  1. 1. Magnetically tunable microwave resonator/filter

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

    Author : Zhi Ye; [2022]
    Keywords : Magnetic tuning; Ferrite; Substrate integrated waveguide resonator; Substrate integrated waveguide filter; Magnetisk inställning; Ferrit; Substratintegrerad vågledarresonator; Substratintegrerad vågledarfilter;

    Abstract : The magnetic tunability of ferrites has been studied and applied on many electric components for working in various frequency bands. Filters or resonators loaded by ferrites can thus work for different frequency requirements by tunning external biasing field. However, filters or resonators built by traditional waveguides are large in size. READ MORE

  3. 2. Improving the safe mode robustness of an Earth observation satellite

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Guillaume Trimoreau; [2022]
    Keywords : avoidance; dazzling; magnetic control; Monte Carlo; safe mode; simulation; tuning; solundvikelsemanöver; solbländning; magnetisk kontroll; Monte Carlo-metoden; säkra läget; simulation; inställning;

    Abstract : Airbus Defence and Space is developing an Earth observation platform. The payload of that platform is an optical instrument, which has to be protected from Sun dazzling in order to preserve its integrity. READ MORE

  4. 3. Brain disease classification using multi-channel 3D convolutional neural networks

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Andreas Christopoulos Charitos; [2021]
    Keywords : Deep Learning DL ; fMRI; CNNs; Tensorflow Keras; ASD; Medical Imaging;

    Abstract : Functional magnetic resonance imaging (fMRI) technology has been used in the investigation of human brain functionality and assist in brain disease diagnosis. While fMRI can be used to model both spatial and temporal brain functionality, the analysis of the fMRI images and the discovery of patterns for certain brain diseases is still a challenging task in medical imaging.

    Abstract : Synchrotron and Free Electron Laser (FEL) light is becoming an increasingly sought after tool for almost all scientific research aspects. MAX IV Laboratory introduced the first 4th generation light source that provides the brightest synchrotron light in the world. READ MORE

  6. 5. Detection of Fat-Water Inversions in MRI Data With Deep Learning Methods

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Lisa Hellgren; Fanny Asketun; [2021]
    Keywords : mr; magnetic resonance; machine learning; deep learning; anomaly detection; U-Net; autoencoder;

    Abstract : Magnetic resonance imaging (MRI) is a widely used medical imaging technique for examinations of the body. However, artifacts are a common problem, that must be handled for reliable diagnoses and to avoid drawing inaccurate conclusions about the contextual insights. READ MORE
