  1. 1. Influence from long-distance transport, local sources and precipitation on black carbon concentrations at a rural background field station in southern Sweden

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

    Författare :Kit Ming Yam; [2019]
    Nyckelord :Black carbon; black carbon concentrations; Hyltemossa station; Aethalometer; HYSPLIT; long-distance transport; local sources; precipitation; Physics and Astronomy; Earth and Environmental Sciences;

    Sammanfattning : The year 2018 was the first complete year with aerosol observations at the rural background station Hyltemossa in southern Sweden. The aim of this thesis was to analyse and investigate the influence from long-distance transport (LDT) aerosols, local sources and precipitation on the black carbon (BC) mass concentration by utilising the Aethalometer and the HYSPLIT model, which estimated the BC mass concentration ([BC]) and simulated the origin of the LDT air masses to Hyltemossa, respectively.

The performance and applicability of the most promising or popular small scale energy harvesting technologies are investigated in this thesis. LÄS MER

  4. 3. Ethernet Energy Harvesting

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Sukru Senli; [2012]
    Nyckelord :Ethernet Energy Harvesting; Energy Harvesting; Energy Scavenging; Ethernet Power;

    Sammanfattning : Improvements in embedded electronics which have effectively reduced power consumption requirements as well as advancements in IC technology allowing utilization of low power inputs have made Energy Harvesting a popular power solution for low power applications such as WSNs. In many implementation areas, we can see solar, thermal, and vibration energy harvesting techniques have taken the role of batteries as power source. LÄS MER
