  1. 6. Signal Characterization of Atrial Arrhythmias using the Surface ECG

    Författare :Martin Stridh; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; Atrial fibrillation; Atrial arrhythmias; Frequency estimation; Time-frequency analysis; QRST cancellation; ECG;

    Sammanfattning : This doctoral thesis is comprised of five parts which deal with different signal processing problems in ECG-based characterization of atrial arrhythmias. Such characterization requires that the ventricular activity has first been cancelled in the ECG. LÄS MER

  3. 7. Towards a Functional Programming Language for Baseband Signal Processing

    Författare :Anders Persson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; signal processing; domain specific languages; functional programming; code generation;

    Sammanfattning : Developing software for resource constrained embedded systems is a daunting task. In addition to getting the functionality right, a programmer must consider several non-functional properties, including data layout, the target memory hierarchy, concurrency and parallelism. LÄS MER

  4. 8. Mapping Individual Voice Quality over the Voice Range : The Measurement Paradigm of the Voice Range Profile

    Författare :Peter Pabon; Sten Ternström; Maria Södersten; Ingo Titze; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Voice Range Profile VRP ; Phonetogram; Voice Field; Voice quality; Singing voice; Voice synthesis; Clinical voice assessment; Sound level measurement; Maximum Entropy; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : The acoustic signal of voiced sounds has two primary attributes: fundamental frequency and sound level. It has also very many secondary attributes, or ‘voice qualities’, that can be derived from the acoustic signal, in particular from its periodicity and its spectrum. LÄS MER

  5. 9. Membrane and secretory protein production in Escherichia coli

    Författare :Alexandros Karyolaimos; Jan-Willem de Gier; Matthew DeLisa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; recombinant protein; tunable protein production; cytoplasmic membrane; periplasm; signal peptide; force profile analysis; co-translational folding; Biochemistry; biokemi;

    Sammanfattning : Escherichia coli (E. coli) is the most widely used bacterium for the production of recombinant proteins. However, the production of proteins in its cytoplasmic membrane or periplasm is challenging. Therefore, the aim of this doctoral thesis was to develop setups for enhancing the production of membrane and secretory proteins in E. LÄS MER

  7. 10. Extracting 3D Information from 2D Crooked Line Seismic Data on Hardrock Environments

    Författare :Johiris Isabel Rodriguez Tablante; Christopher Juhlin; Pekka Heikkinen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Hardrock Environment; Crooked line; Reflection Seismics; signal-to-noise; cross-dip; cross-profile; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : Seismic methods have been used in sedimentary environment for almost 80 years. During that time, exploration geophysicists have developed a number of techniques to handle specific aspects of working in sedimentary areas. LÄS MER
