  1. 1. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Abhiroop Chatterjee; [2023]
    Nyckelord :;

    Sammanfattning : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. LÄS MER

  3. 2. osimetric impact of system spe cific geometric distortion on head and neck treatment plans in MRI only based radiation therapy

    Master-uppsats,

    Författare :Jesper Brovall; [2022-01-13]
    Nyckelord :Medical physics; Dosimetry; MRI; Radiation therapy;

    Sammanfattning : Background/ purpose: Because of the superior soft tissue contrast, in comparison with computed tomography (CT) data, magnetic resonance imaging (MRI) is of high interest to include in a larger extent in the ra diation therapy (RT) process. In an MRI only workflow, the CT scan is excluded and a synthetic CT is used for treatment plan ning. LÄS MER

  4. 3. Gryningen nalkas : En komparativ studie av Johannes av Korsets och Hartmut Rosas förståelse av vägen mot ett gott förhållande till världen

    Kandidat-uppsats, Uppsala universitet/Teologiska institutionen

    Författare :Joel Wanemark; [2022]
    Nyckelord :Hartmut Rosa; Johannes av Korset; resonans; mystik;

    Sammanfattning : This study presents a comparative analysis of Hartmut Rosa and St John of the Cross and their respective view of the way towards a good relationship to the world. Using Rosa’s theory of acceleration, alienation and resonance as a frame of reference, a discursive analysis of modern texts on the thoughts of St John is performed to explore how the thoughts of St John can be enriched by Rosa.

  5. 4. "Resonance frequency, Q-factor, coupling of a cylindrical cavity and the effect on graphite from an alternating electric field".

    Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Jakob Gölén; Simon Persson; [2021]
    Nyckelord :Q-factor; Resonance frequency; Cavity; Microwaves; Heating; Q-faktor; Resonansfrekvens; Kavitet; Mikrovågor; Uppvärmning;

    Sammanfattning : The purpose of this project was to investigate a cylindrical cavity resonator and use microwaves to heat up a material in the cavity. This was done by measuring the Q-factor and the resonance frequency of the cavity, both with and without material inside. LÄS MER

  7. 5. Comparative Study of Vision Camera-based Vibration Analysis with the Laser Vibrometer Method

    Master-uppsats, KTH/Industriell produktion

    Författare :Pradeep Kumar Muralidharan; Hemanth Yanamadala; [2021]
    Nyckelord :OpenCV; Motion tracking; motion magnification; vision camera method; FFT; tracker; OpenCV; Rörelsesspårning; Rörelseförstoring; Synkamera -metod; FFT; Spårare;

    Sammanfattning : Vibration analysis is a method that studies patterns in vibration data and measures vibration levels. It is usually performed on time waveforms of the vibration signal directly and on thefrequency spectrum derived by applying the Fourier Transform on the time waveform. LÄS MER
