  1. 11. The Examination of Alternative Methods for Sperm Cell Lysis and Purification of Sexual Assault Samples

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Emilie Boson; [2023]
    Nyckelord :Differential lysis; Differential extraction; Sexual assault samples; Sperm cells; Forensic; DNA recovery; DNA profiling; DNA purification; Applied microbiology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. LÄS MER

  3. 12. Current-Mode Class D Power Amplifier for 2.4GHz Wi-Fi

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yann Jean Michael Pirot; [2023]
    Nyckelord :Power Amplifier; Wifi; Digital Power Amplfier; Class D; RFIC; Analogue; Effektförstärkare; Wifi; digital förstärkare; klass D; analog;

    Sammanfattning : Modern wireless communication techniques employed in the Wi-Fi® protocol, such as orthogonal frequency-division multiplexing exhibit analogue signals with high peak-to-average power ratio. Therefore, power amplifiers for Wi-Fi suffer from low efficiency when operating in back-off mode, away from their maximum efficiency at peak power. LÄS MER

  4. 13. Beam selection using Machine Learning in Massive MIMO systems

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Simon Persson; [2023]
    Nyckelord :Massive MIMO; Beamforming; Machine Learning; 5G; NR; Antenna selection; Technology and Engineering;

    Sammanfattning : In mobile communications the demand for increased capacity and speeds is a constant. 5G NR is the latest generation which is now seeing widespread adoption. Crucial technologies like Massive MIMO and beamforming are enabled by the use of large antenna arrays. LÄS MER

  5. 14. Energilager i kyrkan och dess systemnyttor : Batterier i kyrkan och hur de kan bidra till ett stabilare elnät

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Axel Eriksson; David Norman; [2023]
    Nyckelord :stödtjänster; batterisystem; energilager; peakshawing; spänningsreglering; flexibilitetsmarknader; kyrkan;

    Sammanfattning : Many of the over 3300 churches in Sweden are only used a couple of times a week and are kept cold in between sessions. The occasional heating results in a power spike which burdens both grid and wallet in form of an increased grid fee. With the help of a battery and peak shaving, the peak can be lessened. LÄS MER

  7. 15. Changing Transport Strategy to Off-Peak Hour Delivery in Gothenburg and Copenhagen - Lessons and Recommendations learned from the New York and Stockholm Pilot Projects

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Diego Henriquez; Konstantinos Stavrou; [2022-08-03]
    Nyckelord :Off-Peak Hour Delivery; Urban Freight Transport; Stakeholders; Traffic Congestion; Environmental Pollution; Electric Vehicle;

    Sammanfattning : The pattern of urbanisation is determined by a set of complex aspects in social, economic, environmental, as well as technological that increases the concentration of the population in urban settlements. Many cities are experiencing difficulties and immense pressure on the infrastructure by declining traffic conditions with a series of issues including longer transit times, increased fuel consumption, and greenhouse gas emissions, prompting stakeholders and policymakers to tackle the issue by introducing alternative solutions to utilise the urban infrastructure more efficiently.
