1. 1. Electrohydraulic Power Steering Simulation : Dynamic, thermal and hydraulic modelling

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

   Author : Oskar Svensson; [2019]
   Keywords : PMSM; SVPWM; vector control; FOC; lumped parameter model; LPM; hydraulic pump; simulation;

   Abstract : There are several benets of electrohydraulic power steering systems, as compared to hydraulicpower steering systems where the pump is driven directly by the engine of the vehicle. Someof these benets are increased eciency and improved steering performance. READ MORE

3. 2. Passivation of Gallium Arsenide Nanowires for Solar Cells

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Austin Irish; [2019]
   Keywords : nanowires; semiconductors; solar cells; photovoltaics; passivation; electronics; chemistry; polymers; hydrazine; plasma; gallium; arsenic; iii-v; epitaxy; photoluminescence; time-resolved; spectroscopy; Physics and Astronomy;

   Abstract : A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. READ MORE

4. 3. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

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

   Author : Vidar Flodgren; [2019]
   Keywords : GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

   Abstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE

5. 4. Development of an Automated Test Platform for Characterization and Performance Assessment of Electronic Modules in Electric Thrusters : The TESPEMET Project

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Sri Harsha Pavuluri; [2019]
   Keywords : rf ion thruster; electric thruster; automated test; micropython; test platform;

   Abstract : There has been a sharp increase in the market for electric propulsion systems for small satellites in the recent years. Electric propulsion systems have become smaller, more efficient and cheaper, which made them ideal for small satellites because they have a low thrust requirement and benefit significantly from the high specific impulse (Isp) that is characteristic to electric thrusters.

6. 5. 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.
