This thesis focuses on the evolution of the Internet system. It examines the dynamics of competing and collaborating technologies in the invention and development of computer networking technologies in general. In particular, it examines the negotiations among social groups with different economic and political interests in designing the Internet system. This system has been shaped by competition and collaboration between the US and other countries (other regions) reflecting their different institutional arrangements in the telecommunications sector and the dynamics of uneven power relationships. Population dynamics, i.e. similarities and differences in the growth and pervasiveness of the Internet system between regions and countries, are also examined to uncover how the co-evolution between technological system and social, cultural, and economic systems countries influenced by global and local interplay. This thesis combines techno-economic and socio-technological approaches in technology studies to address the 'localisation' of a technological system, how a system adapted to or was influenced by the local context of its application. This research focuses on empirical evidence about the evolution of the Internet system, recognizing that the Internet system is one instance of a large technological system. In addition, the political economy perspective provides a foundation for an integrated analysis of the local situation and the wider power structure which illustrates the economic and political interests that are embedded in the design and development of the Internet system. The main research questions are how have political and economic interests shaped the evolution of the Internet system and why does the outcome of the Internet system's development vary across countries? The Internet system emerged from one of the early experimental computer networks in the US, the UK and France during the development of packet switching technology and it involved mainly computer scientists. The development of packet switching technologies has been shaped by battles for control between network operators and computer manufacturers as a consequence of technological convergence; and between telecommunication operators and advanced users (e.g. computer engineers and scientists in the case of the Internet system) in the process of institutional change in telecommunications sector. The analysis shows how these battles were guided by different interests and strategies between, notably, the US and European countries. The analysis of the population dynamics of Internet system development confirms its uneven development between countries following regional, economic and cultural routes. It also confirms that the international spread of the Internet network is influenced by different choices of ICTs and non-linear relationships between competing technologies. The sources of uneven development of the Internet system are founded in the global expansion of the Internet system. These sources are shown to include: asymmetric development of research networks between regions and countries, the effects of the different economic and political interests of the US (and European countries) in connecting the Internet to other countries and regions, the US-centered network design and the international financial settlement regime for the Internet in addition to the existing technological and economic gaps and cultural differences between countries that influence the localisation of the Internet system. The empirical findings that emerge from the econometric modelling demonstrate that knowledge production and distribution capabilities, global integration efforts, economic strength and equality of income distribution, size of social system, telecommunication policies, science and technology policies, prices for access and using of the Internet, all influence the localisation of the Internet system. The thesis contests many accounts of the diffusion of the Internet that are based on 'technological inevitability' and the 'universality' of the technical methods chosen.

The energy sector is one of the largest contributors to carbon emissions, thus it must change to renewable energy sources. However, common green energy sources show weaknesses in stability. To overcome this, offshore wind parks are a promising approach, because they provide a more stable energy supply. Nevertheless, it is difficult to build them, as the maritime environment poses many challenges. To vanquish this endeavor, extensive planning is required. This thesis has analyzed the challenges in planning for the two German offshore wind parks Baltic Eagle and He Dreiht through the theoretical lens of the large technical systems approach. The method of thematic analysis has revealed four major challenges in the planning process, that are environmental, technical, economic, and societal challenges. Often, these challenges relate to each other, for example when technical innovations are used to mitigate environmental challenges. Even though the challenges are dependent on the location of the project, the analysis discovered distinct patterns that are generally occurring. Lastly, this thesis contributes to a better understanding of planning for offshore wind parks as part of the energy transition.

Due to the increasing threat of global warming, today’s grid system faces large changes and challenges as more renewable sources are being implemented in the grid. In order to handle these changes and secure future distribution, new technologies and components are necessary. This study investigates the innovation – IT/OT integration and its rate of adoption among potential adopters – Distribution System Operators. Based upon 8 expert interviews, 19 interviews with Swedish DSOs and literature, the study has concluded the following: - Increased micro production in the Swedish electricity grid system is the main drivers for IT/OT integration. IT Security and Swedish Energy Market Inspectorates current pricing model are two of the main inhibitors for IT/OT integration. - Key factors, such as perceived attributes of the innovation and business transformation speed are of high importance when analyzing rate of adoption. - Medium-sized DSOs with high ambition are likely to adopt before other customer segments. Thus, they are potential target customers for suppliers, such as Ericsson. The thesis contributes to literature by providing research of a technical innovation within a complex market. Future research of interest is to apply similar methodology for predicting rate of adoption of IT/OT integration in other nations, since drivers and regulations might differ. / Det ökade hotet från klimatförändringar har medfört att dagens elnätssystem står inför stora förändringar och utmaningar då allt fler förnyelsebara källor implementeras i elnätet. För att hantera denna förändring och säkra framtidens eldistribution krävs att ny teknik och nya komponenter implementeras i elnätet. Denna rapport undersöker innovationen - IT/OT integration och hur denna sprids bland potentiella kunder – elnätsdistributörer. Baserat på 8 expertintervjuer, 19 intervjuer med svenska elnätsdistributörer och litteratur har studien kommit fram till följande slutsatser: - Ökad mikroproduktion i det svenska elnätet är den främsta drivaren för IT/OT integration. IT säkerhet och Energimarknadsinspektionens nuvarande regleringsmodell är idag två av de främsta barriärerna för IT/OT integration. - Huvudfaktorer, så som förväntade uppfattningen av innovationen och företags omvandlingshastighet är av stor betydelse för att uppskatta spridningshastigheten av innovationen. - Mellanstora DSOer med höga ambitioner kommer troligast ta till sig tekniken tidigare än andra kundsegment och bör därför vara potentiell målgrupp för leverantörer, så som Ericsson. Rapporten bidrar till forskningen genom att en teknisk innovation analyserats i en komplex marknad. Vidare undersökningar som kan genomföras är att applicera motsvarande metodik för estimera spridningen av IT/OT integration i andra länder, då drivare och regleringar där kan skilja sig från Sverige.

Air traffic services (ATS) play an important role for flight safety. Remote air traffic services (RATS) represent a novel, more digitalized, ATS solution. In some aspects, RATS can be argued to outperform conventional ATS. However, as it entails various sociotechnical obstacles, making RATS the dominant solution for ATS is challenging. An inadequate awareness of such sociotechnical obstacles potentially impedes the competitiveness of RATS in general and the RATS providers in particular. This study intends to - from a sociotechnical perspective - identify main obstacles as faced by RATS when aspiring to become the dominant solution for ATS. In order to identify such obstacles, an abductive case study has been conducted. Empirical data was primarily gathered by semi-structured interviews with 10 key stakeholders involved, directly or indirectly, with RATS. The study is delimited to principally gather empirics from Sweden and the United Kingdom. Theoretical concepts of Large Technical Systems (LTS) and the Multilevel Perspective (MLP) are employed to understand and analyze the empirical data. The identified obstacles faced by RATS are mapped into the different levels of the MLP. Obstacles have been identified in all levels of the MLP. The most prominent obstacles seem to lay in social aspects of change processes, a proposition-perception gap, and connectivity infrastructure dependency. / Flygtrafiktjänster (ATS) spelar en viktig roll för flygsäkerhet. Fjärrstyrda flygtrafiktjänster (RATS) representerar en ny, i högre grad digitaliserad, lösning för ATS. I vissa avseenden kan RATS anses prestera bättre än konventionellt utförda flygtrafiktjänster. Vägen mot ett tillstånd där RATS är den dominerande lösningen för RATS är dock kantad av olika sociotekniska utmaningar. En otillräcklig medvetenhet om dessa utmaningar kan potentiellt minska konkurrenskraften för RATS i allmänhet och för utvecklare av RATS i synnerhet. Denna studie syftar till att, från ett sociotekniskt perspektiv, identifiera utmaningar som RATS står inför i, en situation där RATS ämnar ta steg mot att bli den dominerande lösningen för ATS. För att identifiera sådana utmaningar har en abduktiv fallstudie utförts. Empirisk data samlades huvudsakligen in genom semi-strukturerade intervjuer med 10 intressenter, direkt eller indirekt involverade, i RATS. Studien är avgränsad till att huvudsakligen samla in empirisk data från Sverige och Storbritannien. Teoretiska ramverk och begrepp beträffande Large Technical Systems (LTS) och Multilevel Perspective (MLP) används för att förstå och analysera empirisk data. De identifierade utmaningarna kopplas till de olika nivåerna i MLP. Utmaningar har identifierats i alla nivåer av MLP, och de mest framstående utmaningarna tycks ligga i sociala aspekter av förändringsprocesser, ett gap mellan proposition och perception, samt ett beroende av uppkopplingsinfrastruktur.
