  1. 1. Microwave substrate filter implementationfor an advanced 5G antenna system

    University essay from Högskolan i Halmstad

    Author : Arhayem M Bashar; [2021]
    Keywords : ;

    Abstract : This master thesis has been done at Ericsson AB (2018) in collaboration with LeonardoPadial Torán. Microwave filters for the future 5G have become an increasingly interesting researchtopic. The conventional design theory of microwave filters is no longer valid. READ MORE

  2. 2. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Oskar Evert Johansson; [2021]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Abstract : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. READ MORE

  3. 3. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Holmér; [2021]
    Keywords : ;

    Abstract : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

  4. 4. A sensor orientation and signal preprocessing study of a personal fall detection algorithm

    University essay from Högskolan Kristianstad/Fakulteten för naturvetenskap

    Author : Viktor Johansson; [2020]
    Keywords : Decision tree; fall detection algorithm; machine learning; smartphone; accelerometer; gyroscope; low-pass filter;

    Abstract : This study investigates if a smartphones orientation in the pocket affects the result of a decision tree model trained with data from personal falls, and also how a low-pass filter affects these results. A comparison is made between the results gathered from this study, compared to previous studies and products within the field. READ MORE

  5. 5. Filter Design for an HVDC protection IED

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

    Author : Evgeny Genov; [2020]
    Keywords : ;

    Abstract : A selective fault detection approach is necessary for successful implementation of multi-terminal high-voltage direct-current (HVDC) grids. Fault detection is per- formed by an intelligent electronic device (IED) that takes in voltage and current measurements, performs fault detection algorithms, and outputs, e.g. READ MORE
