2. 6. Millimeter-Wave High-Gain Antenna for 5G Backhauling with Auto-beam-tracking Function

   Author : Enlin Wang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gap waveguide; auto-beam-tracking; 5G backhaul; Ultra-high-gain antenna; me- chanical movement;

   Abstract : As microwave links are increasingly deployed within the millimeter-wave frequency range, E-band (70/80 GHz) links have been installed on a global scale. One major technological challenge in this high-frequency spectrum is the significant increase in path loss between receivers and transmitters. READ MORE

4. 7. Dead-Ice Under Different Climate Conditions: Processes, Landforms, Sediments and Melt Rates in Iceland and Svalbard

   Author : Anders Schomacker; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; klimatologi; glacier; dead-ice; surge; ice-cored; Little Ice Age; fysisk geografi; Geologi; Geology; Svalbard; Iceland; Sedimentology; cartography; pedology; geomorphology; Sedimentologi; Physical geography; geomorfologi; marklära; kartografi; climatology;

   Abstract : Modern dead-ice environments in the glacier forefields of Brúarjökull, Iceland and Holmströmbreen, Svalbard were investigated with focus on landform and sediment genesis, as well as quantification of melting. Field monitoring and studies of multi-temporal aerial photographs, satellite imagery, and Digital Elevation Models (DEMs) provided data for the melting quantification. READ MORE

5. 8. Population-level consequences of spatial interactions

   Author : Henrik Sjödin; Göran Englund; Åke Brännström; Per Lundberg; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : How is the nature of populations governed by the movement decisions made by their members? This is the core question in this thesis. To answer this question, I first assume that s movement decisions are based on conditions in their local environment. READ MORE

6. 9. Land rent, capital, rate of profit : A critique of Harvey’s model of urban land rent

   Author : Ilia Farahani; Institutionen för kulturgeografi och ekonomisk geografi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban Land Rent; Capitalist Urbanization; Rate of Profit; Absolute Rent; Spatial Monopoly Model of Land Rent; Turbulent Inter-Sectoral Model of Land Rent; David Harvey; Urban Economic Geography; Urban Land Rent; Capitalist Urbanization; Rate of Profit; Absolute Rent; Spatial Monopoly Model of Land Rent; Turbulent Inter-Sectoral Model of Land Rent; David Harvey; Urban Economic Geography;

   Abstract : This study critically evaluates David Harvey’s model of urban land rent and its centrality in his explanation of the material forces that underlie and limit urban land policies, strategies, planning decisions, and investment choices. Harvey emphasizes structural forces of capital in relating economic urbanization processes to uneven patterns of capitalist development, recurrent economic crises of overaccumulation, and the need to produce spaces of accumulation to absorb surplus capital that creates crises.

7. 10. Mobility and emigration in butterflies

   Author : Karin Enfjäll; Olof Leimar; Michel Baguette; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Keywords: conspecific density; dispersal; evolution; flight-behaviour; information; sexual conflict; social interactions; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

   Abstract : Because of its implications for the survival of many species, dispersal plays a key role in conservation biology. A good knowledge about the different factors that influence dispersal decisions is crucial for the understanding of inter-population movements. READ MORE
