1. Phase-field modeling of diffusion controlled phase transformations
Sammanfattning : Diffusion controlled phase transformations are studied bymeans of the phase-field method. Morphological evolution ofdendrites, grains and Widmanst\"atten plates is modeled andsimulated.Growth of dendrites into highly supersaturated liquids ismodeled for binary alloy solidification.

2. Frequency Noise in Coherent Optical Systems: Impact and Mitigation Methods
Sammanfattning : The increase in capacity demand along with the advancement in digital signal processing (DSP) have recently revived the interest in coherent optical communications and led to its commercialization. However, design and development of robust DSP algorithms for example for carrier phase recovery (CPR) becomes complex as we opt for high order modulation formats such as 16QAM and beyond. LÄS MER
3. Solvable Topological Boundaries
Sammanfattning : The hallmark of topological phases of matter is the presence of robust boundary states. In this dissertation, a formalism is developed with which analytical solutions for these states can be straightforwardly obtained by making use of destructive interference, which is naturally present in a large family of lattice models.

4. Organizing boundaries in early phases of product development : The case of an interorganizational vehicle platform project setting
Sammanfattning : This dissertation concerns the development of a new interorganizational vehicle platform in the truck industry. The studied project setting was large, and can be referred to as a mega project. LÄS MER
5. Atomic-scale modelling of interfaces in cemented carbides: wetting and strength
Sammanfattning : Cemented carbides are composite materials of great technological and industrial importance. They have a unique combination of hardness and toughness and are therefore used widely as tool materials in applications where both high hardness and toughness are demanded. These applications include among others: mining, turning, cutting and milling. LÄS MER
