  1. 16. WIDE RANGE BI-DIRECTIONAL DC-DC CONVERTER

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Ali Rezaee; [2021]
    Keywords : Keywords: Bidirectional Converter; Phase Shifted Full Bridge; Soft Switching; Wide Input–WideOutput;

    Abstract : Bi-directional DC-DC converters are used for applications that require a flow of energy in two directions, while a wide range converter offer efficient operation over a wide range of input and output voltages. However, an efficient technology that is both bi-directional and Wide Input Wide Output (WIWO), currently, does not currently exist. READ MORE

  3. 17. Fatigue Testing of a Unidirectional Carbon Fiber Reinforced Polymer : Investigation of damage development using Digital Image Correlation

    University essay from KTH/Lättkonstruktioner

    Author : Lars Johan Wenner Berg; [2020]
    Keywords : ;

    Abstract : Carbon Fibre Reinforced Plastic (CFRP) is a material with high specific propertiesand good fatigue and vibration dampening characteristics, and can potentiallybe used instead of steel and aluminium in heavy duty vehicles. This work focuseson testing methodology and the fatigue properties of a unidirectional (UD)material in the 0° and 90°orientation, reproducing and validating the method developedby Wanner[1].

  4. 18. Can I and AI be Friends? : Robots and personal relationships

    University essay from Umeå universitet/Institutionen för idé- och samhällsstudier

    Author : Tâm Beran; [2020]
    Keywords : AI; robots; personal relationships; friends; AI; robot; personliga relationer; vänner;

    Abstract : To exist is to relate. As human, you are relating to other beings, animate and inanimate entities, physical objects and abstract ideas. A kind of relationship that affects our life and wellbeing in a most concrete sense is that between humans. READ MORE

  5. 19. Effect of Induction-Heat Post-Curing on Residual Stresses in Fast-Curing Carbon Fibre Reinforced Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mercedes Amelia Bettelli; [2020]
    Keywords : Carbon Fibres Reinforced Polymer Composite; epoxy resins; cure behaviour; residual stress and shape distortions;

    Abstract : Manufacturing induced shape distortions is a common problem for composite materials. Due to the non-isotropic nature of carbon fibre reinforced polymers (CFRP) unavoidable deformations occur during part production. During fabrication of polymer composites, the material obtains its final shape at elevated temperatures. READ MORE

  6. 20. Biocomposite with Continuous Spun Cellulose Fibers

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Rocio Nahir Pineda; [2020]
    Keywords : cellulose fibers; biocomposite; vacuum infusion process; film-stacking process; polylactic acid;

    Abstract : The subject of this project is to study spun cellulose fibers made by Spinnova Oy inFinland. The fibers are spun using an environmentally friendly spinning process withoutuse of harsh chemicals. READ MORE
