  2. 16. Environmental Impact Assessment using Production Flow Simulation

    Author : Jon Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Event Simulation; Life cycle assessment; Environmental impact assessment;

    Abstract : A higher-level perspective for production engineers and enables detailed assessment of dynamic manufacturing systems environmental impact at a system level. By using simulation, the simulation engineer enables to understand how minor adjustments affect the system. READ MORE

  4. 17. Fatigue improvement of steel bridges with high-frequency mechanical impact treatment

    Author : Poja Shams Hakimi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HFMI; thickness effect; bridge; steel; variable amplitude; fatigue;

    Abstract : This thesis investigates the performance of fatigue-improved welds with high-frequency mechanical impact (HFMI) for application on new bridges. Fatigue strength improvement with HFMI can enable lightweight design of bridges and allow the utilisation of the benefits of high-strength steels. READ MORE

  5. 18. Simplified Life Cycle Assessment Approaches and Potential Impact Shifts

    Author : Katja Tasala Gradin; Sofia Ritzén; Anna Hedlund-Åström; Matthias Finkbeiner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA simplification approach; impact shift; reduction measures; road transport; streamlining; screening; Machine Design; Maskinkonstruktion;

    Abstract : Road transport contributes to approximately one quarter of all EU greenhouse gas emissions and is the leading cause of air pollution in cities. There are significant measures aimed at the reduction of use phase environmental impacts; in the EU, these strategies focus on the decarbonisation of road transport, such as through the prioritization of low- and zero-emission vehicles.

  6. 19. Multinationals, employment and wages : microeconomic evidence from Swedish manufacturing

    Author : Roger Bandick; Pär Hansson; Holger Görg; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Foreign acquisitions; labor demand; matching; difference-in difference; multinational enterprises and survival analysis.; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Abstract : The aim of this thesis, consisting of four essays, is to study the effects of multinationals and inward FDI on employment and wage formation in Swedish manufacturing during the 1990s. Paper [1] (co-authored with Patrik Karpaty) investigates the employment effects of foreign acquisitions in acquired firms in Swedish manufacturing during the 1990s. READ MORE

  7. 20. In-situ analysis of process characteristics in Directed Energy Deposition
