    Författare :Maria Halvarsson; Jinglan Qin; [2022]
    Nyckelord :Indoor positioning system; Bluetooth Low Energy; Relational database; AWS cloud services; Indoor asset tracking; Indoor navigation; Indoor localization; Database design; Inomhuspositioneringssystem; Bluetooth Low Energy; Relationsdatabas; AWS molntjänster; Tillgångsspårning; Inomhusnavigering; Inomhuslokalisering; Databasdesign;

    Sammanfattning : Indoor Positioning System (IPS) are becoming more common in many areas such as retail, warehouses, smart facilities, and manufacturing.In recent years, Bluetooth Low Energy (BLE)-based IPS has become increasingly popular due to its low cost and low energy consumption. One of the more recent updates, Bluetooth 5. LÄS MER

  3. 2. Fluoride removal by low-cost adsorbents

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Fredrik Bernheim; [2022]
    Nyckelord :Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Sammanfattning : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. LÄS MER

  4. 3. Study of antenna arrays for direction finding

    Sammanfattning : The new Bluetooth standard (Bluetooth 5.1) contains direction finding specifications. Specifications for received signal strength indicator(RSSI) using measures of signal strength in order to give a sense of how far away an object is has been present in earlier versions. LÄS MER

  5. 4. Analysis of the Stratospheric Aerosol Load After the 2019 Raikoke Eruption

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

    Författare :Felicia Carlborg; [2021]
    Nyckelord :Volcanic Climate Impact; Raikoke; CALIPSO; Satellite; Stratospheric Aerosols; Radiative Forcing; Aerosol Optical Depth; Physics and Astronomy;

    Sammanfattning : The stratospheric aerosol load after the eruption of Raikoke in 2019 have been analysed with satellite data from the CALIPSO satellite. The goal was to see how much the stratospheric aerosol load increased due to the Brewer Dobson circulation, and further, how this affected the stratospheric aerosol optical depth (AOD), and the corresponding radiative forcing (RF).

  7. 5. Characterization of phases in Argon Oxygen Decarburization slag

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Emil Rosqvist; Theodore Vassi; [2021]
    Nyckelord :;

    Sammanfattning : Slag is an important part of steelmaking with the AOD (Argon Oxygen Decarburization) process. In this work the focus was on developing a methodology for characterizing phases in slagsamples obtained after decarburization, reduction and desulphurization. LÄS MER
