  1. 1. A computational model of metapopulation dynamics and organism-mediated nutrient flow

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Amanda Hansson; [2023-08-07]
    Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

    Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.

  3. 2. Vibroacoustic Analysis of an OLTC Diverter Switch for Condition Monitoring : Time frequency analysis with Fourier and wavelet transform in combination with multivariate logistic regression for condition monitoring of OLTC diverter switch

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Simon Persson; [2023]
    Keywords : Wavelet transform; CWT; logistic regression; machine learning; ML; vibroacoustic analysis; time frequency analysis; tap changer; diverter switch; power transformer; classification; prediction; condition; vibrations; state prediction; Hitachi Energy;

    Abstract : Vibrations are everywhere around us all the time and we often recognise them as sounds that we can hear and analyse with our brain. In this thesis, data that has been gathered from a diverter switch (DS) in a controlled environment, is analysed. READ MORE

  4. 3. Behavior and Performance of Some Inference Tools in Beta Regression

    University essay from Uppsala universitet/Geometri och fysik

    Author : Max Raner; [2022]
    Keywords : ;

    Abstract : Finite interval data, such as proportions, concentrations or rates, often exhibits asymmetryand heteroscedasticy in a regression setting, which can cause issues when tryingto model such data using common modelling approaches. Ferrari and Cribari-Neto, 2004 proposed a modeling approach similar to a generalized linear model, inwhich the response is assumed to be beta distributed, using an alternative parameterisationin terms of a mean and a precision parameter, and then modeled via a linkfunction depending on a linear predictor.

  5. 4. Landslide Susceptibility Analysis Using Open Geo-spatial Data and Frequency Ratio Technique

    University essay from KTH/Geoinformatik

    Author : TARIK EMRE YORULMAZ; [2022]
    Keywords : Landslides; Hazard mapping; Geographic Information Systems GIS ; Spatial analysis; Frequency ratio FR ; Area Under a Curve AUC ;

    Abstract : Landslide susceptibility maps are useful for spatial decision-making to minimize the lossof lives and properties. There are many studies related to the development of landslidesusceptibility maps using various methods such as Analytic Hierarchy Process, Weight ofEvidence and Logistic Regression. READ MORE

  6. 5. A practical framework for the electric vehicle routing problem

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Johan Hellmark; [2022]
    Keywords : Technology and Engineering;

    Abstract : The routing of a delivery fleet is a classical optimization problem, known as the vehicle routing problem (VRP), which can heavily impact the quality of a logistic distribution process. Historically, the VRP formulation has mainly included internal combustion engine vehicles (ICEVs). READ MORE
