  1. 1. Techniques to inject pulsating momentum

    University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanik

    Author : Jelle Kranenbarg; [2020]
    Keywords : Hydro power; Rotating Vortex Rope; Flow control; Fluidic actuator; Synthetic jet actuator; Piston actuator; CFD;

    Abstract : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. READ MORE

  2. 2. Digital Compensation of Phase Noise Caused by Mechanical Vibrations

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Akib Mahmud; [2019]
    Keywords : ;

    Abstract : The component that generates the frequency of the radio waves transmitted by a radar is generally built around a quartz crystal oscillator. When this component is exposed to mechanical vibrations, such as acceleration or rotation in different directions, phase noise occurs. READ MORE

  3. 3. Automotive Energy Harvesting

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Petter Haugen; [2019]
    Keywords : Vibration measurement; Energy Harvesting; Piezoelectrics; On-Board Unit;

    Abstract : Vibration measurements conducted in three vehicles windshields are used to determine frequency content in the windshield of moving vehicles. A piezoelectric energy harvester is modeled, and used in simulations to determine output voltage and power with measured acceleration signal as input.  .. READ MORE

  5. 5. Fabrication and characterisation of RGB LEDs based on nanowire technology

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

    Author : Patrik Olausson; [2019]
    Keywords : RGB LEDs; InGaN; GaN; nitrides; platelets; nanotechnology; Technology and Engineering;

    Abstract : The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. READ MORE
