University essay from SLU/Dept. of Ecology
Author : Beatrice Andersson; [2021]
Keywords : järv; Gulo gulo; daglega; temperatur; klimatförändring; värmereglering;
Abstract :
I Sverige har järven (Gulo gulo) under flera decennier ökat i antal vilket har bidragit till att järven har återvänt till sitt historiska utbredningsområde i södra Dalarna och norra Värmland.
Klimatförändringar tycks påverka utbredningen vilket kan leda till konsekvenser för boreala arter, till exempel järven. READ MORE

University essay from SLU/Dept. of Animal Breeding and Genetics
Author : Agnes Fridell; [2020]
Keywords : Panthera onca; Puma concolor; Bos taurus; ; Bos indicus; Pantanal; Brazil;
Abstract :
In Brazil, jaguars and pumas both constitute threats to cattle farming due to predation on calves. Since both jaguar and puma populations decline, con-flicts with humans should be avoided in order to prevent poaching, which can lead to the number of wild cats in Brazil decreasing further. READ MORE

University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation
Author : Emiel Oldenkamp; [2020]
Keywords : Mathematics; Applied Mathematics; Machine Learning; Supervised Learning; Regression; Linear Learner; Linear Regression; K-Nearest neighbors; Extreme Gradient Boosting; XGBoost; AWS SageMaker; Scania; Data Science; Data Analysis;
Abstract :
In this thesis project, we attempt to predict the stop duration of heavy vehicles using data based on GPS positions collected in a previous project. All of the training and prediction is done in AWS SageMaker, and we explore possibilities with Linear Learner, K-Nearest Neighbors and XGBoost, all of which are explained in this paper. READ MORE

University essay from Linköpings universitet/Reglerteknik
Author : Karl Gudmundson; [2019]
Keywords : Star Tracking; Celestial Navigation; Navigation Systems; Attitude; Orientation; SWIR; MEKF;
Abstract :
This work investigates the possibility of obtaining attitude estimates by capturing images of stars using a SWIR camera. Today, many autonomous systems rely on the measurements from a GPS to obtain accurate position and attitude estimates. READ MORE
