1. Computational Fluid Dynamics and Modeling of a Free Surface Flow
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. LÄS MER
2. Parabolic equation models simulating LoS MIMO conditions
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : This thesis explores and develops a simulation model for Line of Sight(LoS) Multiple-Input Multiple-Output (MIMO) systems in complex environments. The focus will be on implementing a 2 × 2-MIMO system in order to study phase differences of the received signals. LÄS MER
3. CFD-modeling of labyrinth weir flood discharge with ice cover
Master-uppsats, KTH/BetongbyggnadSammanfattning : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. LÄS MER
4. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER
5. Ray-tracing Based Investigations on the Deployment of RISs in Indoor Scenarios
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. LÄS MER
