals and deans have to relate to the local, regional, national, and international policies and governing systems. Furthermore, the voices of teachers, students and their parents have to be considered and negotiated. In this paper, we explore how school principals’ and municipal IT-managers’ perceive the usefulness and the potential role that ICT play in the school context. In a pilot study of a single school district in a Swedish municipality, we have interviewed representatives from the municipal board of education, the municipal IT-support for schools, and two principals. By using the Technology Acceptance Model (TAM3) as an analytical lens to understand the two constructs of “Perceived usefulness” and the possible role of ICT, we conclude that the barriers for successful integration of IT into educational practices requires firstly overcoming the lack of coordinated ICT investment strategy and tracking of ICT. This can be done by having a clearly articulated ICT policy distributed to school staff which we argue will positively influence the perceived usefulness as expressed by principals and their governing body. Secondly, inclusion of ICT in all aspects of teachers’ professional school activities will bring change to school activities and processes.

    Användarvänlig interaktion med mobila enheter: En studie av centrala designprinciper för mobila enheter2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The background of this study presents the way that technology for mobile units has developed in a quick pace, which has led to an expansion of smartphone usage. While the smartphone usage has expanded, the websites hasn't followed the same development. The problematic discussion in this area deals with the difficulties of adapting interfaces from a stationary computer to the interface of a smartphone.

    Selected mobile sites from different airlines have been investigated, based on how user-friendly they are. The study aims to investigate the problems that can arise when airline sites are not user-friendly, and illustrate how the various design principles are applied in these selected websites. Previous research regarding this topic shows that it's difficult to adapt a website to a smartphone. The same design principles are required as for the ordinary websites, but they need to be performed in a stricter manner. Moreover, earlier research shows that usability is an important aspect in the design of the site for smartphones.

    A qualitative approach was applied in the study, where the approach to collect materials for the study has applied the method think aloud, and interviews have been conducted in order to gain a deeper understanding. The result of this study shows that the investigated mobile websites suffer of severly insufficient usability in regards to the investigated design principles and the principles of usability. It is crucial to apply design principles for good mobile usability to the areas that are important for the interaction between the website and the user. The website and its functions should adapt, depending on the device the user uses to browse the website. The website should not confuse the user and should always give feedback on the whereabouts of the user on the website.

    Vi ses på nätet: en studie om ungdomars sätt att umgås via datorn2015Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    When young people today tend to spend part of their leisure time in front of the computer and communicate via various internet-based communication tools may the question be asked if the communication is different from the communication that takes place in reality, and this in turn influences the ability to communicate in an empathic way with their fellow human beings. The question formulation is about if communication via the internet and in real life is different from each other, how young people look at the interaction via the internet-based communication tools, and how this affects them. The method that has been used is qualitative interviews to get as detailed answer as possible by the respondents.The survey results show that young people differ in their way to be, depending on the form of socializing utilized. The selection of social company form are based on mood, the home's rules, weather and season. Internet-based communication tools are used more as a supplement to physical meetings rather than replacing them, in spite of this there is a skepticism from the parents against Internet communication. It can be concluded that the interaction and communication via the internet is not a substitute for physical interaction with other people, but rather serves as a complement to this. An awareness that the communication over the internet can seem harsher exists and it is not used in physical meetings and that communications over the internet seems to be more intense during a short period of adolescence can also conclude that the interaction with other people in real life is not significantly affected.The work does largely agree with what previous research has shown.

    The Great Learning Experience: An attempt to understand learning from the wies of the millenial learners.2011In: Connecting Communities: The A B C D of eLearning, Palawan, 2011, p. 1-5Conference paper (Other academic)
    Abstract [en]

    Millenial learners are individuals born after 1985 with very wide exposure to various types of media enhanced by technology. They are persons who had listened to music while in the wombof their mothers and had watched television starting at age 0. Most of them would have hada music player or a game pad or a mobile phone at age 8. (Deterle, Dede and Schrier, 2008)These millenial learners grew up with constant web connectivity at their fingertips to assist themin their homeworks.

    The present pedagogies our academic institutions employ to support the learning style ofthe web generation of students may not be as suitable. Social constructivism, transformativelearning or problem-based learning, while prevalent in the Asian context, may be more perfectfor cognitively dynamic students. Our students nowadays are more adept to constructingknowledge, content (Attwell, 2007) and even more independent in their learning priorities.This study attempts to understand the new learning practices among our students. This studyattempts to find out how college students define what a good learning experience is. It is alsothe intention of the study to explore new educational practices and hopefully drive ways ofdesigning and developing the future of learning activities.

    The study was conceived in May 2011 and was planned to collect data in the form of shortvideos in a span of six months, from June to December. There will be two sets of samples, onefrom the students of De La Salle University of the Philippines (DLSU) and the other from thestudents of University West (UW) in Sweden.

    The experiment asked for a two minute video that will be created and expressed by anindividual or group of students. This meant planning and organization to compose the thoughts,the message and the content of the video. Since this contains the expression of the studentsthemselves, the self-expression equates to a great degree of authenticity.

    This paper will impart the work-in-progress of this experiment, the Great Learning Experience.To date, there are twenty videos from DLSU and fifteen videos from UW. This paper will tell themethods used in the different classes and the initial findings. Comparison of the UW and DLSUvideos is not included in the paper.

    A Comprative Study of Forward and Reverse Engineering in UML Tools2007In: Proceedings of the International Conference on Applied Computing: Salamanca 2007, Spain, IADIS , 2007, p. 535-540Conference paper (Refereed)
    Abstract [en]

    In the process of developing computer based applications the use of descriptive models to depict the architecture and design of the application is practical and brings many advantages. The most commonly used standard today is the Unified Modeling Language. There are many tools that implemented support for this standard for modeling, and they vary in functionality. A comparative study, including a selection of these tools, will show advantages and disadvantages for each tool. The purpose of this study is to test a selection of these modeling tools for a typical three-tier layered web service application. The tools tested in this study are Microsoft Visual Studio 2005 .NET Beta, PowerDesigner and Visual Paradigm. Rational Rose would have been included if it would have supported C#. In this study tests are performed in regard to modeling a class diagram, forward engineering to source code from the class diagram and reverse engineering from source code to class diagram. Despite the shortage of diagram types MS Visual Studio proved to be the most reliable tool for this particular type of applications.

    Digital Nudging för hållbarhet: En experimentell studie om digital nudging för hållbarhet2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study examines how digital user interface systems with digital nudges shaped based on FBM (Fogg Behavior Model) and the PSD model (Persuasive Systems Design) can be used for the promotion of sustainable consumption patterns.

    The study's data collection methods are experimental user tests in a semi-controlled environment where user data on a mobile-based user interface design is collected for analysis. The user interface tested was of a prototype mobile app, made for the purpose of this study. Complementary interviews of the participants were performed in connection with the tests in order to gain a deeper understanding of the design situation and the factors that may have an impact on the users' choice, their experiences and attitudes, among other things.

    The results of the experiment in which various digital nudges are tested are interpreted and analyzed from a persuasive design perspective using the FBM and PSD models that conceptualize persuasive design. The intention is to see which factors lead users to more sustainable consumption behaviors.

    We conclude with a discussion on how to apply these models in order to design nudges in context for sustainability purposes. The discussion is intended to lead to an inductive conclusion about which variables and which conditions work best to lead users to more environmentally friendly alternatives using nudges.

    Distansmöten i verksamheten: En fallstudie av distansmöten i Fyrbodals kommunalförbund2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the essay is to investigate what experiences and views officials and management, within a public organization such as Fyrbodals Kommunalförbund, have regarding distance meetings. Another purpose of the study is to account for what factors the respondents consider important in order to improve the quality and efficiency of distance meetings. In this essay meeting culture, meeting tools and meeting management within Fyrbodals kommunalförbund are focused. I choose to do the research in this particular organization due to earlier experiences in it, which have motivated me to study it further.

    Case study, with the emphasis of qualitative studies, has been used as research method. I have had a qualitative approach in my essay, with aspects such as usability regarding technique and individuals' experiences and views of distance meetings as a main focus. The different methods used in this case study were semi structured interviews, studies of documents and literary studies. By partly using a few selected parameters of Unified Theory of Acceptance and Use of Technology, (UTAUT), usability regarding technique could be analyzed in an efficient manner. UTAUT is a theory based on eight other models for user acceptance of new technique. In my interviews, I was able to identify several issues, within the frame of usability. By using UTAUT, patterns and formations could be discerned. The results of the study show that distance meetings overall is something positive, due to the fact that they do not include travelling, can save money and because the distance meetings are efficient. The most important findings that affect efficiency as well as quality when using distance meetings were a clear, predetermined structure of the meeting using a trained chairman to lead them, and repetitive training of the communication tools.

    Towards Automation of Non-Destructive Testing of Welds2011Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    All welding processes can give rise to defects that will weaken the joint and can lead to failure of the welded structure. Because of this, non-destructive testing (NDT) of welds have become increasingly important to ensure the structural integrity when the material becomes thinner and stronger and welds become smaller; all to reduce weight in order to save material and reduce emissions due to lighter constructions.

    Several NDT methods exists for testing welds and they all have their advantages and disadvantages when it comes to the types and sizes of defects that are detectable, but also in the ability to automate the method. Several methods were compared using common weld defects to determine which method or methods were best suited for automated NDT of welds. The methods compared were radiography, phased array ultrasound, eddy current, thermography and shearography. Phased array ultrasound was deemed most suitable for detecting the weld defects used in the comparison and for automation and was therefore chosen to be used in the continuation of this work. Thermography was shown to be useful for detecting surface defects; something not easily detected using ultrasound. A combination of these techniques will be able to find most weld defects of interest.

    Automation of NDT can be split into two separate areas; mechanisation of the testing and automation of the analysis, both presenting their own difficulties. The problem of mechanising the testing has been solved for simple geometries but for more general welds it will require a more advance system using an industrial robot or similar. Automation of the analysis of phased array ultrasound data consists of detection, sizing, positioning and classification of defects. There are several problems to solve before a completely automatic analysis can be made, including positioning of the data, improving signal quality, segmenting the images and classifying the defects. As a step on the way towards positioning of the data, and thereby easing the analysis, the phase of the signal was studied. It was shown that the phase can be used for finding corners in the image and will also improve the ability to position the corner as compared to using the amplitude of the signal. Further work will have to be done to improve the signal in order to reliably analyse the data automatically.

    En mobil stads-applikation i Trollhättans utveckling mot en smartare stad2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper maps out the possibility to create and implement a mobile application based on a project brief from mCity, that will help Trollhättan in becoming a smarter city. The reader gains a deeper understanding of how, with the help of data collection and analysis can infer patterns and based on that, create an interface as well as content that meets project objectives and contribute to the development from a Smart City perspective.We have, by interviewing local government employees and citizens, created a prototype built upon approved methods in usability that meets the above criteria which has also been tested on further citizens to evaluate the usability and user experience.Using this mapping, we believe that the future development and implementation of this and/or a similar type of application has been facilitated and the reconciliations made, indicate that such an implementation would also be of Trollhättan's advantage in its quest to become a smarter city

    A First Draft of RATF: A Method Combining Robustness Analysis and Technology Forecasting2006In: Information Technology: New Generations, 2006. ITNG 2006. Third International Conference on, 2006, p. 72-77Conference paper (Other academic)
    Abstract [en]

    This paper is based on an extensive study performed on a large software suite for over a decade. From the experiences derived from this study we created a first draft of a method combining an extended robustness analysis (RA) method with the future oriented method of technology forecasting (TF). In this method TF provides information about the systems future evolution to the RA which then generates the software design. The RA and TF methods then form a feedback loop, which results in an improved reusable and robust software design. The purpose of the RATF method is to predict the evolutional path of the software system, thus making preparations for (example) functionality that will be needed in future generations, i.e. utilizing the power-of-prediction to implement the base of tomorrow's functions today

    Combining robust analysis and technology forecasting: A missing combination in contemporary methods2006In: Proceedings of the IASTED International Conference on Software Engineering: as part of the 24th IASTED International Multi-Conference on APPLIED INFORMATICS, Innsbruck, 2006, p. 329-334Conference paper (Other academic)
    Abstract [en]

    Seven software engineering methods and one general purpose system engineering method TRIZ was evaluated concerning their abilities to combine software technology forecasting, that is prediction of potential software evolution with robustness analysis, which is a method to model a system tolerant to changes. None of the investigated software engineering method or process concepts combines software technology forecasting with robustness analysis to any great extent. Several of the methods evaluated do contribute with techniques and principles, that potentially could be combined and give systematically technology forecasting with comprehensively robustness analysis though. This defines a new frontier for research into a combined "super class" method for software development.

    Online and offline social ties of social network website users: An exploratory study in eleven societies2009In: Journal of Computer Information Systems, ISSN 0887-4417, Vol. 50, no 1, p. 54-64Article in journal (Refereed)
    Abstract [en]

    This study presents results of a survey about social network website (SNW) usage that was administered to university students in China, Egypt, France, Israel, India, Korea, Macao, Sweden, Thailand, Turkey, and the United States. The offline and online social ties of SNW users were examined by nationality, levels of individualism-collectivism (I-C), gender, SNW usage, age, and access location. Contrary to existing literature, we found no differences in the number of offline friends between individualist and collectivist nations. Similarly, there was not a difference in the number of online social ties between individualist and collectivist nations. However, members of collectivist nations had significantly more online social ties never met in person. Heavy SNW users in individualist nations maintained significantly higher numbers of offline social ties; however, heavy SNW users in collectivist nations did not have higher numbers of offline social ties. Related implications and recommendations are provided.

    Visionen av det framtida stadslivet: En semiotisk analys av informationsfilmer om det Västsvenska paketet2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The future is often created by visions since we tend to strive towards them to reach the future wedesire, a vision can thus affect both lives and destinies (Rubin, 2013:40). Therefore it's relevant to attempt to understand how visions of the future are visualized and communicated. It's also important for these visualizations to be well-made and thought-through so that people understand and want to follow the vision (Baum, Locke, Kirkpatrick, 1998:45). We chose to examine this phenomenon by studying three movies about the West Swedish Package; The dream of the good life (2011), West Swedish Package - an investment that paves the way for the future (2014) och Västsvenska Paketet - Möten mellan människor (2014). Using a semiotic analysis we examined how the vision of future urban life was presented. We also looked at the rhetorical elements that are used to present the vision. We found several similarities in how the vision was presented in the films. Overall they show a very optimistic future. They paint a picture of the good life where only certain kinds of people and lifestyles are depicted. On the rhetorical plane they use a lot of emotionally persuasive arguments (patos), they try to gain trust (etos) and they use some logical arguments (logos). We also discuss if an overly optimistic image of the future could generate a negative response, especially in such ad ebated topic as the West Swedish Package.

    Abstract [en]

    Games are a natural part of many people's everyday lives and have gone from being a divergent interest to become Sweden's biggest cultural export. As a result from this expansion, digital tools had to be further developed and through this progress these tools have reached new areas of usage, which has created new challenges for game developers. The games that offers a higher purpose than pure entertainment goes under the genre serious games. Serious games are used in various application areas such as; in the military, health care, education, business, and psychology, which is the framework of this thesis. By combining and unifying previous research grounded in psychology and game science I want to answer the questions: How can games be used as a therapeutic tool in a child's grieving process? and, Which features should such a game focus on? These questions are answered through the information gathered from two interviews conducted with respondents that have different expertise within the area of this study, this to reach a broader perspective.

    A child's grieving process can manifest itself in various ways depending on the individual's level of sensitivity. It is therefore difficult to draw any general conclusions on how such a game should be designed. All games have the opportunity to motivate and engage, but this is not unique to a serious game and therefore a measurement function is essential in a digital rehabilitation tool to provide the therapist with valuable information about the patient.

    The figurative language makes it possible for the child to communicate where the spoken language sometimes has limits. For older children social support can be important as it creates opportunities to meet others in similar situations and together work towards improvement.

    Grief is a non-linear process and can present itself in many different ways and it is therefore important that the game should offer various turn-outs to make it adaptable for the individual.

    On knowledge management: a field study2000In: Internet-Based Organisational Memory and Knowledge Management, IPG Group Publishing , 2000, p. 170-198Chapter in book (Refereed)
    Abstract [en]

    It is widely acknowledged that knowledge is one of the most important assets of today's organizations. According to Davenport and Prusak (1998), knowledge is often a company's greatest competitive advantage in a global economy. How to support the company's knowledge-intensive work processes (e.g., quality support, product design or strategic planning) is therefore becoming a vital issue in many organizations worldwide. Identification, analysis and characterization of the knowledge-intensive work processes become essential in order to qualify a discussion of how to support knowledge management processes. This chapter presents, discusses and reflects upon findings from a study of how highly skilled actors manage information and knowledge, i.e., how information is gathered from a wide range of sources, structured according to needs and relevance for the users, and disseminated to the relevant suppliers in the organization. The aim of the chapter is two-folded: first, to contribute to the general empirical body of knowledge about knowledge-intensive work, especially focusing on the central characteristics of the knowledge management processes; secondly, to initiate a discussion of which overall requirements we must set up for how knowledge management processes could be supported by means of information and communication technology. Knowledge-intensive work processes often concern collaborative problem-solving and mutual support that require effective ways of handling information and knowledge between different people, both in short-term and long-term situations. The distributed and dynamic nature of knowledge management work also imposes a high degree of complexity involving many different actors with different conceptualizations, interpretations, perspectives, needs, etc. of the knowledge produced and approached. The various actors have different perspectives on the concept of knowledge. The work needed to articulate knowledge and make information and knowledge accessible becomes extremely demanding and complex. Often face-to-face interaction is required. However, in complex and collaborative work settings the problem of articulating knowledge by rich interaction and communication is obvious. The actors are distributed both geographically and temporally. There is a need for computer-based mechanisms for interaction and coordination of information and knowledge (cf. e.g., Carstensen and Wulf, 1998).
