  1. 1. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Jessica McKenna; [2023]
    Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Abstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  3. 2. Analysis of performance data of wind turbines for polar regions

    University essay from Uppsala universitet/Högenergifysik

    Author : Arnau Serra Garet; [2023]
    Keywords : ;

    Abstract : The Radio Neutrino Observatory in Greenland is situated at Summit Station. Due to its isolatedlocation the main power to support the autonomous radio stations is solar energy. However,during the winter months when there is no sun another strategy needs to be found. READ MORE

  4. 3. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Pablo Martinez Cano; [2019]
    Keywords : LISA; PCB; temperature; passive; aluminum; aluminium;

    Abstract : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.

  5. 4. Detectability of fiducial markers in an MRI-only radiotherapy treatment workflow for prostate

    University essay from Lunds universitet/Fysiska institutionen

    Author : Sevgi Emin; [2017]
    Keywords : prostate cancer; fiducial markers; CT; MRI; MRI-only workflow; Physics and Astronomy;

    Abstract : In a conventional prostate cancer radiotherapy treatment workflow, computed tomography (CT) and magnetic resonance imaging (MRI) are used for radiotherapy treatment planning and target delineation. MRI is necessary in the process due to better soft tissue contrast compared to CT-images. READ MORE

  6. 5. A New Controller for the Acquisition and Guiding Unit for the Gemini South Telescope : New architecture and control schemes to use Power PMAC

    University essay from KTH/Optimeringslära och systemteori

    Author : Matthieu Barreau; [2016]
    Keywords : ;

    Abstract : When the Gemini Telescopes were built 20 years ago, the control architecture for the high precision requirements was the same for all systems. It consisted of VME cards, Programmable Multi Axis Con-trollers (PMAC) with specific amplifiers and a central computer. It was the state of the art. READ MORE
