21. Advances in Time-gated Ballistic Imaging for Studies of Atomizing Fuel Sprays
Abstract : The transportation sector of today relies heavily on fossil fuels. This is undesirable both due to the finite nature of the fossil resources and to the effects of global warming. Therefore, there is a need to find alternative fuels and simultaneously develop combustion engines with higher efficiencies. READ MORE

23. Iterative Methods for Solving the Cauchy Problem for the Helmholtz Equation
Abstract : The inverse problem of reconstructing the acoustic, or electromagnetic, field from inexact measurements on a part of the boundary of a domain is important in applications, for instance for detecting the source of acoustic noise. The governing equation for the applications we consider is the Helmholtz equation. READ MORE

25. Wave Modelling Techniques for Medium and High Frequency Vibroacoustic Analysis Including Porous Materials
Abstract : Numerical methods based on wave modelling are explored for the vibroacoustic analysis of wave propagation, sound transmission and interior noise in vehicles and buildings at medium and high frequencies. The presence of sound absorbing porous materials in practical engineering structures is also considered. READ MORE
