1. Swedish Dimensional Adjectives
Abstract : The purpose of this study is to give a thorough and detailed account and analysis of the semantics of twelve Swedish dimensional adjectives: hög ’high/tall’, låg ’low’, bred ’broad/wide’, smal ’narrow’ vid ’broad’, trång ’narrow’, tjock ’thick’, tunn ’thin’, djup ’deep’, grund ’narrow’, lång ’long’ and kort ’short’. Focus has been placed on their spatial, non-metaphorical sense. READ MORE

2. Aspects of Dimensional Deconstruction and Neutrino Physics
Abstract : The existence of at or curved extra spatial dimensions provides new insights into several of the problems which face the Standard Model of particle physics, including the gauge hierarchy problem, the smallness of neutrino masses, and the dark matter problem. However, higher-dimensional gauge theories are not renormalizable and can only be considered as low-energy effective theories, with limited applicability. READ MORE

3. Crystallography in Four Dimensions : Methods and Applications
Abstract : The four-electron reduction of dioxygen to water is the most exothermic non-photochemical reaction available to biology. A detailed molecular description of this reaction is needed to understand oxygen-based redox processes. Horseradish peroxidase (HRP) is a haem-containing redox enzyme capable of catalysing the reduction of dioxygen to water. READ MORE

4. Fiber-Optic Systems with Coherent Detection and Four-Dimensional Modulation
Abstract : To increase the data rates of fiber-optic communication systems, modulation formats withhigher spectral efficiency and/or higher power efficiency than binary formats are of greatinterest. These formats require coherent detection and this thesis has been dedicated toinvestigating both novel modulation formats and two different types of coherent systems. READ MORE

5. Parties, Majorities, Incumbencies : Four essays in political economics
Abstract : This thesis consists of four self-contained essays on political economics. The first paper studies the impact of having one party in government versus a coalition of parties, where the exogenous variation in the type of government stems from close election outcomes. READ MORE
