  1. 11. Taming of the BEAST

    Författare :Maja Loncar; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; tree search; product codes; list distance; list decoding; list-based SISO decoding; ML decoding; MAP decoding; iterative decoding; ISI equalization; BEAST; block codes; Teknik; Signal processing; Signalbehandling;

    Sammanfattning : Modern communication systems are designed to enable reliable and fast information transfer. Therefore, efficient channel coding and decoding strategies are needed, which guarantee sufficiently low probability of erroneous reception with affordable receiver complexity. LÄS MER

  3. 12. Hypnosis monitoring during general anaesthesia : with focus on awareness

    Författare :Andreas Ekman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Hypnosis monitoring; electroencephalogram; BIS; AAI; neuromuscular block;

    Sammanfattning : An objective measure of the hypnotic component of general anaesthesia has been sought for decades. The electroencephalogram (EEG) was early recognized as a possible useful intraoperative monitor when the effects of anaesthetic drugs on human EEG recordings were noted. LÄS MER

  4. 13. Design and Implementation of Embedded Video Surveillance Hardware

    Författare :Fredrik Kristensen; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; image features; tracking; labeling; morphology; real-time operations; Hardware design; Image processing; Imaging; image processing; Bildbehandling; Signal processing; Signalbehandling;

    Sammanfattning : The demands on video surveillance systems are rapidly increasing regarding parameters such as frame rate and resolution. Furthermore, with an ever increasing number of video streams, an automated process for extracting relevant information is required. LÄS MER

  5. 14. Efficient Coding Techniques for Networks & Channels with Transmission Errors

    Författare :Ming Xiao; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channels with Errors; Low-Density Generation-Matrix Codes; Sink Bit Error Probability; Continuous Phase Modulation; Maximum-Likelihood Decoding; Cross-Layer Design; Network Coding; Ring Convolutional Codes; Adaptive Codes.; Deterministic Rateless Codes;

    Sammanfattning : This thesis consists of two parts, both of whichinvestigate coding techniques for information transmission throughchannels in the presence of errors. Part I discusses topics ofnetwork coding and rateless codes. Part~II considers channel codesfor continuous phase modulation. These two parts are clearlydifferent, but they are also related. LÄS MER

  7. 15. The Polyamine Dependence of Cell Cycle Progression-Application in Breast Cancer Treatment

    Författare :Louise Myhre; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tissue culture; histochemistry; Histology; cytochemistry; onkologi; cancer; Cytologi; oncology; cancerology; Cytology; cell cycle kinetics; cell cycle regulatory proteins; polyamine analogues; DENSPM; CGP48664; DFMO; cell cycle regulation; Polyamines; breast cancer; Djurfysiologi; Animal physiology; vävnadskultur; Histologi; cytokemi; histokemi;

    Sammanfattning : In the normal functioning organism, there is a balance between cell proliferation, cell differentiation, and cell death. An imbalance in these processes results in different diseases. This thesis concerns the imbalance where there is too little cell death and cell differentiation with increased cell proliferation.
