  1. 16. Sensors for intelligent and reliable components

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Pontus Lundman; [2020]
    Keywords : Wind turbine; Gearbox; Sensor; Condition monitoring; Cyber-physical system; Vindkraftverk; Växellåda; Sensor; Tillståndsövervakning; Cyberfysiskt system;

    Abstract : One way to tackle the climate change society is facing today is through the change to renewable energy sources, such as wind power. Today, a trend when it comes to technology is that products are evolving into becoming more cyber-physical systems (CPS) by integrating functions realized with mechanics, control and communication.

  4. 18. Quality Prediction in Jet Printing Using Neural Networks

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Daniel Brun; Colin Lawless; [2020]
    Keywords : ;

    Abstract : Surface mount   technology   is   widely   used   in   the   manufacturing   of   commercial  electronics, and  the  demands  on  the  machines  increase  as  the  complexity of  the electronics increases and the size of the components decreases. Mycronic is a company that focuses on addressing those demands with their high-technology jet printing and pick-and-place machines. READ MORE

  5. 19. 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

  6. 20. 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
