6. Twist-Symmetric Periodic Structures : Properties and Applications
Abstract : In this thesis, periodic structures with higher symmetries symmetries are discussed. The main focus of the thesis is on twist symmetries. Importantly, the attractive properties of twist symmetries for the control of electromagnetic wave propagation are demonstrated. READ MORE

7. Strengthening of timber structures with flax fibres
Abstract : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. READ MORE

8. Analysis of Planar and Circular Cylindrical Multilayer Structures with Application to Soft and Hard Surfaces
Abstract : This thesis deals with the analysis of planar and circular cylindrical multilayer structures, such as strip-loaded dielectric layers, corrugated surfaces and microstrip antennas. In particular, we study corrugations and strip-loaded grounded dielectric slabs when they are used to realize soft and hard surfaces. READ MORE

9. Ductility in high performance concrete structures : an experimental investigation and a theoretical study of prestressed hollow core slabs and prestressed cylindrical poles
Abstract : The thesis presents results from a project dealing with ductility in high performance concrete structures. The main objectives were to investigate the material and structural ductility/brittleness of prestressed structural elements of High Performance Concrete (HPC). READ MORE

10. Periodic Structures with Higher Symmetries: Analysis and Applications
Abstract : In this thesis, periodic structures with higher symmetries are studied. Their wave propagation characteristics are investigated and their potential applications are discussed. Higher-symmetric periodic structures are described with an additional geometrical operation beyond a translation operator. READ MORE
