  1. 1. A comparative study on the unsupervised classification of rat neurons by their morphology

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

    Author : Sabrina Chowdhury; Added Kina; [2020]
    Keywords : ;

    Abstract : An ongoing problem regarding the automatic classification of neurons by their morphology is the lack of consensus between experts on neuron types. Unsupervised clustering using persistent homology as a descriptor for the morphology of neurons helps tackle the problem of bias in feature selection and has the potential of aiding neuroscience research in developing a framework for automatic neuron classification.

  2. 2. Behaviour and morphology in wild guppies from populations with high and low predation pressure in Trinidad

    University essay from SLU/Dept. Of Aquatic Resources

    Author : William Harry Ashworth; [2020]
    Keywords : behavioural ecology; colouration; Poecilia reticulata; sexual ornament;

    Abstract : Behaviour and morphology can vary significantly within a species as a result of the predation pressure individuals are exposed to. Wild populations of guppies (Poecilia reticulata) exposed to high and low predation can be found in the streams of northern Trinidad, providing a useful study system for investigating how behaviour and morphology are affected by predation.

  3. 3. Analyzing the scalability of R*-tree regarding the neuron touch detection task

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

    Author : Anton Brask; Filip Berendt; [2020]
    Keywords : ;

    Abstract : A common task within research of neuronal morphology is neuron touch detection, that is finding the points in space where two neurites approach each other to form a synapse. In order to make efficient use of cache memory, it is important to store points that are close in space close in memory. READ MORE

  4. 4. Smoltification status of Atlantic salmon (Salmo salar) in relation to migratory success and migration speed in a regulated river

    University essay from Karlstads universitet

    Author : Johanna Högvall; [2020]
    Keywords : Atlantic salmon; juvenile downstream migration; parr-smolt transformation; regulated rivers; dams; migration delay; radio-telemetry; Atlantlax; vandringshinder; smoltifieringsgrad; reglerade älvar; radiotelemetri;

    Abstract : There is a concern that the ecosystems around the world are suffering from fragmentation. Ecosystems such as rivers have lost their connectivity to a large extent due to hydroelectric dams with no or insufficient passways for the natural flow of organisms, matter and energy. READ MORE

  5. 5. Automatic morphological analysis of L-verbs in Palula

    University essay from Stockholms universitet/Institutionen för lingvistik

    Author : Emma Wallerö; [2020]
    Keywords : Finite-State Transducer; FST; morphology; two-level morphology; machine learning; Sequence to Sequence; RNN; Finite-State Transducer; FST; morfologi; tvånivåmorfologi; maskininlärning; Sequence to Sequence; RNN;

    Abstract : This study is exploring the possibilities of automatic morphological analysis of L-verbs in the Palula language by the help from Finite-state technology and two-level morphology along with supervised machine learning. The type of machine learning used are neural Sequence to Sequence models. READ MORE
