1. Information Technology Alignment in Public Organisations : Towards Successful Digital Transformation
Sammanfattning : The widespread acceptance of digital transformation has brought the topic to the top of researchers’ and practitioners’ agendas. However, despite the anticipated benefits and opportunities, evidence suggests that many organisations still struggle to realise the results of successful digital transformation. LÄS MER
2. Matrix Algebra for Quantum Chemistry
Sammanfattning : This thesis concerns methods of reduced complexity for electronic structure calculations. When quantum chemistry methods are applied to large systems, it is important to optimally use computer resources and only store data and perform operations that contribute to the overall accuracy.

3. Skew-symmetric matrix pencils : stratification theory and tools
Sammanfattning : Investigating the properties, explaining, and predicting the behaviour of a physical system described by a system (matrix) pencil often require the understanding of how canonical structure information of the system pencil may change, e.g., how eigenvalues coalesce or split apart, due to perturbations in the matrix pencil elements.

4. Gravity Illustrated. Spacetime Edition
Sammanfattning : This thesis deals with essentially four different topics within general relativity: pedagogical techniques for illustrating curved spacetime, inertial forces, gyroscope precession and optical geometry. Concerning the pedagogical techniques, I investigate two distinctly different methods, the dual and the absolute method. LÄS MER
5. The Relation Between Digital Technology and Values : Thinking Through Multiple Technologies
Sammanfattning : This thesis addresses two topics: technology and values. More specifically, the studied technology is an ensemble of digital technologies that is often referred to as “digitalization,” and the values are gathered from empirical material from the Swedish (digital) government. LÄS MER
