  1. 1. Identifying Fundamental Characteristics of Shock Nonstationarity using MMS Measurements : Identifying and Distinguishing Non-stationary Behaviour Through the Magnetic Field Gradient in Quasi-perpendicular Shocks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Hannah Wik; [2023]
    Keywords : Space; Space Plasma Physics; Collisionless Shocks; MMS; Non-stationarity; Shock Reformation; Rippling; Bow Shock; Solar Wind; Rymd; Rymdfysik; Kollisionsfria chocker; MMS; Icke-stationär; Reformation; Bogchock; Solvind;

    Abstract : Collisionless shocks are widespread phenomena in the universe, and understanding the mechanisms behind their energy dissipation, with a rare number of collisions between particles, remains a significant unresolved question. The Earth’s bow shock provides an excellent opportunity to study this phenomena in situ. READ MORE

  3. 2. A simulation-based approach to test the performance of large-scale real time software systems

    University essay from Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Author : Muhammad Waqas; [2020]
    Keywords : Simulation; Machine Learning; Dynamic Modeling; Performance testing of real time systems; Capacity Planning; Simulering; maskininlärning; dynamisk modellering; prestandatestning av realtidssystem; kapacitetsplanering;

    Abstract : Background: A real-time system operates with time constraints, and its correctness depends upon the time on which results are generated. Different industries use different types of real-time systems such as telecommunication, air traffic control systems, generation of power, and spacecraft system. READ MORE

  4. 3. Dynamic Analysis of Sinusoidal, Random and Shock Vibration according to Launch Environment for Small Spacecraft Development to Asteroid 2016-HO3

    University essay from KTH/Lättkonstruktioner

    Author : Akhsanto Anandito; [2019]
    Keywords : spacecraft; resonance frequency; sinusoidal; random vibration; shock; FEM; rymdfarkoster; resonansfrekvens; sinusformad; slumpmässig vibration; chock; FEM;

    Abstract : The investment of space commerce is skyrocketing and it is predicted to be a nascent business in the future. The spacecraft demand has been growing not only for NASA and other space agency’s mission but also collaboration business between small space industries, academia, and scientific community.

  5. 4. Spacecraft dynamic analysis and correlation with test results : Shock environment analysis of LISA Pathfinder at VESTA test bed

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Beata Iwona Kunicka; [2017]
    Keywords : FEA FEM; finite element analysis; finite element method; mechanical analysis; structural analysis; dynamic analysis; computational dynamic analysis of structures; shock analysis; shock environment; shock test; shock test campaign; spacecraft dynamic analysis; MSC Nastran; MSC Patran; Dynaworks; Shock Response Spectrum; SRS; space engineering; space science and technology; mechanical engineering; structural engineering; analysis optimisation; analysis parametrisation; mechanical wave propagation; shock propagation; damping; hysteretic damping; viscous damping; structural damping;

    Abstract : The particular study case in this thesis is the shock test performed on the LISA Pathfinder satellite conducted in a laboratory environment on a dedicated test bed: Vega Shock Test Apparatus (VESTA). This test is considered fully representative to study shock levels produced by fairing jettisoning event at Vega Launcher Vehicle, which induces high shock loads towards the satellite. READ MORE

  6. 5. Calibration and Uncertainty Analysis of a Spacecraft Attitude Determination Test Stand

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Charles Pope; [2017]
    Keywords : Attitude determination; test; error; experiment; analysis; sun sensor; magnetometer;

    Abstract : Experimental testing of attitude determination systems still plays an important role, despite increasing use of simulations. Testing provides a means to numerically quantify system performance, give confidence in the models and methods, and also discover and compensate for unexpected behaviours and interactions with the attitude determination system.
