1. 16. Modeling Width in Spatial Optimization in Raster Space

   Författare :Lindsi Seegmiller; Takeshi Shirabe; Lars Harrie; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; raster-based geographic information system; spatial optimization; region selection; width; optimal routing; raster data modeling; distortion; corridor; rasterbaserat geografiskt informationssystem; rumslig optimering; regionval; bredd; optimal routing; rasterdatamodellering; distorsion; korridor; Geoinformatik; Geoinformatics;

   Sammanfattning : Given a grid of cells, each of which is assigned a numerical value quantifying its utility (or cost) for a certain use, a popular type of problem in geographic information science is raster-based spatial optimization. Such problems commonly seek to find a set of cells that maximizes (or minimizes) that utility (or cost) while adhering to a given set of constraints. LÄS MER

   Författare :Babak Khavari; Francesco Fuso Nerini; William Usher; Mark Howells; Erik Ahlgren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

   Sammanfattning : In 2015 the United Nations (UN) General Assembly agreed on the Sustainable Development Goals (SDGs), a set of 17 goals defined by 169 targets to be reached by 2030. Amongst them is SDG 7. SDG 7 states “Ensure access to affordable, reliable, sustainable and modern energy for all”. LÄS MER

4. 18. Performance Measures of Road Infrastructure - A Life Cycle Thinking Approach

   Författare :Babak Ebrahimi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road infrastructure; Life Cycle Assessment LCA ; Lifetime Estimation; Geographic Information System GIS ; Life Cycle Thinking LCT ; Material Flow Analysis MFA ;

   Sammanfattning : Roads have been an important asset of human society and the approach we adopt towards planning, designing, constructing, operating, and maintaining of the road infrastructure has significant consequences in the long-term for not only the humans, but all species on planet Earth. Hence, the lifecycle performance of the road infrastructure that sustain our socioeconomic development with a low environmental impact, while fulfilling their technical and functional requirements is of critical importance and needs to be improved.

5. 19. Broad-Scale Patterns in CDOM and Total Organic Matter Concentrations of Inland Waters – Insights from Remote Sensing and GIS

   Författare :Enass Said Al-Kharusi; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inlandwater; Remote sensing; Sentinel-2 MSI; CDOM; GIS; climate change;

   Sammanfattning : The rise in CDOM (coloured dissloved organic matter) is likely to be relatively more pronounced in remote northern regions. However, there is a lack of monitoring to confirm this. LÄS MER

7. 20. Assessment of urban solid waste logistics systems: the case of Kampala, Uganda

   Författare :Joel Kinobe; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Many cities, especially in developing countries, are facing challenges in the management of solid waste. The aim of the study was to develop effective logistics systems for solid waste management in urban areas of developing countries, with a specific focus on Kampala, Uganda. LÄS MER
