  1. 1. Feasibility study of initial orbit determination with open astronomical data

    University essay from KTH/Fysik

    Author : Linn Mattsson; [2022]
    Keywords : Space situational awareness; Space surveillance and tracking; Image analyse; Streak detection algorithm; Initial orbit determination; Rymdlägesbild; Bildanalys; Algoritm för streck detektering; Initial banbestämning;

    Abstract : In this report I present a feasibility study of using open astronomical data to make Initial Orbit Determination (IOD) for Resident Space Objects (RSO) appearing as streaks in telescope images. The purpose is to contribute to Space Surveillance and Tracking (SST) for maintaining Space Situation Awareness (SSA). READ MORE

  3. 2. On the Identification of Nonlinear Optima in Spatially Developing Boundary Layer Flow

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Emanuel Taschner; [2021]
    Keywords : transition to turbulence; nonlinear stability analysis; boundary layer flow; övergång till turbulens; icke-linjär stabilitetsanalys; gränsskiktsflöden;

    Abstract : The present thesis studies transition to turbulence in a spatially developing bound-ary layer for subcritical Reynolds numbers. A fully nonlinear iterative direct-adjoint optimisation technique is employed to identify finite amplitude perturbations triggering transition in an energy efficient way. READ MORE

  4. 3. Improving image quality of a streak camera using periodic shadowing

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : David-Gabriel Lange; [2021]
    Keywords : combustion physics; laser; lock-in amplification; laser induced fluorescence; periodic shadowing; Rhodamine B; streak camera; Mode-locking; microfluidics; fluorescence lifetime imaging; Physics and Astronomy;

    Abstract : Stray light suppression using a method inspired by lock-in amplification, called periodic shadowing, is examined and demonstrated for a measurement involving a streak camera. The experiment consists of resolving the fluorescent decay of the dye Rhodamine B (RhB) and examining both the rise and the decay of the fluorescence. READ MORE

  5. 4. Orbit determination of asteroids using streak information

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Samuel Ocana Losada; [2020]
    Keywords : asteroids; orbit determination; streaks; trailed observations;

    Abstract : Asteroids are becoming a stepping stone for the human space exploration,as much as they are a threat for human life on Earth. Several agencies haveproved that sending spacecraft to an asteroid is already feasible so privatecompanies are starting to look into how to exploit this new resources we havenow at hand. READ MORE

  6. 5. How Football Matches Affect Abnormal Returns of European Publicly Traded Football Teams

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Garrett Moberg; Jose Balado; [2020]
    Keywords : Football stocks; Abnormal returns; Event study; Investor sentiment; Business and Economics;

    Abstract : This paper applied a broader, more diverse dataset to investigate whether match results still lead to abnormal returns and to identify which match factors are the most influential. Abnormal returns were measured using the market model and event studies for 23 teams during the 2016-2019 seasons. READ MORE
