  1. 6. Galaxy evolution in extreme environments

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Samhitha Vadlamani; [2019]
    Keywords : Galaxy evolution; interactions; starburst; Compact galaxy groups; Stephan s Quintet; Physics and Astronomy;

    Abstract : Interactions play a crucial role in determining how galaxies evolve in terms of their morphologies and star formation histories, since the majority of the known galaxies in the nearby Universe are found to exist in groups. Compact groups of galaxies are of particular interest as they contain a small number of galaxies in dense configurations and host repeated interactions between them, enabling us to capture signatures of these interactions (e.

  3. 7. Generation of a full-envelope hydrodynamic database for hydrobatic AUVs : Combining numerical, semi-empirical methods to calculate AUV hydrodynamic coefficients

    University essay from KTH/Marina system

    Author : Tianlei Miao; [2019]
    Keywords : AUV; hydrodynamic coefficients; database; Jorgensen method; DATCOM method; CFD; Simulink simulator; data confidence level;

    Abstract : The next generation of Autonomous Underwater Vehicles (AUV) can impact our observation of the world. The flight simulation and full-envelope hydrodynamics modeling can improve the performance of AUVs in terms of control, navigation and positioning. READ MORE

  4. 8. Evaluation of SPH for hydrodynamic modeling,using DualSPHysics

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Jonas Eriksson; [2018]
    Keywords : ;

    Abstract : Computational methods are always being invented, improved and adjusted to newkinds of problems, this is a constant process happening all the time. The studyevaluates a method called Smoothed Particle Hydrodynamics (SPH) for modelingon fluid flows around ship hulls. This has been done mainly using a open sourcecode called DualSPHysics.

  5. 9. Nanoparticle Removal and Brownian Diffusion by Virus Removal Filters: Theoretical and Experimental Study

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Olof Gustafsson; [2017]
    Keywords : virus removal filtration; Péclet number; nanocellulose; hydrodynamic constraint; convective capture; diffusion;

    Abstract : This study aims to examine the throughput of nanoparticles through a Cladophora cellulose based virus removal filter. The effect of Brownian motion and flow velocity on the retention of 5 nm gold nanoparticles, 12.8 nm dextran nanoparticles and 28 nm ΦX174 bacteriophages was examined through MATLAB simulations and filtration experiments.

  6. 10. Modeling and Concept Design of Wave Energy Device

    University essay from KTH/Marina system

    Author : Rickard Holmgren; [2016]
    Keywords : ;

    Abstract : It has been suggested that it is feasible to extract energy from ocean waves which may be used to generate electricity. This thesis is centered on a wave energy converter system, which is known as a point absorber, which in its most simple design may be seen as a buoy moving up and down due to the wave motions.
