    University essay from KTH/Matematisk statistik

    Author : Björn Johansson; [2020]
    Keywords : Ordinary Kriging; Variograms; Geostatistics; Statistical Methods; Ordinary Kriging; Variogram; Geostatistik; Statistiska Metoder;

    Abstract : In modern mining industry, new resource efficient and climate resilient methods have been gaining traction. Commissioned efforts to improve the efficiency of European mining is further helping us to such goals. Orexplore AB's X-ray technology for analyzing drill cores is currently involved in two such project. READ MORE

  3. 2. Evaluating spatial mapping using interpolation techniques

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Allan Gholmi; [2017]
    Keywords : ;

    Abstract : In this thesis, the inverse distance weighting, different kriging methods, ordinary least squares and two variants of the geographically weighted regression was used to evaluate the spatial mapping abilities on an observed dataset and a simulated dataset. The two datasets contain the same bioclimatic variable, near-surface air temperature, uniformly distributed over the whole world. READ MORE

  4. 3. The spatial distribution of birds in southern Sweden : A descriptive study of willow warbler, nightingale, blackbird, robin and grey flycatcher in Svealand and Götaland.

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Lars Sjöström; [2016]
    Keywords : Poisson regression; Kriging; Variogram; Spatial correlation; Temporal correlation; Geostatistics; Biostatistics; Landscape Ecology;

    Abstract : This is a thesis about the spatial distribution of willow warbler, nightingale, blackbird, robin and grey flycatcher in Svealand and Götaland, that is the southern third of Sweden. It explores the possibilities of using statistics to describe the distribution and variation of birds in a given region. READ MORE

  5. 4. The significance of heterogeneity for spreading of geologically stored carbon dioxide

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Christofer Olofsson; [2011]
    Keywords : Storage efficiency; Heterogeneity; Variogram; iTOUGH2; ECO2N; Geological storage; CO2; Saline aquifer; Lagringseffektivitet; Heterogenitet; Variogram; iTOUGH2; ECO2N; Geologisk lagring; CO2; Saltvattenakvifär;

    Abstract : The demand for large scale storage of carbon dioxide (CO2) grows stronger as incentives to reduce greenhouse gas emissions are introduced. Geological storage sites such as depleted oil and gas reservoirs, unminable coal seams and deep saline water-saturated aquifers are a few of many possible geological storage sites. READ MORE

  6. 5. 3D modeling in Petrel of geological CO2 storage site

    University essay from Institutionen för geovetenskaper

    Author : Niklas Gunnarsson; [2011]
    Keywords : CO2 sequestration; Petrel; Sequential Gaussian simulation; Truncated Gaussian simulation; Sequential indicator simulation; Porosity modeling; Facies modeling; Variogram analysis; South Scania site; CO2 lagring; Petrel; Sekventiell Gaussisk simulering; Trunkerad Gaussisk simulering; Sekventiell indikator simulering; Porositetsmodellering; Faciesmodellering; Variogramanalys; Sydvästra Skåne;

    Abstract : If mitigation measures are not made to prevent global warming the consequences of a continued global climate change, caused by the use of fossil fuels, may be severe. Carbon Capture and Storage (CCS) has been suggested as a way of decreasing the global atmospheric emission of CO2. READ MORE
