  1. 21. Properties of the Optical Hot Spots in the Circumstellar Ring of SN 1987A

    University essay from KTH/Fysik

    Author : Christos Tegkelidis; [2023]
    Keywords : ;

    Abstract : The proximity of Supernova 1987A provides a great opportunity to study the aftermath of the impact of the ejecta with the dense clumps (observed as ”hot spots”) located in the equatorial circumstellar ring. This thesis examines the properties of the clumps by using Hubble Space Telescope optical imaging taken with the F625W and F675W broad filters between 1994 and 2022. READ MORE

  2. 22. Developing an Ar milling process to improve the contact quality to InAs nanowires

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

    Author : Chris Mkolongo; [2023]
    Keywords : InAs nanowires; Argon milling; Technology and Engineering;

    Abstract : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). READ MORE

  4. 24. State of charge and heat impact on Li-ion batteries during calendar aging

    University essay from Uppsala universitet/Signaler och system

    Author : Martin Jonsson; Tobias Karlsson; [2023]
    Keywords : State of charge; SoC; calendar aging; heat impact; Li-ion;

    Abstract : Rechargeable batteries that are powering our everyday electronics go through their lifetime with countless charge/discharge cycles, after a few years the capacity has dropped noticeably. But how about batteries that are working as a back-up power system for when connection to the AC mains is not possible, they might only perform a handful of cycles but does this mean they last forever? On behalf of Getinge AB, this bachelor thesis aims to explore the subject named as ‘calendar aging’. READ MORE

  5. 25. Smartphone Sensor Data for Physical Activity Monitoring and Analysis

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

    Author : Ivy Liu; Sebastian Hinze; [2023]
    Keywords : ;

    Abstract : As awareness of health risks associated with a sedentary lifestyle is raised, the demands fortechnological tools to help track one’s physical activity levels grow as well. A technologicalconcept that could be used to aid in this issue is human activity recognition (HAR), whichmaps signal data to recognisable human activity. READ MORE
