1. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling
Sammanfattning : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. LÄS MER
2. Studies in conflict economics and economic growth
Sammanfattning : “Armaments and Economic Performance”. The literature on military expenditure (milex) is scrutinized with respect to five areas. Investment is reduced when milex increases. Most studies have found economic growth hindered by higher milex. LÄS MER
3. On measurement, assessment and control of diesel engine noise
Sammanfattning : The thesis comprises six papers with the overall theme of measurement, assessment and control of diesel engine noise, with an emphasize on control. The radiation of noise is shown to be dominated by the low end of the engine sides and by the engine front. LÄS MER
4. Fluid Mechanics of Vertical Axis Turbines : Simulations and Model Development
Sammanfattning : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. LÄS MER
5. Coil Design and Related Studies for the Fusion-Fission Reactor Concept SFLM Hybrid
Sammanfattning : A fusion-fission (hybrid) reactor is a combination of a fusion device and a subcritical fission reactor, where the fusion device acts as a neutron source and the power is mainly produced in the fission core. Hybrid reactors may be suitable for transmutation of transuranic isotopes in the spent nuclear fuel, due to the safety margin on criticality imposed by the subcritical fission core. LÄS MER
