2. 1. Design Optimization of Unmanned Aerial Vehicles : A System of Systems Approach

   Author : Athanasios Papageorgiou; Johan Ölvander; Mehdi Tarkian; Michael Kokkolaras; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Over the last years, Unmanned Aerial Vehicles (UAVs) have gradually become a more efficient alternative to manned aircraft, and at present, they are being deployed in a broad spectrum of both military as well as civilian missions. This has led to an unprecedented market expansion with new challenges for the aeronautical industry, and as a result, it has created a need to implement the latest design tools in order to achieve faster idea-to-market times and higher product performance.

4. 2. Automation in forestry : development of unmanned forwarders

   Author : Ola Ringdahl; Thomas Hellström; Tomas Nordfjell; Arto Visala; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Computer science; Datavetenskap; Forest engineering; Skogsteknik; computer and systems sciences; data- och systemvetenskap;

   Abstract : For the last 50 year, forestry operations have become more and more mechanized. In modern forestry in Europe two machines are typically used; a harvester that fells, debranches and cross-cuts the trees into logs and a forwarder that transports them to the nearest road. READ MORE

5. 3. Fuzzy Control for an Unmanned Helicopter

   Author : Bourhane Kadmiry; Dimiter Driankov; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Helicopter; Robust control; Fuzzy gain scheduling; Gradient descent method; Computer science; Datavetenskap;

   Abstract : The overall objective of the Wallenberg Laboratory for Information Technology and Autonomous Systems (WITAS) at Linköping University is the development of an intelligent command and control system, containing vision sensors, which supports the operation of a unmanned air vehicle (UAV) in both semi- and full-autonomy modes. One of the UAV platforms of choice is the APID-MK3 unmanned helicopter, by Scandicraft Systems AB. READ MORE

6. 4. Optimization of Unmanned Aerial Vehicles : Expanding the Multidisciplinary Capabilities

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

   Abstract : 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.

7. 5. Positioning Algorithms for Surveillance Using Unmanned Aerial Vehicles

   Author : Per-Magnus Olsson; Patrick Doherty; Lars Karlsson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unmanned aerial vehicles; surveillance; communication relay; label- correcting; dual ascent; Steiner trees; Computer science; Datalogi;

   Abstract : Surveillance is an important application for unmanned aerial vehicles (UAVs). The sensed information often has high priority and it must be made available to human operators as quickly as possible. Due to obstacles and limited communication range, it is not always possible to transmit the information directly to the base station. READ MORE
