  2. 1. New innovative methods for non-intrusive optical diagnostics of high-voltage insulator materials

    Author : Magnus Bengtsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atom- och molekylärfysik; Atomic and molecular physics; akustik; optik; optics; acoustics; Electromagnetism; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; fluorescence; optical diagnostics; high-voltage insulation; remote sensing; polymeric insulators; lidar; biological contamination; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Energy research; Energiforskning; Elektromagnetism;

    Abstract : The purpose of this PhD thesis work has been to develop optical techniques that can help utility engineers for assessing the state of insulators in service and in a laboratory. The possibilities to use remote laser induced fluorescence for detection and imaging of biological growth such as algae and fungi have been investigated. READ MORE

  4. 2. On the Possibilities of Detecting Surface Charges with Second Harmonic Generation and Optical Diagnostics of Polymeric Insulators

    Author : Magnus Bengtsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Optical second-harmonic generation can be a sensitive probe of atoms and molecules at a surface or interface. For this reason, the method was chosen to study surface charges. READ MORE

  5. 3. Environmental Valuation and Life Cycle Assessment

    Author : Magnus Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : .... READ MORE

  6. 4. Facts and Interpretations in Environmental Assessments of Products

    Author : Magnus Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater systems; weighting; learning; decision making; legitimacy; environmental trade-offs; sewage sludge; life cycle assessment LCA ; controversy; environmental evaluation;

    Abstract : Contemporary environmental discourse increasingly emphasises environmental impacts associated with products. In response to this attention, methods for assessing the impacts of products over their life cycles, life cycle assessment (LCA), have been devised. READ MORE

  7. 5. Quality-Driven Production of Aggregates in Crushing Plants

    Author : Magnus Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; breakage; crushing; simulation; modelling; Keywords: aggregate quality; particle shape;

    Abstract : Aggregate quality is of great importance, and in this context it is essential to understand how various process parameters influence the product quality characteristics. Thus, there is a need for aggregate producers to improve their process knowledge. READ MORE
