  2. 1. The role of microstructure for crack propagation in cortical bone

    Author : Anna Gustafsson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crack deflection; Interface; Mechanical testing; Micro-CT; Osteon; Porosity; XFEM;

    Abstract : Healthy cortical bone tissue is both tough and strong and has a unique ability to resist fracture. One reason is the hierarchical structure of the tissue where toughening mechanisms at all length scales act to slow down or stop a propagating crack. READ MORE

  4. 2. Computational Diffusion MRI: Optimal Gradient Encoding Schemes

    Author : Mohammad Alipoor; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gradient Encoding Scheme; ADC imaging; Diffusion MRI; D-optimal experiment design; Diffusion Tensor Imaging; Optimal Image acquisition; Second and Fourth Order Tensors.; Diffusion Kurtosis Imaging;

    Abstract : Diffusion-weighted magnetic resonance imaging (dMRI) is a non-invasivestructural imaging technique that provides information about tissue microstructures.Quantitative measures derived from dMRI reflect pathologicaland developmental changes in living tissues such as human brain.

  5. 3. Soft Tissue Mechanics with Emphasis on Residual Stress Modeling

    Author : Tobias Olsson; Anders Klarbring; Ray W. Ogden; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanics; Residual Stress; Growth; Remodeling; Engineering mechanics; Teknisk mekanik;

    Abstract : This thesis concerns residual stress modeling in soft living tissues. The word living means that the tissue interacts with surrounding organs and that it can change its internal properties to optimize its function. READ MORE

  6. 4. Circuit Design Techniques for Implantable Closed-Loop Neural Interfaces

    Author : Nikola Ivanisevic; Ana Rusu; Saul Rodriguez; Angel Rodriguez Vazquez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural interface; ECoG; high-resolution; ADC; recording; delta-sigma modulator; system identification; impedance measurements; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Implantable neural interfaces are microelectronic systems, which have the potential to enable a wide range of applications, such as diagnosis and treatment of neurological disorders. These applications depend on neural interfaces to accurately record electrical activity from the surface of the brain, referred to as electrocorticography (ECoG), and provide controlled electrical stimulation as feedback.

  7. 5. In Vivo Diffuse Reflectance Spectroscopy of Human Tissue : From Point Measurements to Imaging

    Author : Erik Häggblad; Göran Salerud; Tomas Strömberg; Maurice C. G. Maurice C. G. Aalders; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical engineering; Medicinsk teknik;

    Abstract : This thesis presents the non-invasive use of diffuse reflectance spectroscopy (DRS) to provide information about the biochemical composition of living tissue. During DRS measurements, the incident, visible light is partially absorbed by chromophores but also scattered in the tissue before being remitted. READ MORE
