    How does the complexity of a road network affect optimal facility locations?2015Report (Other academic)
    Abstract [en]

    The road network is a necessary component in transportation. It facilitiesspatial movements of people and goods, and it also influences the optimal locations of facilities that usually serve as destinations of the movements. To fulfill the transportation needs and to adapt to the facility development, the road network is often organized hierarchically and asymmetrically with various road levels and spatial structures. The complexity of the road network increases along with the increase of road levels and spatial structures. However, location models locate facilities on a given road network, usually the most complex one, and the influence from the complexity of road network in finding optimal locations is not well-studied. This paper aims to investigate how the complexity of a road network affects the optimal facility locations by applying the widely-applied p-median model. The main result indicates that an increase in road network complexity, up to a certain level, can obviously improve the solution, and the complexity beyond that level does not always lead to better solutions. Furthermore, the result is not sensitive to the choice of algorithms. In a specific case study, a detailed sensitivity analysis of algorithm and facility number further provides insight into computation complexity and location problems from intra-urban to inter-urban.

    Filmklipparens arbetsprocess i Hollywood och Europa: Undersökning av möjliga skillnader och likheter i filmklipparens arbetsprocess i Hollywood och Europa2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Arbetsprocessen har förändrats under filmhistoriens gång, delvis på grund av teknologiska framsteg, som till exempel bytet till digitala filmklippningsverktyg. Hur filmklippningsprocessen ser ut, skiljer sig mellan filmklippare, men kan man även finna skillnader mellan olika regioner?

    Den här uppsatsen undersöker ifall det finns några likheter och skillnader mellan arbetsprocessen för filmklippning i Europa och Hollywood. Undersökningen genomförs genom en kvalitativ analys, där material samlas in från diverse påståenden från filmklippare i litteratur, samt från kvalitativa intervjuer som genomförs med filmklipparna Martin Hunter och Michal Leszczylowski.

    Resultatet pekar på att det finns både likheter och skillnader mellan de två regionerna. De båda regionernas arbetsprocess har påverkats av bytet till digital filmklippning. Deras arbetsuppgifter liknar på många sätt varandra, med det skiljer sig hur dessa arbetsuppgifter utförs. I Hollywood kan det ofta skådas mer resurser tillgängliga för filmklipparen, men samtidigt också mer inflytande från producenter och filmstudior på deras arbete. Däremot har filmklipparen i Europa ett starkare samarbete med regissören, och enligt dem är deras huvudsakliga uppgift att arbeta fram regissörens vision av filmen.

    Game music: from composer to consumer2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    By conducting an experiment involving interviews with successful video game music composers

    about the emotions they wish to convey to the players with their music, and a survey questioning

    consumers about what emotions they actually experienced while listening to these musical pieces,

    this bachelor's thesis tries to provide a deeper understanding for music in games and the impact it

    has on the player and whether or not the three composers that has been interviewed has succeeded

    with conveying the emotions they wished to convey to their consumers. The results showed that

    each composer that has participated has been able to convey the music's intended emotions to their

    consumers more or less. Almost none of the musical pieces used stood out as wrongly perceived by

    the survey participants. The preconceptions we have about emotions in music, both generally and in

    video games, has become so deeply rooted that by only listening to a musical piece one can

    determine its emotive state and character.

    Etablerade konventioner vid användning av synthar: Tre producenter av elektronisk musik och deras inställning till klaviatur och förinställda ljud hos synthar.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Synthen är ett instrument vars ljud inte behöver begränsas av dess fysiska form och utseende i

    samma utsträckning som instrumenten före dess tid. Inte heller är den begränsad till ett

    signifikant ljud utan har möjligheten att producera en enorm variation av både imitativa som

    unika ljud. Men med tidens gång har vi etablerat och fastställt vissa etablerade konventioner

    vid användningen av synthen, underliggande koncepten som tidigare paradigm har skapat

    inom vår förhållningsätt till den.

    Syftet med undersökningen är att belysa två etablerade konventioner i synthens

    användargränssnitt och ljuddesignsfunktion, nämligen klaviatur och förinställda ljud. Detta

    för att sedan med hjälp av tre djupintervjuer forma en bild av hur några av dagens producenter

    av elektronisk musik tycker, tänker och använder sig av dessa funktioner. För att ge en

    referenspunkt till konventionerna som behandlas i intervjuerna har litteratur om synen samt

    utvecklingen av synthen studerats och satts i kontext med paradigmbegreppet.

    Resultatet av undersökningen antyder på att konventionerna inte används i dess ursprungliga

    mening i fallet med de tre informanterna. Dock så letar sig konventionerna in i många av de

    synthar som informanterna använder sig av. Musikstil påverkar även hur producenterna

    använder sig av de etablerade konventionerna, Detsamma gäller även i viss mån användandet

    av synthar i live sammanhang.

    Användbarhetstester i ERP-system: för ökad användbarhet efter konfigurering2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Business system or ERP (Enterprise Resource Planning) is moving toward developing into so -called global systems. The systems’ functionality should be adapted to the businesses’ and users’ needs. Thus the notion of usability becomes essential.

    Usability of ERP systems is a limited research area. At the same time, it is widely known that ERP-systems’ user interface is a complex issue, which affects usability in a negative way for the users. To investigate the usefulness of usability testing methods can be applied. This was also something that was implemented in the current study when SSAB EMEA wanted to test the user interface usability of the new ERP system that is planned to be implemented soon.

    The study's research questions were: How experienced ERP system users its usefulness? and, How can usability tests be helpful in the configuration of the user interface of an ERP system?. The purpose of this study was to create a deeper understanding of how usability testing can be helpful before configuring the user interface of an ERP system, so that users perceive it useful. A case study was conducted through group interviews and usability tests, where ten users participated.

    The results were analyzed and presented using five usability criteria for ERP systems. Firstly, Navigation shows that users felt the system navigator with folder structure as difficult while shortcuts in the form of icons and links were seen as something positive. Learnability shows that users experienced in the previous system IFS7 found it easy to learn the new system IFS8. Users who lacked previous experience, however, experienced problems and frustration when the system required no obvious commands to perform tasks. Following guidance, also these users experienced that the system was easy to learn. Presentation shows that all the users were positive about the possibility of adapting the user interface along their own work role and how their selves operate. The system's adaptation to the users and the business, Customization, shows that the users were positive towards the system shortcuts in the form of icons and links to activities. Additionally, the users were positive about the prefilled data which were based on the logged in user. Finally, the Task support shows that users requested help functions that already existed in the system, but that was not noticed by the users.

    The implications of the study come to create a deeper understanding of usability in IFS8. This helps to SSAB EMEA, can configure the user interface for enhanced usability. In addition, the study indicates that users are in need of an organized training in the system before it is deployed, in order to enable them to conduct their activities in a satisfactory manner.

    Resan mot Sydneys operahus alternativt chips, öl och spela rock: En kvalitativ studie om hur aspirerande artister beskriver sina drömmar med musiken2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Som aspirerande artist är det ett nålsöga att infria sina drömmar med musiken, många försöker

    men desto färre lyckas. Syftet med denna kvalitativa studie är att undersöka hur aspirerande

    artister beskriver sina drömmar med musiken. Studien ämnar dessutom besvara huruvida

    genretillhörighet upplevs korrelera med hur drömmarna beskrivs. För undersökningen har åtta

    aspirerande artister intervjuats där hälften är pop-artister medan andra halvan består av

    alternativa artister (punk och indie). Forskningsresultatet visar att pop-artisterna i regel

    beskriver större drömmar än de alternativa artisterna. Samtliga respondenter delade dock

    drömmen om att kunna livnära sig på musiken. Däremot tenderade pop-artisterna att drömma

    om större summor pengar än de alternativa artisterna som istället nöjde sig med att kunna

    försörja sig på sitt artisteri. Mellan genrerna delades även viljan att ta musikkarriären så långt

    som möjligt. Resultatet visar dock att det mellan respondenterna råder delade meningar

    huruvida genretillhörighet korrelerar med hur de beskriver sina drömmar. Hälfterna av popoch

    de alternativa artisterna upplevde att genretillhörighet haft en påverkan medan övriga

    respondenter var osäkra eller inte reflekterat över genretillhörighetens påverkan.

    Idé och innovation2012Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Present thesis is to deepen the current knowledge about the concept anddevelopment of ideas of innovators and the potential small businesses in ruralareas has to adopt innovation and new technology. The thesis is limited tostudying the process itself and the progression from concept and development ofideas for invention and innovation to market and customer.The research questions include: What motivates an inventor to innovate? Howto practice innovation in small companies? How are innovators approach toproblem solving? What opportunities exist for small businesses in rural areas toadopt innovations and new technologies?The thesis also discusses on the one hand innovators approaches to motivationand attitude and on the other hand, how ideas are selected and then developed inthe process and progression in the author via the invention to market andcustomer innovation. In the present thesis has been both quantitative andqualitative approach, based on behavioural research.Important conclusions from this thesis is: that the innovation process should bedeleted and recorded by the (basic) idea and author; innovator must remain in thedevelopment of ideas with complementary and alternative ideas, innovationprocess, the progression from idea to innovation should be based on a ʺbottom upʺperspective, where the patent law “previous user rights” supports innovatorsinvolvement in the process and progression

    Inventor motivations to go from idea to innovation?2011In: Ergonomis for all: Celebrating PPCOE's 20 Years of Excellence / [ed] Lin, Dyi-Yih Michael, Leiden: CRC Press , 2011, p. 461-464Conference paper (Refereed)
    Abstract [en]

    The objective of present paper is to describe the motivations that underlie the choices made by inventors in the development of their technologies. These classifications can help managers of innovation programs direct sparse resources to inventors with the greatest probability of commercial success. The categorisation motivation to go from idea to innovation and commercialisation of new technologies is presented for inventors for the small business in rural area of Sweden. The main results showed least eight different inventor motivations.
