  4. 2. A High Frequency Transformer Winding Model for FRA Applications

    Author : Hanif Tavakoli; Göran Engdahl; Jonas Ekman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; complex permeability; frequency response analysis; time domain reflectometry; high frequency modeling; transformer diagnosis; Electrical engineering; Elektroteknik;

    Abstract : Frequency response analysis (FRA) is a method which is used to detect mechanical faults in transformers. The FRA response of a transformer is determined by its geometry and material properties, and it can be considered as the transformer’s fingerprint. READ MORE

  7. 5. A multi-omics approach to reveal critical mechanisms of activator protein 1 (AP-1) in cancer

    Author : Dandan Song; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Activator protein-1 (AP-1) is a transcriptional factor complex that mainly consists of Fos and Jun family members. Jun proteins can form both homodimers and heterodimers, whereas Fos family members only form heterodimers with the Jun family. Fra-1 is a member of the Fos family proteins and plays a vital role in breast cancer progression. READ MORE
