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

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Sophia Holmqvist; [2022]
    Keywords : sarcopenia; microwaves; medical imaging;

    Abstract : 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

    University essay from KTH/Medicinteknik och hälsosystem

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

    Abstract : 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). READ MORE

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

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Holmér; [2021]
    Keywords : ;

    Abstract : 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

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Michelle Dahlman; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 5. Contrast improvement of few-cycle pulses

    University essay from Umeå universitet/Institutionen för fysik

    Author : Xiaoying Zhang; [2019]
    Keywords : ;

    Abstract : The intense few-cycle laser pulses play an important role in the investigations of laser-plasma interaction. However, one of the biggest challenges in their generation is the reduction of temporal intensity contrast by introducing undesired pre-pulses and a long pedestal. Two techniques were investigated in this work to improve the contrast. READ MORE
