  1. 6. Life-Cycle Assessment of Humidity Sensors printed with Forest-based Ink and Laser Graphitization

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

    Author : Rumpee Bora; [2023]
    Keywords : Life Cycle Assessment; Printed Electronics; Laser Graphitization; Flexible Humidity Sensor; Wood Ink; Livscykelanalys; Tryckt Elektronik; Lasergrafitisering; Flexibel Fuktighetssensor; Träbläck;

    Abstract : The increasing demand for digitalization has spurred the need for novel and sustainable designs of electronic devices like sensors. Advanced additive print technologies, organic inks, and bio-based substrates in device fabrication exhibit promising potential for reducing energy and raw material consumption, thereby alleviating environmental impacts.

  3. 7. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

    University essay from Linköpings universitet/Fordonssystem

    Author : Gabriel Fredriksson; [2022]
    Keywords : machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

    Abstract : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. READ MORE

  4. 8. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    University essay from KTH/Tillämpad fysik

    Author : Marie Defives; [2022]
    Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE

  5. 9. Conceptual design of an electronic dockingstation and positioner for portable antenna

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Otto Egeman; Karl Westling; [2022]
    Keywords : Antenna; Automatic positioner; Geostationary; Docking station; Antenn; Automatisk inpekning; Geostationär; Dockningsstation;

    Abstract : The presented work in this report is a master’s thesis at the machine design track at KTH Royal Institute of Technology. The work was commissioned by Ovzon through Svea Teknik AB. The T6 antenna in Ovzons antenna terminal portfolio is as of now fully manual in terms of positioning against satellites. READ MORE

  6. 10. Performance Evaluation of Cryptographic Algorithms on ESP32 with Cryptographic Hardware Acceleration Feature

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