2. 1. Planar segmentation for Geometric Reverse Engineering using data from a laser profile scanner mounted on an industrial robot

   Author : Mohamed Rahayem; Björn Arén; Johan Kjellander; Mathias Broxvall; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geometric Reverse Engineering; 3D measurement systems; laser scanner; planar segmentation; region-growing; Computer and systems science; Data- och systemvetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Abstract : Laser scanners in combination with devices for accurate orientation like Coordinate Measuring Machines (CMM) are often used in Geometric Reverse Engineering (GRE) to measure point data. The industrial robot as a device for orientation has relatively low accuracy but the advantage of being numerically controlled, fast, flexible, rather cheap and compatible with industrial environments.

4. 2. Reactive navigation of an autonomous vehicle in underground mines

   Author : Johan Larsson; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mobile Robots; Computer science; Datavetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer and Systems Science; Data- och systemvetenskap;

   Abstract : In most underground mines, LHD (Load-Haul-Dump) vehicles are used to transportore from the stope or muck-pile to a dumping point, and are typically operated by a human who is sitting on-board the vehicle. Generally, an underground mine does not offer the best working environment for humans, and the job of an LHD operator can be characterised as Three D: Dangerous, Dirty and Dull. READ MORE

5. 3. Security Analysis of Web and Embedded Applications

   Author : Benjamin Eriksson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Web application scanning; Content Security Policy; Vulnerabilities; Android Automotive;

   Abstract : As we put more trust in the computer systems we use the need for security is increasing. And while security features like HTTPS are becoming commonplace on the web, securing applications remains dicult. This thesis focuses on analyzing dierent computer ecosystems to detect vulnerabilities and develop countermeasures. READ MORE

6. 4. An industrial robot as carrier of a laser profile scanner : motion control, data capturing and path planning

   Author : Sören Larsson; Johan Kjellander; Wolfgang H. Koch; Örebro universitet; []
   Keywords : Geometric reverse engineering; Laser scanning; Industrial robot; Path planning; CAD; 3D measurement systems; Mechanical engineering; Maskinteknik; TECHNOLOGY; TEKNIKVETENSKAP; Mechanical Engineering; Maskinteknik;

   Abstract : Geometric Reverse Engineering (RE) is concerned with the problem of creating CAD-models of real objects by measuring point data from their surfaces. In the aim of creating a fully automatic RE system there is a need to automate also the measuring process. READ MORE

7. 5. Food for Thought : Essays on Green Public Procurement and the Market for Organic Food

   Author : Hanna Lindström; Sofia Lundberg; Tommy Lundgren; Janne Tukiainen; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Organic food policy; agricultural policy; Green Public Procurement; environmental policy; consumer demand; demand system; price transmission; survey data; retail scanner data;

   Abstract : Paper [I] In this paper, we study a Green Public Procurement (GPP) policy decided by the Swedish government in 2006, stating objectives related to organic farming. The policy aims to increase the public sector's organic food purchases, in order to incentivise Swedish farmers to convert to organic practices, thereby contributing to national environmental quality objectives.
