  1. 1. The effect of autocorrelation when performing theapproximated permutation test

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Amerik Schouten; Linus Thor; [2023]
    Keywords : exchangeability assumption; Monte Carlo; temporal autocorrelation; type I error; simulation; re-sampling methods;

    Abstract : In meteorology, permutation tests are a commonly recommended tool because standard paramet-ric methods of inference often is insufficient when analysing weather. Therefore other methodswith less stringent assumptions like permutation testing is used. READ MORE

  3. 2. Multi-scale Bark Beetle Predictions Using Machine Learning

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Albert Øhrman Wellendorf; [2023]
    Keywords : Geography; GIS; Geographically weighted regression; bark beetle; machine learning; Earth and Environmental Sciences;

    Abstract : Bark beetle attacks have led to widespread tree disturbance and deaths in many parts of the world, and thereby also economic and biodiversity losses. Forest-rich Sweden has experienced periodic attacks, latest in 2018. READ MORE

  4. 3. Mapping wetlands in Sweden using multi-source satellite data and random forest algorithm

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Salvador Hernandez Malave; [2022]
    Keywords : physical geography and ecosystem analysis; multi-temporal; Google Earth Engine; machine learning; classification; country-wide; geomatics; Earth and Environmental Sciences;

    Abstract : Wetlands are valuable ecosystems, and assets for human life, that must be regularly monitored, starting with accurately mapping their location and extent. However, an updated national inventory of wetlands is needed. READ MORE

  5. 4. Diffuse correlation spectroscopy for estimation of coagulation thickness : a phantom study

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Zeyneb Alsadi; [2019]
    Keywords : DCS; Diffuse correlation spectroscopy; Biomedical optics; coagulation; phantom study; coagulation depth; coagulation thickness; diffusion; model; two layer model;

    Abstract : The objective of this preliminary study was to determine the potential of diffuse correlation spectroscopy (DCS) for assessment of coagulation depth. Coagulation of tissue can occur due to a number of different reasons such as thermal or electrical burns or radiofrequency ablation. READ MORE

  6. 5. Temporal Characterization and Intensity Contrast Improvement of Few-cycle Laser Pulses

    University essay from Umeå universitet/Institutionen för fysik

    Author : Xiaoying Zhang; [2019]
    Keywords : ;

    Abstract : Due to the unique combination of properties of high intensity and few optical cycle pulse duration, the ultrashort laser pulses have widespread applications in pump-probe spectroscopy and laser-plasma interaction. Correspondingly, it is critical to precisely measure the electric field in the temporal or spectral domain. READ MORE
