    IBMs stordators framtid i en molnbaserad IT värld: Kommer IBMs stordator att överleva ytterligare ettparadigmskifte eller har den spelat ut sin roll?2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    IT analytiker har många gånger gett IBMs stordator en dödsdom. Redan 1991 skrev denerkände kritikern Stewart Alsop, dåvarande chefredaktör på InfoWorld att den sista stordatornskulle tas ur bruk den 15 mars 1996. Det visade sig att detta uttalande var felaktigt, vilketStewart Alsop även erkände i InfoWorld bara dagar innan hans förutsägelse skulle ha infallit.När vi nu går in i ytterligare ett paradigmskifte i och med att många tjänster går över tillmolnet, ställer jag i denna uppsats frågan om IBMs stordator har en framtid i en molnbaseradIT värld, och hur den i så fall ser ut.

    Syftet är att genom litteraturstudier och intervjuer undersöka om IBMs stordator kan överlevaytterligare en genomomgripande teknikrevolution eller om den har spelat ut sin roll.Undersökningen mynnar ut i slutsatserna att IBMs stordator har en stark position i dagsläget,framförallt inom bank och finanssektorn d.v.s. inom branscher med speciellt höga kravbeträffande tillgänglighet, skalbarhet, och säkerhet. Sannolikt har stordatorn en viktig roll attspela även för framtidens satsningar i molnet. IBM erbjuder redan idag molnlösningar sominkluderar mainframes, och det framgick även i de intervjuer som gjordes på IBM, att de seren ljus framtid för IBMs stordatorer. De menar att IBM inte bara följer med, utan även är medoch leder utvecklingen inom molntjänster, och att det är främst för de öppna standarderna somLinux och Unix som IBM kommer att ha den ljusaste framtiden. Det faktum att IBM varje årinvesterar miljardbelopp i utvecklingen av sina stordatorer talar också sitt tydliga språk, d.v.s.att IBM fullt ut verkar tro på att stordatorn har en viktig roll att spela i den molnbaserade ITvärldsom just nu växer fram

    Business model innovations for overcoming barriers in the base-of-the-pyramid market2017In: Industry and Innovation, ISSN 1366-2716, E-ISSN 1469-8390, Vol. 24, no 5, p. 543-568Article in journal (Refereed)
    Abstract [en]

    Many barriers must be overcome when entering the base-of-the-pyramid (BoP) market. Firms facing these barriers need to innovate new business models and reinvent existing ones to suit the BoP context. While previous literature has focused on the innovations of particular components of business models in BoP markets, we investigate the reconfigurations in the business model components that underpin the successful business model innovations. This study is based on multiple case studies in the water sector that we carried out in several different countries. Our findings suggest five business model innovations: (a) design, (b) renewal, (c) expansion, (d) diversification and (e) replication. Each business model innovation is a specific response to the barriers met in the BoP market and requires consistent configuration between its various components (i.e. value proposition, value creation and profit equation). These findings add, in two important aspects, to the academic realm of the business model domain: by contributing to the debate of business models in BoP markets and by advancing the configurational view of business models.

    Utveckling av ingångsinterface till tändstyrenheter för naturgas- och biogasmotorer2013Independent thesis Basic level (professional degree), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    SEM AB develops and manufactures ignition control units for internal combustion engines, including natural gas and biogas engines. The ignition control units control the ignition process, when they receive a trigger signal from the engine control unit (ECU). Because these units are used with several different ECUs, they must be adapted for different signaltypes and number of cylinders. Adaptations of both the software and the hardware must be done and this requires time and resources for the developers at SEM.

    The purpose of this work is to develop an input interface for the ignition control units that allow them to be adapted more easily. Also, to minimize the number of components in the ignition control units, functions that are realized with discrete components shall, if possible, be integrated in the input interface.

    A suitable programmable circuit, for the application, has been selected. The selected circuit was a MAX V CPLD (Complex Programmable Logic Device) from Altera. The functions of the input interface have been created, in the form of Verilog programming code. Finally, simulations of the program have been made and its function has been verified using a development board.
