1. 1. Fundamental Estimation and Detection Limits in Linear Non-Gaussian Systems

   Författare :Gustaf Hendeby; Fredrik Gustafsson; Niclas Bergman; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; Detection; Linear systems; Non-Gaussian; Limits; GLR; CRLB; Automatic control; Reglerteknik;

   Sammanfattning : Many methods used for estimation and detection consider only the mean and variance of the involved noise instead of the full noise descriptions. One reason for this is that the mathematics is often considerably simplified this way. LÄS MER

3. 2. On Integrity Monitoring of Integrated Navigation Systems

   Författare :Jan Palmqvist; Fredrik Gustafsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In civil aviation a new philosophy for flight safety and traffic management is under development. The goal is to enable an expected increase in air traffic density by reducing aircraft separation. The accuracy of the position estimate determined by the navigation system in each aircraft determines this separation. LÄS MER

4. 3. Change detection in metal oxide gas sensor signals for open sampling systems

   Författare :Sepideh Pashami; Achim Lilienthal; Marco Trincavelli; Giorgio Sberveglieri; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal oxide sensors; Open Sampling System; change point detection; gas dispersion simulation; environmental monitoring; Computer Science; Datavetenskap;

   Sammanfattning : This thesis addresses the problem of detecting changes in the activity of a distant gas source from the response of an array of metal oxide (MOX) gas sensors deployed in an Open Sampling System (OSS). Changes can occur due to gas source activity such as a sudden alteration in concentration or due to exposure to a different compound. LÄS MER
