1. 1. Plant-soil feedbacks in boreal tree species

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

   Author : Kailey Tentis; [2023]
   Keywords : plant-soil feedback; plant economic spectrum; biotic feedback; abiotic feedback; sterilization-inoculation experiment; conspecifics and heterospecifics;

   Abstract : Plant-soil feedback (PSF) is important for understanding how plants influence the composition and abundance of soil biota and nutrients and how this affects plant growth. The plant economic spectrum (PES) also plays a role. READ MORE

3. 2. Parallelising High OrderTransform of Point SpreadFunction and TemplateSubtraction for AstronomicImage Subtraction : The implementation of BACH

   University essay from Linköpings universitet/Informationskodning

   Author : Annie Wång; Victor Lells; [2023]
   Keywords : Image Subtraction; HOTPANTS; SFFT; GPU; Parallelisation;

   Abstract : This thesis explores possible improvements, using parallel computing, to the PSF-alignment and image subtraction algorithm found in HOTPANTS. In time-domain astronomy the PSF-alignment and image subtraction algorithm OIS is used to identify transient events. READ MORE

4. 3. “Fluffy stuff decides the game” : A multiple case study exploring utility of DCTs andstrategic choice of language in the internationalisation process

   University essay from Jönköping University/IHH, Företagsekonomi

   Author : Ellen Gustavsson; Sernelin Ahlsén Sandra; [2023]
   Keywords : Internationalisation Process; Professional Service Firms; Digital Communication Tools; Language;

   Abstract : Background: Professional services firms (PSFs) face unique challenges when internationalisingdue to their intangible services and the need to adapt to local markets. Digital technologies havemade internationalisation more efficient since firms utilise digital communication tools (DCTs). READ MORE

5. 4. Search for transiting exoplanets in globular clusters

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Oskar Nilsson; [2023]
   Keywords : Physics and Astronomy;

   Abstract : This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. READ MORE

6. 5. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

   University essay from

   Author : Ali Amena Hussain; [2022-03-09]
   Keywords : Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

   Abstract : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.
