  1. 6. Analysis of the Representation of Orbital Errors and Improvement of their Modelling

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Mini Gupta; [2018]
    Keywords : Space debris; space situational awareness; uncertainty characteristics; Gaussianity;

    Abstract : In Space Situational Awareness (SSA), it is crucial to assess the uncertainty related to thestate vector of resident space objects (RSO). This uncertainty plays a fundamental role in, forexample, collision risk assessment and re-entry predictions. A realistic characterization of thisuncertainty is, therefore, necessary. READ MORE

  3. 7. Experimental and numerical fluid-structure interaction analysis of a suspended rod subjected to forced vibrations

    University essay from KTH/Marina system

    Author : David Ahlsén; [2018]
    Keywords : ;

    Abstract : This study is evaluating Solid-Acoustic Finite Element modelling as a method for calculating structural vibration response in water. When designing for example vehicles, it is important to avoid vibrational resonance in any part of the structure, as this causes additional noise and reduced lifespan. READ MORE

  4. 8. Analysis and Implementation of an Age Structured Model of the Cell Cycle

    University essay from Lunds universitet/Matematik LTH

    Author : Anna Broms; [2017]
    Keywords : age structured model; cell cycle; cell population dynamics; nonlinear integral equations; Romberg s method; Mathematics and Statistics;

    Abstract : In an age-structured model originating from cancer research, the cell cycle is divided into two phases: Phase 1 of variable length, consisting of the biologically so called G1 phase, and Phase 2 of fixed length, consisting of the so called S, G2 and M phases. A system of nonlinear PDEs along with initial and boundary data describes the number densities of cells in the two phases, depending on time and age (where age is the time spent in a phase).

  5. 9. Large-scale multiscale particle models in inhomogeneous domains

    University essay from

    Author : Omar Richardson; [2016]
    Keywords : crowd dynamics stochastic partial differential equations simulation numerical analysis;

    Abstract : In this thesis, we develop multiscale models for particle simulations in population dynamics. These models are characterised by prescribing particle motion on two spatial scales: microscopic and macroscopic. READ MORE

  6. 10. Structure-borne sound transmission in wall-floor timber junctions with damping elastomers

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Sarah Stenberg; Adrien Vercruysse; [2016]
    Keywords : Elastomers; Sound Flanking Transmission; Vibrations Flanking Transmission; Wall-floor junctions; Structural Dynamics;

    Abstract : The wooden multi-storey building industry is facing persistent sound transmission problems at low frequencies. Inserting elastomers within wall-floor junctions is common usage nevertheless no accurate studies have elucidated the real behavior of those nonlinear combined materials yet. READ MORE
