  1. 16. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications

    University essay from KTH/Tillämpad fysik

    Author : Wilhelm Holmberg; [2023]
    Keywords : High Electron Mobility Transistor; HEMT; Gallium Nitride; GaN; Silicon Carbide; SiC; Proton Radiation; Galliumnitrid; GaN; Kiselkarbid; SiC; Kisel; Si; HEMT; Transistor; Protonstrålning;

    Abstract : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. READ MORE

  3. 17. Phase Noise Performance of a PLL Frequency Synthesizer when Powered by Silent Switchers

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

    Author : Sampriti Basu; [2023]
    Keywords : Silent Switcher; PLL synthesizer; Phase noise; PCB implementation.; Silent Switcher; PLL-synthesizer; fasbrus; PCB-implementering.;

    Abstract : In use today are ‘normal’ DC-DC switching regulators with considerable switching noise and ringing, which is bad for noise-sensitive applications. This project involves a solution based on ‘Silent Switchers’ to prove its effectiveness in reducing noise. READ MORE

  4. 18. Turning off the lights or changing the lamps? : Evaluation of the electricity use at Uppsala University Hospital

    University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Author : Maya Linder; Julia Malmås; Sofia Näslund; Matilda Sojé; [2023]
    Keywords : ;

    Abstract : This bachelor thesis will examine the actions that have been taken to lower the electricity use at Uppsala University Hospital during the winter of 2022/2023. To be able to evaluate the changes that have been done there will be a comparison between the winter of 2022/2023 and the winter of 2021/2022. READ MORE

  5. 19. “People seem to understand numbers better than the alphabet” : Experiences and effects of reclassification from SAB to Dewey at a university library

    University essay from Lunds universitet/Avdelningen för ABM, digitala kulturer samt förlags- och bokmarknadskunskap

    Author : Julia Ptasznik; [2023]
    Keywords : Library; Information; Knowledge Organization; Classification Systems; SAB; Dewey Decimal Classification; DDC; DDK; Infrastructure; Infrastructure Theory; Cultural Sciences;

    Abstract : This thesis is an analysis of the effects and experiences of reclassification from the Swedish SAB system to the Dewey Decimal Classification at one of the faculty libraries at Lund University. The background for this study is the National Library report from 2006 where advantages and disadvantages of switching to the DDC were outlined. READ MORE

  6. 20. Mobile Traffic Classification and Multi-Cell Base Station Control for Energy-Efficient 5G Networks

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

    Author : Cai Tianzhang; [2023]
    Keywords : ;

    Abstract : The global energy consumption of mobile networks is rapidly increasing due to the exponential growth of mobile network traffic. The advent of next-generation cellular technologies such as fifth-generation (5G) and beyond promises higher network throughput and lower latency but also demands higher power consumption for its denser base station (BS) deployment and more energy-intensive processors.
