Från föhn till feu! : Esrange och den norrländska rymdverksamhetens tillkomsthistoria från sekelskiftet 1900 till 1966 / From föhn to feu! : The history of Esrange and the Northern Swedish spaceactivity from the turn of the century 1900 until 1966

Backman, Fredrick January 2010 (has links)
<p>This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash. Finally, I examine the difficulty of talking about boundaries of various kinds, such as temporal, spatial and functional. The essay also provides a discussion on possible ways to continue research on this topic.</p>

From Vision to Transition : Exploring the Potential for Public Information Services to Facilitate Sustainable Urban Transport

Cano-Viktorsson, Carlos January 2014 (has links)
Background: Policy initiatives to promote sustainable travel through the use of Internet based public information systems have increased during the last decade. Stockholm, in being one of the first cities in Europe to implement an Internet based service for facilitating sustainable travel is believed to be a good candidate for an analysis of key issues for developing sustainable travel planning services to the public. Aim: This thesis investigates the past development of two Stockholm based public information systems and their services in order to draw lessons on how to better provide for a public information service geared towards facilitating  environmentally sustainable travel planning through information and communications technology. The overall goal of the thesis is to contribute to an understanding on how to better design and manage current and future attempts at facilitating sustainable travel planning services based on historical case studies. Approach: The thesis draws ideas from the concept of organizational responsiveness – an organization’s ability to listen, understand and respond to demands put to it by its internal and external stakeholders – in order to depict how well or not the two public information systems and their owners have adapted to established norms and values of their surroundings. Results: Overall, the findings from the historical case studies suggest that organizations attempting to provide sustainable travel planning to the public need to design and manage their systems in such a way that it responds to shifting demands on how to provide for information. Implementing and embedding new technologies involves complex processes of change both at the micro level – for users and practitioners of the service – and at the meso level for the involved public service organizations themselves. This condition requires a contextualist framework to analyze and understand organizational, contextual and cultural issues involved in the adoption of new technologies and procedures. Conclusions: The thesis concludes with a discussion on how the findings from the historical case studies may provide lessons for both current and future attempts at providing public information systems geared towards facilitating environmentally sustainable travel planning to the public. Historical examples and issues concerning collective intelligence and peer to peer based forms of designing, producing and supervising public information services identified throughout the study are looked upon and discussed in terms of their possible role in increasing the potential for public information services to facilitate sustainable urban transport. / <p>QC 20140319</p> / TRACS, Travel Planner for Sustainable Cities

Byzantine ports : Central Greece as a link between the Mediterranean and the Black Sea

Ginalis, Alkiviadis January 2014 (has links)
This thesis presents a first archaeological introduction to the study of Byzantine ports, harbours and other coastal installations in the region of Thessaly. Thessaly not only constitutes an ideal region to gain equal information for the Early- to the Late Byzantine periods, but also to compare independent regional and imperial central building activities. However, in particular Thessaly’s maritime connectivity has never been studied in detail before. As such, a first step into a terra incognita, the thesis is divided into two main sections: In order to conceptualize the study of harbour sites, the thesis first sets up a framework for the definition, understanding and interpretation of the physical features of harbours and their function and purpose. Taking into account influencing environmental conditions, such as natural, economic, social and political components, this helps to determine an accurate hierarchical model and to illustrate the interrelationship between different types and forms of harbour sites. Subsequently, comprehensive archaeological investigations around the island of Skiathos and other harbour sites in Thessaly, executed in 2012 and 2013, are set against this theoretical groundwork. In contrast to the common approach of regional studies, where a first general overview is followed by individual detailed case-studies, the opposite methodology is undertaken in order to achieve a systematic study of the Thessalian harbours and the complexity of their network system. Consequently, the collection of data starts from the analysis of a distinct area of a region and continues with the broader regional picture of primary ports, secondary harbours and staple markets. Functioning as an important junction of the Aegean shipping lanes and being involved in regional as well as supra-regional trade and port networks, focus is therefore primarily dedicated to the island of Skiathos. A joint survey project in cooperation with the Greek Ephorate for Underwater Antiquities (EEA), the 13th Greek Ephorate for Prehistoric and Classical Antiquities and the 7th Greek Ephorate for Byzantine Antiquities was initiated by the author in 2012. A number of sites, including harbour installations and other coastal infrastructures, have been detected, documented and subsequently verified by geophysical prospections, using a Sub-bottom profiler and Side-Scan Sonar, in 2013. These have allowed to draw a clear historical picture of architectural developments, port networks and changes in the socio-economic connectivity of the area. Followed by a close investigation of further harbour sites throughout the entire region of Thessaly during two field seasons between 2012 and 2013, the detailed picture gained from the Skiathos survey project is brought to a wider context. This comparison finally allows an overall picture of the history and architectural developments of harbour structures and associated coastal sites, as well as general conclusions concerning the hierarchy and port network in the region during the Early to Late Byzantine periods. This has allowed a comprehensive understanding of the growth, use and decline of various ports, harbours and staple markets within Thessaly and has important repercussions for our understanding of wider social and economic changes that were occurring during these periods, such as the rise of the church as a powerful economic institution or the increasing activities of private entrepreneurs. In this way the submerged maritime heritage of Thessaly has provided a rich new resource with which to understand the cultural dynamics of the region as it emerged from its peripheral location to comprising major ports within the Roman maritime network and to stand out of the heart of the commercial route ways to and from Constantinople, as well as being part of the emergent networks of the western maritime states at the end of the period, such as Venice.

Barocktakstolar i Sverige : en byggnadsteknisk och arkitektonisk dokumentation och analys / Baroque roof trusses in Sweden : a structural and architectural documentation and analysis

Ståhlkrantz, Simon, Möller, Ossian January 2019 (has links)
Arbetet behandlar takstolar från 1500-, 1600- och 1700-tal i barockstil. Syftet är att undersöka och analysera barocktakstolar samt bidra till en ökad kunskap inom området. Målet är att presentera byggnadsteknisk information om barocktakstolar i Sverige, att presentera en jämförelse mellan svenska barocktakstolar och att presentera en byggnadsteknisk dokumentation av barocktakstolen i Kalmar Rådhus. Undersökningens metoder bestod av litteraturstudie, dokumentstudie, en analysmodell för historiska takkonstruktioner, en byggnadsundersökning och uppmätning med laserskanning samt en framtagning av geometrimodell och beräkningsunderlag. Resultatet av arbetet visar en ökad kunskap om hur barocktakstolar i Sverige är konstruerade, att det finns karakteristiska drag mellan både svenska takkonstruktioner såväl som mellan svenska och europeiska. / This thesis treat roof trusses from the 16th, 17th and 18th centuries in Baroque style. The purpose is to investigate and analyze baroque roof trusses and to contribute to an increased knowledge in this field. The aim is to present a survey and building technical information of baroque roof trusses in Sweden, to present a comparison between Swedish baroque roof trusses and to present a building technical documentation of the baroque roof truss in the City Hall of Kalmar. The research methods consisted of a literature study, document study, an analysis model for historical roof constructions, a building survey and measurement with laser scanning as well as a development of a geometry model and calculation basis. The result of this work shows an increased knowledge of how baroque roof trusses in Sweden are designed, that there are characteristic features between both Swedish roof constructions as well as between Swedish and European.

Bränsle för den moderna nationen : Etanol och gengas i Sverige under mellankrigstiden och andra världskriget / Fuelling the Modern nation : Ethanol and Wood Gas as Alternative Fuels in Sweden during the Interwar Years and World War II

Ekerholm, Helena January 2012 (has links)
This thesis investigate Swedish policy-making concerning promotion of wood gas and ethanol distilled from fermented sulphite lye as domestic fuel alternatives in the Interwar years and World War II. With a departure point in the theories of social constructions of technology (SCOT), the sociology of expectations and Thomas P. Hughe’s socio-technical systems I analyse the measures that were undertaken in these efforts, the arguments put forward for and against the ethanol and wood gas projects and how the efforts turned out. I also investigate how the interpretations of ethanol and wood gas as fuel alternatives changed from the Interwar period on through World War II and what consequences this had for ethanol and wood gas policy immediately after World War II. Source material includes Parliament and Government records, cabinet meeting files, governmental commissions, authority archives, technical evaluations and handbooks and scientific medical publications. Ethanol and wood gas were promoted from a nationalist vantage point. The Interwar debate was imbued with visions of national techno-scientific prowess in a perceived ongoing global contest for technological and scientific advancement, of which achieving autarky, self-sufficiency on important raw materials and industrial products, was an ideal for some. Ethanol and wood gas were also promoted as means for creating a lucrative new market for the forestry industry, which also held a prominent position in nationalist visions of technology. Expectations of a new war also motivated the promotion of ethanol and wood gas as national fuels. Measures for promotion included tax exemptions, sales guarantees and legislation for mandatory ethanol purchase for all petrol importing companies and gasifier loan funds. Political conflicts mainly centred around the principles of free trade as opposed to protectionism, proper use of tax funds and whether the potentials of the fuel alternatives were rhetorically exaggerated. During World War II ethanol and wood gas in particular served as important petrol surrogates. The increased wood gas use led to negative interpretations of wood gas a fuel alternative due to its hazardous, dirty and time-consuming maintenance and the changed driving behaviour it required from its users compared to petrol or ethanol fuelled automobiles. Compared to wood gas, ethanol was appreciated for its socio-technical similarities to petrol, but production was after the war deemed difficult to maintain during wartime. Whereas wood gas remained an important stand-by surrogate during the cold war, Swedish politicians lost interest in ethanol of the kind that was promoted in the Interwar years. / Fuel of the Future?

Playing Second Fiddle: A history of technology and organisation in the Australian music economy (1901-1990)

Rooney, David Unknown Date (has links)
This thesis is a socio-economic history of the relationship between music technology and organisational practices in twentieth-century Australia. It argues that the history of technology in the Australian music economy is dependent not only upon the changing technical characteristics of musical instruments and electronic consumer goods but also upon government policy-making, management practices in music technology manufacturing firms and patterns of music technology consumption. The thesis examines economic statistics regarding the import, export and local production of music technology in Australia. The economic statistics have not previously been examined in relation to the history of music technology in Australia. The historical analysis is structured according to a four-part periodisation which includes the Electric Age (1901-1930), the Electronic Age (1930-1950), the Transistor Age (1950-1970) and the Information Age (1970-1990). This periodisation enables the analysis to continually be refocussed as the key technological and socio-economic dynamics change. With this perspective, the history of the relationship between technology and organisation in the Australian music economy has been demonstrated to be dependent on a number of key technological changes. The thesis examines changes including the shift from acoustic to electric recording; the development of transistor-based consumer electronics goods; and the advent of digital information technology. However, a number of key social determinants, particularly organisational modes, are examined including changes from protectionist to more deregulated trade policy; lack of business skills in areas such as marketing, manufacturing technique and industrial research and development; and the development of a sense of popular modernity which is expressed in the consumption of new, technically advanced and glamorous music technology. In addition to the new perspectives on the history of music technology provided by the analysis of empirical economic data, this thesis contributes to the historiography of technology. The analytical framework it proposes locates music technology within what is described as an assemblage of technologies: technologies of production, technologies of sign systems, technologies of power and technologies of the self. This approach makes clear the interdependence of technological and social factors, and the inadequacy of narrow technological determinist and social constructivist accounts. The notion of an assemblage of technologies is further embellished by drawing upon key elements of recent theories of systems analysis: the seamless web, evolution and chaos theory. Through this analytical framework and the socio-economic analysis of the relationship between music technology and organisational practices, the thesis demonstrates that the history of technology cannot be understood unless it is seen as part of a complex and interacting technical, social, economic and institutional system.
