  1. 1. A City By No-One

    Uppsats för yrkesexamina på avancerad nivå, KTH/Arkitektur

    Författare :Oscar Hultén; [2023]
    Nyckelord :urban environment interactivity algorithm;

    Sammanfattning : This project is an exploration of methods for generating virtual urban environments, framed in an interactive first-person perspective allowing the user to navigate the architectural design space by walking through a city as it is being generated. The project is developed on a foundation of three primary concepts: 1) A spatial interpretation of parameter sets which are positioned in virtual space, 2) Distance-based interpolation of these parameter sets as a method to govern how the urban environments are generated at different points in space,3) The transformation and merging of basic square grids embedded in positioned parameter sets resulting in a composite grid which functions as the spatial framework of the urban environment.

  2. 2. Spatialanalys av markgeokemi : Hur utlakningshalter av markgeokemin varierar i Sveriges morän enligt interpolationsmetoder

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Sara Emilie Hansen Österlund; [2023]
    Nyckelord :interpolations; geographic information system; GIS; geochemistry; till; geology;

    Sammanfattning : The purpose of this study was to evaluate the spatial distribution of geochemistry in Swedish till and whether interpolations could predict unknown values of geochemistry between samples at a national spatial level, Sweden, and a regional, the county of Västerbotten. The information of the spatial distribution of the elements and the interpolations accurateness has several applications. LÄS MER

  3. 3. Implementation of Super-Resolution Ultrasound Imaging for in Vitro Experiments

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Kani Yara; [2022]
    Nyckelord :B-mode; Localization; Microbubbles; Poly-Vinyl-Alcohol; Tracking; Verasonics; B-mode; Localisering; Mikrobubblor; Poly-Vinyl-Alcohol; Spårning; Verasonics;

    Sammanfattning : Ultrasound imaging systems are a safe and affordable imaging modality with the disadvantage of low spatial resolution, especially for assessing smaller vessels. However, with the implementation of super-resolution ultrasound imaging techniques, studies have shown promising results in achieving a resolution below the diffraction limit. LÄS MER

  4. 4. Modeling the Head Effect in Hydropower River Systems using MILP and BLP Approaches

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Lina Larsson; Mikaela Lindberg; [2022]
    Nyckelord :Hydropower optimization; Hydropower scheduling; The head effect; Bilinear programming; Mixed-integer linear programming;

    Sammanfattning : With a fast-growing electricity demand and a larger proportion of intermittent energy sources follows a greater need for flexible and balancing sources of electricity, such as hydropower. Planning of hydropower production is considered to be a difficult problem to solve due to several nonlinearities, combinatorial properties and the fact that it is a large scale system with spatial-temporal coupling.

  5. 5. Multivariat dataanalys och gisutvärdering av metallsammansättningen i jord

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Julie Sandberg; [2021]
    Nyckelord :;

    Sammanfattning : This report was made to evaluate the multivariate data analysis as a tool to investigate the metal composition of soil with the use of principal component analysis (PCA), and in combination with GIS interpolation. Data with several variables and observations can be difficult to analyze with only descriptive diagrams. LÄS MER
