  4. 8. Quantification of Fat Content and Fatty Acid Composition Using Magnetic Resonance Imaging

    Författare :Pernilla Peterson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; fat quantification; water fat imaging; chemical shift; skeletal muscle; fat reference; bipolar gradient; fatty acid composition; relaxation;

    Sammanfattning : In obesity and several other disease scenarios, the measurement of fat accumulation in various organs and tissues has become a sought-after technique in clinical diagnostics and research. Especially, quantitative and non-invasive techniques which also provide images of accumulated fat throughout the body would be valuable. LÄS MER

  5. 9. Multivariate Data Analytics to Identify Driver’s Sleepiness, Cognitive load, and Stress

    Författare :Shaibal Barua; Shahina Begum; Peter Funk; Mobyen Uddin Ahmed; Christer Ahlström; Nirmalie Wiratunga; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Driver monitoring; Driver state; Physiological signals; Machine learning; Contextual information; Computer Science; datavetenskap;

    Sammanfattning : Driving a vehicle in a dynamic traffic environment requires continuous adaptation of a complex manifold of physiological and cognitive activities. Impaired driving due to, for example, sleepiness, inattention, cognitive load or stress, affects one’s ability to adapt, predict and react to upcoming traffic events. LÄS MER

  7. 10. On Modulation and Detection Schemes for Low-Complexity Impulse Radio UWB Communications

    Författare :Muhammad Gufran Khan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB; RAKE; Transmitted reference; Energy detection; Channel measurements; BPPM;

    Sammanfattning : Due to wealth of advantages offered by short range ultra wideband (UWB) technology, such as capacity improvement, fading reduction and localization, it has gathered a considerable attention. Distinct UWB qualities also pose many system design challenges like difficulties in using digital processing, complex channel estimation and different propagation characteristics. LÄS MER
