16. Analysis of Cellular and Cell-Free Massive MIMO with Rician Fading
Abstract : The data traffic in cellular networks has grown at an exponential pace for decades. This trend will most probably continue in the future, driven by new innovative applications. One of the key enablers of future cellular networks is the massive MIMO technology. A massive MIMO base station is equipped with a massive number (e. READ MORE

17. Theoretical Studies of Natural Gas Hydrates and H-bonded Clusters and Crystals
Abstract : In this thesis H-bonded systems (natural gas hydrates, water clusters, and crystal ice) are studied by density functional theory (DFT) computations.Natural gas hydrates (NGHs) play an important role in energy and environmental fields: NGHs are considered as a promising backup energy resource in the near-future due to their tremendous carbon content; improper exploration of NGHs could induce geological disasters and aggravate the greenhouse effect.

18. Functional Materials for Perovskite Solar Cells
Abstract : Energy plays a significant role in our daily lives, but most energy provided by fossil fuels causes serious environmental problems including air pollution, global warming, and ecological damage. In addition, it has been estimated that all of our fossil fuels will run out in 2088 and thus it is highly important to study and apply renewable energy sources. READ MORE

19. Embryonic Stem Cells: Differentiation into Insulin Producing Cells and Elimination of Damaged Proteins
Abstract : This thesis includes two different parts: One focusing on how to induce human embryonic stem cells (hESCs) to differentiate into insulin producing cells by following the normal pancreatic development pathway. These cells have then the potential to be an unlimited source for diabetes regenerative medicine. READ MORE

20. Breast Tomosynthesis: Aspects on detection and perception of simulated lesions
Abstract : The aim of this thesis was to investigate aspects on detectability of simulated lesions (microcalcifications and masses) in digital mammography (DM) and breast tomosynthesis (BT). Perception in BT image volumes were also investigated by evaluating certain reading conditions. READ MORE
