  2. 6. Improving the Efficiency of Control Signaling in Wireless Multiple Access Systems

    Author : Reza Moosavi; Erik G. Larsson; Danyo Danev; James Gross; Linköpings universitet; []
    Keywords : ;

    Abstract : Prior to the transmission of payload data in any multiple access system, there is generally a need to send control information such as scheduling assignments, transmission parameters and HARQ acknowledgments. This process is called control signaling and has a significant impact on the overall system performance. READ MORE

  4. 7. Aspects of vacuum moduli in string theory

    Author : Matthew Magill; Magdalena Larfors; James Sparks; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; string compactifications; g structures; homological algebra; Theoretical Physics; Teoretisk fysik;

    Abstract : In this thesis we explore geometric aspects of the space of vacua in supersymmetric string compactifications. More specifically, we will look at heterotic strings compactified on Calabi-Yau manifolds and, separately, G2 structure manifolds. READ MORE

  5. 8. Air mass boundary identification : improvement of precipitation phase determination in surface based modeling

    Author : James Feiccabrino; Per-Erik Jansson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Snowpack properties derived from hydrological models play an important role for many ecological, water resource, and climate applications; such as winter survival of plants, reindeer, small mammals and birds, avalanche hazards, glaciers and polar ice accumulation, growth of sea and lake ices, climate change, snow melt flooding etc. These hydrological models need accurate precipitation phase discrimination schemes to closely portray e.

  6. 9. Haptic Milling Simulation in Six Degrees-of-Freedom : With Application to Surgery in Stiff Tissue

    Author : Magnus G. Eriksson; Jan Wikander; Dwight Meglan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surgical simulation; Virtual reality; Haptic feedback; Surgical training; Medical simulators; 3D visualization; Six degrees-of-freedom; Bone milling;

    Abstract : The research presented in this thesis describes a substantial part of the design of a prototypical surgical training simulator. The results are intended to be applied in future simulators used to educate and train surgeons for bone milling operations. READ MORE

  7. 10. Comparative analysis of the thermogenic protein UCP1 across the mammalian phylogeny

    Author : Michael James Gaudry; Martin Jastroch; Tobias Wang; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Uncoupling protein 1; Evolution; Non-shivering thermogenesis; Brown adipose tissue; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Uncoupling protein 1 (UCP1) drives mitochondrial inefficiency to produce heat in mammalian brown adipose tissue (BAT). Many mammalian species rely on this form of adaptive non-shivering thermogenesis (NST) to defend high body temperatures in the cold. READ MORE
