  1. 11. Anatomical segmentation of the human brain: comparative assessment of two automatic methods

    Master-uppsats,

    Författare :Carl von Dorrien; [2023-08-22]
    Nyckelord :Medical physics; MAPER; FreeSurfer; FastSurfer; Automatic brain segmentation; MRI; Deep Neural Network; Brain;

    Sammanfattning : Magnetic Resonance Imaging (MRI) is a robust and versatile imaging modality and an integral component of a lot of studies, especially when performing quantitative analysis. MRI is the preferred method of imaging the brain because of its excellent soft tissue contrast. LÄS MER

  3. 12. Structural Hybridization and Dual Roles: A Case Study of Coexisting Logics in a Government Agency

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Johanna Axelsson; Sofie Karlsson; [2023-06-29]
    Nyckelord :Institutional Logics; Coexisting Logics; Structural Hybrid; Dual Roles; Government Agency; Compartmentalization; Shieling; Segmentation;

    Sammanfattning : The area of coexisting institutional logics has been extensively discussed at the field and organizational level. However, there is currently a lack of research on the role of individual actors in creating and sustaining organizational hybrids, e.g. organizations operating under contradicting logics. LÄS MER

  4. 13. Brain morphometry in Parkinson’s disease

    Master-uppsats,

    Författare :Lönkvist Olivia; [2023-03-02]
    Nyckelord :Medical physics; Parkinson’s disease; Computational anatomy; Quantitative image analysis;

    Sammanfattning : Abstract Purpose The purpose of this brain morphometry study was to examine the volumes of different regions of the brain by research participants with Parkinson’s disease. Method To carry out the study, MR (magnetic resonance) images from 956 research participants from the Parkinson’s Progression Markers Initiative (PPMI) were used. LÄS MER

  5. 14. Utredning av leveransprecisionen hos Företag X : En analys av in- och utgående logistik, inköp och produktion

    Magister-uppsats, Linnéuniversitetet/Institutionen för management (MAN)

    Författare :Oskar Siggesson; Mattias Hedendahl; [2023]
    Nyckelord :Delivery precision; production planning; ABC XYZ-analysis; classification; cause and effect diagram; Leveransprecision; produktionsplanering; ABC XYZ-analys; klassificering; orsak och verkan-diagram;

    Sammanfattning : Background: The company has had a low outgoing delivery precision for a prolonged period. This creates problems as orders must be prioritized in order to be produced on time and partial deliveries are used to satisfy customers. The origin of the problem is unknown to the company, but there are suspicions that the problems arise in production. LÄS MER

  7. 15. Image-driven simulation of brain tumors using a reaction-diffusion mathematical model

    Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

    Författare :Kristos Qiqi; [2023]
    Nyckelord :brain tumor; cancer; mathematical model; simulation; magnetic resonance images; hjärntumör; cancer; matematisk model; simulering; magnetresonanstomografi bilder;

    Sammanfattning : Brain tumors pose a big challenge in the field of neuro-oncology. Gliomas are the largest subgroup. Magnetic resonance imaging is a non-invasive tool for detecting and characterizing these tumors. Mathematical models, such as the reaction-diffusion equation, can be used for understanding the intricate behavior of gliomas. LÄS MER
