  1. 21. Design of a drone system for maritime search and rescue missions

    University essay from KTH/Flygdynamik

    Author : Emil Pettersson; [2020]
    Keywords : Sea Rescue; Drone; Flying Wing; Blended Wing Body; SAR; Tailless; BWB; XFLR5; Search and Rescue; Drönare; Flygande Vinge; Sjöräddning; Eftersök; XFLR5;

    Abstract : The work summarized in this report aims to investigate how a drone airplane design can be optimized to create a safer and more efficient sea rescue by providing staff with an early picture, performing search missions and aiding communication through visual contact. A flying wing is in theory one of the most efficient designs for a fixed wing aircraft, at the same time as it also offers high structural efficiency for its given size. READ MORE

  2. 22. Unsupervised Deep Learning for Primitive-Based Shape Abstraction

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Vilhelm Urpi Hedbjörk; [2020]
    Keywords : deep learning; neural network; unsupervised learning; shape abstraction;

    Abstract : The ability to give simple but representative descriptions of complex shapes, known as shape abstraction, is a useful tool in computer science. An unsupervised deep neural network that predicts a set of primitive shapes to describe an arbitrary three-dimensional input shape is constructed and trained on airplane and chair models. READ MORE

  3. 23. Analysis and Initial Optimization of The Propeller Design for Small, Hybrid-Electric Propeller Aircraft

    University essay from KTH/Flygdynamik

    Author : Ali Alshahrani; [2020]
    Keywords : Electric; hybrid; Propeller; Optimization; variable pitch; fixed pitch; blades number; Eldrivet; hybrid; Propeller; Optimering; justerbar vinkel; fast vinkel; bladnummer;

    Abstract : This thesis focuses on the optimization of the electric aircraft propeller in order to increaseflight performance. Electric aircraft have limited energy, particularly the electricmotor torque compared to the fuel engine torque. For that, redesign of the propeller forelectric aircraft is important in order to improve the propeller efficiency. READ MORE

  4. 24. On the Influence of Scattering From a Power-pole on an Airport Radar

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

    Author : Ao Hu; [2019]
    Keywords : Power-pole; VOR System; Airplane; EFIE; MOM; RWG; Scattering.; Kraftstolpar; VOR Systemet; flygplan; EFIE; MoM; RWG; Spridning;

    Abstract : Power-poles are one of the common massive conducting structures in cities and countryside. To fulfill the remarkable increased electric power demand nowadays, the number and the size of power-poles are also growing over the past few decades. READ MORE

  5. 25. Visual Object Detection using Convolutional Neural Networks in a Virtual Environment

    University essay from Linköpings universitet/Datorseende

    Author : Andreas Norrstig; [2019]
    Keywords : Object Detection; Convolutional Neural Networks; Virtual Environment; Computer Vision; Deep Learning; Machine Learning;

    Abstract : Visual object detection is a popular computer vision task that has been intensively investigated using deep learning on real data. However, data from virtual environments have not received the same attention. A virtual environment enables generating data for locations that are not easily reachable for data collection, e.g. READ MORE
