  1. 1. Determinants and influence of mammographic features on breast cancer risk

    Författare :Shadi Azam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mammographic density and mammographic microcalcifications are the key imaging features in mammography examination. Mammographic density is known as a strong risk factor for breast cancer and is the radiographic appearance of epithelial and fibrous tissue which appears white on a mammogram. LÄS MER

  3. 2. Artificial Intelligence-Based Characterization and Classification Methods for Power Quality Data Analytics

    Författare :Azam Bagheri; Math Bollen; Surya Santoso; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power System; power Quality; Voltage Dip; Big Data; Deep Learning; Machine Learning; Active Learning; Consensus Contriol; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : One of the important developments in the electric power system is the fast increasing amount of data. An example of such data is formed by the voltages and currents coming from power-quality measurements. LÄS MER

  4. 3. Extracting Information from Voltage-Dip Monitoring

    Författare :Azam Bagheri; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : A voltage dip is a short duration reduction in voltage magnitude due to a short duration increase in current magnitude. Causes of dips are, among others, electrical faults, large motor starting, transformer energizing and failure of power-electronic converters. LÄS MER

  5. 4. Produktivitetsmätningar som förbättringsverktyg : en kartläggning av arbetsproduktivitetsmätningar på svenska byggarbetsplatser

    Författare :Azam Forsberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : The Swedish construction industry has over the last few years been criticized for its high increase of production costs, poor quality and low productivity. Productivity improvements within the Swedish construction industries are lower than that of other comparable industries. LÄS MER

  7. 5. Waste Textiles Bioprocessing to Ethanol and Biogas

    Författare :Azam Jeihanipour; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery;

    Sammanfattning : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. LÄS MER
