  3. 12. Estimation of Red Blood Cell-Count using Neural Networks

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

    Author : David Andersson; [2020]
    Keywords : Artificial neural networks; ANN; Convolutional neural networks; CNN; Red Blood Cells; Hematology; Image analysis; Regression; Malaria; Counting; Automation; Microscopy; Physics and Astronomy;

    Abstract : Quantification through image analysis is used in a multitude of fields, and often requires algorithms tailored to the specific task and object that needs to be quantified. The need for flexibility means that such segmentation algorithms are quickly becoming outdated with the advent of convolutional neural networks, which can be trained to fit the specific requirements of the user.

  6. 15. N-body Simulations in Galactic Potentials

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : David Andersson; [2019]
    Keywords : N-body; simulation; spen clusters; dissolving time; Hyades; members of the Hyades; double integration; Physics and Astronomy;

    Abstract : What effect does a collision between two clusters have on their dissolving time? In order to answer this question, a new type of N-body simulation using a double integration of a cluster was built. Instead of introducing a perturbation representing the gravitational force of the Milky Way into a local simulation of the cluster, the cluster orbit was integrated in the potential of the Milky Way, and in each of these integration steps the local motion of the stars inside the cluster were integrated, using an N-body calculation.
