2. Intramolecular electron transfer in DNA and ruthenium(II) systems
Abstract : When ruthenium(II) complexes with heteroaromatic ligands absorb light, an electron is pushed from the metal ion out into one of the ligands, a process called metal-to-ligand-charge-transfer (MLCT). The resulting excited state can be used to initiate further electron transfer processes, or it can decay relatively slow back into the ground state with the emission of light. READ MORE

3. Multiscale Constitutive Modeling of Heterogeneous Engineering Materials
Abstract : This work deals with different methods used to determine heterogeneous constitutive model parameters for macro-scale finite element models, based on microstructural variations, caused by the manufacturing process. These methods could be applied to decrease modeling errors associated with the material behavior, improving the predictive capabilities of structural analyses in simulation-driven industrial product development.

4. Process-Induced Local Material Variations in Finite Element Simulations of Cast and Fibre Reinforced Injection Moulded Components
Abstract : The purpose of this thesis is to provide an overview of the methods used in the appended papers, in order to consider heterogeneous material properties in finite element simulations by using process simulations as input. The work deals with both injection moulded and cast components, and focuses on process-induced local material variations and their effect on component performance. READ MORE

5. Machine Learning for Appearance Grading of Sawn Timber using Cameras and X-ray Computed Tomography
Abstract : This doctoral thesis deals with a new approach for the appearance grading of sawn timber adapted to the requirements of modern sawmilling industries and timber market situations. Appearance grading of sawn timber allows wood products to be made with a specific visual style due to wood features such as knots. READ MORE
