11. Multi-Functional Composite Design Concepts for Rail Vehicle Car Bodies
Sammanfattning : Structures and material combinations, tailored for multiple purposes, are within the reach of vehicle manufacturers. Besides reducing the environmental impact of the transportation sector these multi-functional structures can reduce costs, such as development, manufacturing and maintenance, and at the same time offer improved comfort to the passengers.

12. Textile architecture informed by wind
Sammanfattning : Textiles in architecture is a field of great potential, which are worth to explore further. This thesis aims to show that the flexibility of the textile material could be better included in the architectural design, allowing it to adapt to forces, such as the wind, and viewing motion as a positive design feature.

13. Vibrations in lightweight structures - Efficiency and reduction of numerical models
Sammanfattning : Multi-storey wood buildings have been increasing in popularity since a century-old ban on the construction of such buildings was lifted in 1994. Compared to conventional concrete structures, it is more difficult to build lightweight structures in such a way that noise and disturbing vibrations is avoided. LÄS MER
14. Structure-acoustic analysis; finite element modelling and reduction methods
Sammanfattning : This thesis investigates structure-acoustic systems by use of finite element analysis. The systems studied here are limited to those that consist of an enclosed acoustic fluid cavity, which is coupled to a flexible structure and/or a porous sound absorbing material domain. LÄS MER
15. Sustainable Surface Functionalization of Lightweight Materials : Cerium Oxide Nanoparticles Replacing Chromium in Anodic Coatings and Carbon Nanomaterials for Lightning Strike Protection
Sammanfattning : Aviation accounts for 2-3% of the carbon dioxide emitted globally. One way to reduce emissions is to develop and introduce sustainable, functional, lightweight materials and coatings that increase the lifetime and fuel efficiency of aircraft. LÄS MER
