  1. 1. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Joel Johansson Byberg; [2019]
    Keywords : CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

    Abstract : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.

  2. 2. PPS5000 Thruster Emulator Architecture Development & Hardware Design

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Robert Persson; [2019]
    Keywords : Electric Propulsion; Spacecraft; Ground Support Equipment; OHB Sweden; Emulator; Thruster; Elektrisk Framdrivning; Rymdfarkost; Markutrustning; Testutrustning;

    Abstract : This Master's Thesis handles prestudy work and early hardware development that resulted in architectural definitions and prototype hardware of electronic ground support equipment. This equipment is destined to emulate the electric power consumption of the PPS5000 Hall Effect Thruster (HET), for use in satellite end-to-end tests of the all-electric Geostationary Satellite Electra, developed at OHB Sweden AB.

  3. 3. Decoding Electrocorticography Signals by Deep Learning for Brain-Computer Interface

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Guillaume JUBIEN; [2019]
    Keywords : Deep learning; BCI; ECoG; Spatial filtering;

    Abstract : Brain-Computer Interface (BCI) offers the opportunity to paralyzed patients to control their movements without any neuromuscular activity. Signal processing of neuronal activity enables to decode movement intentions. Ability for patient to control an effector is closely linked to this decoding performance. READ MORE

  4. 4. AP&T Machine and Line Usability : A usability analysis of stand-alone machines and production lines at AP&T

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Fanny Åkerström; [2019]
    Keywords : Usability; user experience; user needs; human-machine interaction; press hardening; industry; digitalization; automation; production solution; development; Användarvänlighet; användarupplevelse; användarbehov; HMI; presshärdning; industri; digitalisering; automation; produktionslösning; utveckling;

    Abstract : Automation and digitalization are developing at a high pace and it is important to keep the focus on human-machine interaction. It is becoming more and more important that the usability in machines and lines is related to the development so that the performance and availability of the production processes in the industry are not adversely affected.
