  1. 1. Investigation of Novel Metal Gate and High-κ Dielectric Materials for CMOS Technologies

    Author : Jörgen Westlinder; Jörgen Olsson; Stefan Bengtsson; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; metal gate; high-κ dielectics; titanium nitride; zirconium nitride; MOSFET; thin film; tantalum oxide; aluminum nitride; Elektronik; Electronics; Elektronik;

    Abstract : The demands for faster, smaller, and less expensive electronic equipments are basically the driving forces for improving the speed and increasing the packing density of microelectronic components. Down-scaling of the devices is the principal method to realize these requests. READ MORE

  3. 3. Low Frequency Impact Sound in Timber Buildings : Transmission Measurements and Simulations

    Author : Jörgen Olsson; Andreas Linderholt; Börje Nilsson; Carl Hopkins; Linnéuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timber floors; FE-simulations; Light weight floors; Frequency response functions; Building acoustics; Byggteknik; Civil engineering;

    Abstract : An increased share of multi-story buildings that have timber structures entails potential in terms of increased sustainability as well as human-friendly manufacturing and habitation. Timber buildings taller than two stories were prohibited in Europe until the 1990s due to fire regulations. In 1994, this prohibition was removed in Sweden. READ MORE

  4. 4. Colonization Patterns of Wood-inhabiting Fungi in Boreal Forest

    Author : Jörgen Olsson; Lars Ericson; Jørund Rolstad; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Wood-inhabiting fungi; colonization; dispersal; restoration fire; saproxylic beetles; conservation; forest management; boreal forest; Terrestrial ecology; Terrestisk ekologi;

    Abstract : Forest management practices have changed the over-all structure of the Fennoscandian forest landscape resulting in a lack of suitable substrates for many wood-inhabiting species. The objectives of this thesis was to describe the colonization patterns of wood-inhabiting fungi, including the potential role of beetles as dispersal vectors, on different types of dead wood substrate and assess the importance of active measures in the forest landscape in order to restore biodiversity i.
