  1. 1. Design av hållbara parkeringar – material, växtval och ekosystemtjänster

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Jacob Persson; Martin Toft Möllerberg; [2023]
    Keywords : parkeringar; hållbarhet; uppbyggnad; uppbyggnad; växtval; urbana värmeöar; transformation; permeabelt; ekosystemtjänster; dagvattenhantering; BGG-system; upplevelsevärden;

    Abstract : Under vår utbildning för att bli Landskapsarkitekter har vi identifierat förbättringspotential för parkeringar generellt. De har ofta döende vegetation, saknar permeabla ytor och har suboptimal utformning. READ MORE

  3. 2. Reconstruction of Fire Spread with a Markov Random Field Mixture Model

    University essay from Lunds universitet/Matematisk statistik

    Author : Marcus Gehrmann; [2023]
    Keywords : Forest fire; fire scars; spatial statistics; Markov random field; EM-algorithm; pseudo-likelihood; Mathematics and Statistics;

    Abstract : This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively.

  4. 3. Estimation of severe crash frequency using two surrogates

    University essay from Lunds universitet/Matematisk statistik

    Author : Zhankun Chen; [2022]
    Keywords : Multivariate Extreme Value distributions; Copula; Extreme Value Theory; Crash frequency; Surrogate Meausre of Safety; Road safety; Mathematics and Statistics;

    Abstract : This thesis is concerned with the estimation of crash frequency based on the bivariate modeling of surrogate measures of safety (SMoS), which serve as indicators for traffic risk. Using the SMoS, any traffic conflict between two road users can be described by their proximity together with their hypothetical consequence. READ MORE

  5. 4. Analyzing the Negative Log-Likelihood Loss in Generative Modeling

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

    Author : Aleix Espuña I Fontcuberta; [2022]
    Keywords : Generative modeling; Normalizing flows; Generative Adversarial Networks; MaximumLikelihood Estimation; Real Non-Volume Preserving flow; Fréchet Inception Distance; Misspecification; Generativa metoder; Normalizing flows; Generative adversarial networks; Maximum likelihood-metoden; Real non-volume preserving flow; Fréchet inception distance; felspecificerade modeller;

    Abstract : Maximum-Likelihood Estimation (MLE) is a classic model-fitting method from probability theory. However, it has been argued repeatedly that MLE is inappropriate for synthesis applications, since its priorities are at odds with important principles of human perception, and that, e.g. READ MORE

  6. 5. Gaze tracking using Recurrent Neural Networks : Hardware agnostic gaze estimation using temporal features, synthetic data and a geometric model

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

    Author : Fredrik Malmberg; [2022]
    Keywords : Gaze Tracking; Eye Tracking; Computer Vision; Transfer Learning; Synthetic Data; Domain Adaptation; Sequential Models; Blickspårning; Ögonspårning; Datorseende; Transfer Learning; Syntetisk Data; Domain Adaptation; Sekventiella Modeller;

    Abstract : Vision is an important tool for us humans and significant effort has been put into creating solutions that let us measure how we use it. Most common among the techniques to measure gaze direction is to use specialised hardware such as infrared eye trackers. READ MORE
