1. Reversible architecture : Reuse of timber building parts in circular design
Abstract : The construction industry has a great impact on the environment but there is a great potential for improvements. In the era of climate change, sustainable construction methods and ecological solutions are required to improve energyefficiency, and to decrease the environmental impact of housing development.

2. High order summation-by-parts methods in time and space
Abstract : This thesis develops the methodology for solving initial boundary value problems with the use of summation-by-parts discretizations. The combination of high orders of accuracy and a systematic approach to construct provably stable boundary and interface procedures makes this methodology especially suitable for scientific computations with high demands on efficiency and robustness.

3. Applications of summation-by-parts operators
Abstract : Numerical solvers of initial boundary value problems will exhibit instabilities and loss of accuracy unless carefully designed. The key property that leads to convergence is stability, which this thesis primarily deals with. READ MORE

4. Improved high velocity cold copaction processing : polymer powder to high performance parts
Abstract : A uniaxial High-Velocity Compaction (HVC) process for polymer powder using a cylindrical, hardened steel die and a new technique with relaxation assist was tested with a focus on the compactibility characteristics and surface morphology of the compacted materials using various heights of relaxation assist device with different compacting profiles. Relaxation assist device was presented as a new technique to reduce springback, pull-out phenomenon and to improve the compaction process. READ MORE

5. Seeing the parts, understanding the whole : A technology education perspective on teaching and learning in processes of analysing and designing programmed technological solutions
Abstract : Analysing and designing Programmed Technological Solutions (PTS) has been introduced as a part of technology education in an effort to bring elements of programming into the curriculum for compulsory school, in order to develop pupils’ understanding of how PTS work and are controlled by programming. However, what an appropriate understanding entails at this level remains to be articulated, particularly how this understanding looks from a pupil’s perspective. READ MORE
