  1. 1. Convolutional neural network based object detection in a fish ladder : Positional and class imbalance problems using YOLOv3

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

    Author : Patrik Ekman; [2021]
    Keywords : Object detection; Computer vision; Fish ladder; Imbalance problems; Imbalanced data; YOLO; Convolutional Neural Network; Deep learning; Objektdetektering; Datorseende; Fisktrappa; Obalanser; Obalanserad data; YOLO; Convolutional Neural Network; Djupinl¨arning;

    Abstract : Hydropower plants create blockages in fish migration routes. Fish ladders can serve as alternative routes but are complex to install and follow up to help adapt and develop them further. In this study, computer vision tools are considered in this regard. READ MORE

  3. 2. Fjärranalysstödd objektiv uppskattning av virkesförråd för värdering av fastigheter

    University essay from SLU/Dept. of Forest Resource Management

    Author : Anton Romlin Fredriksson; [2016]
    Keywords : fjärranalys; fastighetsvärdering; balanserad sampling;

    Abstract : Att värdera fastigheter kräver en noggrann uppfattning om virkesförrådet på fastigheten i fråga, detta för att kunna skapa bra och tillförlitliga värderingar. Det har under de senaste årtiondena pågått stora avancemang inom fjärranalysområdet både tekniskt och kunskapsmässigt. READ MORE

  4. 3. Calibration and Application of Passive Sampling in Drinking Water for Perfluoroalkyl Substances

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Caroline Persson; [2015]
    Keywords : Perfluoroalkyl substances PFASs ; passive sampling; Polar organic compound integrative sampler POCIS ; sampling rate; calibration; application; drinking water; Perfluoroalkylsubstanser PFAS ; passiv provtagning; Polar organic compound integrative sampler POCIS ; provtagningsshastighet; kalibrering; tillämpning;

    Abstract : Perfluoroalkyl substances (PFASs) are global environmental contaminants and a need for monitoring levels has arisen due to their persistency and their ability to bioaccumulate. One relatively novel method of monitoring for both long and short time intervals and generating time-weighted average (TWA) concentrations is passive sampling for which no power, maintenance and supervision is required.
