  2. 1. Classification of Remotely Sensed Data Utilising the Autocorrelation between Spatio-Temporal Neighbours

    Author : Ann-Marie Flygare; Sweden Umeå Umeå University Department of Mathematical Statistics; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image classification; strong mixing; spatio-temporal model; autocorrelation model; autocorrelation estimator; robustness aspects; strong consistency; asymptotic normality; evaluation; Statistik; Statistics;

    Abstract : The subject of this thesis is methods for classifying land using satellite images, and adherent parameter estimation. A satellite image consists of a set of pixels where measurements of spectral intensities are observed. Based on these spectral intensities, each pixel is assigned a class. READ MORE

  5. 3. Movement patterns and displacement of a soil insect

    Author : Elna Nilsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; attraction; repellence; fatty acid; Ecology; Ekologi; alarm; autoregressive model; autocorrelation; random walk; Protaphorura armata; Collembola; migration; dispersal; movement; displacement;

    Abstract : Movement and dispersal are important determinants of the spatial distribution and persistence of animal populations in a heterogeneous environment. I studied the small-scale movement pattern of a soil-living insect, Protaphorura armata (Collembola) by using a video-equipment. READ MORE

  6. 4. Population and Community Dynamics in Variable Environments

    Author : Jörgen Ripa; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dispersal; Moran effect; linear dynamics; synchrony; power spectrum; autocorrelation; extinction risk; population dynamics; environmental stochasticity; migration; stochastic modelling; Ecology; Ekologi;

    Abstract : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. READ MORE

  7. 5. Quantitative microscopy of coating uniformity

    Author : Christina Dahlström; Tetsu Uesaka; Magnus Norgren; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating uniformity; coating microstructure uniformity; base sheet effects; argon ion beam milling; scanning electron microscopy; image analysis; binder distributions; autocorrelation analysis; random deposition process; simulation;

    Abstract : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.
