  1. 1. Characterization of Kelvin Cell Cored Sandwich Structures with Analysis and Experiments

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Sabahattin Bora Günay; [2023]
    Keywords : Kelvin Cell; Sandwich Structure; Space Structures; Three Point Bending Test; Structural Stiffness; Kelvin-cell; smörgåsstruktur; rymdstrukturer; trepunktsböjningstest; strukturell styvhet;

    Abstract : In order to satisfy the mechanical requirements for space structures, achieving lightweight designs is of the greatest significance. The primary focus of this study is the utilization of Kelvin cell core in the design of sandwich structures for space applications. READ MORE

  3. 2. Gradually Changing Gender Attribution of Speech Recordings Using Interpolated Filters

    University essay from Lunds universitet/Matematisk statistik

    Author : Mira Kjellin; [2022]
    Keywords : Mathematics and Statistics;

    Abstract : When we listen to human speech, one of the first characteristics we assess is the gender of the speaker. For individuals who suffer from gender dysphoria, this may cause them to be negatively impacted by their voice not matching their gender identity. Therefore, some persons attempt to change their voices with a speech-language therapist. READ MORE

  4. 3. HVDC transformer core resonance calculation

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Axel Thorstrand; [2021]
    Keywords : HVDC; High Voltage Direct Current; Transformer core; Natural frequencies; Energy method-based equation; HVDC; Högspänning likström; Transformatorkärna; Naturliga frekvenser; Energimetod;

    Abstract : Transformers emit a characteristic humming noise due to magnetostriction which is the continuous change in dimensions during magnetization. The noise is amplified if the induced frequencies match the core’s natural frequencies, consequently avoiding geometries that create resonance is critical in order to fulfill customer sound level requirements.

  5. 4. Analysis of Mouse Whisker Movement Synchronicity

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Johanna Elisabeth de Voogel; [2020]
    Keywords : ;

    Abstract : In active sensing, sensory organs are actively controlled by the motor system to optimize stimuli acquisition. Coupling behaviour of animal models with electrophysiological signals could give us important insights in the workings of this active sensing in health and disease. In this work, a contribution is made towards this aim. READ MORE

  6. 5. Binary classification of HRV signals

    University essay from Lunds universitet/Matematisk statistik

    Author : Rebecca Lütz; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : Heart rate variability, commonly abbreviated as HRV, displays the variance between consecutive heartbeats. This variance occurs naturally but can change due to stress and problems with the cardiac system. HRV is therefore widely used for medical research. READ MORE
