    Abstract : Microorganisms play crucial roles in aquatic environments in determining ecosystemstability and driving the turnover of elements essential to life. Understanding thedistribution and evolution of aquatic microorganisms will help us predict how aquaticecosystems will respond to Global Change, and such understanding can be gained bystudying these processes of the past.

  4. 3. Markov chain Monte Carlo for the reconstruction of lineage trees from single-cell DNA data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Iris Balcázar Castell; [2019]
    Keywords : ;

    Abstract : The purpose of this study is to infer evolutionary trees through the Markovchain Monte Carlo algorithm (MCMC) [1] based on whole-genome single cell DNA sequencing data. By using MCMC we obtain likely tree structure samples according to the cells’ somatic point mutations in our data. READ MORE

    Author : Caroline Ivarsson; [2014]
    Keywords : 3D city model; photo-realistic; texture; reconstruction;

    Abstract : This thesis evaluates two different approaches of using panoramic street view images for creating more photo-realistic 3D city models comparing to 3D city models based on only aerial images. The thesis work has been carried out at Blom Sweden AB with the use of their software and data. READ MORE

  6. 5. Skogseldens påverkan på epifytiska trädlavar på tall i relation till brandintensiteten

    University essay from SLU/Dept. of Forest Ecology and Management
