  1. 1. The definition of fens and bogs : An international meta-study

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Zakaria Hachicho; [2023]
    Keywords : fens; bogs; fen; bog; peatland; peatlands; mire; mires; classification; definition; kärr; mosse; torvmark; myr; klassificering; definition;

    Abstract : Disagreements on how fens and bogs are defined warrants an evaluation of how researchers classify these habitats. Ongoing work with a new typology for ecosystems creates an urgency to understand the classification in the field. READ MORE

  3. 2. Towards Automatic Model Atoms from the VALD Atomic Database: from He to U

    University essay from Uppsala universitet/Teoretisk astrofysik

    Author : Samuel Hermansson; [2023]
    Keywords : r-process; nucleosynthesis; kilonovae; VALD;

    Abstract : The ejecta following the collision and merging of two neutron stars (kilonova) are currently considered promising sites for nucleosynthesis of r-process elements. Since the observed kilonova in 2017, GW2017817, astrophysicists have been working to analyze the collected electromagnetic spectra, trying to identify r-process elements. READ MORE

  4. 3. Characterization of discrepancies between manual and automatic segmentation to improve anatomical brain atlases

    University essay from

    Author : Anna Sörensson; [2021-05-10]
    Keywords : Medical physics; Anatomical brain atlas; Image segmentation; Image registration;

    Abstract : Purpose: To characterize discrepancies between expert manually segmented brain images from Hammers Atlas Database and automatically generated segmentations of the same images; to decide whether they can be attributed to flaws in the automatic segmentation or in the manual segmentation; and to determine general rules that enable these decisions. Theory: Image segmentation plays an important role in clinical neuroscience and experimental medicine for extraction of information from medical images, and it is a fundamental image processing step in medical image analysis.

    Abstract : The task to implement a solution of handling updates and version discrepancies within a testbeds Configuration Management. The Ericsson 5G testbed is built to support deployment of higher layer functions in a cloud environment. READ MORE

  6. 5. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lotte Wendt; [2021]
    Keywords : active layer thickness; DInSAR; subsidence; permafrost; Zackenberg; CALM; Earth and Environmental Sciences;

    Abstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.
