  2. 1. The Core of Aerial Robotic Workers : Generalized Modeling, Estimation, and Control

    Author : Emil Fresk; George Nikolakopoulos; Thomas Gustafsson; Ming Cao; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial robotics; generalized modeling; generalized estimation; generalized control; Reglerteknik; Control Engineering;

    Abstract : In this thesis we are going to explore what the operational core, both mathematically and algorithmically, of an Aerial Robotic Worker consists of, in order to estimate its egomotion and parameters, and adaptively control the aerial vehicle. Moreover, the aim of this thesis is to be a condensed reference for the corresponding areas of aerial robotics, in order to provide a stable and complete foundation on which one can continue research on.

  5. 3. Estimation and Detection with Applications to Navigation

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

    Abstract : 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. READ MORE

  6. 4. Contributions to generalized Wilcoxon rank tests

    Author : Marie-Louise Öhman; Hans Nyquist; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Censored data rank sum tests; Gehan s test; Generalized Wilcoxon test; Jackknifing; Two sample problem; Simulation; Survival data; Variance estimation; Influence function; Gross error sensitivity; Sensitivity curve; Misclassification; Statistics; computer and systems science; Statistik; data- och systemvetenskap; Statistics; statistik;

    Abstract : In unbalanced small sample size problems with right censorings, the variance estmators of linear rank statistics, may be biased. This is the case with the commonly applied variance estimators for the generalized Wilcoxon rank test statistics of Gehan and Prentice. READ MORE

  7. 5. Essays on Sample Surveys : Design and Estimation

    Author : Edgar Bueno; Per Gösta Andersson; Maria Giovanna Ranalli; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; GREG estimator; mixture distribution; probability proportional to size sampling; sampling algorithms; sampling design; sampling strategy; survey sampling; stratified sampling; Statistics; statistik;

    Abstract : Sampling is a core stage in every survey. A sampling design carefully elaborated may imply not only a more accurate estimation of the parameters of interest, but also a reduction in the required sample size in a study. In this thesis we consider two particular but connected subjects. READ MORE
