6. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads
Master-uppsats, KTH/EnergiteknikSammanfattning : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. LÄS MER
7. The Dirichlet-Neumann iteration – Three-field case: Methods and analyses
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : We construct and analyze Dirichlet-Neumann iterations for the 1D Poisson equation. Specifically, we wish to gain insight into how the convergence depends on material coefficients when solving coupled linear heat equations on three non-overlapping domains. We first consider the two-domain case and then extend the method to three domains. LÄS MER
8. Additive weld manufacturing and material properties effect on structural margins
Master-uppsats, KTH/LättkonstruktionerSammanfattning : the FE analyses. Traditionally all parts are modeled with isotropic base material. Analyses are made on a part of the nozzle which includes both a butt weld and metal deposition and which is an interface to another part causing loads that has to be sustained by the weld and the MD.

9. Bästa samlingen är att bygga en raket av papper : En emprisk undersökning om barns inflytande och delaktighet under samlingen i förskolan
M1-uppsats, Södertörns högskola/LärarutbildningenSammanfattning : The purpose of this study is to emphasize the democratic term. We wanted to study how pedagogues act and deal with their own feelings, when they meet the thoughts and feelings of the children around the topic gathering in preschool. Our starting point was the answers from the interviews we held. LÄS MER
10. Radarupptäckt av artilleriraketer
Kandidat-uppsats, FörsvarshögskolanSammanfattning : Denna rapport behandlar en radarsensors förmåga att upptäcka 107 mm raketerberoende på hur sensorn positioneras i förhållande till skyddsobjektet.Fältförsök, underrättelser och stridserfarenheter har visat att dessa raketer ärvanligt förekommande samt svåra att detektera med radarsensorer.
