16. Internal oxidation processing : New alloys and new simulation techniques
Sammanfattning : Nitriding and oxidising treatments of alloys for toolingpurposes have been investigated both experimentally andtheoretically. Specimens prepared by a combination of differentprocessing steps are investigated by light-optical, scanningand transmission electron microscopy and hardness measurments. LÄS MER
17. Light propagation and photonic functionalization of semi-ordered material (transparent wood)
Sammanfattning : Investigating novel materials requires understanding their chemical and optical properties, which allows for finding their uses through functionalization by chemical modification. In this thesis, we are focusing on a material with high anisotropic scattering - transparent wood. LÄS MER
18. Essays on energy efficiency, environmental regulation and labor demand in Swedish industry
Sammanfattning : Paper [I] Energy efficiency improvement (EEI) benefits the climate and matters for energy security. The potential emission and energy savings due to EEI may however not fully materialize due to the rebound effect. LÄS MER
19. Human-structure interaction effect on the dynamic response of footbridges : An analytical and experimental study
Sammanfattning : Lightweight, slender and lightly damped footbridges are often susceptible to HumanInduced Loads (HILs) when pedestrian step frequencies coincide with the naturalfrequencies of the structure. For vertical vibrations, this can compromise the serviceabilitylimit state of the system. LÄS MER
20. The Influence of Atmospheric Turbulence on Barrier Sound Reduction
Sammanfattning : Numerical modelling and measurements are used for studying the reduced performance of a noise barrier, caused by a turbulent atmosphere. The turbulence scatters the sound, which leads to an increased noise level in the acoustic shadow region behind the barrier. LÄS MER
