1. Multidirectional Mobilities - Advanced Measurement Techniques and Applications
Sammanfattning : Today high noise-and-vibration comfort has become a quality sign of products in sectors such as the automotive industry, aircraft, components, households and manufacturing. Consequently, already in the design phase of products, tools are required to predict the final vibration and noise levels. LÄS MER
2. Hybrid Methods for Unsteady Fluid Flow Problems in Complex Geometries
Sammanfattning : In this thesis, stable and efficient hybrid methods which combine high order finite difference methods and unstructured finite volume methods for time-dependent initial boundary value problems have been developed. The hybrid methods make it possible to combine the efficiency of the finite difference method and the flexibility of the finite volume method. LÄS MER
3. Hot-carrier generation and strong coupling in metal nanoparticles
Sammanfattning : Metal nanoparticles are an emerging platform for energy applications such as photovoltaics, solar-to-fuel conversion and photocatalysis. Nanoparticles confine the oscillating electromagnetic field of visible light to very small volumes, which allows for efficient absorption and scattering of light in the solar spectral range. LÄS MER
4. Acoustic source characterisation for non-linear in-duct sources
Sammanfattning : Different ways to model acoustic in-duct sources have beenanalysed. Measurements were conducted on two diesel truckengines. It was found that for steady state oscillations, onecould linearise in the neighbourhood of a given linearisationpoint, i.e. LÄS MER
5. Radiation and Scattering from Conformal Array Antennas
Sammanfattning : This thesis deals with radiation and scattering fromconformal array antennas. A hybrid technique between the Methodof Moments (MoM) and different asymptotic methods is used forthe analysis, combining the accuracy of the MoM and theefficiency of the asymptotic methods. LÄS MER
