1. Laser sintered materials with Non-equilibrium structures
Abstract : This thesis is focused on achieving materials with non-equilibrium structures fabricated by high-energy laser sintering. The chosen precursor materials have rigid and inert structures like high-melting point ceramics or metals. READ MORE

2. Multimodal Imaging of Anisotropic Hierarchical Materials
Abstract : The thesis is focused on studying the nanostructure of natural and synthetic hierarchical materials with biological applications, using X-ray scattering imaging and birefringence microscopy. The term "hierarchical materials" is used for structures composed of sub-units organised in different length scales that create the building blocks for the next level. READ MORE

3. On Postbuckling Analysis of Thin-walled Structures Numerical and Statistical Approaches
Abstract : Thin-walled structural elements, such as plates, shells and beams are important load carrying components in civil-, mechanical-, automotive- aeronautical- and marine engineering structures. In order to reduce the weight thin-walled structures are given an optimum design making them sensitive to unforeseen deviations in geometry, boundary conditions, material properties and applied loads.

4. Hierarchical structures and extended motion information for video coding
Abstract : The thesis describes usage and generation of motion information in the field of video coding. Hierarchical structures for computation of this motion information are suggested. These hierarchical structures can be used also for other applications. READ MORE

5. Integrated Cellulosic Wood Aerogel Structures
Abstract : Highly porous aerogels based on renewable materials that possess structural functionality are appealing for sustainable energy regulation and harvesting. Achieving structural anisotropy provides advantageous directional diffusion and mechanical strength, however, introduces great engineering challenges, such as complex, costly, and time-consuming processing.
