  1. 1. Dataset based on volunteer campaign to optimize novel sensor for muscle quality

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Sophia Holmqvist; [2022]
    Nyckelord :sarcopenia; microwaves; medical imaging;

    Sammanfattning : This project had its primary focus on running a campaign to recruit healthy volunteers for a test study involving the utilization of a microwave sensor and ultrasound measurements. The key system used was the Muscle Analyzer System (MAS), which consisted of the Bandstop Filter Sensor (BFS), a microwave sensor transmitting microwaves into the selected medium through transmission and a FieldFox Vector Network Analyzer which was used to transmit these microwaves.

  3. 2. Evaluation of the Impact of X-ray Tube Voltage and Filter Thickness on the Performance of Spectral Photon-Counting Detectors

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Cassandra Mannila; Marcus Larsson; [2021]
    Nyckelord :Photon Counting Detectors; X-ray Tube Voltage; Filter Thickness; Detective Quantum Efficiency; Optimizing; Fotonräknande detektorer; Rörspänning; Filtertjocklek; DQE; Optimering;

    Sammanfattning : During the past years photon-counting detectors (PCDs) have emerged as an alternative to conventional energy-integrating detectors and may significantly improve the standard of care for computed tomography (CT). There are two main alternatives for the material of the detector: cadmium telluride (CdTe) and silicon (Si). LÄS MER

  4. 3. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Sara Holmér; [2021]
    Nyckelord :;

    Sammanfattning : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

  5. 4. Implementation of the mille-feuille nanofilter paper in the virus removal filtration of IgY purified from chicken egg yolk

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Michelle Dahlman; [2020]
    Nyckelord :;

    Sammanfattning : The purpose of this thesis was to test the mille-feuille nanofilter paper for a virus removal filtration from a potential protein-based nutraceutical. Therefore, chicken IgY was purified from egg yolk, with PEG precipitation for crude fractionation followed by thiophilic adsorption chromatography. LÄS MER

  7. 5. Dimensionering av filterbehållare till luftreningssystem

    M1-uppsats, KTH/Hållbar produktionsutveckling (ML)

    Författare :Elif Kahruman; [2020]
    Nyckelord :;

    Sammanfattning : Målet med examensarbetet är att leverera dimensioneringsunderlag för konstruktion av filterbehållaren som används i luftreningssystemet hos företaget Centriair AB. Dimensioneringen utföres genom användande av analytisk, numerisk och finitelements beräkning med hänsyn till hållfasthet och deformationer. LÄS MER
