1. 1. Optimization of Unmanned Aerial Vehicles : Expanding the Multidisciplinary Capabilities

   Författare :Athanasios Papageorgiou; Johan Ölvander; Mehdi Tarkian; Kristian Amadori; Mikael Thellner; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Over the last decade, Unmanned Aerial Vehicles (UAVs) have experienced an accelerated growth, and nowadays they are being deployed in a variety of missions that have traditionally been covered by manned aircraft. This unprecedented market expansion has created new and unforeseen challenges for the manufacturing industry which is now called to further reduce the idea-to-market times while simultaneously delivering designs of even higher performance.

3. 2. Semantic mapping using virtual sensors and fusion of aerial images with sensor data from a ground vehicle

   Författare :Martin Persson; Achim Lilienthal; Javier González; Örebro universitet; []
   Nyckelord :semantic mapping; aerial image; mobile robot; supervised learning; semi-supervised learning; TECHNOLOGY; TEKNIKVETENSKAP; Industriell mätteknik; Industrial Measurement Technology;

   Sammanfattning : In this thesis, semantic mapping is understood to be the process of putting a tag or label on objects or regions in a map. This label should be interpretable by and have a meaning for a human. The use of semantic information has several application areas in mobile robotics. LÄS MER

4. 3. Perception Aware Guidance Framework for Micro Aerial Vehicles

   Författare :Christoforos Kanellakis; George Nikolakopoulos; Danica Kragic; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perception driven control for MAVs; aerial inspection; vision based guidance for aerial manipulation; robots in low-light environments; Reglerteknik; Control Engineering;

   Sammanfattning : Micro Aerial Vehicles (MAVs) are platforms that have received significant research resources within robotics community, since they are characterized by simple mechanical design and versatile movement. These platforms possess capabilities that are suitable for complex task execution, in situations which are impossible or dangerous for the human operator to perform, as well as to reduce the operating costs and increase the overall efficiency of the operation.

5. 4. Handling demand-capacity imbalances in aerial vehicle traffic

   Författare :Leonid Sedov; Tobias Andersson Granberg; Valentin Polishchuk; Joost Ellerbroek; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : It is expected that the number of drones used in both commercial and leisure operations will grow significantly in the coming years, which raises the need for a solid framework for management of this traffic. Unmanned traffic management (UTM) is a system for handling autonomous drone flights over urban areas. LÄS MER

7. 5. The spatial structure of genetic and morphometric variation in Corylus avellana (Betulaceae): pattern and scale

   Författare :Helena Persson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; taxonomy; morphology; Systematic botany; Öland; clonal structure; marginal and central populations; image analysis; aerial photographs; morphometric variation; allozymes; Corylus avellana; genetic variation;

   Sammanfattning : In the present thesis, I investigated the spatial structure of genetic and morphometric variation in the widespread wind-pollinated shrub Corylus avellana (L.) Betulaceae, hazel, and related the variation to geographic distribution and different spatial scales. LÄS MER
