  1. 6. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Fabian Tidner; [2023]
    Nyckelord :Low Frequency stability; DQ-frame modeling; Single phase converter; Electric rail way systems; Lågfrekvent stabilitet; DQ-ram modellering; Enfasig likriktare; Elektriska järnvägssystem;

    Sammanfattning : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. LÄS MER

  3. 7. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Svante Rosenlind; [2023]
    Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER

  4. 8. Exchanging 'Life' for Money? Overtime work culture and professional women's fertility intentions in China

    Master-uppsats, Lunds universitet/Graduate School

    Författare :Jinxuan Lu; [2023]
    Nyckelord :Fertility intention; Overtime work; PLS-SEM; Vignette experiment; Theory of Planned Behavior; Social Sciences;

    Sammanfattning : In the context of China’s concerning decline in fertility rates and the widespread normalization of the ‘996’ overtime culture, the connection between overtime work and fertility assumes considerable importance. This research is firmly grounded in the theoretical framework of the Theory of Planned Behavior (Ajzen, 1991), which investigates the complex relationship between overtime work and fertility intentions among working women of reproductive age in urban China.

  5. 9. Visual Attention Guided Adaptive Quantization for x265 using Deep Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mikaela Gärde; [2023]
    Nyckelord :video encoding; deep learning; visual attention; adaptive quantization; videokodning; djupinlärning; visuellt fokus; adaptiv kvantisering;

    Sammanfattning : The video on demand streaming is raising drastically in popularity, bringing new challenges to the video coding field. There is a need for new video coding techniques that improve performance and reduce the bitrates. LÄS MER

  7. 10. Modeling and Simulation of a Planar Unmanned Aerial Manipulator

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Brynja Þorsteinsdóttir; [2023]
    Nyckelord :Unmanned Aerial Manipulator; Cable Driven Parallel Manipulator; Unmanned Aerial Vehicle; Dynamics; Simulation; Obemannad Flygande Manipulator; Kabeldriven Parallellmanipulator; Obemannad Flygande Farkost; Dynamik; Simulering.;

    Sammanfattning : A unique Unmanned Aerial Manipulator (UAM), also termed an aerial robot, is the subject of this thesis. A UAM is composed of a floating base attached to a manipulator that enables it to interact physically with the environment. LÄS MER
