  1. 1. Algorithm-Architecture Co-Design for Digital Front-Ends in Mobile Receivers

    Författare :Isael Diaz; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture Optimization; Digital Front End; Wireless Communication; Mobile terminal;

    Sammanfattning : The methodology behind this work has been to use the concept of algorithm-hardware co-design to achieve efficient solutions related to the digital front-end in mobile receivers. It has been shown that, by looking at algorithms and hardware architectures together, more efficient solutions can be found; i.e. LÄS MER

  3. 2. Hyperpolarized 3He-diffusion MRI in evaluation of lung structure in emphysema. Validation and development of the method

    Författare :Sandra Diaz; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helium; Hyperpolarized; MRI; ADC; Emphysema;

    Sammanfattning : Abstract COPD is a major cause of chronic morbidity and mortality throughout the world. It is a preventable and treatable disease. Smoking is the most commonly encountered risk factor for COPD and the habit now unfortunately starts at earlier ages than before. LÄS MER

  4. 3. Biogas from slaughterhouse waste : Mixtures interactions in co-digestion

    Författare :Jhosané Pagés Diaz; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slaughterhouse waste; Agro-Waste; Co-digestion; Synergistic effects; Methanogenic community structure; Resource Recovery; Resursåtervinning;

    Sammanfattning : Global environmental concerns connected to the use of fossil fuels have forced the development ofalternative sustainable energy technologies. The application of anaerobic digestion, from waste streams thatcurrently have no use, can be utilized for bioenergy production. LÄS MER

  5. 4. Numerical modelling of positive electrical discharges in long air gaps

    Författare :Oscar Diaz; Vernon Cooray; Raul Montano; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high voltage techniques; numerical modeling; electrical discharge in gases; streamer mechanism; leader channel; Engineering Science with specialization in Atmospheric Discharges; Teknisk fysik med inriktning mot atmosfäriska urladdningar;

    Sammanfattning : This dissertation deals with research on the numerical modelling of electrical discharges in laboratory long air gaps excited with positive switching impulses. It begins with the preliminary work of several scientists during the last decades, making a detailed analysis of different approaches for modelling all the stages in a full discharge. LÄS MER

  7. 5. A UDP-glucose deficient mutant cell line as a model to study the cytotoxicity of Clostridium perfringens PLC

    Författare :Marietta Flores Diaz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A Chinese Hamster fibroblast mutant cell line, deficient in UDP-glucose (UDP-Glc) and hypersensitive to Clostridium perfringens phospholipase C (PLC) was used in this study to determine some of the molecular consequences of a cellular UDP-Glc deficiency. Furthermore, using this cell as a model, structure/function studies were performed to identify residues critical for the cytotoxic activity of PLC. LÄS MER
