1. 1. Estimation and Detection with Applications to Navigation

   Författare :David Törnqvist; Fredrik Gustafsson; Hugh Durrant-Whyte; Linköpings universitet; []
   Nyckelord :Navigation; SLAM; Particle Filter; Estimation; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The ability to navigate in an unknown environment is an enabler for truly utonomous systems. Such a system must be aware of its relative position to the surroundings using sensor measurements. It is instrumental that these measurements are monitored for disturbances and faults. LÄS MER

3. 2. Statistical Fault Detection with Applications to IMU Disturbances

   Författare :David Törnqvist; Fredrik Gustafsson; Alexander Medvedev; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault detection; Linear systems; State-space models; Signal processing; State estimation; Fault observability; Inertial Measurement Unit; Automatic control; Reglerteknik;

   Sammanfattning : This thesis deals with the problem of detecting faults in an environment where the measurements are affected by additive noise. To do this, a residual sensitive to faults is derived and statistical methods are used to distinguish faults from noise. LÄS MER

4. 3. Continuous Models for Cameras and Inertial Sensors

   Författare :Hannes Ovrén; Per-Erik Forssen; Klas Nordberg; David Törnqvist; Frank Dellaert; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Using images to reconstruct the world in three dimensions is a classical computer vision task. Some examples of applications where this is useful are autonomous mapping and navigation, urban planning, and special effects in movies. LÄS MER

5. 4. Tracking and Planning for Surveillance Applications

   Författare :Per Skoglar; Fredrik Gustafsson; David Törnqvist; Umut Orguner; Simon Maskell; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; target tracking; sensor control; planning; surveillance; vision sensor;

   Sammanfattning : Vision and infrared sensors are very common in surveillance and security applications, and there are numerous examples where a critical infrastructure, e.g. a harbor, an airport, or a military camp, is monitored by video surveillance systems. LÄS MER

7. 5. Omöjliga familjen : Ideologi och fantasi i svensk reproduktionspolitik

   Författare :Helena Tinnerholm Ljungberg; Maud Eduards; Sara Edenheim; Cecilia Åse; Maria Törnqvist; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; assisted reproduction; human reproduction; logics approach; new reproductive techniques; political discourse theory; psychoanalysis; Swedish politics; queer theory; reproduction policy; Political Science; statsvetenskap;

   Sammanfattning : The relationship between the state and the people is a central theme in political theory. Discussions in this field have often centered on how a people can come to constitute a state. Less attention, however, has been directed toward the state’s role in constituting and recreating its people. LÄS MER
