  1. 1. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Måns Boll; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

  3. 2. Effect of ash on catalytic activity for passive regeneration of catalytic diesel particulate filter : Evaluation of ash deposition by laboratory ageing

    University essay from KTH/Kemiteknik

    Author : Gisela Engström; [2022]
    Keywords : Diesel Particulate Filter; Ash deposition; Laboratory Ageing; Catalytic Activity; Passive regeneration;

    Abstract : Askackumulering i dieselpartikelfilter är ett välkänt problem som resulterar i ett förhöjt mottryck och påverkad prestanda hos fordonet. Däremot ges sällan uppmärksamhet åt filtrets katalytiska aktivitet och hur det påverkas vid förekomst av avgasföroreningar. READ MORE

  4. 3. Screw Joint Analysis in Radio Frequency Filters

    University essay from KTH/Industriell produktion

    Author : Nils Löwhagen; [2022]
    Keywords : Digital filter; Pre-load force; Clamp torque; Release torque; Surface roughness; Thermal shock test; Digitalt filter; Förspänningskraft; Klämvridmoment; Lossdragningsmoment; Ytjämnhet; Termiskt chocktest;

    Abstract : Filter devices are central elements of radio units utilized for modern-day telecommunication. Leakages of radio waves and passive intermodulation are evolving more prominent as the frequency bands become crowded. READ MORE

  5. 4. PLL for 5G mmWave

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Daniel Bakic; Jinzhuo Wu; [2020]
    Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

    Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE

  6. 5. An Autonomous Self-Docking Robot on Passive Systems

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

    Author : Mathieu Gaultier; [2020]
    Keywords : ;

    Abstract : The design of a robot is tightly linked to it assigned task. A robot does not have the same adaptability as humans do. Therefore every robot is designed to achieve one specific task. An increasing alternative to this issue are modular robots. READ MORE
