  1. 1. Ängens potential för ekosystemtjänster i staden

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Matilda Iggström; [2023]
    Keywords : urban äng; ekosystemtjänster; urbanekologi;

    Abstract : Den rådande urbaniseringstrenden och klimatförändringar ökar behovet av ekosystemtjänster i städer. Ängen som är en av våra mest artrika marker i landskapet, trängs undan i det moderna jord- och skogsbruket, vilket hotar många ängsväxters existens. READ MORE

  3. 2. Perception of variety in forests in relation to reducing polygon count : Exploring human perception in computer graphics and computer graphics education

    University essay from KTH/Lärande

    Author : Amani Najimudeen; [2023]
    Keywords : aggregates; perception; forests; computer graphics education; aggregat; mänsklig uppfattning; skogar; datorgrafikundervisning;

    Abstract : By taking human perception into account in computer graphics, time and processing power may be utilised more efficiently when modelling and rendering scenes. Exploring possibilities for reducing the complexity of forest scenes is particularly interesting because of the geometric complexity of trees, the effects of which are compounded by dense, large-scale forests.

  4. 3. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal

    University essay from KTH/Optimeringslära och systemteori

    Author : Rasmus Maråk; [2023]
    Keywords : Spacecraft Swarms; Trajectory Optimisation; Impulsive Manoeuvres; Evolutionary Algorithms; Polyhedral Gravity Model; Small Body Exploration; Discrete Spherical Grids; Svärmande rymdfarkoster; Banoptimering; Impulsiva manövrar; Evolutionära Algoritmer; Polyhedral gravitationsmodell; Utforksning av små kroppar i solsystemet; Diskreta sfäriska rutnät;

    Abstract : Proper modelling of the gravitational fields of irregularly shaped asteroids and comets is an essential yet challenging part of any spacecraft visit and flyby to these bodies. Accurate density representations provide crucial information for proximity missions, which rely heavily on it to design safe and efficient trajectories. READ MORE

  5. 4. Deep Learning for Earth Observation: improvement of classification methods for land cover mapping : Semantic segmentation of satellite image time series

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Benjamin Carpentier; [2021]
    Keywords : Satellite Image Time Series; Remote sensing; Land Cover Classification; Deep Learning; Convolutional Neural Network; Tidsserier av satellitbilder; Fjärranalys; Classificering; Djupinlärning; KonvolutionelltNeuralt Nätverk;

    Abstract : Satellite Image Time Series (SITS) are becoming available at high spatial, spectral and temporal resolutions across the globe by the latest remote sensing sensors. These series of images can be highly valuable when exploited by classification systems to produce frequently updated and accurate land cover maps. READ MORE

  6. 5. Limit Shapes for qVolume Tilings of a Large Hexagon

    University essay from KTH/Matematik (Avd.)

    Author : Bako Ahmed; [2020]
    Keywords : Combinatorics; graph theory; orthogonal polynomials; Matematik; kombinatorik; grafteori; ortogonala polynom;

    Abstract : Lozenges are polygons constructed by gluing two equilateral triangles along an edge. We can fit lozenge pieces together to form larger polygons and given an appropriate polygon we can tile it with lozenges. Lozenge tilings of the semi-regular hexagon with sides A,B,C can be viewed as the 2D picture of a stack of cubes in a A x B x C box. READ MORE
