   Sammanfattning : Torture in the past is the subject of this dissertation. The aim of the study is to discuss one of the grand narratives of Swedish history. In an evolutionary frame Sweden has been put forward as a country which early developed judicial security for citizens. LÄS MER

3. 2. Vision Based Perception for Mechatronic Weed Control

   Författare :Björn Åstrand; David Slaughter; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vision-based perception; Plant recognition; Row following; Weed Control; Mechatronics in agriculture; Mobile robots;

   Sammanfattning : The use of computer-based signal processing and sensor technology to guide and control different types of agricultural field implements increases the performance of traditional implements and even makes it possible to create new ones. This thesis increases the knowledge on vision-based perception for mechatronic weed control. LÄS MER

5. 4. Vision-Based Perception for Localization of Autonomous Agricultural Robots

   Författare :Stefan Ericson; Björn Åstrand; Gert Kootstra; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production and Automation Engineering; Produktion och automatiseringsteknik; INF201 Virtual Production Development; INF201 Virtual Production Development;

   Sammanfattning : In this thesis Stefan investigates how cameras can be used for localization of an agricultural mobile robot. He focuses on relative measurement that can be used to determine where a weeding tool is operating relative a weed detection sensor. LÄS MER

7. 5. Interpretation and Alignment of 2D Indoor Maps : Towards a Heterogeneous Map Representation

   Författare :Saeed Gholami Shahbandi; Björn Åstrand; Roland Philippsen; Antanas Verikas; Patric Jensfelt; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Mobile Robots; Autonomous Robots; Robot Perception; Robotic Mapping; Map Interpretation; Semantic Mapping; Place Categorization; Place Labeling; Semantic Annotation; Map Alignment; Region Segmentation; Region Decomposition; Map Representation; Heterogeneous Representation;

   Sammanfattning : Mobile robots are increasingly being used in automation solutions with notable examples in service robots, such as home-care, and warehouses. Autonomy of mobile robots is particularly challenging, since their work space is not deterministic, known a priori, or fully predictable. LÄS MER
