    Gender and IT Goes Second Millennium2006In: E-CAP 2006 European Computing and Philosophy Conference, 2006Conference paper (Refereed)
    Abstract [en]

    Where does feminist research on gender and IT stand today? What are the possibilities now and for the future? How does today’s research both build on and break with earlier approaches? In this article, we make a journey, where the starting point is taken in re-visiting two positions, liberal feminism and radical feminism, in the history of gender and (information) technology. We make a historical exposé to highlight some of the questions feminist technology research has been engaged in, in order to relate, inspire, challenge and partly also provoke future research. We then link these approaches to our own position in feminist technoscience research. This perspective opens up the world of information technology as a world of networks, relations, and negotiations going on within localised and situated practices, where IT and gender are continuously co-constructing each other. Feminist technoscience research challenges much of the present understandings, interpretations and even experiences of information technology and it demands re-thinking the foundations of computing. We discuss concepts and figurations developed within feminist technoscience research, that encourage us to imagine, think and do things differently, and we ask: “How do we make a difference?”

    Detecting cheaters who utilise third-party software to gain an advantage in multiplayer video games2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Playing video games are meant to be a fun experience but something that has been proven to ruin the experience are cheaters, maybe even more so in events such as tournaments where money is involved. Even if anti-cheating software exists there also exists a research gap in the subject of cheat detection. And regarding cheat detection the question that matters the most is: how do you even detect a player that is using 3rd-party software to gain an unfair advantage in online video games? To find a solution for this problem a systematic literature review was made were data was extracted from articles relevant for the subject and summarised into results. From the results, a few elementary concepts regarding cheat detection are introduced and analysed with comparisons to the problem statement. Finally, five different types of cheat detection are shown that work by analysing objects such as behaviour, game state or memory.

    Kilowh.at – Increasing Energy Awareness Using an Interactive Energy Comparison Tool2017In: Persuasive Technology: Development and Implementation of Personalized Technologies to Change Attitudes and Behaviors / [ed] de Vries, P.W., Oinas-Kukkonen, H., Siemons, L., Beerlage-de Jong, N., van Gemert-Pijnen, L, Springer, 2017, p. 175-185Conference paper (Refereed)
    Abstract [en]

    Reducing the use of energy is important for several reasons, such as saving money and reducing impact on the climate. However, the awareness among non-experts of how much energy is required by different activities is generally low, which can lead to wrong prioritizations. In this study, we have developed an interactive tool to increase “energy awareness”. A group of 58 students first did a test to benchmark their current energy awareness, then tried the tool for 10 min, and then did the same test immediately after trying the prototype and one week after trying the prototype. In addition, they answered questions regarding which, if any, of the energy requirement of different activities surprised them, any thoughts about their own energy use aroused after using the prototype and what they thought about using the tool compared to more conventional methods of learning. The results showed a significant learning effect in energy awareness with a very strong effect size of 1.689, that they were most surprised by the energy required to produce a hamburger, 39 of 58 explicitly said they intended to change one or more aspects in order to improve their energy use, where 24 actions involved changing habits and 18 actions was of a one-time investment character. The attitude towards using such a tool instead of more conventional learning was very good and the words most frequently used to describe the tool was good, simple and easy to use, fun, and interesting, but five users also said they were bored after a while. In total the results indicate that using an interactive tool like this even for a limited time is a good way to in an efficient and fun way increase energy awareness.

    What Can You Do with 100 kWh?: A Longitudinal Study of Using an Interactive Energy Comparison Tool to Increase Energy Awareness2018In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 10, no 7, article id 2269Article in journal (Refereed)
    Abstract [en]

    Reducing the use of energy is important for several reasons, such as saving money and reducing impact on the climate. However, the awareness among non-experts of how much energy is required by different activities and appliances is generally low, which can lead to wrong prioritizations. In this study, we have developed an interactive tool to increase “energy awareness”, and performed a longitudinal study to evaluate its effect. A group of 58 students first did a test to benchmark their current energy awareness, where their current knowledge of energy used for 14 different activities, such as driving vehicles and using home appliances, was measured. They then tried the interactive learning tool for 10 min. Next, they did the same test immediately after trying the tool, then again one week after trying the tool, and finally again six months after trying the tool. The results showed a significant learning effect in energy awareness with a “huge” effect size of 2.25 immediately after the intervention, a “very large” effect size of 1.70 after one week, and a “large” effect size of 0.93 after six months. The results further showed that the respondents consistently underestimated what 100 kWh could be used for, and especially so for appliances and activities requiring little energy. Before the intervention, on average they underestimated how much 100 kWh could be used for by 95.2%, and six months after the intervention the underestimation was 86.8%.

    Att driftsätta i molnet: En undersökning i kostnader och skalningsmöjligheter2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    När en ny webbapplikation skall lanseras och driftsättas är det svårt att i förhand veta vilken datatrafik och belastning som tjänsten behöver vara dimensionerad för.

    Rapporten följer en webbapplikation som inte är förberedd för uppskalning till att bli separerad i olika komponenter för ökad skalbarhet och driftsäkerhet.

    I rapporten genomförs även en komparativ studie på olika typer av molntjänster som erbjuder infrastruktur (IaaS)-, plattform (PaaS)- och mjukvara (SaaS) som en tjänst.

    Målet med undersökningen var att hitta en kostnadseffektiv metod för att expandera applikationens infrastruktur och flytta implementationen till molnet.

    Resultatet och slutsatsen visar att den dyraste lösningen inte alltid är den bästa och i slutändan kan företag betalar pengar för resurser som de inte utnyttjar.

    Hur organisationers interna informella kommunikation förändras vid snabb tillväx: En fallstudie på operativa chefers uppfattning av det dagliga informationsflödet2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In order to reach accurate information to the right person on time, an organization's communication needs to work. Communication is therefore fundamental in order to create efficiency and is a contributing factor to their development curve. An organization's communication is usually divided into two different types; formal and informal communication.  

    This study aims to investigate how internal informal communication works for operational units in an organization that is part of a larger network, as well as investigating the difficulties that arise in connection with changes. This in turn can create a greater understanding of growing organizations' communication problems.  

    An abductive method has been used to achieve the purpose of the study and a case study has been conducted to obtain deeper information. Qualitative semi- structured interviews have been conducted to understand the respondents' story and get more nuanced information.  

    The results of the study clarify that the theory and practice are consistent in cases where informal communication causes difficulties as well as what could make it more efficient. The result shows that information overflow and ignorance about the choice of communication channel adversely affect communication. Also, difficulty adjusting the message to the recipient. Furthermore, the perception of the advantages of informal communication is united in literature, however, the respondents point out that perception differs in practice.  

    The conclusion describes the importance of paying attention to growing organizations' internal communications and information flows. The study shows that a communication strategy can contribute to more efficient communication flow for growing organizations. The conclusion also includes recommendations for organizations in growing networks, developed by comparing previous research and theories with the result.

    Värdeskapande faktorer med en informationshanteringsplattform genom Internet of Things: En fallstudie med fokus på förebyggande underhåll i en producerande verksamhet2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Internet of Things enables the creation of “smart environments”, where it is possible to exchange information between objects. This can lead to increased efficiency and automatization in different ways, for example in our homes and for business operations. An area where the interest for this technology is immense is in the industrial sector, and is referred to as Industry 4.0. For this area, the adoption of this technology is expected to, for example, improve efficiency and to predict maintenance, an approach known as e-maintenance. This new technology implies modification and development of business models and enables different types of information systems based on these. To be able to generate value for businesses when using an information management platform, variables that create value should be investigated.

     

    The purpose of this study is to examine value-adding variables, with aspects from Delone & McLean’s Information System Success Model (2003), for a specific business case by using an information management platform through Internet of Things and sensors in their operations. This study has been carried out as a case study with one of Sigma Technology’s clients, which this study was made in collaboration with. This study was carried out with an abductive research approach and a qualitative method. To examine the opinions of the company’s employees, individual, semi-structured interview was conducted. The interviews was analyzed and compared with Delone & McLean's Information Systems Success Model, to identify resemblance or divergence.

     

    The findings in this study show that the significant variables for value to be created are simplicity, information structure, accessibility and reliability. These factors are considered to be especially important, according to the respondents. Findings also show that the study is mostly consistent with the theoretical model, however, some variance has been discovered and some modifications of the model are presented. A dimension that the respondents did not consider equally important for value creation, and thus deviated from the theoretical framework, is service quality. Based on the significant factors presented in the study, the proposal is to further develop the model by adding an additional dimension, interaction quality, for the reason that the analysis of the value creating factors in this study describes this need.

    Learning machines in Internet-delivered psychological treatment2019In: Progress in Artificial Intelligence, ISSN 2192-6352, Vol. 8, no 4, p. 475-485Article in journal (Refereed)
    Abstract [en]

    A learning machine, in the form of a gating network that governs a finite number of different machine learning methods, is described at the conceptual level with examples of concrete prediction subtasks. A historical data set with data from over 5000 patients in Internet-based psychological treatment will be used to equip healthcare staff with decision support for questions pertaining to ongoing and future cases in clinical care for depression, social anxiety, and panic disorder. The organizational knowledge graph is used to inform the weight adjustment of the gating network and for routing subtasks to the different methods employed locally for prediction. The result is an operational model for assisting therapists in their clinical work, about to be subjected to validation in a clinical trial.

    Work/Life Balance and Smartphones: Can a Smartphone make a difference?2010Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    This thesis examines the relationship between work/life balance and Smartphones (Blackberry, iPhone, Android etc.)

    Academic research has areas where not much research has been done previously including the qualitative research on work/life balance, positive crossover of work/life balance, newness of Smartphone technology, and consequences of constant connectivity. This study hopes to eliminate some of the gaps in these areas of research and proposes two research questions:  So what does owning a Smartphone mean for work life and home life?  Most importantly can this phone help people towards or assist with the balance they are so looking for or do the phones not impact this balance and just assist in the work life and home life realms separately?

    A qualitative approach using constructionist and interpretivist views were used to conduct the research. Empirical material was collected during phone interviews with participants in the USA, while supporting material was gathered from conference papers, academic articles, websites, and textbooks.

    There are two major themes within this paper, work/life balance and Smartphone technology. For work/life balance a common understanding was reached that work and personal life should be kept happy but that doesn’t mean equal.  Also discussed is research about people that put up boundaries in their lives to try and separate things, one group of people likes to have work and personal separate but one group likes them combined.  Research also presents that there are consequences for setting up boundaries but that having the ability to choose where these boundaries are makes for a much happier situation.  On the technology side of research there is support for these devices being used to manage people’s different selves through communication from being more connected to people to feeling left out when the technology is not there. Also mentioned is how people adapt the devices to fit new and unique situations that the devices may not have been intended to be used for.

    Designing an Interactive Video Editing Tool for Teachers2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to find the answers to how an online interactive video editing tool for teachers to use would be designed. To find out the answers to this, students studying to become teachers and experienced teachers were interviewed and used for observations and usability testing of a prototype. In total there were 27 unique data gathering situations with 11 unique participants. The five teacher students who were participating were all teacher students at Linnaeus University in Växjö. The six experienced teachers have been teaching for many years and are currently lecturing teachers about new technology that can be used in the classroom. The result from interviews, observations and literature search contributed to a list of requirements which in turn became a prototype. What has been discovered is that teachers need a tool which is easy to use with interactions and functions such as adding clickable annotations to clips and creating playlists which will help teachers plan ahead and save time during lectures.

    Abstract [de]

    Immer mehr Familienangehörige leben in der heutigen Zeit voneinander getrennt. Durch weite Entfer-nungen zueinander ist die Gefahr besonders hoch, dass der Kontakt zu einem reinen Informations-austausch ohne gemeinsames Erleben abflacht. In diesem Paper wird ein Konzept vorgestellt, das Fa-milienmitglieder durch ein verteiltes Spiel verbindet trotz räumlicher Trennung. Dazu werden über einem Touchtisch und einem Bildschirm auf Seite einer älteren Person und einem normalen PC oder Tablet auf Seite der Angehörigen eine Verbindung mit Videotelefonie aufgebaut und dadurch die Spie-ler gegenübergestellt. Eine Anwendung ermöglicht es beiden Gruppen, ein einfaches Gesellschafts-spiel, wie z. B. Mensch-ärgere-dich-nicht, miteinander zu spielen. Beim Design der beiden grafischen Benutzeroberflächen werden die Bedürfnisse beider Nutzergruppen beachtet.

    Scan me – Ökad säkerhet med multifactor authentication: En undersökning om effekten vid ökad säkerhet i digitala identifierare2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The following bachelor thesis examines an application based on three factors: security, usability and functionality. The work presents a prototype of an identification application that uses QR codes to identify a person. The identification process is supposed to work in eg a line to a pub. The QR-code is in the guest's mobile and the doorman uses the prototype, which this thesis presents, on a tablet or smartphone and scan the guest's QR code. The aim is to investigate how the usability and functionality is affected in an application when it is added a factor that increases the apps security. This is examined through a user test where 8 test subjects will test the developed prototype and provide feedback both from a guest and a doormans perspective.

    The results show that the usability decreases while the security increases. The identification with the QR reader takes about 4 seconds longer than it does to identify with the usual method, i.e. comparing an ID card with a membership card. The functionality in the system increases because we add the functionality to scan a QR-code and compare it's information with a database. The prototype that has been developed in this bachelor thesis has development potential and can be used in other contexts and in other environments; for example the prototype would work equally well in a business context in which the business can replace their membership card with a QR code and a reader to give their customers benefits.

    Crowdsourcing for Information Visualization: Promises and Pitfalls2017In: Evaluation in the Crowd: Crowdsourcing and Human-Centered Experiments / [ed] Daniel Archambault, Helen Purchase, and Tobias Hoßfeld, Springer Publishing Company, 2017, p. 96-138Chapter in book (Refereed)
    Abstract [en]

    Crowdsourcing offers great potential to overcome the limitations of controlled lab studies. To guide future designs of crowdsourcing-based studies for visualization, we review visualization research that has attempted to leverage crowdsourcing for empirical evaluations of visualizations. We discuss six core aspects for successful employment of crowdsourcing in empirical studies for visualization – participants, study design, study procedure, data, tasks, and metrics & measures. We then present four case studies, discussing potential mechanisms to overcome common pitfalls. This chapter will help the visualization community understand how to effectively and efficiently take advantage of the exciting potential crowdsourcing has to offer to support empirical visualization research.

    Social IT support kontra traditionell IT support: Användarens syn på att söka IT support via sociala medier2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sociala medier och IT support, två områden som det ofta pratas om. Allt fler företag väljer att kombinera dessa två och låta sina kunder kontakta dem då de behöver IT support via sociala medier, detta fenomen kallas ’Social IT support’. Många människor, använder dagligen sociala medier dock är det oklart vad användare anser om att söka IT support via sociala medier. Denna uppsats syftar till att undersöka hur användaren ser på att söka IT support via sociala medier samt vid vilket tillfälle de hellre skulle använda sig av traditionell IT support så som telefon och e-post samt om användaren förräntar sig snabbare respons från företaget då de söker IT support via sociala medier. Undersökningarna som genomförts har syftat till att undersöka och granska vad verkliga individer tycker och tänker kring ämnet. Undersökningarna som genomfört har bestått av en strukturerad kvantitativ enkät med 102 respondenter samt en semi strukturerad kvalitativ intervju som har genomförts på fem individer. Resultatet som framkommit av undersökningen visar att majoriteten av respondenterna är positivt inställda till att prova på att söka IT support via sociala medier. Undersökningen visar också att det är de olika problemen som uppstår som påverkar om de väljer att söka IT support via sociala medier eller på det traditionella sättet. Resultatet visar även att de flesta respondenter förväntar sig snabbare kontakt från företaget då de sökt IT support via sociala medier än över telefon. Vilket är känt från tidigare forskning dock har skillnader från tidigare forskningar påträffats. Undersökningen visar även att män har högre förväntningar än kvinnor på hur lång tid det ska ta för ett företag att kontakta dem.

    "I know it when I see it" - Perceptions of Code Quality ITiCSE'17 Working Group Report2017In: ITICSE-WGR'17: PROCEEDINGS OF THE 2017 ITICSE CONFERENCE WORKING GROUP REPORTS, ACM Publications, 2017, p. 70-85Conference paper (Refereed)
    Abstract [en]

    Context. Code quality is a key issue in software development. The ability to develop high quality software is therefore a key learning goal of computing programs. However, there are no universally accepted measures to assess the quality of code and current standards are considered weak. Furthermore, there are many facets to code quality. Defining and explaining the concept of code quality is therefore a challenge faced by many educators. Objectives. In this working group, we investigated code quality as perceived by students, educators, and professional developers, in particular, the differences in their views of code quality and which quality aspects they consider as more or less important. Furthermore, we investigated their sources for information about code quality and its assessment. Methods. We interviewed 34 students, educators and professional developers regarding their perceptions of code quality. For the interviews they brought along code from their own experience to discuss and exemplify code quality. Results. There was no common definition of code quality among or within these groups. Quality was mostly described in terms of indicators that could measure an aspect of code quality. Among these indicators, readability was named most frequently by all groups. The groups showed significant differences in the sources they use for learning about code quality with education ranked lowest in all groups. Conclusions. Code quality should be discussed more thoroughly in educational programs.

    Region Jönköpings arbete med kvalitetsregistret Senior Alert: Hur ser användandet av kvalitetsregistret Senior Alert ut och kan rutiner och arbetsprocessen komma att påverka användandet?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Följande kombinerade studie är gjord på Region Jönköping tillsammans med kvalitetsregistret Senior Alert. Eftersom Senior Alert har en upplevelse att registret inte används i den utsträckning de själva önskar ville de ta reda på om detta var en sanningsenlig upplevelse och vad det i så fall fanns för orsaker till detta.

    Studien startade med en kvalitativ studie för att sedan skapa en bredare förståelse genom en kvantitativ enkät för att slutligen återigen göra en kvalitativ intervju med användare av registret för att skapa en djupare förståelse.

    Resultaten visade på att registret hade ett antal nyckelpunkter som kom att bli väsentliga för hur den teoretiska grunden och diskussionen skulle komma att utformas. Dessa nyckelord är Rutiner och arbetsprocess, Ledarskap, Utbildning och lärande samt Ålderns betydelse. Som senare kom att diskuteras i förhållande till tidigare forskning samt de valda teorierna, Sensemaking theory och Mintzbergs samordningsmekanismer. Detta kunde konstateras vara sådant som skulle kunna utvecklas för att göra användningen av registret samt innehållet mer komplett.

    Utifrån detta kan slutsatsen konstateras vara att det krävs en högre grad av samordning, tydligare ledarskap och mer utbildning inom Senior Alert och dess funktioner. Detta för att skapa mer kunskap och uppfylla Senior Alerts syfte att kunna föra pålitlig statistik på den information som samlas in och hämtas ur registret.

    Digitalt spelande med head-mounted display- och traditionell bildskärmsteknik: En komparativ studie av spelares rörelse- och synbeteende i den virtuella världen2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this thesis the behaviours of players in virtual environments using modern HMD VR technology and traditional 2D monitors is studied and compared. By developing a game prototype in 3D using a first-person perspective and placing it in the puzzle genre by having the players goal being that they must find an object in different rooms a comparative study has been carried out. The game prototype was developed by using prototyping and an alpha version was tested before the final version was completed.

     

    Two groups of 7 in each one has performed the test. One group used the HMD VR headset Oculus Rift DK2 and the other one used a traditional 2D monitor. Mouse and keyboard was used for controls. A data logging ran in the background of every test and collected information on the players positional and rotational data. The data was analysed and then compared between the two groups.

     

    In conclusion, there is no strong difference between the two groups. The biggest difference was in how much ground the players covered. The group who played in VR didn’t walk around and explored as much and instead was more stationary. But they were around 5 seconds faster in average. The group who played without VR looked up and down a bit more but the difference was never more than just 5 degrees.

    Applying the ATAM to an architecture for decentralized control of a transportation system2006In: Quality of Software Architectures, ISSN 0302-9743, Vol. 4214, p. 180-198Article in journal (Refereed)
    Abstract [en]

    For two years, we have been involved in a challenging project to develop a new architecture for an industrial transportation system. The motivating quality attributes to develop this innovative architecture were flexibility and openness. Taking these quality attributes into account, we proposed a decentralized architecture using multiagent systems (MASs). A MAS consists of multiple autonomous entities that coordinate with each other to achieve decentralized control. The typical advantages attributed to such decentralized architecture are flexibility and openness, the motivating quality attributes to apply MAS in this case. The Architecture Tradeoff Analysis Method (ATAM) was used to provide insights wether our architecture meets the expected flexibility and openness, and to identify tradeoffs with other quality attributes. Applying the ATAM proved to be a valuable experience. One of the main outcome of applying the ATAM was the identification of a tradeoff between flexibility and communication load that results from the use of a decentralized architecture

    Composition of architectural models: Empirical analysis and language support2010In: Journal of Systems and Software, ISSN 0164-1212, E-ISSN 1873-1228, Vol. 83, no 11, p. 2108-2127Article in journal (Refereed)
    Abstract [en]

    Managing the architectural description (AD) of a complex software system and maintaining consistency among the different models is a demanding task. To understand the underlying problems, we analyse several non-trivial software architectures. The empirical study shows that a substantial amount of information of ADs is repeated, mainly by integrating information of different models in new models. Closer examination reveals that the absence of rigorously specified dependencies among models and the lack of support for automated composition of models are primary causes of management and consistency problems in software architecture. To tackle these problems, we introduce an approach in which compositions of models, together with relations among models, are explicitly supported in the ADL. We introduce these concepts formally and discuss a proof-of-concept instantiation of composition in xADL and its supporting tools. The approach is evaluated by comparing the original and revised ADs in an empirical study. The study indicates that our approach reduces the number of manually specified elements by 29%, and reduces the number of manual changes to elements for several realistic change scenarios by 52%.

    View composition as a first-class concept in architectural descriptions2007Conference paper (Refereed)
    Abstract [en]

    Our position is that architectural descriptions lackcomposition of views, preventing a proper separation of concerns.This position took shape from experiences with buildingseveral complex distributed software systems. Our claim is thatview composition should be a first-class entity in architecturaldescriptions. As a first step, we propose an extension of the conceptualmodel of IEEE Recommended Practice for ArchitecturalDescription of Software-Intensive Systems with view composition.

    Specification, Planning, and Execution of QoS-awareGrid Workflows within the Amadeus Environment2008In: Concurrency and Computation, ISSN 1532-0626, E-ISSN 1532-0634, Vol. 20, no 4, p. 331-345Article in journal (Refereed)
    Abstract [en]

    Commonly, at a high level of abstraction Grid applications are specified based on the workflow paradigm. However, majority of Grid workflow systems either do not support Quality of Service (QoS), or provide only partial QoS support for certain phases of the workflow lifecycle. In this paper we present Amadeus, which is a holistic service-oriented environment for QoS-aware Grid workflows. Amadeus considers user requirements, in terms of QoS constraints, during workflow specification, planning, and execution. Within the Amadeus environment workflows and the associated QoS constraints are specified at a high level using an intuitive graphical notation. A distinguishing feature of our system is the support of a comprehensive set of QoS requirements, which considers in addition to performance and economical aspects also legal and security aspects. A set of QoS-aware service-oriented components is provided for workflow planning to support automatic constraint-based service negotiation and workflow optimization. For improving the efficiency of workflow planning we introduce a QoS-aware workflow reduction technique. Furthermore, we present our static and dynamic planning strategies for workflow execution in accordance with user-specified requirements. For each phase of the workflow lifecycle we experimentally evaluate the corresponding Amadeus components.

    Abstract [en]

    This bachelor thesis is a case study about cloud computing and specifically on finance applications. We have found out the reasons why not more small business owners moves to web-based solutions, since today it´s very popular to work in the cloud. Cloud services are a relatively new way of working and that means big changes for businesses while offering more opportunities than before. The purpose of this essay is to highlight the reasons why not more business owner’s uses web solutions and what benefits there are with web solutions. Our investigation is directed only into themselves against financial applications but can most likely be used in a more general context. To carry out the research we have used a case study where we have interviewed several users to the each approaches. The approaches we have investigated are desktop applications and web-based applications. The results after our data collection reveals a number of factors that play a large role in the choice between the different modes. Our survey shows that many users are afraid of what the cloud is and where their information actually goes. The result is also in on several advantages of web solutions, including that it is better availability and cost.

    Från förberedelse till upplevelse: Hur användarupplevelsen i e-handel kan efterlikna upplevelsen från en fysisk butik med fokus på single brandföretag2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose

    The purpose of this study was to examine which aspects of experience that consumers experience in a physical single brand store that should be emulated and lifted into the same corporate digital store. It has also been to see how well companies communicate their core values to their consumers in the physical store. Finally, I examined what’s important when it comes to features, functions, and generally experience for consumers when shopping online in general.

    Research questions

    What makes this study particularly interesting is that the single brand companies in this study have a physical and digital store where they sell their products, but they also have resellers who sell the same products and thus becomes their competitors. Since these single brand companies have a brand quality and core values that they need to live up to, they can’t reduce the prices of their products in the same way their retail stores do. Would the solution be to try to simulate the experience consumer’s get in the physical store into the digital store to convey a good brand experience?

    Conclusion

    This study was based on a model that describes how a good user experience can be created. The results have shown that companies need to work more with the user experience in their digital store. They could achieve this by working more actively with their consumers and try to understand who they are and how they look at their brand. Based on the outcome, work more actively to meet their consumer’s goals but also their own goals.

    Lastbalanseringsalgoritmer: En utvärdering av lastbalanseringsalgoritmer i ett LVS-kluster där noderna har olika operativsystem2012Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    This report covers an investigation of different load balancing algorithms in Linux Virtual Server. The investigation was done in a web cluster (with Apache as the software being used) consisting of three heterogeneous nodes, where the operating system was the detail that differentiated the nodes. The operating systems that were used in the investigation were Windows Server 2008 R2, CentOS 6.2 and FreeBSD 9.0. The factors examined were average response time at different load and how many connections the cluster could cope with, these factors were examined by measurements taken with the tool httperf.

    The investigation gives an answer to how a heterogeneous web clustersaverage response time and working capacity can be affected by the choice of load balancing algorithm. The result shows that the average response time stays low until a sudden rise occurs. Shortest Expected Delay and Weighted Least-Connection Scheduling could handle the largest number of connections.

    Information literacy and informed learning: conceptual innovations for IL research and practice futures2017In: Journal of Information Literacy, ISSN 1750-5968, E-ISSN 1750-5968, Vol. 11, no 1, p. 4-22Article in journal (Refereed)
    Abstract [en]

    Our paper draws together conceptual innovations emerging from the work of a group of researchers focussed on the relational approach to information literacy, more recently labelled ‘informed learning’. Team members have been working together in various configurations for periods ranging from seven to seventeen years. Our collaborative approach continues to yield new concepts and constructs which we believe to be of value to ongoing research and practice. Some of the ideas discussed have been previouly published, while others are being put forward for the first time. All are significant in that they together form new constructs that have emerged from a focus on the relational approach to information literacy. In this paper, Christine Bruce introduces the background to this work and the contributing researchers. Then the individual authors present the key directions which they have developed and are leading, typically working with one or more of the wider network. The key ideas presented are: The expressive window for information literacy (Mandy Lupton); information experience design (Elham Sayyad Abdi); cross-contextuality and experienced identity (Andrew Demasson); informed learning design (Clarence Maybee); spaces for inclusive informed learning (Hilary Hughes); and informed systems (Mary Somerville and Anita Mirjamdotter).  In each piece, authors reflect on what the idea is about, where it came from and what it might mean for research and practice.

    Push-teknik på webben2010Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study deals with push technology, a technology to send real-time data within web applications.

    Many times in today's more inter-active web an alternative way of processing data may be needed. Because of this, the topic seemed relevant in the context of web development.

    The aim is to examine how far this technique contrasts with other techniques to transport data. To investigate the push technology an application was created using a framework for this purpose. As a framework for the exercise the APE framework, containing a complete solution for push technology on the web, was chosen.

    As a basis for the report a gaming application was developed and a number of performance tests as well as an evaluation of the framework APE were made.

    Abstract [en]

    The following bachelor thesis examines different visualization techniques to view publication patterns and time publication patterns. A prototype is created to test if two different visualization techniques are appropriate for displaying publication patterns between universities, authors and journals; the two visualization techniques that are used are Sankey Diagram and Forced Direct Layout. Users can also investigate time publishing patterns, if you only want to see publications published between certain years.

     

    The result shows that with a large amount of data, both Sankey Diagrams and Forced Direct Layout are not quite suited to display publishing patterns, which was what 10 out of 10 test subjects said in the usability test. Sankey Diagram was able to structure data more than Forced Direct Layout, getting all the patterns and publications in a vertical list while in Forced Direct Layout ended up more compact. However, you can get a better overview of all patterns and publications with Forced Direct Layout to make all publications fit on a page, with Sankey Diagram you have to scroll back and forth to see the full visualization. If you want to create a visualization with a lot of data, there are several interaction techniques and filter options to be added, to reduce what shows in the visualization. The results for time publishing patterns are hard to convey anything concrete because the data used in this work was not complete.

    Abstract [en]

    The existence for companies today consists of constant challenges with customers that want more individual products with high quality as quickly as possible. For a company to be able to have a short delivery time, it must also have a short production time. This makes streamlining and improvement of processes a big part of a company’s work

    This thesis has been carried out together with the company Lasermax Roll Systems AB, a world-leading manufacturer of feeding, finishing and monitoring systems for high-speed digital printers. They manufacture their products according to the assembling for costumer order principle.

    The purpose with this thesis is to map and analyze, the assembling process and the test process at Lasermax Roll Systems AB. The mapping of the processes shall result in flowcharts and identifying problems in the processes, which can be used for working with improvements.

    The information for the result has been gathered by interviews of key persons in the processes and studies of existing information at Lasermax Roll Systems AB. Later on the empirical information has been analyzed by comparing with literature from the theoretical part.

    The thesis resulted in flowcharts over the production processes, assembling and test. Also three problem areas were identified which can be used for working with improvements. The three areas are: items and suppliers, control of review and testing of the products.

    Conclusions of this thesis are that working with mapping of processes is very good för companies today to become more effective and improve their business. It is also important for the companies to see the overall picture of their business and work with it, from suppliers to the costumer, together, to be able to deliver a product on time with good quality.

    Communicate to Win: Real-time communication services for location-based learning activities2017Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    In recent years, mobile devices have become an integral part of our everyday life in various fields. The technology that powers them is used in various devices, such as smartphones, tablets, and PDAs. These devices hold extensive computation capabilities, along with advanced communication abilities, which are supported by an internet connection and diverse types of motion and location sensors. Mobile devices have changed the way people communicate with each other, for example by providing options to send instant text messages, perform live video calls with others in addition to voice conversations. These capabilities have encouraged educators to exploit mobile technology and promote new types of learning options. There are several new learning possibilities based on tools such as mobile dedicated applications, location-based learning activities, and interactive social related tasks. These new uses require adjustments to educational programs to allow support for this type of learning. The uniqueness of mobile learning, in contrast with the classic learning paradigm, is the ability to connect the learner through enhanced learning materials to the outside environment. This breaks the physical borders that exist in the traditional classroom and creates new learning possibilities, but it has its drawbacks. One of the difficulties that arise from this type of learning is the loss of contact in real time between teacher and student, especially when performing outdoor activities. The Treasure-HIT platform was conceived to create outdoor Treasure Hunt-based games, mainly for educational purposes, by introducing an authoring web platform and a supporting mobile application. The platform includes communication capabilities based on social interactions and cooperative learning with the integration of social networks, and yet real-time educator and student communication is still lacking. Adding real-time communication features provides a way to better support ongoing learning activities, and can take pressure off the learning process for the students, by providing them with a more personal experience and immediate support when needed. This thesis follows the process of addressing this concern in TreasureHIT, including the rationale, the background, the possible options and gradual development of a prototype solution to the problem under the existing Treasure-HIT infrastructure. In the thesis, the advantages of two features are explored: (1) the Realtime Group Tracking Map, which provides a way to monitor the movement and action of groups of players during game time, and (2) Instant Text Messaging service, which allows the game instructor to send custom text messages to the different game groups. The research findings indicate that the new monitoring options provide a solid tool for real-time analysis of the progress of the game and the ability to inform about various issues and solve them in real time. ii Furthermore, the instant message service feature received positive responses from the game-manager and players alike, on the grounds of major improvements to the general game flow and problem solving in real-time.

    Abstract [en]

    The amount of information has increased as a result of the technological development and it has become common to perceive information overload. This area is researched in office environments, however, we found no research in telecommuting. Low quality of information has been found through previous research as being one of the main reasons why we are experiencing information overload. In previous research, students were able to conclude that there was no research on the office and telecommuting experienced information overload. This study's problem is based on a scientific problem, were the students intended to examine how work in offices are perceived compared to teleworking in aspects of information quality and information overload. To illustrate the problem a qualitative method was selected. The study is based on semi-structured telephone interviews with five participating informants. This study's found that office environments contributed with more irrelevant information because of verbal communication. The students also came to the conclusion that the concepts of information quality and information overload are related to each other, but information quality is the overlying concept. Lack of information quality contributes to experienced information overload.

    Software Engineering for Smart Cyber-Physical Systems - Towards a Research Agenda: Report on the First International Workshop on Software Engineering for Smart CPS2015In: Software Engineering Notes: an Informal Newsletter of The Specia, ISSN 0163-5948, E-ISSN 1943-5843, Vol. 40, no 6, p. 28-32Article in journal (Other academic)
    Abstract [en]

    Cyber-Physical Systems (CPS) are large interconnected softwareintensivesystems that influence, by sensing and actuating, thephysical world. Examples are traffic management and power grids.One of the trends we observe is the need to endow such systemswith the “smart” capabilities, typically in the form of selfawarenessand self-adaptation, along with the traditional qualitiesof safety and dependability. These requirements combined withspecifics of the domain of smart CPS – such as large scale, the roleof end-users, uncertainty, and open-endedness – render traditionalsoftware engineering (SE) techniques not directly applicable; makingsystematic SE of smart CPS a challenging task. This paperreports on the results of the First International Workshop on SoftwareEngineering of Smart Cyber-Physical Systems (SEsCPS2015), where participants discussed characteristics, challenges andopportunities of SE for smart CPS, with the aim to outline anagenda for future research in this important area.

    Abstract [en]

    Cyber-physical system (CPS) have been recognized as a top-priority in research and development. The innovations sought for CPS demand them to deal effectively with dynamicity of their environment, to be scalable, adaptive, tolerant to threats, etc. -- i.e. they have to be smart. Although approaches insoftware engineering (SE) exist that individually meet these demands, their synergy to address the challenges of smart CPS (sCPS) in a holistic manner remains an open challenge. The workshop focuses on software engineering challenges for sCPS. The goals are to increase the understanding of problems of SE for sCPS, study foundational principles for engineering sCPS, and identify promising SE solutions for sCPS. Based on these goals, the workshop aims to formulate a research agenda for SE of sCPS.

    Applying Artificial Neural Networks to Reduce the Adaptation Space in Self-Adaptive Systems: an exploratory work2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Self-adaptive systems have limited time to adjust their configurations whenever their adaptation goals, i.e., quality requirements, are violated due to some runtime uncertainties. Within the available time, they need to analyze their adaptation space, i.e., a set of configurations, to find the best adaptation option, i.e., configuration, that can achieve their adaptation goals. Existing formal analysis approaches find the best adaptation option by analyzing the entire adaptation space. However, exhaustive analysis requires time and resources and is therefore only efficient when the adaptation space is small. The size of the adaptation space is often in hundreds or thousands, which makes formal analysis approaches inefficient in large-scale self-adaptive systems. In this thesis, we tackle this problem by presenting an online learning approach that enables formal analysis approaches to analyze large adaptation spaces efficiently. The approach integrates with the standard feedback loop and reduces the adaptation space to a subset of adaptation options that are relevant to the current runtime uncertainties. The subset is then analyzed by the formal analysis approaches, which allows them to complete the analysis faster and efficiently within the available time. We evaluate our approach on two different instances of an Internet of Things application. The evaluation shows that our approach dramatically reduces the adaptation space and analysis time without compromising the adaptation goals.
