  1. 1. Low-Frequency Noise in InGaAs Nanowire MOSFETs

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Christian Mario Möhle; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Low-frequency (LF) noise (1/f as well as random telegraph-signal (RTS) noise) measurements were performed on high-performance InGaAs nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs). 1/f noise measurements at room temperature (RT) show that the dominant noise mechanism is carrier number fluctuations.

  2. 2. Evaluation of Seasonal Inflow Forecasting to Support Multipurpose Reservoir Management: A case study for the Upper Maule River Basin, Chile

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Johan Visser; [2017]
    Nyckelord :Seasonal Forecasting; Reservoir Management; Ensemble Streamflow Prediction; Downscaling; Maule; Earth and Environmental Sciences;

    Sammanfattning : Seasonal hydrological forecasts of future streamflow volumes can provide water resources managers with valuable information to improve long-term water resources planning and water use efficiency. The latest generation of coupled ocean-atmosphere general circulation models provides an opportunity for the prediction of hydroclimatic variables (e.g. LÄS MER

  3. 3. Reconstructing the Long-Term Mass Balance of Brewster Glacier, New Zealand, Using a Degree-Day Approach

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Rikard Palmgren; [2017]
    Nyckelord :Mass balance; DDM; climate indicator; glacier; New Zealand; Massbalans; DDM; klimatindikator; glaciär; Nya Zeeland;

    Sammanfattning : Varmare klimat är något som kontinuerligt påverkar glaciärer planeten över och har under det senaste århundrandet vidtagit en global ökning av negativa massbalanser. Denna trend kan bidra till variationer i havsnivån och orsaka problem med översvämningar över hela världen. LÄS MER

  4. 4. GaSb nanowire transistors with process induced strain

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Edvin Winqvist; [2017]
    Nyckelord :GaSb; gallium; antimonide; nanowire; transistor; strain; physics; thesis; Physics and Astronomy;

    Sammanfattning : With the constant downscaling of Si transistors reaching its limits, other alternatives have been actively researched the past decades. Group III-V semiconductors are excellent materials with generally high carrier mobilities that can replace Si in transistors. LÄS MER

  5. 5. Quantifying the Shadow Effect between Offshore Wind Farms with Idealized Mesoscale Models and Observed Wind Data

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :David Werner; [2016]
    Nyckelord :Shadow effect; offshore wakes; atmospheric stability; analog ensemble; wake forecasting; idealized mesoscale modeling; Weather Research Forecast WRF model; downscaling; North Sea; Princes Amalia; Egmond aan Zee;

    Sammanfattning : Two post processing methods for quantifying the shadow effect of the offshore wind farm Princes Amalia (PA) onto Egmond aan Zee (OWEZ) wind farm are analyzed and benchmarked. The first method is the author’s proposed shadow effect determination method (SEDM), which quantifies an offshore wind farm’s shadow effect based on mesoscale WRF (Weather Research Forecast) idealized modeling and the observed frequency of the analyzed site’s wind conditions.
