1. Model Studies of Surface Waves and Sediment Resuspension in the Baltic Sea
Abstract : Wave heights and periods of surface waves in the Baltic Sea have been modelled for a two-year period (1999-2000) with the wave model Hypas on an 11x11-km grid scale. There is a clear seasonal variation with higher waves during winter and lower during summer. READ MORE

2. Direct and inverse resonance problems for seismic surface waves
Abstract : This thesis concerns the investigation of direct and inverse resonance results for the Love and the Rayleigh operators, which arise from decoupling the three-dimensional elastic wave equation in the semiclassical limit in the half-space. Direct resonance results in terms of the asymptotic distribution of resonances in the complex plane are obtained for the Love and the Rayleigh operators. READ MORE

3. Three-component digital-based seismic landstreamer : Methodologies for infrastructure planning applications
Abstract : To support urban infrastructure planning projects, along with various other near-surface applications, a multicomponent landstreamer was developed. The landstreamer was built with broadband (0-800 Hz), three-component (3C) micro-electro-mechanical system (MEMS) sensors. READ MORE

4. Surface Wave Testing of Pavements
Abstract : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. READ MORE

5. Air-coupled microphone measurements of guided waves in concrete plates
Abstract : Quality control and quality assurance of pavements is today primarily based on core samples. Air void content and pavement thickness are parameters that are evaluated. However, no parameter connected to the stiffness is evaluated. READ MORE
