  1. 1. Evaluation of structurally controlled rockfall hazard for underground excavations in seismically active areas of the Kiirunavaara mine

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

    Författare :Manuel Alberto Fuentes Espinoza; [2023]
    Nyckelord :Structurally controlled rockfalls; rockfalls due to seismic shaking; sublevel caving; fork layout; Unwedge; wedge analysis; deterministic analysis; probabilistic analysis;

    Sammanfattning : Sublevel caving operations at great depths are subjected both to large stress concentrations that are redistributed as the mining front progresses and to mining-induced seismicity. This is the case for Kiirunavaara mine, Sweden’s largest underground mine. LÄS MER

  3. 2. Measuring Acoustic Mobility of Particles by Particle Tracking Velocimetry

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Alexander Edthofer; [2022]
    Nyckelord :acoustophoresis; microfluidics; polystyrene; cells; particle tracking velocimetry; Technology and Engineering;

    Sammanfattning : Acoustophoresis is a method to manipulate and move cells or particles suspended in a medium using acoustic waves. The speed of the acoustophoretic motion depends on the cells' acoustic mobility, i.e. their size, density and compressibility relative to the medium. LÄS MER

  4. 3. Radar Detection Using Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Ziliang Xiong; Leonardo Carrera; [2022]
    Nyckelord :Deep Learning; Autonomous Driving; Radar; Point Cloud; Technology and Engineering;

    Sammanfattning : This thesis aims to reproduce and improve a paper about dynamic road user detection on 2D bird's-eye-view radar point cloud in the context of autonomous driving. We choose RadarScenes, a recent large public dataset, to train and test deep neural networks. LÄS MER

  5. 4. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Linnéa Tebelius; [2022]
    Nyckelord :Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

    Sammanfattning : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.

  7. 5. Modelling development of ECMO return flow in bifurcating arteries

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Friederike Schäfer; [2021]
    Nyckelord :Fluid Mechanics; CFD; ECMO;

    Sammanfattning : Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is a life saving therapy for critically ill patients experiencing a heart and lung failure. During this therapy, a common complication is limb ischemia in the leg where the return cannula reintroduces the oxygenated blood to the patient. LÄS MER
