1. 11. Critical loads - assessment of uncertainty

   Författare :Andreas Barkman; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landscape planning; regionalisation; forestry; BC Al; sensitivity analysis; risk assessment; Monte Carlo simulation; PROFILE; critical level; exceedance; Acidification; forest soil; policy; EMEP; GIS.; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Sammanfattning : The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. LÄS MER

3. 12. Modelling District Heating Network Costs

   Författare :Luis Sánchez-García; Urban Persson; Helge Averfalk; Erik Möllerström; Marcus Thern; Magnus Åberg; Sweden Lund Lund University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District Heating; Pipe network; Cost analysis; Distribution Capital Cost; Effective Width; Plot Ratio; Heat Density; GIS; Smart Cities and Communities; Smarta städer och samhällen;

   Sammanfattning : The solution of the undergoing climate and energy crises requires a radical transformation of the energy system, in which sustainability, no carbon emissions and energy efficiency ought to play a paramount role. This revolution should extend to all areas of the energy system, including the space heating and cooling sector, which accounts for a third of the European final energy demand and, in the European continent, it is still mostly supplied by fossil fuels.

4. 13. Topological and Scaling Analysis of Geospatial Big Data

   Författare :Ding Ma; Bin Jiang; Shaowen Wang; Högskolan i Gävle; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Third definition of fractal; scaling; topology; power law; head tail breaks; ht-index; complex network; geospatial big data; natural cities; natural streets; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Geographic information science and systems face challenges related to understanding the instinctive heterogeneity of geographic space, since conventional geospatial analysis is mainly founded on Euclidean geometry and Gaussian statistics. This thesis adopts a new paradigm, based on fractal geometry and Paretian statistics for geospatial analysis. LÄS MER

5. 14. Radon in natural waters : Analytical Methods; Correlation to Environmental Parameters; Radiation Dose Estimation; and GIS Applications

   Författare :Isam M. Musa Salih; Eva Lund; Håkan B.L. Pettersson; Christer Samuelsson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radon analysis; radiation effects; Water chemistry; Water pollution; radioactive analysis; Radiological physics; Radiofysik;

   Sammanfattning : Investigations of radon in natural water and its relation to physical and chemical parameters are outlined in this thesis. In particular, a method for measuring 222Rn in water at low concentrations (~20 mBq. LÄS MER

7. 15. Changes, Activities and Bones : Intra-site analysis of the Pitted Ware Culture site Ajvide on the Baltic Sea island of Gotland

   Författare :Alexander Sjöstrand; Sabine Sten; Paul Wallin; Gustaf Svedjemo; Kristiina Mannermaa; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Osteology; GIS; Archaeology; Stone Age; Middle Neolithic; Pitted Ware Culture; Bourdieu; practice theory; Gotland; Ajvide; ritual.; Archaeology; Arkeologi;

   Sammanfattning : In this dissertation the structure, practices and evolution of a single Pitted Ware Culture site, Ajvide on Gotland, is explored and placed within the larger Pitted Ware Culture context. The site has been excavated over a period of 24 years, making it one of the most excavated Pitted Ware Culture sites in Sweden. LÄS MER
