   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

3. 7. Computational methods for analysis of spatial transcriptomics data : An exploration of the spatial gene expression landscape

   Författare :Alma Andersson; Joakim Lundeberg; Omer Bayraktar; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spatial transcriptomics; machine learning; data analysis; RNA-seq; probabilistic; statistical; models; Biotechnology; Bioteknologi;

   Sammanfattning : Transcriptomics techniques, whether in the form of bulk, single cell/nuclei, or spatial methods have fueled a substantial expansion of our knowledge about the biological systems within and around us. In addition, the rate of innovation has accelerated over the last decade, resulting in a multitude of technological advances and new methods for generation of transcriptomics data. LÄS MER

4. 8. Modeling and improving Spatial Data Infrastructure (SDI)

   Författare :Ehsan Abdolmajidi; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial Data Infrastructure; System Dynamics; Fuzzy Logic; Data integration; Pattern detection; Resource Description Framework RDF ; Ontology;

   Sammanfattning : Spatial Data Infrastructure (SDI) development is widely known to be a challenging process owing to its complex and dynamic nature. Although great effort has been made to conceptually explain the complexity and dynamics of SDIs, few studies thus far have actually modeled these complexities. LÄS MER

5. 9. Spatial analysis and modeling of urban transportation networks

   Författare :Jingyi Lin; Yifang Ban; Sten Henning Hansen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex networks; transportation systems; network growth; Evolving networks; centrality; urban systems; topology; space syntax; spatial networks; distance effects; gravity laws; planarity; street network patterns; US airline system; China’s aviation system; network efficiency; cellular structure; hierarchy; network representations; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : Transport systems in general, and urban transportation systems in particular, are the backbone of a country or a city, therefore play an intrinsic role in the socio-economic development. There have been numerous studies on real transportation systems from multiple fileds, including geography, urban planning, and engineering. LÄS MER

7. 10. Heat decarbonization in municipalities - Accounting for the local spatial context in techno-economic modeling

   Författare :Hyunkyo Yu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; spatial analysis; Participatory modeling; local heat decarbonization; energy transition;

   Sammanfattning : In Europe, 57% of the energy used for space and water heating is derived from the combustion of fossil fuels, whereas only 24% comes from renewables. Compared to the wide-reaching transmission of electricity between countries, the supply of heat predominantly occurs at the local or individual level. LÄS MER
