  1. 1. Constrained Low-Thrust Satellite Formation-Flying Using Relative Orbit Elements : Autonomous Guidance and Control for the NetSat Satellite Formation-Flying Mission

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

    Author : Lukas Steindorf; [2017]
    Keywords : satellite; formation; control; guidance; continuous; low-thrust;

    Abstract : This thesis proposes a continuous low-thrust guidance and control strategy for satellite formation-flying. Stabilizing feedback based on mean relative orbit elements and Lyapunov theory is used. A novel feedback gain matrix inspired by the fuel-optimal impulsive solution is designed to achieve near-optimal fuel consumption. READ MORE

  2. 2. Simulation of attitude and orbital disturbances acting on ASPECT satellite in the vicinity of the binary asteroid Didymos

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Erick Flores Garcia; [2017]
    Keywords : Solar System; Small celestial bodies; CubeSat; Attitude Determination Control Systems; Orbit Disturbances;

    Abstract : Asteroid missions are gaining interest from the scientific community and many new missions are planned. The Didymos binary asteroid is a Near-Earth Object and the target of the Asteroid Impact and Deflection Assessment (AIDA). READ MORE

  3. 3. Redesign of the interior of the JU solar car

    University essay from Högskolan i Jönköping/JTH, Maskinteknik

    Author : Germán Bielsa; [2017]
    Keywords : Design; User interaction; Ergonomic; Solar car; Steering wheel;

    Abstract : This thesis analyzes the interior of the solar car, used by the JU Solar Team, to improve the user experience in terms of user interaction and ergonomics.Following the Design Thinking methodology, it starts with a research phase to understand how the user interacts with the car and the elements required for this interaction during the race.

  4. 4. Smart Curtain : An Innovative System for Energy Conservation

    University essay from KTH/Maskinkonstruktion (Inst.); KTH/Maskinkonstruktion (Inst.)

    Author : JACOB HÄGGQVIST; ERIK WEDIN; [2016]
    Keywords : ;

    Abstract : The goal of the thesis was constructing a control system for a curtain that would regulate its position between up- and down states depending on out/indoor temperature and incoming solar radiation in order to be more energy efficient. A curtain hanging in front of a window creates a pocket of air, which in tandem with the curtain insulates the window and decreases heat loss, but at the same time it vastly decreases how much solar energy enters the room.

  5. 5. Compression and Shaping of Femtosecond Laser Pulses for Coherent Two-Dimensional Nanoscopy

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

    Author : Lukas Wittenbecher; [2016]
    Keywords : Femtosecond pulse shaping; Ultrafast optics; Liquid crystal spatial light modulator; Coherent two-dimensional nanoscopy; Dispersion compensation; Physics and Astronomy;

    Abstract : Femtosecond pulse shaping is a versatile tool that enables the generation of ultrashort laser pulses with nearly arbitrary temporal shapes. Among others, the technique is of use in ultrafast spectroscopy experiments where it can be employed for dispersion control and the generation of well-defined laser pulse sequences. READ MORE
