11. 60 GHz Mixer and Multifunctional MMICs in GaAs pHEMT and mHEMT technologies
Abstract : In recent years, the 60 GHz band has gained increased academic and commercial interest mainly due to the relative large amount of license free and little used frequency spectrum located in vicinity of 60 GHz. The exact locations of these free frequency bands varies locally but the 5962 GHz band overlap around the world and is therefore a true world wide license free band. READ MORE

12. Mixers and Multifunctional MMICs for Millimeter-Wave Applications
Abstract : This thesis treats the design and characterization of different mixer and multifunctional monolithic microwave integrated circuits (MMICs) in GaAs pHEMT and mHEMT technologies. The MMICs operate at the V (50 – 75 GHz) and G (140 – 220 GHz) bands and several of them demonstrate state-of-the-art performance, level of integration, novel topologies, and/or novel functionality.

13. Millimeter-wave Transceiver ICs for Ultrahigh Data Rate Communications Using Advanced III-V and Silicon Technologies
Abstract : Today’s main driving parameter for radio transceiver research is the ability to provide high capacity while maintaining low cost, small form factor, and low power consumption. Direct conversion architectures (due to the feasibility of monolithic integration) at millimeter-wave (due to wideband availability) have attracted large interest in recent years because of their potential to meet these demands.

14. Studies of Spinal Motor Control Networks in Genetically Modified Mouse Models
Abstract : Spinal neurons are important in several aspects motor control. For example, the neurons essential for locomotor movements reside in the ventral spinal cord. In this thesis, different motor control functions are being related to neuronal populations defined by their common expression of a gene. READ MORE

15. The birds in the Iliad. Identities, interactions and functions
Abstract : As the topic of this study embraces and entwines what is routinely divided into two separate categories, “nature” and “culture”, the birds in the Iliad challenge modern scientific division and in some ways, our thinking. They are simultaneously birds, signs and symbols. READ MORE
