  1. 6. Estimating patient specific wall shear stress in the human aorta : geometrical and post-processing considerations

    Författare :Johan Renner; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis describes a workflow to perform in-vivo wall shear stress (WSS) estimations in the human aorta using computational fluid dynamics (CFD) methods. An abnormal WSS distribution is believed to influence the development of many cardiovascular diseases, e.g. atherosclerosis. LÄS MER

  3. 7. Ultrawideband-Ultrawidebeam Synthetic Aperture Radar – Signal Processing and Applications

    Författare :Viet Thuy Vu; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This dissertation presents practical issues in Ultrawideband – Ultrawidebeam (UWB) Synthetic Aperture Radar (SAR) signal processing and crucial applications developed on UWB SAR. In the context of this dissertation, UWB SAR refers to the SAR systems utilizing large fractional bandwidth signals and synthesizing long apertures associated with wide antenna beamwidths. LÄS MER

  4. 8. Digital communication in wireline and wireless environments

    Författare :Rickard Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis consists of an introduction and five parts dealing with digital communication. Three parts address Discrete Multi-Tone modulation (DMT), a wireline form of Orthogonal Frequency Division Multiplexing (OFDM). LÄS MER

  5. 9. High speed communication on twisted-pair wires and low complexity multiuser detectors

    Författare :Frank Sjöberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis deals with two different topics: High speed communication on twisted pair wires (digital subscriber lines) and low complexity multiuser detectors. The major part of this thesis concerns a technique for high speed communication over the telephone network called Very high bit rate Digital Subscriber Line VDSL). LÄS MER

  7. 10. Effects of Processing on Dietary Fibre in Vegetables

    Författare :Maria Svanberg; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low molecular weight carbohydrates; carrot cultivars; molecular weight distribution; viscosity; water-soluble polysaccharides; processing; Dietary fibre; vegetables; bulking capacity; rats; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Several beneficial effects have been connected with dietary fibre. Insoluble fibre has a good faecal bulking capacity, whereas soluble and viscous dietary fibre has been shown to have beneficial effects on carbohydrate and lipid metabolism. LÄS MER
