  1. 6. Fabrication and noise properties of high-Tc SQUIDs with multilayer superconducting flux transformers

    Author : Maxim Chukharkin Leonidovich; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; YBCO; High-Tc SQUIDs; SQIFs; ulf-NMR; SQUID magnetometers;

    Abstract : The thesis describes the development of highTc superconducting quantum interference devices (SQUIDs) with multilayer thin film flux transformers. High-Tc SQUID magnetometers are promising in various biomedical applications, including magnetoencephalography (MEG) and ultra-low field magnetic resonance imaging (ulf-MRI). READ MORE

  2. 7. On-scalp MEG using high-Tc SQUIDs: Measuring brain activity with superconducting magnetometers

    Author : Christoph Pfeiffer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-Tc SQUID; neuroimaging; magnetoencephalography; localization; on-scalp MEG; sensor array; magnetometer;

    Abstract : This thesis describes work done towards realizing on-scalp magnetoencephalography (MEG) based on high critical temperature (high- T c) superconducting quantum interference device (SQUID) sensors. MEG is a non-invasive neuroimaging modality that records the magnetic fields produced by neural currents with good spatial and high temporal resolution. READ MORE

  3. 8. Modeling of Magnetic Fields and Extended Objects for Localization Applications

    Author : Niklas Wahlström; Fredrik Gustafsson; Thomas B. Schön; Simon Maskell; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localization; magnetic tracking; extended target tracking; signal processing; machine learning; Gaussian processes; deep dynamical model; discretization;

    Abstract : The level of automation in our society is ever increasing. Technologies like self-driving cars, virtual reality, and fully autonomous robots, which all were unimaginable a few decades ago, are realizable today, and will become standard consumer products in the future. READ MORE

  4. 9. Signal Processing Techniques for Detection of Buried Landmines using Ground Penetrating Radar

    Author : Håkan Brunzell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landmines; detection; feature extraction; impulse radar; ground penetrating radar; classification;

    Abstract : The present thesis deals with the problem of detecting and classifying buried objects. The application in mind when addressing this problem is the detection of buried landmines. According to the International Committee of the Red Cross, about 100 million landmines are buried in 62 countries around the world. READ MORE

  5. 10. Probabilistic modeling for positioning applications using inertial sensors

    Author : Manon Kok; Thomas Schön; Fredrik Gustafsson; Gabriele Bleser; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis, we consider the problem of estimating position and orientation (6D pose) using inertial sensors (accelerometers and gyroscopes). Inertial sensors provide information about the change in position and orientation at high sampling rates. READ MORE
