  4. 7. Very high cycle fatigue of automotive steels : Testing and computation at 20 kHz

    Author : Mohamed Sadek; Jens Bergström; Nils Hallbäck; Ulrich Krupp; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very high cycle fatigue; ultrasonic fatigue testing; automotive steels; fatigue strength; stress intensity computation; crack growth; Materialteknik; Materials Engineering;

    Abstract : Mechanical fatigue failure occurs in components subjected to cyclic loading. A crack initiates at critical regions in the component and propagates during repeated loading. The expected fatigue life depends on the level, type and frequency of the loading. READ MORE

  5. 8. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

    Author : Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

    Abstract : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. READ MORE

  6. 9. A Non-Stationary perspective on the European and Swedish Business Cycle

    Author : Louise Holm; Högskolan i Skövde; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business cycles; business cycle dating; non-parametric smoothing; non-stationarity; recession prediction; interest rate spread; binary respons models; Business and economics; Ekonomi; Humanities and Social sciences; Humaniora-samhällsvetenskap; Business cycles; business cycle dating; non-parametric smoothing; non-stationarity; recession prediction; interest rate spread; binary response models.;

    Abstract : Business cycles, the ups and downs observed somewhat simultaneously in numerous macroeconomic variables in an economy and often measured using real GDP, are important and, despite much economic research, still incom- pletely understood. Dating the business cycle has always been of interest in macroeconomic research. READ MORE

  7. 10. Taking stock of large-scale lithium-ion battery production using life cycle assessment

    Author : Mudit Chordia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brine; Spodumene; Lithium-ion battery; Lithium; Life cycle assessment; Giga-factory; Upscaling;

    Abstract : Battery electric vehicles are being increasingly favored as an alternative to internal combustion engine vehicles (ICEVs). This is mainly due to their lower environmental impact when compared to ICEVs over the vehicle’s lifetime. READ MORE
