  1. 16. Numerical study of a vibroacoustic wave trap for e-vehicles

    University essay from KTH/Teknisk akustik

    Author : Antoine Curien; [2022]
    Keywords : wheel vibrations; passive vibration control; multiple tuned mass damper; bending mode; numerical optimisation; damping; resonance; robustness; reduction methods; Hjulvibrationer; passiv vibrationsreglering; multi tuned mass damper; böjningsläge; numerisk optimering; dämpning; resonans; robusthet; modale reduktionsmetoder;

    Abstract : The transition from internal combustion engine to battery electric cars is accompanied by a shift on the NVH issues damaging the passenger comfort. The rolling noise generated by the wheels and tyres is in particular characterized by an increasing attention from OEMs and car manufacturers. READ MORE

  3. 17. Modeling of optical microresonator frequency combs

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Michael Ekström; [2022]
    Keywords : Optical frequency combs; Nonlinear optics; Temporal cavity solitons;

    Abstract : An optical frequency comb is a structure of equidistant, coherent spectral components which can be thought of as a large array of individual phase-locked laser sources. Their utilization in precision spectroscopy garnering part of the 2005 Nobel prize, optical frequency combs constitute a relatively novel technology with a large number of potential and actual applications.

  4. 18. Error estimation for neural network approximations of convection problems

    University essay from KTH/Matematik (Avd.)

    Author : Ludvig Eidmann; [2022]
    Keywords : ;

    Abstract : The problem of approximating a solution to the convection equation $\partial_t u +f\cdot\nabla_xu = h$ given data on the flux $f$, source function $h$ and a final condition $g$ is investigated. Specifically, two layer neural networks are used to approximate $f,h$ and $g$ and a solution is approximated using numerical integration. READ MORE

  5. 19. Simulation of Transformer Inrush Currents and Their Impact on the Grid

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Juan de la Peña Toledo; [2022]
    Keywords : Transformer; Energization; PSS E; PSCAD; Simulation; Magnetizing current; Inrush current; Technology and Engineering;

    Abstract : This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E. READ MORE

  6. 20. The K-distribution method for calculating thermal infrared radiative transfer in the atmosphere : A two-stage numerical procedure based on Gauss-Legendre quadrature

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Karl Nerman; [2022]
    Keywords : The K-distribution method; thermal infrared radiative transfer; Gauss-Legendre quadrature; numerical integration; MATLAB;

    Abstract : The K-distribution method is a fast approximative method used for calculating thermal infrared radiative transfer in the atmosphere, as opposed to the traditional Line-by-line method, which is precise, but very time-costly. Here we consider the atmosphere to consist of homogeneous and plane-parallel layers in local thermal equilibrium. READ MORE
