  1. 1. Nanoparticle synthesis analysis : Program for data visualization and cluster analysis of nanoparticle synthesis protocols

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Emil Juviken Hultman; Jacob Signeul; Lucas Lindborg; Eskil Silfur; [2023]
    Nyckelord :Dataanalysverktyg;

    Sammanfattning : As energy demands rise across the globe, new clean energy solutions must be developed. Peafowl Plasmonics is developing a direct solar harvesting device using plasmonic technology. To expand their business and increase manufacturing scalability, nanoparticle synthesis protocols must be made. LÄS MER

  3. 2. Klustring för Oceanografiska Mätningar i Östersjön

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Filip Derksen; Olof Woxenius; [2023]
    Nyckelord :Spectral clustering; Oceanography; Baltic Sea;

    Sammanfattning : Målet med denna studie var att undersöka inverkan av brus, normaliseringen av Laplacianen, antalet kluster k och antalet grannar i närhetsgrafen knn på en implementation av spektral klustring. Med hjälp av den framtagna klustringen skulle lämpligheten att använda spektral klustring i en oceanografisk tillämpning utvärderas. LÄS MER

  4. 3. Use of Satellite Remote Sensing for Detecting Archaeological Features: An Example from Ancient Corinth, Greece

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Emmanouil Papadakis; [2023]
    Nyckelord :Geography; GIS; Satellite Remote Sensing; Vegetation Indices; Classification; Archaeology; Earth and Environmental Sciences;

    Sammanfattning : During the last few decades, satellite remote sensing has proven to be an important non-invasive method for archaeological research in order to detect ancient sites and manage existing ones. Archaeologists have tried in the recent past to embed Geographic Information Systems (GIS) and image processing techniques in their research as non-destructive approaches, which can allow a wider perception of archaeological landscapes and predict past behaviors.

  5. 4. Real-Time Continuous Euclidean Distance Fields for Large Indoor Environments

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

    Författare :Erik Warberg; [2023]
    Nyckelord :Room segmentation; Gaussian processes; Euclidean distance fields; mapping; line segment detection; mobile robots; spectral clustering; Rumssegmentering; Gaussiska processer; Euklidiska avståndsfält; kartläggning; detektering av linjesegment; mobila robotar; spektral klustring;

    Sammanfattning : Real-time spatial awareness is essential in areas such as robotics and autonomous navigation. However, as environments expand and become increasingly complex, maintaining both a low computational load and high mapping accuracy remains a significant challenge. LÄS MER

  7. 5. Computing Equivalent hydropower models in Sweden using inflow clustering

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

    Författare :Daniel Lilja; [2023]
    Nyckelord :Hydropower; Equivalent; Bilevel; Optimization; Clustering; Inflow; Sweden; Vattenkraft; Ekvivalent; Bilevel; Optimering; Klusteranalys; Inflöde; Sverige;

    Sammanfattning : To simulate a hydropower system, one can use what is known as a Detailed model. However, due to the complexity of river systems, this is often a computationally heavy task. Equivalent models, which aim to reproduce the result of a Detailed model, are used to significantly reduce the computation time for these simulations. LÄS MER
