16. 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)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.

17. Breathing Effects in Proton Scanning for Hodgkin's Lymphoma
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Purpose/Background Proton beam scanning (PBS) for mediastinal Hodgkin's Lymphoma (HL) is limited when treating in free-breathing (FB) due to breathing motion in the thoracic region. Tumour motion and the time structure of the beam delivery will cause interplay and dose blurring effects, resulting in discrepancies of dose in the planned dose distribution both inside and at the edges of tumour volume (TV).

18. Rheology of dense particle suspensions in linear over-damped flow
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. While hydrodynamic interactions or lubrication forces between the particles are important in the dilute regime, they become of lesser significance when the concentration is increased, and direct particle contacts become dominant in the rheological response of concentrated suspensions, particularly those close to the maximum volume fraction where the suspension ceases to flow.

19. An automated unmanned aerial vehicle – structure from motion pipeline to create analysis-ready digital surface models for coastal monitoring
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. LÄS MER
20. Benchmarking VisualInertial Odometry Filterbased Methods for Vehicles
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Autonomous navigation has the opportunity to make roads safer and help perform search and rescue missions by reducing human error. Odometry methods are essential to allow for autonomous navigation because they estimate how the robot will move based on the available sensors. LÄS MER
