  2. 1. Efficient Density-Functional-Based Calculational Methods for Surfaces

    Author : Lennart Bengtsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; potential energy surfaces; pseudopotentials; surface physics; density functional theory; optimization techniques; computer simulations;

    Abstract : During the last decades, computer simulations have become an important tool for the study of elementary surface processes, such as atomic and molecular adsorption, diffusion of ad-atoms and surface recombination. The knowledge gained by such studies can be used to understand and develop technologically important processes such as catalysis and crystal growth. READ MORE

    Abstract : The advent of technological furtherance in the biomedical sector and the renaissance of interdisciplinary science enable us to comprehend human lifestyle, and diseases at molecular and nanoscale levels. Lacking a shared theoretical foundation and terminological lexicon between various scientific domains might impede efforts to incorporate biological principles into nanoscience. READ MORE

  7. 5. Optimal Decisions in the Equity Index Derivatives Markets Using Option Implied Information

    Author : Mathias Barkhagen; Jörgen Blomvall; Alan J. King; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Option implied information; Optimal decisions; Equity index derivatives; Stochastic programming; Local volatility surface; Real-world density;

    Abstract : This dissertation is centered around two comprehensive themes: the extraction of information embedded in equity index option prices, and how to use this information in order to be able to make optimal decisions in the equity index option markets. These problems are important for decision makers in the equity index options markets, since they are continuously faced with making decisions under uncertainty given observed market prices. READ MORE
