  1. 11. Component-Based Transfer Path Analysis and Hybrid Substructuring at high frequencies : A treatise on error modelling in Transfer Path Analysis

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Harikrishnan Venugopal; [2020]
    Nyckelord :Dynamic Substructuring; Error modelling; Transfer Path Analysis; Uncertainty Propagation; Dynamisk substrukturering; Feluppskattning; Överföringsanalys; Osäkerhetspropagering;

    Sammanfattning : The field of modal testing and analysis is currently facing a surge of interest in error modelling. Several errors which occur during testing campaigns are modelled analytically or numerically and propagated to various system coupling and interface reduction routines effectively. LÄS MER

  2. 12. B-plane orbital resonance analysis and applications

    Master-uppsats, KTH/Rymdteknik

    Författare :Alessandro Masat; [2020]
    Nyckelord :;

    Sammanfattning : Many space engineering and orbital mechanics applications seek for the usage of focused mathematical models, capable of providing useful insight onto particular phenomena or exploiting some theoretical and physical tools to reduce the computational costs and/or increase the level of accuracy reached. Orbital resonances are one of the phenomena that needs to be properly modelled, both for exploiting such features in the mission design phase and to predict possible resonant returns of threatening objects closely approaching a specified planet.

  3. 13. Forensic Validation of 3D models

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Mimmi Lindberg; [2020]
    Nyckelord :sfm; structure from motion; 3d reconstruction; uncertainty; uncertainty propagation; 3d models;

    Sammanfattning : 3D reconstruction can be used in forensic science to reconstruct crime scenes and objects so that measurements and further information can be acquired off-site. It is desirable to use image based reconstruction methods but there is currently no procedure available for determining the uncertainty of such reconstructions. LÄS MER

  4. 14. Reflected Train Noise in Swedish Noise Prediction Methods, a comparison between measurements, Nordic Prediction Method, Nord2000 rail and CNOSSOS

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Ka Hou Karl Ho; [2020]
    Nyckelord :Nord2000; NMT; Noise prediction method; sound propagation model; source model for railway noise; reflected sound; Nord2000; nordiska beräkningsmodellen för tågbuller; bullerberäkningsmodell; Ljudutbredningen modellen for tåg buller; källsmodell för tåg buller; fasadreflektioner;

    Sammanfattning : The Swedish law requires a set of noise limit for residential buildings for health and safety. Conventionally, the Nordic Prediction Method (NMT) is used to predict the noise. However Nord2000 and CNOSSOS is going to be introduced to replace NMT. LÄS MER

  5. 15. A Simulation of Landslide-Generated Waves Using a Fully Implicit ISPH

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Kosei Nishida; [2020]
    Nyckelord :SPH; Landslide-generated waves; non-newtonian fluid; multiphase flow; Technology and Engineering;

    Sammanfattning : Smoothed Particle Hydrodynamics (SPH) is used to study the mechanisms of landslide-generated waves. As the landslide dynamics and the evaluation of impact forces acting on water are most important, landslide is modelled as a highly viscous fluid. Incompressible SPH (ISPH) is used for fluid simulation. LÄS MER
