    Agil Systemutveckling: En studie av kravhantering och beställarroll i agila angreppsätt2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper is a degree project on the C-level, 15 points at University West, Department of Business and IT dept. Informatics. This study is about agile methodology and its impact on IT projects. Requirements management is a process within an IT project, where customer has certain requirements that must be met by an IT system. The difference between the traditional and agile development is in the requirements management process and it can cause problems in a project. Requirements change during IT projects and to manage requirements, agile principles apply. Specification and planning in the waterfall model is time consuming. Working agile means to have close contact with the client. This minimizes the risk of project failure. With agile methods, functions can be developed at a faster rate and the customer receives prompt delivery. There are currently several different methods for systems development and project management. Some are based on research, others are new and some have been around a long time in the IT world. This work has identified customer involvement; Risk Reduction and Delivery which contribute to several projects fail under traditional systems. Agile methods are flexible, agile and welcome change and the customer will be able to steer the project. Agile methods have however provided the opportunity for developers to more quickly deliver functionality to the customer.

    Fria och öppna programvaror inom kommunal verksamhet: Vägen mot öppna standarder?2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report deals with the attitudes within municipalities of open source software and open standards and if open source software may be an option to gain open standards. The aim has been to find out if open source software and open standards would be able to solve the lock-in problems that municipalities have against proprietary software. The study is conducted as an exploratory, inductive and qualitative study with depth interviews of subjectively selected informants as data collection method. A literature review has also been implemented by the relevant books and articles. Some economic determinants of municipalities to make use of open source software have not been considered in this study. The informants used in this study are all IT managers in a Swedish municipality and our key informants have been selected in a subjective manner based on the expertise they have in the subject. The conclusions drawn were that municipalities have been difficult to define standards and open standards, and that they do not automatically see the connection between open standards and open software. They also see different areas of interest for standardization.

    Sociomateriality and design – How do we un-pack technology for knowing in practice?: Research in Progress/Workshop2016Conference paper (Other academic)
    Abstract [en]

    Blended e-learning permeates flexibility and school is no longer the only place for learning, rather through e-learning courses new ways of building competences throughout life and integrated in the workplace can be accomplished. Technological artifacts, the material itself do not create learning,rather, social and pedagogical aspects from a participatory perspective in e-learning courses is needed to balance the impact of technology. Challenges to reach balance between material and social is in this paper illustrated as a sociomaterial learning practice through a work-integrated e-learning (e-WIL) project between a university and collaborating manufacturing industries. This learning practice comprise design of e-learning courses, target industry knowledge needs to reach for being a competent employee. Teachers' and course participants' activities show various challenges of work integrated e-learning. Early results from focus group sessions and observations are categorized as knowing-how to design and use digital learning technology, knowing-what knowledge to be learnt for work practice and knowing-when to use new knowledge in work practice.

    Work-Integrated Learning and Co-creation of Knowledge: Design of collaborative technology enhanced learning activities2014In: Proceedings of the 37th Information Systems Research Seminar in Scandinavia (IRIS 37) / [ed] Ahmad Ghazawneh, Jacob Nørbjerg and Jan Pries-Heje, Ringsted, 2014, p. 1-15Conference paper (Refereed)
    Abstract [en]

    In this paper we aim to understand management’s perceptions of knowledge and competence development to inform the design of technology enhanced learning activities integrated in the workplace. Work-integrated learning can be viewed with the university lens on studies of formal education integrated in the workplace setting, but here we rather emphasize the conditions of the workplace as implications for design of successful e-learning initiatives. We conducted interviews with 15 manufacturing industries in Sweden and used qualitative content analysis approach to interpret the text data. Results show that companies describe a rich variation of work-integrated learning activities, but the step towards external collaboration with academia for co-production of knowledge is marginal. Also, broad-minded work for innovations is limited. This imply the need for well-planned design of richer collaborative acitivites between academia and organizations through use of media technology to encourage competence development.

    Learning Aspects for Manufacturing Enterprises within Aerospace industry entering into Quality Standard AS91002011In: 24th ICDE World Conference on Open and Distance Learning: Expanding Horizons- new approaches to ODL, 2011, p. 1-11Conference paper (Refereed)
    Abstract [en]

    The aerospace industry is expected to grow substantially during the next two decades. As a result more suppliers aim for entering into this industry. Demands on safety and quality in this sector are particularly high, where SME´s must upgrade from the generic group of quality standards, the ISO9000 family, to AS9100, the aerospace standard. In this research we focus on the meaning of learning processes for successful implementation of quality standards in a workplace context at a manufacturing company. By using Blooms Revised Taxonomy of learning, we can understand, evaluate and design actions for continuous improvement which can be supported by an IT-based tool for self-assessment supporting organisational learning and implementation of the Quality Management System.

    En mobil evenemangsapplikation i Trollhättans utveckling mot en mer attraktiv stad2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this study, a prototype of a mobile application that collects local event information, has been created. Local events are a contributing factor to increased economic growth and how individuals experience a city as a whole. Because of this, it is vital that information about local events reaches inhabitants. This information is currently distributed in both social media, websites, newspapers and bulletin boards. Due to the fact that the information is currently scattered, inhabitants in the city feel that they are not reached by all information about local events. The aim of the study is to develop a design proposal on a mobile application that can be used in future development and implementation of the application. Through qualitative interviews with students at the University of West, a need for an event application has been identified, proposals for features and content have been developed. Based on these interviews and previous research within areas of usability, user experience, design principles and interaction design a prototype has been designed. To confirm that the prototype produced was considered useful and had good usability five structured usability tests were performed with potential end users. The result of these shows that the study has developed a useful interface and that the general perception of both the interface and the application was its simplicity. The conclusion of the study is that the designed prototype is appropriate and useful which will enable the interface to be used as a basis for future development of the application.

    SQL vs NoSQL: En prestanda jämförelse2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this paper we compare the performance of a NoSQL database and a MySQL database. The execution time is measured for a variety of different operations, such as read, write and update. We will also perform tests on a denormalized MongoDB database when the tests uses more than one collection. A small amount of structured data is used to model a fictive taxi company. The tests are written in Python and are performed in a virtual environment. The paper goes through the history behind relational databases and NoSQL types, and also covers both MySQL and MongoDB, which is the database managers used in these tests. They are chosen because they are the most popular on the market. Results show that MongoDB is quicker than MySQL when the operations are performed on a single collection/table.

    De formade ögonbrynens ilska: Queer coding inom Disneys porträttering av manliga skurkar2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to examinehow and what Disney communicate to their target audience, by analyzing the four animated feature films Peter Pan (1953), The Lion King (1994), Pocahontas (1995), and Princess and the Frog (2009). The animated movies have been analyzed through a qualitative method to get a better understanding of how Disney portray their male antagonists through queer coding. Through semiotics, and Peter Dahlgren's approach to analyzing media texts, we have gained a deeper understanding of what Disney is communicating. The study shows that there are many obvious cases of queer coding because of the stereotypically feminine way that the male villains are portrayed. The villains show signs of this femininity through everything from facial features to bodily movements. Through this detailed analysis it has come to our attention, that there is no doubt that the villains are being portrayed in a much more feminine way in comparison to the remaining characters in the movies.

    Encrypted media streaming over 4G (LTE) with Raspberry Pi2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to explore the possibility of building a more secure and better streaming solution than publically available. The available solutions today are in our opinion mediocre in quality and are often missing older and unknown artists. A prototype will be built and tested in a variety of different scenarios where the prototypes capability will be tested to the fullest. The result is a working streaming solution where good quality and security is a fact. The finished prototype has a few limitations, but overall it's a good working solution.

    Critical Imaginaries and Reflections on Artificial Intelligence and Robots in Postdigital K-12 Education2019In: Postdigital Science and Education, ISSN 2524-485X, Vol. 1, no 2, p. 427-445Article in journal (Refereed)
    Abstract [en]

    It is commonly suggested that emerging technologies will revolutionize education. In this paper, two such emerging technologies, artificial intelligence (AI) and educational robots (ER), are in focus. The aim of the paper is to explore how teachers, researchers and pedagogical developers critically imagine and reflect upon how AI and robots could be used in education. The empirical data were collected from discussion groups that were part of a symposium. For both AI and ERs, the need for more knowledge about these technologies, how they could preferably be used, and how the emergence of these technologies might affect the role of the teacher and the relationship between teachers and students, were outlined. Many participants saw more potential to use AI for individualization as compared with ERs. However, there were also more concerns, such as ethical issues and economic interests, when discussing AI. While the researchers/developers to a greater extent imagined ideal future technology-rich educational practices, the practitioners were more focused on imaginaries grounded in current practice.

    Changes in gravitational parameters inferred from time-variable GRACE data- A case study for October 2005 Kashmir Earthquake2016In: Journal of Applied Geophysics, ISSN 0926-9851, E-ISSN 1879-1859, Vol. 132, p. 174-183Article in journal (Refereed)
    Abstract [en]

    The earth's gravity changes are attributed to the redistribution of masses within and/or on the surface of the earth, which are due to the frictional sliding, tensile cracking and/or cataclastic flow of rocks along the faults and detectable by earthquake events. Inversely, the gravity changes are useful to describe the earthquake seismicity over the active orogenic belts. The time variable gravimetric data are hardly available to the public domain. However, Gravity Recovery and Climatic Experiment (GRACE) is the only satellite mission dedicated to model the variation of the gravity field and an available source to the science community. Here, we have tried to envisage gravity changes in terms of gravity anomaly (Δg), geoid (N) and the gravity gradients over the Indo-Pak plate with emphasis upon Kashmir earthquake of October 2005. For this purpose, we engaged the spherical harmonic coefficients of monthly gravity solutions from the GRACE satellite mission, which have good coverage over the entire globe with unprecedented accuracy. We have analysed numerically the solutions after removing the hydrological signals, during August to November 2005, in terms of corresponding monthly differentials of gravity anomaly, geoid and the gradients. The regional structures like Main Mantle Thrust (MMT), Main Karakoram Thrust (MKT), Herat and Chaman faults are in closed association with topography and with gravity parameters from the GRACE gravimetry and EGM2008 model. The monthly differentials of these quantities indicate the stress accumulation in the northeast direction in the study area. Our numerical results show that the horizontal gravity gradients seem to be in good agreement with tectonic boundaries and differentials of the gravitational elements are subtle to the redistribution of rock masses and topography caused by 2005 Kashmir earthquake. Moreover, the gradients are rather more helpful for extracting the coseismic gravity signatures caused by seismicity over the area. Higher positive values of gravity components having higher terrain elevations are more vulnerable to the seismicity and lower risk of diastrophism otherwise.

    Making sense of social media implementation: a longitudinal case study of the technological frames of hotel employees2017Conference paper (Refereed)
    Abstract [en]

    Social media has become an important part of people’s social life and effect how they communicate, interact and consume online. Social media, has therefore also to a great extent been adopted by organizations in order to be used both for internal and external communication. The purpose of this paper is to study the adoption and implementation of social media in hotel organizations from the employee’s, or user’s perspective by applying the concept of “technological frames” with focus on the nature of technology, technology strategy and technology in use. The paper is designed as a longitudinal, qualitative case study consisting of data collected in seven European countries. In total 28 in-depth interviews have been conducted during 2.5 years. Findings show that the employees’ technological frames to a high extent has been constructed outside the organization during their private usage, or non-usage of social media, and that these frames affect how they use social media in the hotel organizations. The contribution is an insight into how technologies, like social media that is introduced to employees outside the organizational setting, are used during an implementation process within the workplace. Keywords: social media, implementation, adoption, technological frames, social media marketing, usage, perception, hospitality,

    LAPSync: a Location-Aware Protocol for Remote File Synchronization2012Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Commercial provisioning of file synchronization services (FSS) relies entirely on protocols that utilize a remote central server that is often located in the cloud to host important files. Updates at user computers are propagated to the central server and from the central server to other sources in need of such updates. Therefore, a synchronization operation between two computers located on the same network often results in file data transmission to and from this local network at least twice. This introduces an unnecessary bandwidth usage on a user’s local network and has become an issue, especially since there is an increase in the demands for internet resources.

    This thesis work presents a new file synchronization protocol towards FSS known as LAPSync (location-aware protocol for remote file synchronization). This paper also proposes a hierarchical synchronization mechanism by utilizing LAPSync. Our proposed solution relies on the ability of LAPSync clients to acquire knowledge about the location of clients participating in the synchronization operation to construct a hierarchical synchronization path. Finally, we implement our protocol into a prototype and conduct experiments to compare with drop-box (a popular file synchronization service). The results obtained show that LAPSync offers a reduction in bandwidth usage when the files to be synchronized exist on the same local network

    Kommunikation för hållbar energianvändning i bostäder2019Report (Other (popular science, discussion, etc.))
    Abstract [sv]

    En effektivare användning av energi och minskat resursslöseri är viktigt för att begränsa klimatförändringar och arbeta mot en mer hållbar utveckling, inte minst inom bostadssektorn. Bostadens energianvändning är beroende av både de professionellas och hushållens agerande. I dag finns teknisk kunskap om hur vi utvecklar och producerar energieffektivaoch smarta energilösningar till bostäder och till den teknik som hushållen använder. Det finns också forskning om hur hushållen agerar och bör agera för att spara och effektivisera användningen av energi i hemmet. Ett mer angeläget problem är hur dessa grupper ska samverka med varandra så att energieffektivisering och besparing också genomförs. Det gäller såväl kommunikationen mellan professionella och hushåll, som de senares interaktion med den energiteknik som de professionella tillhandahåller.Syftet är att undersöka hur kommunikationen mellan professionella och hushåll kan utvecklas för att uppnå en hållbar energianvändning i bostäder. Rapporten baseras på en sammanställning av beteende- och samhällsvetenskaplig forskning som på olika sätt har behandlat kommunikation om energiteknik, energibesparing och effektivisering. Vi har även genomfört intervjuer med olika professionella aktörer vid ett energibolag. Avsikten har då varit att undersöka hur energibolaget kommunicerar om miljö- och energifrågor med hushållen. Vår bakgrundsförståelse utgår från tre olika kommunikationsstrategier; informations-, respons och medverkansstrategier, som grundar sig i delvis olika sätt att förstå vad kommunikationenmellan professionella och hushåll kan innebära.Resultatet från kunskapssammanställningen pekar på vikten av att, i kommunikationen med hushåll, utgå från deras egen energianvändning, energirelaterade vanor och val av energiteknik, liksom deras intresse och motiv till att spara energi. För att kommunikation om energifrågor ska upplevas som relevant och meningsfull för hushållen så räcker dock inte detta.Man bör även identifiera och/eller skapa adekvata tillfällen för kommunikation och sträva efter att budskapet liksom kommunikationen kan anses som trovärdig. För att nå fram är det också av vikt att tänka igenom hur man talar eller skriver om energifrågor, exempelvis att det som sägs och skrivs är tillräckligt begripligt. De professionellas kommunikation medhushållen sker även via tekniken. Att designa tekniken för god användbarhet och effektivare energianvändning är därför viktigt.Resultatet från intervjuerna med professionella aktörer på energibolaget VMEAB visar på olika former av kommunikationsaktiviteter såsom allmänt informationsmaterial som skickas till hushåll, digital kommunikation, reklam, evenemang och personlig kontakt. Intervjupersonerna lyfter fram vikten av att det som kommuniceras är begripligt för hushållen och att den information som ges ut varken är för omfattande eller knapphändig. Personlig kontakt medhushållen är eftersträvansvärt, men det är resursmässigt svårt att tillgodose. Energibolaget har en ambition att ytterligare utveckla kommunikationen med hushållen för att öka deras intresse och medvetenhet för energianvändningen. Insatser som då nämns är att synliggöra energianvändningen via en personlig hemsida, utveckla funktioner som ska ge direkt återkoppling mellan kund och bolag, samt se över möjligheten att vara mer informell i kommunikationen med hushållen.

    An mHealth artifact in home care: Professional progression through work integrated learning: Towards an IT supported caring conversations2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim is to study a problematic grocery-shopping situation within a home care organization, in one studied municipality in Sweden and for this, a qualitative action design research method is applied. As a solution to this problem, an mHealth (mobile health) artifact was developed and the thesis aims to study the developed solution and the WIL effects on the organization and the caring situation. The purpose is to emphasize on the perceptions of an mHealth artifact for the grocery shopping process as well as capture the early perceptions focusing on the values and effects for the different levels of engagement spanning the user groups involved. Then, finally investigating the effects on the caregivers’ competence development in relation to the mHealth artifact and the work integrated learning. This leads to the recognition of the need for a conversation between the caretakers and the caregivers. This results in the developed artifact, being found a conversational starter, nurturing and triggering a caring conversation, which leads to professional progression. This consequently, leads to higher quality of care and to the caregivers having more pride in their profession as well as having more time for the caretakers. This all concludes that technology will not replace caregivers. But caregivers, who use technology, will probably replace caregivers who don’t.

    Abstract [en]

    Every year businesses and individuals are exposed by Denial Of Service attacks with the intention of putting servers into disuse and make services unusable. We have investigated three different ways to protect a server and the internal network against Denial Of Service attacks in the most efficient manner. This study measure the CPU usage and response time before and during a DoS-attack to get an overview of how charged each unit is during an attack to compare each DoS-protection.

    The survey showed that the Cisco ASA Firewall protects the server and the internal network in the most efficient way because the device uses a deep packet filtering and inspection which involves a more advanced technology that is used to filter out inappropriate data-traffic

    Software architecture graphs as complex networks: a novel partitioning scheme to measure stability and evolution2007In: Information Sciences, ISSN 0020-0255, E-ISSN 1872-6291, Vol. 177, no 12, p. 2587-2601Article in journal (Refereed)
    Abstract [en]

    The stability and evolution of the structure of consecutive versions of a series of software architecture graphs are analysed using the theory of complex networks. Brief comparisons are drawn between the scale-free behaviour and second order phase transitions. On this basis a software design metric Icc is proposed. This software metric is used to quantify the evolution of the stability vs. maintainability of the software through various releases. It is demonstrated that the classes in the software graph are acquiring more out-going calls than incoming calls as the software ages. Three examples of software applications where maintainability and continuous refactoring are an inherent part of their development process are presented, in addition to a Sun Java2 framework where growth and backward compatibility are the more important factors for the development. Further to this a projected future evolution of the software structure and maintainability is calculated. Suggestions for future applications to software engineering and the natural sciences are briefly presented.

    The mechanics of charge-shift bonds: A perspective from the electronic stress tensor2011In: Chemical Physics Letters, ISSN 0009-2614, E-ISSN 1873-4448, Vol. 510, p. 18-20Article in journal (Refereed)
    Abstract [en]

    The mechanism of charge-shift bonding is discussed from the perspective of the electronic stress tensor. In charge-shift bonds, the tensile mode of the stress tensor (attraction of electrons to the nuclei) is stronger, relative to the compressive modes (attraction of electrons toward the bond axis) than in conventional covalent bonds. Similar bonding indicators based on the eigenvalues of the tensor of second derivatives of the electron density and bond metallicity measures also correlate with charge-shift binding. These indicators seem preferable to the electron-density Laplacian and the local energy density because they can distinguish between weak covalent bonds and charge-shift bonds.

    An investigation of the merging and collapsing of software2007In: Advances in Complex Systems, ISSN 0219-5259, Vol. 10, no 3, p. 379-393Article in journal (Refereed)
    Abstract [en]

    We explore the use of complex networks for understanding of the interaction of computer software applications written in the Java object-oriented language with the "library classes" that they use (those provided by the Java Runtime Environment) as, essentially, a merged network of classes. The dependence of the software on the library is quantified using a recently introduced model that identifies phases close to a second-order phase transition existing in scale-free networks. An example is given of a piece of software whose class network collapses without the presence of the library classes, providing validation of a novel structural coupling measure; Rcoupling. The structural properties of the merged software-Java class networks were found to correlate with the proportion of Java classes contained within the subset delimited by Rcoupling. A mechanism for the preservation of the software class network is also provided for the cases studied where the removal of the library classes does not cause collapse.

    The role of hydrogen bonding in nanocolloidal amorphous silica particles in electrolyte solutions2009In: Journal of colloid and interface science, ISSN 1095-7103Article in journal (Refereed)
    Abstract [en]

    Explicit solvent (water) molecular dynamics simulations were undertaken containing three pairs of amorphous silica nanoparticles, having diameters of 2.0nm, 2.4nm and 2.8nm, respectively. Mean forces acting between the silica nanoparticles were calculated in a background electrolyte, i.e., NaCl at four different concentrations. Dependence of the inter-particle potential of mean force on the center of mass separation, silicon to sodium ratio (Si:Na(+)), background electrolyte concentration, number of hydrogen bonds directly linking pairs of silica nanoparticles and the density of charged surface sites, are calculated. The pH was indirectly accounted for via the ratio of silicon to sodium used in the simulations. The close relationship between the variation of the number of hydrogen bonds between the pairs of silica nanoparticles and the inter-particle potential of mean force indicates that the degree of inter-particle hydrogen bonding quantifies, for a given size of nanoparticle, the degree of nanoparticle 'stickiness'. Simulations also show that the number of hydrogen bonds between the charged surface (O(-)) sites and the surrounding water molecules increases with increase in charged sites, in agreement with the interaction behavior of silica nanoparticles usually seen in experiments.

    Abstract [en]

    Explicit molecular dynamics simulations were applied to a pair of amorphous silica nanoparticles in aqueous solution, with diameter of 4.4 nm and with four different background electrolyte concentrations, to extract the mean force acting between the two silica nanoparticles. Dependences of the interparticle forces on the separation and the background electrolyte concentration were demonstrated. The nature of the interaction of the counterions with charged silica surface sites (deprotonated silanols) was investigated. A "patchy" double layer of adsorbed sodium counterions was observed. Dependences of the interparticle potential of mean force on the separation and the background electrolyte concentration were demonstrated. Direct evidence of the solvation forces is presented in terms of changes of the water ordering at the surfaces of the isolated and double nanoparticles. The nature of the interaction of the counterions with charged silica surface sites (deprotonated silanols) was investigated in terms of quantifying the effects of the number of water molecules separately inside each pair of nanoparticles by defining an impermeability measure. A direct correlation was found between the impermeability (related to the silica surface "hairiness") and the disruption of water ordering. Differences in the impermeability between the two nanoparticles are attributed to differences in the calculated electric dipole moment.

    Molecular dynamics simulation of nanocolloidal amorphous silica particles: part III.2009In: The Journal of chemical physics, ISSN 1089-7690, Vol. 130, no 13, p. 134702-Article in journal (Refereed)
    Abstract [en]

    Explicit-solvent molecular dynamics simulations were applied to four pairs of amorphous silica nanoparticles, two pairs having a diameter of 2.0 nm and two pairs with diameter 3.2 nm. The silica nanoparticles were immersed in a background electrolyte consisting of Ca(2+) and Cl(-) ions and water and mean forces acting between the pair of silica nanoparticles were extracted at four different background electrolyte concentrations. The pH was indirectly accounted for via the ratio of silicon to sodium used in the simulations. Dependence of the interparticle potential of mean force on the center-of-mass separation and the silicon to sodium ratio (5:1 and 20:1) is demonstrated. A Si:Na(+) ratio of 5:1 gave more repulsive interparticle potentials and lower numbers of internanoparticle or "bridging" hydrogen bonds. Conversely a Si:Na(+) ratio of 20:1 yielded more attractive potentials and higher numbers of bridging hydrogen bonds. The nature of the interaction of the counterions with charged silica surface sites (deprotonated silanols) was also investigated. The effect of the sodium double layer on water ordering was observed. The number of water molecules trapped inside the nanoparticles was investigated, and at the highest background ionic concentrations were found to consistently behave in accordance with there being an osmotic pressure. This study highlights the effect of divalent (Ca(2+)) background ions on the interparticle potentials compared with previous work using monovalent (Na(+)) background ions. Mechanisms of coagulation and the stability of silica nanocolloids found from this work appear to be in agreement with findings from experiments described in the literature.

    Spanning Set of Silica Cluster Isomer Topologies from QTAIM2011In: Journal of Physical Chemistry A, ISSN 1089-5639, E-ISSN 1520-5215, ISSN 1089-5639Article in journal (Refereed)
    Abstract [en]

    Structural and chemical properties of the building block of silica nanowires, (SiO2)6, are investigated with the theory of atoms and molecules (QTAIM). Twenty-five conformers have been analyzed, ten of which have not been reported before. We extend the silica (SiO2)6 topology phase space using QTAIM; the Poincare–Hopf topological sum rules are applied and used to identify the spanning set of topologies, and this includes finding eight new distinct topologies that satisfy the Poincare–Hopf relation. A simple phase diagram of the solutions of the Poincare–Hopf relation is created with the aid of a new classification scheme to determine the boundary between topological stability and instability. Sum rules are then found to be applicable to any set of isomers. We determine that O--O bonding interactions exist for the silica (SiO2)6 conformers in regions where the energy surface is flattest. In addition, we identify unstable local minima in the topology of the charge density in order to further compare conformer instabilities. We quantify the dimensionality of a molecule using the Poincare–Hopf relation instead of Euclidean geometry. This quantum topological definition of geometry shows that the four most energetically stable (SiO2)6 conformers are quantified as two-dimensional within the new quantum topology.

    Benefits of Alternative Network Topologies For COTS Linux Clusters2006In: Proceedings of the International Conference on Applied Computing: San Sebastian, Spain. Feb 25-28, 2006, p. 457-461Conference paper (Other academic)
    Abstract [en]

    The focus of this paper is to evaluate the use of two different network topologies for Ethernet networks in small Common

    Off The Shelf (COTS) clusters. The fully meshed network topology was evaluated and its impact on latency and

    bandwidth was measured and compared to the more traditional switched network topology. This was done at MPI level

    by measuring the point-to-point round trip latency (ping-pong) and all-to-alla bandwidth for different sized messages.

    The results from the experiments are presented and the overall the benefits and drawbacks of the both approaches are

    discussed.

    A Kenyan Cloud School: Massive Open Online & Ongoing Courses for Blended and Lifelong Learning2013In: Open Praxis, ISSN 2304-070X, Vol. 5, no 4, p. 301-313Article in journal (Refereed)
    Abstract [en]

    This research describes the predicted outcomes of a Kenyan Cloud School (KCS), which is a MOOC that contains all courses taught at the secondary school level in Kenya. This MOOC will consist of online, ongoing subjects in both English and Kiswahili. The KCS subjects offer self-testing and peer assessment to maximize scalability, and digital badges to show progress and completion to recognize and validate non-formal learning. The KCS uses the Moodle LMS with responsive web design to increase ubiquitous access from any device. Access is free and open, and the KCS intends to be a contextualized open educational resource for formal secondary institutions to support blended learning and a free source of non-formal education for lifelong learning. The expected outcomes are that this effort will reduce secondary school dropout rates, improve test scores, become a quality resource for blended learning, as well as validate and recognize lifelong learning in Kenya.

    Bridging the learning gap in Kenya with mobile learning: Challenges and future strategies2015In: Proceedings of E-Learn: World Conference on E-Learning in Corporate, Government, Healthcare, and Higher Education 2015 / [ed] curtis Ho & Grace Lin, University of Hawaii, USA, Chesapeake, VA: Association for the Advancement of Computing in Education, 2015, p. 1319-1325Conference paper (Refereed)
    Abstract [en]

    The overarching aim of this research was to study how mobile technology can catalyze informal learning and bridge the gap between informal and non-formal learning. In this study 30 Kenyan elite runners were equipped with a simple Android smartphone and free Internet for one year. The original research project focused on studying how a smartphone in the hands of impoverished Kenyans could assist and enhance informal learning. This project used log data, workshops and interviews to track the users’ progress. During the course of the study a huge desire for more formalized learning developed. Thus, a non-formal course on Human Rights was developed and made available for all Kenyans via any Internet connected device. In this way the intersection of these two projects provided an opportunity to satiate interests gained from unguided informal learning with structured non-formal learning. Key findings were that the smartphone empowered marginalized groups, augmented informal learning opportunities, and provided a means to bridge informal and non-formal learning to deliver educational opportunities to any device in the form of a non-formal MOOC. This research made a significant impact in the participants’ lives and the most common statement from the interviews was the statement “it helps us a lot”.

    Do-It-Yourself Learning in Kenya: Exploring mobile technologies for merging non-formal and informal learning2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The educational landscape is changing and a variety of technologies and techniques are blurring the lines between traditional and non-traditional learning. This change is substantial in low-income countries: individuals in developing countries have a great desire to educate themselves and improve their quality of life. Kenyans are adequately literate and accustomed to mobile technology despite being a largely impoverished, poorly educated populace. Kenya represents an optimal setting in which to research the use and feasibility of modern mobile and educational technologies. The broad aim of this dissertation is to explore how mobile devices can catalyze and enhance both informal and non-formal learning. In particular, this dissertation explores how technologies and concepts such as mobile web apps, Massive Open Online Courses (MOOCs), and learning incentives via a smartphone specifically affect informal and non-formal learning in Kenya. The primary research question is how can learning efforts that utilize mobile learning, MOOCs, and learning incentives combine non-formal and informal learning to develop and contribute to a do-it-yourself (DIY) approach to learning in Kenya? The primary method is action research. The first contribution of this dissertation is the finding that mobile web apps are currently better suited for data exchange than producing new content. The second contribution is the finding that a smartphone can enhance informal learning in a developing country with little or no scaffolding. The third contribution is the finding that non-formal learning efforts as a MOOC are shown to be a viable means of delivering non-formal learning in a developing country via a smartphone. The fourth contribution is the finding that the use of incentives such as digital badges provide a means by which to validate non-formal learning and contribute to a DIY attitude towards learning creation, where individuals can freely complement or replace a traditional curriculum.

    Native Apps Vs. Mobile Web Apps2013In: International Journal of Interactive Mobile Technologies (iJIM), ISSN 1865-7923, E-ISSN 1865-7923, Vol. 7, no 4, p. 27-32Article in journal (Refereed)
    Abstract [en]

    The extensive growth and expansion of smartphones and tablets and therewith the use of mobile web applications that utilize HTML5 and related technologies are frequently discussed and debated in media as possible replacements for native applications. The aim of this study was to explore the viability of replacing native applications with mobile web applications in a developing country setting. Two mobile web applications were developed. The first mobile web application tracked runs and the second mobile web application was a booking system for scheduling "slum runs". The subjects who tested these apps were elite, semi-professional Kenyan runners primarily from the Kibera slum area outside of Nairobi. After a 6-month test period the participants concluded and results indicated that the mobile web application for tracking runs performed poorly compared to native applications due to poor GPS performance, while the mobile web application for booking slum runs performed well. The conclusion from this study is that mobile web applications that require hardware interaction such as using the GPS, GPU, or camera are not yet viable alternatives for native applications. However, mobile applications that only require a native interface and content consumption are suitable substitutes for native applications.

    No University Credit, No Problem?: Exploring Recognition of Non-Formal Learning2014In: 2014 IEEE Frontiers in Education Conference Proceedings, IEEE Computer Society, 2014, 2420-2426, 2014, p. 2420-2426Conference paper (Refereed)
    Abstract [en]

    Massive Open Online Courses (MOOCs) are disrupting traditional, higher education and redefining how learning takes place online. These open courses typically offer some form of recognition, such as a certificate of completion and/or digital badge, to recognize, validate, and in some cases even accredit learning. A general problem with MOOCs is the uncertainty regarding the use and goals of recognition, validation, and accreditation (RVA), and participants' acceptance and perception of such techniques. This research effort addresses this problem by exploring course partici-pants' attitudes and levels of acceptance of non-formal learning recognition compared to traditional university credit in both devel-oped and developing countries. The actual study uses both certifi-cates of completion and digital badges to recognize and validate learning in an introductory, university level course in web pro-gramming using HTML5/CSS. The course is available to anyone, but was specifically marketed to participants from Sweden and Kenya. Empirical data was gathered using interviews and online surveys in the course. The preliminary results are that participants from developing countries value digital recognition to a greater extent than their counterparts in Europe. However, both Swedes and Kenyans see open courses with digital recognition as a com-plement to traditional learning to individually construct an educa-tion.

    Putting a MOOC for Human Rights in the Hands of Kenyans: The Haki Zangu Case for Non-Formal Learning2014In: Electronic Journal of Information Systems in Developing Countries, ISSN 1681-4835, E-ISSN 1681-4835, Vol. 65, no 3, p. 1-17Article in journal (Refereed)
    Abstract [en]

    The research goal of this project was to explore the use and effects of non-formal education and incentives in the context of a developing country. The practical aim of this project was to create, implement, and evaluate a platform about human rights that was available to any Kenyan for free in order to increase knowledge and engagement. Therefore, a non-formal massive open online course (MOOC) about human rights was designed and launched. The course was free and open to anyone in Kenya and offered both a digital badge and certificate from Stockholm University in Sweden upon completion. The course was called Haki Zangu (Kiswahili for "My Rights"), and it explored how using incentives such as a digital badge and certificate of completion affected learning outcomes. This course offered ubiquitous access based on principles of responsive web design and used audio recordings of the entire course content. The course is perpetual and still on-going, but after six months there were 160 participants who had enrolled, and ten participants had completed the course and received certificates and digital badges. The participants showed extensive enthusiasm and engagement for human rights issues, and they expressed desires to learn more and further spread knowledge about human rights. The current findings suggest that the availability of digital badges and certificates increased interest for participation and positively affected learning outcomes. Moreover, the use of a Massive Open Online Course (MOOC) format with incentives proved successful, combined with the contextualization and accessibility of the course content. Furthermore, the technical platform proved adequate for disseminating education for free in a developing country, and allowed for unencumbered access regardless of device. Lastly, a key challenge for future non-formal learning efforts in developing countries is the cost of Internet access.

    MOOCs for Professional Teacher Development2014In: Proceedings of Society for Information Technology & Teacher Education International Conference 2014 / [ed] M. Searson & M. Ochoa, Chesapeake, VA: AACE , 2014, p. 1580-1586Conference paper (Refereed)
    Abstract [en]

    A MOOC is a trending concept in education that is disrupting traditional methods oflearning consumption. The emergence and use of MOOCs for professional teacher development isstill uncommon, but on the verge of gaining a foothold. Research regarding MOOCs typicallyfocuses on impacts for higher education and lifelong learning. However, the specific intersection ofMOOCs and professional teacher development is poorly researched. This concept papercontemplates the benefits and drawbacks of using MOOCs for professional teacher developmentand calls for more practical studies and explorative research. This paper also speculates on the basicMOOC design criteria and principles needed to maximize engagement and course completion,which are currently common issues with general MOOCs. The conclusion is that MOOCs can be acost- and resource-effective means to deliver quality education in order to further professionalteacher development. However, possible risks are employers' reluctance to accept MOOCaccreditation as equivalent professional development and the lack of relevant MOOC courses forprofessional development.

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

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

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

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

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

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

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

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

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

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

    Microsoft WebMatrix: Enkelheten i dynamiska webbaserade system2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

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

    Abstract [en]

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

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

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

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

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

    Abstract [en]

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

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

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

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

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

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

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

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