  1. 16. Energy renovation packages for the decarbonisation of Swedish multifamily buildings

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Bhavik Daya; Hugh Nolan; [2022]
    Keywords : Decarbonisation; Renovation; Multi-family homes; Life Cycle Assessment; Life Cycle Costing; Technology and Engineering;

    Abstract : Sweden and Europe aim to be carbon neutral by 2045 and 2050 respectively. Upgrading the existing building stock has been identified as having great potential in assisting to realise these goals. READ MORE

  3. 17. Head impact detection with sensor fusion and machine learning

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Aron Strandberg; [2022]
    Keywords : head impact detection; sensor fusion; 3D; machine learning; support vector machine; random forests;

    Abstract : Head injury is common in many different sports and elsewhere, and is often associated with differentdifficulties. One major problem is to identify and value the injury or the severity. Sometimes there is no sign of head injury, but a serious neck distortion has occurred, causing similar symptoms as head injuries e.g. READ MORE

  4. 18. Design of radio frequency energy harvesting system : for use in implantable sensors

    University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

    Author : Amir Ebrahimi; David Kihlberg; [2022]
    Keywords : RF energy harvesting; RF rectifier; efficiency; voltage sensor; voltage doubler;

    Abstract : Implantable biomedical wireless sensors provide monitoring of vital health signs such as oxygen, temperature and intraocular pressure and may help to analyse and detect diseases in humans and animals. However, one of the design challenges of implantable devices is providing a safe and reliable energy source. READ MORE

  5. 19. Use of the JET pedestal database to assess the role of ion temperature and plasma rotation on the discrepancy between ideal peeling-ballooning model and experimental data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Max Eichenberger; [2022]
    Keywords : Nuclear fusion; Joint European Torus JET ; H-mode; pedestal; Edge-localized-modes ELMs ; Peeling-Ballooning; relative shift; ion temperature; plasma rotation; Kärnfusion; JET Joint European Torus ; H-läge; piedestal; ELM Edge Localized­Modes ; peeling-ballooning; relativ förskjutning; jontemperatur; plasmarotation;

    Abstract : Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components.

  6. 20. Characterization of surface defects caused by ultrasonic cleaning of aluminium

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Emanuel Eriksson; [2022]
    Keywords : Ultrasonic cleaning; surface cleaning; metal; aluminium; 7050; 2050; defects; surface defects; Energy Dispersive Spectroscopy; Scanning Electron Microscopy; Vertical Scanning Interferometry;

    Abstract : This master thesis studies the behaviour of two aluminium alloys in ultrasonic cleaning at two different intensities, as well as the effect of a cleaning solution, Formula 815 GD-NF on the same surface have been studied with respect to surface roughness and material composition. Methods like Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and 3D topography using white light interferometry (VSI) was used to study the surface and material composition.
