  2. 21. Exploring N-alicyclic quaternary ammonium functional polymers as hydroxide exchange membranes

    Author : Joel Olsson; Centrum för analys och syntes; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrolyte membrane; Anion exchange membranes; Anion exchange membrane fuel cells; Structure-property relationship; Quaternary ammonium cations; Alkaline stability; Synthesis; Characterization;

    Abstract : As the global power generation is shifted toward renewable and intermittent sources, the importance of fuel cells and other energy storage and conversion devices is continually increasing. However, many of these technologies are still under development and further research is necessary before they can be implemented. READ MORE

  4. 22. Virtual environments as a tool for people with acquired brain injury

    Author : Mattias Wallergård; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : People with acquired brain injury (ABI) often have problems leading an independent life due to impaired cognitive abilities. One way to address this is to let the patients practise activities of daily living as part of their rehabilitation process. However, some everyday activities can be difficult, inconvenient or risky to practise. READ MORE

  5. 23. Development of fine-mesh methodologies for coupled calculations in Light Water Reactors

    Author : Klas Jareteg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Coupled neutronics thermal-hydraulics; nuclear reactor multiphysics; multiphase flow;

    Abstract : This thesis presents fine-mesh multiphysics methodologies and algorithms for numerical predictions of the behavior of Light Water Reactor (LWR) cores. The multiphysics aspects cover the distribution of neutrons, the fluid flow of the coolant and the conjugate heat transfer between the solid fuel pins and the fluid coolant. READ MORE

  6. 24. Development of Accurate Reduced Order Models in a Simulation Tool for Turbomachinery Aeromechanical Phenomena

    Author : Mauricio Gutierrez Salas; Björn Laumert; Paul Petrie-Repar; Damian Vogt; Carlos Martel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flutter; forced response; high cycle fatigue; reduced order models; ROM; craig-bampton; mistuning; tuned; mistuned; cyclic; noncyclic; craig-chang; free-interface. fixed-interface; subset nominal mode; SNM; CBMS; CCMS; CCC; CBC; FEM; CMS; modal; eigen; modeshapes; aeroelasticity; aeromechanical; tool; turbomachinery; turbine; compressor; AROMA; Energy Technology; Energiteknik;

    Abstract : Modern gas turbines are still vulnerable to vibrations when operated at certain speeds. This unstable environment can lead to high cycle fatigue (HCF) and damage several of the components inside the turbine. READ MORE

  7. 25. Effective development of haptic devices using a model-based and simulation-driven design approach

    Author : Aftab Ahmad; Kjell Andersson; Damien Chablat; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Haptic device; model-based design; design optimization;

    Abstract : Virtual reality (VR)-based surgical simulators using haptic devices can increase the effectiveness of surgical training for surgeons when performing surgical procedures in hard tissues such as bones or teeth milling. The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device, which reflects the interaction with the virtual model. READ MORE
