  1. 1. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

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

    Författare :Diogo Antunes; [2023]
    Nyckelord :Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Sammanfattning : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.

    Sammanfattning : Magnetic resonance imaging (MRI) is a critical diagnostic tool in medical practice, enabling non-invasive visualization of anatomy and physiological processes. Nonetheless, MRI has inherent spatial resolution limitations, which may limit its diagnostic capabilities. LÄS MER

  4. 3. 1D Simulation of Hydraulic Cam Phaser System Utilized in Heavy Duty Vehicles : An Investigation on Attenuation of Phase Oscillations from Cam Torque Disturbances

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johan Germundsson; [2023]
    Nyckelord :master thesis; cam phaser; simulation; 1D-simulation; GT-SUITE; GT-ISE; Gamma Technologies; oil aeration; oscillations; heavy-duty; engine; phaser; cam torque; stability; cam phaser system; Scania; Scalia CV;

    Sammanfattning : Cam phasers allow improvements to the efficiency and emissions of internal combustion engines. The usage of hydraulic vane type cam phasers for heavy-duty applications have shown problems with oscillations during testing at Scania CV. To investigate the root cause of the oscillations a detailed 1-d simulation model has been created. LÄS MER

  5. 4. Probabilistic settlement analysis for embankments using preloading without surcharge

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Karl Escher; [2022]
    Nyckelord :Bayesian statistics; uncertainty; geotechnical risk evaluation; preloading; consolidation; embankments; ground improvement; dependence modelling.;

    Sammanfattning : Preloading without a surcharge is a common method for ground improvement. Thereare however uncertainties related to the number of site investigations and the partialfactor method has been identified as a problem. LÄS MER

  7. 5. Improvement of the 1D CFD method for Thermal management of a Battery Electric Vehicle

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :SASHWAT CHHETRI; [2022]
    Nyckelord :CFD; Electromobility; BEV; Thermal Management; Simulation;

    Sammanfattning : Electrification of vehicles is necessary to combat greenhouse gas emissions, whichcauses global warming and climate change. There has been a demand in the use ofBattery Electric Vehicles due to this increased awareness of sustainability. However,they have been beset with issues such as range and conservation of energy.
