  2. 21. Fatigue and Fracture of High-Strength Steels : Improving Reliability in Strength Assessment

    Author : Gustav Hultgren; Zuheir Barsoum; Rami Mansour; Torbjörn Narström; Gary Marquis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-Strength Steel; Quality assurance; Probabilistic modeling; Fatigue; Fracture mechanics; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Structural steel plays a fundamental role in the heavy industry, serving as a key material for numerous load-bearing products and equipment. Its widespread use is attributed to its robustness, resistance to wear, ease of use in construction, and cost-effectiveness. READ MORE

  4. 22. Novel Analysis Toolkit for Capillaroscopic Images: Development and Clinical Evaluation

    Author : Abdolamir Karbalaie; Björn-Erik Erlandsson; Olof Lindahl; KTH; []
    Keywords : Nailfold videocapillaroscopy; Image enhancement; Inter and intra-observer reliability; Tillämpad medicinsk teknik; Applied Medical Technology;

    Abstract : Nailfold capillaroscopy (NC) is an invasive imaging technique that is used to assess the blood capillary network in the nailfold area. NC is routinely used for patients with microcirculation problems, such as systemic sclerosis and other connective tissue diseases. NC is repeatable and appears to be simple and harmless. READ MORE

  5. 23. Optimal and Adaptive Subband Beamforming

    Author : Nedelko Grbic; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; Optimal; Adaptive; Speech Enhancement;

    Abstract : The increased use of personal communication devices, personal computers and wireless cellular telephones enables the development of new inter-personal communication systems. The merge between computers and telephony technologies brings up the demand for convenient hands-free communications. READ MORE

  6. 24. Optimizing computed tomography : quality assurance, radiation dose and contrast media

    Author : Patrik Nowik; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Computed tomography (CT) is an important modality in radiology; it enables imaging of the inside of patients without superimposed anatomy. The radiation dose and quality of a CT image are highly dependent on the CT scanner, the scan settings and, if applicable, the timing and dosage of the intravenous contrast media (CM). READ MORE

  7. 25. The Voice Source in Speech Communication - Production and Perception Experiments Involving Inverse Filtering and Synthesis

    Author : Christer Gobl; KTH; []
    Keywords : Voice source dynamics; glottal source parameters; source-filter interaction; voice quality; phonation; perception; affect; emotion; mood; attitude; paralinguistic; inverse filtering; knowledge-based; formant synthesis; LF model; fundamental frequency;

    Abstract : This thesis explores, through a number of production andperception studies, the nature of the voice source signal andhow it varies in spoken communication. Research is alsopresented that deals with the techniques and methodologies foranalysing and synthesising the voice source. READ MORE
