  4. 2. Microscopy of high temperature oxidation of iron and some stainless steels

    Author : Torbjörn Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water vapour; sulphur dioxide; FIB; X20; stainless steel; 353MA; EDX; KCl; FIB SEM; SEM; microstructure; TEM; iron; High-temperature oxidation; in-situ ESEM;

    Abstract : This thesis concerns the high temperature oxidation of iron and some stainless steels. The oxide scales, as well as the subjacent metal, were investigated using a range of electron and ion microscopy techniques, including SEM, TEM, EDX and FIB. The aim was to link the microstructural observations to the oxidation mechanisms of the materials. READ MORE

  5. 3. Surface Status Classification, Utilizing Image Sensor Technology and Computer Models

    Author : Patrik Jonsson; Hans-Erik Nilsson; Benny Thörnberg; Jörgen Bogren; Torbjörn Eltoft; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road condition; NIR; infrared; remote sensing; signal processing; classifiers;

    Abstract : There is a great need to develop systems that can continuously provide correct information about road surface status depending on the prevailing weather conditions. This will minimize accidents and optimize transportation. READ MORE

  6. 4. An evaluation of regional sustainability by analysing energy and carbon flows – A study of Jämtland, Sweden

    Author : Torbjörn Skytt; Bengt-Gunnar Jonsson; Fredrik Ståhl; Magdalena Svanström; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Regional sustainability; Energy flows; Exergy; Carbon GHG fluxes; Sustainability indicators; carbon dioxide emissions; methane emissions; nature emissions;

    Abstract : Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. READ MORE

  7. 5. Fossil Free or Not - That is the Question

    Author : Torbjörn Skytt; Bengt-Gunnar Jonsson; Monica Odlare; Markku Rummukainen; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fossil free; Carbon balance; Carbon flow; Energy flow; Climate mitigation; Governing climate change; Forest carbon;

    Abstract : This is an evaluation of Jämtland County’s ability to achieve its climate targets to reduce greenhouse gas (GHG) emissions with 10% annually, and to become fossil fuel free 2030. There is a risk that the target to become fossil fuel-free, relying primarily on outtake of forest biomass, contradicts with the target in the UN Paris Agreement to keep the global temperature increase below 1.
