  1. 1. Effects of water-vapor on the Ka/Q band Earth-space radio propagation channel

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Joar Marchner Brandt; [2021]
    Nyckelord :Attenuation Alphasat Water-vapor Oxygen Cloud ITU Budapest;

    Sammanfattning : A higher frequency radio channel both increase the possible data rate and de- crease the required antenna size to efficiently transmit data. Higher frequency also introduce larger weakness to signal loss due to atmospheric effects. Al- phasat satellite conduct experiments for future use of higher frequencies by the Aldo Paraboni Payload.

  3. 2. Evaluation of the test procedure for a Rubber Balloon Soil Densitometer

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Mohammad Minhajur Ahmed; [2021]
    Nyckelord :Rubber Balloon Soil Densitometer; compacted soil; density; volumetric measurement; artificial pits.;

    Sammanfattning : A Rubber Balloon Soil Densitometer is one of the essential apparatuses in Geotechnical Engineering to measure the in-place volume of compacted soil to calculate the soil density. In 2019, some renowned institutions and organizations, Vattenfall, Luleå University of Technology, Uppsala University, Lund University, and HydroResearch AB, were involved in a research project.

  4. 3. Analysis of Observed Discrepancies in Precipitation Measurements in the Complex Terrain of East-Iceland

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Páll Ágúst Þórarinsson; [2021]
    Nyckelord :Precipitation; precipitation measurements; weather observation; complex terrain; weather regimes; Iceland; Nederbörd; nederbördmätningar; väder observationer; komplex terräng; vädersituationen; Island;

    Sammanfattning : Spatial distribution of precipitation in complex terrain can be very uneven and there are many factors to consider when studying it. The goal of this study was such a problem; to analyse the difference in observed annual precipitation in the complex terrain of Seyðisfjörður, a fjord in East-Iceland. The study was carried out in three parts. LÄS MER

  5. 4. Markberedning med grävmaskin i blockrik terräng : skopbreddens påverkan på resultatet

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Marcus Sahlin; [2017]
    Nyckelord :Markbehandling; Föryngring; Jordbearbetning;

    Sammanfattning : This report was made on behalf of Stora Enso Skog AB. It deals with site preparation on two clearcuts in boulder-rich terrain. Because of the rocky terrain, the scarification was made with excavators, one equipped with a wide bucket and one equipped with a narrow bucket. LÄS MER

  7. 5. Strategies for High Frequency FX Trading - The choice of bucket size

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Malin Lunsjö; Malin Riddarström; [2017]
    Nyckelord :Highfrequency; FXtrading; Shiftedgeometricdistribution; MonteCarlo; Time Series Analysis; EWMA; Bucket size; TWAP.; Mathematics and Statistics;

    Sammanfattning : This thesis aims at developing and evaluating a model for high frequency foreign exchange data, that beats the TWAP benchmark the majority of the time. This is done by dividing the total order time into smaller time buckets and trading a smaller quantity of the total order volume in each bucket. LÄS MER
