  2. 6. Image-based quantitative infrared analysis and microparticle characterisation for pulp and paper applications

    Author : Kari Hyll; Lars Mattsson; Hannes Vomhoff; Samuel Schabel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metrology; stock; papermaking; refining; fibrillation; fines; filler; morphology; classification; flow microscopy; fibre analyser; flow cytometry; laser diffraction; dynamic image analysis; process variation; thermography; emittance; emissivity; infrared; MWIR; LWIR; goniometer; Production Engineering; Industriell produktion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. READ MORE

  4. 7. Design of Cellulose-Based Electrically Conductive Composites: Fundamentals, Modifications, and Scale-up

    Author : Karishma Jain; Lars Wågberg; Per A. Larsson; Davide Beneventi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; PEDOT:PSS; chemically-modified cellulose fibers; fundamental interactions; bioelectronics; energy storage; conductive paper production; large-scale production; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Modern demand for consumer electronics is fueling the generation of 'E-waste.' Furthermore, theraw materials and manufacturing methods used in the fabrication of electronics are not sustainable. READ MORE

  5. 8. Optimization product parts in high pressure die casting process

    Author : Mohammad Sadeghi; Rebei Bel-fdhila; Dan Loyd; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industriell ekonomi och organisation; Industrial Economics and Organisations;

    Abstract : This thesis describes optimization of die temperature in high pressure die-casting (HPDC) of A380 alloy by experimental observation and numerical simulation with the use of statistical tools. The goal of this research is to determine the optimum die temperature to minimize incidence of these defects and thus maximize production of parts without defects. READ MORE

  6. 9. Supply and value chain analyses of warqe food products in relation to post-harvest losses

    Author : Ashenafi Chaka Tuffa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Post-harvest losses are a global problem and are of critical importance in food-insecure countries such as Ethiopia. Losses of root and tuber crops are known to be high in developing countries, where many of the population are dependent on these crops. Warqe (Ensete ventricosum (Welw.) Cheesman) is a staple crop in Ethiopia. READ MORE

  7. 10. On Gas Turbine Conceptual Design

    Author : Konstantinos Kyprianidis; Vishal Sethi; Johan van der Spuy; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The thesis begins with a review of the evolution of the industry's vision for the aero-engine design of the future. Appropriate research questions are set that can influence how this vision may further evolve in the years to come. READ MORE
