1. Oxy-coal combustion and its integration with power systems for CO2 capture
Abstract : Oxy-fuel combustion is one of the technologies for carbon dioxide (CO2) capture and storage (CCS) in fossil fuel based power systems to mitigate global greenhouse gases (GHGs) emissions. When introducing oxy-fuel combustion into the power systems, energy penalty for CCS has significant impacts on the system performance. READ MORE

2. Costs in Swedish Public Transport : An analysis of cost drivers and cost efficiency in public transport contracts
Abstract : During the last seven years, the total cost for Swedish public transport provision has increased by over 30 percent in real terms according to figures from the government agency Transport Analysis. A similar pattern is found if considering a longer time span. READ MORE

3. Process modelling based on data from an evaporation and a CTMP process : Analysis of energy efficiency and process variability
Abstract : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, paperboard, steam and other important components. Improved energy efficiency supports sustainability of the process and the products. READ MORE

4. Multidimensional Modulation Formats for Coherent Single- and Multi-Core Fiber-Optical Communication Systems
Abstract : This thesis covers multidimensional modulation formats for coherent optical communication systems including spatial division multiplexed systems using multicore fibers. The single-mode optical signal has four dimensions which are spanned by the two orthogonal polarizations and the in-phase and quadrature components. READ MORE

5. Modular long-span timber structures : a systematic framework for buildable construction
Abstract : One of the identified reasons for the low amount of timber construction in Sweden is a general lack of knowledge about timber engineering and how timber can be used to its full advantage. One way for increased timber construction is the development of a cost-efficient and easy to comprehend building system. READ MORE
