1. Simulations of a self-stabilizing fully submerged hydrofoil
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : Two models of a self-stabilizing hydrofoil system is developed where the effects from the struts and hydrofoil give torques for angular rotations. Lifting line theory for the hydrofoil which can twist is used. Nonlinear versions of the models are also developed and compared to find that the linear models use valid approximations. LÄS MER
2. Nu stannar vi på marken : En kvalitativ semiotisk analys av SJ:s hållbarhetskommunikation
Kandidat-uppsats, Jönköping University/HLK, Medie- och kommunikationsvetenskapSammanfattning : Studien ”Nu stannar vi på marken” ämnar analysera hur företaget SJ konstruerar sin hållbarhetskommunikation och om greenwashing-fenomenet ses i deras reklam och iså fall i vilken grad. Greenwashing anges när ett företag sprider vilseledande information för att få företaget att framstå mer hållbara än vad de egentligen är, för att locka konsumenter. LÄS MER
3. Longitudinal Flight Mechanics of Paraglider Systems
Master-uppsats, KTH/FlygdynamikSammanfattning : This project outlines a cost-effective numerical simulation method for the analysis of the longitudinal mechanics of paraglider systems. It is built on static stability methods for the analyses of low subsonic aircraft, non-linear lifting line methods for aerodynamic parameterization, and frequency domain analysis methods derived from system theory.

4. Study of tip clearance flows
Master-uppsats, KTH/FlygdynamikSammanfattning : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. LÄS MER
