  1. 21. Deep Monocular Visual Odometry for fixed-winged Aircraft : Exploring Deep-VO designed for ground use in a high altitude aerial environment

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

    Author : Oliver Öhrstam Lindström; [2022]
    Keywords : Deep-VO; Aviation; Fixed-Wing; Aircraft; Deep Learning; Deep-VO; Hög Höjd; Flygplan; Deep Learning;

    Abstract : In aviation, safety is a big concern. Knowing the position of an aircraft at all times is of high importance. Today most aircraft utilize Global Navigation Satellite Systems (GNSS) for localization and precision navigation because of the small position error which do not increase over time. READ MORE

  3. 22. Thermal human detection for Search & Rescue UAVs

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Tobias Wiklund-Oinonen; [2022]
    Keywords : Mechatronics; drone; object detection; search rescue; thermal camera; UAV; SAR; YOLO; EfficientDet; TensorFlow; Mekatronik; drönare; värmekamera; räddningsuppdrag; UAV; SAR; YOLO; EfficientDet; TensorFlow;

    Abstract : Unmanned Aerial Vehicles (UAVs) could play an important role in Search & Rescue (SAR) operations thanks to their ability to cover large, remote, or inaccessible search areas quickly without putting any personnel at risk. As UAVs are becoming autonomous, the problem of identifying humans in a variety of conditions can be solved with computer vision implemented with a thermal camera. READ MORE

  4. 23. Analysis of Aircraft Emissions Based on Flight Trajectory : ATR 72-500 trajectory and emission study

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Forsberg; Carl-Michael Sundberg; [2022]
    Keywords : trajectory; emissions; Boeing Fuel Flow;

    Abstract : Emissions related to aviation have during the last decades become an important topic of discussion. Besides carbon dioxide ($CO_2$) which is the major pollutant from air travel, other gas emissions such as hydrocarbons ($HC$), nitrogen oxides ($NO_x$), carbon monoxide ($CO$) and sulfur oxides ($SO_x$) also need to be investigated.

  5. 24. Vegetation cover change on Tindfjöll mountains, Iceland, assessed by aerial photographs, topography, and climate

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Guðrún Guðjónsdóttir; [2022]
    Keywords : Environmental changes; High Latitudes; Physical Geography; Ecosystem sciences; GIS; Climate Change; Vegetation change; Vegetation cover; Earth and Environmental Sciences;

    Abstract : Guðrún Guðjónsdóttir Climate change is having a great impact on the fragile High Latitude environment where warming is occurring at a rate at least double the global average. It is urgent to understand the relationship between climate and vegetation cover, which is playing an important role, as a carbon sink, for biodiversity, and for protecting against natural hazards.

  6. 25. Converting an Automobile Engine to an Aircraft Engine

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Gabriel Kronberg; [2022]
    Keywords : Piston Engine; Tiny Friendly Giant; Aviation Emissions; Engine Cooling; GREET; BFFM2; Sustainable Aviation Fuel; Engine Conversion; Emission Estimation; Trade Study; Kolvmotor; Tiny Friendly Giant; Flygutsläpp; Motorkylning; GREET; BFFM2; Hållbart flygbränsle; Motorkonvertering; Utsläppsupskattning; Paramterstudie;

    Abstract : This project evaluates the opportunity to convert a three-cylinder automobile piston engine (the Tiny Friendly Giant) to an aircraft engine from an environmental and practical point of view. The problem of increased emissions from aviation calls for technical and socioeconomic solutions, which is the reason why this report is written. READ MORE
