1. Theoretical modeling of scanning tunneling microscopy
Abstract : The main body of this thesis describes how to calculate scanning tunneling microscopy (STM) images from first-principles methods. The theory is based on localized orbital density functional theory (DFT), whose limitations for large-vacuum STM models are resolved by propagating localized-basis wave functions close to the surface into the vacuum region in real space.

2. Modeling of non-equilibrium scanning probe microscopy
Abstract : The work in this thesis is basically divided into two related but separate investigations.The first part treats simple chemical reactions of adsorbate molecules on metallic surfaces, induced by means of a scanning tunneling probe (STM). The investigation serves as a parameter free extension to existing theories. READ MORE

3. Electromagnetic Dispersion Modeling and Analysis for Power Cables
Abstract : This thesis addresses electromagnetic wave propagation in power cables. It consists of five papers, where the three first papers are based on one and the same model, and the last two papers are based on a similar but slightly different model. READ MORE

4. Parameter and State Estimation with Information-rich Signals
Abstract : The complexity of industrial systems and the mathematical models to describe them increases. In many cases, point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. READ MORE

5. Ways forward : Effectual and causal approaches to innovation in the Swedish magazine industry
Abstract : This dissertation builds on a study of key decision makers in the Swedish magazine publishing industry with a particular focus on how they think and act in their work to innovate their industry. This industry, much like the rest of the media industry, is facing increased unpredictability regarding for example the impact of new technology on the business and future demand. READ MORE
