  1. 6. Characterizing coil windings noise due to compressive fault currents : A study to determine if there is a characteristic noise from transformer windings due to fault currents

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Lundgren; [2022]
    Keywords : Transformer windings; short circuit forces; current pulses; microphone; Comsol Multiphysics; FFT; Transformator lindningar; strömpulser; mikrofon; kortslutingskrafter; Comsol Multiphysics; FFT;

    Abstract : Transformers are essential for modern power distribution system. They are efficient and enable the voltages to be transformed up for transportation of electricity and back down for consumer use. The reliability of the transformer is affected by faults and fatigue of the copper. READ MORE

  3. 7. Effect of doxorubicin exposure in breast cancer on single-cell level by scRNA-seq analysis

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Núria Lladós Armengol; [2021]
    Keywords : ;

    Abstract : Doxorubicin is a highly effective chemotherapeutic agent against a variety of cancers; however, the exact mechanisms responsible for the effects of doxorubicin on cancer are not widely understood and have not been studied on a single-cell level. Single-cell RNA sequencing analysis is a recent technology that enables the assessment of transcriptional similarities and differences within a population of cells. READ MORE
