  1. 1. Test and Calibration of CUBES: a CubeSat X-ray Detector

    University essay from KTH/Fysik

    Author : Caroline Holmberg; [2022]
    Keywords : Applied Physics; Astroparticle Physics; Tillämpad fysik; Astropartikelfysik;

    Abstract : CUBES is an X-ray detector that will be placed aboard the KTH 3U CubeSat mission, MIST. Its purpose is to detect high energy X-rays as well as to test various components in a space environment. Two CUBES will be placed on the satellite. Each CUBES consists of a printed circuit board (PCB) with three multi pixel photon counters (MPPCs). READ MORE

  2. 2. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : David Aronsson Edström; Oskar Lundberg; [2022]
    Keywords : 3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

    Abstract : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. READ MORE

  3. 3. Design and evaluation of a solid-state LiDAR system : for wireless distance measurements

    University essay from Uppsala universitet/Signaler och system

    Author : Christian Hagstedt; Sebastian Jönsson; [2022]
    Keywords : Solid-state; LiDAR; Python; Raspberry Pi; Switching regulator; PCB; 3D Printing;

    Abstract : The advent of smarter vehicles coupled with declining costs for solid-state light detection and ranging (LiDAR) sensors unlocks the potential of cheaper devices that experience less mechanical wear while providing smaller form factors. The early state of the market makes evaluating the limited supply of available sensors interesting. READ MORE

  4. 4. Application demonstrator for green IoT unit including Ligna S-power

    University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Author : Arvid Bläser; [2022]
    Keywords : Ligna; Energy; IoT; Battery; Printed; Electronics; Harvester; LoRa; LoRaWAN;

    Abstract : Ligna Energy has developed a printable battery, called S-Power. It is based on research in organic electronics. In order to demonstrate the functionality of the new batteries, an IoT device was developed. The demonstrator consisted of a Sensor for temperature and relative humidity (RH), LoRWAN communication and a circuit for energy harvesting. READ MORE

  5. 5. 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
