  1. 1. Determining shallow P-wave velocity and its engineering implication in Adama City, Ethiopia

    Kandidat-uppsats, Uppsala universitet/GeofysikUppsala universitet/Institutionen för teknikvetenskaper

    Författare :Tasnim Laskar; [2019]
    Nyckelord :Ethiopia; seismic refraction; earthquake;

    Sammanfattning : A great number of the urban areas in Ethiopia are situated within the Great Rift Valley of Ethiopia, a system consisting of depressions and large faults. As a region with significant seismic activities, it is vital that careful planning is implemented to avoid constructing buildings on flat surfaces as they can amplify ground motion in the case of an earthquake.

  2. 2. Undersökning av asfaltbruk med olika fillersorter

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och väg

    Författare :Ola Aurell; [2019]
    Nyckelord :Bitumen; Filler; Asfaltsbruk; Reologi; DSR; dynamisk skjuvreometer; Technology and Engineering;

    Sammanfattning : The properties of asphalt mastic, consisting of bitumen and filler, determine the asphalt's resilience and stability and ultimately durability. The reason to why asphalt mastics hasn’t been more in focus is probably the lack of an established methodology for measurement. LÄS MER

  3. 3. Undersökning av viskositet hos asfaltbruk - Mätningar med rotationsviskosimeter på bruk med olika fillersorter och mängder

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och väg

    Författare :Max Rosqvist; [2019]
    Nyckelord :Filler; bitumen; asfaltbruk; viskositet; rotationsviskosimeter; Technology and Engineering;

    Sammanfattning : Bitumen och dess egenskaper har länge ansetts vara den viktigaste faktorn för en asfalts funktion. Egenskaperna som finns är hos bitumen är relativt enkla att kontrollera. LÄS MER

  4. 4. Miniaturization of a Low Power Harmonic Radar for UAV use

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

    Författare :Saleh Aljaser; [2019]
    Nyckelord :Harmonic; Radar; Insects; Tracking; Detection; UAV; FMCW; Small; Low Power; Wireless; Communications; Technology and Engineering;

    Sammanfattning : The aim with this Master thesis work is to design, build and test a small size, light weight and low power consumption harmonic radar system that will be installed in a flying drone for the purpose of tracking and localizing tagged Bogong moths near their aestivation caves and crevices in Australia during summer. A FMCW harmonic radar is proposed, it comprises a radar transmitter, receiver and a signal processor. LÄS MER

  5. 5. Artificial intelligence to model bedrock depth uncertainty

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Beatriz Machado; [2019]
    Nyckelord :Machine learning; Artificial intelligence; Kriging; prediction; algorithm.;

    Sammanfattning : The estimation of bedrock level for soil and rock engineering is a challenge associated to many uncertainties. Nowadays, this estimation is performed by geotechnical or geophysics investigations. These methods are expensive techniques, that normally are not fully used because of limited budget. LÄS MER
