  1. 1. A Framework for Fatigue Analysis of Carbon Fiber Reinforced Polymer Structures

    Författare :Sara Eliasson; Zuheir Barsoum; Per Wennhage; Kim Branner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heavy-duty vehicles; Fatigue; Carbon fiber reinforced polymer; Multi-scale modeling; Probabilistic modeling; Tunga fordon; Utmattning; Kolfiberkomposit; Probabilistisk modellering; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Our society depends on functional road communication, and Heavy Duty Vehicles (HDVs) offer convenient and limitless possibilities of transport and services. However, HDVs account for a quarter of the European Union's CO2 road emissions. There is a substantial need to reduce the CO2 emissions of HDVs to ensure a low negative environmental impact. LÄS MER

  3. 2. Breaking the Dimensionality Curse of Voronoi Tessellations

    Författare :Vladislav Polianskii; Florian T. Pokorny; Michael Bronstein; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geometric methods; machine learning methods; Voronoi; Delaunay; high dimensional geometry; curse of dimensionality; monte carlo; Datalogi; Computer Science;

    Sammanfattning : Considering the broadness of the area of artificial intelligence, interpretations of the underlying methodologies can be commonly narrowed down to either a probabilistic or a geometric point of view. Such separation is especially prevalent in more classical "pre-neural-network" machine learning if one compares Bayesian modelling with more deterministic models like nearest neighbors. LÄS MER

  4. 3. Fatigue of existing steel bridges : Reliability and risk analyses for decision-making

    Författare :Ruoqi Wang; John Leander; Raid Karoumi; Boulent Imam; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; steel bridges; decision-making; reliability analysis; risk analysis; spatial correlation; system modelling; inspection and maintenance; Utmattning; stålbroar; beslutsfattande; tillförlitlighet; riskanalys; rumslig korrelation; systemmodellering; inspektion och underhåll; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Fatigue is one of the primary reasons that limit the service life of steel bridges. Many bridges in Sweden and other countries have progressively approached their anticipated service lives. Since funding and resources are limited, simultaneously replacement or maintenance of bridges is impractical. LÄS MER

  5. 4. Computational methods for analysis of spatial transcriptomics data : An exploration of the spatial gene expression landscape

    Författare :Alma Andersson; Joakim Lundeberg; Omer Bayraktar; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spatial transcriptomics; machine learning; data analysis; RNA-seq; probabilistic; statistical; models; Biotechnology; Bioteknologi;

    Sammanfattning : Transcriptomics techniques, whether in the form of bulk, single cell/nuclei, or spatial methods have fueled a substantial expansion of our knowledge about the biological systems within and around us. In addition, the rate of innovation has accelerated over the last decade, resulting in a multitude of technological advances and new methods for generation of transcriptomics data. LÄS MER
