  1. 1. Ages of liberty : social upheaval, history writing, and the new public sphere in Sweden, 1740-1792

    Författare :Peter Hallberg; Peter Burke; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; historiography; civil society; public sphere; public opinion; diffusion; collective; Political science; Statsvetenskap; Political Science; statsvetenskap;

    Sammanfattning : This dissertation investigates how different social groups used history as a political instrument in Sweden during the second half of the eighteenth century (1740-1792). More specifically, it analyzes how representations of the past were used to influence behavior, legitimize claims to power, mould opinion and forge collective identities. LÄS MER

  3. 2. Low-Cost Demonstrators : Enhancing Product Development with the Use of Physical Representations

    Författare :Peter Hallberg; Johan Ölvander; Petter Krus; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Ever since the early nineties and the advent of affordable and comprehensive 3D-CAD systems, companies have striven to take advantage of cost-effective Virtual Prototyping, gradually moving away from activities involving physical representations of the evolving product. There are, however, aspects of the product development process that are less suitable for virtual exploration. LÄS MER

  4. 3. Mixed Oxide Oxygen Carriers for Chemical-Looping Combustion

    Författare :Peter Hallberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-Looping Combustion CLC ; ilmenite; calcium manganite; oxygen carrier; CO2 capture; Chemical-Looping with oxygen uncoupling;

    Sammanfattning : Chemical-Looping Combustion is a promising method for combustion with inherent carbon dioxide capture. Oxygen is provided to the fuel with a solid oxygen carrier. The oxygen carrier is circulated between the reactor for fuel oxidation and another reactor where it is reoxidized with air. A good performing oxygen carrier is vital for this process. LÄS MER

  5. 4. On Knowledge Creation and Learning at the Intersection of Product Development and Engineering Education

    Författare :Peter Hallberg; Johan Ölvander; Jonas Detterfelt; Kerstin Johansen; Johan Malmqvist; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Product Development; Engineering Education; Learning Analytics;

    Sammanfattning : Today’s demands on higher engineering education given the rapid transformation of society are, to say the least, multifaceted. Rapidly increased complexity of technology as well as adaptation to sustainability requirements are causing major transformations and mergers of whole domains of technology that strongly impact current and future engineering workforces within these domains, in particular, the need for new competencies.
