  1. 1. Antenna Options for High Altitude IMT Base Stations (HIBS) in Cellular Networks

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Harald Magnusson; [2022]
    Nyckelord :High altitude IMT Base Station HIBS ; High Altitude Platform Station HAPS ; Link Feasibility; Coverage Feasibility; Phased Array Antenna; Parabolic Reflector Antenna;

    Sammanfattning : This thesis is the result of a collaboration between Ericsson AB and Luleå University of Technology. A feasibility study has been conducted to investigate antenna options for the HIBS access link. The study contains two parts. Firstly, a link budget investigating the gain required from the antenna.

  3. 2. The effect of thickness and compaction on the recovery of aluminium in recycling of foils in salt flux

    Master-uppsats, KTH/Materialvetenskap

    Författare :Harald Philipson; [2020]
    Nyckelord :;

    Sammanfattning : In Norway, more than 40.000 tonnes of aluminum (Al) in food packaging goes to incineration annually. Recycling this waste would save more than 1.5 TWh of energy and several hundred thousand tonnes of CO2 emissions. LÄS MER

  4. 3. A Transparent Dual-Band Cubesat Antenna Array Based on Stacked Patches

    Kandidat-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Fernando Franzén; Harald Hultin; Jonas Olsson; [2017]
    Nyckelord :;

    Sammanfattning : This work has the scope of developing a transparentantenna for CubeSats. A CubeSat is a type of miniature satellitethat is popular due to cheaper launches and standardized dimensions.Small satellites have a limited surface area which usuallyis covered by solar panels. By making the antenna transparent,it can be mounted on top of the solar panels. LÄS MER

  5. 4. Heat transport in nano materials subject to high intensity nano focused X-rays

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Harald Wallander; [2016]
    Nyckelord :x-rays; nanowire; nanomaterial; InP; synchrotron; nanomax; nanofocus; heat transport; COMSOL; heating; Physics and Astronomy;

    Sammanfattning : The thesis aims to investigate the amount and distribution of heat in nano materials irradiated by highly focused X-ray beams, like those that will be produced by MAX IV. The beam used in the study had a flux of 10e11 photons per second and a diameter of 100 nm. LÄS MER

  7. 5. How Private Car Drivers View Vehicle Ownership during the ‘Clean Vehicles in Stockholm’ Project: - An Exploratory Consumer Case Study Prepared for the City of Stockholm Environment and Health Administration

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för marknadsföring och strategi

    Författare :Harald Fisk; [2008]
    Nyckelord :Alternative fuel vehicles; Incentives; Stockholm; Sustainable transport; Travel demand management;

    Sammanfattning : In response to concerns about climate change the City of Stockholm has set the goal of being entirely fossil fuel free by 2050. One of the ways in which they are attempting to achieve this is through the Clean Vehicles in Stockholm project. LÄS MER
