1. 6. Spatial analysis of urban housing stocks

   Författare :Magnus Österbring; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy performance certificate; Building-stock modelling; GIS; renovation; refurbishment; Energy; Multi-family buildings;

   Sammanfattning : Urban building-stocks must be transformed in order to reduce energy and resource use to achieve climate change mitigation targets. As the rate of renewal in the building-stock is low, energy efficiency measures need to be applied when renovation is being done. LÄS MER

3. 7. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

   Författare :Gyözö Jordan; Ulf Qvarfort; Tsehaie Woldai; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; Miljöteknik;

   Sammanfattning : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. LÄS MER

4. 8. Ontology as Conceptual Schema when Modelling Historical Maps for Database Storage

   Författare :Gustaf Svedjemo; Erland Jungert; Wollter Arnberg; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; ontology; historical maps; database modelling; GIS; Geographical Information Systems; archaeology; history; ontologi; historiska kartor; databasmodellering; GIS; geografiska informationssystem; arkeologi; historia; Computer science; Datavetenskap; History subjects; Historieämnen;

   Sammanfattning : Sweden has an enormous treasure in its vast number of large-scale historical maps from a period of 400 years made for different purposes, that we call map series. The maps are also very time and regional dependent with respect to their concepts. A large scanning project by Lantmäteriverket will make most of these maps available as raster images. LÄS MER

5. 9. Visualization, integration and analysis of multi-element geochemical data

   Författare :Katrin Grünfeld; Herbert Henkel; Olle Selinus; Reijo Salminen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; GIS; interactive visualization; glacial till; biogeochemistry; metals; southeastern Sweden; Geovetenskap; Earth sciences; Geovetenskap;

   Sammanfattning : generated large databases containing information on the concentrations of chemical elements in rocks, surface sediments and biogeochemical materials. Regional geochemical data being imprecise, multivariate, spatially auto-correlated and non-normally distributed pose specific problems to the choice of data analysis methods. LÄS MER

7. 10. A comprehensive approach to building-stock modelling - Assessing the impact of renovating urban housing stocks

   Författare :Magnus Österbring; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy performance certificate; costeffectiveness; GIS; LCA; building valuation; renovation; refurbishment; Building-stock modelling; multi-family buildings; energy;

   Sammanfattning : The existing building stock provide a possibility for cost-efficient energy efficiency measures and related reductions in greenhouse-gas emissions. As the rate of renewal in the buildingstock is low, energy efficiency measures need to be applied when renovation is being done in order to reach climate goals. LÄS MER
