  1. 1. Basal Area Growth and Yield Models for Siberian Larch

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Alfred Deutgen; [2023]
    Nyckelord :Growth model; Yield model; Siberian Larch; Russian larch; Larix sibirica; Larix sukaczewii; Lundqvist-korf model; Mixed effect model;

    Sammanfattning : There is no species-specific basal area growth model for Siberian Larch in Sweden, which is necessary in evaluating forest management decisions. Three different models were created from stand trials around Sweden. LÄS MER

  3. 2. Effect of tree age on masting signal in tree-ring chronologies of beech in southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Jeppe Van Der Lee; [2023]
    Nyckelord :beech; masting; masting signal; proxy; tree-ring chronologies; age; dominance; social position; southern Sweden; climate change; tree growth; regeneration success;

    Sammanfattning : Masting is a synchronous and highly variable production of seeds in tree species. Masting may reflect a reproduction strategy to cope with seed predation. In beech, temperature is the cue controlling annual variability in seeding. Masting behaviour in beech typically begins around the age of 40 years. LÄS MER

  4. 3. System level analysis of Immune system in children with solid tumors

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Science for Life Laboratory, SciLifeLab

    Författare :Nadia Hassan Shamas; [2022]
    Nyckelord :Immune system in Children; Cancer; Medicines;

    Sammanfattning : Over the last few years, significant immune system changes have been observed in tumor patients exposed to different treatments. Moreover, evaluation and prediction of the responses of treatments given to these patients can become a key component. LÄS MER

  5. 4. Modeling COPD with a Generalized Linear Mixed Effect Model : Results from the OLIN-study

    Magister-uppsats, Umeå universitet/Statistik

    Författare :Jenny Sjödin; [2022]
    Nyckelord :;

    Sammanfattning : The purpose of this thesis is to analyze which factors are associated with physicians’ diagnosis of Chronic Obstructive Pulmonary Disease (COPD) where time is of primary interest. The data that is used in the analysis is from the OLIN studies. LÄS MER

  7. 5. Development of artificial neural networks for the prediction of outlying and influential individuals from pharmacokinetic and pharmacodynamic models

    Master-uppsats, Uppsala universitet/Institutionen för farmaci

    Författare :Osama Qutishat; [2022]
    Nyckelord :Machine learning; pharmacometrics; Neural networks; pop-pk;

    Sammanfattning : Nonlinear Mixed effect models are often used to describe population pharmacokinetics (PK) and Pharmacodynamics (PD) and play an important part of drug development both from regulatory and industry point of view. However, they can be time consuming and computationally expensive to develop. LÄS MER
