  1. 6. On flexible random field models for spatial statistics: Spatial mixture models and deformed SPDE models

    Author : Anders Hildeman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spatial statistics; Significant wave height; Spatial mixture model; Stochastic partial differential equation; Log-Gaussian Cox process; Point process; Gaussian random field; Substitute-CT;

    Abstract : Spatial random fields are one of the key concepts in statistical analysis of spatial data. The random field explains the spatial dependency and serves the purpose of regularizing interpolation of measured values or to act as an explanatory model. READ MORE

  2. 7. Multi-robot Information Fusion : Considering spatial uncertainty models

    Author : Lars Andersson; Karl-Erik Rydberg; Aarne Halme; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The work presented in this thesis covers the topic of deployment for mobile robot teams. By connecting robots in teams they can perform a better job than each individual is capable of. It also gives redundancy, increases robustness, provides scalability, and increases efficiency. READ MORE

  3. 8. Spatial Models of Gene Patterns in Plants

    Author : André Larsson; Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; []
    Keywords : computational morphodynamics; gene regulation; spatial models; plants; development; auxin; meristem; Fysicumarkivet A:2017:Larsson;

    Abstract : The growth and development of plants exhibits a striking symmetry, visible in the regular arrangement of leaves and flowers. Plant development is carefully controlled at the molecular level by gene regulatory networks, and the symmetry of plants can be observed also in the molecular patterns of gene expression. READ MORE

  4. 9. Spatial Mixture Models with Applications in Medical Imaging and Spatial Point Processes

    Author : Anders Hildeman; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Non-Gaussian; Bayesian level set inversion; Point processes; Substitute CT; Finite mixture models; Spatial statistics; Gaussian fields; Non-Gaussian;

    Abstract : Finite mixture models have proven to be a great tool for both modeling non-standard probability distributions and for classification problems (using the latent variable interpretation). In this thesis we are building spatial models by incorporating spatially dependent categorical latent random fields in a hierarchical manner similar to that of finite mixture models. READ MORE

  5. 10. Computational Models of Spatial Transcriptomes

    Author : Ludvig Bergenstråhle; Joakim Lundeberg; Jens Lagergren; Ole Winther; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknologi;

    Abstract : Spatial biology is a rapidly growing field that has seen tremendous progress over the last decade. We are now able to measure how the morphology, genome, transcriptome, and proteome of a tissue vary across space. READ MORE
