  3. 17. On Soft Decoding and Robust Vector Quantization

    Författare :Mikael Skoglund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech and image coding; intersymbol interference; Rayleigh fading; soft decoding; CDMA; index assignment; Hadamard transform; channel optimized VQ; robust VQ; combined source-channel coding; vector quantization VQ ; noisy channels;

    Sammanfattning : This thesis considers vector quantization for noisy channels. Vector quantization (VQ) is an important technique for block-based source coding, with applications in, e.g., speech and image coding. LÄS MER

  4. 18. Genetic re-targeting and de-targeting of adenovirus type 5 in order to create vectors for gene therapy

    Författare :Susanna Myhre; Göteborgs universitet; []
    Nyckelord :Adenovirus; gene therapy; vector; re-targeting; de-targeting; fiber; pIX; affibody molecule; single chain antibody;

    Sammanfattning : Gene therapy has been considered to be a revolutionary development in medicine, whereby the cause and not the symptoms of the disease would be treated. These expectations have as yet not been realized, mainly due to lack of suitable vectors. LÄS MER

  5. 19. Characterisation of Urban Rainfall in Kuala Lumpur, Malaysia

    Författare :Mohamed Nor bin Desa Mohamed; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; velocity; vector; monsoon; Malaysia; thunderstorm; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : Rainfall characteristics of Kuala Lumpur, Malaysia, are studied in space and time; on a large scale, 550 km2, and long term scale to find out the monsoon influence, and on urban basin scale, 23 km2, to determine dynamic properties of rainfalls and spatial correlations, and on a point scale to determine the probabilities of very high rain intensities. The importance of spatial and temporal variability of rainfall was investigated applying cross correlation on long term historical rainfalls from Kuala Lumpur, Malaysia. LÄS MER

  7. 20. Retargeting of adenovirus vectors. Viral ligands and cellular receptors

    Författare :Petra Henning; Göteborgs universitet; []
    Nyckelord :Adenovirus; vector; gene therapy; gene transfer; retargeting; detargeting; tumor targeting; fiber; pIX; affibody molecule; single chain antibody;

    Sammanfattning : Gene therapy is one of the newest technologies attempted to treat human cancer. Progress in the field has however been hampered by the lack of efficient and safe vectors. Ideal vectors should specifically transduce desired cells in vivo. This thesis is devoted to the development and evaluation of retargeted adenovirus type 5 (Ad5) vectors. LÄS MER
