21. Common Envelope Evolution
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : We present simulations done on the onset of common envelope evolution with giant donors by taking into account the mass loss through the outer Lagrange point and the forming of the common envelope. In addition we apply proper stellar models and evolve our simulations using an Runge-Kutta integrator with adaptive step-size. READ MORE

22. Numerical Investigations of a Partitioned FSI Algorithm for Tetra Pak's Filling Tube
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : Numerical simulations of fluid-structure interaction of a water-filled tube with a free surface are conducted using an implicit partitioned coupling scheme. Abaqus and STAR-CCM+ are used for the solid- and fluid domains respectively. This application has stability issues, with the most severe turning out to be the added mass effect. READ MORE

23. Dark Ages Lunar Interferometer - Deployment Rover : Propulsion and Steering Systems
University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskapAbstract : 2030 NASA Jet Propulsion Laboratory will place an interferometer, which will workas a radio telescope, on the far side of the Moon. The interferometer uses thinpolyamide films as antennas, which are rolled out by a rover (an autonomousvehicle). The thesis covers concept generation of the propulsion and steering systemof the rover. READ MORE

24. High Resolution Filter for Stable Spacecraft Attitude Estimation
University essay from KTH/Optimeringslära och systemteoriAbstract : In this thesis a filter for attitude estimation using sensor fusion of a Star Tracker and a Gyroscope are designed and implemented for integration on the European Data Relay satellite, EDRS. The performance of three filters, Multiplicative Extended Kalman Filter, Unscented Kalman Filter and Particle filter, are evaluated in terms of attitude error, covariance convergence and change of attitude knowledge uncertainty.

25. The effect of dark matter capture on binary stars
University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : WIMPs, orWeakly InteractingMassive Particles, are a popular dark matter candidate, but their detection remains elusive. At its core, this project is an effort to bridge the gap between the theory of WIMPs, and astronomical observation. READ MORE
