1. 1. Stereoscopic Label Placement : Reducing Distraction and Ambiguity in Visually Cluttered Displays

   Författare :Stephen D. Peterson; Anders Ynnerman; Matthew Cooper; John Wann; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Label placement; user interfaces; stereoscopic displays; augmented reality; virtual reality; visual clutter; Computer science; Datavetenskap;

   Sammanfattning : With increasing information density and complexity, computer displays may become visually cluttered, adversely affecting overall usability. Text labels can significantly add to visual clutter in graphical user interfaces, but are generally kept legible through specific label placement algorithms that seek visual separation of labels and other objects in the 2D view plane.

3. 2. Hardness of Approximating Constraint Satisfaction Problems and Their Variants in Presence of Additional Structural Assumptions

   Författare :Aleksa Stankovic; Johan Håstad; Per Austrin; Luca Trevisan; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hardness of Approximation; Approximation Algorithms; Label Cover; Vertex Cover; Unique Games Conjecture; Max-3-Lin; Universal Factor Graphs; Regular Constraint Satisfaction Problems; Inapproximerbarhet; Approximationsalgoritm; Label Cover; Vertex Cover; Unique Games Conjecture; Max-3-Lin; Universell Faktorgraf; Regelbundna Begränsningsproblem; Datalogi; Computer Science;

   Sammanfattning : This thesis studies how the approximability of some fundamental computational problems is affected by some additional requirements on the structure of the inputs. The problems studied in this thesis belong or are closely related to constraint satisfaction problems (CSPs), which are considered to be one of the most fundamental problems in theoretical computer science.

4. 3. Positioning Algorithms for Surveillance Using Unmanned Aerial Vehicles

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

   Sammanfattning : 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. LÄS MER

5. 4. Polarization characteristics in polyelectrolyte thin film capacitors : Targeting field-effect transistors and sensors

   Författare :Oscar Larsson; Xavier Crispin; Magnus Berggren; Nathaniel Robinson; Ludvig Edman; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Polymers are very attractive materials that can be tailored for specific needs and functionality. They can for instance be made electrically insulating or (semi)conducting, with specific mechanical properties. Polymers are often processable from a solution, which enables the use of low-cost manufacturing techniques to fabricate polymer devices. LÄS MER

7. 5. 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
