  1. 1. 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

  3. 2. Augmented Reality for Immersive Video Conference Presentations : Enhancing Video Presentation Experiences with Visual Aid Through Augmented Reality

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gabriel Rosenberg; [2023]
    Nyckelord :Extended Reality; Augmented Reality; Video Conferencing; Computer Vision; Natural Interaction; Natural User Interfaces; Förstärkt verklighet; videokonferenser; datorseende; naturlig interaktion; naturliga gränssnitt;

    Sammanfattning : As 3D models are increasingly used in a variety of contexts, both for entertainment in games and movies, as well as professional visualization and CAD models, there is an increased demand for collaborative tools which can be used to show these virtual artifacts efficiently. Interaction with digital 3D artifacts has long since been enabled through the use of specialized software, like CAD modeling applications and 3D rendering software; which often are extensive and require time to master and use efficiently.

  4. 3. Credit Index Forecasting: Stability of an Autoregressive Model

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Melker Wallén; Erik Grimlund; [2023]
    Nyckelord :Credit spreads; Time Series; Credit Risk; Index Modeling; Forecasting; Kreditspreadar; Tidsserier; Kreditrisk; Indexmodellering; Prognoser;

    Sammanfattning : This thesis investigates the robustness and stability of total return series for credit bond index investments. Dueto the challenges which arise for financial institutes and investors in achieving these objectives, we aim to createa forecasting model which matches the statistical properties of historical data, while remaining robust, stable andeasy to calibrate.

  5. 4. Analytiska modeller för beräkning av tjällaster mot spontkonstruktioner

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :STAFFAN NORRTHON RISBERG; NAIMA OZIMS; [2023]
    Nyckelord :;

    Sammanfattning : I kalla klimat kan stödkonstruktioner utsättas för lastökningar till följd av tjälande jord. Tjälen bildas när vattnet i jorden fryser, och leder ofta till en volymexpansion i marken. Om tjälexpansionen förhindras bildas ett tjältryck, som kan bli så pass kraftigt att stödkonstruktioner riskerar att gå till brott. LÄS MER

  7. 5. Investigating the response of terrestrial evapotranspiration to droughts in Africa : A combined remote sensing and modeling approach

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Yang Foo; [2023]
    Nyckelord :earth observation; terrestrial evapotranspiration; drought; vegetation-climate interactions;

    Sammanfattning : Climate change is posing a significant threat to terrestrial ecosystems worldwide, in part due to the more frequent occurrence of extreme climatic events such as droughts. While the importance of drought impacts on vegetation has been widely recognized, the time-dependent characteristics of drought-induced response remain insufficiently understood. LÄS MER
