  1. 1. 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

  2. 2. 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

  3. 3. 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

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

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

    Author : Qiao Jin; [2022]
    Keywords : Embedded systems; ESP 32; Cryptographic algorithms; Cryptographic hardware acceleration; AES; RSA; SHA-2; HTTPS; Inbyggda system; ESP 32; Kryptografiska algoritmer; Kryptografisk hårdvaruacceleration; AES; RSA; SHA-2; HTTPS;

    Abstract : The rise of the Internet of Things (IoT) and autonomous robots/vehicles comes with a lot of embedded electronic systems. Small printed circuit boards with microcomputers will be embedded almost everywhere. READ MORE

  5. 5. Design of 3D-Printed Components : Resistances, Strain Gauges and Touch sensors

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

    Author : Joar Forsberg; [2022]
    Keywords : 3D-printing; FFF; Conductive PLA; Strain Gauge; Touch sensor; 3D-printing; FFF; Konduktiv PLA; Töjningsgivare; Vidröringssensor;

    Abstract : Additive manufacturing has recently become an increasingly available, affordable, and versatile technology for industry and enthusiasts alike. One opportunity that this provides is using conductive filament to print electronic sensors and components. READ MORE
